Net Energy Analysis Model for the Evaluation of a Solar Heating,Ventilation and Air Conditioning System.

摘要

This research develops a feasible net energy analysis model from current net energy theory. The net energy model's purpose is to be utilized as an evaluation tool. Net energy analysis is based on the net energy model. Net energy analysis concerns itself with evaluating any system by its performance and interrelationship with the total environment in which the system operates. The model developed specifically addresses a heating, ventilation and air conditioning (HVAC) system. The net energy model was applied to two types of HVAC systems: one powered with conventional fuel sources and one powered with solar energy utilizing a conventional fuel back-up system. The model provided a realistic representation of both HVAC systems. An analysis was conducted on the two systems using data for a base exchange facility at Randolph AFB. The analysis included the use of three net energy analysis measures: net energy, yield ratio, and investment ratio. The results from the net energy analysis were compared to an economic analysis previously conducted to identify differences between the two evaluation methods. (Author)
