Title:
AIR CONDITIONING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/171401
Kind Code:
A1
Abstract:
An air conditioning apparatus according to the present invention comprises: a coolant circuit in which a compressor, a heat source-side heat exchanger including a first heat source-side heat exchanger and a second heat source-side heat exchanger connected in parallel, a load-side throttle device, and a load-side heat exchanger are connected, and a non-azeotropic mixed coolant is circulated; first coolant piping and second coolant piping that divide the flow of coolant flowing out from the load-side throttle device during a heating operation and cause the coolant to circulate to the heat source-side heat exchanger; a first throttle device that reduces the pressure of coolant flowing into the first heat source-side heat exchanger through the first coolant piping during a heating operation; a second throttle device that reduces the pressure of coolant flowing into the second heat source-side heat exchanger through the second coolant piping during a heating operation; and a coolant-to-coolant heat exchanger that exchanges heat between a coolant circulating between the second throttle device and the second heat source-side heat exchanger and a coolant flowing into the first throttle device during a heating operation. The pressure loss of coolant circulating through the first heat source-side heat exchanger is greater than the pressure loss of coolant circulating through the second heat source-side heat exchanger.
