Embodiment Construction

[0045] figure 1 It is a schematic cross-sectional view of an air conditioner indoor unit 100 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, an indoor heat exchanger 140, a fresh air device, and a controller (not shown in the figure) storing a computer program.

[0046] The casing 110 may be provided with a casing air inlet 111 for gas to flow in, and a first air outlet 112 and a second air outlet 113 for gas to flow out. 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.

[0047] The first air blower 120 and the second air blower 130 may be arranged in the casing 110 and configured to suck air from the surrounding environment of the air inlet 111 of the casing and force the air to the first air outlet 112 and the second air outlet respectively 113 flo...

Abstract

The invention provides a control method for an indoor unit of an air conditioner and the indoor unit of the air conditioner. The indoor unit of the air conditioner comprises a machine shell, a first air supply fan, a second air supply fan, an indoor heat exchanger and a fresh air device, wherein the first air supply fan and the second air supply fan are arranged in the machine shell, the indoor heat exchanger is arranged on the air inlet flow path of the first air supply fan and the second air supply fan, the fresh air device is used for guiding outdoor air to the upstream of the indoor heat exchanger, and the distance of a fresh air outlet of the fresh air device from an air inlet of the first air supply fan is larger than the distance from the air inlet of the second air supply fan. Thecontrol method comprises the following steps that when the indoor heat exchanger works, outdoor environment temperature and indoor environment temperature are obtained; whether the indoor environmenttemperature is closer to the user expected temperature is judged; if yes, the fresh air device is started, and the rotating speed of the first air supply fan is enabled to be larger than the rotatingspeed of the second air supply fan; if not, the fresh air device is started, the rotating speed of the first air supply fan is enabled to be smaller than the rotating speed of the second air supply fan, so that comfortable air supply is achieved, and electric energy is saved.

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 an 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 to the indoor unit to introduce outdoor air into the indoor environment. However, the current air conditioner indoor unit with fresh air device has the technical problem that the temperature difference between the outdoor air temperature and the somatosensory temperature causes discomfort for the user, and the technical problem that it consumes electricity when it is turned on all the year round. Considering comprehensively, there is a need for a control method and an air-conditioning indoor unit for an air-conditioning indoor unit with a fresh air device that can c...
