water condensed equipment - variation in pressure
water condensed equipment - variation in pressure
(OP)
Hi there
Hope everybody is fine.
Please, I would like to ask you an opinion concerning following odd situation I am facing.
I am dealing with an air conditioning equipment water condensed.
This equipment utilizes an electronic expansion valve.
The thermal load at the evaporator is constant, as well as the water flow and inlet temperature of the condenser.
Super-heating is stable, as well as evaporating pressure.
I would not expect variations in the condenser, too.
Nonetheless, I am experimenting more than 2 bar variation in the values of condensing pressure.
What puzzles me is that at these conditions, high side values should stay stable, and not present following variation.
Please, has anybody of you any experience concerning similar cases ?
Should it be the case, would you be so kind and help me concerning which were the causes ?
Thanks in advance

Make and model?
Some numbers maybe also?
Remember - More details = better answers
Also: If you get a response it's polite to respond to it.

there is air in your system , either on waterside or refrigerant side, or flooding of the condenser with too much liquid refrigerant, which reduces condenser surface area.
