地板辐射供冷的控制方法

地板辐射供暖和供冷系统的舒适性和节能效果,已经得到人们的认同。采用精确的控制方法来保证室内的温度、地板表面温度并防止地板表面结露是非常重要的。本文根据操纵变量将地板辐射控制系统分为四类,即供水温度控制、供水流量控制、供水温度与流量同时控制和热流量控制,系统阐述了各种控制方法并介绍了两种带除湿的地板辐射供冷控制逻辑。最后介绍了一种地板辐射供冷与置换通风相结合的控制实例。

The Control Methods for Radiant Floor Cooling System

Radiant floor heating and cooling in buildings has long been recognized for both efficiency of delivery of conditioning and for maintenance of comfort. It is important to select a precise control method to maintain a stable room temperature and floor surface temperature and prevent surface condensation. This paper classified various control methods for the radiant floor cooling system according to manipulated variables of supply water temperature control, supply water flow rate control, water temperature plus flow rate control and flux modulation control, and introduced various control methods. Present two Control algorithms of the dehumidification-integrated radiant floor cooling system. At last gived an example of the control method of radiant floor cooling with displacement ventilation.
