VARIABLE CAPACITY AND AIR FLOW ROOFTOP SYSTEM

  • Single zone VAV, or single zone variable air volume, is an HVAC application in which the HVAC unit varies the airflow at constant temperature to provide space temperature control.
  • A constant volume HVAC unit supplies constant airflow with variable temperature to provide temperature control.

Benefits of VAV system

  • A single zone VAV system will operate at a lower fan speed than a constant volume system, resulting in less fan energy consumption.
  • With the modulation capabilities of both the fan and compressor a single zone VAV system can provide precise temperature control and additional passive dehumidification.
  • The modulation capabilities of the compressor reduce the amount of compressor on/off cycling, reducing wear on the compressor and providing greater energy savings than hot gas bypass systems.
  • Lower fan speeds reduce the amount of sound produced by the supply fan.
  • With the entire modulating control for part load operation provided within the HVAC unit, a single zone VAV system is simple to install, set up and maintain.
  • Electrical or naturel gas heating option
  • Heat-Pump

The heat recovery units basically operate with the principle of adding energyto the fresh air that has been ventilated from the return air. In order toventilate a room using a heat recovery unit, when the cooled air is thrownout, the incoming fresh air is cooled in the summer operation. In winteroperation, when hot air is thrown out, fresh air is heated. Thus, energy savings of up to 83% are obtained.

Efficient and effective humidity control

With the help of optional reheat coil dehumidified and subcooled air coming through evaoperator coil is reheated up to conditioned space temparature and released to space.

Reheat coilis heated by hot gas coming from the compressor. since no external heat source is required the total humidifiying efficiency is superior to other competiors.
