Black Decker portable air conditioner. Basically this model without the remote control: https://www.amazon.com/BLACK-DECKER-Portable-Conditioner-Display/dp/B01DLPUWHQ?source=ps-sl-shoppingads-lpcontext&ref_=fplfs&smid=ATVPDKIKX0DER&th=1

In good condition and works well--definitely has saved me many summers living on campus with no air conditioning.

Pickup near campus.
