Quantitative analysis of influence of building types on operating energy efficiency ratio of high-efficiency refrigeration room systems

In order to analyse the influence of different building types on the operating energy efficiency ratio of the refrigeration room systems, a representative city is selected in each building thermal zone of the country, 120 models of the refrigeration room system under different building types are constructed, and the hourly energy efficiency simulation calculation for the whole year is carried out. The results show that in the five representative cities, the average energy efficiency ratio level differs by 9.83%±2.19% for each level of difference between different levels of large and small systems, showing good classification characteristics, which basically meets the requirements for energy efficiency ratio classification of refrigeration room systems. When other conditions are certain, the average maximum relative difference of the calculation results of the three typical public building types of office, business and hotel is 2.16%±0.92%. The difference in building types has little impact on the energy efficiency ratio level of the refrigeration room, and the calculation results of the office building model are closer to the average level of the three typical types.
