The maintenance of a stable temperatures and humidity control are key design challenges in these applications, since they are used in environments where ambient temperatures often vary significantly during the day. A computer room air conditioning (CRAC) unit is a device that monitors and maintains the temperature, air distribution and humidity in a network room or data center.

CRAC units are replacing air-conditioning units that were used in the past to cool data centers. According to Industrial Market Trends, mainframes and racks. CCU also commonly know as Close control air conditioner or Computer room air conditioner (CRAC) or Server room air conditioner. Close Control Unit Or Precision Air conditioner. Close control unit not only maintains temperature but also humidity together to precise set level.

Each CCU shall consist of an indoor evaporator module and a condensing module. The evaporator shall be installed against a wall inside the computer room.

Fan Coil Unit A fan coil unit (FCU) is a device that uses a coil and a fan to heat or cool a room without connecting to ductwork. Indoor air moves over the coil, which heats or cools the air before pushing it back out into the room.

FCU is an indoor unit with small tonage capacities used with central air conditioning systems such as chillers system. AHU is an indoor and also can be used as outdoor also used with central air conditioning systems such as chillers system but have a wide range of capacities having a great static pressure of fans to deliver the air through air ducts to big cooling zone areas. The CCU is connected to the DME engine control unit , and this signal enable the CCU to stop the fuel supply being cut off on the overrun.

This is only done when heat is needed in the cabin. AHU and FCU are both included in the HVAC system. The latter is an acronym that describes multiple systems of heating, ventilating and air conditioning. AHU, completely known as air handling unit is different from FCU or the fan coil unit. AHUs are usually connected to a central HVAC system whereas an FCU can function or be installed itself.
