Low-power-consumption electric equipment, electricity utilization system and power supply method and device of electric equipment

Abstract

The invention relates to low-power-consumption electric equipment, an electricity utilization system and a power supply method and device of the electric equipment. The electric equipment comprises anelectricity utilization unit which is used for working after being powered and generating heat energy during working; a thermoelectric conversion unit which is used for converting the heat generatedby the electricity utilization unit into electric energy and storing the electric energy; a control unit which is used for controlling the thermoelectric conversion unit to supply power to the electric equipment when the electric energy stored in the thermoelectric conversion unit is greater than a first threshold value and controlling a power supply input end to be accessed to a power supply to supply power to the electric equipment when the electric energy stored in the thermoelectric conversion unit is less than a second threshold. According to the invention, the thermoelectric conversion unit converts heat energy dissipated by the electricity utilization unit into electric energy for reuse by electric equipment; the problem that the operation stability is influenced due to the temperature rise of the electric equipment caused by long-term operation of the electric equipment is solved, and reduction of the power consumption cost of the electric equipment is facilitated; the power consumption is reduced; and the economic pressure of a user is reduced.

Description

technical field [0001] The invention relates to the technical field of power supply control, in particular to a low-power consumption electrical equipment, an electrical system, and a power supply method and device for the electrical equipment. Background technique [0002] The traditional air-conditioning system controller is directly powered by the power supply. During the long-term operation of the air-conditioning system, the power consumption is huge, which puts huge economic pressure on many air-conditioning users. The air conditioner controller is generally powered by AC-DC power supply or DC-DC, etc. During the operation of the air conditioner controller, part of the electric energy input from the power supply is used by the controller as active power, and part of it will be used in the form of reactive power and heat energy. Consumed; on the one hand, this part of the heat energy brings a certain bottleneck problem to the normal development of the controller, on the...

Problems solved by technology

The air conditioner controller is generally powered by AC-DC power supply or DC-DC, etc. During the operation of the air conditioner controller, part of the electric energy input from the power supply is used by the controller as active power, and part of it will be used in the form of reactive power and heat energy. Consumed; on the one hand, this part of the heat energy brings a certain bottleneck problem to the normal development of the controller, on the other hand, in order to ensure the stable operation of the controller, it is necessary to perform additional heat dissipation treatment on the controller, which undoubtedly increases the controller’s cost
