Study On The Development And Performance Of Modular Wall With The Temperature And Humidity Adjustment Function

With the development of society and the continuous improvement of people's living standards,people's requirements for existing building technology are also constantly improving.As an emerging building structure system,modular building not only can reduce the pollution problems in the traditional construction process,but also has the advantages of smart assembly,simple construction,etc.,in line with the concept of green building.In order to comply with the development requirements of modular buildings,this paper combines the building wall with the semiconductor refrigeration device to develop a new modular functional wall with temperature regulation and humidity control performance.The wall uses a semiconductor refrigeration device disposed inside the wall to adjust and control the air entering the room,and can adjust and control the indoor environment of different seasons,and simultaneously use the solar energy to drive the refrigeration unit and the fan operation saves energy and improves the utilization of the building space.The utilization of building space has realized the functionalization of the building wall.Based on the experimental test platform built in this paper,the experimental and theoretical research on the performance of modular temperature-controlled humidity control wall is carried out.The temperature regulation and humidity control performance of the device under different working conditions were analyzed.The regeneration characteristics of the device during continuous operation were tested and analyzed,and the influencing factors were studied.The test results show that under the summer environment conditions in South China,when the modular thermostat wall has a cooling speed of 4.5m/s at the hot end and a test voltage of 11 V,the maximum cooling capacity of the device can reach 248 W,the inlet and outlet air temperature drops to 8.2°C;under the winter environment conditions in South China,when the modular thermostat wall has a heating speed of 4.5m/s and an input voltage of 14.8V,the maximum heat capacity of the device can reach 1200 W,the maximum temperature rise of the inlet and outlet air can reach 26°C,this reflects the improved temperature regulation of the modular thermostat wall.In terms of humidity control performance,this experiment mainly tests and analyzes the humidity regulation characteristics of the device,the regeneration performance of t he hot end air,and the humidity control efficiency.The experiments were carried out under simulated indoor environmental conditions in the museum,climatic conditions in the rainy season in southern China,and the summer indoor environmental conditions in South China.The test results show that the developed device can meet the corresponding humidity regulation requirements for three different climatic conditions.The maximum humidity control capacity of the device is 2.84g/kg,3.76g/kg,5.59g/kg,and the humidity control range of the device is 1.85g/kg~5.59g/kg,indicating that the device has a good humidity control range and wide adaptability.The theoretical analysis of the heat transfer characteristics of the semiconductor refrigeration system inside the device is carried out,and the calculation model of the temperature regulation performance of the wall is established.The average relative error between the model values of the winter and summer conditions and the experimental values is 4.54% and 6.64%,respectively.The model has good accuracy and provides basic experimental and theoretical basis for the functional application of the wall.
