Claims

[Scope of utility model registration request]

(1) A heat pump heating system consisting of a refrigeration cycle in which a solar heat absorbing collector and a forced convection heat exchanger are selectively communicated with each other by a three-way valve, and a water supply system equipped with a hot water storage tank are provided. In a solar heat pump water heater that uses a refrigerant/water heat exchanger to exchange heat between the refrigerant of the heat pump heating system and the water of the water supply system, the temperature and pressure of the refrigerant sent to the refrigerant/water heat exchanger must be kept within a specified range. A solar heat pump water heater characterized by being equipped with an adjustment device that maintains the temperature.

(2) The adjustment device controls the refrigerant in the water supply element.
It is composed of a temperature sensor that detects the water temperature of the inflow side pipe and the outflow side pipe of the water heat exchanger, and a controller that controls the rotation of the compressor of the refrigeration cycle according to the signal from the temperature sensor. A solar heat pump water heater according to claim 1 of the utility model registration claim.

(3) Registration of a utility model characterized in that the adjustment device is composed of a temperature sensor that detects the outside temperature and a controller that controls rotation of the compressor of the refrigeration cycle in accordance with a signal from the temperature sensor. A solar heat pump water heater according to claim 1.
