General introduction of fan coils
A fan coil is one of the most common devices in air conditioning systems, which is responsible for air conditioning in general. This air conditioner includes temperature regulation, humidity regulation, air circulation and air disinfection, which the fan coil can only regulate its temperature and circulation and is not able to perform the other two tasks. Of course, the fan coil can generate heat in the cold season and, conversely, provide heat in the hot season. In this way, the fan coil is considered as a heat exchanger that enters the desired space, cooled or heated, through hot and cold water through valves.
The structure of the fan coil is as follows: it consists of a number of copper coils, water inlet and outlet pipes along with a fan as a blower. Also, the thermostat, motor and outlet valve are other internal components of the fan coil. About how the fan coil works It can be said that the coils inside the fan coil contain hot or cold water, the water inside of which is supplied through a package or boiler or chiller. The air entering the fan coil passes through these coils, the temperature changes and then exits the fan coil to enter the desired environment through the outlet valves.
What is a cassette fan coil unit?
Cassette fan coil with the original name of Cassette is one of the types of fan coils that are installed in the work and only its valve is in front of people. The cassette fan coil is installed completely inside the ceiling and does not attract attention in this regard and gives a concise and clean appearance. In this way, the appearance created by the fan coil is suitable for places that care about the final effect. Of course, there is no limit to the use of cassette fan coils, and all places with any type of use, such as offices, shopping malls, homes and other places can use the cassette fan coil for air conditioning service. Since the defect is located inside the roof and above the heads of passers-by and people, as a result, the direction of the air movement of the fan coils is exactly from top to bottom.
How many types of cassette fan coils are there?
There are three types of shortcomings for fan coils that distinguish them (in part) both in terms of performance and in terms of physical appearance. One is a single-sided cassette fan, the other is a four-sided cassette fan, and the other is a 360-degree circular fan coil. One-sided shortcomings, as the name implies, scatter the air in one direction. In the same way, it is usually placed in the corner of the room ceiling and next to the wall, as well as near the door or window to be exposed to airflow. The one-way fault has a coil.
The four-way fan coil has four valves on the four main sides of the top, bottom, left and right of the device and allows air to enter the space from all four. For this reason, this type of fan coil is usually installed in the middle and middle of the roof, which can work in all directions. In contrast to the previous one-way, this model accommodates two types of coils.
The third shape of the fan coil, which is 360 degrees circular, has the appearance of a circle. In such a way that its valve is in the shape of a circle and in this form, it expels air and there is no longer a specific geographical direction.
Advantages and disadvantages of cassette fan coils
Do not occupy space
One of the main advantages of fan coils is their lack of space and the way they are installed. Deficiencies are small and even account for false ceilings. This feature is placed in front of the existing restrictions for installing heavy and bulky devices in prefabricated and false facilities and structures. This advantage also provides the use of this type of fan coils in rooms and spaces with short ceilings, because the fan coil has virtually no height.
High capacity and high work efficiency
Delicate and graceful appearance
Built-in internal pump
Due to their function, some water accumulates inside the fan coils, which is inevitable. This water settles on the pipes in the form of dew due to distillation and their accumulation is considered dangerous and is harmful to both the health of people who are in contact with the fan coil air and the health of the device itself. Therefore, this water must be removed from the fan coil. Drain trays and pipes are used to drain this water to direct the water to the desired point for draining. There is a defect in the pump itself that directs the water to the direction it is intended to drain.
Ease of cleaning and maintenance of the fan coil
Since only the vent part is outside the ceiling, only this part needs to be cleaned and this can be done with a long auxiliary tool that reaches the ceiling. This way, it is cheap and easy to maintain and clean.
One of the disadvantages of cassette fan coils is the vulnerability of their panel!
One of the negative points about the fan coil is its shortcomings in the valve and its control panel. Since this panel is the most important part of the fan coil and yet it is made of plastic, it needs high maintenance and care. This care is very important both during the initial installation of the fan coil and to some extent in its overall cleaning and maintenance. When installing the fan coil, the defect should not hit the plastic panel hard.
Cassette similarities with other fans
One of the fundamental similarities of shortcomings with other fans is their performance. In fact, the disadvantage is only the special appearance of the fan coil and only has a different appearance from other fan coils.
Cassette difference from other fans
One of the main differences between faulty fan coils is that they are built-in and placed inside the ceiling. These fan coils are located exactly inside the ceiling and do not occupy any volume of the interior space of the room. Also, their airflow is from top to bottom and not face to face. Another difference is the lack of fan coils trying to reduce noise pollution in them to a minimum.
