COOLING AND HEATING OPERATION METHOD BY ABSORPTION HEAT PUMP, AND ABSORPTION HEAT PUMP

摘要

PPROBLEM TO BE SOLVED: To further enhance cooling and heating efficiency in an absorption chiller and heater adopting a triple utility cycle. PSOLUTION: The absorption chiller and heater adopts the triple utility cycle having at least an absorber 81, an evaporator 89, a condenser 88, a low temperature regenerator 84, a medium temperature regenerator 87, a high temperature regenerator 10, a solution heat exchanger, a solution pump and a refrigerant pump. In the cooling and heating operation method by an absorption heat pump, triple utility cycle operation is performed in cooling operation, and waste heat recovery operation by the evaporator 89 in a double utility cycle is performed in heating operation to attain a performance coefficient of 1.4 or more in rated operation unattainable in the double utility cycle in both cooling operation and heating operation.
