Different grade composite first kind absorption heat pump

Abstract

The invention provides a different-level compound first class absorption-typed heat pump and belongs to the technical field of waste heat utilization and heat pump / refrigeration. The invention aims atthe shortcoming of a single class heat pump and provides an integrated machine set consisting of a generator, a condenser, an absorber, an evaporator, an absorption-evaporation device, a throttle valve, a solution pump and other basic components; the invention is divided into three types respectively with a common evaporator, a common condenser or no common component; the processes of the heat pump in different levels are compounded through the evaporator or the condenser and / or waste heat medium channel simply while accompanied by other components; when sharing the evaporator, each condenser is interconnected through the throttle valve or is separated from each other or is separated partly; when under other conditions, waste heat medium enters into and comes out of each evaporator in sequence; refrigerant medium from the condenser enters into the evaporator and the absorption-evaporation device through the throttle valve and is absorbed by solution at each associated connection; diluted solution releases refrigerant into the condenser with the action of driven heat. The heat pump can take use of waste heat and refrigeration with waste heat has high benefit.

Description

Technical field: [0001] The invention belongs to the technical field of low-temperature waste heat utilization and heat pump / refrigeration. Background technique: [0002] Using absorption heat pump technology for waste heat utilization is an effective means, which has relatively good energy saving, environmental protection and economic benefits. In practical applications, the heat supply temperature and load of the heat pump should meet the heat demand of the user, and it should have a simple process and structure, as well as a performance index as high as possible. That is to say, the heat pump, an energy-saving device, should have comprehensive advantages such as low cost, simple and reliable operation, high performance index and good economic benefits. [0003] When the waste heat temperature is low or the heating temperature requirement is high, and the waste heat is not abundant enough, the first type of absorption heat pump technology is generally used to apply the wa...

Problems solved by technology

In this way, when the cooling requirements and the parameters of the driving heat are determined, the units using a single stage often cannot make full use of the driving heat to obtain more cooling capacity, especially when using waste heat for cooling—a unit with a single stage cannot Full and effective utilization of waste heat

Of course, using units of different stages to form a joint refrigeration system can achieve higher refrigeration efficiency, but the cost is also too high
