A number of homes and small apartment buildings have demonstrated combining a large internal water tank for heat storage with roof-mounted solar-thermal collectors. Storage temperatures of 90 °C (194 °F) are sufficient to supply both domestic hot water and space heating. The first such house was MIT Solar House #1, in 1939.
Cooling load profiles for UFAD systems and overhead systems are different, [12] mainly due to the thermal storage effect of the lighter-weight raised floor panels compared to the heavier mass of a structural floor slab. The mere presence of the raised floor reduces the ability of the slab to store heat, thereby producing for the system with a ...
Underfloor heating and cooling is a form of central heating and cooling that achieves indoor climate control for thermal comfort using hydronic or electrical heating elements embedded in a floor. Heating is achieved by conduction , radiation and convection .
A solar heat collector and radiator is a heat collecting and heat radiating roof structure, designed for building roofs specifically. It was built to be used in conjunction with solar energy and uses a system of air circulation for increased efficiency. [1]
Radiant heating and cooling originated as separate systems but now share a similar form. Radiant heating has a long history in Asia and Europe. The earliest systems, from as early as 5000 BC, were found in northern China and Korea. Archaeological findings show kang and dikang, heated beds and floors in ancient Chinese homes. Kang originated in ...
Al Manzano, founder of A&M Refrigeration Co., cools his hand on the vent fan outlet on an air conditioning unit on the roof of an apartment building in North Hollywood.
With the addition of "cold storage to utilize the excess cooling energy of water generated during off-peak hours, the cooling effects for indoor air during the peak-cooling-load times can be significantly enhanced" and air temperatures may be reduced by 6.6–12.7 °C.
Passive cooling covers all natural processes and techniques of heat dissipation and modulation without the use of energy. [1] Some authors consider that minor and simple mechanical systems (e.g. pumps and economizers) can be integrated in passive cooling techniques, as long they are used to enhance the effectiveness of the natural cooling process.
