s some local acid rain, the fly ash question assumes day by day the serious potential, has brought the very tremendous influence to the ecological environment and the sustainable development. In hottest summer, if to passes the airconditioning system to take the energy conservation measure warmly, not only may alleviate the electric power intense condition greatly, simultaneously regarding reduces the nonrenewable energy the consumption, the protection ecological environment, maintains the sustainable development, promotes the Hunan economy and so on all to have the vital significance. According to passes the air conditioning profession warmly the research results, the existing airconditioning system energy consumption is astonishing, if uses the energy conservation technology, the existing airconditioning system pletely possibly conserves energy 20%50%.Obviously, if uses the energy conservation measure to the Changsha area airconditioning system and the building system, even if then meets the this summer such burning hot weather, Changsha could not surpass the existing electrical power system peak value power cut.Second, passes the air conditioning domain energy conservation warmly the way and the method science and technology unceasing progress, causes to pass the air conditioning domain new technology to appear unceasingly warmly, we may realize through many kinds of methods pass the airconditioning system warmly the energy conservation.1st, designs carefully passes the airconditioning system warmly, causes it to move in under the highly effective economical condition passes the airconditioning system specially is warmly the central airconditioning system is a huge plex system, the system design fit and unfit quality affect directly the system operational performance. For example the system often all is according to the biggest load design, but actual moves basically is moves under the part load, if the system various part of designs cannot satisfy the part load movement the request, that system energy consumption is very big. Also like the new atmosphere system design, the system should be able to change the new amount of wind along with outdoor meteorological parameter change, by maximum limit reduces the main engine the opening time. May say the airconditioning system the design to the system energy conservation vital role. 2nd, the improvement construction maintenance structure heat preservation performance, reduces the cold heat los we to know speaking of passes the airconditioning system warmly, holds the very great proportion through the maintenance structure air conditioning load, but maintains the structure the heat preservation performance decision maintenance structure synthesis heat transfer coefficient size, . decision through maintenance structure air conditioning load size. Therefore in the national appearing construction energy conservation design standard and the standard, first requests is enhances the maintenance structure the heat preservation heat insulation performance. Third, raises the systems control level, the control room internal heat wet environment parameter, reduces the airconditioning system energy consumption airconditioning system specially is as far as possible the fortable airconditioning system to the human body function is through the air temperature, the humidity, the wind speed, the environment average radiation temperature carries on, the human body to the environment cold hot feeling is these environmental factor bined action result. The former air conditioning control mode is merely observes and controls the air the temperature humidity, even only air temperature. Obviously is not prehensive, will bring many questions inevitably, like airconditioning system to human body function not direct, when environmental variation to the environment regulation not rapid, the human body felt not fortable, the airconditioning system this regulative way will not conserve energy.The hot wet environmental research achievement application use the new control mode method for us to provide the rationale. If uses the fortable appraisal target is the body feeling target takes the airconditioning system the regulative parameter, if uses PMV or the SET* target carries on the regulation to the airconditioning system, not only may solve the tradition control method existence disease, moreover may realize the large scale energy conservation, indicated according to ours preliminary study, uses this control method to be possible to cause the airconditioning system to conserve energy about 30% under the human body fortable condition. The forth, uses the new energy conservation fortable health the air conditioning way as stated above, affects the human volumetric heat fortable environment parameter to be multitudinous, the different environment parameter bination may obtain the same hot fortable effect, but the different heat wet environment parameter bination airconditioning system energy consumption is not same. For example in winter, if we use traditional the air conditioning way, the entire room in air heating, through the air realization human body and the environment heat wet exchange, needs the high air temperature, this time quite is all big through the maintenance structure heat los and the heating new atmosphere heat los.If we according to the hot wet environment the research results, the change tradition air conditioning way, the increase radiating heat (for example low temperature floor radiation heating), this time needs the air temperature drop remarkable drop, may amount to 12~14 degrees generally, but the traditional way generally in 18~20 degrees, obviously the latter has the remarkable energy conservation effect pared to the former. Also has the similar result in the summer. The fifth, the promoted application will use the renewable energy or the lowgrade energy airconditioning system along with the air
