New High Performance, Low GWP Refrigerants for Stationary AC and Refrigeration
نویسنده
چکیده
In response to concerns about global climate change, and in consideration of probable legislation that may impact the production and use of refrigerants with high global warming potential, a set of new refrigerant candidates has been developed for evaluation. Some candidates are designed for stationary air conditioning in residential and light commercial end uses. Other refrigerant candidates were designed more specifically for use in medium temperature refrigeration applications. These candidates all have GWP values that are reduced significantly from R-134a, R-410A and R-404A values, and have good predicted performance characteristics as determined by cycle modeling. Model results must always be validated by actual system tests, and that work has been underway for some time now. System tests are indeed showing that the predicted model results are achievable. This presentation will describe these candidates and show some results from evaluations of their cooling and heating performance properties and LCCP (Life Cycle Climate Performance) comparisons.

In this work, a novel dual-nozzle ejector enhanced triple-evaporator refrigeration cycle (DETRC) without separator is proposed to improve the performance of the conventional ejector one (CETRC). The performance of DETRC is analyzed and compared with CETRC in term of energy coefficient of performance (COPen). Under given operating conditions, the COPen improvement of the no...

The working fluids most widely used for small and mid-sized air conditioning systems globally are R-410A and R22. While these fluids have many positive attributes for cooling and heating, they are the subject of valid criticisms regarding their high direct global warming potential (GWP) and, in the case of R-22, ozone depletion potential (ODP) also. In the interest of improved environmental sus...

Recently, R32 refrigerant, which has low global warming potential (GWP), attracts much attention as an alternative one instead of R410A and has started to be used in practical systems of room air conditioners (RAC), but compared with natural refrigerants, its GWP of 675 is still high and it is required to use refrigerants with much lower GWP. In addition, although R134a (GWP=1300) is widely use...
