Fresh air ventilator with energy recovery function

Abstract

The invention relates to a bidirectional flow ventilation and air exchange device with an energy recovery function, in particular to a fresh air ventilator with an energy recovery function. A motor of a fresh air machine and a motor of an exhaust fan are both arranged in a fresh air flow channel or an exhaust flow channel. For an energy recovery device which is applied to buildings in severe cold and cold regions and mainly used for recovery of heat in exhausted air in the heating season, the motor of the fresh air machine and the motor of the exhaust fan are both arranged in the fresh air flow channel, so that heat of the motor of the fresh air machine and heat of the motor of the exhaust fan are both fed in a room along with fresh air, the air output temperature of the fresh air can be improved, and then the energy recovery efficiency of the device under the heating work condition is improved. For the energy recovery device which is applied to buildings in hot summer and warm winter zones and mainly used for recovery of cold in exhausted air in the refrigerating season, the motor of the fresh air machine and the motor of the exhaust fan can be both arranged in the exhaust flow channel, so that heat of the motor of the fresh air machine and heat of the motor of the exhaust fan are both exhausted out of the room along with the exhausted air, the air output temperature of the fresh air can be lowered, and then the energy recovery efficiency of the device under the refrigerating work condition is improved.

Description

Technical field: [0001] The invention relates to a ventilation and ventilation device with two-way flow and energy recovery function, which can recover the energy in the exhaust air while sending fresh air into the room. Background technique: [0002] Energy recovery fresh air ventilator is generally composed of energy recovery core, fresh air fan, exhaust fan and other main components. The fresh air and exhaust fan respectively drive fresh air and exhaust air to flow through the energy recovery core for energy exchange, while sending fresh air into the room. Capable of recovering the energy in the exhaust air. In the traditional energy recovery fresh air ventilator, the fresh air fan and its motor, the exhaust fan and its motor are respectively located in the fresh air flow channel and the exhaust air flow channel. The heat is discharged outside with the exhaust air. For the energy recovery device used in buildings in severe cold and cold regions, mainly used to recover t...

AI Technical Summary

Problems solved by technology

For the energy recovery device used in buildings in severe cold and cold regions, mainly used to recover the heat in the exhaust air during the heating season, the heat generated by the motor of the fresh fan is used, while the heat generated by the motor of the exhaust fan is wasted; For energy recovery devices used in buildings in hot summer and warm winter regions, mainly used to recover the cooling capacity of the exhaust air during the cooling season, the heat generated by the fresh fan motor will offset part of the recovered cooling capacity, resulting in energy loss
