SYSTEMS AND METHODS FOR A REFRIGERANT SUB-SYSTEM FOR A HEATING, VENTILATION, AND AIR CONDITIONING SYSTEM

A refrigerant sub-system includes a compressor, a condenser, an expansion valve, an evaporator, and a refrigerant-air heat exchanger. The compressor receives and compresses refrigerant. The condenser condenses the refrigerant and transfers heat from the refrigerant to a first fluid. The expansion va...

Zusammenfassung:	A refrigerant sub-system includes a compressor, a condenser, an expansion valve, an evaporator, and a refrigerant-air heat exchanger. The compressor receives and compresses refrigerant. The condenser condenses the refrigerant and transfers heat from the refrigerant to a first fluid. The expansion valve expands the refrigerant. The evaporator vaporizes the refrigerant at the first pressure and transfers heat from a second fluid to the refrigerant. The refrigerant-air heat exchanger has a first operating mode and a second operating mode. In the first operating mode, the condenser is adapted to condense a first portion of the refrigerant from a vapor to a liquid, and the refrigerant-air heat exchanger is adapted to condense a second portion of the refrigerant from a vapor to a liquid and transfer heat from the second portion of the refrigerant to air.
