Why the air conditioner does not cool

The cooling load is overloaded or the space is too large, the number of air conditioners is not correct; improper installation will cause poor air circulation, resulting in poor cooling effect; when the freon in the air conditioner is insufficient, it will cause the cooling effect of the air conditioner to deteriorate; the air conditioner is not on time Do cleaning and maintenance, etc.

Design steps of two-wire AC current transmitter

Known high-current current transformers convert different currents into 0~5A alternating current for on-site display. For long-distance transmission, the current must be converted into a standard DC current signal of 4-20mA before transmission.
