The invention relates to a heat recovery fresh air handling unit suitable for an independent temperature and humidity control system and a control method of the heat recovery fresh air handling unit, and belongs to the technical field of heating and ventilation equipment. The heat recovery fresh air handling unit is mainly composed of an exhaust fan, a force draft fan, a primary filter, a heat recoverer, a humidifier, a dehumidification and refrigeration system, a self-control device and the like. In different seasons, the heat recovery fresh air handling unit can be controlled to work in three different working modes. According to the heat recovery fresh air handling unit suitable for the independent temperature and humidity control system and the control method of the heat recovery fresh air handling unit, dual energy conservation through the air-exhausting heat recovery technology and the independent temperature and humidity control system can be achieved, and meanwhile the heat recovery fresh air handling unit has the characteristics of being high in integration degree, convenient to manage, small in occupied space, simple in matched pipeline, high in engineering adaptability and the like.
Description
technical field [0001] The invention belongs to the technical field of heating and ventilation equipment, and relates to a heat recovery fresh air unit suitable for an independent temperature and humidity control system and a control method thereof. Background technique [0002] Energy conservation and emission reduction has been paid more and more attention. The 2015 government work report put energy conservation and emission reduction in a very important position, emphasizing that "we must fight the tough battle of energy conservation, emission reduction and environmental governance". As an important part of energy conservation and emission reduction, building energy conservation has also attracted much attention. The energy consumption of the HVAC system generally accounts for 30%-50% of the total energy consumption of the entire building. It is of obvious significance to explore the energy-saving technology of the HVAC system and take it as an important breakthrough to r...
