Degassing unit for a liquid in a pipe system, comprises a membrane with a vacuum pump located on the low pressure side

摘要

An arrangement for degassing the liquid in a (non) pressurised pipe system, esp a heating and cooling installation, comprises a membrane. The gases permeate or diffuse out of the installation via the membrane. A vacuum pump (9) is located on the low pressure side of the membrane (7), and its power and/or operating period is controlled so the gas content remains below a predetermined value.
