Title:
AIR CONDITIONING DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/088484
Kind Code:
A1
Abstract:
An air conditioning device, comprising: a refrigerant circulation circuit (A) configured by connecting, by pipes, a compressor (10) that compresses a heat source-side refrigerant, a first refrigerant flow path switching device (11), a heat source-side heat exchanger (12), a throttle device (26), and one or a plurality of inter-heating-medium heat exchangers (25) that exchange heat between the heat source-side refrigerant and a heating medium differing from the heat source-side refrigerant; a heating medium circulation circuit (B) configured by connecting, by pipes, one or a plurality of pumps (31) for circulating the heating medium for the heat exchange between the inter-heating-medium heat exchangers (25), a usage-side heat exchanger (35) that exchanges heat between the heating medium and the air for the air conditioning space, and flow path switching devices (32, 33) that switch between passage of the heated heating medium or passage of the cooled heating medium, through the usage-side heat exchanger (35); and a control device (60) that drives the pumps (31) at a prescribed pump capacity or greater, when performing a heat recovery and defrosting operation that causes the heat source-side refrigerant heated by the heating medium in the inter-heating-medium heat exchangers (25) to flow to the heat source-side heat exchanger (12), and defrosts.
