Abstract

The invention relates to a PTC electric heating power compensation method and system and an air conditioner. The PTC electric heating power compensation method comprises the steps: detecting power actually consumed by PTC electric heating under corresponding environment temperature according to a preset period; calculating difference value between the actually consumed power and power consumed according to a PTC electric heating theory under the corresponding environment temperature; and increasing air quantity passing through a PTC according to the difference value so as to compensate the power actually consumed by the PTC electric heating. The larger power attenuation difference between the power actually consumed by the PTC electric heating of the air conditioner and power consumed by unaged electric heating is, the faster rotating speed of an air conditioner fan is, and the larger the power compensation of the PTC electric heating of the air conditioner is until the maximum value is achieved. According to the PTC electric heating power compensation method and system and the air conditioner, few devices are used, a circuit is simple, the power compensation for the PTC electric heating of the air conditioner can be realized quicklyat low cost, the heating effect is strengthened, and meanwhile, the reliability, the safety and the user experience of the air conditioner are improved.

Description

technical field [0001] The invention relates to the technical field of air-conditioning electric heating, in particular to a power compensation method, system and air-conditioning device for PTC electric heating. Background technique [0002] PTC ripple heater is a self-controlled temperature heater with automatic constant temperature, power saving and high safety. Due to the durability of PTC electric heating, that is, the power of PTC electric heating will decay with the use time. For example: within 1000 hours of use, the power of PTC electric heating will decay to 90%-95% of the rated value. When electric heating is used, its heating effect will become worse with time, and the longer the time, the more obvious the attenuation. At present, household air conditioners use electric heating mostly PTCR heat-sensitive ceramic elements, which are composed of several single-piece combinations and corrugated heat-dissipating aluminum strips bonded by high-temperature glue. It ha...
