The conception of independent exergy evaluation of temperature and humidity control in HVAC systems is proposed with the corresponding evaluation indexes presented. This type of evaluation process is illustrated in an air conditioning system with primary return air from the view of thermodynamics. The results show that exergy efficiency of sensible heat is larger than that of latent heat. The reason lies in the fact that the destructions in reheat process and condensed water are very serious. It is concluded that the surface air cooler is not an energy saving equipment in respect of exergy utilization, and the regeneration of the supply air stream at the state of dew point would improve its exergy efficiency of latent heat. The analysis indicates that this independent exergy evaluation is benefit for the exergy evaluation for HVAC systems, and it provides effective resolutions. 相似文献

This paper points out the problems in air conditioning and the urgent need in energy saving. By observations and analyses, it shows that the idea of making use of natural resources to improve the indoor air may date back to ancient times. This paper also examines the feasibility of taking advantage of dry or wet bulb temperature, solar energy, underground rock etc. to regulate the room temperature. Finally, it concludes that the above mentioned old idea has such characteristics as energy saving, low cost and less pollution. Therefore, it is a good green plan in energy saving air conditioning. 相似文献

Energy consumption of water intake is one of the key factors for energy saving in the application of the open loop surface water heat pump system. An energy efficiency ratio coupling model for open loop surface water source heat pump systems was established on the basis of the energy consumption model for the water intake and the heat pump units. According to energy saving rate and regulation of energy consumption of water intake, dynamic temperature limits of water intake in different water supply temperature of cooling tower and different pump head were proposed so as to find a calculation method of temperature limits of water intake of open loop surface water heat pumps. Moreover, the energy saving rate of surface water source heat pump systems compared with traditional air conditioning systems under various condition was also calculated. 相似文献

The feasibility of adopting a balanced energy mix mode (domestic solar energy, biogas, coal-fired boiler and radiant floor heating) was proposed. Taking a typical rural residence in Zhengzhou City for example, the study through theoretical analysis and calculation showed that such a balanced energy mix is an economic way and efficient in saving energy and reducing air pollution, and elaborated the theoretical feasibility of popularizing such a heat supply mode in rural areas. 相似文献
