Tips On Choosing The Best Air-Conditioner For Your Home

In today’s modern world, air-conditioners had seem became a necessity to one’s life other than just food, clothing and shelter. Worst, especially during Malaysia’s heat spell weather, more and more families are desperately installing or upgrading new aircons in every possible room and/or communal areas of their homes.

Hence, it’s not always the case that owning multiple and/or an oversized air-conditioner simply means cooler and cost effective. Below are 4 great tips we wish to share to you on how to select an ideal air-conditioner for your home.

 

Usually for home users, we does not recommend installing a cassette or ceiling suspended split-system (which are commonly used for commercials) due to its bulkiness, less effectiveness, waste of energy consumptions and money. Hence, a decent wall mounted unit should be sufficient for residential use.

Ideally you should choose an energy efficient air conditioning, a good 5-star certified model, not only of its cooling comforts, but could to save you a lot on the monthly bills as well.

Because of this, energy rated inverted models are now becoming more and more popular for their long term usage and durability, despite higher purchase cost.

 

2. WHAT IS THE RIGHT SIZE

First, you need to determine the square footage (SQFT) of the cooling space. Then make necessary adjustments based on the room’s circumstances e.g. facing sunset, in kitchen instead of sleeping room, 2 or more are occupying the space, etc.

Use the chart below (as references) to determine your aircon capacity e.g 1HP, 2HP or more.

3. WHERE TO INSTALL?

The sole purpose of an air-conditioner is to move out heat from your home. A good rule of thumb is to have the both below:

  1. air blowing direction of your aircon e.g angle the blower towards crowd area
  2. ensure good (free) airflow surrounding the external compressor unit, avoid installing at enclosed areas

 

Having regular maintenance is the key for durability and cool efficiency. According to the US Department of Energy, dirty filters will consume 15% more energy compared to clean ones.

Hence, easy diy e.g. cleaning the filtering nets, dusting out the blower and face plate can be done ourselves on a regular basis (once a month), while you should also engage a professional on a chemical wash procedure on a periodic time frame (12-18 months depending on the usage) to prevent nasty mould, mildew and bacteria built-up.

What is R-32 The Next Generation Refrigerant!

 

What’s R-32?
R-32 is a next generation refrigerant that efficiently carries heat and has lower environmental impact.

 

 

Refrigerant is a medium for conveying heat.

Air conditioners transfer heat while circulating refrigerant between the indoor and outdoor units.

Although there are various types of refrigerants, R-32 is a new refrigerant currently receiving the most interest.
Because R-32 efficiently conveys heat, it can reduce electricity consumption up to approximately 10% compared to that of air conditioners using refrigerant R-22. Furthermore, compared to the refrigerants widely used today such as R-22 and R-410A, R-32 has a global warming potential (GWP) that is one-third lower and is remarkable for its low environmental impact.

As the only manufacturer that develops and manufactures both air conditioners and refrigerants, Daikin launched the world’s first residential-use air conditioner
using R-32.

Refrigerant Trends

Various refrigerants have been used in air conditioners until now. Regulations have increasingly become stricter from greater consideration for the global environment because of the Montreal Protocol in 1987 and the Kyoto Protocol in 1997, resulting in a shift to refrigerants with even lower environmental impact.

Although the mainstream refrigerant R-410A has an ozone depletion potential (ODP) of 0, its global warming potential (GWP) still remains an issue.

While R-32 also has an ozone depletion potential of 0, the refrigerant has only approximately 1/3 of the GWP of R-410A. Consequently, investigation of this promising next generation refrigerant has increased.

However, because R-32 had been an extremely difficult refrigerant to handle, its use was not practical until now. Daikin became the world’s first company to succeed in applying R-32 to air conditioners by leveraging its expertise as the only manufacturer that develops and manufactures both air conditioners and refrigerants.

Currently, R-410A is the refrigerant most commonly used in developed countries. However, if all R-410A were converted to R-32, the impact to global warming from HFCs in 2030 would be reduced by the CO2equivalent of approximately 800 million tons (19%) compared to the continued use of R-410A.*2

Cooperation with governments and international organizations has expanded technical assistance for emerging countries to each region and aims for widespread use of the refrigerant R-32 throughout the world.

Aiming for widespread use throughout the world, Daikin not only manufactures and sells R-32, but it also provides technical assistance in emerging countries in cooperation with governments and international organizations.
In India, verification tests were conducted for inverter type R-32 air conditioners. In executing training for the proper handling of R-32, the technical level also improved. Consequently, Daikin has received requests from various governments, including the Thai and Malaysian governments, and the company is beginning to target local manufacturers for technical assistance for conversion to R-32.
Such efforts as those mentioned above have earned Daikin high acclaim and a variety of awards.
