Large ammonia chillers are widely used in the food production industry. Ammonia refrigerators generate a large amount of exhaust heat energy while cooling work. Traditionally, these exhaust heat energy is used as waste heat and discharged to the atmosphere through a condenser cooling fan. In this paper, the exhaust heat energy of ammonia refrigerator is analyzed. The exhaust energy is divided into two parts: sensible heat and latent heat. The sensible heat energy recovery and latent heat energy recovery and utilization schemes are studied respectively, and a aquatic product processing in Qingdao area is selected. The enterprise carried out the actual chiller heat recovery and recovery test. After three years of actual operation, the results show that the ammonia chiller exhaust heat energy and sensible heat recovery can obtain 40-70 degrees hot water for employee bathing and Production of sanitary cleaning, etc., and the cost of heat recovery is almost zero; the latent heat is partially recovered, the cooling water of the ammonia refrigerator is used as the water source, and the heat source is used to extract heat energy from the cooling water. The unit operates in winter, is not affected by the ambient temperature, and the heating efficiency is not Will decay, the energy efficiency ratio is maintained at more than 5 times.
