HOT WATER SUPPLY AIR CONDITIONING SYSTEM
First Claim
1. A hot water supply air conditioning system comprising:
- a hot water supplier including a hot water storage tank configured to store hot water to be supplied;
a thermal storage including a thermal storage tank configured to store a thermal storage medium; and
a refrigerant circuit includinga hot-water-supply-side heat exchanger connected to the hot water supplier,a thermal-storage-side heat exchanger connected to the thermal storage,a heat-source-side heat exchanger configured to exchange heat between refrigerant and outdoor air, anda utilization-side heat exchanger configured to condition room air,wherein the hot water supply air conditioning system performsa cold-storage operation in which the refrigerant circuit performs a refrigeration cycle such that the thermal-storage-side heat exchanger serves as an evaporator and the thermal storage cools the thermal storage medium of the thermal storage tank with refrigerant flowing through the thermal-storage-side heat exchanger, anda cold-used air-cooling operation in which the refrigerant circuit circulates refrigerant from the thermal-storage-side heat exchanger to the utilization-side heat exchanger and the thermal storage cools refrigerant flowing through the thermal-storage-side heat exchanger with the thermal storage medium of the thermal storage tank, andduring the cold-storage operation, the hot water supply air conditioning system performsa first operation in which the hot-water-supply-side heat exchanger serves as a radiator and the hot water supplier heats the water of the hot water storage tank with heat dissipated from refrigerant, anda second operation in which the heat-source-side heat exchanger serves as the radiator.

Abstract
A hot water supply air conditioning system performs a first cold-storage operation, a second cold-storage operation, and a cold-used air-cooling operation. In the first cold-storage operation, a hot-water-supply-side heat exchanger serves as a condenser, and a thermal-storage-side heat exchanger serves as an evaporator. Moreover, a hot water supplier heats water of a hot water storage tank, and a thermal storage stores cold thermal energy in a thermal storage tank. In the second cold-storage operation, a heat-source-side heat exchanger serves as a condenser, and the thermal-storage-side heat exchanger serves as an evaporator. Moreover, the thermal storage stores cold thermal energy in the thermal storage tank. In the cold-used air-cooling operation, the hot water supply air conditioning system cools room air using cold thermal energy stored in the thermal storage tank.
