industrial Chiller operating conditions and technical parameters


Refrigeration operating conditions of chillers: Generally expressed by the temperature of the inlet and outlet water of cooling water and chilled water. The standard cooling operation conditions of the chiller are usually: the chilled water inlet and outlet water temperature is 12/7 ° C, and the cooling water inlet and outlet water temperature is 32/37 ° C. Some imported chiller units may change.   Other technical parameters of the chiller, such as cooling capacity: the full amount of cold output of the chiller operating under standard conditions is the main technical indicator for measuring the capacity of the chiller.   Refrigerant used in chillers: usually R22, R123, R134a, etc. At present, the R22 substitutes are higher in the international voice: AZ20 (No. R410A or R410B) of the United Signal Corporation of the United States; SUVA9000 of DuPont's non-azeotropic mixture and the non-azeotropic mixture KIea66 of the British ICI Company. (No. R407C); non-azeotropic mixture HFC32/HFC134a of Japan Daikin.   The cooling capacity adjustment range of the chiller: generally expressed as a percentage of the cooling capacity in the standard working condition.   Chiller input power: Compressed refers to the compressor electrode power; absorption refers to the sum of the electrode powers of various pumps in the machine.   Water head pressure loss of chiller: refers to the resistance of cooling water and cold water flowing through the condenser and evaporator
