Abstract: A first learning device includes a data acquisition unit and a model generation unit. The data acquisition unit includes the data acquisition unit to acquire, as first learning data, information on a weather forecast for an area where a plurality of outdoor units are installed, information on time, information on a frequency of each of a plurality of compressors included in each of the plurality of outdoor units, information on a low pressure of each of the compressors, and information on a high pressure of each of the compressors; and the model generation unit to generate, using the first learning data, a first learned model for inferring the low pressure and the high pressure from the information on the weather forecast and the information on the frequency.

Abstract: An indoor unit of an air-conditioning apparatus includes a body casing having an air inlet formed in an upper portion of the body casing and an air outlet formed in a lower portion of the body casing; a ventilation passage formed in the body casing; an evaporator provided to a refrigerant circuit, disposed in an inclined manner in the ventilation passage, and covering the ventilation passage such that air freely passes; a main drain pan disposed below the evaporator; and a fan disposed in the ventilation passage. The evaporator is divided into an upper heat exchanger and a lower heat exchanger. A sub-drain pan that receives dew condensation water coming out from a gap of the joint is disposed at a downstream side in a ventilation direction of a joint between the upper heat exchanger and the lower heat exchanger.

Abstract: Provided is an air conditioning apparatus, including a unit main body in which a heat exchanger and at least one blower fan are provided. The heat exchanger is arranged on an upstream side of the blower fan. The blower fan includes an impeller, a motor, and a fan casing. The impeller is a turbofan that sucks air from an upper portion thereof and blows out the air radially outward. A rotation axis of the impeller is directed to a unit height direction. The fan casing has a fan air inlet formed in an upper surface thereof, and has a fan air outlet formed in a lower surface thereof. An impeller air outlet of the impeller is covered by side surfaces of the fan casing.
