Study on Influence Factors of Cooling and Heating Load and Evaluation Index of Energy Consumption in Inpatient Buildings

The energy consumption of hospital is increasing year by year, and the energy consumed in HAVC accounts for larger proportion. This paper took the inpatient building in hot summer and warm winter climate zone for research object, established the theory model of cooling and heating load, designed the orthogonal simulation experiments and simulated the building load using DEST. This paper aimed to research the influence of beds number, added beds rate, patient accompany system, visiting institution on the building load. The simulation results indicate when the beds number and added beds rate is larger, the patient accompany system is not strict, the building load is larger. It will be smaller conversely. The important order of the influence factor is as follows: beds number > patient’s accompany system > addition beds rate > visiting institution. Beds number and patient accompany system have a remarkable influence on the building load (P < 0.05); the influence of added beds rate is not remarkable (P > 0.05). This paper proposes using per inpatient bed energy consumption to evaluate energy consumption in inpatient building when patient accompany system of the hospital is the same. It will be more scientific.
