Abstract

PURPOSE: To estimate the temperature of the outside air and the relative humidity of a room and dispense with an outside temperature sensor, by providing a low-pressure coolant temperature sensor, a high-pressure coolant temperature sensor and a temperature sensor which detects the difference in the temperature of heat-exchanged air between an inlet port and an outlet port.
CONSTITUTION: In cooling, a coolant gas compressed to high pressure and temperature by a compressor 1 is condensed by an outside heat exchanger 2, changed to low pressure and temperature by an expander 3, evaporated by an inside heat exchanger 4 in the room R and returned to the compressor 1. The temperature sensor 7 is provided at the inlet pipe A to the inside heat exchanger 4 to measure the inlet temperature of the coolant to estimate the cooling capability. The saturation temperature of the high-pressure coolant is estimated by the inside high-temperature coolant temperature sensor 10. The quantity of the outside heat exchange is estiminated to determine the temperature of the utside air. The relative humidity of the room is determined from the cooling capability and the difference in the temperature of the heat-exchanged air between the inlet and outlet ports.
