30D Air Cooled Screw Chiller Plastic Cooling Forming, Printing Plate Cooling, Low Temperature
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:
The screw chiller has the following characteristics:
1.High efficiency and energy saving: The screw compressor has high compression efficiency, can provide high cooling capacity with low power consumption, and reduce energy consumption.
2.Stable and reliable: The screw compressor has compact structure, stable operation, low noise and vibration, and does not require additional foundation support. The installation and maintenance are relatively simple, so the reliability is high.
3.Control system: The control system of the screw chiller can realize the automatic control and protection functions of the equipment, and has the characteristics of a high degree of intelligence.
4.Wide range of applications: screw chillers are suitable for various industries with strict refrigeration requirements, such as electronics, chemical industry, medicine, food and other fields, and have broad application prospects.
In conclusion, the screw chiller is an energy-efficient, stable and reliable refrigeration equipment for various industrial and commercial applications.
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.
