Freezer refrigerator compressor means changing the refrigerant gas pressure changes to achieve low temperature refrigeration equipment. The use of a compressor, its use and compress different working medium, it is different from the air compressor. Press the difference freezer on the structure and working principle, similar to the air compressor can be divided into several different forms piston, screw, centrifugal and so on. Freezer refrigeration equipment is one of the most important components of compression. Introduction freezer has a water-cooled, air-cooled two. Water-cooled chiller is better, but need cooling water, air-cooled flexible, without cooling water, suitable for dry areas or need to move occasions. Industrial freezer refrigerator refrigeration system working medium is charged with the task of transferring heat refrigerant, common refrigerants are: Freon, ammonia, lithium bromide, chloride, etc., wherein its vaporization temperature Freon and chemical formula There are differences in pressure (condensing pressure) medium temperature (evaporation temperature 0--50 ℃) and high pressure (condensing pressure is greater than 2MPa) low temperature (evaporation temperature of less than -50 ℃) cooling system. Features: 1, Compressor: Panasonic, Daikin, Copeland, Bitzer compressor and other ultra-high energy efficiency, low noise, safe and reliable; 2, pump: LG, Source of legislation, FFC high flow freezer for vortex pump , do not plug the starting torque; 3, the computer PC board, touch control, safe and convenient; 4, Thermostat: electronic temperature control imports LCD panels; 5, the United States imports ALCO expansion valve, filter; 6, built overcoat 304 stainless steel water tank insulation material 1; 7, South Korean LG Electronics; 8. security system compressor delay start overload protection ice water pump motor and compressor overload indicator reversal protection and compressor overload protection and indicator lights Refrigerant insufficient protective lamp refrigerant pressure relief valve cooling bad protective lamp failure alarm buzzer.
