サイクルを維持できなくなることがある。 Conventionally, in a heat transfer device that sequentially connects a refrigerant circulation pump, a refrigerant heating evaporator, and a user-side heat exchanger, the refrigerant circulated by the action of the refrigerant circulation pump is heated in the refrigerant heating evaporator and converted from liquid refrigerant. The refrigerant becomes a gaseous refrigerant, is sent to the heat exchanger on the user side, and the cycle of liquefying and releasing heat is repeated. If the heating amount in the refrigerant heating evaporator is constant and the amount of heat released in the heat exchanger on the user side decreases, the pressure in the cycle will increase, so if the amount of heat released in the heat exchanger on the user side decreases. In this case, it is necessary to reduce the heating amount of the refrigerant heating evaporator to prevent the pressure within the cycle from rising abnormally. However, when the heating amount is reduced, the refrigerant circulating through the refrigerant heating evaporator is not completely gasified, but becomes a so-called two-phase state containing a portion of liquid refrigerant, and flows out from the refrigerant heating evaporator. As a result, the amount of refrigerant present in the piping between the outlet of the refrigerant heating evaporator and the inlet of the heat exchanger on the user side increases, and a large amount of refrigerant is required for the entire cycle system, resulting in a shortage of refrigerant and maintaining an appropriate heat transfer cycle. You may not be able to do it.

The amount of refrigerant circulated is also reduced, so that there is always no shortage of refrigerant in the heat transfer cycle.

Reference numeral 3 designates a heat exchanger on the user side, which is sequentially connected in an annular manner via a gas pipe 4 and a liquid pipe 5 to form a heat transfer cycle. A bypass valve 6 is provided in parallel to the refrigerant circulation pump 1. Combustion devices 7a and 7b are located below the refrigerant heating evaporator 2, respectively. 8a is a first fuel supply valve, and 8b is a second fuel supply valve. That is, the first fuel supply valve 8

The fuel supply valve 8b opens and fuel is supplied to the combustion devices 7a, 7b. By igniting it, combustion begins. Therefore, the refrigerant sent out from the refrigerant circulation pump 1 and flowing into the refrigerant heating evaporator 2 is heated by the heat of combustion, evaporates, and gasifies, then exits the refrigerant heating evaporator 2, passes through the gas pipe 4,
It flows into the user-side heat exchanger 3, radiates heat through the action of the blower fan 9, and is condensed and liquefied. The liquid then passes through the liquid pipe 5 and flows into the refrigerant circulation pump 1 again. During such heat transfer operation, if the amount of heat released by the heat exchanger 3 on the user side decreases, the pressure of the cycle increases. In this case, the second fuel supply valve 8b is closed using a pressure switch (not shown), etc. The fuel supply to the device 7b is stopped, and the bypass valve 6 installed in parallel with the refrigerant circulation pump 1 is opened. By these operations, the amount of heating to the refrigerant heating evaporator 2 is halved, and the amount of refrigerant circulated to the refrigerant heating evaporator 2 is also reduced. That is, the refrigerant circulation pump 1
A part of the refrigerant liquid sent out from the refrigerant circulation pump 1 returns to the inflow side of the refrigerant circulation pump 1 via the bypass valve 6.

In a heat transfer device formed by sequentially connecting a refrigerant heating evaporator and a user-side heat exchanger, the amount of heating to the refrigerant heating evaporator is made variable, and a bypass valve is added in parallel with a refrigerant circulation pump, When the heat input to the refrigerant heating evaporator is reduced, the amount of refrigerant circulated is reduced to ensure complete evaporation of the refrigerant in the refrigerant heating evaporator, and in any case, the gas pipe is Therefore, the refrigerant distribution within the device does not change due to the presence of a large amount of refrigerant in the gas pipe, and the refrigerant amount distribution is always appropriate. can be maintained. This prevents gas from entering the refrigerant circulation pump and provides stable heat transfer characteristics.
