Abstract

The invention relates to a freeze dryer energy saving system utilizing solar absorption refrigeration and a running method thereof. The system is additionally provided with a heat storage unit composed of a defrosting water storage tank, an air-conditioning exhaust heat exchange mechanism and other components, the defrosting water storage tank is connected with a condenser and absorber of an absorption refrigeration unit through an air-conditioning exhaust heat recovery mechanism, the air-conditioning exhaust heat recovery mechanism is used for recovering exhaust heat of the condenser and absorber, the defrosting water storage tank is connected with a solar heat collection unit for heat and mass transfer, and a defrosting valve connected with the defrosting water storage tank can supply heated defrosting water to a cold trap for defrosting. Compared with the prior art, the freeze dryer energy saving system can absorb and store the exhaust heat of the absorption refrigeration unit and the excess heat of the solar energy, and is used in a defrosting system of a freeze dryer for defrosting.

Description

technical field [0001] The invention relates to the technical field of freeze dryers, in particular to an energy-saving system and operation method of freeze dryers utilizing solar energy absorption refrigeration. Background technique [0002] The technical feature of vacuum freeze-drying is to sublimate the moisture in the frozen items in a vacuum environment and finally dry the items, and the sublimated water is transferred to the cold trap coil to condense into ice again. This feature determines that the freeze dryer needs to use the heat medium circulation system to heat the material in order to sublimate the moisture of the item, and the ice desublimated on the cold trap coil must also need a lot of heat to melt and then be discharged. [0003] During the freeze-drying process of the freeze-drying machine, the cold trap needs to continuously capture the water vapor produced by sublimation, so the ice on the cold-trap coil will continue to freeze, and the ice captured by...
