Five Basic Elements of Air Conditioning System


It is known as the air conditioning system engine and it functions together with a substance to transform the gas into a liquid. The main function of these basic elements of the air conditioning system is to convert low-pressure gas into a high-pressure gas, which also has a high temperature. In this compression process, the gap space between molecules get narrowed down, creating as gas called energized gas. now, the energized gas comes out of the compressor to enter into the condenser.

Condenser Coil

Fitted into the condenser coil which main function to cools down the high-pressure gas and converts it back into a liquid. The main function of the condenser coil is taken to the next part of the air conditioner named as the evaporator. Both compressor and condenser on the outside of your house that you can also see.


It is located  inside the centre house of air conditioning system that usually found near the furnace. With an extremely thin pipe, it is linked with the condenser. Now the high-pressure gas changed into the low-pressure liquid. The decreasing pressure in this section turns the liquid into a gas again. In this evaporation process, the working fluid takes away the heat from the air and cools it off. now the working comes out of the evaporator in the form of a gas to again get compressed by the compressor. All this process happens cyclically.

Air Handler and Blowing Unit:

Both parts of air conditioning system work together to draw room air to the evaporator and disseminate the cool air all over your house. With the help of a duct system, the path of airflow in the room is facilitated.

Thermostat: It is used to maintain the temperature by regulating the heat energy flowing inside and outside of it. Thermostat can be set automatically or manually, depending on the features element of air conditioning system.

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

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.

evaporative air cooler in india

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

INSTALLATION of Evaporative Air Coolers in India

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.


If your cooler is maintained properly and timely, it saves you lots of time, work and money. Keep draining & cleaning your evaporative air 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.

ventech systems

Pre-installation evaluation

Before the installation of any air conditioning system, the first important step is to calculate the J-load calculation manually. Through this calculation, the contractor knows how much heat is received by your house, and what size of conditioner will be needed to maintain it cool.

Ductwork and design

Once manual J-load calculation is done carefully, secondly the contractor should check systems associated with air conditioners that are reliable for the application. At the same time, it is necessary to ensure the central air handling capability of ductwork. The quality of ductwork much more depends on its design.

The Central Air Unit

After the evaluation of home performance and support systems, now comes the time to select an air conditioning unit. The size and structure of your premises depending on the following types:

  • Split air conditioning systems
  • Packaged central air systems
  • Heat Pumps

Installation and Labor

The business size of air conditioning system contractors and their location are two factors that may affect the installation cost of central air conditioning systems. According to the research, half of the HVAC systems are not installed correctly that’s why their efficiency level is decreased by up to 30%. That’s why finding the right contractor is very important if you want to save both time and expenses.

If you are in search of the right contractor, then here are a few points you need to take care of:

  • Check their website, history, work history, and online reviews
  • Compare  three different companies to find out what is exactly right for you
  • Ask them about their expertise, certifications and quality standards

Tips to control installation costs of air conditioning systems!

  1. Carefully examine your cooling needs-

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.

How Does An Evaporative Cooler be Different From Air Conditioner?

Parameters Evaporative Cooler Air Conditioner
Cooling Mechanism Water evaporation mechanism to cool incoming hot air Use compressor and refrigerant for cooling air
Level to temperature reduction Moderate High
Air Ventilation Excellent Poor
Energy Consumption Low High
Portability Portable Fixed
Dust Filter Yes Yes
