Abstract: A demand control device performs demand control in which energy consumption of heat source units is suppressed with regard to a heat source system having a plurality of the heat source units with capacities and/or output characteristics that are different. The demand control device includes a receiving section, a collecting section, an energy suppression amount value calculating section, a heat source output determining section, and a driving section. The receiving section receives a demand signal which requests starting of the demand control. The energy suppression amount value calculating section calculates an energy suppression amount value relating to an energy amount suppressed during the demand control. The heat source output determining section determines an output individually with regard to each of the plurality of heat source units based on the energy suppression amount value. The driving section drives each of the plurality of heat source units using the output.

Abstract: A heat source system control device controls a heat source system and has a plurality of heat source units with capacities and/or the load characteristics that are different, a first header which aggregates hot/cold water supplied from the plurality of heat source units, and a header temperature sensor which measures the temperature of the hot/cold water aggregated by the first header. The heat source system control device includes a set temperature memory section storing a set temperature of the hot/cold water in the header, a header temperature detecting section detecting output values from the header temperature sensor, a coefficient of performance memory section storing coefficient of performance information, and a control section performing a control for improving efficiency on the plurality of heat source units based on the respective capacities and/or load characteristics and bringing the temperature of the hot/cold water close to the set temperature.

Abstract: In an input section (30), a set temperature Ts which becomes a control target temperature of a humidity controller (10), and a set relative humidity Rs which becomes a control target humidity of the humidity controller (10) are set. An air conditioning control section (42) adjusts the temperature adjusting capacity of the humidity controller (10) such that the room temperature may come very close to the set temperature Ts. Further, an arithmetic section (33) calculates, as the target absolute humidity As, the absolute humidity which becomes the relative humidity set value Rs at the set temperature Ts. A humidity adjustment section (41) adjusts the humidity adjusting capacity of the humidity controller (10) such that the absolute humidity of the room may come very close to the target absolute humidity As.

Abstract: In the air conditioning system (1), switching is selectively made between a normal operation where air is dehumidified by the humidity controller (10) alone according to operating conditions and a simultaneous dehumidifying operation where air is dehumidified by the humidity controller (10), while at the same time air is dehumidified by the air conditioner (20) by condensing moisture in the air.
