<P>PROBLEM TO BE SOLVED: To save on a space for a heat source machine while suppressing degradation of heat exchanging performances of an evaporator and a radiator in a heat pump water heater. <P>SOLUTION: This heat pump water heater has: the evaporator composed of fin tube heat exchangers of two rows disposed on a base; a radiator storage box disposed in a lower section at a leeward side of the evaporator and receiving the radiator inside; and a fan disposed on a top face of the radiator storage box and distributing the outside air to the evaporator. As a row pitch of the fin tube heat exchanger of the row at the leeward side of the evaporator is smaller than that of the fin tube heat exchanger of the row at a windward side, the space of the heat source machine is saved on while suppressing the degradation of heat exchanging performances of the evaporator and the radiator. <P>COPYRIGHT: (C)2009,JPO&INPIT |
