Abstract

The invention discloses a temperature frequency conversion energy-saving system of an intelligent fresh air ventilator. The temperature frequency conversion energy-saving system of the intelligent fresh air ventilator comprises a PLC mainframe module, an A / D conversion module, a D / A conversion module, a logic control part, a chilled water outlet water temperature sensor, a chilled water return water temperature sensor, a cooling water return water temperature sensor and a cooling water outlet water temperature sensor; a PLC mainframe is connected with the logic control part, the PLC mainframe module is connected with the D / A conversion module, the PLC mainframe is connected with the A / D conversion module, the A / D conversion module is connected with the chilled water outlet water temperature sensor, the chilled water return water temperature sensor, the cooling water return water temperature sensor, the cooling water outlet water temperature sensor, a chilled water system pressure sensor and a cooling water system pressure sensor, and the logic control part adopts the fuzzy PID control. According to high temperature, cold air is generated, the temperature is reduced, in winter, according to low temperature, hot air is generated, the temperature rises, and therefore the intelligent temperature control is achieved.

Description

technical field [0001] The invention relates to temperature control, in particular to a temperature conversion and energy-saving system of an intelligent fresh air fan. Background technique [0002] In the current life and work, because the decoration materials such as paint, paint, wood, plywood, etc. are used in the decoration of new houses, they contain harmful gases such as ammonia, formaldehyde, ethylene, and benzene to varying degrees; there is also a phenomenon that the home is stuffy, that It is because there is not enough ventilation in the room, odor and moisture accumulation, and the waste gas generated by human activities cannot be discharged in time, which makes people feel dizzy and bloated; second-hand smoke contains more than 7,000 chemical substances, about 70 of which are carcinogenic, It is extremely harmful to the human body; these things will cause harm to the air and at the same time cause great harm to the human body. With the development of society, ...
