Problems solved by technology

[0002] Traditional air conditioners need to use outdoor temperature sensors to judge whether there is frost and then defrost. For example, the Chinese patent No. ZL03107294. It is the scheduled defrosting built in the program, or the "intelligent defrosting" judged according to some changing factors, such as the Chinese patent No. The defrosting control method of the air conditioner is divided into areas, but there may be common problems such as not being able to enter the defrosting, defrosting is endless, defrosting without frosting, defrosting does not meet the requirements of national standards, and the heating effect is affected by defrosting.

Embodiment Construction

[0047] Below in conjunction with embodiment the present invention is described in further detail.

[0048] The air conditioner of this patent overcomes the traditional shortcomings. The air conditioner is based on the variation of the indoor coil temperature sensor (thermistor), the variation of the ambient temperature, the variation of the indoor wind speed, the accumulated amount of heating operation time, and the outdoor fan And a series of comprehensive factors such as whether the compressor is overloaded or not are used to judge whether the outdoor unit is frosted and whether to defrost. This smart defrost operates according to the following points:

[0049] a) In the case of intelligent defrosting mode, one of the following seven conditions is met (for each small condition, it must be satisfied at the same time to be considered valid) to start defrosting, and the sleep light flashes during defrosting:

[0050] Among them: TE represents the temperature of the indoor coil,...

Abstract

The invention relates to an intelligent defrosting method of an air conditioner. The air conditioner judges whether one of the seven conditions is satisfied according to a series of integral elementssuch as indoor coil pipe temperature transducer variable quantity, environment temperature variable quantity, indoor wind velocity variable quantity, heat-production runtime accumulation quantity, andwhether an outdoor fan and a compressor are overcurrent protected, to determine whether an outdoor set is defrosted or whether defrosting is needed or not, so that intelligent defrosting is performedwithout using an outdoor coil pipe temperature transducer. The outdoor coil pipe temperature transducer and related signal lines are saved on the base of traditional air conditioners. Intelligent defrosting can be performed without human interference and only operation according to a preset program is needed. Clean outdoor defrosting is provided, heat quantity is not affected, and international specified requirements are satisfied.

Description

technical field [0001] The invention relates to an intelligent defrosting method for an air conditioner. Background technique [0002] Traditional air conditioners need to use outdoor temperature sensors to judge whether there is frost and then defrost. For example, the Chinese patent No. ZL03107294. It is the scheduled defrosting built in the program, or the "intelligent defrosting" judged according to some changing factors, such as the Chinese patent No. The defrosting control method of the air conditioner is divided into areas, but there may be common problems such as not being able to enter the defrosting, defrosting is endless, defrosting without frosting, defrosting does not meet the requirements of national standards, and the heating effect is affected by defrosting. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an intelligent defrosting method for an air conditioner in view of the above-mentioned prior...
