      Integrated solar energy small absorption refrigeration unit

      Solar air conditioning is driven by clean solar energy. the system meet the requirements of environmental protection. It not only saves power and fuel, energy conservation and environmental protection, but also almost zero emission. It is fully meet the requirements of sustainable development strategy.

      Another advantage of solar air conditioning is: the application of solar air conditioning coincides with the season. The higher the temperature in summer, the more cooling capacity people need. At this time, the stronger the sunlight radiation, the greater the output energy of solar energy and the cooling capacity provided by solar air conditioning also reaches a large value. Solar energy is inexhaustible. Solar air conditioning can save more than 90% electricity

      The unit integrates absorption chiller, cold water pump, cooling water pump, hot water pump, valve and filter, which is convenient for users to install.

      working principle

      Lithium bromide-water absorption refrigeration device is mainly composed of four parts: generator, condenser, evaporator and absorber. Its basic working principle is as follows:

      (1) Use the working heat source (such as water vapor, hot water and gas, etc.) to heat the dilute solution delivered from the absorber by the solution pump in the generator, and evaporate the water in the solution.

      (2) Water vapor enters the condenser, and is condensed into refrigerant water by the cooling medium.

      (3) The refrigerant water enters the evaporator through throttling, absorbs the heat in the refrigerant water and is excited into water vapor.

      (4) The concentrated solution remaining after the occurrence process in the generator enters the absorber, mixes with the water vapor from the evaporator, absorbs the water vapor and returns to its original concentration, becoming a dilute solution. The dilute solution enters the generator through the solution pump and continues to circulate.

      Product advantages

      1、The unit uses waste heat and waste heat for refrigeration,almost no energy is needed.Operation cost is very low;

      2、Each chamber inside the unit is designed with vacuum insulation layer to reduce internal heat loss and improve unit efficiency;
