The Yanfa condenser works by utilizing the principle that the cooling water absorbs heat when the water evaporates outside the heat exchange tube, causing the ammonia or fluorine vapor inside the tube to condense. The cooling water is stored in a bottom water tank and maintained at a certain water level with a floating ball. The cooling water is pumped by the circulating water pump to the top of the condensing coil, and flows through the nozzle to form a mist like water film, which is evenly covered on the outer surface of the condensing coil group. The temperature of the water film is low, and some of the water in the water film absorbs the heat of the high-temperature refrigerant vapor in the absorption tube, condensing it into liquid. The unevaporated water falls back into the collection tank of the condensing medical department. The air passes through the coils of the evaporative condenser under the action of the fan, taking away the evaporated water vapor. A water baffle is set up
