Abstract

The invention discloses an ammonia working medium liquid distributor which comprises a liquid distributing pipe and a box-like body, wherein the body is arranged horizontally, a top plate is a gas homogenizing plate, and a bottom plate is a liquid distributing plate; the liquid distributing pipe comprises a vertical pipe, a collecting pipe and a plurality of branch pipes; the collecting pipe and the branch pipes are arranged in an inner cavity of the body, and the branch pipes communicate to the collecting pipe, separately; an upper liquid distributing hole is formed in each branch pipe; a gapis reserved between each upper liquid distributing hole and the gas homogenizing plate; the vertical pipe is arranged vertically, the upper end of the vertical pipe is a liquid inlet, and the vertical pipe penetrates above the body and communicates to the liquid distributing plate and the collecting pipe; a plurality of gas homogenizing holes are formed in the gas homogenizing plate; and a plurality of lower liquid distributing holes are formed in the liquid distributing plate. According to the ammonia working medium liquid distributor disclosed by the invention, an ammonia working medium isuniformly distributed in an evaporator and the storage capacity of the ammonia working medium in the liquid distributor can be reduced.

Description

technical field [0001] The invention relates to an ammonia working medium liquid distributor, which belongs to the technical field of refrigeration. Background technique [0002] At present, falling film evaporators using freon working fluid are widely used in air conditioners and process chillers because of their advantages in high heat exchange efficiency, low working fluid charge, and cost. [0003] In recent years, with the pressure of environmental protection, the application of freon working fluid has been suppressed, and the application of natural working fluid has been widely promoted, especially the application of ammonia working fluid has attracted much attention. The application of ammonia working fluid is based on small charging volume, so it is necessary to develop falling film evaporator for ammonia working fluid, and the key technology of falling film evaporator lies in the design of liquid distributor for ammonia. [0004] Compared with the liquid distributo...
