  • Publication number: 20240133378
    Abstract: A scroll compressor includes a housing and a compression mechanism. The compression mechanism includes a compression chamber. The housing includes an intermediate pressure chamber into which refrigerant having an intermediate pressure is introduced from an external refrigerant circuit. The intermediate pressure is higher than a suction pressure of refrigerant drawn into the compression chamber and lower than a discharge pressure of the refrigerant discharged from the compression chamber. The intermediate pressure chamber and the compression chamber in a process of compression are connected to each other by an injection passage. The injection passage includes a muffler.

  • Publication number: 20230243361
    Abstract: A blower includes a blower fan, a direct current motor, and a motor controller. The direct current motor rotationally drives the blower fan. The motor controller controls the direct current motor. In controlling the direct current motor, the motor controller uses a control method selected out of a plurality of control methods having characteristic curves that incline differently from one another and intersect one another. Each of the characteristic curves represents an air volume versus static pressure relationship of the blower fan.

  • Patent number: 11506201
    Abstract: The distance between openings of two supply passages that are closest to an accommodating recess is less than the distance between openings of two injection ports that are closest to compression chambers. This configuration minimizes the volume of the space in the accommodating recess between a check valve and the two supply passages, unlike a case in which the distance between the openings of the supply passages that are closest to the accommodating recess is greater than or equal to the distance between the openings of the two injection ports that are closest to the compression chambers. This reduces the flow rate of refrigerant that flows into the accommodating recess from the compression chambers in a compression process through the injection ports and the supply passages.

  • Patent number: 11486395
    Abstract: A flange is held by a peripheral wall of an intermediate housing member and a peripheral wall of a motor housing member. In this state, bolts are passed through the intermediate housing member and the flange and are threaded to a peripheral wall of the motor housing member, thereby integrally fixing a shaft support housing member to the intermediate housing member and the motor housing member. Thus, the shaft support housing member sufficiently receives the fastening force of the bolts. Vibration of the shaft support housing member is therefore easily suppressed. The intermediate housing member includes a peripheral wall. Thus, the intermediate housing member has a higher stiffness than in a case in which the intermediate housing member does not have the peripheral wall.
