Embodiment

[0013] Example: see figure 1 , 2 , In the frequency conversion refrigerator of this embodiment, the refrigerator display board and the main control board communicate by means of a protocol, and the refrigerator main control board collects the temperature of each room and the environment through a plurality of temperature sensors (refrigerating sensors, freezing sensors, and ambient temperature sensors); The main control board of the refrigerator directly drives the variable-speed fans to run at different speeds through hardware circuits and software; the main control board of the refrigerator transmits the required speed information to the drive board of the variable frequency compressor through the communication protocol, and the drive board of the variable frequency compressor drives the compressor at a specified speed run.

[0014] Set the speed range of the variable frequency compressor as S1-S2, where S1 is the lowest speed and S2 is the highest speed; the speed range of...

Abstract

The invention discloses a frequency-variable refrigerator, which comprises a master control panel, a refrigeration sensor, a freezing sensor, an environmental temperature sensor and a variable-speed fan. The refrigerator sensor, the freezing sensor and the environmental temperature sensor are connected with the master control panel, a variable-frequency compressor driving plate is connected with the master control panel and a power source, and a variable-frequency compressor is connected with the variable-frequency compressor driving plate. The master control panel controls the variable-frequency compressor and the variable-speed fan to enter different running modes after comprehensive analysis and computation according to temperatures detected by the various sensors and instructions transmitted by a display panel, and the refrigerator can effectively assuredly quickly achieve the optimal running state under various working conditions.

Description

Technical field: [0001] The invention relates to a frequency conversion refrigerator and a control method thereof. Background technique: [0002] The existing frequency conversion refrigerator mainly considers the speed control of the frequency conversion compressor, but now the refrigerator has gradually started to apply the variable speed fan and the frequency conversion compressor at the same time. At present, there is no one that comprehensively considers the speed of the variable speed fan and the frequency conversion compressor under different conditions. Specific control methods. Invention content: [0003] In order to overcome the defects of the prior art, the object of the present invention is to provide an inverter refrigerator and its control method. The main control board controls the inverter compressor, The variable-speed fan enters different operating modes, effectively ensuring that the refrigerator can quickly reach the best operating state under various ...
