| Abstract: | In order to solve the problem of bathing in domestic university students,taking the hot water system of public bathhouse in Shanghai Jiaotong University as an example,the energy saving benefits of two kinds of combined heat source hot water system,namely solar energy+gas boiler and air source heat pump+gas boiler,are studied.With the cost and efficiency of the system as the evaluation index,provide the change curves of water cost and efficiency of the system every month,and analyzes the influence and the amount of water on the two indicators of solar radiation intensity.Comparing the economy and efficiency of two kinds of composite hot water system,we get the conclusion that the economic benefit of"solar energy+gas boiler"is better,while the energy-saving benefit of"air source heat pump+gas boiler"is better. |
