Problems solved by technology

[0003] The current fresh air system cannot achieve a constant output air volume. This is because as the fresh air system works longer, the blockage of the filter in the fresh air system will become more and more serious, resulting in the output air volume of the fresh air system gradually attenuating.

Embodiment Construction

[0016] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0017] figure 1 It is a schematic flow chart of the air volume control method of the fresh air system, including the following steps:

[0018] S11: Obtain the current output air volume of the fresh air system and the target output air volume of the fresh air system;

[0019] S12: If the current output air volume of the fresh air system is smaller than the target output air volume of the fresh air system, send a control command to the power supply of the motor of the fresh air system to increase the current input voltage of the motor.

[0020] The air volume control method and device of the above-...

Abstract

The invention provides an air amount control method and device of a fresh air system. The method includes the steps that after the current output air amount and target output air amount of the fresh air system are obtained, the mathematic relation between the current output air amount and target output air amount of the fresh air system is judged; if the current output air amount of the fresh air system is smaller than the target output air amount, it means that the amount of fresh air conveyed indoors is insufficient, a control instruction is sent out to a power source of a motor of the fresh air system, the voltage from the output end of the power source to the motor is increased so as to increase the current input voltage of the motor of the fresh air system, and therefore the rotating speed of the motor of the fresh air system is increased, the current output air amount conveyed indoors of the fresh air system is increased, and the output air amount balance can be maintained.

Description

technical field [0001] The invention relates to the technical field of fresh air systems, in particular to an air volume control method and device for a fresh air system. Background technique [0002] The fresh air system is a new type of indoor ventilation and exhaust equipment, which sends fresh air to the closed room, and uses outdoor fresh air to update indoor dirty air such as carbon dioxide, so as to maintain the cleanliness of the indoor air and meet the needs of indoor fresh air exchange. [0003] The current fresh air system cannot achieve a constant output air volume. This is because as the fresh air system works longer, the blockage of the filter in the fresh air system will become more and more serious, resulting in a gradual attenuation of the output air volume of the fresh air system. Contents of the invention [0004] Based on this, the present invention proposes an air volume control method and device for a fresh air system, which can increase the output ai...
