Comparison and Analysis of Building Heating Schemes of Expressway Service Areas
Taking a heating reconstruction project of the solid heat storage and air source heat pump in an expressway service area in Shanxi Province,this paper theoretically studied the influences of the environmental temperature and peak-flat-valley electricity prices on two schemes'applicability and economy.The comprehensive analysis indicated that under specific working conditions,the air source heat pump should be used to supply the heat when the environmental temperature is higher than a certain critical temperature.The greater the peak-falt-valley electricity price difference,the more obvious the advantages of the air source heat pump.The results can provide a theoretical and practical basis for selecting heating schemes for the expressway toll stations and service areas in Shanxi Province.
