図れる。 During heating operation, the operation selector switch 23
The high output side contact (between a and c) of is closed, and the switch 22 is also closed to form a closed circuit between the second main winding 19 and the positive temperature coefficient thermistor 16. When the main switch 25 is turned on in this state, current flows through the first main winding 18, and further current flows through the auxiliary winding 20 via the starting capacitor 21, and the driving motor 17 is started. At this time,
A voltage is induced in the second main winding 19 by the magnetic field generated in the first main winding 18, and current flows through the positive temperature coefficient thermistor 16 due to this induced voltage. When a current flows through the PTC thermistor 16, the PTC thermistor 16 generates heat, and the refrigerant is heated by the heat generated. Therefore, the heating capacity can be significantly improved.

Then, the current flowing through the PTC thermistor 16 becomes smaller, and the heating force on the refrigerant is reduced. Therefore, the heating capacity can be improved without overheating, that is, without causing an abnormal temperature rise.

流が流れない。 During cooling operation, the switch 22 is opened and, for example, the high output side contact (between a and c) of the operation changeover switch 23 is closed. In this state, when the main switch 25 is turned on, current flows through the first main winding 18, and further current flows through the auxiliary winding 20 via the starting capacitor 21, and the driving motor 17 is started. In this way, the drive motor 17 is operated at high output. In this case, the second
A voltage is induced in the main winding 19 of the switch 22.
Since it is open, no current flows through the positive temperature coefficient thermistor 16.

機１７の高出力運転が行なわれる。 Further, in the cooling operation, the switch 22 is closed, and the low output side contact (between a and b) of the operation changeover switch 23 is closed. In this state, when the main switch 25 is turned on, the first main winding 18
Then, current flows through the auxiliary winding 20, and the drive motor 17 is started. In this case, since the switch 22 is closed, current also flows through the second main winding 19, but the current is small and therefore the second main winding 19
is equivalently ignored. Therefore, the driving electric motor 17 is operated at high output.
しかる後、正特性サーミスタ１６は自己発熱に
よつて高温状態となり、高抵抗を有するようにな

巻線１８および補助巻線２０に電流が流れるよう
になり、その第２の主巻線１９の投入によつて駆
動用電動機１７の低出力運転が行なわれる。 Thereafter, the PTC thermistor 16 becomes hot due to self-heating and has a high resistance. Then, current starts to flow to the first main winding 18 and the auxiliary winding 20 via the second main winding 19, and by turning on the second main winding 19, the driving electric motor 17 is activated. Low power operation is performed.

力を高め、冷房立上がり特性の向上を図り、起動
後の定常運転においては低出力運転によつて最適

のである。 In other words, at startup, the cooling capacity is increased through high-output operation to improve the cooling start-up characteristics, and during steady-state operation after startup, the optimal cooling capacity is achieved through low-output operation to improve the energy-saving effect. This is what we aim to do.

Moreover, by using the positive temperature coefficient thermistor 16 for winding switching during low output cooling operation,
Appropriate capacity control can be performed, and cooling start-up characteristics and energy saving effects can be improved.
