Features of the Company series screw brine unit is the system design is simple and stable, energy efficient operation. This feature is reflected in the heat exchanger of the latest technology and advanced use of semi-hermetic twin-screw compressor combined with microcomputer control technology: 1. Screw brine refrigeration unit is widely used in various fields of industrial refrigeration plant, to meet the needs of a variety of different processes. 2. Screw brine unit with R22 refrigerant refrigeration equipment maintenance, providing low temperature below 0 ℃ cold source used refrigeration equipment, the water temperature can reach -40 ℃. 3. brass condenser fouling and more small diameter refrigeration equipment, poor heat dissipation. Solution: Clean the condenser brass. 4. Too many refrigerant. Solution: excess refrigerant emissions. 5. The expansion valve opening is too large. Solution: appropriate to reduce the expansion valve opening degree, the compressor protection thermal relay valves (RESTET) pressed to identify the reasons used refrigeration equipment _ Snow Dragon refrigeration (certified) _ refrigeration equipment by the Dongguan City-long Refrigeration Electrical and Mechanical Equipment Engineering Co.
