Rated operation is performed at the space temperature C, and when the cooling load decreases and the space temperature TA begins to drop, the temperature sensor (S
), the flow control valve (V
The opening degree of F) is reduced and the dilute solution pump (PLA
), the discharge amount of the cold water pump (FW), and the cooling water pump (PC) are reduced from their rated discharge amounts, and partial load operation is started. By throttling the flow rate control valve (V, ), the amount of refrigerant generated in the high temperature generator (1) is reduced. At the same time, the discharge amount of the cooling water pump (PC) is reduced, thereby reducing the amount of refrigerant generated in the absorber (6). The saturated temperature and saturated vapor pressure of the concentrated solution sprayed in the cooler (29) begin to rise, and the refrigerant absorption action of the absorber (6) and the refrigerant vaporization action of the evaporator (5) are suppressed, and the chilled water output is partially reduced. In addition, by reducing the discharge volume of the dilute solution pump (PLA), the sensible heat consumption of the solution in the high temperature generator is saved, and the thermal efficiency in partial load operation is also improved. do. Furthermore, since the amount of heat absorbed by the heat exchange unit (Hex) is reduced by reducing the discharge amount of the chilled water pump (Pw), a space ( A) It also prevents transient excessive cooling [in the room].However, due to the delay in adjusting the chilled water output, the temperature of the chilled water flowing out from the absorption refrigerator* (MA) may drop more than necessary transiently. However, in the operation control of the absorption chiller according to the present invention, the chilled water output is adjusted by detecting the temperature of a space with a large heat capacity; Unlike conventional systems, there is no need to repeatedly increase or decrease the valve opening or pump discharge amount due to sensitive temperature fluctuations in cold water, and it is easier to match the detection side and control side, making it easier to match than conventional systems. It has the advantage of making it easy to match the cooling load and chilled water output.As a result, compared to conventional systems, there is less hunting in the temperature of the space (A) [inside the room] during partial loads, and the generator is often It is possible to maintain more efficient operation than conventional systems, which are forced to operate unstablely by increasing or decreasing the amount of heating.

力の過度の低下防止にある。In addition, in the operation control of the present invention, when the temperature TA of the space is 2
When the temperature drops below 2°C, the fuel supply to the high temperature generator (1) is cut off, and the discharge volumes of the pumps (PtA), (PW), and (PC) are set to 25%, 50%, and 50% of their rated values, respectively. It is set like this. The reason for this is to prevent local heating of the high temperature generator (1), to prevent cold water from freezing, and to prevent excessive reduction in the refrigerant absorption capacity of the absorber (6).

Further, the flow rate adjustment may be performed by controlling the opening degree of a flow rate control valve instead of controlling the pump discharge amount.
