condensing pressures
Hi
I've been thinking (dangerous i know) how you guys relate your servicing to optimising power consuption, particularly concerning reducing head pressures/temps , now the magic 40* has served me well, systems that are sized correctly with correct super and sub heat are genarally happy, but reading articles that state that the condensing pressure should be pressure diff required across tev + evap pressure + system losses (1.5 bar ish?) to achive lowest optimum head pressure has got me pondering.
Firstly i'm struggling to find the diff info required, secondly i suspect that the figures arrived at are lower than rules of thumb suggest.
How do you reconcile this? especially concerning the evil r407c which loves to flush.
Ill be interested in your answers
