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 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 poor reliability.

Embodiment 1

[0052] Such as figure 1 , 2 , 5 and 6, the present invention proposes a control method for an air conditioner, the air conditioner includes an ice melting pipeline system 3, the ice melting pipeline system 3 is close to the chassis 4 of the air conditioner, the ice melting pipeline system 3 and 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 the chassis 4;

[0055] 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 deices the chassis 4 until the deicing of the chassis 4 is completed.

[0056] In this embodiment, when the air conditioner is turned on and the chassis 4 of the air conditioner is detected to be frozen, the air conditioner starts the deicing program to the chassis 4, the compressor 5 of the air con...

Embodiment 2

[0075] As the above-mentioned control method of an air conditioner, the difference of this embodiment is that when the temperature of the chassis>the preset temperature T 1 And the 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 shows that the chassis 4 is not frozen at this time, and the air conditioner does not need to perform ice-thawing treatment on the chassis 4, and then detect and judge the temperature of the condenser, if it is determined that the temperature of the condenser ≤ the preset temperature T 3 , the condenser needs to be deiced. The compressor 5 generates high-temperature refrigerant and discharges it to the condenser through the four-way valve, so as to deice the condenser. If it is determined that the condenser temperature is greater than the preset temperature T 3 Then the condenser is not frozen at thi...

Embodiment 3

[0079] As the above-mentioned control method of an air conditioner, the present embodiment is different from it in that, when the chassis 4 is deiced, it also includes:

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

[0081] S120 chassis temperature and preset temperature T when chassis 4 is deiced 2 Compared;

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

[0083] In this embodiment, by detecting the temperature of the chassis when the chassis 4 is deiced, and comparing it with the preset temperature T 2 By comparison, it is judged whether the chassis 4 is deiced, and when the chassis 4 is deiced, the temperature of the chassis reaches the preset temperature T 2 , and the duration of this state also reaches t 1 , it indicates that the chas...

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.
