<P>PROBLEM TO BE SOLVED: To provide a hot water supply outdoor unit suppressed in a possibility of the entry of drainage into the hot water supply outdoor unit along a drain plug during the draining of a water circuit, having the excellent efficiency of draining work and easily identifying a water leakage failure in the water circuit. <P>SOLUTION: The hot water supply outdoor unit includes: a refrigerant circuit having at least a compressor for compressing a refrigerant and a heat exchanger for performing heat exchange between the refrigerant and water; and the water circuit where water is circulated. The refrigerant circuit and the water circuit are stored in a casing. The hot water supply outdoor unit further includes: the drain plug 20 fixed outside the casing and connected to the water circuit to drain water in the water circuit; and a water draining projection 20a formed in the drain plug 20 and draining water the outside of the casing to prevent the entry of the water into the casing during draining of water. <P>COPYRIGHT: (C)2010,JPO&INPIT |
