Abstract:
With the increase of mean all season temperature in many cities and demand of hot water for domestic used, high energy consumption of cooling system and electricity are rising continually and rapidly. Thus, the conservation of energy in domestic application more and more important to minimize resources consuming. Following that, room thermal stratification, amount of heat rejected by condenser and recovered by heat recovery is an effective means of saving energy. In this paper, a model of domestic air conditioning system equipped by heat recovery unit was conducted to get the thermodynamics performance, cooling capacity, work of compressor, amount of heat recovered are taken as a case study to evaluate the energy saving and conservation effect. The result from time series data indicate installed the heat recovery unit in domestic air conditioning give benefit to thermodynamics aspect of refrigeration system about 46.1-53.8 percent so it has great potential for energy conservation. Then system that made use of waste heat to produce hot water to serve the building needed was proposed and the heat recovery also has economic viability. Therefore, using the heat recovery system in domestic air conditioning can improve the energy efficiency and realize the energy saving.
