Re: New system tripping on low pressure??
Very relevant, and the fact that overcharging or undercharging effects subcooling, it also effects the performance of the evaporator, which in turn effects the evaporating temperature, and in turn increases or reduces the latent heat removal.
But as DTLarca says:
Very few refrigeration engineers know their stuff. It's like working in a tyre service center and not knowing what camber or caster is just because he only happens to repair punctures.
DTLarca made a very good point there.
But when working conditions change, SHR changes.
Failing to recognise that, makes a epic failure of your job.
SHR is not a constant figure along the operational envelope.
In need of some examples of refrigeration engineers or installers failures?
