Summer solar savings to winter seasonal heating has become reality

Now everyone is talking about environmental protection and energy saving, how nature of energy are reasonable utilization, is key. Summer heat storage by technology, to supplement with solar heating in winter, it sounds weird, but the new "cross-season regenerative solar heating system" can use solar direct heating. Yesterday, in Jinzhou City construction science and technology achievement appraisal, this technology has been recognized by the experts, and municipal construction and technological achievement appraisal and Promotion Committee's identification.

Not just civil buildings need more energy, manufacturers need to reduce energy consumption. Early in 2006, the province will require the phasing out the province Enterprise 4 tons of coal-fired heating boiler. Against this background, the savings in energy use for enterprise plant way of solar heating to start brewing. Jinheng auto safety system co., Ltd. of integrated plant became the first piece of the "experimental plots". Reporters on the scene to see that the construction area of 7600 square meters of factory buildings, the heating area is 23000 m2, heating has always been a challenge. Now the factory has adopted this kind of "cross-season regenerative solar heating system".

Solar Collector area in the plant outside of open space, consisting of several hundred pieces of collector pieces, absorb the Sun's heat. This system is also advanced in stores summer heat for winter heating. A collector area of hot water into underground part energy storage area, heat release to regenerative materials (equipped with a certain proportion of soil and gravel) realization of thermal storage. If winter solar radiation does not meet the heating load, start the underground heat storage district, pumped material to heat circulating water release in order to meet the heating requirements. If extreme weather or night heating load is large, then start the auxiliary heating equipment to recycle water heating. To the plant, for example, the use of traditional methods of heating, the plant's average temperature is 8.5 ℃. Last winter with solar heating renovation, workshop of temperature stability at 12 ° c-15 ℃. Operational costs far less than other heating methods, a heating period for the Save heating costs 60 million, a reduction of 920 tonnes of coal and reduce carbon dioxide emissions 2409 tons.

It is understood that the use of solar energy in this large area of heating in the province are rare. This "cross-season regenerative solar heating system" has achieved the domestic advanced level. Its performance q/JSX001 — 2010 enterprise standards and user requirements, the environmental protection and energy saving heating mode will in future have a greater development space special indeed city reconstruction.
