AIR CONDITIONER

摘要

PROBLEM TO BE SOLVED: To provide an air conditioner which controls humidity without using a humidity sensor in order to reduce costs. SOLUTION: This air conditioner is provided with a target evaporator temperature determining means S2 for determining ranges Km1 and Km2 of a target evaporator temperature corresponding to a target relative humidity of a room from a temperatureαof the room detected by an indoor sucked temperature sensor, and frequency control means S12, S19 and S6 for controlling operation frequencies of a compressor so that the temperature of the evaporator comes within the target evaporator temperature ranges (Km2<=β
