冷冻主机2(国外英文资料) There are two types of chiller: water-cooled and air-cooled. The cooling effect of water cooling is better, but it needs cooling water, the air cooling type is flexible and convenient, and no cooling water is needed. It is suitable for water shortage or mobile occasions. Industrial refrigerator The working medium is the refrigerator refrigeration system undertakes the refrigerant heat transfer task, commonly used are: refrigerant freon, ammonia, lithium bromide, methyl chloride, freon which according to the gasification temperature and chemical formula of different fluoride in 11 (R-11), 12 (R-12), fluoride fluoride, fluoride (R-13) 13 21 (R-21), 22 (R-22), fluorine fluorine 113 (R-113), 114 (R-114), fluoride fluoride (R-142) and other 142. The refrigerant can be used in low pressure (condensing pressure less than 0.3-0.3MPa) high temperature (evaporation temperature greater than 0 DEG C), pressure (condensing pressure 1-2MPa) temperature (evaporation temperature 0 -50 DEG C) and high pressure (condensing pressure greater than 2MPa) and low temperature (evaporation temperature is less than -50 DEG C) refrigeration system. Equipment： 1, compressor: Panasonic, Daikin, wheel, Pitzer and other compressors, ultra high energy efficiency, low noise, safe and reliable; 2, pump: LG, source and FFC large flow chiller vortex pump, does not block the starting torque; 3 、 computer PC board, touch control, safe and convenient; 4 、 temperature controller: import liquid crystal display temperature control electronic board; 5, the United States imports ALCO expansion valve, filter; 6 、 304 stainless steel water tank with 1 heat insulation material inside and outside; 7, South Korea LG electrical appliances; 8 、 safety protection system Compressor delay starting pump overload protection and indicator lamp compressor overload protection of motor protection and reverse lights compressor overload protection refrigerant shortage protecting and indicating lamp refrigerant pr
