What you describe is a packaging unit (evaporator and condenser in the same box) that is placed outside and then channeled into a habitation.Les packaging units are commercially all the time in the United States uses. But the “plumbing” is made of metal working, that you often see on the roofs of the shops. Sometimes the units behind the shops. But to eliminate environmental laws and fire off more flexible working hours management. Within the flexible insulated wires are often used following the lines of the hull. The only application I’ve seen for such a system is that supply services, temporary air conditioning and can provide such a unit placed on a truck in a room with soft lines mounted ductless split fenêtre.Unités have also been used for many years on the world, but in the U.S. market only recently.
