[0004] The application number is 01238137, and the name is a new air conditioner for fresh air. In addition to the cross-flow fan for heat exchange, a centrifugal fan is also installed in the air conditioner for ventilation. These invention patents have actually changed the structure of the original household split air conditioner. At the same time, turning on the ventilation fan to introduce fresh air is not based on the indoor air quality, there is no definite quantitative standard, and it cannot guarantee that the indoor air quality is in the best condition

Embodiment Construction
[0010] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.
[0011] Such as figure 1 As shown, the present invention mainly includes a filter screen 1, a fresh air pipe 2, a solenoid valve 3, a signal line 4, and a fresh air detector 5.
[0012] Install the fresh air detector 5 on the wall of the air-conditioning room, the sensor for detecting indoor carbon dioxide, formaldehyde, tobacco and organic compound content is housed in the fresh air detector 5, one end of the fresh air pipe 2 is connected with the air return port of the air conditioner indoor unit 6, and the other end is connected with the air return port of the air conditioner indoor unit 6. The refrigerant and condensed water pipes lead to the outside through the hole 7 of the outer wall, and a filter screen 1 is installed at the mouth of the outdoor pipe to ensure the cleanliness of the fresh air entering the room; a solenoid valve 3 a...

Intelligentized fresh air lead-in device of separation-typed air conditioning consists of filtration net, fresh air pipeline electromagnetic valve and fresh air probe. Fresh air pipeline controlled by fresh air probe are combine with indoor machine of separation-typed air conditioning, avoiding blind for often opening window to ensure air fresh in room and scientific and quantitative for air quality. Separation-typed valve fitted with fresh air pipeline is controlled by fresh air probe through signal wire, its one end is linked with air-back opening of air conditioning indoor machine and another end is to the outside with filtration net on pipe opening outside. The invention just needs to add a fresh air pipeline without changing the structure of the original separation-typed air condition and the hole prepared for installing separation-typed air conditioning. The invention has ensured the air quality in room with notable energy saving effect and good economic benefit.
Description
technical field [0001] The invention relates to an air-conditioning fresh air introduction device, in particular to a split-type air-conditioning intelligent fresh air introduction device that can automatically introduce outdoor fresh air according to indoor air quality, and belongs to the technical field of building environment and equipment engineering. Background technique [0002] With the progress of the times, split air conditioners have become more and more popular. Because split air conditioners do not have fresh air introduction and heat and humidity treatment devices like central air conditioners, people mainly rely on outdoor air to pass through doors and windows when using split air conditioners. The possible gaps penetrate into the room. When the indoor air feels dirty, open the doors and windows to let the outdoor fresh air directly enter the room. When you feel that the indoor air is fresh, close the doors and windows; or open a gap for a long time to introduc...
