Patent ID: 11274866

Abstract:
An air conditioning system includes a refrigerant circuit including a use-side circuit, heat-source-side circuit and refrigerant release circuit, a refrigerant leakage detection unit in the use-side circuit, a heat-source-side control valve that enables, when in an opened state, the heat-source-side circuit to communicate with the refrigerant release circuit, a rupture disk that is disposed in the refrigerant release circuit and enables, when in a first state (an open state), the refrigerant release circuit to communicate with an external space to release refrigerant, and a controller. When no leakage of refrigerant in the use-side circuit is detected, the controller controls the heat-source-side control valve to a. closed state. When leakage of refrigerant, in the use-side circuit is detected by the refrigerant leakage detection unit, the controller switches the heat-source-side control valve to the opened state and causes the rupture disk to shift to the first state.
