| Summary: | 碩士 === 國立臺北科技大學 === 冷凍與低溫科技研究所 === 101 === Today''s Vehicle air conditioning and refrigeration refrigeration technology to use multi-compression refrigeration cycle with the use of R404, R134a refrigerant-based, which require operation of the compressor fuel or electricity consumption, and the use of CFCS ozone depleting refrigerants are in danger. Based on environmental protection and energy saving and carbon reduction considerations, if the exhaust heat recovery vehicle engine cooling system as a vehicle driving force to replace the ammonia absorption chillers refrigerant compressor refrigeration technology will help solve the problem of waste reduction and energy-saving vehicles .
This study developed a way to implement its own exhaust waste heat energy powered vehicles with air conditioning refrigeration system prototype machine and experimentally investigate the operational characteristics associated with cooling capacity, followed by changing the design of the main control parameters, such as different engine speed, pump speed, (simulated) road conditions on the ammonia absorption chiller performance. In addition, explore means of this system for engine emissions and the impact of ingredients, to the future development of high-performance cars of different vehicle air conditioning refrigeration systems applied reference.
The results show that the system developed in this paper recyclable Luxgen SUV7 44% of the engine exhaust waste heat and cooling energy can be directly converted to once, so that the volume 35 × 25 × 45cm3 of space used by cooling to room temperature 7 ℃, put the vehicle when the freezer for rear seat passengers. Study and found to be thus reducing vehicle emissions 14% CO, 22% of HC and 10% reduction of CO2, can prove effective recovery of waste heat into cooling, and can reduce vehicle greenhouse gas emissions.
