Embodiment Construction

[0019] The invention provides a power supply method for an air-conditioning chiller, which uses a direct-current amplitude piezoelectric to supply power to a frequency converter and a PLC controller of the chiller, and uses three-phase alternating current to supply power to a refrigerant water pump of the chiller. The frequency converter inverts the direct current amplitude piezoelectric power into three-phase alternating current to drive the compressor of the frequency converter of the chiller to work.

[0020] Specifically, such as figure 1 As shown, the embodiment of the present invention provides an air-conditioning chiller, which adopts the above-mentioned power supply method for the air-conditioning chiller. The air conditioner chiller includes a DC amplitude piezoelectric power supply 11, a frequency converter 12, a compressor 13, a PLC controller 14, a unit load 15, a three-phase AC power supply 21, a start controller 22, a refrigerant water pump 23, and a first filter...

Abstract

The invention discloses a power supply method for an air conditioning chiller, an air conditioning chiller and an air conditioner. The power supply method for the air conditioning chiller comprises steps: DC amplitude piezoelectricity is adopted to provide power for a frequency converter and a PLC of the chiller; and three-phase AC is adopted to provide power for a coolant water pump of the chiller. The power supply method for the air conditioning chiller has the advantages of simple power supply structure and electric energy conservation.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a power supply method for an air conditioner chiller, an air conditioner chiller and an air conditioner. Background technique [0002] Frequency conversion technology has been widely used in various electromechanical equipment. Marine air-conditioning chillers are composed of fully enclosed scroll compressors, plate evaporators, condensers, throttling structures, electrical control boxes, frequency converters, etc., and integrated refrigerant water pumps. The frequency conversion compressor is adopted to maintain a high energy efficiency ratio in the whole range of working conditions, and the energy saving performance is superior. [0003] For mobile vehicles such as ships, two power sources are usually provided, one is the three-phase AC power generated by the engine, and the other is the DC amplitude piezoelectric power provided by the energy storage device. In the prior art, t...
