Provided is a hot water supply tank including: a case forming an appearance of the hot water supply tank; a heating container accommodating a fluid and having an inner side treated with anticorrosive; a heater installed on an outer side of the heating container and transferring heat to the fluid; and a heat insulator interposed between the case and the heater, wherein in a predetermined volume of the heating container, a ratio at which a performance of the heater to transfer heat (hereinafter, heat transfer performance) is maximized (hereinafter, optimum ratio) among the ratios of side height to bottom diameter of the heating container (hereinafter, aspect ratios) is determined by whether the heater is installed on the bottom as well as side of the heating container, and determined based on an area of the heating container occupied by the heater (hereinafter, heat transfer area).

Hot water supply tank

A heat radiation unit is disclosed. The heat radiation unit includes a heat radiation member thermally connected to a heat source, to radiate heat generated from the heat source, a refrigerant pipe thermally connected to the heat radiation member while being formed therein with a channel, through which refrigerant flows, a pipe jacket coupled to the heat radiation member, and formed with a receiving groove to receive a portion of the refrigerant pipe, and a cover bracket to press the portion of the refrigerant pipe received in the receiving groove of the pipe jacket in a downward direction of the receiving groove. An outdoor unit of an air conditioner is also disclosed. The outdoor unit includes a case to form an appearance of the outdoor unit, a heat source disposed in the case, and the heat radiation unit connected to the heat source, to radiate heat from the heat source.

Heat radiation unit and outdoor unit of air conditioner having the same

An outdoor heat exchanger includes a passage of a refrigerant that has a length varied depending on an operational mode. The outdoor heat exchanger is included in an air conditioner and configured to operate as a condenser in a cooling operation of the air conditioner and as an evaporator in a heating operation of the air conditioner. The outdoor heat exchanger includes a plurality of plates, a plurality of first refrigerant tubes, a plurality of second refrigerant tubes, and a plurality of third refrigerant tubes. In the cooling operation, a condensed refrigerant flows in the plurality of first refrigerant tubes, the plurality of second refrigerant tubes, and the plurality of third refrigerant tubes. In the heating operation, an evaporated refrigerant flows in the plurality of first refrigerant tubes and the plurality of third refrigerant tubes, but does not flow in the plurality of second refrigerant tubes.

Outdoor heat exchanger and air conditioner comprising the same

An air conditioner that includes a compressor that compresses a refrigerant, a main outdoor heat exchanger that condenses the refrigerant in a cooling mode and that evaporates the refrigerant in a heating mode, an indoor heat exchanger that evaporates the refrigerant in the cooling mode while condensing the refrigerant in the heating mode, a switch that guides the refrigerant discharged from the compressor to the main outdoor heat exchanger in the cooling mode and that guides the refrigerant discharged from the compressor to the indoor heat exchanger in the heating mode, and a sub outdoor heat exchanger that evaporates a portion of the refrigerant condensed in the main outdoor heat exchanger in a low-load cooling mode and that condenses a portion of the refrigerant discharged from the compressor in a low-load heating mode.
