Product Introduction

The cooling system occupies a very important position in the MDC system. In response to the characteristics and needs of the MDC, Kotohira has carefully created an innovative and energy-saving GentleAir series, which covers rack-mounted precision air conditioners and in row precision air conditioners. This series is suitable for modular data centers and form modular solutions

Product classification and capacity

◆ Rackmount Installation capacity: 3.5/5.9/8.6/12.8kw

Rack-mounted air conditioners features

◆ Frequency conversion compressor, adjustable cooling capacity, precise control of

internal temperature, avoid shortening the life of the compressor caused by frequent start and stop of the compressor.

◆ Dedicated precision air-conditioning control system, supports dynamic fault alarm and protection, monitoring  data upload and remote monitoring management.

◆ Rack-mounted modular structure and supports modular expansion

◆ R410A environmentally friendly refrigerant, green and no ozone layer damage.

◆ Copper pipes are connected by quick joints, supporting upper and lower connection.

◆ Adopt EC fans and dynamically adjust air volume

◆ The flat air outlet can be installed in any U position inside the cabinet.

In row air conditioners features

Dynamic energy-saving

◆EC fan with stepless speed regulation automatically match the air volume demand of the server

◆ Inverter compressor, cooling output automatically matches server thermal load changes

◆ Outdoor fan is driven by variable frequency stepless speed regulation, the wind speed is automatically adapted to the change of ambient temperature

◆ Electronic expansion valve control, automatically matching server thermal load changes

◆ The air supply temperature control function ensures that the server air intake temperature meets the design range, which is safe, reliable, energy-saving and environmentally friendly.

◆ Standard configuration includes 1 supply air temperature sensor and 1 return air temperature and humidity sensor, and 16 external temperature sensors are optional.

◆ 37℃ return air temperature, 100% sensible heat rate design, energy saving and environmental protection.

◆ R410A environmentally friendly refrigerant.

Easy to install and maintain

◆ 100% front and rear maintenance

◆ Support up and down connection, convenient for on-site pipeline layout, and can be installed with or without raised floors

◆ Built-in refrigerant pressure sensor and refrigerant temperature sensor, users can check the high pressure and low pressure of the system in real time, convenient for system problem diagnosis

◆ The return air temperature, liquid pipe temperature, subcooling degree, superheating degree of the refrigeration system and the speed percentage of the compressor and the outdoor fan. Facilitate equipment maintenance and operation monitoring to ensure reliable operation of equipment

◆ In order to ensure the stable and reliable operation of the refrigeration system, the refrigeration system of precision air-conditioning equipment is equipped with an oil separator as standard
