People optimize the engineering technology of heating, ventilation and air conditioning scientifically and reasonably in order to improve the ability to cope with the change of temperature, which can create a better living atmosphere for the residents. With the continuous development of modern society, people have very high expectations on various convenient technologies. People have been constantly thinking of how to optimize the engineering technology of heating, ventilation and air conditioning scientifically and reasonably. Therefore, in the early stage of technical design, people's needs should be taken as the base point to optimize various technical parameters to better improve the quality of subsequent heating,
