General

With years of design and manufacturing experience, Midea carried out the new 2nd generation

Air Handling Unit (MKSII Series) with a series of improvements and innovations to meet market

demand. As comfort air-conditioning, it can be widely used in hotels, theaters, shopping malls,

office buildings, schools and other places; as for industrial use air conditioning, it can also meet

the electronics, chemical, medical, pharmaceutical, cigarettes, food, light industry and other

industries needs.

The standard MKSII Series AHU can be divided into 3 types which are suspended, horizontal

and vertical types. The air volume is from 2000 m3/h to 40,000 m3/h (1170 to 23,500CFM).

3

Features Cold-bridge Free(Thermal break) Design

Both the framework and panels are designed to be isolated. And the cavity of the framework and panels

are filled with high-density polyurethane foam (density ≥ 50kg/m3) to cut off cold bridge completely,

which can effectively prevent cooling capacity loss and external condensate.

Multiple-seal to Prevent Air Leakage

Units using multiple “ladder-style” structure, both inside and outside ladder are with closed measures.

Coupled with the negative pressure design, can ensure that the units of air leakage rate is a low air leakage

rate ≤ 0.29%, only the provisions of the national standard 1 / 10, more no danger of water leakage.

Lower Noise Running

Famous-brand fan is in use. The professional selection software makes sure the optimum working point

and outlet velocity to guarantee the smooth & low noise air flow in the duct.

4

More compact size, Space saving

The dimensions of the units are optimized and the performance is maintained. The units with more

compact size save the installation space rapidly.

Optimized water pass, Higher heat transferring efficiency

The coil uses windowed high-quality aluminum fin staggered arrangement, coupled with a wide range of

flow path design optimization, which is taking into account the higher heat transferring efficiency and

lower liquid side resistance.

Better appearance, Anti-corrosion and anti-damage

Fillet corner, beautiful color steel with protection film that can against rust, corrosion and damage while

transportation.

5

Assembled structure, Easier maintenance

Assembled structure is easy for assembly and maintenance at site , also it’s suitable for CKD

transportation.

Pipe Connection Direction

Face the air inlet (along the air flow direction),

If the connection pipes and maintenance access is left side, then the unit is left-connection unit,

Otherwise is the right-connection unit.

Capacity Correction at Non-standard Conditions

Calculation Formula:

Q = F1×F2×F3×Q0

Legend: Q0 --- Cooling capacity at standard conditions, refer to the specifications

F1--- Temperature correction factor of cooling coil

F2--- Water ΔT correction factor, refer to Fig.1

F3--- Water flow velocity correction factor, refer to Fig.2. According to the average flow

velocity of Midea coils, we take F3≈1.02
