Split type air-conditioning indoor unit

Abstract

The invention discloses a split type air-conditioning indoor unit, which can realize exchange of indoor air and outdoor air through a pipeline to achieve the exchange of the indoor air. The split type air-conditioning indoor unit comprises a shell with a main base and a front framework, a heat exchanger and a cross-flow fan, the shell is provided with an air outlet and an air inlet, an air duct is formed between the air outlet and the air inlet, the heat exchanger and the cross-flow fan are arranged in the air duct, the air-conditioning indoor unit also comprises a first air pump and a second air pump, and the pipelines of the first air pump and the second air pump are communicated with the indoor and the outdoor for exchange of the indoor air. By adopting the structure, indoor contaminated air can be pumped outdoors through the first air pump, outdoor fresh air can be pumped indoors through the second air pump, the indoor air can be exchanged effectively, the indoor oxygen content can be increased, the indoor carbon dioxide concentration can be reduced, the contamination of the indoor air can be avoided, and the bacterial growth can be inhibited.

Description

technical field [0001] The invention relates to an air conditioner, in particular to a split type air conditioner indoor unit capable of realizing the function of exchanging air in the room. Background technique [0002] An air conditioner is an artificial indoor climate control device, the main components of which include a refrigeration cycle system including a compressor, a condenser, a throttling device, and an evaporator, and an air cycle system including a blower, an air duct, and an air inlet and outlet. The air conditioner absorbs indoor air, changes its temperature through the evaporator and condenser of the heat exchange device, and then discharges it back into the room to achieve cooling or heating and dehumidification, so as to provide people with a fresh and comfortable indoor air environment. [0003] Generally speaking, air conditioners can be roughly divided into integral air conditioners and split air conditioners. The integral air conditioner packs all the...

Problems solved by technology

[0032] In the prior art, due to the long-term cooling or heating of the air conditioner, the indoor air does not circulate, the oxygen content becomes low, and the carbon dioxide content continues to increase, and it is easy to cause indoor air pollution and bacterial growth, which can easily cause various diseases.
