VRF Air Conditioning, also known as central air conditioning systems, is a very useful type of air conditioning consisting of an outdoor unit group and multiple indoor units. These products attract great attention from air conditioning lovers thanks to their heating and cooling performance. Thanks to developing technology, VRF air conditioners are still being developed and continue to be used in many areas. It continues to attract great attention, especially from air conditioning lovers and architects. The rate of preference has increased due to its suitability to the architecture of the buildings. Both the investment costs and operating costs of VRF air conditioning systems are such that investors will be happy.

What is Fancoil?

Designed to meet the heat needs of your buildings, Fancoil is one of the main options you can choose when you need hot and cold air. Fan coil systems are water operated systems. Its basic working principle is to blow hot air with the help of fans if hot water enters, and cold air with the help of fans if cold water enters. Fan coils are very similar to air conditioners in terms of operation. Just like air conditioners, it can provide both cooling and heating. Fan coils should be preferred according to needs. Within the scope of needs, 2-pipe fancoil systems or 4-pipe fancoil systems can be preferred. While a 2-pipe system works in heating or cooling mode, 4-pipe systems can operate in both heating and cooling mode.

Differences between Fancoils and VRF Air Conditioners

Innovations in the air conditioning sector have gained momentum recently. During the acceleration process, most people had difficulty in following these trends. Within the scope of this article, we will make a useful comparison between fan coil systems and systems known as variable refrigerant flow air conditioning systems.

The differences of the two systems are as follows.

Fancoil is not an air conditioning system, it only works using a single fancoil unit. This system works with fans blowing hot air when hot water comes to the unit and fans blowing cold air when cold water comes to the unit. If the water coming into the system is cold, all devices are expected to blow cold air; if it is hot, all devices are expected to blow hot air.

VRF System, on the other hand, can blow air with different temperature values in different locations. It does this by using multiple indoor units. Generally, several such indoor units can be found throughout your home. This allows you to vary the volume of refrigerant sent to a specific indoor unit manually or even automatically by programming your thermostat. As a result, you can adjust the exact amount of cooling each different area of your home receives. This allows you to maximize cooling power while avoiding spending more on heating unused parts of your home.

In the VRF system, the outdoor units are generally located in the external part of the space, while in the Fancoil systems, the chiller or boiler serves as the external unit in the mechanical rooms. Therefore, while mechanical room installation is required for fan coil systems, such a need is not required for VRF systems.

The fluids circulating in the system also differ. While the fancoil system provides heating and cooling with water, VRF air conditioning systems provide heating and cooling using refrigerant gas.

The advantages of VRF System compared to Fancoil System are as follows;

  • It can operate in different modes in different locations without the need for a mechanical room.
  • Unlike 2-pipe fancoil systems, they can be used for both heating and cooling.
  • It is easier to install in old buildings than fan coil devices.
  • Temperature control features and temperature sensitivity are good.

The disadvantages of the VRF System compared to the Fancoil System are as follows;

  • They cannot be used in applications where 100 percent fresh air is required.
  • Determined standards are taken into account in the selection of refrigerant.
  • In case of malfunction, it is possible to cut off the water coming to the fan coils and disassemble and assemble the system.
  • In VRF systems, the gas in the system must first be drained, the fault repaired and the gas charged again.
