Air Cooled Chillers

Choosing a chiller that suits your needs requires considering multiple factors. Here are some suggestions for purchasing a chiller:   1. Determine the cooling capacity of the chiller Determine the cooling capacity of the required chiller based on actual needs. For example, factories, hospitals, etc. have high requirements for cooling capacity and need to choose chillers with larger cooling capacity, such as 200kw chillers, 500kw chillers, 1000kw chillers, 1500kw chillers, etc.; while some small injection molding equipment need to choose chillers with smaller cooling capacity. Such as 5ton chillers, 8ton chillers, 10ton chillers, etc. If you don’t know or are not sure how big an industrial chiller to buy, you can tell the application industry, equipment flow, inlet and outlet water temperature, ambient temperature, refrigerant type, voltage and other special requirements, such as pump flow, pressure requirements, explosion-proof requirements, etc. Hengde Company will recommend an industrial chiller that suits your company’s needs based on all your requirements.   2.Consider the brand and after-sales service of the chiller  The quality and after-sales service of well-known brands of chillers are better, which can ensure the long-term and stable operation of the equipment. At the same time, you should also understand the warranty period and maintenance policy of the chiller. Hengde Company has more than 15 years of experience in the chiller industry, passed ISO9001, CE, SGS and other certificates, and obtained 8 patent certificates. At the same time, Hengde Company has a complete pre-sales and after-sales system, providing 24-hour customer service. Free pre-sales consultation, technical and operation training, and on-site guidance on the installation and commissioning of the chiller according to the actual needs of customers, so that you have no worries.   3.Consider the installation conditions of the chiller According to the place of use and environment, choose suitable chiller installation conditions, such as power supply, water source, ventilation conditions, etc. For some places with limited space or inconvenient water source, you can choose air-cooled chillers, which are easy to install and occupy a small area. For places with sufficient water source and high cooling requirements, you can choose water-cooled chillers, which generate relatively less noise during operation.   4.Consider the price of the chiller When purchasing a chiller, price is an important consideration. You need to choose a cost-effective device based on your budget and actual needs. But price is not the only factor. The cost-effectiveness of the chiller needs to be comprehensively evaluated based on product quality, technical support and after-sales service.   5. Safety performance and maintenance convenience Check whether the chiller has complete safety protection measures, such as high and low voltage protection, overload protection, leakage protection, etc. High and low voltage protection can prevent the compressor from being damaged under abnormal pressure, overload protection can prevent the motor from burning due to long-term overload, and leakage protection ensures the safety of the operator. Choose a chiller that is easy to maintain. For example, the structural design of the equipment should be easy to disassemble and overhaul, and key components (such as compressors, water pumps, etc.) should be easily accessible. At the same time, the manufacturer should provide detailed maintenance manuals and technical support to facilitate users to perform daily maintenance and troubleshooting.   In short, when purchasing an industrial chiller, you need to consider the above factors comprehensively according to your actual needs and situation and choose the equipment that suits you. At the same time, pay attention to the maintenance and care of the equipment to ensure its long-term stable operation.   Choose Hengde, Choose Perfect Industrial Chillers!

Chillers achieve cooling primarily through the refrigeration cycle, where four key components—compressor, condenser, expansion valve, and evaporator—work in close coordination. Below is a detailed explanation of how chillers create an effective cooling process:   1.Compressor Pressurization The compressor, as the heart of the chiller, plays a crucial role in converting low-temperature, low-pressure refrigerant gas into high-temperature, high-pressure gas. During the compression process, the temperature and pressure of the refrigerant gas both rise. This change in state sets the stage for the subsequent condensation process, as refrigerant gas at higher pressures is more effective at transferring heat to the cooling medium, leading to a phase change.   2.Condenser Heat Exchange Once the high-temperature, high-pressure refrigerant gas enters the condenser, it undergoes heat exchange with the surrounding environment. In air cooled chillers, a fan drives air through the condenser to carry away heat, while water-cooled chillers utilize circulating water to absorb heat. During this process, the refrigerant gas cools down and condenses into a high-pressure liquid. Condensers are typically equipped with high-efficiency heat dissipation devices, such as variable-speed fans or enhanced heat exchange tubes, to improve heat transfer efficiency and speed up the refrigerant condensation process.   3.Expansion Valve Throttling and Pressure Drop When the high-pressure liquid passes through the expansion valve, there is a significant drop in both pressure and temperature. The primary function of the expansion valve is to regulate the flow of refrigerant, ensuring that it can fully evaporate in the evaporator, thereby achieving an effective cooling effect. This flow control is critical for maintaining the stable operation of the refrigeration system and optimizing its cooling efficiency.   4.Evaporator Heat Absorption The low-pressure, low-temperature refrigerant liquid enters the evaporator, where it quickly absorbs heat from the surrounding environment. In practical applications, chillers primarily absorb heat from cooling water, causing the refrigerant to vaporize into a low-temperature, low-pressure gas. During this process, the water inside the evaporator is cooled and then pumped to the equipment or systems that need cooling, transferring the heat and meeting the cooling demands of the system.   Through the continuous cycle of these four steps, chillers can reliably supply low-temperature cooling water to equipment or systems, ensuring stable operation under optimal temperature conditions. Compressor: Increases refrigerant pressure and temperature. Condenser: Dissipates heat, causing refrigerant to liquefy. Expansion Valve: Reduces refrigerant pressure. Evaporator: Absorbs heat, achieving cooling.   In summary, industrial chillers rely on the seamless cooperation of the compressor, condenser, expansion valve, and evaporator, as well as the continuous flow of refrigerant through these components, to achieve cooling. This process ensures the circulation of cooled water for various industrial applications and research experiments, providing reliable cooling support.    Hengde, with years of expertise in the chiller industry, is committed to continually optimizing product performance.
