The present invention provides a fresh air conditioner indoor unit, a fresh air conditioner and a control method thereof, wherein the fresh air conditioner indoor unit includes a shell, and the shell is configured with a fresh air inlet, a fresh air outlet, a first return air inlet, and a second return air inlet , the return air outlet, there is a heat exchange core in the shell, and the heat exchange core has a first flow channel and a second flow channel that intersect with each other and form an independent one. The fresh air inlet, the first flow channel and the fresh air outlet are connected to form a fresh air flow channel. The return air inlet, the second flow channel, and the return air outlet are connected to form a return air discharge flow channel. There is a damper in the fresh air flow channel between the first flow channel and the fresh air outlet. The damper has the function of making the second return air inlet and the fresh air outlet The first position for the connection and the second position for the connection between the first flow channel and the fresh air outlet. According to the present invention, a single air valve is used to realize the switching of the air passage in the fresh air mode and the return air mode, which simplifies the structure of the indoor unit and reduces the manufacturing cost of the air conditioner.
Description
technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to an indoor unit of a fresh air conditioner, a fresh air conditioner and a control method thereof. Background technique [0002] With the improvement of people's living standards, the quality of life has become a hot spot pursued by the public. However, nowadays, the air quality is deteriorating, and the indoor air quality is deteriorating due to the high indoor carbon dioxide concentration caused by the long-term closed doors and windows and the operation of the air conditioner, which leads to a decrease in indoor comfort, and it is easy to cause nausea, dizziness, lack of energy and other adverse symptoms. In order to solve the indoor air problem and improve the quality of home life, fresh air conditioners have also emerged as the times require. The emergence of fresh air conditioners has solved the problem of indoor air quality in closed spaces, but there a...
