The selection of air conditioners for industrial use has a number of features compared to the selection of household air conditioners. It is often about large areas, large dimensions of equipment, complex installation, the ability to install individual settings for a large number of rooms. The cost of an error here will be quite high – from the failure of an expensive air conditioner to damage to material values ​​and the health of people.

Industrial air conditioners are developed to service areas of more than 300 square meters. They are often installed in buildings where an individual micro climate is required for each room – in hotels, shopping centers, banks. What industrial air conditioner will solve your problems?

Industrial air conditioning systems. Device, features and types

Despite the fact that industrial air conditioners have been produced for more than 100 years, at present only five types of them can be distinguished.

Multi zone VRF and VRV air conditioning systems

VRV and VRF are two names for the same industrial systems. This multi-zone air conditioning system includes up to 64 indoor units and from one to three external. The maximum total length of inter block communications is 300 m. The maximum height difference is 50 m. For each indoor unit, you can set your own indoor temperature and provide an individual micro climate.

The error of the set temperature is only 0.5 o C.

Chiller-Fan Coil System

The system “chiller-fan koil” is characterized in that inside the building is used not coolant, but water or antifreeze. The central chiller is called the chiller, and the heat ex changers in the rooms are fan coil units. The system compares favorably with the fact that the maximum distance between the chiller and the fan coil is practically unlimited, water flows through ordinary pipes.

Central and roof conditioners

Central air conditioners are multi functional. They can be used as air conditioners, ventilation systems, air purifiers and humidifiers. They are called central because the air is processed in the central module and then distributed through the ducts to the rooms. The central air conditioner can serve several rooms or one large one – a theater hall, an indoor stadium, a production hall. Installation of industrial air conditioners of this type and laying of communications for them are characterized by increased complexity. If possible, it is better to choose a simpler to install roof air conditioner. Unlike the central air conditioner, which requires an external source of cold, the roof air conditioner is a mono block.

Cabinet air conditioners

This type of industrial air conditioners is designed to maintain a constant temperature over large areas for a long time. Cupboard air conditioners are mono block and with a remote condenser.

Precision air conditioners

Precision air conditioners are characterized by high accuracy of maintaining the desired temperature and humidity. They consist of outdoor and indoor units. Work in wide limits of power – from 5 to 100 kW.

Comparison of industrial air conditioning systems

When selecting industrial air conditioners, many parameters need to be taken into account, including the type and configuration of air conditioning zones, the nature and change of heat load, etc.

Power consumption

The minimum level of power consumption in multi zone VRV and VRF-systems. However, the various components of the industrial air conditioning system, for example, a chiller or a separate fan coil, can be selected taking into account the minimum energy consumption. Although high power consumption traditionally distinguished central and roof air conditioners.

Ventilation option

The industrial system differs in that you can set any configuration depending on the task: you can also integrate a central air conditioner into the chiller-fan coil system and you will get a system with ventilation. The multi zone system and the chiller-fan coil system can be additionally equipped with central air conditioning or ventilation systems. This will provide full and adequate ventilation.

Cost of

You can buy an industrial air conditioner fairly inexpensively, but you should take into account the complexity of installation, which, in turn, depends on the complexity of the technical task and equipment configuration. Rooftop air conditioners are the most low-cost, but installing them can take a lot of time and money. It should also be borne in mind that large industrial air conditioning systems require maintenance personnel.

Features

In the central and roof conditioners it is not possible to adjust the set parameters for each room individually.

To fully understand the problems of selecting expensive industrial equipment for air conditioning and ventilation, engineering education and experience in this field are required. However, pre-orient in the terminology and principles of operation of air conditioners, as well as anyone can ask competent questions to a specialist.

Industrial Chiller – Select that meets all of your cooling needs

In an industry where there are machines running full throttle all day, there is a crucial need for chillers. A plethora of reputed brands offers a top class of industrial chillers. These chillers come in several models and variants – water-cooled chiller, portable chiller, and the air-cooled chiller that has different applications and uses.

Industrial chiller is ideal for heat removal. It ensures to make the temperature of the place low and keep it cool for quite some time too. It is eco-friendly and this is why today, machinery is opting for such type of chillers. They help in cooling industrial area, while few others help in removing heat. They are available for use across various industries, plastic, and printing.

However, one has to remember a few points while choosing industrial chiller.

Keep the area in mind: How big is the area that one would need to cool? There are chillers that offer low temperature for the area as per the requirement.

Understanding chiller’s requirements and necessities: The water-cooled requirements would need proper water quality, and the heat recovery is not practical. The air-chilled cooler does not require good quality of water and yet; the heat recovery would need to be practical.

Paying attention to the ambient air: Since it is where the industrial chiller sends the heat air out of the room, it is necessary to keep a check. Heat loads vary with every style of chiller and hence; one must spend some time to read about it before buying.

Controller: It controls and maintains the required temperature of room or industrial area and hence; one cannot ignore its importance.

Fluid for cooling: Will it be tap water or distilled water that would be used for a chiller? Distilled water based industrial chiller might not be the preference of many. So select the chiller of tap water or distilled water-based chiller as per the choice.

Heat requirements: Know the heat load that the area would require. Calculating the heat load is easy by checking the BTU/hr. That is to say, to heat 1lb of water, 1 degree of Fahrenheit is necessary. This BTU/hr conversion is essential to understand the heat load that the chiller shall successfully use.

Compressor: The pumping device helps to pressurize the gas and make the room cool. So, lastly, check its condition and even a condenser to ensure that the industrial chiller runs on for a long time. Moreover, check that it increases the life of machinery in the industry.

Metering device: To ensure that the metering device is working smoothly, it is necessary to learn about it before shopping for the industrial chiller.

The market of industrial Ventilation and Air Conditioning

According to most industry experts, the market of industrial ventilation and air-conditioning peaked. Manufacturing companies that supply goods to “assembly line”, and trading companies that buy goods from foreign manufacturers offers a complete package of services from design to delivery.

This diversity of providers has led to a wide range of products on the market that is not always in demand by consumers. Known manufacturers of equipment for industrial ventilation and air conditioning can offer solutions that are already being implemented to have the highest level of energy efficiency, but unfortunately, they are not in demand on the market due to higher initial investment.

The market of industrial ventilation equipment more transformed, if earlier in the growing market there was a large number of brands, the average share was about 3%, it is now possible to identify the lead five operators with a market share of 5 to 8% each. It speaks about strengthening the position of reliable companies, and withdrawal from the market of small or targeted at long-term cooperation between the companies. ”

70% of total consumption is used for shopping malls, water parks, office buildings, parking lots, banks, sports complexes. 20% of the total volume occupied by industrial enterprises, which include major manufacturing plants and pharmaceutical plants. The rest (10%) – private customers, which establish a system for building swimming pools and large residential building.

A trademark is not always a guarantee of success and a guarantee of long-term operation of the system. Even the most expensive high quality equipment may not work properly if the design or construction works were carried out correctly.

Market experts believe that in the near future the company-customers move from the selection of HVAC systems on a price basis to a choice based on an analysis of the operation of such systems in the future.
