In the scorching workshop, 5-50KW vertical split single-cooling air conditioners are quietly becoming the mainstay of industrial cooling. 

They can precisely lower the temperature without affecting the production process, making them an indispensable cooling tool in 

modern manufacturing.

Today, with the rapid development of manufacturing, the scale and area of factories are constantly expanding, and the demand for 

air conditioning systems is also increasing day by day.

Industrial vertical split single-cooling air conditioners, with their unique structure and performance, have demonstrated distinctive 

advantages in the field of large-space cooling, providing reliable cooling solutions for various industrial environments.

01 Advantages of Industrial Split Air Conditioners

The industrial split air conditioner adopts a split design, placing the compressor and condenser outdoors, while the evaporator and 

fan are placed indoors. This structure effectively reduces indoor noise and provides workers with a relatively quiet working environment.

Meanwhile, the split design makes the installation position of the indoor unit more flexible, allowing for a reasonable configuration 

based on the workshop layout to achieve the optimal cooling effect.

Industrial split air conditioners can be controlled in individual areas according to actual needs, avoiding the need for comprehensive 

cooling of the entire space. This targeted cooling method significantly reduces energy consumption and saves operating costs for enterprises.

The advanced refrigeration technology and energy-saving compressors adopted by the system further enhance the refrigeration 

effect and energy utilization efficiency.

02 Applicable scenarios and application industries

Industries such as the electronics manufacturing industry, the automotive manufacturing industry and the textile industry, which require 

strict control of temperature and humidity, are particularly suitable for the adoption of split air conditioning systems.

The production processes in these industries are sensitive to environmental temperature and require constant temperature and humidity 

conditions to ensure the stability of product quality.

Large warehouses and logistics centers are also important application sites for industrial split air conditioners. These Spaces need to 

effectively control the humidity and temperature in the air to prevent goods from getting damp, moldy or deteriorating.

The flexible layout feature of split units enables reasonable configuration based on the distribution of goods, enhancing the operational 

efficiency and management convenience of warehouse air conditioning.

03 5-50KW refrigeration range application

The 5KW small vertical split air conditioner is suitable for small industrial office areas or control rooms, and can provide sufficient cooling 

capacity for a space of approximately 50 square meters.

The 20KW medium-sized unit can cover a workshop area of approximately 200 square meters and is an ideal choice for most medium 

and small-sized production areas.

The 50KW large vertical split air conditioner is sufficient to meet the cooling demands of a large space of approximately 500 square meters. 

Even in large production workshops or storage areas, it can maintain a comfortable working environment temperature.

This flexible capacity configuration enables enterprises to select the most suitable model based on actual needs, avoiding problems 

such as energy waste or insufficient cooling.

04 Comparison with traditional central air conditioning

Compared with central air conditioning systems, split air conditioners have a higher energy-saving effect. It can activate the cooling 

function for specific areas as needed and turn it off when not in use, thus avoiding unnecessary energy waste.

Although central air conditioning can ensure the supply of fresh air to rooms, keeping the air fresh all the time, split air conditioners 

can also improve indoor air quality by introducing a fresh air system.

The investment cost of split air conditioners is usually lower than that of central air conditioning systems. Central air conditioning requires 

complex piping systems and machine room construction, while split air conditioners are easy to install and do not need a large number 

of air duct installations.

This not only reduces the initial investment, but also decreases the complexity and cost of later maintenance.

05 In-depth Analysis of Practical Application Cases

The total construction area of a certain mechanical manufacturing factory in the northwest region is approximately 12,000 square meters, 

among which the production workshop covers an area of about 9,000 square meters, and the highest point of the workshop roof 

reaches 14.2 meters.

Due to the local climate, which is hot in summer and cold in winter, the temperature in the workshop fluctuates greatly, affecting the 

accuracy and stability of the precision processing equipment.

The factory has selected multiple 50KW vertical split single-cooling air conditioners to be used in conjunction with the winter heating 

system, forming a year-round temperature control system. The air conditioning unit is installed in the middle of the steel column in the 

workshop. It is integrated with the fan coil unit through specially modified supply and return air static pressure boxes and air outlets. 

No air ducts are used, and the appearance is neat and beautiful.

In view of the large height of the workshop, the stratified air conditioning technology was adopted. The air flow organization is supply 

from the middle side of the workshop and return air from the bottom of the fan coil unit. Only the area below the supply air outlet is 

air-conditioned.

This solution saves initial investment and operational energy consumption. It has been measured to save about 35% of the cooling 

load compared with the whole-room air conditioning system.

After the system was put into operation, the temperature in the workshop working area was stably maintained at 26±2℃, fully meeting 

the temperature requirements of precision processing equipment. The air quality has also improved, and the work efficiency of employees 

has significantly increased.

Due to the modular feature of the split air conditioner, when the production line is adjusted, the position of the air conditioning unit 

can be conveniently adjusted, demonstrating excellent flexibility.

06 Limitations and Countermeasures

Industrial vertical split single-cooling air conditioners also have some limitations. Each split unit requires an independent outdoor 

unit installation space, which may pose a challenge for enterprises with limited space.

Multiple outdoor units need to be reasonably planned for installation positions to avoid affecting the building's appearance or 

causing noise interference.

To address this deficiency, some enterprises have adopted a centralized layout of outdoor units, installing the outdoor units of 

multiple systems in a designated area, which is both aesthetically pleasing and easy to maintain.

Another solution is to choose a multi-split system, connecting multiple indoor units with one large outdoor unit to reduce the 

number of outdoor units.

It is worth noting that split air conditioners generally cannot supply fresh air, making it difficult to ensure the freshness of the air 

in the air-conditioned room. If fresh air is needed, an additional fresh air system will be required, which may increase the complexity 

and cost of the system.

07 Selection and Maintenance Suggestions

When choosing an industrial vertical split single-cooling air conditioner, it is necessary to accurately calculate the cooling demand. 

Models with overly high specifications will lead to energy waste, while those with overly low specifications cannot meet the cooling requirements.

It is recommended to hire professional engineers to conduct load calculations, taking into account various factors such as the area 

and height of the workshop, the heat generated by the equipment, and the density of personnel.

In terms of maintenance, split air conditioners need to have their filters and heat exchangers cleaned regularly. For large Spaces, 

maintaining filter screens can be rather troublesome because there are many of them and they are installed at high positions, resulting 

in a relatively long maintenance period for each maintenance.

Choosing models with automatic cleaning functions or those that are easy to maintain can significantly reduce the cost and workload 

of later maintenance.

In the first phase of a certain energy storage power station project in Xi 'an, Shaanxi Province, 200 low-temperature heat pump split air 

conditioning units were put into operation at one time, meeting the cooling and heating demands of 200 rooms at the site.

After a certain auto parts factory in Ningbo installed 10 industrial energy-saving air conditioners, the temperature in a 2,000-square-meter 

workshop dropped from 38℃ to 28℃ within 30 minutes, and the daily output increased by 22%.

Industrial vertical split-type single-cooling air conditioners are becoming a key force in modern industrial environment temperature control 

with their high efficiency, flexibility and energy-saving features.
