Benefits of technology
The invention is a special type of heat pump that can provide multiple-terminal heating and meet the needs of large temperature differences. It has good thermodynamic efficiency, which helps improve the use of waste heat.
Problems solved by technology
In the field of adopting the first-type absorption heat pump to use waste heat, there are some limitations by adopting two heating ports associated with the absorber and condenser to complete absorption heat pump heating process when the heated medium temperature change range is wider relatively.
The low temperature heating segment and high temperature heating segment of the heated medium can't be satisfied by adopting a reasonable temperature difference at the same time.
And the absorption heat pump process with high performance index can't be used now.

The invention provides the first-type absorption heat pump with multi-terminal heat supply which belongs to the area of low-temperature waste heat utilization and refrigeration technique. It mainly comprises a generator, the first absorber, the second absorber, an absorption-evaporator, a condenser, a evaporator, a throttle, a solution pump or the second throttle, the first solution pump, the second solution pump, the first solution heat exchanger and the second solution heat exchanger. The second absorber provides solution for generator. The generator provides solution for the first absorber. The first absorber provides solution for the absorption-evaporator. The absorption-evaporator provides solution for the second absorber. The generator provides the refrigerant vapor for condenser. The condenser provides the refrigerant liquid for evaporator. The evaporator provides respectively the refrigerant vapor for the first absorber and the absorption-evaporator. The evaporator provides the refrigerant liquid for the absorption-evaporator and then absorbs heat and becomes refrigerant vapor providing for the second absorber. The first absorber, the condenser and the second absorber provide heat. The first-type absorption heat pump with multi-terminal heat supply is thereby formed.
Description
FIELD[0001]The present invention belongs to the area of low-temperature waste heat utilization and refrigeration technique.BACKGROUND[0002]In the field of adopting the first-type absorption heat pump to use waste heat, there are some limitations by adopting two heating ports associated with the absorber and condenser to complete absorption heat pump heating process when the heated medium temperature change range is wider relatively. The detailed performance is as follows. The heating temperature of the absorber and condenser associated is similar in a process of the absorption heat pump. The low temperature heating segment and high temperature heating segment of the heated medium can't be satisfied by adopting a reasonable temperature difference at the same time. Or the heating temperature difference of low temperature segment is larger relatively when the low temperature heating segment and high temperature heating segment of the heated medium is satisfied at the same time. The uti...
