15/07/2009 - Adjustable built-in volumetric ratio Vi
For the three top models of its 134-S and SRC-S ranges RefComp can provide on request a special item to swap the built-in volumetric ratio Vi between two values. Whenever the compression ratio changes the efficiency is then optimized and with it the seasonal performances (ESEER or IPLV) too.
There are currently two possible swap solutions:
-
Vi = 3,2 ÷ 2,6 - Version called “HS” for SRC-S series and “SL” for 134-S series
-
Vi = 2,6 ÷ 2,2 - Version called “SW” for SRC-S series and “LW” for 134-S series
Contact RefComp for making the right choice.

4) Capacity control slide
valve
5) High pressure oil chamber
