Author(s) : OHKUBO S., ARIMOTO H., KOMATSU Y.
Summary
In order to suit for global HFCs regulations,R404A, which is one of the most widely used for commercial refrigeration globally, is going to require to be replaced in most of refrigeration applications due to its very high global warming potential (GWP). In this paper, some of refrigerants developed as alternative for R404A are introduced and make comparison withR404A in calculated and experimental way. According to the both comparison, COP of R407H is higher than that of R404A, especially in middle temperature. In addition, R407H shows high stability even in the strict condition compare to HFOs. Therefore, R407H can be one good alternative for R404A in terms of following four viewpoints; safety, environmental impact, energy efficiency and cost-effectiveness.
