This is a Honeywell Portable Air Conditioner, Model MN10CESWW. Some parts missing, including remote control, but there's a control panel on the front of the unit. Includes exhaust hose and panel for window, but you may need to do a little work to get it fitted for the window you're connecting to. You can find the user manual online.
Works great, we just don't have a need for it anymore. On the heavy side, but it's on wheels.
