Operating analysis of multi-energy complementary air conditioning system of a hotel

Combined with the actual cooling and heating load and hot water demand of the application site, the compound evaporative condensation air-source heat pump units, low temperature strong hot air-source heat pump units and heat recover air-source heat pump units are adopted for the accurate adaptation design for refrigeration, heating and hot water. Taking a four-star hotel in Zhengzhou as an example, this paper presents the principle, calculation model, energy saving rate and operation cost of these three kinds of air conditioning units. Compared with conventional air-source heat pumps and gas boilers, the energy saving rate of this case can rise by 24.5%. The accuracy of the calculation model is verified by using the actual operation data of the units.
