Embodiment Construction

[0030] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, in each figure, the same or similar reference numerals are assigned to mutually identical or corresponding components, and overlapping descriptions will be omitted.

[0031] First, refer to figure 1 The absorption heat pump 1 according to the embodiment of the present invention will be described. figure 1is a schematic system diagram of the absorption heat pump 1 . The absorption heat pump 1 includes an absorber 10 , an evaporator 20 , a regenerator 30 , a condenser 40 , and a control device 90 as main components for performing an absorption heat pump cycle. A cooling water heat exchanger 51 serving as a cooling water temperature booster for heating the cooling water supplied to the condenser 40 is also provided. In the second type of absorption heat pump, a gas-liquid separator (not shown) is provided for separating gas-liquid from the heated medium when ...

Abstract

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.

Description

technical field [0001] The present invention relates to an absorption heat pump, and particularly to an absorption heat pump capable of handling low-temperature cooling water. Background technique [0002] There is an absorption heat pump as a heat source machine that acquires more heat energy than the driving heat source or a heated medium whose temperature is higher than that of the driving heat source. The former is called the first type of absorption heat pump, and the latter is called the second type of absorption heat pump. Such an absorption heat pump mainly includes an evaporator for evaporating a refrigerant liquid, an absorber for absorbing refrigerant vapor in a solution, a regenerator for detaching the refrigerant from the solution, and a condenser for condensing the refrigerant vapor. Absorption heat pumps utilize a heat rejection source that has heat rejection energy. [0003] Patent Document 1: Japanese Patent No. 4648014 ( figure 1 Wait) [0004] In parti...
