In the production work of various industries, the commonly used chillers are air-cooled chillers or water-cooled chillers. These two types of chillers are the most common in the market.
Air-cooled and water-cooled industrial-grade chillers are critical for industrial processes, such as plastics, pharmaceuticals, commercial printing, and transportation manufacturing. Our clients also rely on them for brewing processes, dairy farm operations, and medical equipment processing.
Both air-cooled and water-cooled chillers work by removing the heat from your processes so that your equipment stays cool, so they can keep running strong. In this post, we’re providing an insider look at the main components of a process chiller and the importance of each one.
If you’ve ever wondered what’s inside a chiller, here are the four main components of both air-cooled and water-cooled process chillers to know about the 4main components of chillers and basic working principles of a water chiller.
The main engine of chiller cold compressor is screw and centrifugal compressor, and the commercial engine is scroll compressor.
In the refrigeration industry, common compressors can be divided into the following categories.
Rotor compressor is a positive-displacement rotary gas compressor. The compression volume is defined by the trochoidally rotating rotor mounted on an eccentric drive shaft with a typical 80 to 85% adiabatic efficiency.
Piston Compressor is a positive-displacement compressor that uses pistons driven by a crankshaft to deliver gases at high pressure.
Screw compressor is a type of gas compressor, such as an air compressor, that uses a rotary-type positive-displacement mechanism. These compressors are common in industrial applications and replace more traditional piston compressors where larger volumes of compressed gas are needed, e.g. for large refrigeration cycles such as chillers, or for compressed air systems to operate air-driven tools such as jackhammers and impact wrenches.
Magnetic suspension centrifugal compressor is discharged from the air conditioner compressor through high temperature and high pressure freon, enters the condenser, releases heat to the copper tube cooling water, condenses into medium temperature and high pressure Freon liquid, and then depressurizes to low temperature and low pressure liquid through the shut-off valve, enters the evaporator, absorbs heat from the frozen water flowing through the copper tube in the evaporator shell, gasifies into low temperature and low pressure gas, and then inhales into the compressor, which is used in the compressor Through this cycle, the purpose of cooling is achieved.
Evaporator of industrial chiller
Ordinary, there are 3 kinds of Evaporator we would use: Dry Evaporator / Full liquid Evaporator / Fall Film Evaporator
The working principle is the refrigerant flows in the tube and the water flows outside the tube cluster. Generally, the problem of oil accumulation does not exist when the lubricating oil from the shell enters the compressor with the refrigerant.
The dry evaporator is mainly composed of heat transfer tube, stripper, water discharge tube, refrigerant inlet tube, refrigerant outlet tube, refrigerant water inlet tube, refrigerant water outlet tube, left and right end caps and shell.
1.The heat transfer coefficient is high and the temperature difference is small;
2.The amount of refrigerant filled is less, generally only about 1 / 3 of that of full liquid type;
3.When the temperature is near 0 ℃, the water will not freeze, the heat transfer coefficient is 4.low and the temperature difference at the end is large;
5.Scale is easy to pay on the surface of evaporator copper tube, and is not easy to clean;
The refrigerant flows outside the pipe and the water flows inside the pipe. It is composed of shell, evaporation tube (high efficiency tube), tube sheet, support plate, etc.
1.The heat transfer coefficient is high and the temperature difference is small;
2.The water goes through the pipe and is easy to clean;
3.The refrigerant liquid basically fills the tube bundle, and the charge quantity is large;
4.The return oil of full liquid evaporator is difficult and unstable;
5.When the evaporation temperature of refrigeration system is lower than 0 ℃;
6.The water in the tube is easy to freeze and destroy the evaporation tube;
7.The static liquid column of the liquid in the full liquid evaporator increases the saturated evaporation temperature at the bottom.
The refrigerant is evenly separated from the distributor, forms a liquid film on the surface of the heat exchange tube, absorbs the heat in the tube and evaporates, and water flows in the tube, which is composed of distributor, shell, evaporation tube (high efficiency tube), tube sheet, support plate, etc.
1.High heat transfer coefficient and small end temperature difference (better than full liquid, better than dry type);
2.The lubricating oil accumulates at the bottom of the container and is easy to return due to its high concentration;
3.Avoid the liquid column in the full liquid evaporator to increase the saturated evaporation temperature at the bottom;
4.The main pipe phenomenon of falling film is avoided, the heat transfer is more uniform and the efficiency is higher;
5.The water goes through the pipe and is easy to clean;
6.When the evaporation temperature of refrigeration system is lower than 0 ℃, the water in the tube is easy to freeze and destroy the evaporation tube.
It is a part of refrigeration system, belonging to a kind of heat exchanger, which can convert gas or steam into liquid and transfer the heat in the pipe to the air near the pipe in a very fast way. The condenser is a heat releasing device, which transfers the heat absorbed in the evaporator together with the heat converted by the compressor work to the cooling medium. The working process of condenser is an exothermic process, so the temperature of condenser is higher.
It is composed of built-in separator, shell, evaporation tube (high efficiency tube), tube sheet, support plate, subcooler, etc.
According to the different cooling medium, condensers can be divided into three types: water cooling type, air cooling type and evaporation type.
Water cooled condenser takes water as cooling medium and takes away condensation heat by the temperature rise of water. The cooling water is generally recycled, but the cooling tower or cool pool should be set in the system. According to its structure, water-cooled condenser can be divided into shell and tube condenser and tube and tube condenser.
The main features are as follows:
1) Because of the large cooling flow and high flow rate, the heat transfer coefficient is high.
2) Vertical installation covers a small area and can be installed outdoors.
3) The cooling water flows directly and the flow rate is large, so the requirement of water quality is not high. Generally, the common water can be used as cooling water.
4) The scale in the pipe is easy to clean, and it is not necessary to stop the refrigeration system.
5) The temperature rise of the cooling water in the vertical condenser is generally only 2-4 ℃, and the logarithmic average temperature difference is generally about 5-6 ℃, so the water consumption is large. And because the equipment is placed in the air, the pipe is easy to be corroded, and the leakage is easy to be found.
It has the similar shell structure with the vertical condenser, the main difference lies in the horizontal placement of the shell and the multi-channel flow of water.
Horizontal condenser is widely used in refrigeration system and freon refrigeration system, but its structure is slightly different. According to the horizontal condenser, the cooling tube is smooth seamless tube, while the cooling tube of Freon horizontal condenser is generally low rib copper tube.
This is due to the low exothermic coefficient of Freon. It is worth noting that some freon refrigeration units generally do not have liquid storage tanks. But only use a few rows of tubes at the bottom of the condenser, which is also used as a liquid storage tank.
The vapor of the refrigerant enters the cavity between the inner and outer tubes from above, condenses on the outer surface of the inner tube, and the liquid flows down at the bottom of the outer tube in turn, and flows into the liquid reservoir from the lower end.
The cooling water enters from the lower part of the condenser and flows out from the upper part of the condenser through the inner tubes of each row in turn. This kind of condenser has the advantages of simple structure, easy manufacture, and good heat transfer effect because of single tube condensation and opposite medium flow direction.
Its disadvantage is that the metal consumption is large, and when the number of longitudinal tubes is large, the lower tube is filled with more liquid, so that the heat transfer area can not be fully utilized.
In addition, the compactness is poor, the cleaning is difficult, and a large number of connecting elbows are needed. Therefore, this kind of condenser has been rarely used in refrigeration device. Casing condenser is still widely used in small Freon air conditioning units.
Air cooled condenser takes air as cooling medium and takes away condensation heat by air temperature rise. This kind of condenser is suitable for the situation of extreme lack of water or water supply, and is commonly used in small freon refrigeration units. According to the different ways of air flow, it can be divided into natural convection and forced convection.
The heat transfer of evaporative condenser mainly depends on the evaporation of cooling water in the air to absorb the latent heat of gasification. According to the way of air flow, it can be divided into suction type and pressure type.
The evaporative condenser is composed of cooling pipe group, water supply equipment, fan, water baffle and box. The cooling pipe group is a snake coil group made of seamless pipe bending, which is installed in a rectangular box made of thin steel plate. The two sides or top of the box body are provided with ventilators, and the bottom of the box body is also used as a cooling water circulating pool.
Parallel connection of evaporative condenser and shell and tube condenser:
Throttling device of chiller
The main function is to throttle and depressurize, control and regulate the refrigerant flow and superheat.
Double orifice plate: slow adjustment response; almost no adjustment ability; small energy adjustment range; low cost.
Electronic expansion valve: simple structure, small resistance, wide energy regulation, rapid response to energy efficiency regulation, high cost.
Pro tip: For low-temperature requirements, ask about electronic expansion valves (EEVs) to give you tight superheat control. They work by using a stepper motor that precisely regulates the valve’s position.
Each of these components of industrial-grade process chillers serves a vital role in cooling your equipment.

Before injection, the mold should be heated to a certain temperature. Then the plastic is not easy to solidify when it is integrated into the mold cavity in the injection molding process.
The problems like insufficient physical strength, delamination, incomplete injection and blocked flow channel are all related to the weakness of warm mold, which is the significance of warm mold.
During injection molding, the mold needs to be cooled after the whole cavity is filled with plastic. The plastic in molten state is rapidly cooled and solidified.
This is the normal definition of plastic molding chilling. But few people know the effect of cooling rate on the physical strength and internal stress of the final product.
In principle, for different injection parts, the injection mold can be cooled via a water chiller in the fastest way. The injection molding machine produced under this way will reach the best state in terms of physical strength and internal stress.
If the cooling time is too long, the physical strength of the injection molded parts will be weakened and the internal stress will be increased. It will lead to deformation of products. The most common problems are injection molded parts with thin thickness and large size such as automobile dashboard, which will cause great trouble to automobile manufacturers.
Set the same amount of raw materials for each injection molding machine. But when the product design requirements are different, the mold temperature control requirements are also different. Some special products have great requirements on internal stress and physical strength. Different mold sections require different temperature curves, which requires multiple mold temperature controller and injection molding chiller.
In the process of laser equipment running for a long time, the laser generator will generate high temperature continuously. If the temperature is too high, it will affect the normal operation of the laser generator, which is easy to be damaged.
In order to prolong the service life of the laser, it is necessary to cool the laser exciter by water circulation to ensure its normal operation under constant temperature or set temperature.
The water cooler is mainly used to cool the laser generator of the laser equipment, and control the temperature of the laser generator, so that the laser generator can work normally for a long time. Water chiller is a kind of water cooling equipment, which can provide constant temperature, constant current and constant pressure. The principle of the water chiller is to inject a certain amount of water into the internal water tank of the machine, cool the water through the refrigeration system of the water chiller, and then the water pump inside the machine will inject the low-temperature frozen water into the equipment to be cooled. The frozen water will take away the heat inside the machine, and return the high-temperature hot water to the water tank again for cooling, so as to achieve the purpose of cooling the equipment Use.
And the volumetric efficiency of the compressor decreases, resulting in the reduction of refrigeration capacity and the increase of power consumption. The higher the exhaust temperature and the higher the condensation pressure, the greater the adverse effect.
The phenomenon of high condensation pressure mainly occurs in Summer. At this time, the condensation pressure should be reduced as much as possible to ensure the economy and reliability of the system operation.
When the condensing pressure is too low, the pressure difference between the front and back of the expansion valve is too small, and the capacity of the expansion valve is reduced, resulting in the insufficient liquid supply capacity of the system refrigerant, the lack of liquid in the evaporator, and the refrigeration capacity of the system is greatly reduced, and the unit is protected under low pressure. Therefore, it is necessary to control the condensing pressure in a reasonable range, otherwise the refrigeration device will have frequent low-pressure alarm or low suction pressure alarm.
To avoid the winter operation risk through the equipment side anti freezing, cooling tower start-up and shutdown and pipeline optimization design.
Spray Water System and Internal Circulating Water System (softened water).
For the anti freezing problem of spray water system, an electric heater is usually added in the water pan, which is generally started when the spray water is lower than 5 ℃ and stops when the spray water is above 8 ℃.
The temperature probe transmits the signal to the control cabinet to automatically control the start and stop of the electric heater. The power selection of electric heater depends on circulating water volume and external air temperature.
The freezing point temperature of glycol solution should be selected below the local historical minimum temperature.
For the larger cooling system, we can consider digging a pool to put the spray water into it, which can save the power consumption due to electric heating operation.
Now more and more civil and commercial refrigeration equipment use electronic expansion valve to replace the original thermal expansion valve. The electronic expansion valve and the thermal expansion valve have the same basic use, but different in performance.
At present, the regulating range of thermal expansion valve is generally narrow. The heat pump unit should not only refrigeration, but also heating, and the ambient temperature range of the suitable occasions is from – 15 ℃ ~ + 43 ℃, 해당 냉매 증발 온도는 다음 범위에서 작동합니다. – 25℃ – 5 ℃. In addition, if there are multiple compressors in the refrigeration circuit, the number of compressors in operation will change accordingly with the change of user load, resulting in dramatic change of refrigerant flow.
Therefore, a single thermal expansion valve is far from competent for the operation of large heat pump units. At present, many large-scale heat pump products are designed with single loop and single compressor, and the expansion valve system with independent refrigeration mode and heating mode is adopted, which will increase the complexity and manufacturing cost of the system. The electronic expansion valve can be adjusted accurately in the range of 15% ～ 100%.
According to the current use effect, a single electronic expansion valve can meet the regulation of heat pump unit under the above conditions. The adjustable range can be set according to the characteristics of different products, which increases the flexibility.
For the thermal expansion valve, generally only the superheat at the evaporator outlet can be controlled. In the semi closed and fully closed compressor system, the control point can be set not only at the evaporator outlet, but also at the compressor suction port, which can control the suction superheat of the compressor to ensure the efficiency of the compressor.
For thermal expansion valve, its superheat setting value is generally set by the manufacturer in the manufacturing process, usually 5 ℃, 6 ℃ or 8 ℃. The superheat degree of the electronic expansion valve can be set manually according to the different characteristics of the product. For example, the superheat of the evaporator outlet is set to 6 ℃, and the superheat of the compressor suction can be set to 15 ℃, which is very flexible.
The superheat setting values of thermal expansion valve are all set under standard conditions. However, due to the characteristics of charging working fluid, when the system deviates from the standard working condition, the superheat will deviate from the set value with the change of condensation pressure, which will not only cause the decrease of system efficiency, but also cause the fluctuation of the system. The superheat degree of the electronic expansion valve is set by the controller artificially, and the actual superheat degree of the system is calculated by the parameters of the control point collected by the sensor, so there is no such problem.
The superheat control of thermal expansion valve is based on the state of the current control point, which is determined by the characteristics of working fluid filled. It can not judge the change trend of the system. The control logic of the electronic expansion valve can adopt various intelligent control systems according to the design and manufacturing characteristics of different products. It can not only adjust the current state of the system, but also distinguish the characteristics of the system according to the change rate of superheat degree and other parameters. The corresponding control methods are adopted for different system change trends. Therefore, its response speed and pertinence to system changes are superior to thermal expansion valve.
The thermal expansion valve is driven by taking advantage of the thermal characteristics of the filling working medium, so its opening and closing characteristics are as follows:
(1) The sensitivity of reaction and the speed of opening and closing are slow.
(2) Generally speaking, the opening and closing speed of thermal expansion valve is relatively consistent.
(3) In the process of unit start-up, there is static superheat. The superheat (SH) of thermal expansion valve is composed of static superheat (SS) and opening superheat (OS). Due to the existence of static superheat, there will be a tendency to delay the opening of thermal expansion valve during startup.
The driving mode of the electronic expansion valve is that the controller calculates the parameters collected by the sensor, sends the regulation command to the driving board, and the driving board outputs the electric signal to the electronic expansion valve to drive the action of the electronic expansion valve. It takes only a few seconds for the electronic expansion valve to change from fully closed to fully open. It has fast reaction and action speed, and there is no static superheat phenomenon. Moreover, the opening and closing characteristics and speed can be set manually, which is especially suitable for the use of heat pump units with severe fluctuation of working conditions.
In order to prevent compressor overload caused by excessive refrigerant pressure and flow at evaporation side during the initial start-up of the unit, the thermal expansion valve is generally equipped with mop function, that is, the expansion valve can only be opened when the evaporation pressure is lower than the set value. However, compared with the electronic expansion valve, its function is still monotonous.
The structure of the electronic expansion valve can be regarded as the organic combination of throttle mechanism and solenoid valve, and it can be adjusted by the controller. Therefore, according to different product characteristics, it shows the diversity and superiority of its control function under the conditions of unit start-up, load change, defrosting, shutdown and fault protection. For example: the electronic expansion valve to regulate the refrigerant flow can not only control the evaporator, but also can be used to adjust the condenser.
When the evaporation condition allows, if the condensation pressure is too high, the expansion valve can be properly closed to reduce the refrigerant flow in the system and the condenser load, so as to reduce the condensation pressure and realize the efficient and reliable operation of the unit.

냉각 장치가 최대한 오랫동안 작동할 수 있는지 확인하려면 산업용 냉각수 냉각기의 모든 설치 요구 사항을 확인해야 합니다.
산업용 냉각기는 방열 모드에 따라 두 가지 범주로 나눌 수 있습니다. 1. 수냉 장치; 2. 공기 냉각 장치.
수냉식 장치는 냉각탑과 냉각수 및 냉각수의 입구 및 출구 파이프와 연결되어야 합니다. 냉각탑과 냉각 펌프는 냉각 용량과 압축력에 따라 입구 압력 ≥ 1.5bar로 선택해야 하며 입구 및 출구 파이프의 직경은 냉각수 입구 및 출구 파이프의 직경과 일치해야 합니다.
그러나 공냉식 장치는 냉수 입구 및 출구 파이프와 보충수 공급원만 연결하면 됩니다. 전원을 연결한 후 작업을 진행할 수 있습니다. 환기가 원활해야 하며, 기기 내부로 흡입되는 것을 방지하기 위해 주변에 먼지나 이물질이 없어야 합니다.
장치에 예약된 수도관 연결 포트의 직경은 표준 크기입니다. 원격 변속기를 채택할 경우 더 큰 직경의 송수관을 연결에 사용해야 합니다. 어떤 경우에도 수도관의 직경은 연결 포트의 표준 직경보다 작아서는 안 됩니다. 그렇지 않으면 압력 경보가 울리고 압축기와 물 펌프가 크게 손상됩니다.
수도관을 연결할 때 사용자는 설치 도면을 참조하여 파이프라인을 연결하고 입구 및 출구 파이프의 위치를 확인하고 냉각수 파이프와 냉수 파이프를 구별해야 합니다. 파이프를 잘못 연결하면 장치가 손상됩니다. .전체 시스템의 정상적인 연결을 확인한 후에만 시스템을 시작하고 실행할 수 있습니다.
수도관을 기기에 연결할 때에는 커넥터나 플랜지로 연결해야 필요할 때 쉽게 제거할 수 있습니다.
호스의 일부는 수도관의 출구와 입구에 연결되어 진동 전달을 줄입니다.
허용되는 경우 수도관에 밸브를 설치하여 물 흐름을 효과적으로 제어합니다. 침전물과 이물질을 방지하기 위해 물 입구에 필터를 설치하는 것이 좋습니다.
내부 및 외부에 누출 문제가 있는지 확인하십시오. 물 입구/출구 밸브 증발기와 응축기가 완전히 열려 있습니다.
수도관은 표면의 성에로부터 보호하고 차가운 물의 온도를 유지하기 위해 충분한 단열면으로 감싸야 합니다.
겨울철에 기기 작동을 멈추면 워터펌프 및 송수관 안의 물이 얼어 기기 및 송수관이 손상될 수 있습니다. 결빙을 방지하기 위해 장치가 정지하면 워터 펌프가 효과적으로 시동될 수 있습니다. 그래도 결빙 가능성이 있는 경우에는 수도관의 물이 모두 배수됩니다. 배수가 어려울 경우 에틸렌 글리콜이나 프로판올과 같은 결빙 방지 혼합물을 사용할 수 있습니다.
기기 설치시 냉수관 장치에 바이패스관을 설치해 주세요. 냉수 배출 밸브를 낮추면 바이패스 파이프 밸브를 조정하여 펌프 압력을 완화하고 증발기의 동결을 방지할 수 있습니다.
공냉식 냉각기가 시동되어 작동할 때 시동 및 작동하기 전에 워터 펌프와 배기 팬이 정상적으로 회전하는지 주의하십시오.
장치가 작동 중일 때 압력 표시 내용에 주의하십시오. 수냉식 고압은 (1.2 ~ 1.8MPa), 저압은 (0.3 ~ 0.6MPa)입니다. 공랭식 고압은 (1.2~1.9MPa), 저압은 (0.3~0.6MPa)입니다. 값이 너무 높거나 너무 낮으면 결함이 전조이거나 부적절한 사용임을 의미합니다. 제때에 확인하시거나 제조사에 알려서 처리하시기 바랍니다. 나중에 수리하는 것보다 미리 유지관리하는 것이 좋습니다.
콘덴서의 스케일이 쉽게 생기지 않고 오랫동안 사용하기 위해서는 연수(또는 수돗물)를 냉각수로 사용하시기 바랍니다. 냉각탑을 사용하는 경우 냉각수를 정기적으로 교체해야 합니다.
냉각기의 응축기와 증발기는 일반적으로 일정 기간 사용 후 청소해야 합니다. (청소 주기는 주변 환경과 수질에 따라 다릅니다.)
기기의 출구 수온은 7~12℃로 조절하는 것이 좋습니다. 온도 컨트롤러를 조정할 때 온도가 낮으면 장치의 일부 보호 장치가 작동하지 않을 수 있다는 점에 유의하십시오.
장치의 모든 전기 제어 요소와 보호 장치는 제조업체에서 엄격하게 테스트했습니다. 점검 및 유지보수 시 사용자는 임의로 변경하거나 제거할 수 없습니다. 보호 장치 없이 강제로 작동하면 장치가 크게 손상될 수 있습니다.

Find it hard or complicate to install a water chiller? Don’t know how to pick up a right place to settle your new water chiller?
Actually , you just need to do below steps one by one.Then everything will become very simple.
Let’s do it！
Before installation, check whether the components of the unit are complete.
Select the appropriate cooling tower (air cooling type does not need cooling tower), and the capacity of cooling water pump should match the model. Please install according to the size of the body pipe, do not reduce the size of the cooling pipe, in order to avoid causing high pressure overload, affecting the cooling effect and increasing power consumption.
Correct handling method: use stacker, crane and drum. Do not drag the machine by force. Since the equipment has been debugged before leaving the factory, the system has pressure, so strong vibration is not allowed during loading and unloading, handling and installation. It is not allowed to invert, tilt or side set the unit during handling.
The water chiller is an indoor device. If the user needs to place the equipment outdoors, it should be well protected from rain and sun, and should not be directly exposed to the outside.
The installation location should be a place with stable foundation, open surroundings, ventilation, avoiding corrosion and pollution, and convenient for installation and maintenance.
Since the unit itself will generate heat, it is necessary to avoid high temperature area around the unit during installation to meet the effective heat dissipation of the equipment, especially to ensure that the condenser of air-cooled chiller is well ventilated.
Avoid placing high-power inverter, welding machine and other equipment with interference sources near the equipment, and the installation space of the unit shall not be less than the size shown in the figure below. The figure shows the minimum installation space of the unit (unit: mm).
The unit without caster at the bottom must be placed on the horizontal concrete base, and there must be no less than 3mm thick damping rubber pad between the unit and the concrete base
On the other hand, it can reduce heat emission. When placing, please support the bottom of the unit with bracket to make it ventilate smoothly and prevent rusting.
Note:
(1) the power load and grounding part shall be constructed in accordance with relevant laws and regulations
(2) The chilled water pipes of newly installed chillers must be covered with insulation layer.
