Absorption plate for an air-conditioner

摘要

The invention relates to an absorption plate for a vehicle air-conditioner, through which a flow of absorbent fluid (110) passes, said fluid flowing along at least one exchange surface (130), the exothermic absorption of a coolant occurring through said at least one exchange surface (130) by increasing the concentration of the coolant in the absorbent fluid (110), the plate comprising, along said at least one exchange surface (130), a means (150) for rendering the temperature of the flow of absorbent fluid uniform, characterized in that the means (150) for rendering the temperature uniform is a separate turbulence means for said at least one exchange surface (130), and increases the turbulence of the flow of absorbent fluid (110) along said at least one exchange surface (130).

主权项

1. An absorption plate for an air conditioner for a vehicle, traversed by a flow of absorbing fluid flowing along at least one exchange surface, whereby the exothermal absorption of a refrigerating fluid by the absorbing fluid takes place by the at least one exchange surface by increasing a concentration of the refrigerating fluid in the absorbing fluid, the absorption plate comprising an inlet member though which absorbing fluid enters the absorption plate, an outlet member through which absorbing fluid exits said absorption plate, and first and second side member extending between said inlet and outlet members; said inlet, outlet and side members defining a flow path for absorbent fluid; at least one of said side members comprising said at least one exchange surface; said at least one exchange surface comprising a grid through which a refrigerant can pass to be absorbed by the absorbing fluid; said absorption plate further comprising means positioned along the at least one exchange surface for homogenizing the temperature of the flow of absorbing fluid and the concentration of refrigerant in the absorbing fluid, characterized in that the homogenization means is distinct from the at least one exchange surface; said homogenization means comprising a buffer reservoir which divides said flow path into at least a first portion and a second portion below said first portion; said buffer reservoir comprising:
an entrance for capturing the flow of absorbing fluid flowing along the at least one exchange surface from said first portion of said flow path; a reservoir having for mixing absorbing fluid, said reservoir having a bottom surface; and at least one outlet in communication with said second portion of said flow path, said at least one outlet being arranged in said bottom surface of said reservoir for distributing the flow of absorbing fluid mixed on the at least one exchange surface to said second portion of said flow path.
