Embodiment Construction

[0024] In the following, the air conditioner compressor system and its control method of the present invention will be described in detail with reference to the drawings and specific embodiments.

[0025] Fig. 1 is a schematic diagram of the installation structure of the air conditioner of the present invention, and Fig. 2 is a schematic diagram of the structure of the compressor system of the air conditioner of the present invention.

[0026] As shown in FIGS. 1 and 2 , the air conditioner of the present invention is roughly divided into an outdoor unit 400 and an indoor unit 500 .

[0027] The outdoor unit 400 includes: during the initial operation, the control unit 100 that controls the frequency of the inverter compressor to increase to the set frequency, and operates the inverter compressor; the inverter compressor 200 under the control of the compressor control unit and one or one The above constant speed compressor 300.

[0028] The control unit 100 calculates the pres...

Abstract

The invention discloses an air-conditioner compressor system and its control method, the method is in the early running, limit the inverter compressor frequency until be upgraded to the set frequency, after a specified time, and then operate on the normal frequency. Also include frequency set to initial frequency to start, and up to the limit set frequency, the frequency will be once again reduced to the initial frequency of the process. the said set frequency is 80% of the largest frequency. Its system, including: the inverter compressor can adjust frequency within the normal frequency; have also set up the uniform compressor which start under the load increase; compressor control parts control inverter compressor frequency up to a certain frequency of operation in the early running. The invention through the early start, raising compressor frequency, thus preventing the the phenomenon that household electrical appliances can not start because in preheated state for a long time, and it can quickly reach the normal functioning state and improve the reliability of the products.

Description

technical field [0001] The invention relates to an air conditioner compressor. In particular, it relates to a method of increasing the frequency of the inverter compressor while limiting the frequency to a stable frequency after the initial start-up, preventing the frequency of the inverter compressor from suddenly dropping to a low voltage, and preventing the household appliances from being left at the same time for a long time. The phenomenon of being unable to start due to preheating state can make the product quickly reach the normal operation state and improve the reliability of the air conditioner compressor system and its control method. Background technique [0002] In the existing air conditioner compressor system, in order to control the number of revolutions of the compressor at various speeds, an inverter compressor with excellent cooling power and power consumption is used because no inverter compressor is used. Under the rated voltage of 220V (60Hz), the syste...
