Abstract

A dual turbo centrifugal chiller includes: first and second evaporators connected in series or in parallel; first and second condensers connected in series or in parallel; and first and second compressors including impellers, wherein cold water passes through the second evaporator after passing through the first evaporator, and cooling water passes through the second condenser after passing through the first condenser, the first compressor containing a refrigerant connects the first condenser to the second evaporator, and the second compressor containing a refrigerant connects the second condenser to the first evaporator, and the impellers of the first compressor and second compressor are rotated simultaneously using a single driving unit. The invention can increase the efficiency of compression system and the efficiency of the whole refrigerator; and applying the invention can realize the bearing design without paying attention to thrust applied to a special direction.

Description

technical field [0001] The present invention relates to a dual turbo centrifugal chiller, in particular to configurations to reduce the temperature difference (head) of the compressors in components of two separate chillers, reduce the size of the chiller and A twin-turbo centrifugal freezer with increased efficiency. Background technique [0002] A general refrigerator includes a compressor, an evaporator, a condenser, and a safety valve, and circulates a refrigerant to transfer heat from the evaporator to the condenser through heat exchange. [0003] 1 is a schematic diagram showing a general refrigerator 10 . [0004] Such as figure 1 As shown, refrigerator 10 includes an evaporator 30 , a condenser 20 and a compressor 40 . The cold water 31 flows through the evaporator 30 and the cooling water 21 flows through the condenser 20 . [0005] The refrigerant 51 , 52 circulates in the compressor 40 which connects the evaporator 30 to the condenser 20 . The refrigerant 51 ...
