The performance of radiant heating systems (floor heating, ceiling panels) is relatively well documented. Water based systems, where pipes are embedded in the building structure, are now being increasingly used for cooling purposes. Several theoretical studies based on the use of computer simulations have been published, but very little is reported on the actual performance in existing building...

One of the most critical variables in field thermal comfort measurements is mean radiant temperature which typically measured with a standard 150 mm black globe thermometer. This also reference instrument required for assessment heat stress conditions by means well-known Wet Bulb Globe Temperature index (WBGT). However, one limitations this method represented relatively long response time. why ...

to doing this research daily interpolated temperature data from asfezari data base have been used. in order to recognition extreme cold days, the normalized temperature deviation index (ntdi) applied. then the index sorted according to extensive and severity and first 500 days selected for analysis. the geopotential height data extracted from www.esrl.noaa.gov data base. the thickness anomaly c...

The microclimate model ENVI-met (V4) was used for predicting the effects of different systems of planted pergolas on the microclimate of an atrium. The model was firstly validated using experimental data and then used for different cases studies. The microclimate measurements were carried in a real construction project of a hydroponic pergola at Kostakii Campus of the Technological Education In...

drying is one of the most important steps in raisin processing. during this step, initial moisture content decreases up to 15-17% (db) for suitable storage. achieving optimum drying conditions can affect the processing time and improve raisin quality. temperature, air velocity and pretreatment are important factors in the quality of the grape drying process. in this research, the effect of temp...

Many studies have explored outdoor thermal comfort during the last several years, ever since it has been strongly related to human health and well-being. The physiological equivalent temperature (PET) is one of most commonly used indexes. It approved applied within different urban spaces climates. This study a comparative research that importance using mean radiant (Tmrt) in PET assessment by e...
