Abstract
An individual air conditioning system with an absorption chiller heater having a controllable capacity, with thermal input to a burner of a high temperature regenerator being controlled by on-off control or the like even if the load is low. The temperature of cooling water is controlled in accordance with a concentration of refrigerant in an absorber, so that the refrigerating capacity of the absorption chiller heater can be freely varied from 0% to 100% without the refrigerant being frozen.
