The invention relates to a radiant cooling system of the technical field of heating ventilation and air conditioning, in particular to an anti-condensation control system and method for the radiation tail end of a grating pipe network. The anti-condensation control system for the radiation tail end of the grating pipe network comprises a measuring unit, a computing control unit and an execution unit, and is characterized in that the output end of the measuring unit is connected with the input end of the computing control unit, the output end of the computing control unit is connected with the input end of the execution unit, indoor environment variables are measured by the measuring unit in real time, the computing control unit receives the real-time data signals of the measuring unit and carries out computing processing, a real-time decision is made according to a control algorithm, control instructions are generated, control signals are output to the execution unit, and therefore anti-condensation control is achieved.

Description

technical field [0001] The invention relates to a radiation cooling system in the technical field of heating, ventilation and air conditioning, in particular to a control system and method for anti-condensation at the radiation end of a grid pipe network. Background technique [0002] With the improvement of people's living standards and the renewal of life concepts, human beings have higher and higher requirements for comfortable life. The radiant cooling and heating system is attracting more and more attention and applications due to its characteristics of uniform indoor temperature distribution, no obvious blowing sensation, no noise, strong cold and heat storage capacity, and small equipment load. [0003] Different from the traditional cooling and heating system that mainly uses convective heat transfer, the radiant cooling and heating system uses radiation heat transfer as the main way to regulate the indoor temperature. During the summer operation, the surface tempera...
