Air-cooled screw machine
The air-cooled screw unit is composed of air as the cold and heat source, water as the cold and hot medium, including compressor, evaporator, condenser, refrigeration accessories, electronic control system, etc. Due to the use of finned condenser to exchange heat with air, it is called air-cooled type. The air-cooled screw machine unit has the advantages of high efficiency, low noise, reasonable structure, simple operation, safe operation, and convenient installation and maintenance.
Suitable for public facilities such as hotels, shopping malls, office buildings, exhibition halls, airports, sports centers, etc., and able to meet the different usage requirements of temperature control systems in industries such as electronics, pharmaceuticals, biology, textiles, chemicals, metallurgy, electricity, and machinery.
Process Introduction
Working principle of air-cooled screw unit: The refrigerant is compressed to the condenser through a spiral compressor. The high-pressure refrigerant is condensed in the condenser, and then the water and impurities in the refrigerant are filtered out through a filter. The refrigerant is then placed in a low-pressure and low-temperature state through an expansion valve and enters the evaporator for cooling. After cooling, the refrigerant enters the compressor again to continue the next cycle.
The main control system of the device uses Huceen E7-200 Smart PLC, which communicates with the touch screen through the built-in Ethernet port. The digital input point signals of the CPU are used to monitor the status of the compressor, cooling fan, water pump, water flow switch, etc. The built-in digital output points are used to control the compressor, valve, water pump, and cooling fan respectively; Expanding the analog input module to detect the temperature of water in the pipeline of the unit; Analog output is used to regulate the frequency of the two external water pumps of the unit.
