Working Principle Of Evaporative Condenser

Working principle of evaporative condenser

The working principle of the evaporative condenser is to send the high-temperature steam that needs to be condensed into the coil from the upper inlet of the heat exchange coil. The high-temperature steam releases heat in the heat exchange coil, and after being cooled, it undergoes a phase change and condenses into a liquid. Circulating spray water is used as the cooling medium outside the heat exchange coil, so that the water is evenly sprayed on the outer surface of the heat exchange coil to form a uniform and moderate water film. The water film absorbs the heat released by the hot steam in the coil and evaporates. , and then the water vapor is taken out of the evaporative condenser by the fan to take away the heat in the coil. The evaporative condenser utilizes the latent heat of evaporation of spray water, uses the ambient air as the medium, and uses the ambient wet bulb temperature as the temperature difference to perform heat exchange. It has the advantages of low condensation temperature, large heat transfer temperature difference, sufficient heat exchange, low power consumption, and stable performance. advantage.

The composition of the evaporator

The evaporator of the ice machine rotates slowly counterclockwise under the drive of the reducer, including the ice blade, sprinkler tray, main shaft, and water receiving tray. Water enters the water distribution tray from the water inlet of the ice machine evaporator, and through the sprinkler pipe, the water is evenly sprinkled on the icing surface to form a water film; the water film exchanges heat with the refrigerant in the refrigerant flow channel, and the temperature drops rapidly , A thin layer of ice is formed on the icing surface, and under the extrusion of the skates, it breaks into flakes of ice and falls into the ice storage from the ice outlet. Part of the unfrozen water returns to the cold water tank from the water return port through the water receiving tray, and circulates through the cold water circulation pump.

Flake ice machines have been widely used in aquatic products, food, supermarkets, dairy products, medicine, chemistry, vegetable preservation and transportation, marine fishing and other industries. With the development of society and the continuous improvement of people's production levels, the industries using ice are becoming more and more extensive. The quality requirements for ice are getting higher and higher. The requirements for "high performance", "low failure rate" and "hygiene" of ice machines are becoming more and more urgent.
