Comparative experimental study on floor radiation heating and fan-coil heating

In order to investigate the application effect of low temperature heating system in Chengdu,contrasting experiments have been carried out on floor radiation heating and fan-coil convection heating.The results indicate the temperature and humidity vertical gradient is very small when adopting floor heating,and the radiation heat transfer proportion is large,it's about 59.8%.The effective heating time of floor heating is 2.7 times longer than that of fan-coil heating under the same working condition.The floor radiation heating is comfort and economical saving energy,which provided the basis for its popularization and application in hot summer and cold winter area.
