Problems solved by technology

[0002] In cold areas, especially in snowy weather in winter, the chassis and condenser of the external unit of the air conditioner will freeze. When the ice layer reaches a certain thickness, it will hinder the operation of the fan blades, causing the unit to be abnormal and unable to start and work normally.
At the same time, the condens

Example Embodiment

[0051] Example 1

[0052] like figure 1 , 2 , 5 and 6, the present invention proposes a control method for an air conditioner, the air conditioner includes a de-icing pipeline system 3, the de-icing pipeline system 3 is close to the chassis 4 of the air conditioner, and the de-icing pipeline system 3 is connected to the air conditioner. The compressor 5 of the device is connected;

[0053] The control method includes the following steps:

[0054] S1 obtains the icing condition of chassis 4;

[0055] In S2, when the chassis 4 freezes, the compressor 5 generates high-temperature refrigerant, and controls the high-temperature refrigerant to flow to the chassis 4 through the deicing pipeline system 3, and the chassis 4 is de-iced until the chassis 4 is de-iced.

[0056] In this embodiment, when the air conditioner is turned on and it is detected that the chassis 4 of the air conditioner freezes, the air conditioner starts the deicing procedure for the chassis 4, the compressor...

Example Embodiment

[0074] Embodiment 2

[0075] As with the above-mentioned control method for an air conditioner, this embodiment differs from it in that when the chassis temperature > the preset temperature T 1 and condenser temperature > preset temperature T 3 control the air conditioner to heat normally.

[0076] In this embodiment, when it is detected that the chassis temperature > preset temperature T 1 It indicates that the chassis 4 is not frozen at this time, and the air conditioner does not need to perform the ice-melting treatment of the chassis 4, and further, the temperature of the condenser is detected and judged, if it is judged that the temperature of the condenser is less than or equal to the preset temperature T 3 At this time, the condenser needs to be de-iced. The compressor 5 generates high-temperature refrigerant and discharges it to the condenser through the four-way valve, so as to de-icing the condenser. If it is determined that the condenser temperature is greater tha...

Example Embodiment

[0078] Embodiment 3

[0079] The control method for an air conditioner as described above, the difference between the present embodiment and the method is that, when deicing the chassis 4, the method further includes:

[0080] S110 detects the chassis temperature when chassis 4 is melting ice;

[0081] Chassis temperature and preset temperature T when S120 de-ices chassis 4 2 Compared;

[0082] S130 chassis 4 when the chassis temperature reaches the preset temperature T 2 And the chassis temperature when the chassis 4 melts ice reaches the preset temperature T 2 duration of up to t 1 At the end of the thawing of chassis 4.

[0083] In this embodiment, by detecting the temperature of the chassis when the chassis 4 is defrosted, and comparing it with the preset temperature T 2 Make a comparison to judge whether the chassis 4 has finished melting ice, and when the chassis 4 is melting ice, the chassis temperature reaches the preset temperature T 2 , and the state lasts for...

Abstract

The invention provides a control method of an air conditioner and the air conditioner. The air conditioner includes a deicing pipeline system, the deicing pipeline system is close to a base plate of the air conditioner, and the deicing pipeline system is connected with a compressor of the air conditioner. The control method includes the following steps that the freezing condition of the base plateis obtained; and when the base plate freezes, the compressor generates a high temperature refrigerant and controls the high temperature refrigerant to flow to the base plate through the deicing pipeline system, and the base plate is deiced until deicing of the base plate is finished. According to the control method of the air conditioner and the air conditioner, the safety degree of deicing of the base plate of the air conditioner can be improved, the electric leakage condition during deicing is prone to being caused, and reliability is good.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner control method and the air conditioner. Background technique [0002] In cold regions, especially in snowy weather in winter, the chassis and condenser of the external unit of the air conditioner will freeze. When the ice layer reaches a certain thickness, it will hinder the operation of the fan blades, causing the unit to be abnormal and unable to start and work normally. At the same time, the condenser is frosted, and the system will enter defrosting after a period of time after starting up, which will affect the customer experience. At present, common air conditioner manufacturers add electric heating belts to the chassis to preheat the unit to melt ice. This solution is not safe, and it is easy to cause leakage and reliability. Contents of the invention [0003] In view of this, the present invention aims to propose a control method of an air co...
