In April, at China Refrigeration and Heating 21 (CRH-2021), Midea presented a line of several new series of high efficiency precision air conditioning systems (industrial cabinet precision fan coil units). The main purpose is to work in data centers, in the network of a refrigeration station with a chiller (coolant - water / glycol).
1) In-Array Series
Application scenarios: IDC data center, sealed heat / cold channel.
Energy saving: All In-Array precision air conditioners with DC inverters have a pPUE of only 1.008. It saves 71.7% more energy than the In-Row Series.
Space-saving: The air conditioner is located under the racks, which have realized air supply through the raised floor, which saves space in the control room. At the same time, the usable area of the control room is increased by 18.2% compared to the In-Row series, and the economic income is from 18% +.
Factory production: The equipment is manufactured in the form of modules. Installation of water pipes, connectors, etc. transferred to factory assembly, installation efficiency increased by 90%.
In-Array Series + High Efficiency Centrifugal Chiller + Free Cooling + M-BMS = Hardware Implementation PUE 1.25
2) In-Room Series
Application Scenarios: IDC data centers, cloud computing, transportation, energy, communications and other medium-sized and large-scale applications.
Equipment features:
- Air filter standard - G4, improved dust cleaning;
- "V / A" type evaporator, highly efficient heat exchange;
- Modular design, easy to assemble / disassemble;
- Safe and reliable PTC heater, low thermal resistance, high heat transfer efficiency;
- New design of rotary electric control box, easy maintenance and repair;
- Highly efficient humidifier;
- High efficiency EC fan, recessed design.
Modular Design: Frame type design, flexible combination and easily expandable system.
Easy installation: Key equipment components are pre-integrated into the factory installation to reduce onsite installation work. Standardized design, easy to transport.

3) In-Row Series
Application Scenarios: IDC data centers as well as switchgear rooms, local high heat dissipation rooms, high heat density rooms.
Equipment features: In-Row precision air conditioners are row-level chilled water temperature control devices. This is an air terminal unit installed in the control room. It usually forms a complete cooling system including water heat exchanger, water pump, chilled water piping, etc. It also uses an EC fan, usually installed in the equipment panel row, next to the heat source, providing medium to high heat dissipation solutions. density.
Increased reliability:
-
Fan duplicating each other. Online service capability, without interrupting cooling while replacing a failed fan.
-
Intelligent motor resource management. Balancing the operating time of each unit, prolongs the service life of the equipment.
-
Professional selection and design of the device.
-
Redundant power supply (optional). When power is lost on one circuit, it automatically switches to the other (redundant) power supply (circuit).
Energy saving:
- Highly efficient components. DC fan EC. Proportional built-in water flow regulator with water valve. Moistening with wet film (optional).
- Dry heat exchanger design. No energy consumption for dehumidification and humidification.
- Effective matching. Compatible with high efficiency Midea chillers. M-BMS connection management.
Easy access:
- 7-inch touch screen. Displays the operating mode and status of the device.
- Convenient expert-level troubleshooting.
- Full access and serviceability from both the front and rear.
