A heat exchanger and an air conditioner including the same. The heat exchanger includes a plurality of heat transfer tubes formed in a flat shape and configured to allow a refrigerant to flow in a vertical direction therein. The heat transfer tube includes a gas refrigerant region including one end connected to a refrigerant inlet port and another end disposed above the refrigerant inlet port; a two-phase refrigerant region including one end connected to the other end of the gas refrigerant region and another end disposed below a refrigerant outlet port; and a liquid refrigerant region including one end connected to the other end of the two-phase refrigerant region and another end connected to the refrigerant outlet port.

Heat exchanger and air conditioner having the same

A refrigerant charging device and a refrigerant charging system include a refrigerant charging flour path having a refrigerant charging port connected to a refrigerant flow path of an air conditioner, a valve provided at the refrigerant charging flow path, and a control device configured to control the valve. The control device includes a discharging superheat calculator configured to calculate the discharging superheat degree from a refrigerant temperature and a refrigerant pressure at a discharge side of a compressor, and a valve controller configured to control the opening and closing state of the valve based on the calculated discharging superheat degree calculated by the discharge super-heat calculator.

Refrigerant charge device and refrigerant charge system having the same

An air conditioner includes a heat storage apparatus for storing heat emitted from a compressor arranged in an outdoor unit, wherein the heat storage apparatus includes a heat storage tank installed in the compressor for storing heat emitted from the compressor and a heat transfer member configured to deliver heat emitted from the compressor to the heat storage tank, wherein the heat storage tank includes a first heat transfer face configured to have a form corresponding to a part of an outer circumferential face of the compressor to come into contact with the outer circumferential face of the compressor and a pair of second heat transfer faces configured to extend from both ends of the first heat transfer face to be in parallel to each other and form space with the outer circumferential face of the compressor, and wherein the heat transfer member is arranged in the space.
