Because chillers play an important role in industrial production, chillers are required in the refrigeration process of various industries such as electroplating, chemical industry, printing, pharmaceuticals, and plastics. At the same time, the assets account for a large proportion. Industry friends should deal with the chiller system Have a general understanding.
Since the chiller has a wide range of applications, we need to understand the three circulation systems of the chiller. Below, the editor of Kaydeli Chiller will guide industry friends to understand the three major system principles of the chiller.
Chillers are not only suitable for plastic products, electronic and electrical industries, but also for medical equipment, leather processing and other industries, as well as air conditioning and refrigeration in people's daily life. Chillers are interconnected to operate through three systems:
Refrigeration, circulation system, electrical, electrical automatic control system.
1. Refrigerant circulation system.
After the refrigerant liquid absorbs the heat in the water in the refrigerant liquid phase in the evaporator of the industrial chiller, it begins to evaporate, and finally a temperature difference is generated between the water and the refrigerant, so that the liquid-phase refrigerator completely evaporates Become a gaseous state, after being absorbed by the compressor, the compressed gaseous refrigerant will cool down again through the condenser radiator, then the liquid phase, and finally complete the refrigeration cycle.
2. The water circulation system.
The function of the water pump is mainly to pump the water in the water to the equipment that needs to be cooled, and the water makes the heat rise, and then returns to the frozen water. Reminder: The water mentioned here refers to the tap water used in daily use, listed according to the situation of the water intake, if sea water or other water sources are used.
3. Electrical automatic control system.
Contains the automatic control part and power supply part of the industrial chiller system. The automatic control part includes relays, pressure gauges, temperature regulators, pressure regulators, temperature regulators, time regulators, load protectors and other components, and can automatically start or stop according to water temperature changes. The power supply part mainly supplies power to the compressor, water pump and power indicator light through the contactor.
The following are the two commonly used classifications of industrial chillers according to the heat dissipation method of the unit. When selecting models, they should be distinguished.
Water-cooled chiller: It should be confirmed that the working conditions of water-cooled industrial chillers require additional water cooling towers and water pumps for cooling and heat dissipation. In order to achieve a better cooling effect.
Air-cooled chiller: The heater is equipped with a heat-retaining heater and a water pump, and there is no need to add a cooling tower to the heater, so it is very convenient to install and move. But it requires more work environment. Since its cooling is carried out by air circulation, if the ventilation effect of the installation workshop is not good, it will directly affect the cooling effect of the chiller. In addition, if you want to install a chiller in a dust-free workshop with humidity requirements, then I suggest you choose water cooling equipment. Due to the air-cooled cooler, water vapor is sprayed on the top for cooling.
The next steps to consider are the main components of an industrial refrigeration unit:
The first is that the compressor is the heart of the chiller. We chose a new original chiller from Europe, America and Japan, with built-in safety protection, low noise, and energy saving.
The second is water tank cooking: thick stainless steel built-in automatic water replenishment device, which saves the tediousness of engineering installation, is easy to install and maintain, and is suitable for special occasions such as large and small flow.
The last is water-cooled condenser: large heat dissipation and small volume. It adopts the latest CAD/CAM design and production, cooperates with CNC machining center to complete the processing, with beautiful structure, high efficiency and energy saving.
The above is the introduction of the three major systems of industrial chillers, as well as several components that should be paid attention to when selecting chillers in the industry. I hope it will be helpful to friends in the industry.
