Open-type lithium bromide unit for synchronous cooling and heating

Abstract

The invention discloses an open-type lithium bromide unit for synchronous cooling and heating. The technical scheme is that the open-type lithium bromide unit for synchronous cooling and heating includes a lithium bromide solution circulation unit for cooling, and the lithium bromide solution circulation unit includes a low-pressure flash device for low-pressure evaporation of the lithium bromidesolution, a liquid storage device for storing the lithium bromide solution, and a generation pump for transferring the lithium bromide solution in the liquid storage device to a flash tank and furtherincludes high-pressure steam conversion unit for converting steam condensate into high-pressure steam, an injection assembly which communicates with a lithium bromide storage tank and the high-pressure steam conversion unit and is used for accessing the high-pressure steam to inject the low-pressure steam in a flash tank, the high-pressure steam conversed by the high-pressure steam conversion unit is accessed to the injection assembly to inject the evaporated low-pressure steam by using the injection assembly, meanwhile the continuous low-pressure state in the flash tank is achieved, and theopen-type operation of the lithium bromide unit is completed without the high tightness of the traditional lithium bromide unit.

Description

Technical field [0001] The invention relates to the field of lithium bromide units, in particular to an open-type lithium bromide unit for synchronous cooling and heating. Background technique [0002] In lithium bromide refrigeration, water is used as a refrigerant and lithium bromide is used as an absorbent, which is a common refrigeration method. [0003] Because lithium bromide itself has a high boiling point and is extremely difficult to volatilize, it can be considered that the vapor on the surface of the lithium bromide saturated solution is pure water vapor; at a certain temperature, the saturation partial pressure of water vapor on the surface of the lithium bromide aqueous solution is less than the saturation partial pressure of pure water ; And the higher the concentration, the lower the partial pressure of water vapor saturation on the liquid surface. Therefore, under the same temperature conditions, the greater the concentration of the lithium bromide aqueous solution...
