The fan coil is a type of air conditioning system that, like any other air conditioning system, is responsible for temperature control, humidity control, air freshening and air circulation. This device includes a heat exchanger and a fan, but the main source of heat and cold is not available in this device. In fact, for proper use of the air conditioning system with a fan coil, a water source such as a boiler or package must be provided. This boiler or package is the power supply for the fan coil and water enters the fan coil through the pumps. In this way, the fan coil can produce both cold and heat. The fan coil is controlled by a thermostat or on / off switch. The fan coil has two major advantages due to its simple structure. One is that it can be an economically viable option for many applications in different locations, and the second is that this structure allows the fan coil to be installed at different angles and locations of the structure. As we see the walls, floor, ceiling and other types of fan coils.
The ground fan is one of the types of surface fan coils that are placed vertically and standing on the ground and has many fans. This fan coil can be easily installed and moved. Since the ground fan coil is quite clear, great care is taken in designing its appearance. In fact, the ground fan is part of the overall appearance of the space and is an element of its decoration. We have seen many examples of them in a variety of commercial, office, educational and even residential spaces. This type of fan coil has developed a lot over time. In fact, changing its appearance is one of the developments that has made the ground fan coil suitable for use in any place and time.
How ground coils work
The operation of the ground fan coil, which, like other fan coils, includes a fan and coil, is such that suction of air from the front or back and blowing of air from above takes place. This cycle changes the air inside the environment and activates the airflow. This fan coil has a range of different capacities and the shape and angle of the air blower can be adjusted in them. Examples of angled fan coil valves are called sloping ground fan coils.
Ground fan coils are defined in two types: two-pipe and four-pipe. In two-pipe fan coils, each of these two pipes is dedicated to hot and cold water flow, so in this model of ground fan coils, the device has to work either as heating or cooling, the possibility of operation for the device They do not exist in both models at the same time. But four-pipe fan coils have one cold coil and one hot coil, and for this reason, they can work both cooling and heating.
If we remember that cold air is located in the lower parts of an environment and hot air is located in the upper parts due to lightness, we can understand the reason for the location of the fan coil inlet and outlet valves.
In cold seasons, the inlet valve, which is close to the ground, draws cold air into the fan coil. This air is returned to the room after heating through the outlet valve located above the ground fan coil.
In hot seasons, the same cold air enters the fan coil through the intake vents, becomes colder again, and then enters the space through the outlet vents to cool the environment.

What are the disadvantages of a ground fan coil?
Since we said that the ground fan coil is physically placed on the ground standing up, so it takes up a lot of space. Of course, with the advancement of manufacturing technologies, the dimensions of the new fan coils have changed and many of them are completely narrower than the old models and occupy less volume, but this can be problematic in small environments. Be.
Another disadvantage of fan coils is the noise it produces. Since this fan coil is physically on the ground, its noise can be fully felt, although it varies depending on each fan coil and can be controlled in different ways, installation methods and using different blowers. So as not to be annoying, but in any case, the amount of sound produced does not reach zero.
What are the advantages of a ground fan coil?
One of the best advantages of a ground fan is its reasonable price. The simple structure of a ground fan coil brings together the good benefits of a fan coil in a medium but affordable set. Also, due to the way the fan is installed, the installation cost is relatively lower.
Due to the surface of the ground fan coils, access to the fan coil is easy. This leads to both the ease of installation and the ease of repair in case of failure and replacement of components such as filters if necessary.
However, the general advantages of fan coils make many people want to use fan coils for their space, but when it is not possible for the building to be split from the ceiling or wall so that the fan coil inside you To work, a ground fan coil can be used. This fan coil is placed on the ground and in this way, the environment enjoys the facilities and benefits of the fan coil and there is no need to change and renovate the building. In this way, the use of a ground fan in any environment is without problems and possible.
As mentioned, the ground fan coil is considered as a factor in the decoration, this issue has caused the manufacturers to give the fan coil a variety of appearance, colours and designs. The variety of appearance and colour variations available for ground fan coils is naturally welcomed by many people, thus this fan has become very popular.
The fan coil system is not an integrated system, and any room and space that has its own fan coil can easily adjust the intensity of its work to be different from other rooms. These settings only refer to the power of the fan coil, not how it works.
What problems might arise by installing a ground fan?
One of the main drawbacks of ground fan coils is the noise generated when working. Of course, this depends on various factors such as the installation and structure of the fan coil itself, such as the type of motor and blower, but in any case, this sound is always present with different intensity and volume.
Since ground fan coils are installed individually in each room and space, when any of these fan coils break down, it is necessary to replace the components inside each of them, especially the ground fan whose fan is one of the main components of sound production inside. If the sound is produced, the fan should be replaced immediately so as not to be annoying.
Another common drawback of ground coil fans that does not leave consumers free is the inability to control the temperature or how the device heats and cools. In fact, in two-pipe fan coils, all devices have to operate either cooling or heating. This air conditioning system is not suitable for places such as hotels or large commercial and residential buildings with high units that each person may need one type of system depending on their taste, so the two-pipe system for ground fans is limited. brings.
