What are the main components of Dalian water-cooled screw chiller?
Dalian water-cooled screw chiller is a common refrigeration equipment used to provide cooling water or coolant to reduce temperature. It uses a screw compressor as the main compression element to achieve refrigeration effects through compression and condensation cycles.
The main components of Dalian water-cooled screw chiller include:
1. Screw compressor: The screw compressor is the core component of a water-cooled screw chiller, which compresses the refrigerant through the rotation of the screw and provides cooling effect.
2. condenser: The condenser is the part that releases heat from the compressed refrigerant and cools it into a liquid state through water cooling or cooling towers.
3. Expansion valve: The expansion valve controls the flow rate of refrigerant, causing it to evaporate in the evaporator, absorb heat, and lower the temperature.
4. Evaporator: The evaporator is a part of the refrigeration cycle that reduces the temperature of water or liquid by absorbing heat and evaporating refrigerant.
5. Control system: The control system is used to monitor and control the operating status of the water-cooled screw chiller, including the monitoring and adjustment of parameters such as temperature, pressure, flow rate, etc.
The working principle of a water-cooled screw chiller is that the refrigerant is compressed into high-temperature and high-pressure gas in the screw compressor, and then dissipated through the condenser to become a high-pressure liquid. The high-pressure liquid is controlled by the expansion valve to flow rate and enters the evaporator. During the heat absorption process, it evaporates and lowers the temperature. Cooling water or coolant exchanges heat with refrigerant through an evaporator, absorbs heat, lowers the temperature of the water or liquid, and is then recycled.
