A pump package with a Variable Frequency Drive (VFD) and chillers with on-off motorized evaporator valves is one of the most effective technologies the HVAC industry has seen in recent years. It is no surprise that more air conditioning cooling systems are using this technology as an efficient way to save energy while maintaining system integrity.
Variable frequency drives adjust the speed of the pump based on the water pressure, as the system demand is reduced and the chillers cycle off closing the water valve, the system water flow is reduced and the water pressure increases. The pump VFD senses this increase in pressure and slows the pump down to get back to the set point pressure. As the pump slows its energy foot print is reduced.
Not only will a VFD save you on energy costs, it should prolong the life span of the pump and motor as well other mechanical components in the water system. With a VFD, the initial power surge and mechanical shock (water hammer) of switching the motor from off to on is eliminated.
