<p>To provide a low-cost and highly reliable indoor unit and an air-conditioning apparatus having the same by obtaining a dew point temperature at the outlet side without installing a humidity sensor and a dew point temperature detector at the outlet side. An indoor unit 1 includes: an evaporator 1, a blower 1, a suction air temperature detector 6 that detects a suction air temperature at the upstream side of an air flow of the evaporator 3, an outlet air temperature detector 5 that detects an outlet air temperature at the downstream side of the air flow of the evaporator 3, an evaporator inlet fluid temperature detector 14 that detects a fluid temperature at the fluid inlet side of the evaporator 3, an adjustment valve 9 that adjusts a flow amount of the fluid made to flow into the evaporator 3, and a controller 4 that calculates a suction air dew point temperature by suction air temperature information detected by the suction air temperature detector 6 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.</p> |
