Embodiment Construction

[0028] Air conditioning systems include general residential cooling air conditioners for cooling only, heating air conditioners for heating only, heat pump air conditioners for both cooling and heating, and multi-unit air conditioners for cooling and heating multiple indoor spaces . Next, a heat pump type air conditioner (hereinafter referred to as "air conditioner") as an example of an air conditioning system will be described in detail.

[0029] figure 1 is a view showing the configuration of the air conditioner 100 according to the embodiment of the present invention. figure 2 It is a block diagram showing a control flow of the air conditioner 100 .

[0030] refer to figure 1 and 2 , the air conditioner 100 includes a compressor 110 , an indoor heat exchanger 120 , an outdoor heat exchanger 130 , a first expansion valve 141 , a second expansion valve 142 , a phase separator 150 and a four-way valve 160 . The indoor heat exchanger 120 functions as an evaporator in cool...

Abstract

An air conditioning system 100 can improve the cooling / heating performance of the system because the injection of refrigerant into a compressor 110 is achieved. The air conditioning system can further improve the cooling / heating performance in a low temperature region by injecting the refrigerant as a two-phase refrigerant or a superheated vapor state into the compressor. The air conditioning system can prevent damage of the compressor and further improve reliability by controlling such that the ratio of a liquid refrigerant in the refrigerant injected into the compressor may be less than a set value.

Description

technical field [0001] The present invention relates to an air conditioning system, and more particularly, to an air conditioning system capable of improving the performance and stability of the system by controlling such that a ratio of liquid refrigerant in refrigerant injected into a compressor is smaller than a predetermined value. Background technique [0002] In general, an air conditioning system is an apparatus for cooling or heating an indoor space by compressing, condensing, expanding, and evaporating a refrigerant. [0003] Air conditioning systems are classified into a conventional air conditioner including an outdoor unit and an indoor unit connected to the outdoor unit and a multi-type air conditioner including an outdoor unit and a plurality of indoor units connected to the outdoor unit. Also, air conditioning systems are classified into cooling air conditioners that supply only cooled air to indoor spaces by driving refrigerant circulation in only one directi...
