Title:
AIR CONDITIONER
Document Type and Number:
Japanese Patent JP2023180835
Kind Code:
A
Abstract:
To provide an air conditioner capable of suppressing noise at starting.SOLUTION: An air conditioner 10 includes a cycle which includes an evaporator (indoor heat exchanger 160), a compressor 230, a condenser (outdoor heat exchanger 280), a four-way valve 250, and an expansion valve 240. The air conditioner 10 further includes an evaporation temperature detecting unit 273, a condensation temperature detecting unit 275, a compression ratio calculating unit 213, a setting unit 214, and a control unit 215. The evaporation temperature detecting unit 273 detects an evaporation temperature of an evaporated refrigerant. The condensation temperature detecting unit 275 detects a condensation temperature of a condensed refrigerant. The compression ratio calculating unit 213 calculates a compression ratio calculated from the evaporation temperature and the condensation temperature. The setting unit 214 sets a minimum rotation speed of the compressor 230 on the basis of the compression ratio. The control unit 215 controls to change a target rotation speed of the compressor 230 to the minimum rotation speed.SELECTED DRAWING: Figure 5
