process
Solar adsorption refrigeration 1. Desorption process. The adsorption bed is full of Adsorbent The refrigerant is adsorbed, and the condenser is connected to the cooling system. Generally, the cooling medium is water. When working, the solar collector heats the adsorbent bed, the refrigerant gets energy to overcome the attraction of the adsorbent and desorbs from the adsorbent surface, enters the right pipe, and the system pressure increases. When the pressure is equal to the saturation pressure at the corresponding temperature in the condenser, the refrigerant begins to liquefy and condense, and finally the refrigerant condenses in the condenser, and the desorption process ends. In this process, the solar collector provides energy and the condenser releases heat. 2. Adsorption process. The cooling system cools the adsorption bed, the temperature drops, the adsorbent begins to absorb refrigerant, and the pressure in the pipeline decreases. The refrigerant in the evaporator evaporates and absorbs heat due to the instantaneous pressure drop to achieve the refrigeration effect. The refrigerant reaches the adsorption bed and the adsorption process ends. In this process, the evaporator absorbs the heat of refrigerant water and the adsorption bed releases heat.
For solar adsorption collectors, either flat plate collectors or Vacuum tube collector 。 Through the design of buried pipes in the solar adsorption collector, auxiliary energy can be used to heat the adsorption bed, so that the refrigeration system can work under reasonable conditions; In addition, if cooling water is passed through the buried pipe of the solar adsorption collector to recover the sensible heat and adsorption heat of the adsorption bed, so as to improve the adsorption effect, it can also provide domestic hot water for families or users. Of course, since the adsorption bed is generally a vacuum system or a pressure system (depending on the adsorbent refrigerant material), good sealing is required. In addition to meeting the evaporation function of general evaporators, the evaporative liquid receiver also requires a certain liquid storage function, which can be achieved by using conventional tube shell evaporators and increasing the shell volume.
