Document Type and Number:
WIPO Patent Application WO/2023/119552
Kind Code:
A1
Abstract:
According to the present invention, an air conditioner comprises outdoor equipment, refrigerant indoor equipment, first intermediate equipment, second intermediate equipment, first heat medium indoor equipment, and a hot water tank. The outdoor equipment includes: a first compressor that circulates a first refrigerant through a first refrigerant circuit; and an outdoor heat exchanger through which the first refrigerant flows. The refrigerant indoor equipment includes a refrigerant heat exchanger through which the first refrigerant flows. The first intermediate equipment includes: a first pump that circulates a heat medium that is different from the first refrigerant through a first heat medium circuit; and a first intermediate heat exchanger that performs a heat exchange between the first refrigerant and the heat medium that circulates through the first heat medium circuit. The second intermediate equipment includes: a second pump that circulates a heat medium that is different from the first refrigerant through a second heat medium circuit; and a second intermediate heat exchanger that performs a heat exchange between the first refrigerant and the heat medium that circulates through the second heat medium circuit. The first heat medium indoor equipment includes a first heat medium heat exchanger through which the heat medium that circulates through the first heat medium circuit flows. The hot water tank stores the heat medium that circulates through the second heat medium circuit.
