Document Type and Number:
Japanese Patent JP6992234
Kind Code:
B2
Abstract:
The purpose of the present invention is to stably operate an absorption refrigerator. This liquid composition measurement device 65 is for measuring the liquid composition of a liquid mixture used in an absorption refrigerator 1 comprising: a regenerator 10 that uses, as a three-component type working medium, a liquid mixture of water, lithium bromide, and 1,4-Dioxane and heats and evaporates the working medium; a condenser 20 for cooling and condensing the steam mixture evaporated by the regenerator 10; an evaporator 30 for vacuum evaporating the liquid mixture condensed by the condenser 20 and obtaining cold energy using the heat of vaporization of the liquid mixture; and an absorber 40 for causing lithium bromide to absorb the steam mixture generated by the evaporator 30. The liquid composition measurement device 65 has a first measurement unit 651 to third measurement unit 653 for measuring m − 1 different types of physical properties, and the liquid composition measurement device 65 calculates the liquid concentration or liquid composition of the working medium, which has m types of liquids mixed therein, on the basis of the m − 1 different types of physical properties measured by the first measurement unit 651 to third measurement unit 653.
