摘要： PURPOSE:To diminish generation of ineffective refrigerant and useless heating by storing an upper limit heating amount equivalent to a deterioration with age in a memory. CONSTITUTION:The heating amount of a heater 2 is increased or reduced within a specified range between a predetermined maximum heating amount and a predetermined minimum heating amount and corresponding to a load such as chilled water, and when an excess amount of refrigerant becomes a specified value or larger, the upper limit heating amount of time heater 2 is reduced. After that, a heating amount controller 26 increases the upper limit heating amount of the heater 2 when the excess amount of refrigerant is less than a specified value and a differential temperature between the chilled water temperatures at present and at the time when the upper limit heating amount is reduced is a specified value or larger. A memory 26 stores the proper upper limit heating amount set by the heating amount controller 26. Thereby, generation of ineffective refrigerant and useless heating can be diminished.

摘要： PURPOSE:To provide an absorption type cold or hot water heater in which a reduction in capability caused by aging such as a clogging and the like is not produced. CONSTITUTION:An absorption type cold or hot water heater is comprised of a regenerator 1 with a combustion device 2 being applied as a heat source, an absorbing device 9, a condensor 3 and an evaporator 5. Either a pressure or a temperature of either the condensor 3 or the regenerator 1 is varied in response to a liquid surface of the regenerator so as to control a flow rate of rich liquid. When the flow rate of rich liquid in the regenerator is decreased, the pressure of the condensor is increased and accordingly a flow rate control is carried out in such a manner that the flow rate of the rich liquid is increased in view of its pressure.
