Problems solved by technology
In summer and winter, the air delivered to the room will be hot or cold, which will make the indoor occupants feel uncomfortable, and it is necessary to increase the cooling or heating power, which is not energy-saving.
[0007] 2. The humidity of the air delivered to the room cannot be adjusted
[0008] When the outdoor humidity is greater than the indoor humidity, the humidity of the air delivered to the room will also be higher than the indoor air humidity, which will make the indoor people feel uncomfortable, and it is necessary to add a dehumidifier, which will not save energy.
[0009] 3. It cannot solve the ventilation adjustment when the outdoor carbon dioxide concentration is higher than the indoor concentration
worsen indoor air quality

The invention provides a fresh air heat pump. A fresh air passageway and an air return passageway intersecting with the fresh air passageway are arranged in a machine box of the fresh air heat pump. The fresh air heat pump comprises an air conditioner heat pump system. The air conditioner heat pump system comprises a compressor, an electronic expansion valve, a four-way valve, a fresh air processing heat exchanger and an energy recycling heat exchanger. A low-pressure opening and a high-pressure opening of the compressor are connected with two valve openings of the four-way valve. The fresh air processing heat exchanger is installed at the outlet end of the fresh air passageway, and the energy recycling heat exchanger is installed at the outlet end of the air return passageway. The fresh air processing heat exchanger and the energy recycling heat exchanger are communicated, and the electronic expansion valve is arranged between the fresh air processing heat exchanger and the energy recycling heat exchanger. The other two valve openings of the four-way valve are connected to the fresh air processing heat exchanger and the energy recycling heat exchanger. The air conditioner heat pump system is arranged on the fresh air heat pump, and therefore control over the indoor air supply temperature and humidity is achieved, and the indoor carbon dioxide concentration, the concentration of PM2.5 and the concentration of harmful gas can be regulated and controlled.
Description
technical field [0001] The invention relates to a fresh air heat pump, in particular to a fresh air heat pump which can control and adjust indoor carbon dioxide concentration, PM2.5 and harmful gas concentration. Background technique [0002] With the development of the economy, fossil fuels such as coal and oil are used in large quantities, producing a large amount of carbon dioxide, sulfur dioxide and dust. In the end, the air pollution is serious and the concentration of PM2.5 in the air increases, which seriously affects people's work and life. With the improvement of people's living standards, the requirements for air quality are also increasing. Such as figure 1 The fresh air ventilator 100 shown is provided with a fresh air channel and a return air channel, the fresh air channel sends the outdoor fresh air to the room, and the return air channel sends the indoor air to the outside, so that the indoor air can be replaced in time, more and more Many places are used a...
