Non-uniform radiant heat environment test bed and using method thereof

Abstract

The invention discloses a non-uniform radiant heat environment test bed which comprises a concrete module base (1) and a frame (2). The horizontal cross section of the concrete module base (1) is square, and a loopback coil pipe (11) is buried in the concrete module base (1) along the horizontal plane; the frame (2) is arranged on the concrete module base (1), and the frame (2) and the concrete module base (1) form an approximately cubic test bed; other five surfaces, except the bottom surface, of the frame (2) are respectively arranged to be of grid structures, a pipe fitting (32) with a round top and a square bottom is fixedly arranged on at least one grid (3), and convex electric heating radiation plates (33) are fixedly arranged on the other grids (3). The invention further provides ausing method of the test bed. The non-uniform radiant heat environment test bed can be used for a thermal environment evaluation test, especially a test in a non-uniform radiant heat environment.

Description

technical field [0001] The invention belongs to the field of radiant heat environment testing, and in particular relates to a device for a non-uniform radiant heat environment test bench and a method for using the same. Background technique [0002] When controlling the indoor hot air environment, air conditioners are usually used to control the temperature, humidity and cleanliness of the air. From the viewpoint of comfort, in recent years, radiant cooling and radiant heating for controlling the surface temperature of floors, ceilings, walls, etc. have come into widespread use. The method of controlling the indoor environment through radiation has many advantages. For example, the heat of radiant heating is directly transmitted and received by the human body, which can relatively reduce the air temperature, thereby achieving energy saving, more uniform indoor temperature distribution, and enhanced human comfort. In order to analyze radiative cooling and heating, in the pap...

Problems solved by technology

[0004] Through this radiation environment test room, although the expected purpose of calculating the heat released by the floor during floor heating and how to prevent condensation during floor cooling can be achieved, the size of the test room (prefabricated room) is 3600*2700*3150mm, which is huge , the price is high, and it is not universal for other researchers to conduct related types of experiments; the air conditioner in this laboratory is installed on the ceiling, and only has the effect of upward air supply, and is not suitable for research on displacement ventilation, side air supply, and diffuser air supply. The influence of different air supply forms such as wind on the thermal environment of the laboratory; the laboratory directly controls the surface temperature of the floor, wall and ceiling of the laboratory through the hot and cold radiant panels, but the production and installation of the hot and cold radiant panels The process is complicated; the temperature of the 6 surfaces of the laboratory is controlled by the water system, the system is huge and the operation process is complicated, and problems such as water leakage are inevitable; 2 of the 4 walls of the laboratory are divided into 3 parts, according to the system requirements Temperature control can reproduce parts with low heat insulation performance such as windows, so as to reproduce the impact of the outdoor environment on the indoor environment. However, this is the simplest type of room. If there are different room types such as skylights and floor-to-ceiling windows , you need to rearrange the installation, and because it is a water system, it is time-consuming and laborious, and it is not convenient enough; one wall of the laboratory can be divided into 3 parts at most, to achieve 2 different temperature distributions and the distribution positions are fixed. If the local temperature of the study is too high or too low Inhomogeneous radiant heat environment, the test room does not meet the requirements
