their strong cooling capabilities and flexible installation methods, making them the preferred temperature regulation solution for large 

areas such as factories and workshops. This article will comprehensively analyze industrial vertical air conditioners with a cooling capacity 

ranging from 7.5kW to 50kW. Starting from their basic definitions and working principles, it will thoroughly analyze performance parameters 

and features, objectively evaluate advantages and disadvantages, explore typical application scenarios, and provide a specific application 

case of an automotive manufacturing workshop. Finally, it will look forward to future development trends, providing comprehensive selection 

and application references for industrial users. 

Overview and Working Principle of Industrial Vertical Air Conditioners

Industrial vertical air conditioners are large-scale refrigeration devices specifically designed for industrial environments. They are usually 

installed in a floor-standing manner and come in either integrated or split structures. Compared to household or commercial air conditioners, 

industrial vertical air conditioners have significantly improved in terms of cooling capacity, operational stability, environmental adaptability, 

and service life, enabling them to meet the strict temperature control requirements of industrial production. These air conditioners have 

a wide range of cooling capacities, from small units of 7.5kW to large systems of 50kW, capable of meeting the needs of different-sized 

industrial spaces. 

From a structural perspective, industrial vertical air conditioners are mainly composed of core components such as compressors, condensers, 

evaporators, expansion valves, and control systems. Their working principle is similar to that of traditional air conditioners, based on the 

refrigeration cycle principle: refrigerant is compressed into a high-temperature and high-pressure gas in the compressor, flows through 

the condenser to dissipate heat and turns into a high-pressure liquid. It then passes through the expansion valve for throttling and pressure 

reduction before entering the evaporator to absorb heat and evaporate. Finally, it returns to the compressor to complete the cycle. 

However, industrial vertical air conditioners have undergone multiple optimizations in design, such as using industrial-grade compressors, 

strengthening heat exchangers, providing corrosion-resistant shells, and installing anti-interference control systems, enabling them to 

operate stably in harsh industrial environments such as dust, oil contamination, and high temperatures. 

In the industrial field, temperature control is not only related to the comfort of employees, but also directly affects the stability of 

production processes, the reliability of equipment operation, and the consistency of product quality. For instance, in a precision 

electronic manufacturing workshop, temperature fluctuations may cause changes in component dimensions; in a food processing 

plant, inappropriate temperatures can accelerate the reproduction of microorganisms; in a chemical production area, high temperatures 

may trigger safety hazards. Therefore, industrial upright air conditioners, as important equipment for the production environment, 

their selection and application require comprehensive consideration of multiple factors. 

Performance Parameters and Core Features

The performance of industrial upright air conditioners within the cooling capacity range of 7.5kW to 50kW directly affects their applicability 

and operational effectiveness. Understanding these key parameters and features will help users make informed choices based on their own 

needs. The distinct characteristics of these air conditioners, compared to ordinary commercial air conditioners, lie in their enhanced design 

and industrial-grade configuration, which can meet the demanding requirements of industrial environments. 

The refrigeration capacity is the most crucial parameter of industrial vertical air conditioners. The capacity range of 7.5kW to 50kW enables 

it to cover industrial spaces ranging from 150 square meters to approximately 1000 square meters. The specific applicable area also needs 

to be comprehensively considered in combination with factors such as space height, heat source distribution, and insulation conditions.

Taking a model with a refrigeration capacity of 25kW as an example, its applicable area can reach 150-200 square meters, and the maximum 

air volume can reach up to 8000m³/h, which can quickly lower the environmental temperature and maintain stability. While a model with 

a refrigeration capacity of 7kW is suitable for medium-sized industrial spaces. The actual measurement shows that it can reduce the temperature 

of a workshop from 37℃ to 26℃ within 90 minutes, effectively solving the problem of frequent equipment shutdown due to high temperatures. 

The air volume parameters directly affect the air circulation efficiency of the air conditioner. Industrial vertical air conditioners usually 

have a large air volume design. The external circuit air volume can reach 2200 m³/h, and the internal circuit air volume is approximately 

650 m³/h. This efficient circulation capability ensures that the hot air in the workshop can be quickly discharged, while cool air that has 

been treated is sent in, making the temperature distribution more uniform. In precision manufacturing environments, these air conditioners 

can control the environmental temperature difference within ±1℃, significantly improving the accuracy of detection data and product consistency. 

Typical Application Scenarios and Case Analysis

Industrial vertical air conditioners, with their powerful cooling capabilities and stable performance, have been widely adopted in various 

industrial sectors. From automobile manufacturing to electronic production, from food processing to the pharmaceutical industry, vertical 

air conditioners with a cooling capacity ranging from 7.5kW to 50kW can meet the temperature control requirements of different types of 

factories and workshops.

Understanding these typical application scenarios and a specific case analysis will help industrial enterprises select the most suitable air 

conditioning solution based on their own characteristics. 

Application Case of Automobile Manufacturing Workshop

A medium-sized automotive component processing factory's stamping workshop was facing severe high-temperature issues. The workshop 

area was approximately 600 square meters, with a ceiling height of 5 meters. It was equipped with 5 large stamping machines and several 

auxiliary machinery. During summer production, the equipment heat generation led to indoor temperatures often exceeding 37℃. Not only 

did the workers' working conditions become poor, but the equipment also frequently stopped due to high-temperature protection, seriously 

affecting production efficiency. After calculation, the total heat load of this workshop was approximately 45 kW, and a temperature control 

solution with matching cooling capacity was required. 

After a professional assessment, the factory decided to install two industrial vertical air conditioners with a cooling capacity of 25kW each, 

with a total cooling capacity of 50kW. After installation and operation, the system performed exceptionally well. In a typical summer with 

an ambient temperature of 35℃, the system can reduce the workshop temperature to the set value of 26℃ within approximately 90 minutes 

and maintain stability. The uniformity test of temperature distribution shows that the temperature difference between different areas of the 

workshop does not exceed 2℃, meeting the process requirements. 

Future technological trends

Integrating intelligence with the Internet of Things is the clear development direction for industrial upright air conditioners. The future air 

conditioning systems will deeply integrate into the factory's Internet of Things, collecting real-time data such as temperature, humidity, 

and air quality through sensor networks, and optimizing operation strategies based on artificial intelligence algorithms. Predictive maintenance 

functions will predict potential failures by analyzing operating parameters and arrange maintenance in advance to avoid unplanned downtime. 

The linkage with the production management system will enable the air conditioners to automatically adjust operation modes according to 

production plans and equipment status, ensuring environmental requirements while achieving energy optimization. 

Green energy-saving technologies will continue to innovate. The widespread application of environmentally friendly refrigerants will reduce 

the impact of air conditioning systems on the environment, while magnetic levitation compressors, variable frequency drives, and other 

efficient components can further enhance energy efficiency. Thermal recovery technology will become more refined, not only providing 

hot water but also possibly directly supporting the heating needs of some production processes.
