Title:
SOLUTION COMPONENT MEASURING APPARATUS OF ABSORPTION FREEZING MACHINE, AND SOLUTION COMPONENT MEASURING METHOD
Document Type and Number:
Japanese Patent JP2019027627
Kind Code:
A
Abstract:
To realize stable operation of an absorption freezing machine.SOLUTION: There is provided a solution component measuring apparatus 65 for measuring solution component of mix solution used in an absorption freezing machine 1 using liquid in which water, lithium bromide and 1,4 dioxane are mixed as working medium of 3 components and comprising: a recycling chamber 10 heating the working medium to evaporate it; a condenser 20 cooling and condensing the steam mixture evaporated in the recycling chamber 10; an evaporator 30 evaporating the mix solution condensed by the condenser 20 under reduced pressure so as to obtain low-temperature due to vaporization heat; and an inhalator 40 bringing the steam mixture generated by the evaporator 30 to be absorbed by the lithium bromide. A first measuring part 651 to a third measuring part 653 are further provided for measuring m-1 types of different physical properties. The solution component measuring apparatus 65 calculates solution concentration or solution component of the working medium in which m types of liquid are mixed based on the m-1 types of different physical properties measured by the first measuring part 651 to third measuring part 653.SELECTED DRAWING: Figure 1
