INTRODUCTION: HVAC BASICS

← Back to document page

The cooling coils are fed from a source of cooling, such as chillers, a cooling tower, or DX unit. The refrigerant enters the cooling coils, absorbs heat from the passing air, and returns to its source to desorb the heat that it took in. The heating coils are fed from a heat source such as a boiler or electricity.
