Problems solved by technology

There are several disadvantages in this: first, the energy consumption is relatively large due to turning to defrosting through the four-way valve; second, the continuous operation time of the fixed preset compressor is not scientific enough, which may easily lead to premature defrosting and affect the heating performance; Third, it is not possible to judge the conditions for stopping defrosting more reasonably

Embodiment

[0027] Such as figure 1 As shown, the air conditioner defrosting method according to the embodiment of the present invention includes the following steps:

[0028] S1, the outdoor ambient temperature Ta is detected by the first temperature sensor, and the defrost tube temperature Tb is detected by the second temperature sensor.

[0029] S2, detecting the continuous running time M of the compressor, judging whether the continuous running time M of the compressor is greater than or equal to the first set time M1, if yes, proceed to step S3; if not, continue to detect the continuous running time M of the compressor.

[0030] S3, judging whether the defrosting tube temperature Tb is less than or equal to the first set temperature Tc, if yes, proceed to step S4; if not, continue to detect the defrosting tube temperature Tb.

[0031] S4, judging whether the outdoor ambient temperature Ta is greater than the second set temperature Td and lower than the third set temperature Te, if y...

Abstract

The invention discloses a defrosting method of an air conditioner. The defrosting method is characterized by including: S1, detecting temperature Ta of outdoor environment and temperature Tb of a defrosting pipe; S2, detecting continuous running time M of a compressor, and judging whether the continuous running time M of the compressor is greater than and equal to first set time M1 or not; S3, judging whether temperature Tb of the defrosting pipe is lower than or equal to first set temperature Tc; S4, judging whether the temperature Ta is higher than second set temperature Td and lower than third set temperature Te or not; S5, stopping the compressor, and controlling a fan of an outdoor unit to run for defrosting; S6, judging whether the temperature Ta is lower than or equal to the secondset temperature Td or not; S7, controlling a four-way valve of the air conditioner to turn for defrosting; S8, when the temperature Tb is greater than or equal to fourth set temperature Tf and lastingtime is greater than second set time M2, finishing defrosting. The defrosting method has the advantage that energy consumption of the air conditioner during heating is lowered.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner and a defrosting method for the air conditioner. Background technique [0002] When the air conditioner is running for heating and the refrigerant evaporates, the temperature of the refrigerant flowing through the heat exchanger of the outdoor unit decreases, resulting in frosting on the outdoor heat exchanger. The frosting on the outdoor heat exchanger will seriously affect the heating performance of the air conditioner. The defrosting methods of the existing air conditioners all judge whether to enter the defrosting after setting the continuous running time of a compressor and meeting certain conditions. After entering the defrosting, the four-way valve changes direction to perform defrosting; After completion, the four-way valve turns again and re-enters the heating state. There are several disadvantages in this: first, the energy consumption is re...
