R22a to replace R22
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,
