In recent years, with the increasing number of construction projects, people's demand for heating, ventilation and air conditioning is also increasing and the technical requirements are more stringent. Therefore, in order to meet people's expectations, we need to optimize and perfect the original technology so that it can adjust the indoor temperature more appropriately to bring real comfortable experience to people. Heating ventilation and air conditioning engineering is the product of the development of modern science and technology. However, due to the emergence of new technology, many engineering construction personnel do not understand the construction process and technology thoroughly, so it will be difficult for people to control the construction quality comprehensively. Therefore, when carrying out the design and installation of heating, ventilation and air conditioning engineering, relevant staff need to have a detailed understanding and study of relevant technologies to master the key points of work to effectively improve its use quality in the later stage and thus improve people's satisfaction with the use of equipment.
