Abstract

The invention provides an energy-saving control device and control method for an air conditioner fresh air machine. The energy-saving control method comprises the steps of S1: performing online monitoring on the temperature and humidity parameters of outdoor air of an air conditioner via an outdoor temperature sensor and outdoor humidity sensor, and performing online monitoring on the indoor CO2 concentration parameter via an indoor CO2 concentration sensor; S2: calculating the outdoor air enthalpy value HW based on the outdoor temperature and humidity parameters acquired through online monitoring; S3: comparing the outdoor air enthalpy value HW with a preset outdoor air enthalpy value and dynamically determining an indoor CO2 concentration optimization set value yset according to the enthalpy value comparison result; S4: comparing the indoor CO2 concentration value y obtained through online monitoring and the indoor CO2 concentration optimization set value yset, and emitting a fresh air machine frequency changer control signal according to the deviation value thereof to realize dynamic control of the quantity of fresh air. By formulating the optimal operating adjustment mode, the indoor air quality requirement is met and energy is saved.

Description

technical field [0001] The invention relates to a control device and a control method of air-conditioning equipment, in particular to an energy-saving control device and a control method of an air-conditioning fresh fan. Background technique [0002] my country's building energy consumption accounts for about 1 / 3 of the total social energy consumption, of which the energy consumption for air heat and humidity environment control accounts for more than 65%, which has a significant impact on the sustainable development of my country's social economy, and fresh air treatment Energy consumption accounts for about 30%-40% of the total energy consumption of air conditioners. The introduction of outdoor fresh air into the air-conditioning system is the key to ensuring good indoor air quality, but the energy consumed by the fresh air treatment of the air-conditioning system is also very large. Therefore, on the premise of satisfying the indoor air quality, reasonable control of the f...
