Air Cooled Chillers
The air-cooled chiller, also known as the air-cooled box-type industrial chiller, is a kind of equipment for various industries with different processes, and the equipment is cooled to achieve the purpose of the process. It is widely used in electronics, electroplating, chemical, mechanical, chemical, laser, pharmaceutical, medical and other industries. Because the source of its heat exchange is gas, it is equipped with a special fan, so it is called an air-cooled chiller.
The industrial air-cooled chiller is mainly suitable for plastics. It can precisely control the temperature of the plastic molding mold to shorten the molding cycle and accelerate the product shape. Using the principle of cold and heat exchange for cooling, the temperature can be quickly cooled and the temperature control is stable. And not affected by environmental factors, it is an indispensable configuration equipment in modern industry.
Characteristics of Air-Cooled Chillers
- The air-cooled chiller does not need to be connected to a cooling tower, and is suitable for environments with poor impurities. (Impurities are easily mixed in the cold water tower, and the dust will cause the cooling water circulation circuit to be blocked, resulting in a decrease in cooling capacity).
- Air-cooled chillers are most suitable for areas with poor water quality, which can save other accessories such as cold water towers.
- The use of large-capacity condenser makes it easier and more convenient to operate.
- The floor space is reduced to a greater extent, and the installation is very convenient.
- The air-cooled chiller adopts the design of the upper air outlet.

Difference between Air Cooled Chiller and Water Cooled Chiller
1. In terms of the size of the equipment, due to the difference in the working principle between the two, the air-cooled chiller is smaller than the water-cooled chiller in terms of the size of the equipment, and the use and later maintenance Also relatively simpler.
2. From the perspective of the efficiency of the equipment, the cooling effect of the water-cooled chiller is stronger than that of the air-cooled chiller, and the power consumption is also less.
3. The price of water-cooled chillers is relatively low, but a special equipment room needs to be built in use, while air-cooled chillers do not. Therefore, if there is no suitable venue, it is more suitable to choose air-cooled equipment.
Installation Location Selection of Air-Cooled Chillers
The distance between the air-cooled chiller and the temperature-controlled equipment: the distance between the air-cooled chiller and the temperature-controlled equipment should be minimized. This has the advantage of reducing the pressure drop and cooling loss of the chilled water in the pipeline, and It is convenient to operate the device when the device does not have a remote control function.
Influence of the noise of the air-cooled chiller: The noise of the air-cooled chiller mainly comes from the compressor, the circulating water pump and the fan, among which the noise of the fan is the main one. The noise of conventional small air-cooled chillers is relatively small, generally around 65dB(A), and can be used in ordinary indoor environments. If it is used in places with quiet requirements, such as laboratories, you need to consider chillers. noise reduction problem. For air-cooled chillers with more than 20HP, it is recommended to install them in an outdoor environment slightly far from the working environment of personnel.
Water supply and drainage requirements: The air-cooled chiller may need to supplement a certain amount of circulating water during use and later maintenance, so the installation location should consider the water source for automatic water supply, and the circulating water can be easily discharged during equipment maintenance. If the air-cooled chiller adopts the method of manual water replenishment, you only need to consider the drainage problem of the equipment.
Chiller installation environment: In terms of heat dissipation conditions, it is better to install the air-cooled chiller outdoors than indoors, because there is a good ventilation environment outdoors, and the heat from the equipment can be discharged in time, but due to the outdoor equipment It adopts a windproof and rainproof structure design, so the price will be more expensive than that of ordinary chillers. In addition, in order to facilitate the operation, it is very necessary to remotely connect the control and fault feedback parts of the chiller to the room.
Maintenance and Inspection of Air-Cooled Chillers
Check the stability of voltage and current.
Check the compressor regularly.
Carry out the necessary acceptance tests for the chiller. Air tightness test first, then vacuum test. Item test first, then complete machine test.
Regular cleaning
In addition to checking the technical performance of the chiller, attention should also be paid to protecting the clean appearance of the unit and the cleanliness of the work site. When the air-cooled chiller runs for 6 months, it is necessary to clean the entire system, such as pipes, filters, condensers, fans, etc., especially the fans. Like our commonly used fans, dust is full of dust and affects heat dissipation, so the cooling efficiency will be reduced. directly lower.
Check the instrument regularly
The temperature control meter is out of control, replace the temperature control meter, high-voltage fault, poor heat dissipation, the radiator is too dirty, clean the radiator, and the wind is not good, improve the ventilation conditions , replace the high pressure engine.
Regularly check whether the refrigerant is reduced
Judging according to the high pressure and low pressure pressure gauge values on the front of the air-cooled chiller. When the chiller is in normal operation, the high pressure is 11-17kg and the low pressure is 3-5kg is the normal range. In the shutdown state, both high pressure and low pressure are around 0.6kg.
The high-efficiency refrigeration function of air-cooled chiller products is inseparable from the daily maintenance and safety inspection of the product, so it is very important to regularly check the operation of the air-cooled chiller. In addition to the above major inspection aspects, pay attention to check the oil level and oil temperature of each compressor, check the main power supply voltage and current, and check whether the set value of the chilled water supply temperature is appropriate. If there are problems, make changes in time.
