Title:
REFRIGERATION CYCLE, AND AIR CONDITIONER PROVIDED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2014/092152
Kind Code:
A1
Abstract:
The present invention provides a refrigeration cycle and an air conditioner, with which the flow of refrigerant is facilitated and an optimal amount of refrigerant can be circulated. In the present invention, a flow-rate adjustment unit for adjusting the flow rate of a refrigerant flowing through a refrigerant circuit is connected in parallel to a throttle device. The flow-rate adjustment unit is provided with: a receiver in which the refrigerant is stored; a high-pressure-side connection pipe which connects the receiver and a high-pressure side of the throttle device in the refrigerant circuit; a low-pressure-side connection pipe which connects the receiver and a low-pressure side of the throttle device in the refrigerant circuit; and high-pressure-side and low-pressure-side flow-rate adjustment devices which are located between the respective connection pipes, and which adjust the flow rate of the refrigerant. The receiver is provided in a position which is higher than that of the low-pressure-side flow-rate adjustment device, and potential energy of the refrigerant stored in the receiver is used to facilitate the flow of said refrigerant to the low-pressure-side flow-rate adjustment device.
