Air conditioner
专利汇可以提供Air conditioner专利检索，专利查询，专利分析的服务。并且PURPOSE: To enable to stop operation quietly without anxiety to users at the operation stop time of space cooling and heating by providing such a function to a motor driven compressor that a pressure reducing device is fully closed in space cooling operation and fully opened in space heating respectively at the stop time of two blowers and simultaneously a motor-driven compressor is stopped after its rotating speed is reduced to a specified value.
CONSTITUTION: When space heating operation is stopped by manipulation of an operation/stop switching 13 at point A, pulses driven by a stepping motor are emitted by a microcomputer 9 to fully open an electronic expansion valve 6 at terminals OUT 10a W OUT 10d and simultaneously indoor and outdoor blowers 8, 7 are stopped respectively and at the same time frequency of a motor for a compressor is slowly reduced by an inverter part 16. On the other hand, at the operation stop time of space cooling pulses, driven by the stepping motor, which are emitted at terminals OUT 10a W OUT 10d of the microcomputer 9 to fully close the electronic expansion valve 6 in response to manipulation of operation/stop switch 13 and at the same each blower 7, 8 is stopped and the compressor 2 is stopped after its rotating speed is reduced to a specified value.
