  • Patent number: 10955160
    Abstract: An air conditioner includes: a heat source unit including a compressor and a heat source-side heat exchanger; and a plurality of utilization units each including a decompressing device and a utilization-side heat exchanger. The utilization units are connected in parallel to the heat source unit to form a refrigerant circuit. The air conditioner performs a cooling operation using the heat source-side heat exchanger as a condenser and the utilization-side heat exchanger as an evaporator. The air conditioner further includes: a detection sensor that detects a state of air related to a required capacity of each of the utilization units; and a control apparatus that acquires the required capacity of each of the utilization units based on a detection result of the detection sensor.

  • Publication number: 20200363076
    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.
