ShareBlocked fan test.
Author(s) : TOMELL P.
Summary
An internal pressure relief valve (IPRV) is used to limit the maximum system pressures by venting the discharge gas into the suction side of the compressor. The IPRV works with the overload protector to keep the system from unsafe operation. Air conditioning units with an IPRV were blocked fan tested. Systems that operate in high ambient conditions can open the IPRV and cause nuisance shutdowns. Recently designed systems with minimized coil size has required the reexamination of IPRV selection. A brief review of the conflicting requirements and resolution is proposed.
