【摘要】 针对目前大型中央空调系统中电动蒸汽压缩式热泵空调系统仍占主导地位的现状,以及开发利用新能源节约常规能源的需要,提出4种太阳能驱动的溴化锂吸收式与电动蒸汽压缩式热泵联合制冷与供暖系统。这四种系统分别由热管式真空管集热器、抛物面槽形聚光集热器,单效、双效溴化锂吸收式制冷机, 以及风冷热泵和水源热泵构成。针对上海地区一座中小型写字楼的具体应用,分析比较了这4种系统的节能性和经济性。分析结果表明,采用抛物面槽形聚光集热器+双效溴化锂吸收式制冷机+风冷热泵组成的系统,同时具备较好的节能性与经济性,一次能源利用率可降低约50％。更多还原

【Abstract】 Currently most of the large central air conditioning systems are electric vapor compression heat pump air conditioning system.For purpose of energy saving and new energy exploitation,four types of combined cooling and heating system consisted of solar powered absorption chiller and electric vapor compression heat pumps,are given out in this paper.The four systems include heat pipe evacuated tube collector,parabolic trough concentrating collector,single and double effect LiBr-H2O absorption chiller,air cooling heat pump and water source heat pump respectively .Comparison of abilities for energy saving and economic analysis were conducted for the four systems.It is shown that the system including parabolic trough concentrating collectors plus a double effect LiBr-H2O absorption chiller and a air cooling heat pump, performances well in both of the above two aspects.The primary energy ratio is reduced by about 50 percent.更多还原
