Abstract

The present invention relates to an air conditioning system capable of preventing that a liquid refrigerant is included in a refrigerant injected into a compressor. Accordingly, the risk of liquid compression of the compressor is greatly reduced, thereby decreasing the possibility of damage to the compressor and improving reliability and performance.

Description

technical field [0001] The present invention relates to an air conditioning system, and more particularly, to an air conditioning system capable of judging whether liquid refrigerant is contained in refrigerant injected from a compressor and preventing liquid compression in the compressor. 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-connected air conditioner including an outdoor unit and a plurality of indoor units connected to the outdoor unit. Also, the air conditioning system is divided into a refrigeration air conditioner for supplying only cooling air to an indoor space by driving refrigerant circulation in only one direction and a cooling air conditione...
