Building environment simulation experiment system

Abstract

A building environment simulation experiment system comprises an experimental partition, a left space and a right space. The left space and the right space are divided by the partition. A variable-frequency air conditioner used for simulating indoor environment of consistent normal temperature and indoor humidity is disposed in the right space. A lamp for simulating indoor lighting is further disposed in the right space. A drier, a heater, a blower and a humidifier are disposed in the left space. A heat-flow meter is disposed on one side of the left space of the partition. Temperature sensors are disposed on two sides of the partition. The temperature sensors and the heat-flow meter are all connected with a central processing unit, and the central processing unit is connected with a display. An operator can simulate a required outdoor environment index by only operating devices of the drier, the heater, the blower, the humidifier and the like and simulate an indoor environment index by only operating the frequency-variable air conditioner and the lamp. A thermal conductive coefficient detected under the precisely simulated environment is high in precision, and real performance of materials can be reflected.

Description

technical field [0001] The invention relates to a building environment simulation experiment system, and also relates to a method for detecting thermal conductivity using the building environment simulation experiment system. Background technique [0002] In construction engineering, more and more attention is paid to the thermal insulation performance of building exterior wall materials, which directly affects the energy saving and environmental protection of buildings, but the detection of thermal conductivity of exterior walls has always been difficult. At present, more methods are used to test the thermal conductivity by setting different temperatures on both sides of the exterior wall material, but the heat conduction is not only affected by the temperature difference, but also the humidity of the environment, wind force and how the heat energy is transferred to the exterior wall will affect the thermal conductivity. Therefore, traditional measurement methods can n...

[0002] In construction engineering, more and more attention is paid to the thermal insulation performance of building exterior wall materials, which directly affects the energy saving and environmental protection of buildings, but the detection of thermal conductivity of exterior walls has always been difficult

At present, more methods are used to test the thermal conductivity by setting different temperatures on both sides of the exterior wall material, but the heat conduction is not only affected by the temperature difference, but also the humidity of the environment, wind force and how the heat energy is transferred to the exterior wall will affect the thermal conductivity. detection value, so the traditional measurement method can no longer meet the precise detection requirements
