Embodiment Construction

[0021] Below, the substantive features and advantages of the present invention will be further described in conjunction with examples, but the present invention is not limited to the listed examples.

[0022] see figure 1 As shown, the radiant cooling system of the present invention includes a radiant plate, a plate heat exchanger 4 connected to the circulating water circuit of the radiant plate, wherein the water inlet of the plate heat exchanger 4 is connected to a water outlet of the water distributor, The other water outlet of the water separator is connected to the water inlet of the fresh air unit, and the water outlet of the chiller is connected to the water inlet of the water separator. The water separator transfers the water of the chiller to the plate heat exchanger and the fresh air unit for heat exchange; the plate heat exchanger Heater 4 and the water return port of the fresh air unit are respectively connected to the two return water inlets of the water collector...

Abstract

The invention relates to a method for determining the radiant panel surface temperature change of a radiant cooling system when water supply is started. The method comprises the following steps: determining the influence factors of the radiant panel surface temperature change and the change range of each factor according to actual operating conditions of the radiant cooling air conditioner system; using an ANSYS software to simulate the radiant panel surface temperature change condition when the water supply is started under different influence factors according to the determined influence factors of the radiant panel surface temperature change and the determined change range of each factor, and obtaining sample data; based on an SAS software, carrying out regression analysis by utilizing statistic analysis program sample data, and obtaining a prediction model for the radiant panel surface temperature change when the water supply is started. According to the method, the prediction result obtained through regression analysis is relatively high in accuracy, the control system is simple, real-time control can be realized, and the method is applicable in 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 water supply is turned on. 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 1-2°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 rad...
