Description
Technical field
The present invention relates to a kind of fresh air heat pump, especially a kind of controllable temperature and adjusting concentration of interior carbon dioxide, PM2.5 and
The fresh air heat pump of harmful gas concentration.
Background technique
With economic development, largely using fossil fuels such as coal and petroleum, great amount of carbon dioxide and sulfur dioxide are generated
And dust.Final air pollution is serious and air PM2.5 concentration increases, and seriously affects the work and life of the people.With people
People's improvement of living standard, the requirement to air quality are also improving.Fresh air ventilator 100 as shown in Figure 1, it is interior to be equipped with fresh air
Outdoor fresh air is sent to interior by channel and return air channel, fresh air channel, and indoor air is sent to outdoor by return air channel, can and
The indoor air of Shi Genghuan, more and more as house equipment application in daily life.
Air exchange system inside traditional fresh air ventilator is as shown in Fig. 2, include air-to-air total heat exchanger 101, outdoor fresh air mistake
Filter 102, indoor return air filter 103, indoor breeze fan 104, indoor exhaust wind blower 105.It is equipped in fresh air ventilator new
Wind channel and return air channel, fresh air channel and return air channel intersect in " X " type, and the entrance and return air channel of fresh air channel
Outlet in the side of cabinet, the outlet of fresh air channel and the entrance of return air channel are in the other side of cabinet, outdoor fresh air filtering
Device 102 is mounted on the inlet of fresh air channel, and indoor breeze fan 104 is mounted on the exit of fresh air channel, indoor return air mistake
Filter 103 is mounted on the inlet of return air channel, and the exit of return air channel is arranged in indoor exhaust wind blower 105, full heat heat exchange
The intersection of fresh air channel and return air channel is arranged in device 101, is acted on by indoor breeze fan 104, outdoor fresh air is by room
Outer new wind filter 102, air-to-air total heat exchanger 101 are discharged into interior from the outlet end of fresh air channel, pass through indoor exhaust wind blower 105
Effect, indoor return air are discharged by indoor return air filter 103, total-heat exchanger 101 from the outlet end of return air channel, and full heat is changed
Hot device 101 carries out heat exchange to the air in fresh air channel and return air channel.
Above-mentioned traditional fresh air ventilator is that outdoor air is simply sent to interior, has significant limitation,
The shortcomings that there are following aspect：
1, the temperature for being transported to indoor air is non-adjustable.
It is transported to the heat of indoor air recovery section indoor air draft, but temperature is to cannot be adjusted.In summer and
In winter, being transported to indoor air can be hot or cold, makes indoor occupant feel to feel bad, needs to increase refrigeration or heating power,
It is not energy-efficient.
2, the humidity for being transported to indoor air is non-adjustable.
When outside humidity is greater than indoor humidity, the humidity for being transported to indoor air also can be bigger than indoor air humidity,
Make indoor occupant feel to feel bad, needs to increase dehumidifier, it is not energy-efficient.
