Title:

AIR-CONDITIONING DEVICE

Document Type and Number:

WIPO Patent Application WO/2017/119137

Kind Code:

A1

Abstract:

An air-conditioning device whereby it is possible to reduce the amount of usage of refrigerant and prevent leakage of refrigerant to an indoor space. This air-conditioning device is equipped with: an outdoor unit housing which houses a compressor, a refrigerant flow path switching device, and a heat-source-side heat exchanger; a heat carrier converter housing which houses a throttle device and an inter-heat-carrier heat exchanger; a heat carrier flow rate adjuster housing which houses heat carrier flow rate adjusting devices; indoor unit housings which each house a load-side heat exchanger and an indoor blower; and a heat carrier conveying device which conveys a heat carrier. The compressor, the refrigerant flow path switching device, the heat-source-side heat exchanger, the throttle device, and the refrigerant passage of the inter-heat-carrier heat exchanger are connected by a refrigerant pipe circulating the refrigerant therethrough so as to configure a refrigerant circulation circuit. The heat carrier passage of the inter-heat-carrier heat exchanger, the heat carrier conveying device, the heat carrier flow rate adjusting devices, and the load-side heat exchangers are connected by a heat carrier pipe circulating the heat carrier therethrough so as to configure a heat carrier circulation circuit.
