True chiller

Types of true chillers

A true chiller, also known as a cooling machine, is a device that can lower the temperature of a substance. Generally, it is used in the refrigeration industry to cool and chill products. There are many types of chillers. They are usually categorized based on their application, cooling capacity, working principle, or structure.

• Application: Chillers are usually used in two areas, industrial and commercial. Industrial chillers are typically used for manufacturing processes and to provide temperature control for industrial equipment. On the other hand, commercial chillers are more suitable for air-conditioning systems and maintaining cold temperatures in commercial refrigeration facilities.
• Cooing capacity: Chilllers with different cooling capacities can meet various needs. Some small and medium-sized machines achieve a cooling result for domestic and small-scale use, while high-power machines focus on industrial-scale usage.
• Working principle: According to the working principle, chillers are generally divided into three types: absorption chillers, screw chillers, and thermally activated chillers. Absorption chillers use heat energy as power to absorb and cool heat through a refrigeration cycle. Screw chillers use twin-screw compressors to realize the refrigeration process. Thermally activated chillers are also known as absorption refrigerators. They use a chemical process called absorption to transfer heat from one place to another, utilizing a refrigerant and a heat source.
• Structure: According to the structure, chillers are usually divided into air-cooled and water-cooled types. Air-cooled chillers rely on ambient air to dissipate heat, while water-cooled machines use water as a heat exchange medium. Water-cooled chillers generally have a greater cooling capacity.

Specifications and maintenance of true chillers

Specifications

• Cooling capacity and refrigerant

  True chillers come with different cooling capacities measured in BTUs or kilowatts (kW). The chiller's capacity to absorb heat from the chilled liquid is indicated. It is essential to choose a chiller that will meet a specific application's cooling needs.

• Compressor

  A true chiller's compressor type and size can impact its performance, efficiency, and noise level. Selecting the right compressor for a specific cooling application and ensuring that it is properly sized to handle the intended load is essential.

• Condensing unit

  The true chiller’s condensing unit is selected based on factors such as the required cooling capacity, the type of refrigerant, the heat rejection method (air-cooled or water-cooled), and the installation environment.

• Evaporator

  A true evaporator works by absorbing heat from the liquid (usually water or a water-glycol mixture). As the heat is absorbed, the refrigerant inside the evaporator coils evaporates and cools down the liquid.

• Controls and sensors

  True chiller controls are the brain of the chiller system. They monitor and regulate various parameters, including temperature, pressure, and flow rates, to ensure optimal performance and energy efficiency. True sensors, on the other hand, are designed to detect and measure specific variables like temperature and pressure. They provide feedback to the chiller control system, allowing it to make adjustments as needed to maintain desired cooling rates and prevent potential issues.

Maintenance

• Inspection and cleaning of the condenser coil:

  The overall performance can be improved if the maintenance expert inspects and cleans the condensing coil of the true chiller regularly. The inspection should also include checking for proper airflow around the coil and eliminating debris within the vicinity.

• Lubricate moving parts:

  Regularly lubricating the moving components or parts of a true chiller helps enhance operating efficiency and mitigate the risks of premature equipment failure. This maintenance procedure helps prolong the lifespan of the true chiller.

• Monitoring temperature and pressure:

  Regularly monitoring the temperature and pressure of components of a true chiller, such as the evaporator and condenser, is essential for optimal performance. Maintenance technicians can identify any potential issues by closely monitoring these parameters, including abnormal fluctuations, deviations, or changes. Early detection allows for timely intervention, preventing possible breakdowns and ensuring the chiller operates at its best.

Scenarios of true chillers

The typical application of true refrigerators is to store food items such as fruits, vegetables, meat, dairy products, and beverages in a temperature-controlled environment. impel marketing true chillers also play an important role in hotels, restaurants, cafes, bars, and grocery stores where large amounts of food and drinks need to be kept at a constant cool temperature in order for them to be served fresh.

Laboratories and medical facilities use true chillers to store pharmaceutical products, reagents, and samples that must be kept at a specific temperature for them to maintain their effectiveness. Florists and event planners also use true chillers to maintain the freshness of cut flowers and other floral products as well as preserve valuable artifacts, artworks, and archival materials from being ruined by mold or mildew.

In the educational sector, true chillers are commonly used in universities and colleges especially in science laboratories where certain chemicals need to be refrigerated in order for them to function as required. In the industrial sector, true chillers are used in production and manufacturing processes such as material processing, electronics fabrication, and chemical production to maintain specific temperatures and control humidity.

How to Choose True Chillers

When looking for true chillers for sale, it is important to stock diverse types to meet different customers' needs. While most customers will look for commercial air conditioning chillers, there are different applications of true chillers that one can find and sell.

• Focus on Popular Types

  Typically, about 60% of the market demand is for air conditioning chillers, which are mainly used in commercial buildings. Consider stocking up on air conditioning chillers in different varieties to meet a broader customer base.

• Walk-Ins

  Walk-in coolers and chillers are other types of true chillers one may encounter when sourcing for refrigeration products. Many retailers will opt to stock walk-in chillers because they are almost a must for every commercial premise. Customers are not likely to concern themselves with the brand of the walk-in chiller as long as it serves the purpose effectively.

• Industrial True Chillers

  Industrial chillers are less popular but may still attract a specific customer base. Large manufacturers, factories, or processing plants are likely to require industrial true chillers. Focus on the large, trusted brands to reduce the risk of getting products that will not sell.

• True Chiller Tubes

  True chiller tubes are components of refrigeration systems. Many customers will buy these components to either replace a part of their existing refrigeration system or manufacture a complete system. True tubes are not costly, and if one is looking for a niche market, consider stocking true chiller tubes.

• True Chiller Cabinets

  Chiller cabinets are simple refrigeration systems that hold products and cool them. Companies that have not yet invested in large chillers, like commercial air conditioning chillers, may consider chiller cabinets. They can be a great option for restaurants, gyms, supermarkets, and other food businesses. Since the market is so vast, one could easily find their ideal customers.

FAQ

Q1: Are there any research trends surrounding chillers in recent years?

A1: According to many reports, the global industrial chiller market size was valued at around $9.6 billion in 2022 and is projected to reach approximately $17.2 billion by 2032, growing at a CAGR of 5.4% from 2023 to 2032.
