When you have to refill the aircon, you must know the different types of aircon refrigerants in Singapore. Refrigerants are substances that absorb heat from the indoor air and release it outside. Therefore, they are the most critical component of the cooling process.
Over the years, different types of refrigerants have been developed. All these refrigerants have their characteristics and offer certain advantages. This article explains the different types of aircon refrigerators so that the choice becomes easier for you.
How Many Types of Refrigerants Are There in Singapore?
Refrigerants play a crucial role in the functioning of aircon systems. They undergo a cycle of evaporation and condensation to absorb heat from your home and release it outdoors. The aircon refrigerant type used in an aircon affects its efficiency and overall performance. There are different types of aircon refrigerants available in the Singaporean market.
LS Aircon Servicing Singapore offers aircon installation, aircon repair, and aircon gas top-up services, along with a comprehensive guide on different types of air conditioner refrigerants. Let’s explore their guide to know the types of AC refrigerants in Singapore.
1. R-22 (HCFC-22)
R-22, also known as HCFC-22, was once the most commonly used refrigerant in air conditioners worldwide. It is an effective coolant that served cooling systems for a long time. However, it has a significant environmental drawback: it contributes to ozone layer depletion and global warming.
Due to these environmental concerns, the production and use R-22 have been gradually reduced. While many older aircon units in Singapore still use R-22, newer models have changed to more environmentally friendly alternatives.
2. R-410A
R-410A, also known as Puron, is among Singapore’s popular refrigerants used in modern aircon systems. It was introduced as a replacement for R-22 and is widely used for its efficiency and lower environmental impact.
R-410A does not affect the ozone layer and has better energy efficiency. This can also help you reduce your electricity bills. Moreover, aircon systems are usually designed for improved performance and reliability. If you plan to buy a new aircon system, consider this refrigerant.
3. R-32
R-32 is a relatively new refrigerant popular in Singapore due to its perfect energy efficiency and reduced environmental impact. R-32 has a lower global warming potential (GWP) compared to R-410A. Therefore, it is more environmentally friendly than the R-410A refrigerant.
It also requires less refrigerant to get the same cooling effect, which can make aircon systems more efficient and cost-effective. Many of the latest aircon systems in Singapore are now using R-32.
4. R-134a
R-134a is another refrigerant used in some aircon systems. It is particularly popular in vehicles and smaller aircon units. It has been a popular choice due to its effectiveness and eco-friendly nature. However, R-134a has a higher global warming potential than newer alternatives like R-32. As a result, it could not gain as much popularity as its counterparts are getting. Therefore, it is losing its grip on the market.
5. Natural Refrigerants
In recent years, there has been a growing interest in natural refrigerants, such as propane (R-290) and ammonia (R-717), which have the least environmental impact. These refrigerants have low global warming potential and do not contribute to ozone depletion. However, they have issues, such as flammability and toxicity, which limit their widespread use in residential aircon systems.
Despite these challenges, researchers are exploring these alternatives to reduce the environmental impact of cooling systems. Natural refrigerants are increasingly explored as eco-friendly alternatives, particularly in commercial and industrial applications.
Conclusion
When you have to select an air conditioner in Singapore, it’s essential to review the types of aircon refrigerants to make informed decisions. The right choice can impact your comfort and also the environment.
R-410A and R-32 are currently the most popular options for residential air conditioning systems due to their balance of efficiency and lower environmental impact. However, as technology advances, we may see natural refrigerants taking their place.
