New air control unit controls include: supply air temperature control, air relative humidity control, frost control, CO2 concentration control, and various interlock content. If the new commitment to consider indoor air unit loads (eg DC-type units), but also to control the room temperature (or indoor relative humidity). 1. supply air temperature control Supply air temperature control which means the fix air temperature control, the applicable conditions are usually the fresh air unit is to meet the health requirements rather than a burden indoor indoor load to use. Thus, the control over the entire time, which is to maintain a constant supply air temperature principle. Since the winter and summer indoor requirements are different, therefore in winter and summer air temperature should be different requirements. That is, when the new air unit set supply air temperature control, two control values ??throughout the year - winter and summer control value control value, and therefore must be considered controller winter and summer conditions of the conversion. When the supply air temperature control, usually summer water cooling coil control, winter control steam flow hot water or steam coil coil. In order to facilitate the new air unit management role, the temperature sensor is generally located in the room where the air tube inside the unit. Fresh air unit and an air conditioning unit difference: fresh air unit is used to deal with new wind in the shape of a large building, and most of the new air unit is used together with the fan coil, fan coil + new fans and air conditioners in fact almost the same; Under normal circumstances, the air conditioner itself offer new outlet new air handling units, fresh air to ensure indoor air quality new air handling units, and added indoor ventilation. Since no new fan coil outlet, it is necessary to provide a new fan. New air handling units provided through the new air handling and fan coil processed through the return air, or is first mixed and then treated by the fan coil, and then into the room. It proposed to establish and improve the safe operation of the operation and management system. Fresh air unit also deactivated at night using fixed water flow or thermostat automatic control valve to open or provided to ensure that the temperature of the electric heating means fresh air unit heaters. Fresh air units in winter when fresh air units to regular inspections principle, track weather changes, cold weather should arrange commissioning and maintenance of air conditioning systems, air conditioning system in order to ensure safety of operation.
