[0001] The application claims priority to Chinese patent application No.
202011461873.4, filed on December 9, 2020, the entire contents of which are incorporated herein by reference.
TECHNICAL FIELD

BACKGROUND
BACKGROUND
[0003] Near-zero energy consumption buildings are also called "passive houses". This concept is based on the low energy consumption building concept that emerged in the 1980s in Germany. They believe that passive houses should be buildings that can maintain a comfortable indoor thermal environment without adopting active heating and air conditioning systems. The heating and refrigerating energy consumption per square meter required by the passive houses saves as high as 90% energy compared with that of traditional buildings.
Passive house buildings have excellent tightness and heat insulation measures, and must use a fresh air system to ventilate indoor air. However, the fresh air device in the prior art cannot be well adapted to a passive house, the energy-saving effect thereof is poor, and in particular, the regulation of the control of cold and hot temperature cannot achieve an excellent state, such that residents still need to cool or heat through coal-fired electric appliances after living in the building. Therefore, it is necessary to provide a cold and heat source fresh air device for a building with near-zero energy consumption to solve the above-mentioned problems.
