Fan Coil Set

Most offices, hotel rooms and shopping malls such as fan coil units are generally used with AC motors, pick up in the past few years of experience, these all have to use the AC motor life president, low maintenance machine, advantages of low randomness, different brands of AC motor commonality, interchangeable and production costs, but in terms of energy efficiency, with the fan coil brushless DC motor compared to a big difference too.
Our new fan coil units, are using the general single-phase AC AC motor, but joined a group of patented electronic control circuit, at low wind speeds, improve energy efficiency rate of up to 60-66% in energy conservation side, very close to the fan coil DC brushless motor, but the costs are much lower.
In the past 30 years, before the leaves are centrifugal fan coil using AC motors, after joining a group of patented control electronics, AC motor when lowering operating efficiency will not fall, so the power will be with the speed decline to a normal VI, for example (with McQuay's MC600BC do benchmarks) when the speed dropped from high 1050r.pm to 550r.pm, the power from 120W, down to 30W, but did not join the patent when the control electronics, 1050r.pm power consumption is 125W, when 550r.pm is 90W. thus at low speed, the motor itself will be much lower heat, thus reducing the cooling load of the air conditioning system to further enhance the energy efficiency and, low heat of the motor can improve the life of the motor, and the motor bearings also low due to heating and electronic control soft start and extended.
The fan coil energy-saving renovation package, especially for the model by fan coil 600-1400 and design, it can be used directly in the fan coil old AC motor, therefore, can save a lot of replacement renovation costs, the original energy efficient fan-coil can Hang effect, do not need to replace the entire fan coil, thus reducing the work of the project.
Internal structure
The fan coil within the energy saving package includes a major renovation of the control box; internal installation of a motor drive circuit pull, pull the controller to the motor drive circuit provided together with the speed of a change in the exchange of high-voltage and AC current, while providing a PWM signal to control the motor speed to control the motor speed should be different because of different fan coil the necessary power to the existing three controllers provide users used with different types of fan coil units, most models can output 250W power, and can also connect two AC motors synchronization work.
Product Type
Code # of motor input AC voltage output power
AC XX XXX V XXX W
2.1) AC 01 220V 85W
01 = one motor 220VAC = 200VAC to 240VAC 50 / 60Hz
02 = two motors 277VAC = 2650VAC to 295VAC 50 / 60Hz
2.2) fan coil in the market, it is generally the amount of wind to distinguish models,
viz: 200, 300, 400, 600, 800, 1000, 1200 and 1400 of the eight models,
600 wind following models usually only a motor,
800-1400 usually two motors,, therefore,
This is a retrofit kit with two controllers, used with different types of fan coil.
2.3) different types of controllers: -
2.3.1) by 400-600 wind fan coil controller should match AC01-220V125W
2.3.2) 800-1400 wind from the fan coil controller should match AC02-220V250W
