In April 2023, the Consumer Council tested 13 types of window air-conditioners, commonly known as "1.5HP", including 10 inverter air-conditioners and 3 fixed-frequency air-conditioners. The results showed that the energy efficiency of the samples differed by up to 37.1%. Although the four models were all awarded the Level 1 Energy Label, the energy efficiency of the four models varied by up to 12.4%. In addition, the cooling capacity of the 8 models was lower than the claimed value, with a maximum of 5.7% lower.

Types of air conditioners

Window air conditioners

This type of air conditioner is usually installed on a window frame or a special air conditioner stand with a metal bracket. Some models are even equipped with a remote control and time button.



Split Air-Conditioner

This type of air conditioner is composed of an indoor unit and an outdoor unit. Because the compressor is installed outdoors, it is quieter than the window type when used. Split air conditioners are generally equipped with a remote control and time button.



However, some split-type air conditioners on the market are designed as "window split type", and most of them are called "slim type" or "slim series" split units. Although the appearance of the machine is not much different from the general split machine, it can be installed in most window positions, is smaller in size, and is easier to install.

Inverter air conditioners

This air conditioner has the same window and split designs as the traditional air conditioners (cannot heating), and the more common as split type. The difference between a inverter air conditioner and a general air conditioner is that the snow in a general air conditioner can only flow in one direction to take the indoor heat out of the room; while the snow in a inverter air conditioner can reverse the flow direction. The air conditioner can provide cooling in the summer, bring outdoor heat into the room in the winter, and blow out warm air at the outlet location.


How to choose an air conditioner? You can consider the points listed below:

Fixed-frequency VS inverter air conditioners

What is fixed-frequency air conditioners?

Fixed frequency air conditioners always maintain a certain output power. When the room reaches a predetermined temperature, it stops running and does not restart until the air conditioner's temperature sensor senses that the temperature in the root room is higher than the set temperature. By adjusting the room temperature by repeating pauses and restarts from time to time, the process causes the room to fluctuate greatly and consumes more power. However, fixed-frequency air conditioners are cheaper.

What is inverter air conditioners?

Inverter air conditioners automatically adjust the output power according to changes in room temperature. It uses electronics to adjust the operating frequency. Running at a high speed at the beginning of the start-up, the temperature of the room can reach the set cooling level faster. When the temperature difference in the room is reduced, it is switched to slow operation to maintain a constant temperature to make users feel comfortable. Inverter air conditioners can make room temperature fluctuations less and consume less electricity. However, inverter air conditioners are more expensive than others.

Air conditioner shopping guide:

1. Power unit comparison table

"Horsepower"(HP) is the unit of power of an air-conditioner. The large number of horsepower of the air-conditioner also means that it consumes a lot of electricity and has a high cooling capacity.
In general, the larger the number of horsepower, the larger the cooling area.

Horsepower Refrigeration area
(square meters)
1 HP 10 - 20
1.5 HP 16 - 28
2 HP 23 - 30
3 HP 33 - 40

Although the larger the number of air-conditioners, the cooler they are when to use, they also bring huge power consumption. Therefore, it is enough to choose the right one.

2. Refrigeration capacity

The cooling capacity of an air-conditioner is very important. The refrigerating capacity of an air-conditioner is generally expressed in terms of cooling capacity. The unit is usually kilowatts (kW) or British thermal units per hour (BTU/h). A high value means a high refrigerating capacity. The choice of appropriaterefrigerating capacity depends on different circumstances, such as the size of the room, the location of the room, the number of residents, etc.
However, if the cooling capacity of the air-conditioner is too high, the compressor in the air-conditioner will automatically stop and restart frequently. Since the current of the compressor is higher than that of normal operation, the power consumption is higher. Therefore, consumers should consider different factors when making a choice.

Room size




When buying an air-conditioner, remember to know the size of the room so that the indoor temperature is too low or too high when using it. When you know the volume of the room, you can refer to the cooling capacity of different air conditioners to choose.




3. Placement

In addition to room size, there are other relevant factors that should be paid more attention to. For example, whether the face of the room is constantly exposed to sunlight. In addition, if you live on a higher floor, if you live on a higher floor, it means that the direct sunlight on the room makes the indoor temperature high, and the load on the air conditioner is also greater. In addition, in some houses, it is forbidden to extend the body of the air-conditioner out of the street, so that the body of the air-conditioner should be moved indoors, so that the heat dissipation position next to the air-conditioner will be sealed. This practice affects the heat dissipation of the air conditioner, reduces its efficiency, wastes electricity and even affects the cooling effect, and more seriously, reduces its lifespan.

4:Energy efficiency, power saving

The cooling energy efficiency of an air-conditioner is generally expressed in terms of Energy Efficiency Ratio (EER). Energy efficiency ratio refers to the ratio of cooling capacity to electricity consumption, i.e. how much cooling capacity can be converted into each unit of electricity consumption.

A higher value for the energy efficiency ratio indicates that the cooling is more energy efficient and more energy efficient.

In addition, if you want the air-conditioner to be more power-efficient, you can use it with a circulating fan. However, there is knowledge in the position of the circulating fan, and it is more energy-saving to put it in the right position.

5. Noise




The air conditioner will make a certain sound when it is running. If the noise generated during operation is too loud, it will affect the quality of life. Therefore, consumers can do research before making a purchase. Take a look at the opinions of other users of your favourite air-conditioner style, and then compare the different options to choose the best one.

6. Function

A good air-conditioner should have features that make your life healthier and more comfortable. Conventional air-conditioners are equipped with a basic filter to keep out particles and dust in the outdoor air. With the development of technology, today's air conditioners even have built-in UV air filtration systems, anti-oxidant filters and other functions.

In addition, you can also choose to buy an air-conditioner with a function to keep the room hydrated. The use of the air conditioner will reduce the amount of water in the room, and if you use the air conditioner, it will reduce the dryness of your skin, throat, and eyes when you turn on the air conditioner. It is very important for consumers who often use air-conditioners at night.

Installation



When purchasing an air-conditioner, pay attention to whether the price includes the basic installation, and also pay attention to the items included in the basic installation of different brands and retailers. Therefore, you should check the relevant information and details before purchasing. If you are unsure about the installation cost, you can ask the retailer if they can come to your home to see the situation and quote the price, but there may be a fee for this service.

In addition, consumers should be careful not to install the air-conditioner in a place where direct sunlight is exposed to the technician during installation. To prevent water dripping from the air-conditioner, add an overflow hose to the chassis of the air-conditioner to drain the excess condensate to a suitable place. Moreover, the installation must be secure, which can cause noise at least and may be dangerous when strong winds or other unpredictable shocks blow and the air-conditioner may fall out of its original position or even fall into the street.

Save electricity

When purchasing for an air-conditioner, remember to pay attention to the energy label on it. There are five levels of energy efficiency, with Level 1 being the highest, i.e. the most energy-efficient and cost-saving, and Level 5 being the lowest. Therefore, consumers should refer to the annual electricity consumption and cooling capacity listed on the energy label when purchasing, compare different models of air-conditioners, and choose the most energy-efficient one.

According to the EMSA report, when purchasing window air-conditioners, choosing energy efficiency level 1 will save 25% of energy compared to level 5. Choosing a split-type air-conditioner can save 61% of energy compared to Level 5 for energy efficiency.

7. Maintenance

With good maintenance services, you can make your air-conditioner last longer. Consumers should check the warranty period and items provided by the manufacturer at the time of purchase. Most new machines have a warranty period ranging from 1 to 3 years. The warranty period of the compressor in the machine is longer than that of the whole machine, generally 5 years. The renewal premium ranges from $510 to $1500. Usually during the warranty period, you can get free on-site inspections in urban areas, but if you live in remote areas, you will be charged a fee ranging from $130 to $420.

In addition, users should always pay attention to whether the air-conditioner is stable and regularly consult an experienced technician to check whether the bracket structure and screws are firm and safe. Remember to clean the dust filter, inlet and outlet regularly to avoid obstructed airflow and affect performance.

Consumer Council’s 8 Tips for Saving Electricity Bills of Air Conditioners

  1. Avoid installing the air conditioner in a place exposed to direct sunlight
  2. Do not block the air inlet and outlet of the air conditioner
  3. In summer, you can close the curtains to prevent direct sunlight from shining indoors, and close doors and windows as much as possible to maintain indoor temperature.
  4. The power consumption of the fan is much lower than that of the air conditioner. By turning on the air conditioner and the electric fan at the same time, the air conditioner is blown closer to the user, and the temperature setting of the air conditioner can be increased to save electricity.
  5. If the air conditioner is equipped with a time switch, you can preset the shutdown time to avoid using it for too long or forgetting to turn it off.
  6. When the weather gets cooler, use a fan if possible
  7. During summer, it is recommended to clean the dust filter, air inlet and air outlet about once every two weeks.
  8. Using the heating function of the air conditioner in winter is far more energy-saving than using a heater or heater.

    Air conditioners are always an important household appliance that is indispensable in summer. Therefore, you should pay more attention to different considerations when purchasing, and look for information on different models online or in electrical appliance stores, so as to make comparisons and choose the air conditioner that best suits you!
