[0001] The utility model relates to air conditioning throttling technical field, specifically relates to a throttling system of energy -conserving air conditioner. BACKGROUND

[0002] The throttling method commonly used by air conditioners includes outdoor unit throttling and indoor unit throttling. Outdoor unit throttling is achieved by controlling the work amount of the outdoor unit to save energy. When the indoor temperature reaches the required temperature, the outdoor unit enters the throttling state, reduces energy consumption, improves air conditioning efficiency, and ensures the stability and energy saving effect of the air conditioner. Indoor unit throttling is used to adjust the temperature and humidity in the room by controlling the flow of refrigerant passing through the interior, thereby reducing energy waste.

[0003] In an air conditioning system, the throttling devices of the indoor unit and the outdoor unit cannot be used simultaneously. The indoor unit throttling device is mainly used to adjust the refrigerant flow of the indoor unit, while the outdoor unit throttling device is used to adjust the refrigerant flow of the entire system. If they are used simultaneously, it may cause system confusion, affecting the refrigeration effect and system stability.

[0004] In the prior art, a variable frequency compressor is also used to achieve the purpose of throttling, completely replacing outdoor unit throttling and indoor unit throttling. However, the variable frequency compressor has the following defects:

Since the variable frequency compressor is generally used in fields requiring a pure gas environment, such as pharmaceutical and food processing industries, it is easily affected by pollutants during use, resulting in damage to the machine or failure to work normally.

Since the motor and controller used by the variable frequency compressor have relatively advanced technology and structure, the noise generated during operation is also relatively large, causing certain noise interference to the surrounding environment.
