What is the role of water-cooled fan coils
1. Improve physical comfort
Fan coils can create suitable In the indoor air environment with human comfort, the fan coil unit provides fresh and clean air with suitable temperature by adjusting the air temperature and flow speed, and improves the use comfort of the central air conditioner. For places with high humidity and temperature requirements, the fan coil unit can play a good protective role.
2. Deodorization and dehumidification
When the central air conditioner is in use, the doors and windows are closed, and human respiration emits a large amount of carbon dioxide. Toxic and harmful gases produced by furniture and household waste will affect human health. The fan coil unit can eliminate harmful indoor gases by exhausting air, and at the same time, it can also remove the heat and humidity that are concentrated in the operation of indoor air conditioners.
Advantages and disadvantages of water-cooled fan coils
1. Advantages
Small size and high efficiency , low noise, low energy consumption; its body structure is exquisite and compact, strong and durable, the condensate water pan is integrally formed by molding process, without welding seams and welding points, and the thermal insulation materials that meet the fire protection specifications are integrally connected to the water pan.
2. Disadvantages
Since the unit of the water-cooled fan coil is generally installed indoors, it needs to cooperate effectively with construction and other types of work. The unit is relatively scattered, and its maintenance workload is large; the problem of fresh air must be solved; the static pressure of the fan is small, and high-performance filters cannot be used, which makes the indoor air cleanliness not high.
How to install a water-cooled fan coil
I. Installation method
The most important thing about a water-cooled fan coil is The common installation method is horizontal concealed installation, in addition to horizontal exposed installation, vertical concealed installation, vertical exposed installation, etc., the installation steps are not very different.
Second, installation steps
1. Installation of condensate drain pipe
The condensate drain pipe is an important part of the water-cooled fan coil unit Parts, when installing the fan coil unit, pay attention to the installation distance of the condensate water drain pipe, and set up the drain pipe at the place closest to the fan coil unit to shorten the drain distance and reduce the problem of dripping water from the water pipe. In addition, the diameter of the drain pipe drawn from the fan coil unit should be 20 size, not too much, and the size of the drain riser and the main pipe should be larger, so as to ensure smooth drainage.
2. Installation of water collecting tray
There is a danger of water leakage under the electric water valve between the fan coil unit and the cold and hot water pipes, so a water collecting tray should be established between them. Water Tray. During installation, connect the water collecting tray to the water collecting tray carried by the fan coil unit, so as to ensure that the condensed water from the valve can be discharged through this water collecting tray.
3. Installation of the air return port
The installation of the air return port of the fan coil unit is also a very important part. The filter screen must be installed at the air return port to ensure the cleanliness of the fan coil. Improve the efficiency of heat exchange. Otherwise, if the filter screen is not installed, the external dust will enter the fan coil through the return air outlet, which will affect the heat exchange efficiency of the fan coil unit.
III. Installation requirements
1. The supply and return heat pipes connected with the fan coil must adopt flexible connections. There are two ways of flexible connection, one is a special rubber flexible joint, each end of the joint is provided with a fingerprint joint, one end is connected with the ballistic, and the other end is connected with the fan coil unit. The other is an annealed pure copper tube, which is expanded into a speaker diamond shape with a tube expander at both ends and tightened with a nut.
2. A Y-type water filter can be installed on the intake and radiator pipes of the cold and hot radiator pipes connected to the fan coil unit to remove the machine impurities and sludge in the ballistics, so as to prevent the fan coil unit from being blocked .
3. The connection between the water-cooled fan coil and the cold and hot radiating pipes should be installed in the way of “send down to the last time” to solve the heat exchange function in a retrograde atmosphere. The position of the water-cooled fan coil unit must be accurate, and the nut is equipped with a cushion.
