overflow tank

Exceptional Features:

  • Designed and manufactured according to TCVN, ISO, ASME Code and other regulations.
  • Welded automatically, tested for durability and all welds are 100% ultrasonic tested with a certificate of conformity
  • We are allowed to issue pressure vessel resumes as authorized by authorities.

Description

  • The overflow tank is used to maintain a stable low-pressure liquid supply to the evaporator to meet the required volume of the load.
  • In addition, the overflow tank is also responsible for separating liquid for the suction vapor to the compressor.
  • Designed to be horizontal or vertical.

Technical details

  • In accordance with TCVN 6153-6156:1996; TCVN 6104:1996: ISO 5149:1993 and ASME Code
  • Dimensions and thickness designed according to standards and needs of use.
  • Material: Body and bottom of the tank use carbon steel.

Pipes connected to the tank: Pressure cast steel pipe

Working principle

  • The overflow tank is used in liquid flooded throttling refrigeration systems. After throttling, cold gas is supplied to the overflow tank, thanks to the hydrostatic head of liquid gas entering the indoor unit to perform heat exchange. After evaporation, the refrigerant vapor is returned to the overflow tank to separate the liquid for the suction vapor to the compressor, preventing hydraulic shock. The tank is equipped with a float valve to control the level of liquid gas contained in the tank.

Specifications

  • Design according to system capacity.
