ステムに関するものである。[Detailed Description of the Invention] Industrial Field of Application The present invention is particularly applicable to heat pump water heaters that utilize solar heat.
It concerns the stem.

あり、当然省エネルギ効果にも限度がある。Configuration of conventional examples and their problems Conventional heat pump water heaters of this type include systems that use an air heat source, systems that supplement the air heat source and use hot water obtained from a solar heat collector as a heat source to assist the heat pump, or systems that supplement the heat pump with hot water obtained from a solar heat collector. A system using a direct expansion type collector, which itself is configured as an evaporator of a heat pump, has been proposed. In these conventional methods, heat pump water heaters using an air heat source heat up by absorbing heat from the outside air, so it is impossible to operate the heat pump's evaporator at a temperature higher than the outside air temperature. There is a limit to the COP, and naturally there is a limit to the energy saving effect.

していない。In addition, in addition to the above air heat source method, in a system that uses hot water obtained from a solar collector as a heat source, compared to only an air heat source, the heat pump's CO2 is reduced due to the rise in evaporation temperature during solar radiation.
Although we can expect an improvement in P and the resulting energy saving effect,
Separate hot water circulation pump for solar heat collection configuration,
The increase in equipment such as water piping and heat exchangers with heat pumps, the need to ensure that the circulating water system does not freeze in winter, and the complexity of controlling the mutual operation of the heat collection circuit and heat pump system have made it beyond practical use.

温の確保をいかにするかの問題がある。In addition, in the case of a direct expansion type collector type in which the solar heat collector is used as the heat pump's evaporator, the collector directly constitutes the heat pump's evaporator, so the evaporation temperature rises during sunlight, and the heat pump's temperature increases accordingly. Improvements in COP and energy saving effects can be expected compared to air heat source systems. In addition, circulation to the collector is simple because it is the heat pump refrigerant circuit itself. However, in the direct expansion collector type, the refrigerant evaporation and heat collection itself in the collector is a heat pump operation, so even though the solar heat collection function is solely operated, the compressor operation is required. In addition, it is not possible to remove the compressor power even when there is no sunlight, and there are also problems with how to operate the heat pump in the absence of sunlight and how to ensure the temperature of the hot water.
