Centrifugal Fans and Axial Flow Fans-Some typical Introductory points to elaborate their significance

The objective behind the introduction of the air conditioning system is to generating comfortable conditions by controlling humidity, temperature, and airflow within the rooms. AC systems are fitted with three different controls- humidistats, temperature control, and air stats. Let us have a quick look at the utility and significance of Centrifugal and axial flow fans.

A significant Highlights on Axial Flow Fans

Axial flow fans are named for the direction of airflow created by them. The first electrically powered fans were introduced in the year 1880. Blades circulating around axis drive air in parallel to the axis and draw air forcefully in the same direction. In a typical mode, Axial fans are specially used to exhaust dirty air from processes that supply fresh air and general spot cooling of people, room and machinery.

 → Axial fans generate air flow with a high flow rate it means they’re in the process to create a large volume of airflow. However, they need to create airflows of low pressure but they need a low power input for better operation.

→ Axial Flow fans also are known as industrial axial fans use propeller for drawing air into the fan and discharge it in the same axial direction. Common influences of industrial axial fans are tube axial fans, panel fans, air circulators, and personnel coolers.

And that is the reason you want installation or replacement of the Air Conditioning System to be done right the first time. But when it comes to visualizing in real life, it is not practically possible that consumer gets a perfect replacement at a single effort. So many variables lay a direct or indirect effect on the successful implementation of the Centralized Air Conditioning System within the premises. The variables like size and design of premises, way of system installation and construction of ductwork, etc.are some direct means to affect the installation process.

The latest survey conducted on more than twenty thousand users of the centralized air conditioning system installed by them reveals some major points. The report describes which parts break and what does it cost to fix central AC at the time where repairing is required.

By the way, the segment of air-conditioning and refrigeration is having a very vast application with diverse application requirements. Some important terms related to airconditioning systems are:

Unit

The unit of refrigeration is a ton, which is a time rate of cooling equal to 12000 BTU/Hr.

Refrigeration cycle

The major components of the vapor compression cycle are a condenser, thermostatic expansion valve, and evaporator. The refrigerated gas enters into the compression at low temperature and low pressure where it is compressed by leaving compressor at high temperature & pressure.

Equipment used in Centralized Air Conditioning System

1-Compressor-

Sealed, semi-sealed and open type

2- Condenser

Generally, the condenser is made available in two types of design- Water cooled type design or air-cooled type design. Water-cooled type condensers are in the form of tube or shell construction, whereas air-cooled condensers are an assembly of finned tubes through which refrigerant flows & rejects air heat.

3-Evaporator

When the medium of cooling is air, the evaporator type is called a direct expansion cooling coil that comes along with finned construction. In this system, air flows over the tubes and the refrigerant flows through the tubes. When the medium is water, the evaporator is called direct expansion chiller

4-Cooling coil

There are two types of cooling coils direct expansion or chilled water type. The cooling coil has finned tube construction where refrigerant gas or chilled water moves via tubes & air is driven over the tube surfaces. Fins are specially used to increase the effective heat transfer area. Once the refrigerant flows via tubes, the cooling coil is converted as a direct expansion cooling coil.

5. Air Handling Unit

Air handling units have a cabinet type sectionalized construction specially used in air conditioning applications. It is connected with other equipment in the refrigeration circuit through the cooling coil.

Apart from these five major units, other auxiliary equipment like a cooling tower, pump sets, ducting, piping, insulation work, etc., are required for completing the installation of the Air Conditioning plants. For the installation of central plants, there is the requirement of two separate areas-Condensing unit and Chilling Unit.

To keep the Air conditioning system working properly for a long time four tips should be followed by the users:

●      Keep it clean

●      Seal and insulate ducts

●      Seasonal checks

To make work or home premises comfortable for workers and ensure proper incoming and outgoing of air, these systems play a very significant role. Centralised Air Conditioning System has been enhancing the quality and lifestyle from several years till now. In a formal and sure shot language, Air Conditioning is defined as the process to condition humidity, temperature and ventilation in buildings.

Here we are describing some common problems & repairing of central air conditioning systems.

Tips to Troubleshoot central air conditioning system

If at a sudden, your centralized airconditioning system loses your cooling power you might be able to find out the causes by yourself, however in certain cases you will have to contact an HVAC professional for better assistance. Well! Here are a few tips which will help you know everything about your home air conditioning system, and thus troubleshooting will become easy for you.  There might be a problem with Refrigerant, Compressor, Condenser, Expansion Valve and Evaporator coil. Sometimes there might also be an issue with the thermostat. The recommended way to start troubleshooting is to start with analyzing the symptoms of lost performance.

 

1. If AC system does not switch on

Potential reasons

If you’re not able to activate air conditioning system, the major possibility with the problem is with tripped circuit breaker or blown fuse, fault in thermostat or internal switch is switched off.

Potential solutions

●      Check whether thermostat is in cool position & isn’t positioned to off.

●      Also, be sure that the thermostat is set below current room temperature

●      Check that 240 volt circuit breaker controlling air conditioning compressor and 120 volt circuit breaker controlling furnace blower are switched on.

●      If circuit breaker trips or fuse blown, then reset circuit breaker or replace the fuse.

●      If these steps do not work, the possibilities are of serious issues like short circuit. And in such condition, you need to contact technician for relevant assistance.

2. Poor airflow from cooling vents

Potential Reasons

Due to unclean air filter or ductwork airflow there might be condition of dirty airflow.

Potential Solutions

●      Check whether air filter in handling system  is clean. Replace it quick and replace with new clean air filter.

●      Check complete ductwork very precisely in order to ensure that it is neither disconnected or crimped.

●      Register dampers on vents in rooms in order to ensure that they are completely open.

3. AC does not humidify the air in Oversized systems

Potential Reasons

●      Failure to fight with humidity can be caused by air conditioner that is very large for house.

●      If your system fails to sufficiently dehumidify and it short cycles an oversized system might be the reason.

●      A system that is oversized cools the air very fast that system is shut off by the thermostat before a sufficient amount of humid air makes its way around the cooling coil to get dehumidification.

Potential Solutions

●      The solution is to replace the condensing unit & coils with sufficiently sized system.

●      As a next alternative step you can also use an artificial way to cool load like extend air conditioning to our garage or basement space with additional ductwork.

4. Insufficient cooling through a long cycle of compressor

Potential Causes

Insufficient cooling coupled with long ON cycle of compressor is a sign-in of a worn-out compressor that which has lost the ability of compressing refrigerant.

The compressor is received in outdoor housing unit, and when you listen it excessively running without cool air flowing within the house, you will come to know that you have an issue.

Potential Solutions

Contact a genuine technician and let him check the compressor and replace the part if required.

How Evaporative Air Cooling Technology is better than conventional air conditioning?

The last 100 years observed the height of massacre which can be done by humans to Earth's natural resources. More than 50% of rain forests were cleaned up, ozone layer depleted and fossil fuels are near exhaustion. All such hazards collectively gave birth to a critical situation called global warming. To lessen the hazards due to environmental pollution, scientists have been continuously making effects to invent some technological alternatives. We EvaporativeAir Cooling Technology is one among several technological alternatives that are playing a significant role in reducing environmental pollution.

Conventional room air conditioners (ACs) are based on state of the art cooling technology, but some experts don’t think it as advanced as it should be. Even modern room air conditioning systems are not much effective as they consume 5% of the county’s produced electricity.

Some air conditioners use chemicals as coolants for less consumption, but they are still not environment-friendly. Then what is the substitute? The answer is Evaporative Air Cooler in India.

Evaporative Air Cooling Systems

An Evaporative cooling system is a wonderful substitute for an air conditioning system in order to deliver a comfortable environment in hot & dry climatic conditions.

Such kind of air cooling systems deliver a greater cooling effect when the following conditions are available:

1. Humidifier air draft is directed over the body of work person or in working zone.
2. Exhaust fans positively exhaust old polluted air to the outside atmosphere
3. Atmospheric space has comparatively high temperature and low humidity

Major Significances of Well build Evaporative

Effect of chilling wind

The airflow generated through fans decreases the effect of chilling wind felt by the body. The chilling effect of wind is specially used for increasing heat loss rate from the skin surface.

Productivity improvement

As per the data collected from researches, a comfortable working environment for work persons improve overall productivity. Evaporative Cooling Systems based on direct evaporative cooling technology makes the environment free from stress related to increasing temperature.

Comfort zone for human

Comfort zone for a human is defined as the situation that most people find a very comfortable environment to work in.

When it comes to calculating the viability of Evaporative Air Cooling Systems Noida in comparison to other control systems, they provide highly efficient temperature relief for all industrial and commercial environments. Also, they can be very economical; up to 80 percent in comparison to conventional cooling systems.

Pressurization and Ventilation Systems

Ventilation systems are specially used to provide air circulation in abundance to ensure the comfort of the people. Some kinds of ventilation systems are a kind of dry ventilation system where no cooling is done. In certain cases, ventilation systems are installed for pressurizing the area.

Pressurization systems

The pressurization systems are used as a special utility to pressurize the enclosed space to keep comparatively high pressure than the area just adjacent to it. The purpose of this arrangement is to reduce the possibilities of internal leakage of air, gas & smoke.

The pressurization systems have the following considerations in particular:

●      Supply filtered air in an enclosed area

●      Pressure relief system for avoiding over pressure

Ventilation Systems

Ventilation systems are found essential equipment in terms of maintaining the air circulation and temperature within the working premises. They move outdoor air into a building or a room and circulate the fresh air in the room. Concept of ventilation is defined to provide circulation of healthy air by diluting pollutants & removing pollutants from it.

Major elements of ventilation:

The direction of airflow- The direction of airflow within the work premises should be from clean areas to dirty areas.

The pattern of airflow- The extern air should be carefully delivered to each & every part of space is quite an efficient manner of removing airborne pollutants.

Rate of ventilation-The amount and quality of outdoor air made available in space is called the rate of ventilation.

Pollution Control Equipment

Air pollutants are generated via different natural and or man-made sources and activities. However, pollution-causing elements are derived from both mobile & stationary sources, but here we are gonna discuss the pollution impacts on industrial premises. The environment protection agency imposed certain rules and regulations on sources of air pollutants to reduce their effects on the atmosphere. There are various kinds of air pollution control equipment to handle air pollution within the industry premises.

Some types of air pollution control equipment applied to industrial applications are:
