how to use a refrigerant comparator

[ActiveEngineer]

Is there know such guide?

looking find out how you work out what the suction pressure/tempature

For the likes of a HVAC system running on r59 what suction tempaturte would be and how you work it out


Hope i have come over bit better this time cheers for any help you guys can give me

Have you ever done any training?

I ask because the information you are asking for does not exist (not in the form you want) but you would know that if you had any training.

Why don't you introduce yourself and explain what you want. We can work from that point and perhaps give you some assistance.

Hello Taz,

I am a mechical tech and i work offshore in the north sea and have know refrigeration training at all.

Like my other questions i would like to know how you guys work out the suction pressure/temperature of systems.

suction pressure/temperature of a HVAC system running on R59 would be ?

You need to know design TD (difference between evaporation temperature and air/water/brine entering temperature) for your heat exchanger.
Subtract evaporator design TD from evaporator actual air/water/brine entering temp to obtain required evaporation temperature, and add condenser design TD to actual entering air/water/brine temperature to that condenser to obtain condensation temperatures.
Then convert that temperatures to saturation temperatures of refrigerant in system and you have your expected pressures. Now compare that with your measured pressures (or temperatures, if gauge has scale in temp. for that refrigerant) to establish is your system pressures are OK.

This helps alot mate thank you very much.
