PTAC in nursing home patient rooms

Hi Folks;

We have 34 of the model No.: EZ09H2CSC151AAY (Islandaire) in our Nursing Home. We were going to install split system A/C units and rip out the PTAC's, but we need 2 air changes per hour, and may have to continue to use a PTAC. I guess we could run duct work and install a rooftop unit, but that is cost prohibitive.

Anyone have any other ideas on satisfying the outside air requirement, other than replacing the PTAC's with PTAC's?

Are you saying you want to install regular central split AC ? Central split AC is different from PTAC, it involves duct work, location of air handler and condensing units and the size of the unit, etc.. you need to call an AC expert to do some design work first (includes load test). 2 hour air change is not a problem, but the condensing unit must be outside (either on the roof or on the ground). air change device is also need an outside duct. Give us more details on what you really want, may be we can help.

No, the Nursing home wanted to install Mini-splits in the rooms, like this: LG air conditioner, LG heat pump, lg mini spit, lg Air Conditioner, lg ductless online wholesale direct from GoDuctless

Bu2 we need 2 air chtnges per hour, so they will not work. We are trying to avoid installing duct work so it looks like replacing the existing PTAC with an efficient model, is the way to go.

Through the use of a ceiling cassette type evaporator you can duct in fresh air. This is the ONLY way you can get ventilation with a mini split.
