摘要
在与传统能源系统方案比较基础上,提出冷热电联供(BCHP)系统经济性的增量评价法,从而避免了热价、冷价等人为因素干扰,使BCHP系统经济性的评价更加客观,并针对大学的BCHP系统进行经济性案例分析。分析认为,最大利用小时数、运行效率、能源价格乃至系统容量等因素对冷热电联供系统经济性影响很大,进而认为体育场馆、会馆等设备利用小时数少,住宅电价低,这类用户不宜采用BCHP系统。合适的容量利于提高BCHP系统的经济性。
On the basis of a comparison with the traditional energy source system versions,proposed was an incremental method for evaluating the cost-effectiveness of a BCHP(building cooling,heating and power) system.As a result,man-made interference factors,such as the heat and cooling energy prices etc.can be avoided,making the evaluation of the cost-effectiveness of the BCHP system more objective.In addition,the authors have also conducted a case analysis of the cost-effectiveness of the BCHP system employed on campuses.The results of the analysis indicate that a host of factors,such as the maximum utilization hours,operation efficiency,energy price and system capacity etc.,exercise a major influence on the cost-effectiveness of a 'cooling,heating power supply' cogeneration system.One is further led to believe that because such facilities,as stadiums and assembly halls etc.are characterized by few utilization hours and residential housings feature a low kilowatt-hour price,it is inappropriate for users of this category to employ the BCHP system.A proper capacity is favorable for enhancing the cost-effectiveness of the BCHP system.
