Research on Control Property of Low-temperature Floor Radiant Heating System

Abstract

A new energy-efficient and comfortable heating system, low-temperature floor radiant heating system of floor radiation is increasingly applied to a wide range of housing construction. In the paper, establishing the model of radiant floor heating systems, the effect of outdoor temperature, enclosure structures and heating storage characteristics that influence the indoor air temperature and the enclosure temperature, have been analyzed. The fuzzy-PID controller is chosen as the control radiant floor heating system. Several control strategies such as air-based control, slab-based control, and twoparameter control have been compared. Two-parameter control based on the floor surface temperature and the indoor air temperature is very stable, with high initial investment.
