Embodiment Construction

[0044] figure 1 is a schematic sectional view of an air conditioner indoor unit according to an embodiment of the present invention. see figure 1 The air conditioner indoor unit 100 may include a casing 110, a first air blower 120, a second air blower 130, a refrigeration system 140, a fresh air device, and a controller (not shown) storing a computer program.

[0045] The casing 110 may be provided with a casing air inlet 111 for air to flow in, and a first air outlet 112 and a second air outlet 113 for air to flow out. Wherein, the casing air inlet 111 can be opened on the rear wall of the casing 110 , and the first air outlet 112 can be opened on the front wall of the casing 110 .

[0046] The first air blower 120 and the second air blower 130 can be arranged in the casing 110, and are configured to inhale air from the surrounding environment of the air inlet 111 of the casing and impel the air to the first air outlet 112 and the second air outlet respectively. 113 flows....

Abstract

The invention provides a control method for an air conditioner indoor unit and the air conditioner indoor unit. The air conditioner indoor unit comprises a first air supplying fan, a second air supplying fan, a first heat exchanger, a second heat exchanger and a fresh air device, wherein the first heat exchanger is arranged on an air inlet flow path of the first air supplying fan, the second heatexchanger is arranged on an air inlet flow path of the second air supplying fan, and the fresh air device conducts flow guiding on outdoor air to the upstream position of the second heat exchanger. The control method comprises the steps that the outdoor ambient temperature and the indoor ambient temperature are obtained; whether the indoor ambient temperature is closer to the temperature expectedby a user than the outdoor ambient temperature or not is judged; if yes, the fresh air device is started, the temperature of the second heat exchanger is lower than that of the first heat exchanger when the first heat exchanger and the second heat exchanger are in a refrigeration state; and when the first heat exchanger and the second heat exchanger are in a heating state, the temperature of the second heat exchanger is higher than that of the first heat exchanger, the outdoor air is fully subjected to heat exchange, and the temperature difference between an air flow blown by a first air outlet and an air flow blown by a second air outlet is decreased.

Description

technical field [0001] The invention relates to the field of air conditioning, in particular to a control method for an air conditioner indoor unit and the air conditioner indoor unit. Background technique [0002] In order to avoid air quality problems such as high carbon dioxide concentration caused by poor ventilation in the indoor environment, a fresh air device connected to the outdoor environment is usually added in the indoor unit to introduce outdoor air into the indoor environment. However, there is a technical problem that there is a temperature difference between the outdoor air temperature and the body temperature in the air-conditioning indoor unit with the fresh air device at present, which causes the user to feel uncomfortable. Considering comprehensively, a control method for an air-conditioning indoor unit with a fresh air device and an air-conditioning indoor unit for comfortable air supply are required in design. Contents of the invention [0003] An ob...
