Chiller is a common refrigeration equipment widely used in industries, commerce and households. Among them, air cooled process chillers are a common type of chiller. The principle is to use a fan to blow air through the condenser, so that the refrigerant releases heat in the condenser, thereby achieving the purpose of cooling.

Composition of air cooled process chillers

Air cooled process chillers are mainly composed of compressors, condensers, expansion valves and evaporators. Among them, the compressor is the core component of the chiller, and its function is to compress the low-temperature and low-pressure refrigerant into a high-temperature and high-pressure refrigerant, thereby improving the cooling efficiency. The condenser is the place where the refrigerant releases heat under high temperature and high pressure, and its main function is to dissipate the heat of the refrigerant to the surrounding environment. The expansion valve is to reduce the temperature and pressure of the high-temperature and high-pressure refrigerant through throttling, so that the refrigerant enters the evaporator. The evaporator is the place where the refrigerant absorbs heat at low temperature and low pressure. Its main function is to absorb the heat of the refrigerant to achieve the purpose of refrigeration.

How air cooled process chillers work?

The working principle of air cooled process chillers is to use the refrigerant to change from a low-temperature and low-pressure state to a high-temperature and high-pressure state under the action of the compressor, and then dissipate the heat of the refrigerant to the surrounding environment through the condenser, thereby reducing the temperature of the refrigerant . Then, the refrigerant passes through the expansion valve to reduce the temperature and pressure, and then enters the evaporator, thereby absorbing the heat in the surrounding environment and raising the temperature of the refrigerant. Finally, the refrigerant enters the compressor again and circulates repeatedly, so as to achieve the purpose of refrigeration.

Advantages of air cooled process chillers

Compared with water-cooled chillers, air cooled process chillers have the following advantages

1. Easy installation: The air-cooled chiller does not require an additional water-cooling system, and only needs a well-ventilated space to install.

2. Simple maintenance: Air-cooled chillers do not require additional water pumps and water pipes, and are relatively simple to maintain.

3. Energy saving and environmental protection: The air-cooled chiller does not require additional water pumps and water pipes, which saves water resources and also reduces the energy consumption of water pumps.

4. Wide range of application: The air-cooled chiller is suitable for various environments, whether it is industrial, commercial or household.

Application of air cooled process chillers

Air-cooled chillers are widely used in various fields, including industrial, commercial and household, etc. Among them, the industrial field is mainly used in pharmaceutical, chemical, electronics, food and other industries; the commercial field is mainly used in supermarkets, hotels, restaurants and other places; the family field is mainly used in home appliances such as home air conditioners and refrigerators.
