Air conditioning control

Provide full-capacity modulation for all sizes of direct-expansion A/C system that use R-410A refrigerant with the APR-410 control from Rawal Devices Inc. The control continuously matches A/C system capacity/output to changing load conditions by varying refrigerant flow according to suction pressure, which changes the temperature of air crossing the coils. The control’s designed applications include multiple-evaporator zoning, in which each evaporator conditions a different zone.
