Abstract

The invention discloses an energy-saving coiled tube fan control method capable of improving the comfort degree of environment. In the method, devices need to be adopted as follows: a power supply device, an anti-interference filtering device, a speed-regulating device, a power factor correcting device, a microcontroller, a humiture sensor, a fan motor, a fan impellor and a regulating panel, wherein the microcontroller can process data such as fan return air temperature and humidity which are detected by the humiture sensor and current, voltage and power factors input by the power supply device; the microcontroller also can send instruments to control the speed-regulating device accurately, and further can control the fan motor to run at variable speed so as to achieve the effect of constant temperature; the constant-temperature control mode can improve the temperature comfort degree under the refrigeration environment; the power factor is improved, and line loss can be reduced. By using the control method provided by the invention, a great amount of electricity energy consumption can be saved, and the running cost of fan equipment can be lowered.

Description

technical field

[0001] The invention relates to a control method of a coil fan, more specifically, an energy-saving control method of a coil fan. Background technique

[0002] At present, the control method of the terminal fan of the air conditioner is to use a low-power AC motor, and the working state of the motor is usually manually controlled in three gears with different speeds. Moreover, the temperature controller of the air-conditioning fan is controlled by the principle of constant wind speed and variable temperature. The temperature controller is externally connected with a temperature sensor. When the actual temperature value is lower than the set temperature value by a certain range (0.5-1 degree), the control solenoid valve disconnects the cold water passage; when the actual temperature value is higher than the set temperature value by a certain range (0.5 -1 degree), the control solenoid valve is connected to the cold water passage. There are two defects in thi...
