Embodiment Construction
[0024] Referring to Figure 2, the circulation system in this embodiment is set up according to the structure of a conventional fixed-frequency air conditioner. The heat exchanger and the indoor cross-flow fan constitute the indoor unit.
[0025] As shown in FIG. 2 , in this embodiment, in order to achieve strong heat, a high-power auxiliary electric heating device is provided in the indoor unit, and the electric heating power of the high-power auxiliary electric heating device is 0.9 to 1.4 times the rated cooling capacity of the system. For example, for a 2HP fixed-frequency air conditioner, the rated cooling capacity of the system is 5000W, and the heating capacity of the system heat pump is 5500W. For this reason, the electric heating power of the high-power auxiliary electric heating device to be set is 4500W-7000W. Therefore, the total heating capacity of the system is 10000W-12500W, which is equivalent to 5HP. Obviously, the heating capacity of the air conditioner is 2-2...
