What is a Mr. Slim? How Does It work?

Mr. Slim is a split-ductless air-conditioning system. If you are familiar with a central system, you have the basic idea of what a split system is: an 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 units, and the room air is cooled or heated based on the direction the refrigerant flows between the two.

Detailed Explanation:

Mr. Slim employs the same mechanical components as any basic air-conditioning system whose interactions cause the process of evaporation to occur. Mr. Slim is a split-ductless design, which 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. Then the indoor unit collects this heat energy while a fan blows air 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 the cool air into the room.

Mr. Slim Filters & Cleans Your Air:

Mr. Slim is designed to circulate air within the space using about the same power as a 40-watt light bulb. Plus there are two standard built-in filters that clean the air and trap virus and toxins while also deodorizing.

Anti-allergy enzyme filter which uses artificial blue enzyme catalyst on the filter filaments to capture harmful microbes
Hybrid Catechin Pre-filter fibers infused with a bioflavinoid found in green tea that has antiviral and antioxidant properties

Mr. Slim Takes Care of Humidity:

Mr. Slim’s normal operation takes care of moisture very nicely. The indoor unit’s coil draws the moisture out of the air and wrings it out in the form of condensation that is drained outside or to a near-by drain. Mr. Slim is rated to remove between two to five pints per hour when the return air temperature is at 80 deg.F dry bulb or 67 deg.F, and the indoor relative humidity is around 50%. The outdoor conditions become wetter and can affect the indoor conditions. This will cause Mr. Slim to remove moisture out of the air at a faster rate.

Mr. Slim even has a mode of operation called DRY mode. This dehumidification feature provides added moisture control without lowering the temperature of the room. In this mode the fan speed slows slightly so that the air can spend more time on the indoor coil therefore wringing out more moisture.
