In winter, the space interlayer is in a stable state in a closed state, and the overall thermal resistance of the building roof is as follows:
according to the requirements of the EPS external thermal insulation structure mode of the reinforced concrete roof in the table A.0.6 serial 3 in the rural residential building energy-saving design standard (GB/T50824-2013), the thermal resistance of the roof is as follows:
according to calculation, the thermal resistance of the roof structure is greater than the thermal resistance of a roof in the energy-saving design standard of rural residential buildings (GB/T50824-2013), and the use requirement is met.
2. Summer conditions
Of building roofs under conditions of heat exchange and ventilation in summer
In summer, the heat storage and ventilation state is dynamic, and heat exchange is performed indoors and outdoors through ventilation, so that heat storage and ventilation calculation is required.
Total heat capacity of heat accumulator
The calculated value was 7.67X 107Units J/DEG C;
radius of indoor equivalent heat accumulator
The calculated value is 0.2, unit m;
effective heat diffusion coefficient of equivalent heat storage
The calculated value was 6.43X 10-7The unit m;
time constant
The calculated value is 18.4 in h;
number of convection heat transfer
The calculated value was 6.94;
fourier time constant eta ═ R2A calculated value of 17.54 in units of h,/κ/3600;
delayed phase of indoor air temperature compared to outdoor air temperature
ratio of indoor air amplitude to outdoor air temperature amplitude
in the calculation formula:
through calculation, the temperature delay time is 0.45h, the temperature attenuation multiple is 3.75 times, and the summer temperature environment of a room can be remarkably improved.
In conclusion, the invention effectively improves the problem of roof overheating in summer and simultaneously improves the heat preservation and insulation efficiency of the roof in winter; meanwhile, the invention can fully utilize natural lighting in the daytime to improve the indoor lighting condition, convert sunlight in the daytime into chemical energy of the battery and convert the sunlight into electric energy at night to provide indoor lighting.
