Core Functions in HVAC Systems

The roles of condenser and evaporator coils depend on the system’s operation mode:

Evaporator Coil (Cooling Mode):

Located indoors (typically in air handlers or furnaces), the evaporator coil acts as a heat absorber. Low-pressure, low-temperature liquid refrigerant flows through the coil, where it absorbs heat from the warm indoor air (blown over the coil by a fan). This heat causes the refrigerant to evaporate into a gas, cooling the air, which is then circulated back into the space.

Condenser Coil (Cooling Mode):

Found outdoors (in split-system AC units or heat pump outdoor units), the condenser coil releases heat. The high-pressure, high-temperature refrigerant gas (from the compressor) flows through the coil, where it loses heat to the outdoor air (aided by a fan). This causes the refrigerant to condense back into a liquid, which is then sent back to the evaporator to repeat the cycle.

Tube Material:

Copper: Most common due to excellent thermal conductivity, corrosion resistance, and malleability (easily formed into coils).

Aluminum: Used in some systems for lower cost and lighter weight, though less conductive than copper.

Stainless Steel: Rare, but used in harsh environments (e.g., coastal areas with salt exposure) for superior corrosion resistance.

Fins:

Thin metal fins (usually aluminum) are attached to the tubes to increase the surface area for heat exchange. Fins are often "louvered" or "corrugated" to disrupt airflow, enhancing heat transfer by reducing boundary layer resistance.

Applications

Residential HVAC: Split-system ACs, heat pumps, and packaged units use these coils to condition air in homes.

Commercial HVAC: Rooftop units, chillers, and air-handling units (AHUs) rely on larger coils to cool/heat offices, malls, and industrial spaces.

Specialized Systems: Refrigeration units (e.g., walk-in coolers) and automotive HVAC also use similar coil designs, though scaled for their specific heat loads.
