Document Type and Number:
WIPO Patent Application WO/2015/140874
Kind Code:
A1
Abstract:
Provided is an air conditioning device capable of suppressing the occurrence of disproportionation reactions (autolytic reactions) when HFO1123 refrigerant or a refrigerant mixture containing HFO1123 is used. This air conditioning device comprises a control device (40) that controls at least one of the operational frequency of a compressor (3), the amount that an expansion valve (7) is opened, and the flow rate of a blower that blows air to a heat source side heat exchanger (9), so that the temperature and pressure of the refrigerant being discharged from the compressor (3) does not exceed a threshold value.
