Abstract

The invention discloses a direct-current variable-frequency air conditioning compressor driving system. The direct-current variable-frequency air conditioning compressor driving system comprises a controller, wherein the controller comprises an external machine control unit, a temperature control unit and a connecting unit; the output end of the connecting unit is provided with an indoor unit, andthe external machine control unit comprises a frequency control unit, a wind power control unit, a key unit and an infrared unit; and the key unit comprises a control PCB and a key current unit, thetemperature control unit comprises a temperature sensor, and a CPU is arranged at the output end of the control PCB. The direct-current variable-frequency air conditioning compressor driving system has the technical effects and advantages that the key current unit is arranged, the temperature sensor is used for detecting the temperature of the outside, and then a detected temperature electric signal is transmitted to the display unit to display discharging, so that the wind power control unit can be controlled through a silica gel key, key position current obtained through pressing of the keycurrent unit is transmitted to the inside of the CPU through the control PCB, and finally the CPU transmits calculated signals to the interior of the indoor unit through the infrared unit.

Description

technical field [0001] The invention relates to the technical field of home appliance control, in particular to a DC inverter air conditioner compressor driving system. Background technique [0002] At present, the competition for home appliance air conditioners is becoming increasingly fierce, and the technical requirements for products are constantly improving, such as requiring products to be environmentally friendly, highly intelligent in controllability, and short in development cycles. However, when controlling the air conditioner compressor, it cannot be guaranteed that the signal from the controller can be completely transmitted to the interior of the indoor unit. [0003] Therefore, it is necessary to invent a DC inverter air conditioner compressor drive system to solve the above problems. Contents of the invention [0004] The purpose of the present invention is to provide a DC variable frequency air conditioner compressor drive system, which uses a temperature ...
