ームサーモを示す。 A conventional heating device is shown in FIG. A refrigerant heating heat exchanger 1 that performs a refrigerant evaporation action and a user-side heat exchanger 2 that performs a refrigerant condensation action are connected in an annular manner via a refrigerant circulation pump 3 to form a closed circuit. R-22 In a heating device that includes a combustion device 4 that encloses an appropriate amount of fluorocarbon refrigerant such as R-12 or R-11 and heats the refrigerant heating heat exchanger 1, the combustion device 4 and the refrigerant circulation pump 3 are When activated, the liquid refrigerant sent from the refrigerant circulation pump 3 to the refrigerant heating heat exchanger 1 is heated by the combustion heat generated in the combustion device 4, evaporates into gas, and passes through the piping to the user-side heat exchanger 2. It flows in, exchanges heat with the indoor air, and performs the action of dissipating and condensing the heat. Here, for example, if the fuel supply to the refrigerant circulation pump 3 and the combustion device 4 is cut off in conjunction with the indoor room thermostat, even if the refrigerant circulation pump 3 is stopped, the residual heat of the refrigerant heating heat exchanger 1 , a temperature difference occurs between the refrigerant heating heat exchanger 1 and the user-side heat exchanger 2, and the refrigerant causes a natural circulation effect. As a result, the liquid refrigerant present on the suction side of the refrigerant circulation pump 3 flows between the refrigerant heating heat exchanger 1 and the user-side heat exchanger 2, and the gaseous refrigerant and liquid refrigerant on the suction side of the refrigerant circulation pump 3. will coexist. In such a case, when the refrigerant circulation pump 3 and the combustion device 4 operate again, liquid refrigerant is no longer sent to the refrigerant heating heat exchanger 1, and a normal circulation cycle is no longer performed. In addition, 5 is gas side piping, 6 is liquid side piping,
8 is an on-off valve that controls the supply of fuel to the combustion device 4, 9 is a blower for the user-side heat exchanger 2, and 10 is a room thermostat.

The blower 9 is operated in conjunction with an operation switch (not shown), and the refrigerant circulation pump 3 and the on-off valves 7 and 8 are operated by the thermostat 10, and fuel is supplied to the combustion device 4 to start combustion. On the other hand, liquid refrigerant is sent to the refrigerant heating heat exchanger 1 by operating the refrigerant circulation pump 3 . Here, the liquid refrigerant is heated by the heat of combustion, evaporates, and flows into the user-side heat exchanger 2 through the gas-side pipe 5. The refrigerant then exchanges heat with the indoor air sent by the blower 9, radiates heat, and condenses, becoming a liquid refrigerant that passes through the liquid side piping 6 and is sucked into the refrigerant circulation pump 3. Further, the liquid refrigerant discharged from the refrigerant circulation pump 3 passes through the on-off valve 7 and is sent to the refrigerant heating heat exchanger 1 again. In other words, the refrigerant undergoes isothermal and isobaric state changes. In the above operation, when the room temperature reaches the set temperature, the thermostat 10
is activated, and the refrigerant circulation pump 3 is stopped, the on-off valve 8 is closed, and the fuel supply to the combustion device 4 is cut off. Further, the refrigerant circulation circuit is closed between the on-off valve 7 in the refrigerant circuit, that is, the refrigerant circulation pump 3 and the refrigerant heating heat exchanger 1. As a result, the refrigerant heating heat exchanger 1
Natural circulation of the refrigerant caused by the temperature difference between the refrigerant and the user-side heat exchanger 2 due to residual heat is prevented, and the refrigerant circulation pump 3 is always filled with liquid. In addition, by stopping the circulation of the refrigerant, the refrigerant heating heat exchanger 1 due to residual heat
It is possible that the temperature of the refrigerant inside the tank has increased, but since the liquid refrigerant is being sent until just before it stops, and some liquid refrigerant remains immediately after it stops, the temperature rise is less than 15 degrees. There is no problem as it is much lower than the deterioration temperature of the refrigerant.
次に室温が低下して、再び燃焼装置４が作動し
ても、冷媒循環ポンプ３は液冷媒で満されている

給され、円滑な暖房作用を行なう。 Next, even if the room temperature drops and the combustion device 4 is activated again, the refrigerant circulation pump 3 is filled with liquid refrigerant, so the refrigerant heating heat exchanger 1 is supplied with the necessary liquid refrigerant, and the refrigerant heating heat exchanger 1 is smoothly operated. Performs heating action.

現させることができ作用効果を生ずる。 As explained above, the present invention connects a refrigerant heating heat exchanger, a user-side heat exchanger, and a refrigerant circulation pump sequentially in an annular manner, and provides an on-off valve between the refrigerant circulation pump and the refrigerant heating heat exchanger. By closing the on-off valve when the refrigerant circulation pump and the combustion device are stopped, the refrigerant's natural state due to the temperature difference with the user-side heat exchanger caused by residual heat in the refrigerant heating heat exchanger is reduced. Since circulation is prevented and the refrigerant circulation pump is always filled with liquid refrigerant, liquid refrigerant is reliably supplied to the refrigerant heating heat exchanger upon restart, and an appropriate heating effect can be reproduced, producing an effect.
