Fan coils are ideal end products for central air conditioning. Fan coils are widely used in hotels, office buildings, hospitals, commercial and residential, and scientific research institutions. It is understood that there are many types of fan coils to meet the design choices for different occasions, horizontal concealed (with return air box) fan coils, horizontal surface mounted fan coils, vertical concealed fan coils, vertical Surface mounted fan coil, card type two-outlet fan coil, card-type four-outlet fan coil, wall-mounted fan coil and so on.
The selection of fan coil is a key issue. It is a common practice in the design of air-conditioning systems to select fan coils according to the maximum cooling load of air-conditioned rooms. Its purpose is to ensure the room temperature at peak load. In fact, most of the time when the air-conditioned room is running, it will not be at peak load, which makes the cooling supply surplus, and it is switched to middle and low gear operation to reduce the cooling output, thereby maintaining the heat balance of the room. Choose a fan-coil unit, in addition to the cooling capacity to meet the calculated cooling load requirements, it also needs to meet the sensible and latent heat matching to meet the room heat and moisture ratio requirements; the air volume must meet the temperature difference of the supply air, the number of air changes and the air flow organization Wait for the use requirements.
The fan coil is used as the terminal equipment of the central air conditioner, and its quality determines the indoor air conditioning effect. At the same time, its cleaning problems also directly affect the use of central air conditioning. There are many dust particles in the atmosphere. Under the action of long-term extraction and return air, the aluminum fins of the fan are full of dust and dirt. At this time, on the one hand, the heat exchange between the chilled water and the hot air is affected, and the temperature of the air is affected; On the one hand, it also affects the delivery of cold air that has cooled down after heat exchange, resulting in the phenomenon that the air conditioner is turned on and the room is still not cold. Because the central air-conditioning host sends 7 degrees of water into the fan coil after cooling, and it is exchanged in the fan coil to become 15--16 degrees of cold wind, which reduces the room temperature. Therefore, after the central air conditioner is used for a period of time, the aluminum fins of the fan must be cleaned to solve the above problems.
