Problems solved by technology

When the temperature difference between the waste heat resource and the cooling medium is large, the heat recovery is used at this time, and there is also a large temperature difference between the waste heat medium and the cooling medium that completes the heat recovery process; in this way, the high temperature waste heat load is only performed once In the heat recovery process, there will be a situation where the temperature difference cannot be fully utilized

Abstract

The invention provides a double-effect back-heating absorbing-generating system and a back-heating second-class absorption heat pump, belonging to the technical field of heat pumps. The double-effect back-heating absorbing-generating system consists of a first generator, a second generator, a first absorber, a second absorber, a third absorber, a steam distribution chamber, a solution throttling valve, a plurality of solution pumps and a plurality of solution heat exchanger. The first generator provides refrigerant steam to a condenser, the second generator provides the refrigerant steam to the third absorber, the steam distribution chamber provides the refrigerant steam to the second absorber, an evaporator provides the refrigerant steam to the first absorber, the condenser provides liquid refrigerant to the evaporator through a liquid refrigerant pump, the first absorber supplies heat to the external world, and the condenser, the second absorber or / and the third absorber complete cooling and heat release to form the back-heating second-class absorption heat pump with a double-effect back-heating flow.

Description

Technical field: [0001] The invention belongs to the technical field of low-temperature waste heat utilization heat pumps. Background technique: [0002] In the process of the second type of absorption heat pump, heat recovery is an effective method to increase the heating temperature of the heat pump; at the same time, the use of heat recovery can also make the second type of absorption heat pump have adjustable heating parameters, continuous and adaptive performance index Advantages of variable operating conditions. When the temperature difference between the waste heat resource and the cooling medium is large, the heat recovery is used at this time, and there is also a large temperature difference between the waste heat medium and the cooling medium that completes the heat recovery process; in this way, the high temperature waste heat load is only performed once In the reheating process, there will be a situation where the temperature difference cannot be fully utilized....
