The 3 primary functions of HVAC (heating, ventilation and air-con) are interrelated, especially when necessary to provide thermal convenience and a standard of indoor air high quality.
It can be found on two-phase heat pumps or any systems that includes a backup heater for example an auxiliary electric heater. ODT ensures the power-starvation backup heater only activates when the surface temperature is simply too cold.
If the damaging stress is critical, the exhaust system gained’t do the job any more. Hence, MUA is required to make sure the home gained’t be became a vacuum Room and the exhaust system can continuously perform.
