Fan coil installation specification. Construction specifications.

Support and hanger installation: 1. The fan coil unit should be equipped with independent supports and hangers for fixing.
2. Determine the rooting position of the derrick according to the construction drawing, and expansion bolts are generally used for rooting.
3. According to the different models and weights of the fan coil units, select the corresponding specifications of the boom.
4. The installation of vibration damping hanger shall meet the design requirements.

Fan coil installation: 1. The installation height and position of the horizontal fan coil should be correct. The connection between the boom and the coil should be fastened and leveled with double nuts. A 3mm thick rubber pad should be added on the nut.
2. The lifting coil should be tilted to the water tray drain.
3. For hidden horizontal fan coil units, the inspection door should be kept on the ceiling to facilitate unit maintenance.
4. The installation of the vertical fan coil should be firm, and the position and height should be correct.

Connecting pipes: 1. The air duct, return air bellows and air outlet should be tightly and firmly connected with the fan coil unit.
Fan coil 2. The connection between the fan coil and the cooling and heating medium pipeline shall be carried out after the pipeline system is flushed and discharged, and the circulation trial operation shall be carried out for more than 2h after the water quality is qualified, so as to prevent foreign matter from blocking the surface cooler.
3. The inlet and outlet pipe joints and drain pipe joints of the fan coil must not leak, and the inlet and outlet pipes must be insulated to prevent condensation.
4. The connection between the fan coil and the pipeline should be a hose or copper pipe, and its pressure resistance should be greater than or equal to 1, 5 times the working pressure, the hose connection should be firm, and there should be no distortion and pipe collapse.
5. The hose is used to connect the condensate pipe. The length of the hose is generally not more than 300mm. The hose should use a transparent hose and be fixed with a hose clamp to prevent leakage. The condensate should flow smoothly to the designated position, and the water pan should be free of water.

The fan coil device should be installed in accordance with the standard method. Only in this way can the normal operation of the fan coil be guaranteed and the service life of the fan coil be prolonged. In the above article, the editor introduced in detail the matters needing attention and operation specifications when installing the fan coil device. As long as everyone strictly abides by the specifications in the process of operating the fan coil, they can ensure the safe operation of their fan coil unit, today's brief introduction on fan coil installation is over, I hope it will be helpful to friends.
The electric two-way valve used on the fan coil should be installed on the water supply pipe or the return pipe.
The electric two-way valve used on the fan coil is installed on the return pipe, that is, e. The outlet pipe, the inlet pipe (water supply pipe) is equipped with a Y-type filter, which can adjust the flow of the outlet to meet the required temperature and humidity. Prevent the gas pan from idling due to lack of water.
The fan coil is the ideal end product of the central air conditioner. It is composed of a heat exchanger, a water pipe, a filter, a fan, a water connection plate, an exhaust valve, a bracket, etc. Its working principle is to continuously circulate the air in the room where the unit is located, so that the air is cooled (heated) after passing through the cold water (hot water) coil to keep the room temperature constant.
Usually, fresh air is sent to the room after being processed by the fresh air unit to meet the demand for fresh air volume in the air-conditioned room.
The electric two-way valve used on the fan coil is installed on the return pipe, that is, e. The outlet pipe, the inlet pipe (water supply pipe) is equipped with a Y-type filter, which can adjust the flow of the outlet to meet the required temperature And humidity to prevent the gas pan from idling due to lack of water.
When the valve is not working, it is in a normally closed state. When it needs to work, the room temperature controller provides an open signal to open the electric two-way valve for operation. When the valve is opened, cold or hot water enters the fan coil to provide The room provides cold or heat. When the room temperature reaches the set value of the room temperature controller, the room temperature controller closes the electric two-way valve, the return spring closes the valve, and cuts off the water flow into the fan coil.
By closing and opening the valve, the room temperature is always kept within the temperature range set by the room thermostat.
The drive can provide high and low voltage models, flexible application, AC hysteresis synchronous motor, quiet operation, constant torque, flat design, in action when taking up less external space, can be installed close to the wall, the drive device can be installed after the valve body is installed.
