AIR CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2014/061130
Kind Code:
A1
Abstract:
An air conditioner (1): comprises a refrigerant circuit (10) configured by connecting a plurality of indoor units (4a, 4b) to an outdoor unit (2); and further comprises a capacity control means (81), and a target refrigerant variable temperature means (84). The capacity control means (81) controls the air conditioning capacity of the outdoor unit (2) in such a manner that the evaporation temperature or condensation temperature of a refrigerant in the refrigerant circuit (10) attains a target evaporation temperature or a target condensation temperature. The target refrigerant variable temperature means (84) performs slow speed variable control in which the target evaporation temperature or target condensation temperature is changed according to the temperature difference between the indoor temperature and a set temperature, and if the temperature difference exceeds a threshold temperature difference, and the number of indoor units (4a, 4b) in operation has increased, the target refrigerant variable temperature means (84) performs rapid variable control in which the target evaporation temperature or target condensation temperature is forcibly changed to a rapid tracking evaporation temperature or a rapid tracking condensation temperature.
