Analysis Of Energy Consumption And Discussion On Cold And Heat Sources Of HVAC System In Hospital Buildings

The hospital is a medical institution with the primary purpose to provide medical care services,there are some special requirements for each room with different functions in the building.The air conditioner design is much more important than that in the resident building. We pursue the indoor air quality, meanwhile, we should pay attention that the proportion of energy consumption of HVAC is growing dramatically. So how to guarantee the air quality in the hospital and the prevention of cross-infection, while improving the energy conservation in design is a tough task to the designer.This paper analyzes the energy consumption and humiture of the air conditioning system in a hospital by census, statistics, test and calculation.The analysis databases indicate that the air conditioning consume most energy of the whole hospital, and meanwhile, the energy which cold and heat source system consumes takes up half of the total system. This shows that select good cold and heat source system is very important.In addition,the paper made some solutions to save the electricity and energy according to the research data and these solutions can be used to the design of the new surgical building in hospital.In the design of air conditioning in the surgical building in hospital,Analyze and contrast the different projects about cold./heat source and finally choose soil-source heat pump and wind cooled/heated pump system as the cooling/heating source of the building. Analyze the whole design of air conditioning system in the new surgical building,focus on the soil-source heat pump and wind cooled/heated pump system and introduce its working principle as well as its advantages in this project.Utilizing the soil-source heating pump, analyze the layout of underground heat changer and adjust underground burying tube system.According to the analysis above, having an overview on the energy-conserving design of the new surgery building in hospital, pointing out the shortage of previous design and adjusting the project accordingly are very meaningful to future design of surgery building.
