Main characteristics of fully automatic water-cooled screw type (dual head) chiller unit 2025-07-11 Main characteristics of fully automatic water-cooled screw type (dual head) chiller unitAccurate control of microcomputer temperature. The Dongxing brand water-cooled screw chiller microcomputer controller adopts a large Dong Mu dot matrix wave crystal display, with a good Chinese human-machine dialogue interface to achieve full function automation control. The LCD screen displays the machine's working status in a timely manner and monitors the operation of the unit in a better state. Its touch panel seal is excellent, waterproof, dustproof, corrosion-resistant, and the button life is long. Infinite and graded energy controlThe Dongxing brand water-cooled screw chiller is used in general industrial refrigeration systems and is equipped with energy grading control systems of 75%, 50%, and 25%. This ensures that the unit can achieve greater energy-saving effects at partial loads. However, if water temperature control is required, it can be customized according to user requirements. All models can be equipped with stepless energy control,2, High operational efficiencyThe heat exchanger of the Dongxing brand water-cooled screw chiller adopts high-efficiency corrugated tubes and an efficient screw compressor, ensuring the high-efficiency operation of the unitThe most reliable protection and auxiliary componentsDongxing brand water-cooled screw chillers are equipped with safety protection devices to prevent any operational failures; Compressor protection design includes overcurrent relay, compressor motor temperature sensor, antifreeze temperature controller, sight glass, oil heater, compressor reverse phase protection relay, high and low voltage protection, exhaust high temperature protection, safety, and easy to dissolve plugs
Specific operating steps of the cooling water tower of the freezer 2025-07-11 The working process of the cooling water tower for industrial refrigerators is as follows:1. The hot water autonomous room is a water pump that uses a certain pressure to circulate water through pipes, horizontal pipes, curved pipes, and central pipes into the water distribution system of the cooling tower; 2. Purification workbench, evenly sprinkle water on the filling material through the small holes on the sprinkler pipe;3. Dry low humidity air enters the tower from the bottom under the action of the fan, and the net enters the tower. When hot water flows through the surface of the packing, it forms an air and water film for heat exchange. High humidity hot air is extracted from the top, and the cooling water drops into the chassis and flows into the main engine through the outlet pipe.4. When the fan is running, under the action of static pressure inside the tower, water molecules continuously evaporate into the air, becoming water vapor molecules. The average kinetic energy of the remaining water molecules will decrease, thereby causingThe temperature of the circulating water decreases; 5. Evaporation cooling is not related to the temperature of the air being lower or higher than the water temperature. As long as water molecules can continuously evaporate into the air, the water temperature will decrease. When the air in contact with water is not saturated, water molecules continuously evaporate into the air. However, when the air on the water vapor contact surface reaches saturation, water molecules cannot evaporate and are in a state of dynamic equilibrium; 6. The number of water molecules evaporated is equal to the number of water molecules returned from the air to the water, and the water temperature remains constant. From this, it can be seen that the drier the air in contact with water, the easier it is to evaporate in a low-temperature constant temperature bath, and the lower the water temperature.In short, while analyzing the specific operating procedures of the cooling tower of the freezer, we should always pay attention to its problems, constantly innovate and strive for better development.
