Abstract

The invention relates to the technical field of refrigeration equipment, and discloses an air supply tank for an air suspension system. The air supply tank comprises a body, a first cavity and a second cavity; the body is provided with a liquid supply port and an air outlet; the liquid supply port is used for communicating with a liquid supply pipe; the air outlet is used for communicating with an air outlet pipe; the first cavity is formed in the body, communicates with the liquid supply port and the air outlet, and is used for converting a liquid refrigerant into a gas refrigerant; the second cavity is arranged in the body and can be filled with gas; the volumes of the first cavity and the second cavity are variable; and when the air supply tank works normally, the pressure of the second cavity and the pressure of the first cavity are balanced; According to the air supply tank, the second cavity is arranged, and the pressure of the first cavity and the pressure of the second cavity are balanced during normal work, so that the air supply pressure of the air supply tank can be stable; the refrigerant filling amount is small; only an electric heater with small power needs to be used; upstream circuit electric devices with large specifications do not need to be arranged; and the production cost of an air suspension system is effectively reduced.

Description

technical field [0001] The present application relates to the technical field of refrigeration equipment, for example, to an air supply tank for an air suspension system. Background technique [0002] When the air-suspended centrifugal compressor used in the chiller is working, its aerostatic bearing needs to provide a stable compressed air with a certain pressure from the outside to keep the shaft diameter supported by the bearing stably suspended near the center of the bearing, ensuring that the journal No contact wear with the bearing bush. [0003] In order to realize the stable pressure supply of the air suspension centrifugal compressor, the existing air supply tank needs to be filled with a large amount of refrigerant for power supply, heating, gasification and pressurization; secondly, a high-power electric heater needs to be configured for rapid gasification of the refrigerant, and timely replenishment The pressure drop caused by the gas used by the bearing will in...
