If you are a frequent user of air-conditioner system, you would know how air-conditioner works in Singapore. So basically, you will set your desired temperature and it will cool down your room according to that temperature. When your room starts to warm up again, the cycles will repeat to cool it down. This is pretty straightforward and everyone would understand it easily. This basic method of the cooling operation is proven and tested to control the temperature in a room or house. Similar to other applications, we have seen new innovation in the air-conditioning system over the years.
If you are researching for the type of air-conditioning system that best suits your cooling needs in Singapore, you might come across new technologies and development of the VRV and VRF system. The advantages related to this innovation are definitely attractive, as they are able to improve the cooling comfort at greater efficiency and operating cost.
With the wide range of different air-conditioner system in the market, it is easy to get confused between one another, especially the differences between VRV and VRF air-conditioning system in Singapore. We will go through some of the differences between these air-conditioning.
Both the VRV and VRF air-conditioner system operate similarly where the cooling framework and operations are similar. Since both are similar, you may wonder why both are called differently. This is due to the term VRV is owned by Daikin through copyright. Daikin’s VRV (Variable Refrigerant Volume) systems was one of the pioneers in the new development of the air-conditioning system which first emerged in the market in 1982.
The term VRF is commonly used for similar system which are found in other air-conditioner brands such as Mitsubishi Electric’s VRF. With the rising development of the air-conditioning system among other brands, the use of VRF (Variable Refrigerant Flow) increase and gets more popular as compared to VRV.
As mentioned above, both the VRV and VRF systems are basically similar in terms of operation. So you might wonder how these affect you. To get into details of understanding the system, it is good to delve into some of the functions and operations of it. It is one of the sophisticated air-conditioning system with new developments in its technological advancement. We will go through some of the framework and operations of the air-conditioner system.
With components that are not found in the common air-conditioner systems, the framework of the system allows cooling operation at reduced energy consumption, which are efficient during operations. In VRV and VRF air-conditioner, refrigerant plays an important role where it is the main coolant material that are used in the system. This is different from the chilled water systems where the responsibility of refrigerant is to cool down the water circulating throughout the chilled water system.
With the new innovation, it is capable of adapting to cooling needs and allows expansion depending on the projects which could expand as times goes by. Also, with the efficiency of the cooling performance, it is able to handle various units which are connected in the same air-conditioning loop. This will ensure efficiency could be maximised and ease of control.
The rationale behind the framework of the VRV and VRF air-conditioner are usually depends on the manufacturers, which they own the full rights of their technological innovation. It is no surprise that it is similar to other air-conditioning systems where users will set the input such as the desired temperature. However, there is an additional consideration of the surrounding temperature, and through these data, it will be able to provide the optimal cooling comfort for the area. This will also ensure the energy efficiency is maximised and help to reduce the energy consumption during operation.
Within both systems, the ability to adapt to the surrounding temperature is one of the drivers that result in greater efficiency as compared to other types of air-conditioner system, which tends to consume higher power consumption.
During the start, the unit will be on operations standby condition, where the units are not turned on yet. Once the unit is switched on, it will activate the system where the VRV or VRF system will starts running.
The VRF or VRV air-conditioning units will then take into consideration of the outdoor surrounding temperature as well as the room temperature. These will help to determine the level of performance in the VRV or VRF system to achieve the desired temperature.
This procedure will be repeated when another unit is being switched on in the home or office. With the additional units operating, it will be running optimally depending on the temperature settings to achieve optimal level of energy efficiency.
Through these operations, users are able to adjust the settings in the air-conditioning system to achieve their ideal cooling comfort, including fan speed, temperature and operation mode. These settings are limited in centralised air-conditioning system. Hence, similar to the common cooling units seen in Singapore, where in the VRV or VRF system, you could also easily adjust these settings in each individual room.
1. The temperature of the room or area will be detected and is one of the factors that would achieve greater efficiency in the cooling system. These air-conditioners that are equipped with this would be able to achieve desired cooling temperature at an optimal level and providing cooling environment.
2. It is useful in an environment where there are changes in the temperature or weather. In Singapore, the hot weather could instantly change to heavy rain, which could result in the change in temperature. Thus, the VRV and VRF air-conditioning are helpful where it potentially eliminates the manual settings as it is equipped with controls to adjust the temperatures to provide cooling comfort.
3. Since the performance level are determined by the outdoor environment, the operations of the system will result in greater efficiency and cost benefits in the long-run with its adaptability.
4. The precise zone control enables full control of the operations where you could save money and energy cooling rooms which are not being utilized. Thus, the technologies in the automatic features and operation controls enable lower power consumption and users are able to save on the power bills in the long-run.
5. Easy to expand with the VRV or VRF modular design. It is able to expand user cooling needs if the building or projects require additional cooling requirements over time.
With the range of benefits and its energy and cooling efficiency, the VRV and VRF systems are widely installed in commercial and industrial premises in Singapore. It is also often installed in large houses, including landed premises. There are many brands including Daikin and Mitsubishi that offers such VRV and VRF system in Singapore.
Similar to any other air-conditioning, regular aircon servicing for VRV and VRF air-conditioning is required to ensure optimal performance. If you happen to experience some problems, to repair VRV and VRF air-conditioner system, it requires well-trained and skilled technicians by experienced air-conditioning repair company in Singapore.
