摘要:
An unit-type air conditioning system is provided to enable low-load operation of an absorption chiller heater, to thereby improve the load responsiveness, and to use such a chiller heater as an outdoor unit. A plurality of burners are provided in a high temperature generator of the absorption chiller heater, thereby enabling the low-load operation. A refrigerant return valve is provided so as to speed up the stop operation. Flow rates of pumps are controlled in accordance with detected values of temperatures in the chiller heater and a load change, thus improving the load responsiveness. Further, in the air conditioning system with this chiller heater serving as an outdoor unit, required operation prediction is performed on the basis of outer signals from load units and the like, and prediction control according to its result is conducted, further improving the load responsiveness.
