Energy tower refrigerant regeneration system based on air energy recovery

Abstract

The invention discloses an energy tower refrigerant regeneration system based on air energy recovery. The energy tower refrigerant regeneration system comprises a sedimentation tank, a preheating assembly, a boiling evaporation tank and an electric heater, the output end of the sedimentation tank is fixedly connected with a first liquid guide pipe, and the end, away from the sedimentation tank, ofthe first liquid guide pipe penetrates through the preheating assembly and the boiling evaporation tank and is fixedly connected to the input end of the electric heater. According to the energy towerrefrigerant regeneration system, a dilute solution is separated into a concentrated solution and condensed water through boiling evaporation, then the dilute solution in the first liquid guide pipe is heated through the concentrated solution and the condensed water, so that the utilization rate of energy is increased, meanwhile the cycle utilization of the dilute solution is achieved, and the regeneration efficiency of the refrigerant is improved; and the energy tower refrigerant regeneration system is further provided with a preheating mechanism, the dilute solution in the first liquid guidepipe is heated through a second heat exchanger by means of heat of condensate water, then the dilute solution in the first liquid guide pipe is heated again through the second heat exchanger by meansof heat of the concentrated solution, the heat utilization rate is increased, and the energy consumption is reduced.

Description

Technical field[0001]The present invention relates to energy tower cooling media regeneration techniques, and is specifically a energy tower cooling media regeneration system based on air energy recovery.Background technique[0002]The energy tower heat pump is in the form of a new type of heat pump, and the crew design is flexible, operating energy efficiency, good adaptability and energy saving. When the energy tower refrigerant is running under low temperature and high humidity, the refrigerant will be in the air in the air, and the water steam in the air enters the refrigerant, affecting the normal operation of the heat pump system, most of the engineering to add solute to avoid Low-temperature antifreeze is thinner, which will not only cause waste of refrigerant, but also cause cold media to overflow from the tower. It can be seen that the regeneration process of low temperature and cold media is an important part of maintaining the normal and efficient operation of the system, a...

Problems solved by technology

However, there are certain problems in this regeneration method: on the one hand, the temperature of the concentrated refrigerant is relatively high, and it needs to use cooling equipment to lower its temperature before it can continue to be used in the normal operation of the energy tower heat pump system, wasting a lot of sensible heat

On the other hand, the regeneration process has humidity requirements for the air used for heat and mass exchange (usually directly using outdoor air). If the air humidity is high, the regeneration efficiency will be greatly reduced
