Large Air Volume Precision Air Conditioner with 40-90KW Cooling Capacity and

Product Introduction

Precision air conditioners are designed for data centers, computer rooms, and network centers. All series of precision air conditioners for computer rooms use modular energy-saving planning principles, and different types of special precision air conditioners are announced according to different users. The electronic equipment in the communication room releases a lot of sensible heat. According to the characteristics of the room, the high sensible heat ratio of 0.9 or more is achieved. When used in the environment of the computer room, it consumes about 20-30% of the energy consumption compared with ordinary comfort air conditioners, and thus avoids excessive Dehumidification and air supply are foggy.

Single/double refrigeration circuit design, centralized condensation scheme can be selected;

• High reliability, high energy saving rate, high adaptability, low cost throughout life
• The air-conditioning unit adopts a modular design, the compressor and evaporator of a refrigeration system are in the same module, and the transportation and handling module is disassembled.
• The indoor fans are equipped with EBM/Xerox Bai and other brand EC fans as standard, and the fan system saves more than 30% energy than conventional air conditioning units.
• The same external pressure requirement. The inner fan can be operated with stepless speed regulation, and the temperature difference between the supply and return air, the temperature of the return air and the temperature of the outlet air can be selected for control.
• Standard EEV dual electronic expansion valve, low-load dehumidification
• Large area V-shaped evaporator, high air volume, high sensible heat ratio
• Large humidification capacity, suitable for poor water quality, low maintenance
• Frequency conversion series units are equipped with oil separator as standard
• The power consumption per 1kg/h of humidification should not exceed 0.8kW to achieve energy-saving operation.
