Fan coil unit, also known as central air conditioning terminal equipment, is mainly composed of electric motor, cooling pipe and water pan.
Motor function: blow the wind from the air inlet to the cooling pipe.
The role of the cooling pipe: the cold water above the central air conditioner is circulating.
The function of the receiving water tray: receives the water evaporated on the side of the cold pipe, and then flows out through the drain pipe.
A device composed of an exhaust pipe and fins, which can introduce a flowing medium, and then let a fan force the air flow through to achieve the purpose of heating or cooling.
The fan coil is mainly composed of a low-noise motor and a coil. The fan sends indoor air or outdoor mixed air into the room after being cooled or heated by the instrument cooler, so that the indoor temperature is reduced or increased to meet people's comfort requirements. The cold (hot) medium water in the coil is centrally supplied by the machine room.
Fan coil is the ideal end product of central air conditioning, which is widely used in hotels, office buildings, hospitals, commercial and residential buildings, scientific research institutions, etc. In order to meet the design choices of different occasions, the types of fan coil are: horizontal concealed fan coil (return air box) horizontal fan coil, vertical concealed fan coil, vertical open fan coil, card type two outlet fan coil, card type four outlet fan coil and wall mounted fan coil etc.

The main features of the fan coil.
Fan coil structure is exquisite, compact, durable, beautiful and generous.
The fan coil is made of high-quality galvanized sheet shell, the condensate plate is molded, the insulation material has no welds and solder joints, and is connected with the water plate as a whole according to the fire protection code.
The fan coil is small in size: lightweight design, convenient installation of drainage pipes and lines, left and right connections and return air can be replaced at any time according to site conditions, and the device can be installed in any space.
The fan coil has high efficiency: advanced pipe expansion technology ensures that the copper pipe is in close contact with the aluminum foil and has good heat transfer performance.
Fan coil low noise: fan and airflow structure design is reasonable, fan coil with high quality sound-absorbing insulation materials, the unit noise is lower than the national standard 1-3db(A).
The fan coil has low energy consumption: the fan and the heat exchanger are matched reasonably, and the air volume is adjusted in three steps to minimize the power consumption of the fan.
Fan coil unit (fan coil unit) is a widely used terminal equipment in the purchase of central air conditioning. The full name of this specification is the central air conditioning fan coil unit. Its simple classification is as follows:.
According to the form of central air conditioning fan coil is divided into: horizontal dark installation, horizontal open installation, vertical dark installation, vertical open installation, card type five, horizontal fan coil according to the thickness can be divided into ultra-thin and ordinary type.
According to whether the condensate pump can be divided into: ordinary type, luxury type.
According to the static pressure of the unit, the central air conditioning fan coil can be divided into: 0Pa,12Pa,30Pa,50Pa,80Pa and so on.
The central air-conditioning fan coil can be divided into two rows and three rows according to the number of rows. There are two controls and four controls: two controls, namely, ordinary fan coil cooling water in summer and heating water in winter. Four control fan coils are mostly used in some more luxurious places. The fan coil can take hot water and cold water at the same time, and some rooms can be cooled and heated according to needs.

Construction preparation of fan coil unit.
1. The main and auxiliary materials of the fan coil unit have arrived at the site, and all necessary installation tools have been prepared. The site, water source and power supply are tested before installation.
2. After the construction of the building structure is completed, the roof waterproof layer is completed and the baseline is measured.
3. After the main pipe of the air conditioning system is installed, the position and elevation of the reserved nozzle of the branch pipe connecting the fan coil shall meet the requirements.
4. The construction plan has been prepared and the safety technical disclosure has been completed.
5. Check the relevant professional drawings and architectural decoration drawings to check whether the position and elevation of the fan coil unit are correct. If there is any problem, study and solve it with the design and relevant personnel in time, and deal with the change negotiation record.
6. Motor trial operation: The fan coil unit should be energized according to 10% of the total number of three-speed trial operation inspection devices. There is no friction in the mechanical part, no leakage in the electrical part, stable operation and normal noise.
7. Water pressure test of surface cooler: The water pressure test of fan coil surface cooler shall be carried out according to 10% of the total number of units without leakage.
