The heating process is opposite in winter. Therefore, the outdoor unit has low temperature in winter, and still needs to absorb heat energy outdoors in such an environment, more electric energy is consumed, and if the outdoor temperature is too low, the heat energy cannot be extracted because the radiating fins are frosted, and the outdoor unit can continue to work only by defrosting. In summer, the outdoor temperature is high, heat is radiated at high temperature, the heat radiation is not smooth, the refrigeration effect is influenced, the energy consumption is increased, and as a result, the effect is poorer when the indoor and outdoor temperature difference is larger.

The larger the indoor and outdoor temperature difference is, the poorer the effect is.
The working principle of the fresh air system is as follows: fresh air is sucked from the outdoor, filtered, and changed into waste gas after being used by breathing, and then is discharged out of the outdoor. In winter, the relative temperature of the sucked air is low, the relative temperature of the discharged air is high, and in summer, the relative temperature is high, so that energy waste is caused, namely, temperature difference energy is accumulated in the waste gas discharged from the indoor. Although the fresh air system has a total heat exchange technology, cold air and hot air alternately pass through the film and heat energy is transferred through the film, the method has the defects of wind leakage of fresh air and waste gas, increase of wind resistance and the like.
