In general, there are 5 types of air conditioning used widely in residential, office and commercial buildings.

Here are the 5 types of air conditioning:

 

Wall Mounted

Compact and compact, it is ideal for small bedrooms such as bedrooms and a limited living room.

Advantages: • Modern design with a variety of options. • Has additional features. • Easy to install. • Readily available.

Disadvantages: • Not suitable for heavy-duty use.

 

Cassette Ceiling

Ideal for small rooms like bedrooms OR larger rooms like offices, restaurants and meeting rooms

Advantages: • Suitable for installing both small and large rooms. • Good ventilation with 4-dimensional flow.

Disadvantages: • Require ceiling plaster or sufficient space for ceiling cassette unit.

 

Floor Standing

Provides strong winds, ideal for high traffic areas such as shops, restaurants and more.

Advantages: • Easy to install and you don’t have to worry about installation as it can be laid on the floor. • Quick cooling due to its large fan produces stronger winds.

Disadvantage: • Limited use of space.

 

Concealed Ceiling

Air conditioners hidden on or in the ceiling, ideal for rooms without disturbing the interior.

Advantage: • The space looks neat and clean with no air conditioning unit.

Disadvantage: • Hard to install because they are hidden in the ceiling. • Difficult to do maintenance work.

 

Portable Air conditioner

Can be placed anywhere. Just install the plug and you can continue to use it!

Advantage: • Compact. • No installation required. • Can be used both indoors and outdoors.

Disadvantage: • Can only be used in small to medium sized spaces. • Not very efficient when used outside the building. • Sound greater than Wall Mounted because compressor is in air conditioning unit. • Need to heat the released air.

 

The use of air conditioner (AC) in other less developed countries

Do you know the usage of air conditioner in other less developed countries? One of the country interviewed was Indonesia. Out of the 100 families it is estimated that only seven use AC. The reason, besides the price is still quite expensive, the electricity consumption is also high. 1 PK capacity AC only has the first electric power of 800 watts, even though not all houses have large electrical power.

Later AC manufacturers tried to overcome this obstacle by launching low wattage AC, aka low power AC. Which launches include Sharp, Panasonic, and Samsung. The consumption of low wattage AC electricity is only half that of ordinary AC. Sharp AC consumption for example, only 330 watts, Samsung 390 watts, and Panasonic can up to 175 watts.

In order to reduce electricity consumption, the AC-AC is equipped with a technology called an inverter. That is a kind of power conversion circuit to control electric current, voltage, and frequency of a device.

For example, Panasonic CS-S12GKP AC. This type of air conditioner if turned on and has reached the desired temperature does not immediately die. Unlike non-inverter air conditioners, the air conditioner will turn off if the room temperature is cold and live again when the room decreases its coolness.

Low wattage AC from Panasonic needs electricity 175 watts – 1140 watts. When the AC works to reach the desired temperature, the electricity consumption is large. Once the temperature is reached, the electricity consumption will decrease. “Turning the motor in the AC will gradually adjust to adjust to the room temperature so that the energy needed is small,” he explained.

 

Similar to an inverter

Samsung Low Wattage does not use an inverter but only adopts an inverter-like technology called good sleep mode. This air conditioner is able to keep the room temperature more stable, the temperature does not rise or fall suddenly. “Sleep can be sound because people don’t feel hot or cold”. Therefore this air conditioner is suitable for people whose sleep patterns have problems due to room temperature.

For homes with only 900 watts of electricity, please use Sharp Sayonara Panas which only needs 330 – 130 watts of electricity. Sayonara can operate in low voltage by relying on inverter-like capacitors to accommodate electricity. When the voltage drops, the AC uses electricity in the capacitor.

Sharp issued two types of low wattage, AP5HHL and AH-AP5HML. Just like other Sharp AC products, Sayonara Panas is equipped with the sixth generation plasma cluster whose claimed blowing power is 15 times stronger. The first type is equipped with water purifying filter and 4 way auto air swing that allows the wind to spread up, down, left and right. “This AC is suitable for homes with 900 watts of electricity, no need to add power anymore,” said Hendy Setiawan Product Assistant Manager of PT Sharp Electronics.

How efficient is it?

Low wattage AC is claimed to be able to save costs 30-50 percent compared to ordinary air conditioning. Here’s an example of the calculation. AC inverter (amount of cooling speed) 4275 kwh / day x 30 days x Rp500 / kwh = Rp63,113 per month. While non-inverter AC or regular AC, 8941 kwh / day x 30 days x Rp500 / kwh = Rp134,123 per month. There is a difference of Rp71,010 per month or 52 percent more cost-effective.

But according to Togar, in a year the amount of rupiah issued for the two types of AC is actually the same. AC inverters are more economical in operating costs, but the purchase price is more expensive than non-inverter air conditioners. For example, Sayonara Panas measuring ½ PK is priced at IDR 3.1 million – IDR 3.5 million / unit. “It’s comparable to the value added offered,” Hendry added.

In addition to the latest technology such as inverters, to know whether an AC is energy efficient or not, see its EER unit (energy efficiency). EER is a comparison between the cooling speed or BTU (British thermal units) and the electrical power used. For example, an AC BTU of 1 PK is 9040: 800 watts will produce EER 11.3. The higher the EER number means the smaller the energy used aka energy saving.

According to Christien, EER 11 is classified as energy efficient and efficient. He acknowledges that most consumers pay little attention to this matter. Usually the only question is the wattage. “Even though small watts of cooling are not necessarily maximum,” he said.

Therefore, if you are lazy to ask, pay attention to the product specifications listed in the brochure. See how many BTUs, sizes, features, and other advantages. For ½ PK sized air conditioners, for example, the BTU number that is supposed to be 5000 is often reduced to 4500 so it becomes inefficient. Other ways to choose AC are already popular and widely used because usually the specifications are better. By the way, if you are keen, check out how aircon installation is carried out.

 

Why home services business are so popular

There are many profitable businesses and one of those is definitely in home services. There are over thousands of companies in this space ranging from all sorts of home services such as cleaning services, plumbing services, painting services, electrical services, aircon services and really many more to mention.

Partly the reason is quite obvious as almost every home owners will require such services unless of course they know how to do it themselves. This is unlike cleaning your home or performing your laundry with the help of washing machine and clothes dryer, for home services, at times we just require a professional to do it. As we already know, there are so many homes in Singapore regardless in private or public housing. So you can expect a lot of people who would love to open up their business in this space and provide their services. The best part, such services are almost recurring means it’s expected that the home owners will require the services over and over again.

Due to this, you can see that this home services space is kind of over saturated with many businesses compete with one another in this cut throat business. In fact, it used to only be the traditional sort however today it’s getting even more digital. Traditional in the sense where people used to browse through newspaper, yellow pages, flyers to locate the services they require and calling them directly. However in this digital age, e-commerce has exploded in this space where you can now order your services directly from your computer or mobile devices. The choices is huge and it’s really the consumer world.

Some business owner choose to focus only on a single nice, example on cleaning services whereas some would prefer to offer all of it. The thing about e-commerce is there’s actually 2 kinds. One is where the company offering the services themselves are going digital where customer could place the order online, including online payment. The other is where a middleman opening up online marketplace connecting consumers and service providers. This is useful especially for service providers who are not really visible online. They would join such platform and list their services, especially those having high traffic in order to have their service offering known to others. In such model, these service providers may need to compromise a little. This means since they are not actually spending money to advertise themselves, but instead leveraging on online marketplace, they may have to compromise on the commission cut to pay the online marketplace.

Take for example aircon services, they may actually be charging $40 per unit for general aircon servicing however because they had to pay for the platform commission, they will only receive about 80% from the $40. There used to be a time where online marketplace is all about selling products such as shoes, gadgets, furniture, portable aircon, toys or even air purifier. As of 2019, there are more than 10 online marketplace websites in Singapore focusing on home services. Companies such as Kaodim, Flair, ServisHero, Plugbear, Ovvy, Zowedo and really many more are all competing in the same space.

This is the reason why SGTUB was launched slightly different., instead of being a typical online marketplace, ie a shopping website where people pay and order for service instead or product. To know more on, check out SGTUB.com

To close off, we would say consumer can expect to have even more choices in the years to come given that the home services business is very lucrative and it will explode soon.
