What are the common faults of air conditioning compressor repair

Presumably everyone is also curious about the cooling effect of the air conditioner. In fact, all this is the credit of the compressor. The principle is that the compressor extracts the refrigerant from the low-pressure area, compresses it, and sends it t器2䀀

Advantages of adding economizer to screw chiller

The temperature control range of the standard screw chiller is 3～35℃, and the efficiency is significantly reduced when operating under lower temperature conditions. In order to meet the temperature requirements of more industries for chillers, make the single-stage screw compressor work according to the two-stage refrigeration cycle and achieve the effect of energy saving, an economizer can be added to the unit.
