Title:
Absorption chiller / heater
Document Type and Number:
Japanese Patent JP6364238
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a waste heat recovery type absorption water chiller/heater capable of effectively utilizing two kinds of different hot water hater sources.SOLUTION: An absorption type water chiller/heater including an evaporator for storing refrigerant liquid, an absorber for storing a diluted solution absorbing vapor of the refrigerant, a condenser for condensing the vapor of the refrigerator, a high-temperature regenerator heating the diluted solution to evaporate the refrigerant to obtain a concentrated solution, a low-temperature regenerator heating the diluted solution at a temperature lower than the high-temperature regenerator to evaporate the refrigerant and to obtain a concentrated solution, and a liquid-liquid heat exchanger for heating the diluted solution, is constituted to supply two kinds of hot water heat sources of a first hot water heat source and a second hot water heat source. A part of the diluted solution is heated by the first how water heat source in the liquid-liquid heat exchanger, and then heated by the high-temperature regenerator to be the concentrated solution, the other part of the diluted solution is heated by the first hot water heat source by the liquid-liquid heat exchanger, then heated by the vapor of the refrigerant generated in the high-temperature regenerator, and becoming the concentrated solution in the low-temperature regenerator, and a part of the diluted solution, the other part of the diluted solution, or all of the diluted solution is heated by the second hot water heat source.
