Control method of ventilation module, fresh air conditioner and fresh air conditioning device

Abstract

The invention discloses a control method of a ventilation module, a fresh air conditioner and a fresh air conditioning device.The ventilation module comprises a volute, a filter screen, a wind wheel and a motor, the volute is provided with an inner cavity, an air inlet and an air outlet, the air inlet and the air outlet communicate with the inner cavity, the motor, the filter screen and the wind wheel are installed in the inner cavity, the motor is connected with the wind wheel, and the filter screen is connected with the motor. The motor comprises a motor monomer and a motor controller, the motor monomer comprises a stator assembly and a rotor assembly, the motor controller comprises a power supply circuit, a microprocessor MCU, an inverter circuit and a motor operation parameter detection circuit, the power supply circuit supplies power to each circuit, and the microprocessor MCU controls the motor monomer through the inverter circuit. The motor operation parameter detection circuit is used for detecting the real-time rotating speed R of the rotor assembly and transmitting a detection signal to the microprocessor MCU. The control method comprises the following steps that the microprocessor MCU compares the real-time rotating speed R with a plurality of set rotating speeds and adjusts the working current of the motor according to the comparison result so as to adjust the running power of the motor.

Description

Technical field: [0001] The invention belongs to the field of air conditioners, and in particular relates to a control method of a ventilation module, a fresh air air conditioner, and a fresh air air conditioner. Background technique: [0002] An air conditioner with a ventilation module (such as an air conditioner fresh air module) is a new type of air conditioner that is currently emerging. At present, most air conditioners on the market do not have a ventilation module. The fresh air air conditioner is named because of the addition of a ventilation module. Fresh air is brought into the room to help improve indoor air. Fresh air conditioners were born, and major manufacturers have begun to develop them. However, due to various problems such as cost and control, the current control system of the ventilation module is connected to the air-conditioning control system, and the ventilation module is powered by the air-conditioning control system, so the change of the operating ...
