Problems solved by technology

Here, an excessive pressure difference between the low side and the high side negatively affects the reliability of the compressor
[0006] Furthermore, in heating mode in conditions of extremely low outdoor temperatures, the compressor has a very high temperature in order to have maximum capacity, which negatively affects the reliability of the compressor

Embodiment Construction

[0014] Now, preferred embodiments of the present invention will be explained with reference to the drawings.

[0015] Such as figure 1 As shown, the air conditioning system for heating and cooling air according to the present invention includes: a screw compressor 10 for compressing refrigerant in a liquid state to a high temperature and high pressure state; for heating the circulating refrigerant with outdoor air Exchange outdoor heat exchanger 11; indoor heat exchanger 12 for heat exchange between the circulating refrigerant and indoor air; four-way valve 13 for switching the refrigerant route so that the refrigerant compressed by the compressor 11 Optionally flows into the outdoor heat exchanger 11 or the indoor heat exchanger 12. The four-way valve 13 includes four outlets connected to the compressor 10 through a refrigerant pipe 14, connected to the outdoor heat exchanger 11 through a refrigerant pipe 15, connected to the indoor heat exchanger 12 through a refrigerant pipe 16...

Abstract

An air conditioning system with a compressor for compressing refrigerant, an outdoor heat exchanger for exchanging heat between the refrigerant and outdoor air, an indoor heat exchanger for exchanging heat between the refrigerant and indoor air, for converting Four-way valve for the direction of refrigerant flow, a refrigeration expansion device installed in the refrigerant pipe connecting the outdoor heat exchanger and the indoor heat exchanger, installed in the refrigerant pipe connecting the refrigeration expansion device and the indoor heat exchanger The vapor-liquid separator comprises: a liquid refrigerant supply pipe, which connects the vapor-liquid separator and the inlet of the compressor, and is used to supply the liquid refrigerant in the vapor-liquid separator to the inlet of the compressor; and the liquid refrigerant supply A valve for controlling the supply of liquid refrigerant through the liquid refrigerant supply pipe. The air conditioning system has improved heating performance, and in a heating mode under an extremely low outdoor temperature condition, reduces a compression ratio and a discharge temperature of a compressor, thereby improving reliability of the compressor.

Description

Technical field [0001] The present invention relates to an air conditioning system for heating or cooling air, and in particular, to such an air conditioning system for heating or cooling air: when the outdoor temperature is low, it has an improved capacity in the heating mode, And reduce the compression ratio and discharge temperature of the compressor, thereby increasing the reliability of the compressor. Background technique [0002] Generally, an air conditioning system optionally operating in heating or cooling mode includes a compressor, an outdoor heat exchanger, a refrigerant expansion device, an indoor heat exchanger, and a four-way valve. When the air conditioning system is in the cooling mode, the refrigerant discharged from the compressor is supplied to the outdoor heat exchanger, and the refrigerant route is switched by the four-way valve, thereby introducing the refrigerant passing through the indoor heat exchanger into the inlet of the compressor. Correspondingly, ...
