the circulating water cooling equipment such as water coolers (air-cooled water coolers and water-cooled water coolers), low-temperature freezers, screw water chillers, circular coolers, coolers, mold warmers, glass fiber reinforced plastic cooling towers, and pipeline pumps. Widely used in: plastic machinery, beverage machinery, rubber plastics, sound waves, chemical biology, medical care, food, electronics and other related industries.
Brief introduction of water chillers:
Industrial water chillers are widely used in plastics, electronics manufacturing, electroplating, medicine and chemical industry, ultrasonic cooling, printing and other industrial production. It precisely controls the temperature required by modern industrial mechanized production, thus greatly improving production efficiency and product quality. Industrial chillers are simple to operate, reasonable in design and excellent in quality. There are hundreds of specifications, and they are indispensable companions for modern industrial production.
characteristics of water chillers
1. The units are selected from imported famous brand compressors, with built-in safety protection, low noise, electricity saving and durability.
2, imported water pump, large flow, high efficiency, durable.
3. It is equipped with imported precision digital temperature controller, which can accurately control the water temperature by 1℃ and set the temperature range from 5℃ to 5℃.
4. All-stainless steel thick water tank, coil evaporator, built-in water supply device, etc. are convenient for cleaning and maintenance.
5. The condenser of the water-cooling unit is shell-and-tube type, with copper tube with internal thread, which has reasonable design and good heat exchange effect.
6. The appearance of the unit is beautiful and generous, and the outer panel is in the form of quick disassembly, which is convenient for use and maintenance.
operatiON flow of the water cooler:
1. first, turn the power supply on.
2. Turn on the cooling switch. At this time, please note that the cooling water inlet and outlet valves must be opened; (Air-cooled without water tower).
3. Turn on the switch of the chilled water pump again. Be careful that the valves at the inlet and outlet of chilled water must be opened, and the machine will run automatically after being compressed by the delay switch. Please check and adjust the required temperature.
4. when turning off the machine, please turn it off in the reverse order.
Matters needing attention in the operation of water chillers
1. The chilled water pump should not run without water in the water tank;
2. Please avoid continuous switching when operating the switch;
3. When the freezing water temperature reaches the set temperature, the compressor will automatically stop running, which is a normal phenomenon;
4. Avoid setting the temperature switch below 5℃ to prevent the evaporator from freezing; (except cryogenic refrigerator).
5. in order to ensure the refrigeration effect of the chiller and keep it in the best condition, please clean the condenser, evaporator and water filter regularly.
composition of water chillers:
the water chillers are mainly composed of fully enclosed compressors, condensers, thermal expansion valves, drying filters, evaporators, gas-liquid separators and protective devices.
working principle of water chiller
during refrigeration, the refrigeration compressor sucks the low-pressure and low-temperature refrigerant gas (R22) in the water-heat exchanger into the cylinder, and after the compressor does work, it becomes a gas with high pressure and temperature, which enters the condenser. The high-temperature and high-pressure refrigerant gas exchanges heat with the cooling medium water to transfer heat to the water, and the refrigerant gas condenses into a high-pressure liquid. The high-pressure liquid enters the evaporator after throttling and depressurizing. In the steamer, the low-pressure liquid refrigerant vaporizes and absorbs the heat of the surrounding medium (refrigerant water), so that the refrigerant water is cooled down and becomes the required low-temperature water. The vaporized low-temperature refrigerant gas in the water-heat exchanger is sucked and compressed by the compressor, so that it is circulated repeatedly and cold water is continuously produced.
I hope I can solve the problem for you!
