を有していた。 In the above configuration, by driving the compressor 1, the refrigerant gas compressed to high temperature and high pressure is transferred to the condenser 2.
flows into. Here, the water heater 10, which is in a heat transfer relationship with the condenser 2, radiates heat to the flowing hot water by the action of the water circulation pump 9, and condenses and liquefies it.Then, the pressure is reduced by the expansion valve 3, and the temperature becomes low, and it flows into the heat collector 4. It flows in and evaporates. Here, since the evaporation temperature of the refrigerant is set lower than the atmospheric temperature, the refrigerant absorbs heat from the solar heat and atmospheric heat, becomes evaporative heat, and is sucked into the compressor 1 again.
On the other hand, the hot water heated by the water heater 7 is sequentially stored in the hot water storage tank 5. As shown in Figures 8 and 9,
When the heat collector 4 that directly receives solar heat or atmospheric heat is installed vertically and there is no wind, the surrounding air becomes cold air due to the heat absorption action of the heat collection fins 12 of the heat collector 4, resulting in a draft phenomenon. As the cold air descends, the lower the heat collector 4 is, the more the cold air affects the heat collector 4, reducing its performance. The larger the arrow in the figure, the stronger the degree of cold air. Note that the ring lines in the figure indicate cold air isotherms. In other words, if the outside temperature is t 0 and the refrigerant temperature is t R , the temperatures in between are t 1 , t 2 , etc.
They can be connected by isotherms of t 5 and t 6 . There is a relationship between these temperatures: t 0 > t 1 > t 2 > t 3 > t 4 > t 5 > t 6 > t R. Also, thick arrows indicate new air flow. When the capacity decreases, the circulation of the refrigerant becomes unstable, which places a burden on the compressor 1. In addition, since the large number of heat collecting fins 12 are provided with certain gaps, when the sun comes near a position parallel to the plane of the heat collecting fins 12, the sunlight passes through the gap between the heat collecting fins 12 or Heat collection fin 12
After a small amount of sunlight hits the surface of a surface, almost all of it is reflected and passes through without being effectively collected. The arrow in the figure indicates sunlight. Although not shown, if the entire surface is made of a single heat collecting surface, it is effective against sunlight, but it has problems such as having the opposite effect on collecting atmospheric heat in windless or windy conditions.

A condenser, an expansion valve, and a heat collector are connected as a refrigerant circulation circuit, a hot water storage tank having a water inlet and a hot water outlet, a water circulation pump, and a water heater are connected as a water circulation circuit, and the condenser and water heater are connected as a water circulation circuit. A heat transfer relationship is formed, and the heat collection fins of the Finch-Ube type heat collector are bent alternately into a U-shape and an inverted U-shape, and the bending line is made at an inclination angle with respect to the center line of the fin. It is something that has

受光面として働き集熱を高める。 With this configuration, when there is no wind when the heat collector is installed vertically, the air around the top of the heat collector becomes cold due to the heat absorption action of the heat collecting fins. Since it is bent in a U-shape, it is the same as creating a partition between the heat collecting fins.Furthermore, since this bent part has an inclined angle, it is possible to create a partition between the heat collecting fins along the inclined surface. Cold air flows down to one side. This draft causes fresh air to flow in from the other side. In addition to reducing the influence of falling cold air at the lower part of the heat collector, the bent surface acts as a light receiving surface without allowing sunlight to pass through, increasing heat collection.

間を延長することができる。 In the above configuration, by driving the compressor 1, the refrigerant gas compressed to high temperature and high pressure is transferred to the condenser 2.
The hot water flows into the water heater 10 through the action of the water circulation pump 9 and radiates heat to the hot water flowing through the water heater 10, causing it to condense and liquefy.
Next, the circulating refrigerant is depressurized by the expansion valve 3, becomes low temperature, flows into the heat collector 4, and evaporates. Since the evaporation temperature of the refrigerant is set lower than the atmospheric temperature, the refrigerant absorbs solar heat and atmospheric heat, converts it into evaporative heat, and is sucked into the compressor 1 again. On the other hand, the hot water heated by the water heater 7 is sequentially stored in the hot water storage tank 5. As shown in Figure 10, when there is no wind when the heat collector 4 is installed vertically,
The air around the upper part of the heat collector 4 becomes cold air due to the heat absorption action of the heat collecting fins 12.
U-shape 13 and inverted U-shape 1 so as to form an inclination angle α
Since the center line 16 and the bending line 15 of the heat collecting fins 12 are bent at an inclination angle α, the cold air between the heat collecting fins 12 flows down to one side along the inclined surface. The larger the arrow in the figure, the stronger the degree of cold air. Note that the ring lines in the figure indicate cold air isotherms. In other words, if the outside temperature is t 0 and the refrigerant temperature is t R , the temperatures between them are t 1 , t 2 , etc.
They can be connected by the t 5 isotherm. There is a relationship between these temperatures: t 0 > t 1 > t 2 > t 3 > t 4 > t 5 > t R. Also, thick arrows indicate new air flow. Due to this draft effect, new air flows in from the other side, reducing the influence of cold air even at the lower part of the heat collector 4, and as shown in FIG. heat fin 1
It prevents sunlight from passing through the gap between the two, acts as a light-receiving surface, and increases heat collection. Arrows in the figure indicate sunlight rays. Note that fresh outside air always flows into the heat collector from one side due to the draft effect, so it is less likely to be covered with cold air. Therefore, frosting of the fins caused by this cold air is prevented and the amount of heat collection is improved, so that the operating time in winter can be extended.
