Phenomenon；Reduction is leaked out loss, energy saving 2% or more and extension air hose service life (based on 25 years).It calculates as follows:
(1) refrigeration duty value 6300*2%=126KW, 126*3600*24=10886400KJ save electricity 1088640/ daily
3600=3024 degree 3024*0.8=2419 member；
(2) thermic load value 2800*2%=56KW, 56*3600*24=4838400KJ saves electricity 4838400/ daily
3600=1344 degree 1344*0.8=1075 member；
(3) 2419*180+1075*180=628920 member is saved every year；
(4) it reduces coal to calculate, 1 ton of standard coal generation is equivalent to 3000 degree of electricity, and 1 ton of standard coal generates CO2:2.7 tons, 1 year
CO2:(3024+1344 is generated less) * 180*2.7/3000=707.6 (ton), CO2:25* was generated less in service life in 25 years
(707.6=17690 ton).
Summary: it can reduce by 1.77 ten thousand tons of CO2 discharges, save 1597.3 ten thousand yuan of cost of use.
4, by using this techniques save energy, operating cost, environmentally protective, respective country green building number are reduced
It calls together, obtains the consistent favorable comment of society；Meanwhile the high evaluation of Party A, management have been obtained, social benefit is significant.
