In the above case, when the fluid to be heated flows through the absorption heat pump under rated conditions, the flow rate of water as the fluid to be heated to the absorption heat pump is 100 m 3 / h, the water temperature on the inlet side of the absorption heat pump is 30 ° C., When the heat pump is operated under the condition that the water temperature at the outlet side is 70 ° C [warm water output 4000Mcal / h], the liquid level of the refrigerant sump (10) of the evaporator (4) is at the rated level [for example, sump ( 10)], the flow control valve (V) is kept at the rated opening. Now, for example, when the flow rate of water is reduced to 50 m 3 / h, the refrigerant absorption capacity of the absorber (5) decreases, and the refrigerant vaporization capacity of the evaporator (4) without this is, in other words, the evaporator (4). ), The ability to pump heat from the heat source water decreases, and the operating efficiency of the absorption heat pump deteriorates. At this time, since the liquid level of the refrigerant liquid reservoir (10) of the evaporator (4) also rises, if it is left as it is, the refrigerant liquid overflows from the refrigerant liquid reservoir (10) and the inside of the absorber (5) Will be mixed in the solution,
The operating efficiency of the absorption heat pump becomes worse.

In such a case, in this device, the liquid level sensor (S L ) detects the rise of the liquid level and sends it to the controller (C L ) as a signal, and the controller (C L ) receiving this signal The opening amount of the flow control valve (V) is controlled to be decreased so that the position of the regenerator (1) is returned to the rated level. As a result, the amount of the refrigerant separated from the solution in the regenerator (1) decreases, and the amount of the refrigerant liquid flowing into the evaporator (4) via the condenser (2) decreases, and the refrigerant sump (10)
The overflow of the refrigerant liquid from the inside is prevented. That is, it is possible to prevent the operation efficiency of the absorption heat pump from being lowered due to the overflow. The reduced amount of the heat source steam supplied to the regenerator (1) will be supplied to the generator turbine (17). By the way, the flow rate of water as the fluid to be heated is 50
m 3 / h, when the water temperature on the absorption heat pump inlet side changes to 10 ° C, the liquid level in the refrigerant reservoir (10) is maintained at the rated level by the capacity control of this device, and the water temperature on the absorption heat pump outlet side is 90 ° C. And a hot water output of 4000 Mcal / h is obtained.

On the other hand, when the flow rate of water as the fluid to be heated is increased to 200 m 3 / h, the liquid level in the refrigerant sump (10) drops, contrary to the decrease in the flow rate of water. signal by the controller (C L) of (S L) is to increase control of the opening of the flow control valve (V). As a result, the concentration of the solution in the regenerator (1) is increased, in other words, the amount of refrigerant separated from the solution is increased, and the amount of refrigerant liquid flowing into the evaporator (4) via the condenser (2) is increased. It increases and the liquid level in the refrigerant liquid reservoir (10) begins to rise again. Then, the concentration of the solution circulating through the heat pump is returned to the same as before the increase of the flow rate of the fluid to be heated [water], and the flow rate of water in the cooler (8) of the absorber (5) is increased. Since the refrigerant absorption capacity of the refrigerant is increased, the refrigerant vaporization capacity of the evaporator (4) is improved compared to before the increase of the water flow rate. Therefore, the heat pumping capacity of the evaporator of the heat pump is improved, the operating efficiency of the heat pump is increased, and the hot water output is also increased.

In this way, this device maintains the refrigerant liquid storage amount in the evaporator (4) at the rated value [almost the entire capacity of the refrigerant liquid reservoir (10)] while adjusting the heating amount of the regenerator (1). For example, it exerts the function of keeping the concentration of the solution at the highest concentration possible in the absorption heat pump. Then, according to this device, when the flow rate of water (fluid to be heated) to the heat pump is reduced or when the inflow temperature of water to the heat pump is increased, the solution is maintained at the same concentration as before the change. In other words, it is possible to prevent the heat loss that accompanies this.
On the other hand, when the flow rate of water is increased or the inflow temperature is decreased, it is possible to exert a greater refrigerant absorbing power than before the change. Therefore, the heat pump evaporator (4)
It is possible to maintain the high heat pumping ability, that is, the operating efficiency of the heat pump at a high level.

It is needless to say that the above-mentioned rated level can be set to any level other than the upper limit level of the refrigerant liquid reservoir (10).
This setting is made by arbitrarily setting the volume (resistance value) of the level setter (not shown) of the controller ( CL ).

In addition, in this device, when the temperature of the water (heated fluid) flowing out from the heat pump exceeds 100 ° C , the relay contact of the changeover switch ( RC ) is switched to the H side by the temperature controller (C T ). is, the flow control valve (V) is throttled by a signal of the temperature sensor (S T). This prevents the inside of the cooler (9) from becoming higher than atmospheric pressure.
