Variable frequency drives play a key role in any energy management plan. A variable frequency drive is used to vary the speed of motors that drive fans, pumps and other equipment in relation to changing heating and cooling requirements. By modulating the speed of the controlled motor the motor will consume less power at lower speeds.  In addition, reduced exhaust air flow will result in reduced heat loss, make up air flow and ultimately reduced heating and air conditioning requirements. This system allows variable frequency drives to improve comfort while reducing energy consumption and costs.

Heat recovery is a method of re-claiming lost heat.  When warm air is exhausted from a building it is wasted and must be reheated, unless it is reclaimed.  Reclaiming this heat can be done in a number of ways.  One way is to place a heat exchanger in the air flow of the exhaust and a heat exchanger in the make up air flow entering the building.  When water or glycol is pumped through a piping system from the exhaust air heat exchanger to the make up air heat exchanger the heat exhausted is absorbed by the water or glycol and then circulated to the make up air heat exchanger where it is reclaimed through absorption.  In this way the make up air that enters the building is heated, saving energy as well as heating costs.
