Description
Technical Field
The invention belongs to the field of radiant heat environment testing, and particularly relates to a device of a non-uniform radiant heat environment test bed and a using method thereof.
Background
In controlling an indoor hot air environment, an air conditioner is generally used to control the temperature, humidity and cleanliness of air. From the viewpoint of comfort, in recent years, radiation cooling and radiation heating for controlling the surface temperature of floors, ceilings, walls, and the like have begun to spread. The method of controlling the indoor environment by radiation has many advantages, such as that the heat of radiation heating is directly transmitted and received with the human body, the air temperature can be relatively reduced, thereby realizing many advantages of energy saving, more uniform indoor temperature distribution, and enhanced human comfort. For analysis of radiation cooling and heating, in a study of the paper "radiation を using a した indoor hooked environment adjusting technique に Seki する (study of indoor environment adjusting technique using radiation)", a radiation environment lab was designed to study how to calculate the amount of heat released by a floor during heating of the floor and how to prevent condensation during cooling of the floor.
The paper takes the measure of developing a radiant environment test chamber of 3600 x 2700 x 3150mm in length x width x height, and directly controlling the surface temperature of the floor, wall and ceiling of the test chamber by hot and cold radiant panels. In order to fix the radiation plate on the inner wall of the laboratory, 40mm pillars were provided at 45.5mm intervals. The radiation plate was fabricated by overlapping 3 parts of a bamboo-stone-like combination of wood, an omega-shaped aluminum plate, and a cross-linked polyethylene pipe (8.5 mm in outside diameter and 6.0mm in inside diameter). In addition, a black-coated aluminum tape is attached to the surface of the radiation panel. The chamber is arranged up and down in the laboratory, wherein the cross-linked polyethylene pipe is stored in the lower chamber, and the effects of floor refrigeration and floor heating can be simulated. In addition, 2 wall surfaces in 4 wall surfaces are divided into 3 parts, temperature control is carried out according to system requirements, and parts with low heat insulation performance such as windows can be reproduced, so that the influence of outdoor environment on indoor environment can be reproduced. In addition, an air conditioner is arranged indoors and used for controlling the indoor air temperature, and the effects of cold air refrigeration and warm air heating can be simulated. The control system of the laboratory is as follows: the system is divided into a 1 st side and a 2 nd side; on the 1 st side, the temperature in the 2 nd side pipe is detected, and the cold and hot water inflow rate from the heat source to the heat exchanger is controlled through a three-way valve, so that the temperature of the cold and hot water in the radiation plate is controlled; on the 2 nd side, the circulation of the cold and hot water with set water temperature in the cold and hot water radiation plate is controlled by a heat exchanger; in addition, the hot water system is 2 systems, and can be controlled at high temperature and moderate temperature.
Although the expected purposes of calculating the heat released by the floor during heating of the floor and how to prevent condensation during cooling of the floor can be achieved by the radiant environment test chamber, the size of the test chamber (fabricated room) is 3600 x 2700 x 3150mm, the test chamber is large in size and high in price, and the test chamber has no universality for other researchers to carry out related experiments; the air conditioner of the laboratory is installed on a ceiling, only has the effect of upward air supply, and is not suitable for researching the influence of different air supply modes such as replacement ventilation, side air supply, air supply of a diffuser and the like on the thermal environment of the laboratory; the surface temperature of the floor surface, the wall surface and the ceiling surface of the test room is directly controlled by the cold and hot water radiation plate, but the manufacturing and installation processes of the cold and hot water radiation plate are complicated; the temperature of 6 surfaces of the laboratory is controlled by a water system, so that the system is large, the operation process is complex, and the problems of water leakage and the like are inevitable; 2 wall surfaces in 4 wall surfaces of the test room are divided into 3 parts, temperature control is carried out according to system requirements, parts with low heat insulation performance such as windows and the like can be reproduced, so that an environmental test room with influence of outdoor environment on indoor environment is reproduced, but the room type is the simplest room type, if different room types such as a skylight and a French window exist, rearrangement and installation are needed, and time and labor are wasted due to a water system, and the test room is not convenient; one wall surface of the test room is divided into 3 parts at most, 2 different temperature distributions are achieved, the distribution positions are fixed, and if the uneven radiant heat environment with overhigh or overlow local temperature is researched, the test room cannot meet the requirements. There is therefore a great need for an improved test rig that can simulate a non-uniform radiation environment.

1) cold water or hot water is introduced into the coil pipe (11) and forms circulation with an external cold water source/hot water source, so that the temperature of the concrete module base (1) is controlled and ground refrigeration and ground heating are simulated;
2) the external power supply supplies power to the heating module (35), the heating module (35) is electrified to generate heat to heat the corresponding grid (3), and the local radiation temperature of the grid (3) can be adjusted by adjusting the temperature of the heating module (35);
3) the circular open end of the square pipe fitting (32) of the sky circle is connected to an external fan coil pipe through an external air pipe, cold air/hot air sent out by the external fan coil pipe enters the inner cavity of the square pipe fitting (32) of the sky circle through the circular open end, the square open end of the square pipe fitting (32) of the sky circle enters the test bed through the return air inlet (38) and the return air inlet (38) is selected according to experimental requirements to simulate different air supply forms, and therefore humidification, cold air refrigeration or hot air heating under different air supply forms are achieved.
10. The method of using a non-uniform radiant heat environment test stand as defined in claim 9, wherein:
When a radiant heat environment experiment is carried out, each grid (3) can be independently set into a temperature control partition, or adjacent grids (3) can be set into the same temperature control partition, and different temperature settings are carried out on different temperature control partitions, so that a non-uniform heat radiation environment is formed.
