Comparison of Split, Window and Portable ACs

1. Space Requirement

The first aspect in Split AC vs. Window AC vs. portable AC is the space requirement of each model. Space requirement is most important in the case of the window and split AC since both need to be mounted. A split AC has more space requirements. It is divided into two units, and the internal unit is pretty broad.

A window AC also requires significant space to be mounted. You need to have sufficient window space to install the same.

A portable AC, on the other hand, does not concern much with space. You can position it anywhere as per convenience. However, it will be ideal if a venting source is present nearby. If lack of space is a problem for you, then it will be good to go for a portable air conditioner.

2. Weight

It is evident from the table that a split AC has lesser weight than the window and portable ones. But this is taking into account the weight of the internal unit only. Split ACs are divided into two units, the internal and the external. The external unit is much heavier than the internal one.

Window and portable ACs are single-unit appliances. This accounts for their higher weights. A window AC is difficult to install because of this weight as well. Although a portable AC is heavy, it can be easily handled due to its design.

3. Power consumption

The power consumption of the AC mainly depends on the type and technology of the compressor. The air conditioners with inverter technology are known to be the most efficient in terms of power consumption. A 5-star rating means an AC is more energy-efficient than a 3 star one.

When you compare the power consumption of a window AC and a split AC, the latter consumes less power for a similar star rating. Apart from star rating, you should also know about the BEE, EER, ISSER, and COP of an air conditioner.

This can be attributed to the design and host of features provided in the device’s body. A typical portable AC also consumes more power than a window AC. Although it is less expensive to afford a portable air conditioner over a split AC, the cost incurred on the electricity bill is a significant one. Use the AC energy consumption calculator to get a clear idea.

4. Noise and vibration

The generation of noise and vibration by an AC during operation can be very irritating. This was a significant problem in earlier days. Since then, technology has been used to cancel the noise produced by the operation of an AC.

Today, split ACs are guaranteed to be noise and vibration-free by many Indian Brands. This is the primary concern when they are being produced.

Depending on the model, window ACs can generate some significant noise which is sometimes more than a Portable AC during operation. For this reason, it is not a very common appliance observed in households.

4. Cooling space

Cooling space for a particular AC dictates the space that can be effectively cooled. This varies from model to model and depends on the tonnage of the AC as well.

Generally, a split AC has the highest cooling space for medium-sized rooms. If you need an air conditioner for a larger space like a drawing-room, you might like to have a Tower Air Conditioner.

Window ACs and portable ACs have lesser cooling spaces owing to their design. The effective cooling of the space depends on its nature. Cooling might take a much longer time if there are a lot of objects or too many individuals.

5. Durability

Most Air Conditioners come with a 5-year or more warranty on the compressor. These days, the bodies of the ACs are crafted with very durable plastic that ensures the long-lasting of the product. However, to ensure durability, proper maintenance is required by the customer.

This includes proper cleaning of the filter and compressor of the window and split AC. You can learn about the frequency of these clean-ups from the manufacturer. Nowadays you need not worry about maintenance if to give AMC to the manufacturer.

In the case of portable ACs, there is the need to empty the drain tanks regularly. This is crucial for the efficient functioning of the appliance.

6. Installation

Proper installation is required to ensure the efficient and appropriate working of the AC. In the case of the installation of a split AC, you need support from the manufacturer. During the installation of a window air conditioner as well, professional support is required. Notably, assistance is required from the exterior of the room.

If these appliances are not properly installed, they can go through fault operation. A portable AC, on the other hand, does not need any installation for the indoor unit. This is owing to the design and the working of the air conditioner.

7. Airflow volume

As you can see from the table, the airflow volume of each AC type is measured in CFM. This is a measure of the effective cooling capability of the appliance. Usually, a CFM reading of 300 to 450 is ideal for a 1-ton AC. Today, brands produce their products intending to provide excellent CFM values.

As you can see from the table, the window AC has an outstanding CFM value. In comparison, the split and the portable variant s have lesser CFM values. But these values are pretty significant, given the tonnage of the AC is 1-ton.

8. Refrigerant type

There are mainly three types of refrigerants used in air conditioners, the R-22, R-32, and the R410A. Traditionally, the R-22 and R-32 refrigerants have been most used in appliances. R410A has been accepted as the industry substitute only as late as 2020. It is less reactive with the environment and is dependable. It cannot be, however, used in R-22 systems.

As we can see from the table, the window and the split models use the R-22 refrigerants. The portable one, however, uses the R410A type. Although R410A is the new substitute, the R-22 is still pretty relevant among manufacturers.

9. Outdoor Unit

The final point to compare a Split, Window, and Portable AC is the outdoor unit. Out of the three, the split AC is divided into two units, the indoor one and the outdoor one. However, the outdoor unit must be within 30-meter of the indoor unit.

Window and portable ACs are both single-unit appliances. Some portable air conditioners also come with an outdoor unit. This makes it easier to manage but increases their weight significantly. Window ACs automatically drain the water outside.

Portable ACs come with ducts that are used to vent the AC manually. Regular venting is essential to ensure proper functioning.
