The main indoor environmental characteristics in the commercial field are that the overall indoor space is relatively closed. The population is relatively dense. The ventilation conditions are relatively poor; Due to the actual drawbacks such as low oxygen content and poor air quality, the central fresh air air conditioning system of the building must also be in a long-term working state. Commercial heat recovery rotors are mainly used in conjunction with the fresh air system of central air conditioning. Their core function lies in recovering the cold and heat energy in the indoor recovered air, and then pre-treating the temperature and humidity of the outdoor air (cold/hot) before sending it into the room, so as to reduce the direct impact of the outdoor air temperature and humidity state on the indoor temperature and humidity. At the same time, it reduces the energy consumption required for cooling and heating the fresh air, so as to achieve the goals of energy conservation, emission reduction, energy reduction and consumption reduction.
