| Summary: | 碩士 === 國立勤益科技大學 === 冷凍空調系 === 100 === For promoting the performance of the solar energy air conditioner, its system design point is at the situation of a 2 RT (7.0 kW) cooling capacity, generator temperature 95 ℃, evaporator temperature 8 ℃ and condenser temperature 32 ℃. The system uses groundwater 24 ℃ to cool its condenser in order to reduce its condenser temperature from 42 ℃ to 32 ℃. By the way, the system performance can be promoted up to its three times. Thus, its performance COP can reach to 0.35 at least. At the same time, the outdoor machine volume of the system can be reduced to the half size of its original style with air cooling condenser, because of using groundwater cooling.
Currently, the research of the system adopt separation design makes the evaporator and the suction port line is too long, and induce the overall performance degradation. In this regard, this study to modify the original piping and suction in the generator temperature of 100 ° C, evaporation temperature 8 ° C, condensing temperature of 32 ° C experiments reduce evaporator piping pressure drop 67%, and get more than 0.47, the COP 0.35 and 6.0kW cooling capacity. System compared to 48% of the COP improved piping change, to separate jet air-conditioners Business Feasibility move forward.
