HYBRID REFRIGERANT CIRCULATING COOLING SYSTEM

摘要

A hybrid refrigerant circulating cooling system comprising: a refrigerant conduit in which refrigerant is disposed; an air conditioner terminal device (11) adjacent to an object (2) to be cooled and comprises a heat exchanger (1110) and a blower (1120), wherein the heat exchanger communicates with the refrigerant conduit to form a circuit, and refrigerant flows into the heat exchanger in a liquid phase and flows out of the heat exchanger in a gas-liquid two- phase or in a gas phase, and the blower conveys a working air stream which sequentially contacts with the object to be cooled and the heat exchanger; a cooling device downstream of the heat exchanger along the direction in which refrigerant flows, wherein refrigerant in the refrigerant conduit downstream of the cooling device is in a liquid phase; and a pumping device downstream of the cooling device in order to pump refrigerant in a liquid phase into the heat exchanger.
