Key word: HVAC。 Buildings。 Economizing energy techniques。 management for saving energy Along with the economical rapid development, the energy and the environment question are day by day incisive. May foresee, this kind of condition in also will be able to appear from now on, and will be able to be day by day serious. First, passes the air conditioning domain energy conservation warmly the importance and the feasibility along with society39。s development. But in the construction energy consumption, uses in passing air conditioning the energy consumption to occupy the construction energy consumption warmly 30%50%, also is rising year by year. Increases unceasingly along with the average per person floor space, passes the airconditioning system warmly the widespread application, will use in passing the airconditioning system the energy consumption further to increase warmly. This will be able to enable the source supply and demand contradictory further intensification inevitably.On the other hand, existing basically passed the energy which the airconditioning system used is warmly the high grade nonrenewable energy, in which electrical energy has accounted for the absolute proportion. To these energy massive uses, causes the earth resource to be day by day deficient, simultaneously also brings the serious environment question, like in our country39。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
