AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2019/239556
Kind Code:
A1
Abstract:
This air conditioner comprises: a refrigerant circuit in which refrigerant circulates, the refrigerant circuit being such that a compressor, a heat-source-side heat exchanger that performs heat exchange between air and the refrigerant, an expansion part, and an inter-medium heat exchanger that performs heat exchange between the refrigerant and a heat medium are connected by refrigerant piping; a heat medium circuit in which the heat medium circulates, the heat medium circuit being such that a pump, the inter-medium heat exchanger, and a load-side heat exchanger that performs heat exchange between air-conditioned air and the heat medium are connected by heat medium piping; a discharge part connected to the downstream side of the inter-medium heat exchanger in the heat medium circuit, the discharge part discharging a fluid flowing through the heat medium piping to the outside of the heat medium piping in accordance with the pressure of the fluid; a refrigerant detection device that senses the concentration of refrigerant included in the fluid discharged from the discharge unit; a notification device that issues a notification about a leak of the refrigerant; and a control device that operates the notification device on the basis of the concentration of refrigerant detected by the refrigerant detection device.
