Abstract:
1. A heat-pump-type water heater comprising: a heat source unit including: a compressor, a pressure reducing mechanism, and a heat-source-side heat exchanger, all of which compose one section of a heat-pump-type refrigeration cycle; and a first controller which controls operations of an outdoor blower and electric devices; a hydrothermal exchange unit disposed apart from the heat source unit, connected to the heat source unit by means of refrigerant pipes and electric wiring, and including: a water heat exchanger composing part of the other section of the heat-pump-type refrigeration cycle and serving as a use side heat exchanger; a pump which guides water via a water pipe to the water heat exchanger; and a second controller which controls the operation of the pump; and a tank unit connected to the hydrothermal exchange unit via water pipes and including a tank which stores hot water obtained as a result of heat exchange by the water heat exchanger, wherein the hydrothermal exchange unit has a housing, the front, rear, top, left and right sides of the housing being covered with panels and a bottom plate for the housing being disposed a predetermined distance above lower ends of the panels, and the housing has an internal space that accommodates the water heat exchanger, the pump, the water pipes, the refrigerant pipes, and the second controller, and an external space below the bottom plate of the housing that accommodates connectors for the water pipes and refrigerant pipes, the bottom side of the external space being open to a room outside of the housing in which the hydrothermal exchange unit is disposed, and the front side of the external space being provided with a pipe cover having a height sized in accordance with the vertical extent of the connectors for the water pipes and refrigerant pipes, and wherein the second controller is removably attached in a front portion of the internal space of the housing, and adjacent to the front side of the housing, so that the second controller is easily accessed by the removal of the front side, and the water pipes and the refrigerant pipes are readily accessible when the second controller is removed from the housing.
