METHOD AND DEVICE FOR SWITCHING COOLING/HEATING MODE IN ABSORPTION TYPE WATER COOLING AND HEATING MACHINE

摘要

PROBLEM TO BE SOLVED: To prevent the self-boiling of bromide lithium solution, reserved in an absorber, upon switching the heating mode operation of a bromide lithium absorption type water cooling and heating machine into the cooling mode operation of the same. SOLUTION: A conventional bromide lithium absorption type water cooling and heating machine is provided with a heat exchanger 21 for cooling bromide lithium solution (a radiator 26 can be provided). The bromide lithium solution (shown by parallel oblique lines in a diagram), whose temperature is raised during heating mode operation, is cooled upon the switching operation of heating into cooling by guiding the same into the heat exchanger 21 for cooling the solution. According to this cooling, the self-boiling of the bromide lithium solution can be prevented.
