چکیده
In order to reduce the heat transfer between indoor and outdoor environments influence of ambient temperature fluctuation on environment, adding micro-PCM building envelope is one effective means. Micro-PCM can ?intelligently? control by absorbing or releasing during phase change maintain stability. this paper, temperature-adjustable mortar was prepared using with a 25?C, painted surface cement wallboard (300 ? 100 mm) form thermostatic layer cross-section size 300 20 mm. The solar radiation outer simulated an incandescent lamp. performance tested. thermal PCM COMSOL software. Results show that compared ordinary wallboard, when content 40%, maximum inner wall be reduced 5.17?C, time reach delayed 145 minutes. amplitude 1.90?C, instantaneous 22.202 W/m2.

Numerical Study on Improving Indoor Thermal Comfort Using a PCM Wall
A one-dimensional mathematical model was developed in order to analyze and optimize the latent heat storage wall. The governing equations for energy transport were developed by using the enthalpy method and discretized with volume control scheme. The resulting algebraic equations were next solved iteratively by using TDMA algorithm. A series of numerical investigations were conducted in order t...

متن کاملTHERMAL PERFORMANCE SIMULATION OF HYDROPONIC GREEN WALL IN A COLD CLIMATE
The green hydroponics walls are among new kinds of building facades, which receive more attention from architects lately. In addition to the positive effect these walls have in maintaining humidity in arid regions, they also have positive thermal performance in both cold and hot weather conditions. Therefore, they are in the center of designers’ focus for public spaces such as schools. In terms...
متن کاملNumerical simulation of heat and mass transport during hydration of Portland cement mortar in semi-adiabatic and steam curing conditions.
A model that describes hydration and heat-mass transport in Portland cement mortar during steam curing was developed. The hydration reactions are described by a maturity function that uses the equivalent age concept, coupled to a heat and mass balance. The thermal conductivity and specific heat of mortar with water-to-cement mass ratio of 0.30 was measured during hydration, using the Transient ...
