Estimating the term…
An air-conditioner, an outdoor unit and an refrigeration device each using a refrigeration cycle which can reduce power consumption so as to be highly efficient, which can be operated by a commercially available power source, and which is highly reliable. An air-conditioner comprises a motor and a refrigeration cycle including a compressor driven by the motor, an outdoor heat-exchanger and an indoor heat-exchanger, the motor being located in a motor chamber within a closed container, and refrigerant gas in the refrigeration cycle flows through the motor chamber, wherein the motor has a core of a rotor in which a cage type conductor and permanent magnets magnetized in bipolar state are embedded, and said motor is driven by a commercially available electric power source.
An air-conditioner comprising a motor and a refrigeration cycle including a compressor driven by said motor, an outdoor heat-exchanger and an indoor heat-exchanger, said motor being located in a motor chamber within a closed container, and refrigerant gas in the refrigeration cycle flows through the motor chamber, wherein said motor has a core of a rotor in which a cage type conductor and permanent magnets magnetized in bipolar state are embedded so as to serve as a synchronous motor, and said motor is driven by a commercially available electric power source.
An air-conditioner comprising a motor and a refrigeration cycle including a compressor driven by said motor, an outdoor heat-exchanger and an indoor heat-exchanger, said motor functioning as an induction motor and a synchronous motor of which conductor heating refrigerant and lubrication oil in said refrigeration cycle, wherein during heating operation, said motor is operated as said induction motor so as to start said refrigeration cycle, and thereafter, said motor is operated as the synchronous motor.
An air-conditioner comprising
An outdoor unit comprising a motor, a compressor driven by said motor and an outdoor heat-exchanger, said motor being incorporated in a motor chamber within a closed casing and comprising a scroll compressor, said motor having a core of a rotor in which a cage type conductor and permanent magnets magnetized in bipolar state are provided.
A refrigeration device comprising a motor, a compressor, a condenser, a liquid receiver, an expansion valve and an evaporator, said motor being incorporated in a motor chamber within a closed container, said compressor comprising a scroll compressor including a fixed scroll and an orbiting scroll, said orbiting scroll being rotated by said motor having a core of a rotor in which a cage type conductor and permanent magnets are embedded.
