Using TEV without Sensing Bulb
Hi there,
We are using sporlan TEV type DAE 10, DAE 15 & AAE 20 for our chiller room evaporators. the system was on service for about 2 years.
Recently we notice most of our TEV sensing bulb having severe defect due to the material not comparetable (Brass/cooper). we are waiting for the vendor to comment since last 2 month.
At the moment, we still need our system to be operate to maintain the tempreture for our product by manually adjusted / set the TEV adjusting stem. we manage to control the desire temperature.
The stupid question here, if we can control or set the desire temperature by trotelling the size of the orifice CV , why we still need to use TEV.
