ABSORPTION TYPE COLD HEAT GENERATOR

PURPOSE: To detect reliably an upper bound position or a lower bound position of ice portions of an ice slurry by a method wherein oscillation type liquid level meters for detecting an upper bound position and a lower bound position of ice portions of an ice slurry are disposed in a cold heat tank. CONSTITUTION: When cold heat is generated, an absorption cycle is actuated. In such an absorption cycle, water flowing through a heat transfer pipe 1a in an evaporator 1 is cooled, and a temperature of the cold water thus cooled is rapidly lowered to produce ice. As a result, the cold water in a cold heat tank 6 turns into an ice slurry A including ice. When a predetermined amount of the ice slurry A is stored in the tank i.e., when the ice portions of the ice slurry A are detected by both level meters of a first and a second oscillation type level meters 7, 8, both detection signals are sent to a controller 11, whereby it is judged that a predetermined amount of the ice slurry A has been stored. Thereupon, an OFF signal is outputted from the controller 11 into a controller 12 for a heating burner 3, and the actuation of the absorption cycle is stopped.
