摘要： An air conditioner according to an embodiment includes: a compressor configured to compress a refrigerant; an indoor heat exchanger configured to convert a vapor refrigerant into a liquid refrigerant in a heating mode; an outdoor heat exchanger configured to convert a liquid refrigerant into a vapor refrigerant in the heating mode; a main pipe connecting the indoor heat exchanger to the outdoor heat exchanger; an injection pipe branching from the main pipe and connecting to an injection port of the compressor; an injection valve installed on the injection pipe and configured to control a flux of the refrigerant flowing to the injection pipe; and a controller configured to calculate a target discharge superheat (DSH) based on a correlation between a compression coefficient, a compressor frequency, and a DSH that are represented by an operating condition , and control a current DSH based on the target DSH.

摘要： Disclosed is an air conditioner with a compressor fixation structure having improved product reliability due to strengthened hardness of a boss. The air conditioner includes a compressor for compressing a refrigerant, a base for supporting the compressor, a compressor support coupled to the base to support the compressor; at least one boss protruding from the base, a vibration absorption member for absorbing vibration generated by the compressor, and a fastening member, wherein the fastening member is inserted into the boss and the vibration absorption member, and at least a portion of the fastening member protrudes below a bottom surface of the base.
