The temperature limit and working principle of ice making equipment

by:CBFI     2021-07-31
The condensing temperature limit of popular refrigeration equipment:    shall not be lower than 55℃, not lower than 20℃. In the Su-ri scenario, the use of water-cooled condensers is not recommended in areas where the wet bulb temperature exceeds 42°C. So whether you can choose a water-cooled condenser, it is important to confirm the wet bulb temperature of the scene. When imagining a water-cooled ice machine in general, it is necessary to ask the customer to provide the lowest wet bulb temperature in the inland year.  The evaporator of the flake Tube Ice Machine (EVEPORATOR)  The formation of the evaporator: The evaporator of the ice maker consists of ice skates, sprinkler tray, main shaft, and water receiving tray, which rotate slowly counterclockwise under the power of a reducer. The water enters the water diversion tray from the water inlet of the evaporator of the ice maker. After the sprinkler pipe, the water is evenly sprinkled on the icy surface to form a water film; the water film and the refrigerant flow in the refrigerant talk about heat exchange, The temperature dropped rapidly, forming a thick layer of ice on the icy surface. Under the squeeze of the ice skates, it broke into flakes of ice and was lost into the ice storage through the ice falling port. Part of the frozen water flows back into the cold water tank from the water return port through the process water tray, and is recycled by the process cold water circulating pump. Ice Maker-Domination Theory 1 The water used for ice making needs to be salted (in other words, dosing). As for the amount of water! Look at the amount of ice making and adjust the pump (plunger pump) actively.   2 The ice making equipment body is divided into two chambers. A copper tube with a certain density in the inner plate of the cavity in the body! The technical term is called (evaporation cavity), which is what is called refrigeration. The distance can be adjusted to 3 mm. There are several groups of copper nozzles spreading evenly on the upper circle of the ice skate! The water is evenly sprayed into the middle surface of the inner cavity and then the cooling surface of the middle cavity instantly forms a 3 mm thick ice surface. Under the impregnation of the rotating ice skates, the freshly made ice is broken into small pieces and dropped into the storage bin! Civil ice maker The basics are the same! That is, the inner cavity is a rotating ice box. The reasoning of the refrigerator is: 1. The chilled water pump in the water storage tank continuously circulates through the plate-type roughly divided evaporator; 2. The shrinking machine operation After inhalation-shrinkage-exhaust-condensation (liquefaction)-throttling-and then evaporate in the evaporator at a temperature of -10 to -18 degrees to absorb heat and vaporize. The chilled water is constantly changing at a water temperature of 0 degrees. The middle surface of the warm evaporator condenses into an ice layer. When the ice layer has condensed to a certain thickness, after the evaporation temperature of the refrigerant reaches the temperature control setting temperature, the defrost solenoid valve is turned on, and the heat pump is usually used for deicing. .
