    • An absorption refrigeration system incorporating a novel solution flow control is disclosed. The solution flow control includes a sensor, preferably in the form of a float which senses the level of the solution in the absorber of the system. The signal from the level sensor is utilized to position a valve for controlling the flow of weak solution in such a manner that the solution flow increases/decreases as the level of the solution in the absorber decreases/increases. The solution control not only provides improved efficiency of the refrigeration system but also protects the system from the risk of crystallization of the solution. In one embodiment, a compact solution control is fully enclosed by an air-tight shell of the absorber and comprises a float, a rod mechanically and drivingly coupling the float with a solution valve so that the buoyancy of the float directly positions the valve. This arrangement does not need to meet the requirement of having an air tight structure and assures a long life in use.
    • 公开了一种结合新型溶液流控制的吸收制冷系统。 溶液流控制包括传感器,优选地以浮子的形式感测系统的吸收器中的溶液的水平。 来自液位传感器的信号用于定位用于控制弱溶液流动的阀,使得溶液流随吸收剂中溶液的水平降低/增加而增加/减少。 解决方案控制不仅提供了制冷系统的改进效率,而且还保护系统免受溶液结晶的风险。 在一个实施例中,紧凑的解决方案控制由吸收器的气密外壳完全封闭,并且包括浮子,杆机械地驱动地将浮子与溶液阀连接,使得浮子的浮力直接定位阀。 这种布置不需要满足具有气密结构的要求并且确保使用寿命长。
