Often installed in the commanding heights or elbows, etc., to exclude excess gas pipeline, pipelines to improve the efficiency and reduce energy consumption. HVAC, HVAC Systems During operation, the numerous adverse effects of gases (such as hydrogen, oxygen, etc.) released by water during heating can damage the system and reduce the thermal effects. If these gases can not be discharged promptly, Adverse consequences. Such as: corrosion caused by oxidation; the formation of airbags in the radiator; unbalanced hot water circulation is not smooth, so that some radiators do not partially heat; noise when the pipe runs with gas; vortex phenomenon circulating pump.
