Although water chillers can be divided into air-cooled and water-cooled chillers based on condenser cooling methods, there are also functional types of small water chillers. Different types of chillers are suitable for specific places and have different refrigerants.
Industrial small water chillers
Industrial Water Chiller is designed to cool water for manufacturing processes. Chilling water in the process can help to increase product quality and yield, reduce costs and improve the efficiency of manufacturing processes.
For example, an industrial water chiller is typically used in injection molding machines. Plastic injection molding refrigerators are known as molds. Their job is to cool the molds. Generally, they use the mold's cooling channels to circulate cold water through the molds to achieve a cooling effect.
Medical small water chillers
A medical refrigerating machine is a refrigerating machine designed to meet medical standards. The medical water chiller is designed for hospitals, clinics, and dental offices to cool down and maintain the ideal temperature of medical equipment such as MRI machines, CT machines, etc.
To be more specific, medical water chillers are used to prevent overheating of equipment during continuous operation, prolong the service life of equipment, ensure the reliability of equipment operation, and protect patient safety and data integrity.
Cooling capacity
The refrigerating capacity of water chillers is usually measured in watts or kilowatts, indicating the amount of heat they can absorb.
Compressor types
There are scroll compressors, centrifugal compressors and other types. Different compressors may have some differences in their cooling capacities and applicable environments.
Heat exchanger
The structure and working medium of heat exchangers may be different. Ice storage heat exchangers and evaporators are commonly used heat exchangers in water chillers. For example, water chillers with an evaporator also use refrigerants as heat exchange media.
Refrigerant
Water chillers use different refrigerants, such as R22, R410A, R134A, etc. Different refrigerants may have some differences in environmental protection and performance.
Power
Generally speaking, water chillers are mainly powered by electricity. The power is usually measured in kilowatts (KW), which indicates the power consumption of the equipment.
Regular maintenance can keep water chillers in good working condition and improve their lifespan and efficiency.
Regular inspection
It is necessary to check the appearance of small water chillers regularly, ensuring there are no loose parts, deformations, or damages. Meanwhile, users also need to inspect the refrigerant and check whether the amount is sufficient and whether there is any leakage. Besides, electrical components and circuits also need to be checked to avoid possible safety hazards.
Clean maintenance
Users should clean the condenser and evaporator of the small water chiller regularly. Dust and debris on these components can be removed by vacuuming or brushing them gently. Also, ensure proper water drainage and cleaning of the water tanks and pipelines. This practice can help prevent bacteria and algae growth.
Lubrication
The compressors and pumps of small water chillers are their vital components. Therefore, ensuring proper lubrication of these components is indispensable. Users can apply lubricating oil to moving parts to reduce friction and wear.
Pay attention to temperature and pressure
Users need to pay attention to the temperature and pressure indications of small water chillers, ensuring they are operating within the normal range. If there are any abnormal conditions, such as changes in temperature and pressure exceeding the prescribed limits, they should find out the reasons and deal with them in time.
Thanks to their compact design and excellent performance, small water chillers can be used in many scenarios.
Food processing industry
Small water chillers are extensively used to cool and preserve perishable foods such as meat, dairy products, and fresh produce. They help maintain optimal temperatures during processing, packaging, and storage to extend shelf life and prevent spoilage.
Soft drink production
In beverage manufacturing facilities, small water chillers are used to cool carbonated drinks, juices, and dairy beverages. They ensure that drinks are produced and stored at the right temperatures to maintain quality and prevent fermentation or spoilage.
Medical and pharmaceutical industry
Small water chillers are used to cool medications, especially temperature-sensitive ones such as vaccines, antibiotics, and biological products. They also play a crucial role in cooling laboratory equipment like centrifuges, incubators, and refrigerators.
Hospital and healthcare facilities
Hospitals and healthcare facilities use small water chillers to cool medical equipment, maintain optimal temperatures in operating rooms, and support HVAC (Heating, Ventilation, and Air Conditioning) systems. This ensures the proper functioning of critical healthcare systems.
Hotels and restaurants
Small water chillers are used in the hospitality industry to cool beverages, maintain refrigeration systems, and support HVAC systems for climate control in guest rooms and common areas.
Agriculture and horticulture
Small water chillers can be used in agricultural applications to cool irrigation systems, especially in high-temperature environments. They can also be used in greenhouses to maintain optimal temperatures for plant growth and development.
Food production, medical services, manufacturing, and several other industries require small chillers for cooling processes. One of the ways retail buyers can source small water chillers is by scouting selected categories on Alibaba.com. Even after choosing a seller, buyers must be careful to select the right chillers for their customers.
Understanding applications
Retail buyers should start by understanding the applications of the water chiller. This guides them in selecting a type with the right cooling capacity. Generally, different settings require different chilling capacities. If a buyer settles for a chilling capacity that is too high or too low for its application, it may affect the performance of the chiller and the processes of the application.
Considering preferred brands
Apart from the chilling capacity, application, and preferred brands, buyers must consider the features of the water chiller. These features will distinguish one brand from another. Some useful features to discover are temperature control, noiseless operation, energy efficiency, and fault detection capabilities, among others. Each suggested feature has its unique benefits. By choosing a chiller with some of these useful features, retail buyers can discover lucrative selling points.
Checking warranty
The small water chiller has complex internal mechanics. Retail buyers should double-check the warranty period of the chiller before purchase. This will ensure that they can receive product repair and replacement support for a reasonable period.
Q: How big is a small water chiller?
A: AHRI Standard 550/590 defines chillers in a manner that differentiates them by size and scope. According to this definition, small chillers are typically less than or equal to 150 cooling tons in capacity. Generally, small chillers can fit in building systems or exterior spaces, and some can be installed on rooftops.
Q: Does a water chiller use a lot of electricity?
A: The average water chiller's energy use is typically between 10 to 40 kWh per hour.
Q: Where are small water chillers used?
A: Small water chillers are used in many places, such as commercial buildings, industrial facilities, equipment cooling, medical facilities, laboratories, and food and beverage processing.
Q: How does a small water chiller work?
A: A small water chiller removes heat through the evaporation of water. It uses a refrigerant to absorb heat from the liquid (usually water) that needs to be chilled. During this process, the refrigerant evaporates and transforms into a gas. Then, the gas is compressed by the compressor into a high-pressure gas. Next, the high-pressure gas is condensed into a high-pressure liquid in the condenser by releasing the absorbed heat. Finally, the high-pressure liquid flows through an expansion valve or valve system, where it rapidly expands, reducing its pressure and temperature. Then, the cycle starts again.
