Simple Explanation: Back
Mr. 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.
Air Conditioning Basics:
The process of air conditioning is dictated by simple physics. Through the evaporation process heat is absorbed by the aluminum fan coil in the indoor evaporator unit and is removed from the room by the gaseous refrigerant. The heated refrigerant (pressured by the compressor) flows into the outdoor unit’s aluminum coils. Here a large fan blows across this coil to discharge the heat energy. The liquid refrigerant is cooled by this process and is cycled back to the indoor unit where a fan blows across it and distributes cooled air into the room.
Most air conditioning systems have four mechanical components:
-
- a compressor
-
- an expansion valve or metering device
-
- an evaporator coil and blower
-
- a chemical refrigerant
