This paper presented the matching suitability of solar-biomass hybrid air-conditioning and analyzed merits of these kinds of methods.The performances among solar-biomass hybrid air-conditioning,wet curtain cycle and the cooling cold water unit within the life-cycle were analyzed.De ST was used to simulate the load of the ecological restaurant and TRNSYS for air-conditioning effect.Finally,the results show that cooling cold water with gas boiler has the highest costs,and wet curtain cooling fan system has mi...
