JLSF-80D Air Cooled Screw Chiller Plastic Processing, Metal Processing, Chemical Industry
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:
Features of the air-cooled screw chiller include:
1.No additional cooling water system: Compared with water-cooled chillers, air-cooled screw chillers do not require additional cooling water systems, so they are simpler and cost-effective.
2.Wide range of applications: Air-cooled screw chillers are suitable for various types of buildings and places, such as commercial office buildings, hotels, hospitals, schools, etc.
3.High refrigeration efficiency: The air-cooled screw chiller uses a screw compressor, which has the advantages of high refrigeration efficiency, low noise, and low maintenance cost.
4.Easy installation: The installation of the air-cooled screw chiller is relatively simple and does not require additional equipment such as water pipes and water pumps.
5.High reliability: The air-cooled screw chiller is designed and manufactured with high precision, and has good stability and reliability.
6.Strong adaptability: The air-cooled screw chiller has strong adaptability and can adapt to different environmental conditions and load changes.
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.

What should I do if the air-cooled screw chiller fails?
If the air-cooled screw chiller fails, it needs to be dealt with in time to avoid the expansion of the failure and affect the normal operation of the equipment. The following are some common faults and their solutions:
1.Poor or non-working cooling: A component such as the condenser, cooling tower, or water pump may be faulty and need to be checked and repaired.
2.The compressor is noisy: it may be that the impeller or bearing of the compressor is damaged, and the impeller or bearing needs to be replaced.
3.Insufficient cooling water flow: It may be that the water pump is damaged or the pipe is blocked, and these parts need to be checked and repaired.
4.High pressure protection or low pressure protection: It may be that components such as compressors, condensers or cooling towers have failed, and these components need to be checked and repaired, and the settings of the pressure controller need to be adjusted at the same time.
5.Electrical failure: It may be a failure of the motor, controller or sensor, etc., and these electrical components need to be checked and repaired.
For the above faults, if you cannot handle them by yourself, it is recommended to seek professional maintenance personnel or technical support from the equipment manufacturer, so as to solve the problems in time. At the same time, in order to avoid the occurrence of failures, it is also necessary to maintain the equipment regularly, discover and deal with potential failures in time, so as to ensure the normal operation of the equipment and prolong its service life.
