R-452B, R-452A, R-513A, R-514A, R-1233zd, R-1234yf, R-1234ze & others

R-452B One of the least flammable alternatives for R-410A that, when used as a drop-in, deliver about 5% better dfficiency, opportunity for a charge reduction and minimal 2L flammability. GWP is significantly lower then R-410A (675 vs. 1924).
R-513A Non-flammable alternative for R-134a, which has no impact on capacity, non-ODS and 55% lower GWP (573 vs. 1300). While the theoretical efficiency drop is about 2%, if used as a drop-in, the actual impact on chiller efficiency has been about 4-6%, depending on application.
R-514A Non-flammable low pressure alternative for r-123 that offers the highest performance of all next generation options available today with an ultra low GWP of 2 and yet non-ODS.
R-1233zd A single molecule non-flammable alternative for R-123, which is also non-ODS and has an ultra low GWP of 1. Often referred to as "zd", it is more widely used as foam blowing agent and a low-pressure refrigerant as well.
