Vacuum exhaust constant pressure unit

Category： Environmental Protection Equipment

The working principle of the vacuum exhaust constant pressure unit is based on Henry's law, which states that a certain amount of gas is dissolved in water at a certain temperature and pressure. When the temperature increases or the pressure decreases, the amount of gas dissolved in the water will decrease. The unit generates a vacuum to release free and dissolved gases in the water, which are then discharged from the system through an automatic exhaust valve. The unsaturated water after degassing will absorb the gas in the system, seeking gas water balance to ensure stable and safe operation of the system.

The functions of the vacuum exhaust constant pressure unit include:
Constant pressure: Control the system pressure within the set range to ensure constant system pressure.
Vacuum exhaust: Degassing free and dissolved gases from the system through a vacuum state.
Hydration: Automatically replenish water to the system to ensure sufficient water supply.
Soft water: For units with soft water function, water quality softening treatment can be applied to the incoming water.
The application areas of vacuum exhaust constant pressure unit include:
Heating system: Suitable for heating systems in hotels, hospitals, public welfare venues, office buildings, etc., to ensure the stable operation of the heating system.
Refrigeration system: In the central air conditioning system, maintain stable system pressure to ensure cooling efficiency.
