In especially hot summer, we all appreciate the vital tension electricity. It is foreseeable that this situation will arise in the future and will bee increasingly serious. Energyefficient bee more imopent.Keyword: HVAC systems。s energy consumption is significant. Another example is the design of the new air system, the system should be able to change with changes in outdoor fresh air meteorological parameters in order to shorten the maximum time the host of the opening. Can be said that the system airconditioning system design plays an important role in energy conservation. improve the insulating performance of building maintenance to reduce the loss of hot and cold We know that the HVAC systems, air conditioning load by maintaining the structure of a large proportion, while maintaining the insulating performance of the decision to maintain the size structure of plex heat transfer coefficient, which determine the structure of the air conditioning load by maintaining the size. Therefore, state policies and standards for building energy efficiency design, the first requirement is to increase the thermal insulation properties to maintain the structure. improve the system control level, adjust the indoor thermal environment parameters, to minimize energy consumption of airconditioning system Comfort air conditioning system, particularly the role of airconditioning system on the human body through the air temperature, humidity, wind speed, the average radiation temperature of the environment, and human feeling hot and cold on the environment of these environmental factors bined result. Before airconditioning control method is only monitoring the temperature of the air humidity, air temperature, even only. Is obviously not prehensive, is bound to bring many problems, such as the role of airconditioning system on the human body does not directly, when the environment changes, the regulation on the environment is not rapid, the body does not feel fortable, airconditioning systems that control methods are not saving. Thermal environment of the application of research results, as we approach a new control method provides a theoretical basis. If that is a fort evaluation index of somatosensory indicators as airconditioning system control parameters, such as the use of PMV or SET * index of the air conditioning system to control, not only can solve the shortings of traditional control methods exist, and can achieve significant energy conservation, according to our Preliminary research shows that using this control method can make the air conditioning system in the human fort conditions save 30%. The use of new energysaving air conditioning fortable and healthy As noted above, affect human thermal fort environment of many parameters, different environmental parameters can be the same thermal fort effect, but different thermal environment parameters for energy consumption air conditioning system is not the same. For example, in the winter, if we use a traditional air conditioning, heating the entire indoor air through the air to achieve the body heat and moisture exchange with the environment, we need a higher air temperature, then heat loss by maintaining the structure and heating fresh air greater than heat loss. If we follow the thermal environment of research results, changing the way traditional airconditioning, increased radiant heat (such as low temperature radiant floor heating), then the need to lower the air temperature dropped significantly, and can be reached from 12 to 14 degrees, while the traditional general 18 to 20 degrees, obviously the latter than the former has significant energy savings. In the summer, a similar result. promote the use of renewable energy or lowgrade energy, airconditioning systems With the ext
