| Summary: | 碩士 === 國立臺北科技大學 === 能源與冷凍空調工程系碩士班 === 97 === In this study, utilizing the waste heat from heat pump chiller of the HVAC system and water level issues of heat storage tank of the heat pump system are discussed. Assuming these conditions are known as follows: the capacity and temperature of heat storage tank, load demand and etc. It is trying to evaluate the capacities of heat storage tank operated in accordance with the demands, utilizing the water level control mode and time program control mode and based on the different capacities of heat pump system. In addition to heat the make-up water of heat storage tank to the initial conditions during the off-peak power period. The study will find out how much energy cost can be saved by using these two control mode, and to improve the economic benefits while lowering the total life cycle cost.
In this case, set the total life cycle cost as objective function, the make-up water level as variable, with known thermal storage tank, heating system components, and heat pumps of different sizes. Then through an analysis of program system to seek out the best operating conditions of the system so as to reduce energy consumption and raise economic efficiency of the heat pump system to achieve the purpose of energy conservation to reduce carbon.
