Embodiment approach 1

[0045] figure 1 It is an explanatory diagram showing the concept of Embodiment 1, figure 2 yes figure 1 Enlarged view of main parts. The composite absorption heat pump device of Embodiment 1 is a vehicle-mounted device, such as figure 1 As shown, there are regenerator 3 (regeneration part 2 and separation part 1), condenser 4, evaporator 5, absorber 6, cooler 7, and exhaust gas flow path part 73.

[0046] The exhaust gas passage portion 73 is connected to the exhaust gas side of the engine 72 . Exhaust gas generated by the engine 72 flows through the exhaust gas passage portion 73 . The exhaust gas flow path portion 73 communicates with the regeneration portion 2 constituting a part of the regenerator 3 in the absorption heat pump. Further, on the front side of the engine 72 (more specifically, the front side in the traveling direction of the vehicle), a cooler 7 having a radiator 70 and a radiation fan 71 is disposed. A flow path 84 is formed inside the radiator 70 ...

Abstract

The invention provides a composite absorption heat pump device capable of improving the recovery efficiency of engine exhaust heat by utilizing the absorption heat pump. In the absorption heat pump, exhaust heat recovery parts (20, 81, 21, 22, 23, 24) and cooling parts (25, 26, 71) are provided, and exhaust gas from the engine (72) is used in the exhaust heat recovery part To heat the mixture of absorption liquid and diluent produced in the absorber (6) of the absorption heat pump, thereby recovering the sensible heat of the exhaust gas, and condensing the water vapor contained in the exhaust gas to recover latent heat (heat of condensation) . Furthermore, in the cooling unit, condensed water formed by condensing water vapor is supplied to a cooler ( 7 ) for condensing the diluent in the absorption heat pump to be evaporated, thereby releasing latent heat (heat of vaporization).

Description

technical field [0001] The present invention relates to absorption heat pumps (absorption chillers). Background technique [0002] As a method of effectively utilizing heat (exhaust heat) generated by the engine, a technique of using exhaust gas flowing out of the engine for an absorption heat pump is known (for example, refer to Patent Document 1). In the technique described in Patent Document 1, sensible heat of exhaust gas is recovered as a heat source of an absorption heat pump. [0003] However, according to this technique, the exhaust heat recovery efficiency of the engine is still low, and a technique capable of improving the recovery efficiency of the engine exhaust heat is required. [0004] prior art literature [0005] patent documents [0006] Patent Document 1: JP-A-2009-262806 Contents of the invention [0007] The problem to be solved by the invention [0008] The present invention is made in view of the above-mentioned actual situation, and provid...
