う弊害を生じる。(b) Conventional technology and its problems Conventionally, in absorption refrigerators (or absorption heat pumps),
A control valve is provided in the heat source steam supply pipe of the generator, and the opening degree of the control valve is controlled by load detector No. 48, and the opening degree of the control valve is increased or decreased in proportion to the increase or decrease in the detected load. Conventional heat source steam flow rate control devices, such as systems δ'' for adjusting the heat source steam flow rate, are known to adjust the flow rate of the heat source steam depending on the operating state of the equipment, such as by using waste steam discharged from a power generation plant or other equipment as a driving heat source. When the supply pressure of the heat source steam fluctuates, there is a problem that the amount of driving heat source steam commensurate with the load cannot be supplied to the absorption refrigeration frame (or the absorption 11y heat pump).In other words, in conventional equipment, for example, the cooling load does not change. Sometimes, the opening degree of the control valve is also constant V.
If the heat source steam supply pressure decreases, the flow rate of heat source steam to the generator will decrease and the driving heat source will be insufficient for the cooling load, resulting in insufficient cooling output, and conversely, the heat source steam supply pressure will decrease. When the temperature rises, the driving heat source becomes excessive for the cooling load, resulting in an adverse effect that the cooling output field exceeds 1 (so-called overcooling).

The present invention provides a heat source vapor flow control device for an absorption refrigerator (or absorption heat pump) that can adjust the drive heat source supply fl to the absorption refrigerator (or absorption heat pump) and supply an output commensurate with the load.

を制御する。The controller (C) receives a signal from the temperature sensor (Cr) via the temperature controller (13) and also receives a signal from the pressure sensor (5), and performs the following measurements, for example. It has a built-in unit that calculates and sets the valve opening degree based on the formula, and the control valve for heat source steam can open the valve in response to increases and decreases in load in response to changes in the input 1 side pressure, that is, the heat source steam supply pressure. The opening degree of the control valve (V) is controlled so that the amount of heat source steam commensurate with the load is supplied to the high temperature generator (1).
