Principles and characteristics of fan coil system

Fan coil is one of the important types of central air-conditioning, due to the ease of installation, use of effective, less capital investment and the high popularity.

Fan coil advantage

Fan coil air conditioning system is a semi-centralized air-conditioning system in the central air conditioning system, as a terminal device system, to be located in each air-conditioned room. Central air-conditioning fan coil system with its flexible layout, easy adjustment, saving return air duct, lower operating pressures and high degree of standardization of the outstanding advantages, has been widely used in hotels, office buildings, commercial buildings, apartments, hospitals and other high-level multi-room air conditioning systems.

Fan coil system principle and characteristics - works

Fan coil units driven by the motor, by changing the input voltage regulator wind speed, so that the amount of wind turbines to meet the needs of different interior. Fans from the power control, the indoor fan coil has a great supply of hot and cold regulation. Thus, even if the power system fan air transport, but also serve to strengthen air convection and heat transfer effects.

When the refrigerant flowing in the pipe, since the temperature of the refrigerant is lower than the air temperature, surface of the pipe is easy to form condensed water in wet condition under the mediation of the coil also has the role of heat exchange and mass exchange. To make the coil sufficient to bear the entire load of air conditioning in the room, it normally takes three to four rows of tube rows.

Condensate in the bottom-mounted coil condensate drain pan, close the disc can be discharged quickly to prevent excessive condensation of water on the affected system.

Fan coil system principle and characteristics - attention problems

Fan coil units require a higher quality of the unit. Otherwise, the maintenance workload. Units require low noise, when the noise is limited, the unit sanctuary pressure head small, and thus indoor air distribution restrictions applicable to the depth less than 6M, air-conditioned room. Water disc content easy to breed bacteria, environmental pollution restrictions.

Fan coil central air conditioning system is a common type of central air-conditioning, in a small space plays an important role. Whether the effect is conditioned from an economic point of view, fan coil units are ordinary household use central air conditioning better choice.
