Absorption heat pump

Japanese Patent JP6297377

B2

The invention provides an absorption heat pump which can operate even though when supplied cooling water is relatively low in temperature. The absorption heat pump comprises an absorber, a regenerator, a condenser, a cooling water warmer, and a controller. The absorber makes a solution absorb steam of a refrigerating fluid to become a dilute solution, and a heated medium is heated by using absorption heat which is generated when the solution becomes the dilute solution. The regenerator heats the dilute solution by using a heat source medium, and refrigerating fluid steam is generated from the dilute solution, so that the solution becomes a strong solution whose concentration is higher than that of the dilute solution. The condenser uses the refrigerating fluid steam which is generated in the regenerator by cooling water to capture heat to perform condensation on the refrigerating fluid steam. The cooling water warmer gives heat to the cooling water which is supplied to the condenser, the heat not being the heat captured by the refrigerating fluid steam, so that the cooling water is heated. The controller regulates temperature rise amount in the cooling water warmer, and maintains concentration of the strong solution not to exceed a specified concentration.
