Inverters in server room
I have recently gained a new customer with an issue that their server room sometimes maintains a room temp of around 24c (set point 21c) and just recently the room temp reached 29c. I believe from reading various other posts on the forums, that I might have an issue with the humidity/wet bulb temps, here is the information I've taken from the server room and air conditioning units. I'm thinking of adding humidifiers.....but thought I put it out there first for a more experienced point of view.
Server heat load and room - around 11.5kw.
We have two Mitsubishi power inverters, Indoor m/n: PKA-RP4FAL Outdoor m/n: PUHZ-RP4FAL
Ambient temp = 5c
Suction pressure = 100psi then would raise 105psi
Suction actual temp = 1c to 8c
Indoor return air temp = 26c
Wet bulb temp = 12c
R/H = 25%
If there is any recommendations out there it would be much apprieciated. Mitsubishi tech said to add more units.
