Role of Centrifugal Fans and Axial Flow Fans in Temperature Control!

Air conditioning and temperature control systems are developed to generate the condition of comfort within the work and home premises. They control humidity, temperature and flow of air within Air conditioning systems are integrated with three various controls-humidistats, temperature control, and air stats. In this blog, we are discussing the importance of Centrifugal and Axial fans.



What Are Axial Flow Fans?

The name axial is given to these category fans owing to the air direction generated by creating them. The first electronically driven powered fans came in the market in the year 1880. Blades moving around axis flow air parallel to the axis and move air with force in a similar direction. The typical mode of axial fans is utilized to exhaust air from the process used for supplying fresh air and major spot cooling of the room, people and machinery.

Axial flow fans having four or six blades and diameters of 6-18 feet are commonly employed in air-cooled heat exchangers, however larger and smaller fans are used occasionally. The plastic fan blades are helpful for air temperatures upto 175-degree Fahrenheit, and metal blades are used for higher air temperatures.

Most frequently electric motors are used as fan drivers, however, at some frequencies turbines are also used. Speed reduction is usually accomplished with the use of V belts, high torque drive belts, reduction gearboxes.

Variable pitch fans are specially used for facilitating process side temperature control in air-cooked exchangers. The pitch of the blade is automatically adjusted for providing the required airflow for maintaining the desired outlet temperature of the process fluid.

Industrial Extractor Fans

The heavy-duty design and performance of Axial Flow fans make it suitable for every environment. They are perfectly suited as an effective means for circulating huge amount of air across the premises.

Evaporative Air Coolers—Highlights of Technology, Functioning & Maintenance

Evaporative coolers are used as an effective way to cool indoor spaces.  Also, called swamp coolers, these coolers pass it over water-saturated pads that cause water to evaporate into it. In areas with low humidity, evaporating water into air offers a natural and energy-efficient means of cooling.

Here are a few points that are necessarily important for sizing, selection, installation, and maintenance of Evaporative Air Coolers.



SIZING AND SELECTION of Evaporative Coolers

The size selection of evaporative coolers is defined by cubic feet per minute of air that is being delivered by them to the house.

     The most common range of Evaporative Air Coolers is 3000 to 25000 CFM.
     Air moving capacity: 20 to 40 air changes per hour


The installation mechanism of evaporative coolers is defined in one of two ways-

The first cooler blows air in a central location: 
Such kind of configuration is suitable for compact houses, and they are open from room to room.
Or secondly, The cooler connects with the duct-work:
It distributes the air to different rooms. This kind of configuration is required for larger houses with hallways & multiple bedrooms.
Most of the time people install down-flow evaporative coolers on the roof of their houses. However, some experts choose ground-mounted horizontal units featuring easy maintenance and low risks of roof leaks.
Small horizontal flow coolers are installed in windows for a cooling room or a section of the home. Such portable evaporative coolers work well in moderate climates, however, they are not sufficient to cool in hot climates. Room evaporative coolers can reduce the temperature in a single room by 5 degrees to 15 degrees Fahrenheit.

OPERATION of Evaporative Air Coolers India

For efficient working, and an evaporative cooling mechanism, an evaporative cooler should have a minimum of two speeds and a vent only option. The water pump does not operate, and outdoor air isn’t humidified in the vent- only operation. Other than this, it also enables you to use the evaporative cooler as a whole-house fan during the mild weather.
Movement of cooler air can be controlled through the house after the adjustment of window openings. For providing openings upto 2 square feet for each 1000 CFM of cooling efficiency, windows or vents are opened on the leeward side of the house.
If windows are open too far, the hot air will enter, and if windows are not open far enough, there will be humidity created in the home. For controlling humidity and temperature across different areas, you need to keep opening & closing the windows accordingly.

MAINTENANCE OF EVAPORATIVE AIR COOLING UNITS

If your cooler is maintained properly and timely, it saves you lots of time, work and money. Keep draining & cleaning your evaporative cooler on a regular basis and ensure periodic removal of sediments & minerals.  Every season, there should be major cleaning. Also, the more cooler runs, the more maintenance it requires. Also, pads should be replaced a minimum of two times in a cooling season.


Well! The evaporative coolers are very beneficial and economic as they require only minor to moderate setup. Other than this, it is based on basic cooling technology, known for cost-effectiveness and environment-friendly nature.

How Evaporative Air coolers differ from Air conditioners?

Evaporative Air Coolers are widely used in India. In general terms they are are also referred to as swamp coolers or desert coolers. By the way, air coolers are affordable to purchase, run and maintain. Also, they are simple in design and effective for small space. There is a tank at the bottom, an exhaust fan and three replaceable mediums for the circulation of water. The pump used for transferring water via cooling mediums works as a wall on all three different sides of an evaporative air cooler. If you are concerned about Evaporative Air Cooler In India, then look here some notable points regarding the same.



A few simple ways to let you know how evaporative Air Cooler Work?

When warm air is drawn into an air cooler, it passes through a honeycomb cooling media. As soon as it moves via honeycomb cooling media, water flowing above it soaks up the heat of air that causes evaporation of water. Then a powerful fan increases the level of cool air into the room, as a result fresh, moisturized and cool air is circulated out of the room via open door or window.

Once the hot air circulates via the wet medium, the water absorbs heat and the fan releases cool air into extensive space. Advanced models use stored refrigerant for recycling air within the ambient space. The coolant soaks heat from the air of the room air and pushes down cold air through the fan mechanism.
