Embodiment Construction

[0038] like Figure 1-3 As shown, the present invention provides a control method for a double cross-flow air conditioner, which includes:

[0039] The double cross-flow air conditioner includes a first cross-flow fan and a second cross-flow fan, and also includes a first motor 11 for driving the first cross-flow fan and a first motor 11 corresponding to the first cross-flow fan. The air outlet 21, and the second motor 12 for driving the second cross-flow fan and the second air outlet 22 corresponding to the second cross-flow fan, the first air outlet 21 is arranged at the second outlet Above the tuyere 22;

[0040] The detection step is used to detect the indoor ambient temperature t and detect whether the double cross-flow air conditioner is in the cooling mode or the heating mode;

[0041] The judging step is used to judge whether the relationship t is satisfied between the indoor ambient temperature t and the preset temperature value T0 after the air conditioner is turne...

Abstract

The invention provides a control method for a double-throughflow air conditioner. The control method comprises a detection step, a judgment step and a control step. The detection step is used for detecting indoor environment temperature t and for detecting whether the double-throughflow air conditioner is in a refrigeration mode or a heating mode. The judgment step is used for judging whether theindoor environment temperature t and a preset temperature value T0 meet the relation that t1 error<|t-T0|<=t2 error after the air conditioner is started for preset time. According to the control step,when t1 error<|t-T0|<=t2 error, the rotation speed N1 of a first motor is controlled to be N1max, the rotation speed N2 of a second motor is controlled to be N2min, or the rotation speed N1 of the first motor is controlled to be N1min, the rotation speed N2 of the second motor is controlled to be N2max, wherein N1max is the preset maximum rotation speed of the first motor, N2max is the preset maximum rotation speed of the second motor, N1min is the preset minimum rotation speed of the first motor, and N2min is the preset minimum rotation speed of the second motor. Through the control method,on the premise that the requirement of a room load is met, air-feeling-free air supply enjoyment is really brought to a user, and the comfort level of a human body is increased.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a control method of a double cross-flow air conditioner. Background technique [0002] The traditional existing air-conditioning indoor unit has a long temperature rise time during cooling / heating, and cannot quickly reach the specified indoor temperature. When the indoor unit is cooling, it will blow to the human body, resulting in poor human feeling; and when the indoor unit is heating, the hot air tends to Going up causes the hot air in the upper part of the room to fail to land, resulting in energy waste and reduced human comfort; insufficient air volume of the indoor unit leads to low cooling and heat, and the room load cannot meet user requirements. [0003] Due to the long temperature rise time of the indoor unit of the air conditioner in the prior art during cooling / heating, the indoor unit will blow to the human body when the indoor unit is cold, res...
