にある。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a heat collecting device for a solar air-conditioning, heating, and water-heating system that collects and stores solar heat through a heat medium and supplies the heat to an air-conditioning, heating, and water-heating system. The purpose is to efficiently collect heat by switching the heat collecting circuit depending on the heat collecting temperature and changing the position of a differential temperature thermostat that controls the heat collecting pump.

が行なわれない。 It is already known that a heat medium heated by solar heat can be used to operate air conditioning equipment or to supply hot water. While it is sufficient to heat water for hot water supply to about 40°C, in order to directly operate an air-conditioning device using a heat medium, a high temperature of 50°C to 80°C or higher is required. That is, in a heating system, a radiator requires hot water of at least 50°C, and in a cooling system, such as an absorption water cooler, hot water of 75°C or higher is required. Therefore, solar heat can be effectively utilized for heating and cooling by preferentially collecting heat so that the heating and cooling equipment can operate during the periods when air conditioning or heating is used, that is, in summer and winter. For this purpose, when the temperature of the heat medium in the heat collector is low, it is not circulated to the heat storage device.
There is a method in which the heat medium is circulated only through a heat collector, and then when the heat medium reaches a high temperature, the heat is stored in a heat storage device. Tokuko Akira
No. 55-26378, Japanese Patent Application Publication No. 140057, No. 55-14005, Publication No. 55-26378
No. 7774 was devised for the aforementioned purpose. In order to efficiently collect heat, it is necessary to detect the presence or absence of solar radiation using a difference temperature signal between the temperature of the heat medium in the heat collector and the temperature of other non-heated heat media, and to control the heat collection pump. In the conventional example described above, efficient heat collection is not performed because the temperature difference thermostat is not switched when switching between the heat medium heating circuit that does not store heat and the heat collection circuit that stores heat.

That is, in FIG. 1, the cooling/heating heat collecting three-way valve 3 flows from a to c, the hot water supply heat collecting three-way valve 9 flows from b to c, and the temperature difference signal of the heat collecting pump controller PC is connected to the high temperature side temperature detector 15. It is obtained from the first low temperature side temperature sensor 16. When there is solar radiation, a temperature difference signal is generated, the comparator C 1 is activated, the relay coil RL 4 is energized, the relay contact RL 4 (S) is closed, and the motor PM of the heat collection pump 4 is activated. At this time, the heat medium is the heat collector 1, the cooling/heating bypass pipe 8, and the cooling/heating heat collection three-way valve 3.
(a to c), the hot water supply bypass pipe 9, and the hot water supply heat collection three-way valve 9 (b to c) in this order to form a rapid heating circuit. When the temperature of the heat medium is low and the amount of solar radiation is small, that is, in the morning, the heat medium is transferred to the cooling/heating heat storage device 2 and the hot water supply heat storage device 5 in this rapid heating circuit.
Raise the temperature rapidly without accumulating heat.
When the temperature of the heat medium reaches a temperature sufficient to operate the air-conditioning device 13, the comparator C2 is activated by a change in the thermistor resistance RT5 of the temperature detector 10, and the relay coil RL5 is energized (relay contact RL 1
(S 2 ) is closed), relay contact RL 5 (S 3 ) is opened to stop energizing the electromagnetic coil VM 1 . That is, in order to change the flow of the cooling/heating heat collecting three-way valve 3 from b to c, the heat medium is transferred to the heat collector 1, the cooling/heating heat storage device 2, the cooling/heating heat collecting three-way valve 3 (from b to c), the hot water supply bypass pipe 9, The hot water circulates in the order of the three-way hot water collection three-way valves 7 (b to c) to form a heating heat collection circuit, and the high temperature heat medium is stored in the upper part of the heating and cooling heat storage device 2. Therefore, the air-conditioning device 13 can be operated sooner.

れる。 Simultaneously, relay contact RL 5 (S 1 ) opens, relay contact RL 5 (S 2 ) closes, and the thermistor resistance of bridge B 1 is switched from RT 2 to RT 3 . That is, the temperature difference signal is obtained from the high temperature side temperature detector 15 and the second low temperature side temperature detector 17. Operation switch SW
When S 2 is set, relay coil RL 3 is energized, relay contacts RL 3 (S 1 ) and RL 3 (S 2 ) are closed, and relay contact RL 3 (S 3 ) is opened.
Since VM 1 is not energized and the electromagnetic coil VM 2 is energized, the heat medium is transferred to the heat collector 1, the cooling/heating heat storage device 2,
Air conditioning circulates in the order of the cooling/heating heat collection three-way valve 3 (b to c), the heat exchanger 6, and the hot water supply heat collection three-way valve 7 (a to c), and stores heat in both the cooling and heating heat storage device 2 and the hot water supply heat storage device 5. It becomes a hot water supply heat collection circuit. At this time, relay contact RL 1 (S 2 ) is open, so relay coil RL 5
is not energized, and the cooling/heating heat collection three-way valve 3 is connected to the temperature detector 1.
It will not be switched by a 0 signal. The temperature difference signal of the heat collecting pump controller PC is thermistor resistance.
Obtained from RT 1 and RT 4 . That is, the heat collection pump 4 is controlled by the temperature difference between the high temperature side temperature detector 15 and the third low temperature side temperature detector 18. driving switch
When SW is set to S 3 , relay coils RL 2 and RL 3 are energized, and relay contacts RL 3 (S 1 ), RL 3 (S 2 ), RL 2
(S) are closed and the electromagnetic coils VM 1 and VM 2 are energized, so the heat medium is transferred to the heat collector 1, the cooling and heating bypass pipe 8, the cooling and heating three-way collector valve 3 (a to c),
The hot water circulates in the order of the heat exchanger 6 and the three-way hot water collection three-way valve 7 (a to c), forming a hot water collection circuit that stores heat only in the hot water heat storage device 5. This time difference temperature signal is the same as that of the cooling/heating/hot water supply heat collecting circuit, and the heat collecting pump 4 is controlled by the difference in temperature between the high temperature side temperature detector 15 and the third low temperature side temperature detector 18.

い。 As described above, the present invention stores heat only in the cooling/heating heat storage device in the cooling/heating heat collection circuit, and when the heat medium temperature is low, the heat medium is circulated bypassing the cooling/heating heat storage device to rapidly raise the temperature of the heat medium. Since the position of the differential temperature signal that controls the heat collection pump is switched at the same time as the heat collection circuit is switched, each circuit can operate with the highest heat collection efficiency.
It has high practical value as it can effectively utilize solar heat for heating and cooling.
