Claims

[Scope of utility model registration request]

(1) A refrigeration circuit in which a compressor, a condenser for heat exchange with water, an expansion valve, an evaporator for collecting solar heat and outside air are connected in a ring to circulate a refrigerant, a hot water storage tank, and the condenser are combined. In a solar heat pump water heater that is thermally coupled to a heat exchanger and a hot water circulation circuit that connects a circulation pump in an annular manner and circulates water, the above condenser and condenser are combined.
The heat exchanger is divided into a series structure combination of a first condenser and a second condenser, a first heat exchanger and a second heat exchanger, and the first heat exchanger and the first heat exchanger of the hot water circulation circuit are combined. A solar heat pump water heater characterized in that a bypass circuit from the middle of the second heat exchanger to the hot water storage tank is branched from the hot water circulation circuit.

(2) The solar heat pump water heater according to claim 1, wherein a flow rate regulating valve is provided in the bypass circuit of the hot water circulation circuit.

(3) The above utility model registration characterized in that the bypass circuit of the hot water circulation circuit is connected to a position between the first heat exchanger and the second heat exchanger and from approximately the center to the bottom of the hot water storage tank. A solar heat pump water heater according to claim 1 or 2. {4} In the hot water circulation circuit, the hot water circulation circuit that exits the first heat exchanger is connected to substantially the upper part of the hot water storage tank via a thermo valve in the middle thereof. The solar heat pump water heater according to item 1.
