| Summary: | 碩士 === 國立臺北科技大學 === 冷凍空調工程系所 === 93 === Generally speaking, the medical building consumes a great deal of energy, due to the hospital operates in 24 hours of whole one year, to offer the person which live in and work for its inside, the basic demand of various life which need a large amount of energy, includes electricity, natural gas and water. In order to maintain the indoor air quality of hospital, it needs to lead sufficient fresh air from outside, so that it will cause increase of load of air conditioner, in the meantime, to induce increase of energy expense.
This text was regarded as the case of consuming and planning with energy conservation in real energy of one medical center was set up in the city of Taipei, analyse the exhausted energy situations for the system of heating steam and hot water system. And applying the identity of air source heat pump to collection of heat from airside, leading outside air to inside, and at the same time to draw out the thermo mass to supply hot water system of hospital, it was drawn out the thermo mass of outside air becoming the use of pre-cooling.
According to the experimental result of this research, the range of outside air enthalpy value is between 46.2kJ/kg to 70.8kJ/kg, hot water is under 47.8~55.4℃ operation conditions temperature range, average refrigeration COP of heat pump assembly is 2.5, it is 3.9 of hot COP;when the outside air enthalpy value is less than 30 kJ/kg,making hot COP is less than 3 of the heat pump. According to the outside air enthalpy value of statistics in whole year, the hours that the outside enthalpy value which is higher than 30kJ/kg appeared are 8630 hours,account for 98.5% of the total hours of the whole year,shows that the air source heat pump with practical value of energy-conserving planning.
