BLOWN AIR TEMPERATURE CONTROL METHOD FOR AIRRCONDITIONER FOR ELECTRIC COMPUTER ROOM

摘要

PURPOSE:To omit the large-scale air reheater to reheat the sucked air out of the evaporator by providing the auxiliary condenser refrigerant path of different system from the refrigerant main pipeline at part of the evaporator and then controlling the heat exchange amount between the evaporator and the air. CONSTITUTION:The refrigerant path of auxilary condenser 11 which is of the different system from the refrigerant main pipeline is provided at part of evaporator 4. This refrigerant path is constituted with the pipelines branched off from blowing pipeline branching point 17 of compressor 1 and refrigerant flow-out pipeline branching point 20 of condenser 2. Both the gas refrigerant blown off from compressor 1 and the liquid refrigerant after passing through condenser 2 are circulated properly to the refrigerant path of condenser 11 via electromagnetic valve 22 which operates through sensing the temperature within the electronic computer room. Thus, the temperature is controlled to the proper level for the blown air circulating evaporator 4. In this way, the large-scale air reheater which reheats up the sucked air can be omitted from evaporator 4.
