Title:
AIR CONDITIONING SYSTEM, CONTROL METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2017/002618
Kind Code:
A1
Abstract:
An air conditioning system comprises: an air conditioning system main unit comprising a compressor to compress gas refrigerant, an indoor heat exchanger to radiate the heat of condensation by liquefying the compressed gas refrigerant, an outdoor heat exchanger to gasify the liquid refrigerant by absorbing the heat of evaporation, a pressure sensor to detect the intake pressure of refrigerant to the compressor, and an outdoor heat exchanger temperature sensor to detect the temperature of the outdoor heat exchanger; a saturation temperature calculation unit to calculate the intake pressure saturation temperature from the intake pressure; and an operation control unit to determine whether countermeasures for frost adhering to the outdoor heat exchanger are required on the basis of the intake pressure saturation temperature and the outdoor heat exchanger temperature.
