- What Technology you Must Prefer for Air Conditioner
3 Questions you must answer to select a suitable Air Conditioner.
To decide the specific type and size of an Air conditioner, you must answer the following three questions.
1. In what space will you install your Air Conditioner unit?
What are different types of Air conditioners, each designed for the specific installing condition?
Wall Mounted Split AC
The most common type of air condition commonly used is Wall Mounter Split AC. This AC consists of two parts – indoor and outdoor. The indoor is mounted inside the room of the wall most appropriate height to mount the indoor is 6-8 ft. to get the best AC performance and faster cooling. The outdoor also have a pipe outlet from which it releases the moisture content from the room. While installing the indoor, the way for this pipe outlet must be predefined defined. The outdoor is placed outside the room where it releases the heat. The mount must be placed in a windy area to improve AC performance. The outdoor must be placed above the high of indoor to minimize the compressor work.
Typical applications include bedrooms, offices, apartments, and shops.
Floor Standing Split AC
Floor Standing Split AC is also called cabinet or column type AC. These are high capacity units
cooling capacity of 2 tons and more than 2 tons. These are used in large rooms where several wall-mounted ACs can not be used. This AC provides strong flow and longer throw of cool air, which means that these ACs can not be installed with occupants in close range. These ACs also include indoor and outdoor units with working and outdoor positions similar to the Wall Mounted Split AC.
Typical applications include Malls, Mosques, waiting areas and receptions, lobbies, large auditoriums, and halls.
These AC units are enclosed into a single box with all the components installed. These are installed into a window cut through the so-called window AC wall. They provide a high coefficient of performance at the expense of several limitations. You must have exterior support for the window air conditioner. You must solve the dripping water problem. Inserted into window opening of the wall. Only specific windows exposed to open environments can be utilized. Not all windows are suitable.
Typical applications include single bedrooms, offices, and small apartments.
This AC is also enclosed into a single box. It is portable to move it from one room to another room. It’s a floor-standing small unit with a long duct to exhaust hot gasses and water. This duct or pipe is placed outside the room through a window, door, or another opening. It is designed for small rooms and has a cooling capacity of up to 1 ton. The main reason to choose these types of AC, due to their low price and portability.
Typical applications include hostels, single bedrooms, small apartments, and any other congested place where you can’t install the above three types of ACs.
2. What Air Conditioner capacity do you require for your room size?
The most common choices of available 0.75 ton, 1 ton, 1.5 ton, and 2 ton. Here is a thumb rule to choose your Air Conditioner capacity in tonnage according to the room size.
- 0.75 ton AC is advised for room’s floor area less than 80 sq ft. Usually small bedrooms and office cabins.
- One ton AC is advised for the room’s floor area ranging from 80 sq ft to 120 sq ft. Usually for medium-sized bedrooms/rooms and large offices and shops.
- 5 ton AC is advised for the room’s floor area ranging from 120 sq ft to 190 sq ft. Usually large master bedrooms or conference rooms.
- 2 ton AC is advised for the room’s floor area ranging from 190 sq ft to 300 sq ft. Usually in living rooms and medium-sized halls, larger offices, and more extensive shopping stores.
3. What is the Power Source?
All the Air conditioners are suitable for AC (Alternating Current) power supply. But if you want to use solar or UPS as an alternative power source, you must consider DC Inverter AC as your only option.
What Specifications you must look for in an Air Conditioner
Following are some specifications you must look for while selecting an Air Conditioner
With rising prices, electricity bills are one of the most common concerns in Pakistan, and with the rising temperature intensity, Air Conditioners are becoming a necessity, day by day. But the moment an Air Conditioners are installed in the house; electricity bills increase significantly. With the selection of suitable Air conditioners, you can save a significant portion of your electricity bills. Today modern DC Inverter AC can save more than 60% of electricity consumed. So, it is highly recommended to choose an AC with higher Energy Saving, to save electricity bills.
Today in Pakistan four most commonly used refrigerants in home appliances are R-22, R-134a, R-400a, and R-600a.
Some old Air conditioners still use R-22 refrigerant. R-22 hurts the Ozone layer and global warming. Also, the R22 gas has been banned by the United States Environmental Protection Agency (US EPA). So, we don’t recommend appliances with gas R22.
R-410a and R310a
Today in Pakistan, the most common refrigerant used in air conditioners is R-410A. This refrigerant is better than R-22 in terms of Ozone Depletion Potential (ODP) and energy efficiency but has high global warming potential (GWP). The same is the case for R-134a, which is also HFC-based gas. It also has zero ozone depletion potential and has a less harmful impact on global warming than R-410a.
The greenest refrigerant available today in the Pakistani market is R-600A. R-600a is HCFC based gas that has zero ozone depletion rate and near-zero global warming potential. They also have high-energy efficiency but are highly flammable as they are hydrocarbons. Still, they are the most eco-friendly refrigerant available in the market. This refrigerant has started to grow its marketplace in Pakistan; it can now be found in refrigerators but is still rarely found in any Air Conditioner.
So, highly recommend appliances with gas R-600a.
The table gives the ozone depletion potential (ODP), global warming potential (GWP), and Atmospheric life of commonly used refrigerant gases.
The SEER rating is essential when comparing central air conditioners and seasonal energy efficiency ratios. Mostly it is ignored, but if you want to find it, you can visit official websites to see it. The SEER rating measures how much energy the air conditioner uses to cool a home. Experts recommend that people in hot and humid climates choose an air conditioner with a SEER of at least 15. The common SEER rating ranges from 13 to 24.
Air Conditioner is a heavy dent in your pocket, so you want it to last longer. One of the ways that companies claim the quality life of any product is by warranty. You must see for Air Conditioners with a more extended warranty.
The built quality of an air conditioner is checked in terms of the material it uses for evaporator and condenser and the Technology they utilize for the compressor. Best evaporators and condensers are made up of copper coils. Also, double-layered copper condensers are highly recommended for condenser technology. In terms of compressor technology, you might want to buy the product with the latest Technology claimed by the specific company. Because it’s hard to compare the compressor technology of different companies as every company might claim the best Technology.
One of the latest features in any home appliance is the Smart Feature. It allows connectivity of your device to the internet to perform specific tasks. Wi-Fi connectivity allows you to access the AC from remote places for air conditioners. You can also control your AC if you’re not even present at a particular place. For example, you might want to turn on your Air Conditioner using Wi-Fi when you leave the office, so you find your room excellent comfortable when you reach home. An innovative feature also allows you to monitor the performance of your Air conditioner.
Another important feature you might want to look into is the price of the Air Conditioner. It is recommended to buy a low-price Air Conditioner if you are stuck between two options with similar features and performance. Also, there is not a lot of development in the field of Air Conditioner technology, and mostly Air conditioners are similar in terms of performance, so price plays an essential role in deciding.
What Technology you must prefer for Air Conditioner
Two leading technologies exist in the world of Air Conditioners. One is DC Inverter, and the other is Non-Inverter. Experts recommend that users choose DC Inverter AC despite its higher price because of high energy saving, long life, low noise, and many other features.
