New description: [New technology field] Especially refers to an air conditioner variant. This new type is related to a control module frequency control module. [Prior Art] With the advancement of technology and the improvement of living standards, the use of 3c products is becoming more and more popular. In the case of air-conditioning units with fairly common usage rates, it has been different from the past. At present, the demand for indoor and ten-internal temperature and the need for energy-saving and carbon-reduction are bound to make the air-conditioning unit in the pursuit of a comfortable environment, and also to be able to balance the effects of environmental protection and energy conservation. As shown in FIG. 1 , the existing AC air conditioning device includes a temperature detector 11 , a preset temperature device 12 , a comparator 13 , a switch 14 , and a compressor 15 , wherein the comparator 13 can be According to the preset temperature of the preset temperature device 12, compared with the temperature detected by the temperature detector 11, when the m·degree is set to the detected temperature, the switch 14 is driven to start the compressor 15 When the set temperature is lower than the detected temperature, the switch 14 cuts off the power supply of the compressor 15 to switch the AC air conditioner to the air supply mode. — In view of the above, the existing parent air conditioning unit has the following disadvantages because the compressor 15 can only be operated at a fixed speed or stopped, and has the following disadvantages: - 1. The air conditioning environment is less comfortable: in order to avoid frequent startup of the compressor 15 And the stop causes the mussel to be broken, so the compressor 15 is turned on when the room temperature is about a first set value (for example, 28 ° C), and the temperature is turned off when the room temperature is lower than a second set value (for example, 25 〇 c). The compressor 15 thus changes the temperature drop at room temperature by 3 M392327, causing the indoor space to become hot and cold and uncomfortable. — 2. High energy consumption: Since the compressor 15 is activated, the refrigerant is fixed at a high-speed helium loop, 'not sufficiently heat-absorbing and dissipating heat', thus reducing energy efficiency, and the compressor 15 has a high current flow from stop to start to high speed. This results in more power consumption. 3. Reduce the service life: Because the speed of the start and stop of the compressor 15 is very different, in addition to the noise generated in the process, the internal mechanical wear of the compressor 15 will also have an impact, thus reducing the compressor I5. The service life of the rotating element.
