Abstract: An air conditioning unit that blows out temperature-controlled air to a front side indoors, includes: a fan; a rectangular casing in which the fan is disposed; and an air passage forming member that is disposed on an air-flow downstream side of the fan and that forms an air passage having a circular cross-sectional shape. The rectangular casing has a first side, a second side, a third side, and a fourth side when viewed from a front direction of the casing. The first side is parallel to the second side, and the third side is parallel to the fourth side. A smaller one of a first distance between the first side and the second side and a second distance between the third side and the fourth side is no greater than 2.5 times a diameter of a cross section of the air passage.

Abstract: An outdoor unit for an air conditioning device includes an outdoor unit main body, a heat exchanger, a fan provided in an upper part of the outdoor unit main body, the fan blowing out the air taken in from a side surface of the outdoor unit main body upward, a ventilating member surrounding an outer circumference of the fan and forming a blow-out port, and an electric component unit accommodated in the outdoor unit main body and arranged in an opening portion between one side end portion and the other side end portion of the heat exchanger, wherein the electric component unit is provided so as to cross over a lower end of the ventilating member in the up and down direction, and on the upper side than the lower end of the ventilating member, the electric component unit is arranged on the horizontally outer side than the ventilating member.

Abstract: The present invention provides a heat source unit capable of being used in either an air conditioner for switchable cooling and heating operation or an air conditioner for simultaneous cooling and heating operation. An air conditioner principally includes one heat source unit, a plurality of utilization units, and a connecting unit provided for each utilization unit. The heat source unit uses water as the heat source, and principally includes a compressing means, a main heat exchanger, a first switching means, a main refrigerant switching means, an auxiliary heat exchanger connected in parallel with the main heat exchanger, a second switching means, an auxiliary refrigerant switching means, and a liquid receiver. The auxiliary heat exchanger is capable of switching between functioning as an evaporator and a condenser, by the second switching means.

Abstract: The present invention reduces the size of an outdoor refrigerator unit of the type that draws in air from a lateral face, exchanges heat with the air, and blows the air out of a top face while ensuring that the electrical equipment box has sufficient volume and suppressing the increase in the air flow resistance. The air conditioning system outdoor unit is of the type that draws in air from air inlets provided in the rear panel and a pair of side panels of a casing, exchanges heat with the air, and blows the air out through an air outlet provided in a top panel. The outdoor unit is provided with an axial fan and an electrical equipment box arranged inside the casing. The electrical equipment box is arranged inside the casing and has a first box part that is provided below the axial fan and a second box part that is provided below the first box part and has a larger surface area in a plan view than the first box part.
