Hi everyone!
It's an ice cream counter running with R404A, not reaching lower than -13 deg C. Checked everything, the low pressure seems fine (32 psi while starting and 24 psi after running for 1 hour (TEX)). The superheat seems fine since the suction pipe is frozen until the compressor. There is no way to check the high pressure.
We also have a vertical deep-freezer with R404A, everything seems fine but it doesn't reach -20 deg C.
The ambient temperature here is around 28 deg C and sometimes reaches 35 deg C, could that be the problem?
Have you ever heard of R404A machines giving trouble in hot and humid climates?
Thank you!
