Problems solved by technology

[0003] Although this type of method has a certain defrosting effect, it ignores the user's experience. For users, they are most concerned about the heating and heating effect of the air conditioner and the comfort brought by the air conditioner when it is running. The above defrosting method is only Considering the operating status of the air condi

Example Embodiment

[0033] It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other if there is no conflict.

[0034] Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.

[0035] Such as figure 1 The defrosting process of the air conditioner is shown, and the corresponding defrosting method is as follows:

[0036] Detect the pressure value of the air conditioner heating high-pressure pressure sensor, and obtain the corresponding saturation temperature value Pd_t according to the pressure value; the saturation temperature value can be obtained by querying the pressure-saturation temperature table, which is summarized by the engineer based on actual experience;

[0037] Obtain the outdoor ambient temperature Tao of the air conditioner;

[0038] Detect the outdoor unit temperature Tdef of the air conditioner; there are many objects corresponding to the...

Abstract

The invention provides a defrosting method of an air conditioner. The method comprises the following steps: detecting the pressure valve of a heating high-pressure pressure sensor of the air conditioner; obtaining the corresponding saturated temperature value Pd_t according to the pressure value; obtaining the outdoor side ambient temperature Tao of the air conditioner; detecting the external unittemperature Tdef of the air conditioner; and judging whether the saturated temperature value Pd_t, the external unit temperature Tdef and the outdoor side ambient temperature Tao meet defrosting conditions or not, and if yes, entering a defrosting mode. Compared with the prior art, the defrosting method has the advantages that the defrosting mode can be started at a proper time point, accurate defrosting is carried out, the defrosting effect is improved, and the use comfort of users is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a defrosting method for an air conditioner. Background technique [0002] At present, air conditioners, as people's daily necessities, have entered thousands of households. However, due to the influence of temperature, air conditioners need to perform defrosting procedures when they are running in winter. In order to achieve a good defrosting effect, many air conditioner manufacturers in the industry have adopted different detection and defrosting methods, but these methods have one thing in common, that is, they are all based on low-pressure side parameters, such as the temperature detected by the ambient temperature sensor of the external unit and the pressure detected by the low-pressure sensor. Wait to judge whether the air conditioner meets the defrosting conditions, and then decide whether to defrost or not. [0003] Although this type of method has a certain defr...
