Spread idea to carry the cover look and feel throughout the brochure Save energy in industrial cooling and air conditioning processes Improving efficiency and reducing energy consumption is key in today’s air-conditioning and refrigeration systems. Often systems are designed and optimized to operate at full load conditions or with fixed condensing pressures, and at these conditions both conventional and electronic control valves operate efficiently. However, under a partial load condition or varying condensing pressure (e.g. due to low ambient temperature) the condensing pressure decreases. Under...

Electrical control valve applications The refrigeration circuit in the figure on the back page demonstrates how the same type of control valve can be used for different tasks: expansion valve for superheat control, suction pressure control for capacity modulation, liquid injection for de-superheating of compressor, condensing pressure control for head pressure control and hot gas bypass control to compensate excess compressor capacity and to ensure evaporating pressure does not go below a setpoint. The same valve can be used for all conventional refrigerants (R-22, R-134a, R-407C, R-404A, R-507,...
