Single-effective absorption refrigerating machine

Abstract

The invention discloses a single-effective absorption refrigerating machine, which consists of an absorption chamber and an evaporation chamber independent from each other. The absorption chamber is an airtight space, the interior of the space is divided into an upper space and a lower space communicated with each other, the lower space is used for accommodating a liquid-state refrigerant; and the upper space is a steam absorption space in which a coil pipe is arranged, and the structure of the coil pipe is that a hydrophobic micropore film is compounded on a metal pipe; a generation chamber is an airtight space which is formed by communicating a steam generator and a steam condenser, the steam generator is a coil pipe, and the structure of the coil pipe is that the hydrophobic micropore film is compounded on the metal pipe, and an interlayer channel between the metal pipe and the film pipe is a separate closed channel; vapor or hot water for heating flows in the metal pipe while absorbent dilute solution flows in the interlayer; and the absorption chamber is connected with the generation chamber through a heat exchanger.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a single-effect absorption refrigerator. Background technique [0002] Under certain conditions, microporous hydrophobic membranes can selectively pass through vapor and prevent liquid from passing through. This feature has been widely used in separation processes such as pervaporation and membrane distillation. Vapor exists at the interface between the liquid and the microporous hydrophobic membrane. When there is a large difference in vapor pressure on both sides of the membrane, the vapor will be driven to migrate from the high-pressure side to the low-pressure side. [0003] The existing absorption refrigerators are mainly lithium bromide refrigerators. The unit is in a negative pressure state when it is working inside, so cavitation is prone to occur when the dilute solution is pumped from the absorption chamber to the generation chamber, so it is necessary to use a special shielded pump w...

Problems solved by technology

The unit is in a negative pressure state when it is working inside, so cavitation is prone to occur when the dilute solution is pumped from the absorption chamber to the generation chamber, so it is necessary to use a special shielded pump with a high cavitation allowance, which is one of the reasons for the increase in the cost of the unit Key factor
