SYSTEMS AND METHODS FOR COMPUTER ROOM AIR CONDITIONING

摘要

A cooling system includes a condenser and first and second cooling circuits. The condenser is configured to condense refrigerant to a liquid. The first cooling circuit includes a direct expansion valve coupled to the condenser, a first evaporator coil coupled to the direct expansion valve, and a compressor coupled to the first evaporator coil. The first cooling circuit receives at least a first portion of the liquid refrigerant and output first refrigerant vapor, and the compressor receives the first refrigerant vapor and output a compressor refrigerant output to the condenser. The second cooling circuit includes a pump coupled to the condenser, an economizer valve coupled to the pump, and a second evaporator coil coupled to the economizer valve. The second cooling circuit receives at least a second portion of the liquid refrigerant and output a second vapor refrigerant to the condenser.
