Mitsubishi Mini-Split Ductless Systems

mr slimMr. Slim is a ductless split air conditioning system. If you are familiar with a central system, you have the basic idea of what a split system is, and outdoor condensing unit and an indoor evaporator unit. The basic difference between the two is that with the central system the evaporator unit is typically found in the attic and has ductwork branched off to the different rooms in your house. With Mr. Slim the evaporator is actually in the room being air-conditioned. The indoor unit has a quiet fan that blows across a cold aluminum coil while in the air conditioning mode. The indoor unit is usually a wall mounted type and this unit is connected directly to the outdoor unit by copper tubing and control and power wiring. In the outdoor unit a compressor cycles refrigerant to and from the indoor and outdoor unit and the room air is cooled or heated based on the direction the refrigerant flows between the two.

More detailed explanation: Mr. Slim works like any basic air conditioning system in that the mechanical components employed and the physical process of evaporation occurs. Mr. Slim is a ductless split design that simply means the indoor unit is separated from the outdoor unit and is connected by a gas and a liquid refrigerant line. The outdoor unit is considered the "hot-side" during the air conditioning process. The "cold-side" unit is located indoors. In the heating process the compressor reverses this operation and the heat energy is evaporated in the outdoor unit and the indoor unit collects this heat energy while a fan blows over the indoor coil and distributes the warm air into the room.

What Is Ductless Technology?

Mr. Slim ductless air-conditioners and heat-pumps are the perfect solution for your home, cottage, restaurant, computer room, retail store and more. These systems allow you to cool or heat without ductwork or windows!

The term 'ductless' simply means no ductwork involved. Mr. Slim systems have two basic components:

  • Indoor air handling unit
  • Slim-line outdoor condenser unit  

These units are easily connected by refrigerant lines running through a small 10cm opening in the wall or ceiling. The outdoor unit cycles the refrigerant through the lines to and from the indoor unit, where the air is conditioned and then distributed into the open space.

Depending on the series, indoor units come in a variety of styles and can be installed in compact tight spaces on walls or recessed into or suspended from ceilings. Installation is as simple as mounting the indoor and outdoor units, connecting the refrigerant lines, and making a few electrical connections. © Copyright. All rights reserved.
