Control method for double-throughflow air conditioner

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...

AI Technical Summary

Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the defects in the prior art that the air-conditioning indoor unit blows to the human body when it is cooling, and the hot air cannot fall to the ground when the indoor unit is heating up, resulting in low comfort for the human body, thereby providing a Control method of double cross-flow air conditioner
