Title:
AIR CONDITIONING SYSTEM
Document Type and Number:
Japanese Patent JP2023060410
Kind Code:
A
Abstract:
To appropriately perform air-conditioning of an air-conditioned space while suppressing energy use amounts of a heat source machine and a pump.SOLUTION: An air conditioning system 1 includes a heat source machine 30, a refrigerant flow passage, a pump, a valve, an air-conditioning control section 92 and a control device 16. An upper limit value of an opening of the valve is preset, and the opening of the valve and a refrigerant delivery temperature that is a temperature of a refrigerant delivered from the heat source machine 30 are associated with respect to each thermal load of an air-conditioning unit 10. On the basis of a current thermal load of the air-conditioning unit 10, the control device 16 sets a set temperature of the refrigerant delivery temperature in the heat source machine 30 to a temperature enabling a total energy use amount that is a total of an energy use amount of the heat source machine 30 and an energy use amount of the pump to become minimum within a range of the refrigerant delivery temperature in which the opening of the valve becomes the upper limit value or lower.SELECTED DRAWING: Figure 1
