Research Abstract |
A simulation method was completed for the air conditioning cycle for automobiles which takes into consideration such elements as heat transfer in tube of an evaporator and a condenser, air side heat transfer, the flow distribution of the refrigerant, and the influence of oil for HFO1234yf being expected as an attractive alternative refrigerant for R134a. Furthermore, the design optimization of a heat exchanger was attempted for the further deepening which provided guideline for better performance. As a typical example for natural refrigerant, ammonia was selected. Fundamental data corresponding to the practical conditions were obtained. These achievements are to be incorporated into the cycle simulation.
