Abstract

The invention relates to a method for determining surface temperature change of a radiation plate of a radiation cold supply system in water supply cooling. The method comprises the following steps: influence factors of the surface temperature change of the radiation plate and change ranges of all factors are determined according to actual operation conditions of a radiation cold supply air conditioning system; according to the determined influence factors of the surface temperature change rules of the radiation plate and the change ranges of all the factors, ANSYS software is applied to simulate the surface temperature change conditions of the radiation plate in water supply cooling under different influence factors to obtain sample data; and based on SAS software, a statistic analysis program is applied to perform regression analysis for the sample data to obtain a surface temperature change prediction model of the radiation plate in water supply cooling. The method is higher in accuracy of the prediction result obtained by the regression analysis, is simple in control system, can realize real-time control, and is suitable for residential building heating system control.

Description

technical field

[0001] The invention belongs to the technical field of radiation cooling, and in particular relates to a method for determining the temperature change of a radiation plate surface of a radiation cooling system when supplying water for cooling. Background technique

[0002] Compared with the traditional air-conditioning system, the radiant cooling air-conditioning system has the advantages of good comfort, no blowing sensation, no noise, uniform indoor temperature field distribution, and energy saving. The radiant cooling air-conditioning system realizes the independent control of temperature and humidity, which solves the problem of energy waste caused by the coupling of temperature and humidity. Under the same hot and humid environment, the indoor design temperature can be increased by 1-2Β°C under the premise of using the radiant cooling air-conditioning system and the same thermal comfort of the human body. At present, the supply water temperature of the r...
