Abstract

The invention provides a double-effect regenerative absorption-generation system and a regenerative first class absorption heat pump, which belongs to the technical field of heat pumps. The double-effect regenerative absorption-generation system consists of a first generator, a second generator, a first absorber, a second absorber, a third absorber, a steam distributing chamber, a solution throttle valve, a plurality of solution pumps and a plurality of solution heat exchangers. Refrigerant steam is supplied to a condenser by the first generator, the refrigerant steam is supplied to the first absorber by the second generator, the refrigerant steam is supplied to the second absorber by the steam distributing chamber, the refrigerant steam is supplied to the third absorber by an evaporator, refrigerant liquid is supplied to the evaporator by the condenser through the throttle valve, and heat is supplied to outside by the condenser, the second absorber, the third absorber or/and the first absorber to form the regenerative first class absorption heat pump with a double-effect regenerative process.

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 first 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 first type of absorption heat pump have adjustable heating parameters and continuous change and adaptation of performance index Advantages of variable operating conditions. When the temperature of the waste heat resource is relatively low, the temperature drop of the driving heat medium is required to be large. At this time, when heat recovery is used, there will be a large temperature difference between the high-temperature driving heat medium and the heated medium to complete the heat recovery process; if the high-temperature drive heat The high-grade heat load of the medium only performs one reheating process, and...
