A set of calculation method for calculating the cooling load of radiant cooling room is described. Based on the principle of thermal equilibrium, this algorithm fully considers various types of heat gain and heat transfer modes in radiating cooling room, especially radiative heat transfer, and establishes radiation supply Cold room mathematical model lists the heat balance equation of the inner walls of the room, the heat balance equation of the radiation plate surface and the heat balance equation of the air. Through the experimental verification, it is found that the theoretical calculated values of each operating point agree well with the experimental values, which can provide a reference for the calculation of cooling load of radiating air-condition cooling room.
