るものである。Structure of the Invention In order to achieve this object, the present invention mainly consists of a heat collector that collects solar heat and a heat exchanger installed in a hot water storage tank provided above the heat collector in a loop-type heat pipe. The above-mentioned heat exchanger or a separate heat exchanger is installed in the hot water storage tank to mainly collect atmospheric heat using a heat pump circuit and then condense the heat transfer medium, and the heat exchanger or a separate heat exchanger is installed in the middle of the main pipe at a position higher than the heat collector. The liquid level detection means detects changes in the magnetic field of a float containing a magnetic material inserted inside the float and a float provided outside. It consists of two parts: a coil or reed switch, a float movable area, and a fence provided at the bottom.

熱集熱を行うことかできる。With this configuration, when solar radiation is large, solar heat is collected by the loop heat pipe, heat is transferred from the collector to the heat exchanger, and the condensate is guided to the lower part of the collector through the source tube. In this case, the liquid level in the return pipe, if the loop type heat pipe is working, will be compared to the state when it is not working,
In order to obtain circulation force, the liquid must rise, resulting in an obvious difference in liquid level height. In this case, the float of the liquid level detector floats and sends a signal to the controller due to changes in the magnetic field. Therefore, when the liquid level inside the refractory is high, solar heat collection is occurring and the heat pump does not operate, but when there is no sunlight or the temperature inside the hot water storage tank rises, the loop heat pipe is activated. If not, the liquid level in the return pipe will be equal to the liquid level in the heat collector, and the float in the liquid level detector will fall to the bottom. In that case, a signal will be sent to start the compressor in the heat pump circuit. It is possible to collect atmospheric heat by operating a heat pump.

構成になっている。In Fig. 2, 1 is a heat collector that mainly collects solar heat, 2 is a hot water storage tank located above the heat collector 1, and has a condensing heat exchanger 3 installed inside. The tube 5 constitutes a closed circuit. After evacuation, the closed circuit is filled with a working fluid 6, which is a latent heat medium, to the extent that it approximately fills the entire heat collector. In addition, in the middle of the raw tube 5, the height is the same as the top of the heat collector,
Alternatively, a liquid receiving tank 7 is provided at a high position, and a float 8 is disposed inside the tank 7. Further, the float includes a magnetic material in whole or in part, and the specific gravity of the entire float 8 is configured to be smaller than the specific gravity of the hydraulic fluid. On the other hand, a coil 9 or a reed switch that detects changes in the magnetic field is installed outside the liquid receiving tank 7, so the float moves up and down according to changes in the liquid level. A signal for starting and stopping the compressor 10 can be issued via the controller 12. Moreover, net-like fences 16 are provided at the upper and lower parts of the movable range of the float 8 in the liquid receiving tank 7, so that the float 8 cannot pass through.

ることになる。In the above configuration, when the amount of solar radiation is large, or when the temperature difference between the surface temperature of the heat collector and the water temperature in the hot water storage tank is large, solar heat is absorbed in the heat collector, and the working fluid 6 inside is It evaporates and becomes a scum, which passes through the outgoing pipe 4 and is led to the heat exchanger in the hot water storage tank 2. When cooled in the hot water storage tank 2, the waste in the heat exchanger condenses and liquefies, flows down the heat exchanger tilted in one direction, passes through the raw pipe 5 and the liquid receiving tank 7, and reaches the 1z section of the heat collector. I am guided. ) When the solar radiation is large, or when the temperature difference between the surface temperature of the heat collector and the water temperature in the hot water storage tank 2 is large, the loop is operated as a heat pipe and the source is used to obtain the circulating force of the working fluid. The amount of liquid in the pipe 5 increases, and therefore the level of the working liquid in the liquid receiving tank 7 formed in a part of the recess changes depending on the amount of solar radiation.

次に受液タンク7の他の実施例を第3図に示す。As in the above embodiment, the t♀ child 8 is provided inside the liquid receiving tank 7, and this signal is generated by floating when solar radiation exceeding a certain daily amount is obtained. The operation of the compressor 10 of the heat pump circuit can be stopped via the controller 12, and when there is sunlight, heat can be collected by the heat collector without power. In addition, when there is no sunlight, or when the temperature difference between the surface temperature of the heat collector 1 and the water temperature in the hot water storage tank 2 is small, the circulating force of the loop heat pipe is not generated, so the working fluid in the return pipe is The liquid level height becomes low, and therefore the float 8 in the liquid receiving chamber emits a signal indicating that it is located downward. In this case, by starting the operation of the compressor 10 of the heat pump circuit, heat can be collected using the heat pump circuit mainly from the air heat source. In this way, the present invention provides a liquid level detection part in a part of the original pipe of the loop type heat pipe, and furthermore, the float is placed directly in the working liquid, so the working liquid level can be detected reliably. Because it is vacuumed, there is no generation of oxide scale, and there are also fences on the top and bottom of the float to act as a filter, ensuring long-term operation and ensuring heat pump operation using highly reliable means. Next, another embodiment of the liquid receiving tank 7 is shown in FIG. 3.

であってもさしつかえない。In Fig. 3, reference numeral 4 (11116) is constituted by a pawl portion 16 that protrudes into the inside of the liquid receiving tank.It also restricts only the second and lower positions of the float 8 without blocking the passage of the working liquid. However, other configurations including this embodiment may be used.

システムであってもよい。Further, the evaporator 13 and condenser 14 of the heat pump circuit in this embodiment are completely independent of the evaporator 1 and condenser 3 of the loop heat pipe circuit, and the expansion valve 15 constitutes the heat pump circuit. However, as another example,
Either or both of the evaporator and condenser may be a common system.
