The utility model provides a floor type air conditioner indoor unit.
In the embodiment of the present invention, as shown in fig. 1 to 3, the floor type air conditioner indoor unit includes a casing 100 and a fresh air component 200.
The housing 100 may be formed by splicing several plates, and an installation cavity is formed therein for installing components such as a heat exchanger and a fan of an indoor unit of an air conditioner. In general, the cross section of the casing 100 may be various shapes such as a circle, an ellipse, a square, a nearly circle, a polygon, etc., and the present embodiment explains the floor type air conditioning indoor unit of the present application in detail with the casing 100 being a cylinder shape.
Specifically, in the present embodiment, the housing 100 has a fresh air inlet 110, a fresh air outlet 120, an indoor air outlet 130 and an indoor air inlet 140. The fresh air component 200 is installed in the housing 100 and includes a heat exchanger 210. The heat exchanger 210 has a fresh air duct 201 and an indoor air exhaust duct 202. One end of the fresh air duct 201 is communicated with the outside through a fresh air inlet 110 on the casing 100, and the other end is communicated with the inside through a fresh air outlet 120 on the casing 100; one end of the indoor air exhaust duct 202 is connected to the outdoor via the indoor air exhaust opening 130, and the other end is connected to the indoor via the indoor air intake opening 140.
Specifically, the heat exchanger 210 may be a total heat exchanger or a sensible heat exchanger. When the heat exchanger 210 is a total heat exchanger, the air flow in the fresh air duct 201 and the air flow in the indoor air exhaust duct 202, that is, the fresh air and the indoor air can exchange temperature and humidity at the same time; when the heat exchanger 210 is a sensible heat exchanger, the fresh air in the heat exchanger 210 and the indoor air exchange only temperature. Thus, no matter the heat exchanger 210 is a total heat exchanger or a sensible heat exchanger, when fresh air is introduced from the outside by the fresh air unit 200, the fresh air exchanges heat with the indoor air in the indoor air exhaust duct 202. Therefore, the fresh air can be precooled or preheated, the comfort of the fresh air is improved, and the user experience is improved.
And because partial indoor air is arranged to the open air, the proportion of the indoor muddy air can be reduced, the fresh air introduced in a matching manner can further improve the freshness of the indoor air, and the comfort level of the indoor environment is improved. Therefore, compared with the existing floor type air conditioner indoor unit, the technical scheme of the application has the advantage of improving the user experience.
