MDS II is a new product built on MDS I. With a better design and new technologies, it fits into a wider range of applications, marking a revolutionary step in the history of air conditioning development. 1. Higher EER A new cooling circuit design makes the unit more efficient, increasing its ERR from 3.0 to 3.3 (standard cooling condition at full load), and lowering the power consumption by 10%. MDS100B system 3.3 100% EER 2.8 Digital operating 2.
3. Larger Capacity The maximum cooling capacity of a standard unit rises from 10 HP to 30 HP. The coverage of a single unit increases from 200m2 to 600m2. With a combination of modules, the units can be used even more widely. 600m2 MDS 10HP 200m2 MDS 30HP 4. Quieter Running The outdoor unit has new-type spiral fan blades. The smooth air absorbing structure reduces the turbulent flow and noise signiflcantly. The outdoor unit provides innovative quiet sleep mode (cooling).
Strong MDS II system can bring you more fresh and comfortable life by means of superior cooling & heating performances, stepless capacity modulation and high accuracy of temperature control. Superior Cooling and Heating Performance MDS system adopts advantaged design and passes rigorous test to ensure superior performance. From -15°C to 48°C, MDS system can run in a very good condition, which will make you comfortable.
Save Energy MDS system is designed with the most advantaged digital variable compressors, which is much energy saving. It can save you a lot of money. High SEER (Seasonal EER) With a state-of-the-art cooling circuit design, MDS II provides a higher EER but consumes less energy than a traditional air conditioning system.In most time of a year, the air conditioning system is running in part load condition, which wastes a lot ofenergy. Whether the units are energy saving or not is depended on the SEER.
Soft MDS system is the perfect combination of advantaged air handling technology, accurate temperature control and reliable intelligent multi-scroll technology, which will make you more comfortable. Accurate Temperature Control, Quick Response The indoor load depends on several factors, such as ambient temperature and sunshine. In order to keep you more comfortable, the air conditioning system should be stepless modulated quickly to keep the indoor temperature in a low fluctuation range.
Advantaged Variable Technology MDS system adopts the “stepless capacity modulation”technology to make sure that one outdoor unit canconnect up to 48 indoor units. Compared with the traditional split conditioner, MDS system reduces the quantity of outdoor units, which makes the building more elegant. Various Types for Option The indoor units can be selected based on the customer’s requirement, which makes the house more splendid.
Soft Excellent Electromagnetic Compatibility For MDS system, the Digital Scroll motor runs at a constant speed throughout the operating range, unlike the variable speed compressor technology. Due to this design, there is negligible electromagnetic interference. This unique feature eliminates the need for expensive electromagnetic suppression electronics required to ensure electromagnetic compatibility. MDS system EMC standard Inverter system Ijhi.
Sanitary MDS system adopts advantaged technology to prevent any penetration of fungi or bacteria into the system, to improve the indoor air quality, which can give you a healthy and comfortable living environment. Fresh Air Introduction Every unit has the function of introducing the fresh air into the indoor to improve the indoor air quality. HRB fresh air heat recovery unit is optional for fresh air introduction and energy saving.
Silence MDS system adopts the advanced compressors to reduce the noise level. The outdoor unit has new-type spiral fan blades. The smooth air absorbing structure reduces the turbulent flow and noise significantly. A unique sound insulation compressor design makes the system much quieter.
Simple The MDS system are simple and reliable, the design and installation are more flexible. Unique Installation Maximum piping length: 150m, Maximum height 15m between the indoor unit and the outdoor unit: 50m The outdoor unit of MDS system is designed as package, the compact structure occupies less space and is easy to move. The outlines and dimensions of the innovated units are compact.They can be installed side by side to save space.
Simple Simple Maintenance Even if the MDS system has some malfunctions, the maintenance is very easy. Because the control devices are simple and only a few devices need maintenance. When there are some malfunctions in one zone, they do not affect the operation in other zones. Malfunction Auto-diagnosis and Alarm MDS system provides the unique function of malfunction auto-diagnosis and alarm, which can make sure that the units can run more reliably.
Simple Central Control MDS system can be connected up to 48 indoor units. 32 outdoor units can be controlled in a network through a centralized controller. The monitor software can monitor 1536 (32x48) indoor units in real time at the same time. The communication cables between indoor units and outdoor units are very easy to arrange. MDS system has a strong function of displaying the malfunction, which can save maintenance time and cost.
McQuay Software Management System Real-time Monitor System monitor software: Powerful MDS real-time monitor software can implement indoor control, system control, circuit control and service control. It helps users or serving personnel to view detailed parameters and unit data. Description of main control functions: Indoor Monitoring Set the mode, fan speed, auxiliary setting, and temperature of indoor units. Switch on/off indoor units.
User-specific Biller With a precise flow control technology, the user-specific biller built on the real-time monitor enables you to measure the quantity of electric charge more reasonably. The biller also allows you to group up to 1536 indoor units as you desire, to calculate the electricity charge accurately in real time. It brings you great fiexibility, making it easier for you to change the grouped devices and collect statistics.
