central heating- a heating system in which air or water is heated at a central furnace and sent through the building via vents or pipes and radiators gas heat- heating system that burns natural gas panel heating- heating system consisting of wall or floor or baseboard or ceiling panels contain...
Apparatus for distributing uniformly a mass flow of air to a heater, for distributing heat from the heater uniformly into the air flow thereby uniformly cooling the heater surfaces and for redistributing the mixed and heated air flow over a wide area at the location where the heated air enters...
In addition, an air cooling fin was designed and integrated into a bipolar plate as a part of a power stack in order to dissipate the excessive heat and maintain the operating temperature at 80°C or less. The results show that cooling fin design can produce effective cooling mechanism for ...
The present forced-air heat exchange system has a solar collector through which air is circulated by a blower to the air inlet of a heat exchanger. The heat exchanger has an air outlet connected to a recirculation duct leading to the air inlet of the blower. A recirculation damper in this...
The ratio of heat losses by conduction and by evaporation from any water surface It is shown that the process of evaporation and diffusion of water vapor from any water surface into the body of air above it is exactly similar to that of the conduction or "diffusion" of specific heat energy...

Although prior studies have proposed that helix angles less than 90° will provide superior heat transfer per unit pumping power, no data have been reported for flow in circular tubes. The present work reports the heat transfer and friction characteristics for air flow with three helix angles (...
5. Locate an air-release valve and an expansion tank at the highest point in the system. 6. All pipes should be insulated. 7. Avoid the use of L’s and reducers as much as possible. 8. If a heat source is added to back up the collectors, the sensor to control it should be loca...
