Suction Pressure R7-17

[NH3-Iceman]

I work in production facility that runs 20.3 suction to maintain 45 degree room temps on one vessel another that maintain 26 degree room temps and and 34 degree room temps on another. My question is other operators and managers say we will not maintain room temps if we was to raise our house suction pressure to my knowledge 20.3 Psi is very low pressure to maintain those temps how do I go about proving that we can raise our house suction and still maintain the temps

NH-Iceman,
In general you run suction pressure 10 deg C below lowest room temperature.
