Chiller manufacturers analyze the classification of chillers
Many industrial productions cannot obtain high-efficiency industrial production without the low-temperature production environment provided by industrial chillers. Therefore, industrial chiller equipment is a very important professional refrigeration equipment in the industrial market. What is the classification of chillers in your eyes? At present, industrial water chiller products can be divided into different types, and their application range is relatively wide. So, what types of industrial water chiller products can be divided into? Let me introduce it to everyone below.
Air-cooled chiller: The air-cooled chiller mainly uses a cooling fan to dissipate heat from the aluminum platinum fin built-in cooler. The cooler generally adopts an axial flow upward blowing method. Its advantage depends on the simplicity of the equipment. It only needs to be connected to the cold water import and export trade. , Suitable for areas where tap water is inconvenient or lack of water sources. The air-cooled chiller is one of the chiller models. It cools the water at room temperature to a certain temperature through the compressor of the chiller to strengthen cooling of the mold or machine. It is used as a stand-alone machine. The heat sink is a built-in fan. There are three main mutual Linked systems: refrigerant circulation system, water circulation system, electrical automatic control system.
Electrical automatic control system: Including power supply part and automatic control part. The power supply part supplies power to the compressor, fan, water pump, etc. through the contactor. The automatic control part includes thermostat, pressure protection, time delay, relay, overload protection, etc. to achieve automatic start and stop according to the water temperature, protection and other functions.
Refrigerant circulation system: The liquid refrigerant in the evaporator absorbs the heat in the water and starts to evaporate. Eventually, a certain temperature difference is formed between the refrigerant and the water. The liquid refrigerant also completely evaporates into a gaseous state, which is then sucked in and compressed by the compressor (pressure and temperature increase) ), the gaseous refrigerant releases heat through the condenser and condenses into a liquid. After throttling through an expansion valve (or capillary tube), it becomes a low-temperature and low-pressure refrigerant and enters the evaporator to complete the refrigerant cycle process.
water circulatory system: The water pump is responsible for pumping the water from the water tank to the user's equipment that needs to be cooled. The chilled water will take away the heat and increase its temperature before returning to the chilled water tank.
Features of air-cooled chillers: Air-cooled chillers can be used in small systems, and most of the large units are water-cooled. The initial investment in water-cooling is a little less in terms of the main engine than air-cooled. But with the addition of cooling towers and electronic water treatment devices in the computer room, there is not much to go! Besides, in terms of long-term operation, the cooling efficiency of water-cooled units Relatively will drop, air cooling will not. The air-cooled chiller adopts the air cooling method, eliminating the need for cooling towers, cooling water pumps and piping systems that are essential for the cooling water system, avoiding condenser fouling and water pipe blockage in areas with poor water quality, and also saving water resources. Among the current cold water air-conditioning equipment products, maintenance and repair are the most economical and simple models.
Water-cooled chiller: The water-cooled chiller mainly uses water to dissipate heat from the shell and tube cooler. It needs to be retrofitted with a closed cooling tower. It is opposite to the air-cooled chiller. The water-cooled chiller does not require a cooling fan and is superior in energy consumption. The cold water chiller, and it is through the water to carry out the heat pipe heat dissipation, the heat exchange efficiency is higher than the air-cooled water chiller.
Features of water-cooled chillers: 1. Easy to install, easy to operate, suitable for cooling of various factory equipment. 2. Low noise water pump, compressor motor, excellent cooling and condensation effect, stable throttling mechanism, and excellent anti-rust treatment. 3. Adopt high-performance compressor imported from Europe and America, high EER value, low noise, stable operation 4. Ergonomic panel, fully automatic control, equipped with precision electric temperature controller, can run smoothly for a long time. 5. The use of high-efficiency heat transfer heat exchanger has the advantages of less cold loss, easy oil return, and no freezing and cracking of the heat transfer tube. 6. Adopt high-performance compressor imported from Japan and the United States, with high EER value, low noise and stable operation. 7. The structure is highly optimized, the heat exchanger plate is used to support the body, the structure is simple, compact and practical. 8. The perfect combination of branded compressors and the highest quality gao school energy heat exchanger, with an energy efficiency ratio of up to 5.5. 9. Multi-stage or stepless capacity control to accurately coordinate with load changes.
