Abstract

The invention relates to a power factor compensation type comprehensive energy-saving device of an air conditioner and the energy-saving device can carry out power factor compensation to the air conditioner and other inductive loads; in addition, the energy-saving device of the invention further has the functions of no-load automatic shutdown, low temperature limitation of the air conditioner and automatic temperature increase during no activity of the people or sleep, and each function thereof has the energy-saving effect for the air conditioner. The energy-saving device of the invention has very significant energy-saving effect for carrying out the comprehensive energy conservation to the air conditioner.

Description

technical field [0001] The invention relates to an energy-saving device, in particular to a power factor compensation type air-conditioning comprehensive energy-saving device. Background technique [0002] At present, in China, which is developing rapidly, energy shortage has become a national priority. In summer, the power consumption of air conditioners accounts for 30% of the electricity consumption of the whole city; and in household electricity consumption, the power consumption of air conditioners accounts for a very large part. The air conditioner is an inductive load, and its main power consumption is the compressor, followed by two indoor and outdoor electric fans, and their power factors are very low. In order to effectively use energy, the International Electrotechnical Commission (I.E.C) has formulated a series of specifications for the power supply of electrical appliances. IEC-1000 is the specification for harmonic current in power supply, and the power factor...
