Data center adopt traditional closed-cycle air conditioning, it has maximum flexibility. As a result of the elevated floor, so all the areas of room can supply air evenly in the vertical direction. Exhaust hot air supply to the air conditioning units through the shortest passage. Increasing heat load require a well-designed air distribution and full high elevated floor. Redundant system can ensure maximum availability and energy-efficient free cooling. Midea as an expert cooperation partner for you, is responsible for the installation and startup of equipments. And make maximum use of equipments during the life period.

Modern information and communication technology are tending to compact, fast and efficient. Intensive server racks can produce more than 30kW cumulative heat load. But in this situation traditional air circulation system is inefficient. In this case, adopting traditional closed-cycle air conditioning with liquid cooling technol-ogy for server racks can make an efficient solution. In this way, users benefit from the closed-cycle air condi-tioning which components have less thermal stresses flexibility, while high heat load in the dense area of racks is transferred to the liquid cooling system, and can be removed reliably.

Telecommunication system using containers, machine rooms and base stations face special challenges on air conditioning technology. Midea provide a wide range of various solutions required customization on inter-nal and external of communication facilities. Whether your main objective is to get the best protection against accidental damage, or to make full use of the equipment room space. Midea can both provide the ideal air conditioning solution.

Our precision air conditioner units can create reliable and accurate air conditions according to your demands. Meanwhile, top technology such as free cooling technology can help you to achieve the operation cost savings. Midea is expert as your cooperation partner on installation, commissioning and maintenance, and provide comprehensive solution for you.

Relying on abundant strength on air conditioner design and manufacture and good quality on service and support platform, after 7 years of rapid development, Midea base station air conditioner has been widely applied in communication base stations, 3G base stations, microwave satellite ground stations, small outdoor rooms, laboratories, testing rooms and storage rooms.

To meet the requirements of communication industry, achieve energy saving and operation costs reduction, Midea specially launch out split down outlet base station air conditioner. According to the features of heat radiating for base station, adopting upper inlet and down inlet is conductive to air convection, not only energy-saving but also avoiding place doesn’t radiating. So it can ensure the security of equipment heat radiating. Meanwhile, due to compressor build inside, it can improve the operation environment and lengthen the life of compressor, and antitheft.

RS485 standard communication protocol and support centralized control and remote monitoringRecycle operating as standard, power memory, autostart when power on to meet requirement of unmanned operation;Built-in protection function and malfunction alarm function to ensure reliable and stable operation;Multi-unit set of control design to avoid running conflict.

High temperature outlet air to avoid the threat of condensation and provide safe and reliable environment;

Full removal of heat load of room, eliminating local hot spots;

The sensible heat ratio in standard condition more than 80%, energy efficiency increase 20% relative to common base conditioner;

With freecooling function. In cooling or Auto mode, freecooling function auto switch. When outdoor ambient temperature lower than 20°C, and room temperature higher than 16°C, 100% freecooling, turn off the com-pressor and directly cooling by cold outdoor air. Also can partly freecooling and compressor cooling. So it's high energy saving;

Applicable to a variety of areas, reliable and stable;

Backup operation, increase of service life. And easy to maintenance;

Down front supply, top return

Copper tube and Aluminum fin

Precision Air Conditioners 18Precision Air Conditioners17

Midea packaged thermostat precision air conditioner, integrated structure design, without outdoor unit hang-ing, suitable for laboratories, testing rooms, storage rooms and high-end building which is not suitable for outdoor unit installation

High temperature outlet air to avoid the threat of condensation and provide safe and reliable environment;

Full removal of heat load of room, eliminating local hot spots;

The sensible heat ratio in standard condition more than 80%, energy efficiency increase 20% relative to common base conditioner;

With freecooling function. In cooling or Auto mode, freecooling function auto switch. When outdoor ambient temperature lower than 20℃, and room temperature higher than 16℃, 100% freecooling, turn off the com-pressor and directly cooling by cold outdoor air. Also can partly freecooling and compressor cooling. So it's high energy saving.

Built-in pressure protection, power protection, overload protection function and malfunction alarm function. Ensure the system operate stably and reliably;
