Abstract

The invention discloses an air conditioner starting and operating at low voltage and a control method thereof. The air conditioner comprises a compressor, a voltage detection unit, a controller and an electric control component, wherein input voltage is electrically connected with the controller through the voltage detection unit; the controller is electrically connected with the compressor through the electric control component; four binding posts are arranged on the compressor, namely a main winding, a secondary winding, a first common terminal and a second common terminal; and the second common terminal is a tap extending from the main winding of the compressor. When the air conditioner starts, the voltage detection unit detects the input voltage, and an initial operating state of the air conditioner is determined according to the detected input voltage; during operation, the voltage detection unit detects the input voltage, and operation switching of the air conditioner is determined according to the detected input voltage when the voltage greatly fluctuates, namely the first common terminal is connected / disconnected with the second common terminal; and the invention has the characteristic that: the air conditioner can normally and stably start and operate at low voltage and has a wide application range.

Description

technical field [0001] The invention relates to an air conditioner with low voltage start-up operation and a control method thereof. Background technique [0002] At present, in order to stimulate rural consumption, improve people's lives, and promote industry development, the state vigorously promotes the policy of sending home appliances to the countryside; however, in many rural areas in China, the electricity voltage is generally low, the weather is hot, and the air conditioner cannot be turned on. It is difficult to use air-conditioning products with high cost performance and guaranteed service, and it is impossible to enjoy the achievements of economic and social development. [0003] For existing air conditioners, in order to meet the normal fluctuations in the mains supply, when designing the air conditioner, type tests under various working conditions will be carried out; according to the requirements of the national standard GB / T 7725-2004 room air conditioner, in ...
