Wherein the constant temperature is the indoor temperature which is balanced in 20 +/-2 ℃ in winter and 26 +/-2 ℃ in summer all the year round, and the people can enjoy a comfortable living environment like spring in four seasons. The constant humidity is 30-70% of the indoor relative humidity balance, and reaches the optimal comfort interval standard of the human body. The air inlet of the fresh air handling unit is constant, no blowing sense exists, and the noise is less than 35 dB. Constant oxygen is replaced and ventilated for 24h, and fresh air is used for surrounding the air all day long. The constant net is that the PM2.5 filtration rate is more than 95 percent, and the indoor carbon dioxide concentration is ensured to be less than 900 ppm.
The microwave sterilization is to irradiate microwaves to the air, and the air is purified and sterilized by utilizing the heat effect and the non-heat effect of the microwaves, so that the purification effect of the five-constant air conditioner is improved. During sterilization, a portion of the heat generated by the heating effect of the microwaves is used for sterilization, and another portion is conducted to the surrounding environment in the form of heat dissipation. The heat dissipated by microwave sterilization can affect the energy consumption of the air purification equipment utilizing the microwave sterilization principle, and heat exchange treatment is needed to collect the energy therein.
The plate heat exchanger is mainly used for heat exchange among different media, so that waste heat is recovered, and the utilization rate of energy is improved. The energy recovery device is commonly used for recovering energy in discharged outdoor air in a fresh air ventilator unit, and reduces energy consumption of an air conditioner.
