Comparison of Thermal Comfort by Radiant Heating and Convective Heating
Currently, convective heating with a heat-pump system, which has high energy efficiency, is popular for room heating. However, it is possible that energy savings using convective heating can be further improved using heat pumps that service both occupied and unoccupied spaces. Moreover, convective heating increases vertical temperature gradients in a room; thus, it is hard to say whether occupa...
متن کاملPerformances of Low Temperature Radiant Heating Systems
The low temperature radiant systems are very complex because they involve different mechanisms of heat transfer: heat conduction through the walls, heat convection between the heating panel and the indoor air, heat radiation between the heating panel and the surrounding areas, and the heat conduction between the floor and the ground. The main essence of the low-temperature air systems is to pro...
متن کاملThe application of radiant heating in the clinical laboratory.
Since Priestley utilized the radiant energy of the sun with his burning glass in his famous experiment of 1774, the method has fallen into disuse and the chemist has accepted the water-bath, the hot-air oven, and the furnace as the standard tools for evaporation, drying, and combustion. The boiling water-bath is used for evaporating solutions or drying solids which decompose at temperatures sli...
متن کاملOptimization of Transient Heater Settings to Provide Spatially Uniform Heating in Manufacturing Processes Involving Radiant Heating
This article presents an optimization methodology for finding the heater settings that provide spatially uniform transient heating in manufacturing processes involving radiant heating. Equations governing the transient temperature and temperature sensitivity distributions over the product are first derived using an infinitesimal-area technique and then solved numerically to calculate the object...
متن کاملModeling and optimal design of ground air collector for heating in controlled environment greenhouse
A mathematical model is devised to study the thermal behavior of a greenhouse while heating with a ground air collector (GAC). A computer program based on MatLab software has been used to predict the plant and room temperatures as a function of various design parameters of the ground air collector. Extensive experiments have been conducted during December 2000 to March 2001 for an even span gre...
