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.

Analysis of the circuit diagram of the two compressors' phase failure protection

Analysis of the circuit diagram of the two compressors' phase failure <br><br> Air compressor phase failure <br><br> circuit In the figure, KP is the electrical contact pressure gauge Ai is the CD4073 AND gate circuit, Az is the ~D4025 NOR gate circuit, and A3 is the CD4071 OR gate circuit. The 7806 three-terminal fixed integrated voltage regulator is used as the control circuit for the DC working power supply. When the AC power fails, the relay KA is released and the motor stops.

Refrigerant used by Emerson Copeland compressor

With the global emphasis on environmental protection, our refrigeration industry is also the same, and gradually use some environmentally friendly refrigerants. Previously, the refrigerant used by Emerson Copeland compressors was R22, and R22 was not an environmentally friendly refrigerant. Later, Emerson Copeland Compressors gradually changed the compressors to use environmentally friendly refrigerants.
