Title:

AIR CONDITIONER

Document Type and Number:

WIPO Patent Application WO/2015/083399

Kind Code:

A1

Abstract:

In the present invention a compressor (3), a condenser, a throttle device, and an evaporator are connected to form a refrigerant circuit, and when a large amount of refrigerant is circulating in the refrigerant circuit, an intake degree-of-superheat control is performed, whereby the throttle device is operated on the basis of the intake temperature of the refrigerant drawn into the compressor (3). When a small of amount of refrigerant is circulating the intake degree-of-superheat control is performed until the refrigeration cycle stabilizes, and after the refrigeration cycle has stabilized a discharge degree-of-superheat control is performed, whereby the throttle device is operated on the basis of discharge temperature of the refrigerant discharged from the compressor (3). Thus, an efficient air conditioning operation can be performed regardless of the amount of refrigerant circulating in the refrigerant circuit.
