If you need to purchase an efficient device for cooling and heating air, fan coil units are the best option. Today we will analyze what a fan coil is and how it works.
This equipment allows you to create comfortable living conditions, despite the time of year and the area of the room. Today, the market offers a wide range of fan coil units, which differ in types of placement, and have unique features. The fan coil unit is energy-efficient equipment, so the purchase costs will be compensated over time by its efficiency.
Fan coil unit is an efficient equipment that is used to cool and heat a room to a predetermined temperature. The cold and heat generation for the fan coil unit is carried out using:
The fan coil unit consists of:
The movement in the fan coil unit is carried out with the help of a liquid, which is a heat carrier. It can be cold or hot depending on the purpose - cooling / heating.
We have already analyzed what a fan coil unit is and how it works. Let's move on to its types and systems with which it is used.
First of all, the fan coil unit is a versatile device that has a unique design and is easy to use. Today, the market provides a wide selection of fan coil units, which differ in the placement of the fan coil unit in the room.
Considering various factors, such as location, installation or interior design features, the appropriate type of fan coil units is selected:
A cassette fan coil is a device that is designed to cool / heat air. Thanks to the device, you can achieve a uniform temperature in rooms with a large area. The advantages are a low noise level and significant energy efficiency.
Generally, cassette fan coil units are suitable for industrial and administrative buildings. Installation of equipment does not harm the interior, as it is installed into the suspended ceilings. The advantage is that only the panel for air supply and exhaust will be visible on the ceiling.
The ducted fan coil unit is also in great demand, like the cassette fan coil unit. Generally, these units are used in residential buildings.
The advantages of ducted fan coil units are as follows:
Wall-mounted fan coil units are the most popular type of equipment. They have the following benefits:
Floor-mounted fan coil units are placed under the window to limit the flow of cold air in winter and heat in summer. The disadvantage of such fan coil units is the space occupied in the room.
There are two types of fan coil unit connection:
The principle of operation of the fan coil unit is quite simple:
Fan coil units have the following advantages:
The disadvantage of the equipment is its noise characteristics. However, this problem is also solvable. By increasing the size of the fan coil unit, you can choose acceptable dB and achieve minimal noise level.
To choose the right fan coil unit, it is necessary to consider the amount of heat input in the house. In addition, to avoid high noise characteristics, it is necessary to pay attention to the standard size of the equipment: the higher it is, the quieter the fan coil will work.
For example: we will install a fan coil unit of the 3rd standard size in the room. To provide full cooling/heating, it must work at the 5th speed. In this case, the noise level will reach 65 dB. Of course, such high dB level is unacceptable.
To solve this problem, it is necessary to increase the fan coil area by only 30%, and this will save users from discomfort. Therefore, choosing, for example, the 5th size, will enable the fan coil unit to operate at the 1st or 2nd speed at 25 dB.
As already mentioned, the fan coil unit only works together with a heat pump or chiller. Let's analyze these systems in more detail.
If you need to install a fan coil air conditioning system in industrial or administrative buildings, an excellent solution will be to purchase a chiller-fan coil system.
A chiller is a unit that contributes to the cooling / heating of a liquid, which is located on the roofs of buildings.
The principle of operation of such a system is as follows: after cooling / heating of the liquid in the chiller, it is supplied to the internal heat exchanger (fan coil unit). The system then supplies cold or warm air into the room, depending on the task.
A heat pump is an efficient and cost-effective device that is used for cooling and heating rooms.
Types of heat pumps:
Depending on the purpose of use, you can choose the optimal additional unit.
For industrial or administrative buildings, it is better to use a chiller-fan coil system, and for residential premises, a heat pump will be the right choice.
To sum it up: fan coil units are ideal equipment for maintaining the desired microclimate in both commercial and residential premises.
What a fan coil unit is and how it works can be found in more detail above.
The fan coil unit and the air conditioner have different heat carrier. Freon is used as a working fluid in an air conditioner, and water is used in a fan coil unit.
Its principle of operation consists of several processes:
Depending on the type of building, the perfectly suitable type of fan coil units can be selected. If you need to install equipment in industrial or administrative buildings, the right solution will be to use a cassette type. If the room is intended for housing, ducted fan coil units will be the best option.
