Fan-coil system is to put the unit consisting of fan and coil directly in the air-conditioned room. The fan sucks in air, filters it, heats it or cools it through the coil, and then enters the air-conditioned room on the spot to achieve the purpose of air conditioning.
The fresh air needed indoors is usually sent through the pipeline after the outdoor air is centrally treated by the fresh air treatment unit. The refrigerant used in the fan coil unit is supplied centrally, which belongs to semi-centralized air conditioning system. In this system, cold (or heat) is brought into the air-conditioned room by air and water respectively, which belongs to the air-water system. ?
The fans of fan-coil units are generally centrifugal fans or cross-flow fans, and the blades are galvanized forward, with low noise and large air volume. Equipped with a low-noise motor, the fan speed can be changed by adjusting the input voltage of the motor, so that it can be converted into high, medium and low air volume.
The coil is a high-efficiency finned heat exchange tube, made of corrugated aluminum fins and high-quality copper tubes. After hydraulic or mechanical expansion, the fins are in close contact with the copper tube, thus improving the heat exchange efficiency. The compression strength of the coil is good, 98 1kPa, 17 15kPa.

Principle of evaporative cooling and ventilation device;
According to the natural physical phenomenon of "water absorbs heat by evaporation, and evaporation area affects evaporation efficiency", air absorbs a lot of heat through the evaporation wet curtain whose actual heat exchange area is many times that of the surface, thus achieving the purpose of cooling.
Characteristics of "Multilayer Corrugated Fiber Laminate" Wet Curtain
The core component is the direct evaporation wet curtain-"Multilayer Corrugated Fiber Laminate" wet curtain is a special kind of "Multilayer Corrugated Fiber Laminate" invented by Sweden, which is characterized by good water absorption and air permeability, strong texture, water immersion resistance and no deformation; Corrosion resistance, normal service life can exceed 5 years.
Ventilation principle of evaporative cooling ventilation device
Evaporative cooling ventilation unit is suitable for open and semi-open environment, and can directly transport natural wind and cooled cold air. The outdoor fresh air is filtered and cooled by Corelli evaporative cooling ventilation unit, and then continuously transported indoors, and the indoor air with peculiar smell, dust, turbidity and sultry air is discharged to the outside.
