Abstract

The invention provides a method and circuit for judging a running state of a compressor. Wiring of the circuit is easy, extra wiring is not needed, and the compressor is connected with a contactor ora relay. The circuit is characterized in that at least two diodes which are reversely arranged and connected in parallel are connected between a power input end S1 and a power input end S2, the powerinput end S1 is connected to a power output end A1, the power input end S2 is connected with a coil of the contactor or the relay and then connected to a power output end A2, the power output end A1 and the power output end A2 are connected to a sampling circuit, the sampling circuit is used for collecting output voltage, voltage collecting ends of the sampling circuit are a voltage collecting endB1 and a voltage collecting end B2, and the running state of the compressor is judged by collecting voltage between the voltage collecting end B1 and the voltage collecting end B2.

Description

technical field [0001] The invention relates to the technical field of air conditioner compressor control, in particular to a method and circuit for judging the running state of a compressor. Background technique [0002] In the field of air conditioning, the compressor control panel will make corresponding actions according to whether the compressor is running, such as changing the opening of the electronic expansion valve, calculating the running time, etc. [0003] In the prior art, an external start-up signal is used to confirm the running state of the compressor through the start-up signal. In the prior art, the customer needs to connect the compressor control contactor and also connect the compressor’s start-up signal line, which causes the customer’s Wiring is complicated, causing inconvenience to the scene. [0004] At present, there are several methods to detect the operating status of the compressor on the market: [0005] a. Receive the status signal sent by the...
