Hi,

I used Precision Air of Liebert CM+ with R-22 compressor. But my customer has changed refrigerant to R22a and the cooling capacity drop!

Normally, I charged R-22 5 kg into the pipe at 65/250 psi. After changing, I measured 40/250 psi at 4 kg.

Temperature was rising from 22C to 24C.

I don't know why. Please help!

Thanks,
