Description

Technical Field

[0001] The invention relates to the technical field of chillers, and in particular to an adjustable built-in gas collecting device for a condenser and a condenser. Background Art

[0002] In a centrifugal chiller system with negative pressure working medium, since the internal pressure of the unit is lower than the atmospheric pressure, the outside air will leak into the evaporator and enter the condenser to become non-condensable gas. When the unit is operating normally under a certain working condition, the pressure of the entire condenser cavity is equal, but since the mixed gas of the refrigerant and non-condensable gas after the secondary compression of the compressor enters the condenser through the exhaust port, the gaseous refrigerant is condensed into liquid through the copper tube heat exchange and collected at the bottom of the condenser. Due to the impact of the airflow at the exhaust port, the non-condensable gas is constantly "squeezed" to both ends of the exhaust port. As the running time of the unit increases, the non-condensable gas is constantly moved to both ends of the exhaust port due to "squeezing". Finally, the farther away from the exhaust port, the higher the non-condensable gas content. In the prior art, a pipeline is usually used to extract the non-condensable gas from the inside of the condenser, but due to the fixed setting of the pipeline, the extraction position cannot be adjusted according to the distribution of the non-condensable gas. Therefore, the non-condensable gas discharge effect is poor. Summary of the invention

[0023] In the above embodiment, the adjustment mechanism 30 includes a telescopic rod 31, and the gas collection bag 20 is connected to the gas extraction assembly 10 through the telescopic rod 31. The telescopic rod 31 can adjust the position of the gas extraction assembly 10 by extending or shortening. The gas collection device of the present invention can adjust the position of the gas extraction assembly 10 in the condenser 60 by extending or shortening the telescopic rod 31, which can greatly improve the extraction efficiency of non-condensable gas and facilitate operation.

[0024] In the above embodiment, the telescopic rod 31 has a transverse telescopic section 311 and a longitudinal telescopic section 312.

In combination with the rotation of the gas collecting bag 20, the gas extraction component 10 can be moved to any position within its range, which can greatly improve the extraction efficiency of the non-condensable gas and is more convenient and flexible in operation.

[0025] In another embodiment, the adjustment mechanism 30 includes: a telescopic rod 31, the telescopic rod 31 is connected to the air extraction component 10, and the telescopic rod 31 can adjust the position of the air extraction component 10 by extending or shortening.
