1. High EER

3. Large Capacity

2. Easy Installation

4. Quiet Running

A optimization cooling-ci rcui t design makes theunit more efficient. Take MDS100B for example:it's EER is up to 3.3 (standard cooling condition atfull load), which is much higher than the old styling,and the power consumption decreased by 10%.

With a truly modular form factor, the units canbe installed closely side by side. As all the unitsare of the same depth and height, the side-by-side installation can save more space. Take theinstallation of three 10HP units for example. Theinstallation space is 10.68 square meters only.By using the efficient refnet joint, the WPD of thesystem is reduced, which can save more energy.

The maximum cooling capacity of a standard unit isup to 30 HP, which can meet the need of more than600 square meters. With a combination of modules,

the units can be used even more widely.

The outdoor unit has new-type spiral fan blades.The smooth air absorbing structure reduces theturbulent ow and noise signi cantly. The outdoorunit provides innovative quiet sleep mode (cooling).Unique sound insulation compressor design makes

the system much quieter.

Strong

MDS system can bring you more fresh and comfortable life by means of superior cooling & heating perfor -mances, stepless capacity modulation and high accuracy of temperature control.

Better Cooling and Heating PerformanceMDS system adopts advantaged design and passes rigorous test to ensure superior performance. From -15Cto 48C, MDS system can run in a very good condition, which will make you comfortable.

Reaching the Setting Temperature QuicklyBoth the direct heat exchange between the refrigeration system and the air, and the intelligent temperaturecontrol ensure that the indoor temperature can reach the setting temperature quickly. Meanwhile, the lowtemperature fluctuation makes you much more comfortable.

MDS system has a stepless capacity modulation from 10% to 100%. The output capacity can be closelymatched to the actual demanded capacity. Compared with the traditional inverter, MDS system has theadvantages of higher SEER (Seasonal EER), wider capacity modulation and more energy saving.

High EER

MDS units feature leading-edge system design andhigh EER, thus saving more energy compared withtraditional air conditioners. For most time aroundthe year, air conditioners work at a partial load.Seasonal EER is the main index for judging whetherthe unit is more energy-ef cient. MDS digitalvariable multi systems feature high EER at fullcapacity, and even higher EER at partial capacity.Thanks to this, they can save more energy andeffectively reduce the electricity cost.

Digital stepless capacity modulation with a widerrange

Less on/off operations and smaller startup current5% ~ 20% less capacity modulation losscompared with invert systemsWhen the digital compressor is unloaded, thepower of the unit is reduced to 10% of the fullload power.

MDS digital variable multi systems featurehigh seasonal EER. They can achieve betterheating and cooling performance with less powerconsumption. Compared with traditional systems,MDS digital variable multi systems can save up to45% electricity cost.

Excellent Dehumidifying Performance

The indoor relative humidity is very high in summer, which makes a bad environment on staying indoor. MDSsystem has excellent dehumidifying performance, which can reduce the indoor relative humidity, thus you canlive in a very comfortable environment.

MDS system works at a lower sensible heat rate. It has a suction pressure which lower than a inverter system,therefore provides more powerful dehumidification.

SoftMDS system is the perfect combination of advantaged air handling technology, accurate temperature controland reliable intelligent multi-scroll technology, which makes you more comfortable.

Accurate Temperature Control, Quick ResponseThe indoor load depends on several factors, such as ambient temperature and sunshine. In order to makeyou more comfortable, the air conditioning system should be stepless modulated quickly to keep the indoor temperature in a low fluctuation range. MDS system can fulfill the function of stepless capacity modulationand output different capacities instantly. MDS is the future of the air conditioning system.

Dry bulb temperature control can be as accurate as 0.3 oC.The unique dynamic forecast technology of load demanded.The continuous tracking technology of load.Quick response. The output can be changed from 10% to 100% very quickly.Quick action. The electronic expansion valve enables the system to provide more accurate temperaturecontrol and give more punctual response.

Excellent Electromagnetic Compatibility

While modulating capacity, MDS digital variable multi systems only

shift precision parts, and produce no high frequency harmonicwave. Therefore, they will not destroy with high delity soundboxes, computers, telephones etc. They can be widely used inplaces where interference with the power supply must be strictlyprohibited, such as computer rooms, telecom base stations, TVbroadcast reception stations and telecom equipment rooms.

As the frequency signal changes, high frequency systems will

generate high frequency harmonic waves with frequencies 5, 7,11, 13, 17 19 times as high as that of the power supply. Asa result, the power factor of the electricity network is reduced,the capacitor and transformer overheat, ashing points appearat the uoroscopes and oscillographs, and the precisionof precision instruments are lowered.The electromagneticinterference (EMI) of invert systems are now internationallydeemed as an environmental pollution. The electricity costspent on suppressing EMI also makes users sweat.
