Fan Coil MotorAlso known as the terminal equipment of the central air conditioner, it is mainly composed of a motor, a cooling tube and a drain pan. What is its working principle? Ever Power answers for you.

The function of the motor: Blow the wind from the water inlet to the cold pipe. The wind will be cold wind when it comes out from the water outlet.

The function of the cold tube: circulate the cold water on the central air-conditioning host.

The role of the drain pan: to receive the water evaporated from the side of the cold pipe, and then flow away through the drain pipe.

It is a kind of equipment that is composed of platoons and fins that can introduce flowing medium, and then allows the fan to force the air flow through to achieve the purpose of heating or cooling.

Fan Coil Motor

The fan-coil unit is mainly composed of low-noise motors and coils.The fan cools or heats the indoor air or outdoor mixed air through the surface cooler and sends it into the room to reduce or increase the indoor temperature to meet people's comfort requirements.The cold (hot) medium water in the coil is supplied centrally by the machine room.

Fan coils are ideal end products for central air conditioning. Fan coils are widely used in hotels, office buildings, hospitals, commercial and residential buildings, and scientific research institutions.In order to meet the design and selection of different occasions, the types of fan coils include: horizontal concealed (with return air box) fan coils, horizontal exposed fan coils, vertical concealed fan coils, and vertical exposed fan coils , Cassette two-outlet fan coils, cassette four-outlet fan coils and wall-mounted fan coils, etc.

The fan-coil unit is mainly composed of low-noise motors and coils.The fan cools or heats the indoor air or outdoor mixed air through the surface cooler and sends it into the room to reduce or increase the indoor temperature to meet people's comfort requirements.The cold (hot) medium water in the coil is supplied centrally by the machine room.  

working principle

The fan coil mainly relies on the forced action of the fan to heat the air when it passes through the heater surface, thus strengthening the convection heat exchanger between the radiator and the air, and can quickly heat the air in the room.The fan coil is the end device of the air conditioning system. Its working principle is to continuously recirculate 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, it is sent to the room after being processed by the fresh air unit to meet the needs of fresh air volume in the air-conditioned room.

However, because this heating method is only based on convection heat exchange, which results in an unreachable level of indoor comfort, it is only suitable for places where people stay for a short time, such as offices and hotels, and not for ordinary residences.Due to the addition of fans, the construction and operating costs are increased, and the maintenance and management of the equipment are also more complicated.

Fan coil control mostly adopts local control scheme, which is divided into simple control and temperature control.Simple control: use the three-speed switch to directly manually control the three-speed conversion and start-stop of the fan.Temperature control: The STC series thermostat automatically controls the opening and closing of the STV series electric two/three-way valve according to the comparison and calculation of the set temperature and the actual detected temperature; the three-speed conversion of the fan.Or directly control the three-speed conversion and start-stop of the fan, so as to achieve the purpose of constant temperature by controlling the water flow or air volume of the system.

As the terminal equipment of the central air conditioner, the quality of the fan coil unit determines the indoor air conditioner effect.The performance is mainly the guarantee of the cold (heat) supply, the guarantee of the air supply, the numerical ratio of noise, the non-leakage of condensate, and the rationality of the design of electrical appliances and sheet metal parts, etc.
