Vacuum Exhaust Constant Pressure Unit

The working principle of the vacuum exhaust constant pressure unit is based on Henry's Law, which states that a certain amount of gas dissolves in water at a specific temperature and pressure. When the temperature increases or the pressure decreases, the amount of dissolved gas in the water decreases.

The unit creates a vacuum to release free and dissolved gases from the water, which are then expelled from the system through an automatic exhaust valve. The degassed, unsaturated water absorbs gases from the system to achieve gas-water balance, ensuring stable and safe system operation.

The functions of the vacuum exhaust constant pressure unit include:
Constant Pressure: Controls the system pressure within a set range to ensure stable system pressure.
Vacuum Exhaust: Removes free and dissolved gases from the system through a vacuum state.
Water Replenishment: Automatically replenishes water to the system to ensure sufficient water volume.
Water Softening: For units equipped with water softening functionality, it treats the incoming water to soften its quality.

The application areas of the vacuum exhaust constant pressure unit include:
Heating Systems: Suitable for heating systems in hotels, hospitals, public venues, office buildings, etc., ensuring stable operation of the heating system.
Refrigeration Systems: Maintains pressure stability in central air conditioning systems to ensure effective cooling.
