Air can heat pump, etc., through years of technological evolution

The national hvac refrigeration academic annual meeting held recently in yantai. China construction science research institute of building environment and energy saving dean xu said the hvac is an important professional, and in the field of building energy saving and emission reduction is currently in rapid development, to the effect of energy conservation and emissions reduction cannot be underestimated. Our social total energy consumption about 30% comes from building, hvac system energy consumption accounted for 50% of the total energy consumption for building social total energy consumption by around 15%.

In recent years, our country directly from charcoal burning fire to keep warm, winter heating radiator heating, then to "capillary net radiation heating and cooling", "solar", "air can heat pump", etc., through years of technological evolution, energy-saving effect is remarkable. In jinan, for example, even if only with the capillary network floor heating system "to replace the current radiator, the existing heat source under the condition of without increasing the heating load, the heating efficiency can be significantly improved, in more than 40, ten thousand tons of standard coal saving and reduce carbon dioxide emissions more than 100 100 tons. Xu thinks, at present people understanding of hvac energy conservation and emissions reduction potential of the insufficient still. The current government as the leading factor, enterprise as the main body, the whole society together to promote the new pattern of energy conservation and emissions reduction, the hvac industry is the development of new opportunities.
