THREE-STAGE TEMPERATURE RISING TYPE ABSORPTION HEAT PUMP

摘要

PROBLEM TO BE SOLVED: To provide a three-stage temperature rising type absorption heat pump device which reduces a height dimension of the device and improves a start-up property especially, the temperature rising type absorption heat pump device being adapted to generate vapor or the like at a higher temperature than a heat source temperature while using low-quality heat such as hot water as a heat source.SOLUTION: In a solution flow, a can body housing a low-temperature absorber and a low-temperature evaporator is disposed on a can body housing a condenser and a regenerator or horizontally at the substantially equal height. A can body housing a high-temperature absorber and a can body housing a medium-temperature absorber are disposed at the substantially equal height higher than the can body housing the low-temperature absorber and the low-temperature evaporator. The solution flow is adapted to introduce with a solution pump a solution which is condensed by the regenerator, to the high-temperature absorber and the medium-temperature absorber in parallel.
