Problems solved by technology

When the cooling and heating effects of the air conditioner are not good, ordinary users do not know what the reason is, making it impossible for users to judge the fault
[0004] Although some air conditioners have a simple refrigerant leakage protection function, when the air conditioner cannot be used normally due to refrigerant leakage, the air conditioner will display a corresponding fault code, indicating that the air conditioner cannot be used due to lack of refrigerant
However, this protection function is relatively simple, and the fault can only be reported after a large amount of refrigerant leaks. At this time, the air conditioner can no longer be used normally; it also affects the user's judgment on the fault
[0005] Since the existing air conditioners cannot accurately know the remaining amount of refrigerant (or leakage) of the air conditioner, the user cannot know in real time that the air conditioner has a refrigerant leakage failure, so it cannot be repaired in time to avoid more serious accidents

Embodiment 1

[0034] The refrigerant leakage display control method of the air conditioner of the present invention is:

[0035] When the refrigerant leakage ≤ 10%, the air conditioner is in normal operation, the electronic control system does not report a fault, and does not display the remaining amount of refrigerant; at this time, if you need to know the remaining amount of refrigerant in the air conditioner, the user can control the to check the current refrigerant volume of the air conditioner.

[0036] When 10%<refrigerant leakage ≤20%, the air conditioner can operate; since the air conditioner has already leaked refrigerant, its cooling and heating effects have declined, and the refrigerant display device will display the remaining amount of refrigerant, reminding the user of refrigerant leakage, and pay attention to repairing the air conditioner Or charge refrigerant; after displaying for a certain period of time, it will automatically switch to the normal display state; or when dis...

Embodiment 2

[0041] That is, in the technical solution of the first embodiment, the remaining amount of refrigerant displayed by the refrigerant display device is replaced by the leakage amount of refrigerant.

[0042] Positive effect of the present invention:

[0043] It is possible to directly check the remaining condition of the refrigerant or the leakage condition of the current air conditioner through the refrigerant display device of the air conditioner. When refrigerant leakage occurs, it can be found in time; if it affects the normal operation of the air conditioner, the hidden danger of refrigerant leakage of the air conditioner can be eliminated in time to avoid subsequent more serious accidents. Therefore, the user complaint rate can be effectively reduced.

[0044] Taking the air conditioner implementing the technical solution of the present invention as an example, the air conditioner has a refrigerant leakage display function. It is displayed as follows:

[0045] 1. When it...

Abstract

The invention discloses an air conditioner with a refrigerant leakage display function. The air conditioner comprises an electric control device and a display device, wherein the electric control device is provided with a detection module, the detection module is provided with a detection component for detecting the operation state of the air conditioner, and the display device is provided with a refrigerant display component for displaying the quantity of remaining refrigerants or leaked refrigerants of the air conditioner. The invention further discloses a display control method of the air conditioner. By means of the technical scheme, the quantity of the remaining refrigerants or the leaked refrigerants of the air conditioner can be displayed in real time, a user can know whether the refrigerants of the air conditioner are leaked according to the display condition, and accordingly faults of the air conditioner caused by leaking of the refrigerants can be prevented in time; more serious accidents are avoided later, and the complaint rate of the user can be effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of air conditioning equipment control. Specifically, the present invention relates to an air conditioner with a refrigerant leakage display function. In addition, the present invention also relates to a refrigerant display control method of the air conditioner. Background technique [0002] During the use of the air conditioner, refrigerant leakage often occurs, which affects the cooling and heating effects. For example, when installing an air conditioner, if the emptying time is too long, the refrigerant will be reduced; if the indoor and outdoor high and low pressure connection pipe nuts are not sealed well, the refrigerant will leak slowly for a long time; Cause refrigerant leakage; etc. If the refrigerant leaks, it will seriously affect the cooling and heating effects of the air conditioner. [0003] In the existing commonly used air conditioners, there is generally no function of automatic detection...
