Patent ID: 8578727

Claim:
An indoor unit comprising: an evaporator, a blower that supplies air to the evaporator, a suction air temperature detector that detects a suction air temperature in the upstream of the air flow of the evaporator, an outlet air temperature detector that detects the outlet air temperature in the downstream of the air flow of the evaporator, an evaporator inlet fluid temperature detector that detects the fluid temperature in the fluid inlet side of the evaporator, an adjustment valve that adjusts the flow amount of the fluid made to be flowed into the evaporator, and a controller that calculates a suction air dew point temperature from suction air temperature information detected by the suction air temperature detector to calculate an outlet air dew point temperature based on the suction air dew point temperature, the suction air temperature, the outlet air temperature, and the evaporator inlet piping temperature.
