Split systems consist of indoor and outdoor unit, equipped with infrared remote control, equipped with a variety of options for cleaning the air, ease of operation, the compressor can be fixed and variable (inverter) power. The indoor unit is designed for installation on the wall, on the ceiling of the room.
This type of air-conditioning was the most popular, because the compressor and condenser cooling fan (the most noisy) are placed in outdoor unit, so evaporator and fan blower located in the interior, and named as indoor unit. Six kind's of indoors are presented by Midea into Light-commercial serie: compact 4-way cassette, 4-way cassette, duct with middle pressure, duct with high pressure, floor-standing and celling-floor (universal). Capacity of units until 3.5kW to 16kW, two main groups of system present - with on-off compressors, and DC-inverter compressors
"Split" means "separated" - indoor and outdoor units are connected to pipes forward and reverse pumping Freon (refrigerant), the pressure created by the compressor and throttle valve, which ensures the Carnot cycle in the specified temperature limits. Upon reaching the desired temperature in the room, the compressor is deactivated. In split-system inverter compressor operates at a variable speed, and this provides another "degree of freedom" for providing a more accurate temperature control.
This scheme was introduced in the 60s of the twentieth century, when the designers set out to reduce the noise level and the size of air conditioners, for wide application in daily life, previously produced only windows and industrial monoblock system, which severely limits their use in homes and offices.
Semi-industrial conditioners
This type of split systems supplied with this indoor unit, which must be mounted on the ceiling, providing a first mounting block, and then install the decorative panel entry and exit of air. The main air distribution occurs in 4 directions, additional angular channels provide a more uniform air flow, the air flow deviation can be adjusted vertically by deflecting louvers. All cassette indoor units are equipped with built-in drain pump, decorative louvre panel and remote control are also included. Wired remote can be installed as an option.

This is a split system with indoor unit that can be mounted on the ceiling or wall, respectively, given the specificity of the layout and placement of objects in the room. Main distribution of air occurs only in 1 direction, additional deflection of the flow in the side rails provide manually adjustable slats, the deviation of air flow can be adjusted vertically by deflecting louvers. All wall, ceiling indoor units are equipped with remote control supplied. Wired remote can be installed as an option.
This is a split system with indoor unit that can be mounted on the ceiling or wall, so sometimes referred to as "console" or "universal". Main distribution of air occurs only in 1 direction, additional deflection of the flow in the side rails provide manually adjustable slats, the deviation of air flow can be adjusted vertically by deflecting louvers. All wall, ceiling indoor units are equipped with remote control supplied.
Cantilever indoor units provide uniform distribution of treated air flow in the room, directing a powerful stream of treated air along the walls on the 4 directions (up and down, left and right), thus avoiding direct contact with cold air to people, pets and plants. Indoor unit cantilever is placed vertically on the wall just above the floor.
Column type (Floor-standing) air-conditioners installed in lobbies, restaurants, cash halls, shops and conference rooms, a large area. They are simple to install, create a powerful air flow directed by two rows of louvers, installed on the floor of the premises and appearance similar to the cabinet. They are used in areas where it is impossible to use the surface of walls and ceilings, and ceiling height up to 5 m, while on the floor there is a stock area. Lineup of floor-standing units –it’s a 4 models, from 7 to 16 kW, each unit is controlled only individual control.

Indoor unit channel type allows concealed installation in suspended ceilings and air distribution channels, air ducts. These systems are often used in areas where design is important, since the block itself is not visible in the room, but only the lattice diffusers or air distribution visible to the eye. Blocks channel-type medium pressure can be connected to ducts (channels) with a length of 3.7 m. As a rule, such a solution is sufficient for a single storey cottage or a large store room with separated rooms, a small distance between them.

These systems are often used in areas where design is important, since the block itself is not visible in the room, but only the lattice diffusers or air distribution visible to the eye. Blocks channel-type high pressure can be connected to ducts (channels) with a length of 8-14 m. As a rule, such a solution is sufficient for small-sized cottage or a large store room with separated rooms, where it is important to submit the air over long distances.

Outdoor units with constant power compressor provides high efficiency and reliability, supplied semi-split systems or can be supplied separately as KKB central vent installations. Electronic protection systems installed by the manufacturer and monitored during a number of important parameters. Manage the outdoor unit can both internal supplied Midea, or automation system by the criterion of start of the compressor, fan, 4-way valve, in the case of their role in the CMC.
Universal outdoor units are supplied as part of semi-split systems of various types.
Midea air conditioners have various forms of control. By default, the control is carried out by an infrared remote control unit, which comes with air conditioning. However, various wired control panels can be connected to the indoor unit, either as usual or with a weekly timer, for example. It is also possible to control several air conditioners from one group controller.
