At present, the country to promote energy-saving emission reduction and the intensity of enterprise energy saving targets more stringent.Design and improvement of ammonia absorption refrigeration system evaporator can further increase the utilization of waste heat, improve the peoples production and living environment. This design mainly to simulate industrial waste heat absorption evaporator design, concrete data is given priority to with practical investigation, such as industrial waste water, waste gas temperature of roughly 105 degrees Celsius. Industrial application basic plate type evaporator for three-way or four-way, this design USES two effect. The literature and information understanding type evaporator and the advantages a
