Product Description:

Air-cooled screw chiller is a kind of industrial refrigeration and commercial air conditioning equipment, mainly composed of evaporator, compressor, condenser and expansion valve and other components. It uses a screw compressor to compress the low-temperature and low-pressure refrigerant into a high-temperature and high-pressure gas, then releases heat to the outside through the condenser, and finally reduces the temperature and pressure of the refrigerant through the expansion valve to return to the evaporator for recycling.

During operation, the air-cooled screw chiller absorbs the heat in the outdoor air, cools the cooling water and circulates it to the room, so as to reduce the indoor temperature. Its cooling efficiency is greatly affected by factors such as outdoor temperature and humidity, so its effect may be limited in high-temperature and high-humidity environments.

Compared with water-cooled chillers, air-cooled screw chillers do not require an additional cooling water system, so they are simpler and more cost-effective. However, since it uses outside air for cooling, it can be problematic in areas with high air pollution or where indoor air quality needs to be maintained.

Production Features:

Air-cooled screw chillers and water-cooled screw chillers are two different cooling methods, and they have some different characteristics:

1. Cooling method: The air-cooled screw chiller dissipates heat to the surrounding air through the built-in fan and heat sink to achieve cooling. Water-cooled screw chillers absorb heat by circulating water and release the heat to the atmosphere through cooling towers or cooling equipment.

2. Installation and maintenance: Air-cooled screw chillers do not need to connect water pipes and cooling towers, and installation and maintenance are relatively simple. The water-cooled screw chiller needs to be connected with water pipes and cooling towers, and the water circulation system needs to be checked and maintained regularly.

3. Cooling efficiency: Water-cooled screw chillers generally have higher cooling efficiency because water conducts heat better than air. Under high temperature environment or high load operating conditions, water-cooled screw chillers can usually provide more stable and reliable cooling effect.

4. Space requirements: The air-cooled screw chiller does not require a cooling tower and occupies a relatively small space. The water-cooled screw chiller requires an additional cooling tower to release heat, which occupies a relatively large space.

5. Environmental adaptability: Air-cooled screw chiller is suitable for environments without stable water supply or poor water quality, because it does not depend on external water sources. The water-cooled screw chiller requires a stable water source and has higher requirements for water quality.

To sum up, the air-cooled screw chiller has the advantages of easy installation, no need for water source and cooling tower, and suitable for some special environments. While the water-cooled screw chiller has high cooling efficiency and stability, it is suitable for general industrial and commercial applications, but requires an additional water circulation system and cooling tower. Which cooling method to choose should be decided according to specific needs and environmental conditions.

Working Principle:

The working principle of the air-cooled screw chiller is as follows:

Compression process: The refrigerant is compressed into a high-temperature and high-pressure gas in the screw compressor, and then enters the condenser.

Condensation process: The high-temperature and high-pressure gas is cooled in the condenser to become a high-pressure liquid, and at the same time release heat, which is dissipated into the outdoor air through fans and radiators.

Expansion process: After the high-pressure liquid is decompressed by the expansion valve, it becomes a low-temperature and low-pressure liquid, and then enters the evaporator.

Evaporation process: The low-temperature and low-pressure liquid evaporates in the evaporator, absorbs the heat in the room, cools down the cooling water in the room, and circulates it to the room, thereby achieving the purpose of reducing the indoor temperature.

Application Industry:

The air-cooled screw chiller is a chiller that uses a screw compressor and an air-cooled condenser, and is suitable for the following industries:

1.Industrial manufacturing: In the industrial manufacturing process, many equipment need to be cooled, such as plastic processing equipment, metal processing equipment, chemical equipment, etc. At this time, it is necessary to use air-cooled screw chillers to provide cooling services for these equipment.

2.Commercial buildings: Air-cooled screw chillers can provide refrigeration services for large commercial buildings, factories and public places, such as shopping centers, supermarkets, hotels, hospitals, office buildings, etc.

3.Pharmaceutical industry: In the pharmaceutical industry, many production processes need to control temperature and humidity to ensure product quality and safety, so chillers are needed for cooling and humidity control.

4.Food industry: In the food industry, many production processes require temperature control, such as wine, beverages, dairy products, etc., and chillers are required for refrigeration.

5.Electronics industry: In the electronics industry, many devices need to be cooled, such as electronic components, semiconductor equipment, etc., and chillers are required for cooling.

In short, air-cooled screw chillers are suitable for various industries and occasions that require refrigeration, such as industrial manufacturing, commercial construction, pharmaceutical industry, food industry, electronics industry, etc.
