SENSIBLE HEAT COOLING THERMO-HYGROSTAT AND THEREOF OPERATION METHOD

摘要

A sensible heat cooling thermo-hygrostat and an operation method thereof are provided to save the initial investment by reducing the manufacturing cost and to retrieve the equipment investment in a short time. A sensible heat cooling thermo-hygrostat comprises compressors(COM-1,2) and an oil separator(OS). The oil separator separates freezer oil from hot gas refrigerant supplied from the compressors to partially send the freezer oil to the compressors. A blowing fan(PF) is installed at an outdoor unit to cool the hot gas refrigerant supplied from the oil separator. Condensers(CON-1,2) condense refrigerant gas. A receiver(RCT) stores liquid-refrigerant having passed through the blowing fan. First and second outdoor units are connected with an outlet of the receiver to supply the liquid-refrigerant to an indoor unit. A filter driver(FD) removes moisture and impurities from the refrigerant.
