I am a piano trainer and need to install air conditioners in 25 piano rooms. Is there a suitable plan?

In this way, you put it in a cupboard. Do you do it every once in a while? If not, install ceiling fans to circulate cold air, or install wall-mounted fans.

You can make PVC pipe, 160 pipe, or you can make an air duct with foam board of central air conditioning pipe.
