Structure and main properties of fan coil units

Fan coil units rely mainly on the role of fan forced, when the air is heated by the heater surface, thereby strengthening the convective heat transfer between the radiator and air, quickly heating the room air. Fan coil air conditioning system is the end of the device, its working principle is continuously recirculated air inside the room where the unit of the air through the cold (hot) coil after cooling (heating) in order to keep the room temperature constant. Typically, the new air handling units into the room to meet the needs of fresh air-conditioned room.


However, the new wind ventilators that because of this heating method is based only on convection heat transfer, which results in less than optimal indoor comfort level, it applies only to people staying a short time places, such as: office and hotel instead ordinary residence. With the addition of the fan, improve the cost and operating costs, equipment maintenance and management is also more complex. Fan coil control scheme to use more local control, sub-simple control and temperature control of two.

Simple Controls: Use direct manual three-speed switch control three-speed fan and start and stop the conversion.
Temperature control: STC series thermostat set temperature based on a comparison with the actual test temperature operation, automatic control STV series of electric two / three-way valve opening and closing; three-speed fan conversion. Or directly control three-speed fan and start and stop the conversion, so as to achieve a constant temperature by controlling the flow of water or the air volume system.

As central air-conditioning fan coil terminal equipment, its quality determines the effects of indoor air conditioning. Air curtain understand its performance is mainly sent to protect the cold (hot) the amount of security, the amount of air, noise than the value of the condensate does not leak and electrical, sheet metal design is reasonable and so on.
