This paper introduces the research on the heat transfer model of the buried pipe radiant floor, including the semi-analytical model, the numerical model and the simplified model (RC model, transfer function model). At present, the energy consumption or room thermal comfort The commonly used methods of sexual simulation and the commonly used computer simulation software are compared. The application characteristics of two simulation softwares, Energy Plus and TRNSYS, are analyzed and compared in the simulation of buried floor radiant system. The classification of buried tube floor radiation system Control strategy and comparative analysis of the advantages and disadvantages of various control strategies; cites the domestic and foreign research on the combination of buried floor radiant system and ground source heat pump system, points out that the combination of radiation system and ground source heat pump system can improve the energy efficiency of heat pump unit , To improve the soil thermal balance and reduce the energy consumption of the system and so on. According to the domestic and foreign researches on the joint operation of the floor radiant and ventilation dehumidification system, the necessity of adding a ventilation and dehumidification system is pointed out. The ground source heat pump system, System and ventilation and dehumidification system of the three joint operation of the system form, and from the system optimization From the angle of view, this paper puts forward two ways to combine buried pipe floor radiation system and ventilation dehumidification system.
