Iam a fooooooollllllll.....???
What saturation temperature should i maintain on different types of systems ?
In case of an air conditioner ,
4.4°C is the saturated suction temp.
So we maintaining the suction pressure to get the proper saturation temp.
ie R22 68.5 psig = 4.4°C
R134a 35 psig = 4.4
R 410a 118 = 4.4
What saturation temperature need for walk in freezer ? (-21°C room temp)
What saturation temperature need for walk in chiller ? (3°C room temp )
If you give the saturation temp. I can calculate suction pressure of different refrigerants .

It's not a joke, i am totally confused because first time in refrigeration

I'm sure its not a joke.
I can help you, just translate your *C readings into *F and I'll help you.

What saturation temperature should i maintain on different types of systems ?
In case of an air conditioner ,
40°F is the saturated suction temp.
So we maintaining the suction pressure to get the proper saturation temp.
ie R22 68.5 psig = 40°F
R134a 35 psig = 40°F
R 410a 118 = 40°F
What saturation temperature need for walk in freezer ? (-6°F room temp needed)
What saturation temperature need for walk in chiller ? (36°F room temp needed)
If you give the saturation temp. I can calculate suction pressure of different refrigerants .

The metering device and air flow determine that!Originally Posted by faisalfadak

So on walk in units, you aim for about 10-15*F lower than the box temp.
So if you want the room temp to be 36*F then look at your P/T chart and find what the refrigerant is 10-15*F below that.
Freezers are about the same, maybe 20*F less than the box temp.
Does that make sense or you need more info?
