Type of article: Article

Summary

States there is a need to develop a suitable charged thermostatic expansion valve to work with systems charged with R134a. Maintains that the conventional R12 cross-charged valve does work, but with a slight loss of superheat sensitivity. A pure R134a-charged valve lacks a constant superheat over a range of evaporator temperatures and may require a smaller orifice size than the conventional cross-charged valve.
