Are heat recovery coils installed in the outside air and exhaust ducts for air handler 3?

Heat recovery coils are designed to enhance the efficiency of HVAC systems by transferring heat from exhaust air to incoming outside air, thereby reducing the energy needed to heat or cool the air being circulated in a building. When considering the installation of heat recovery coils in specific ducts associated with an air handler, it is crucial to understand the overall design intention and function.

In this scenario, stating that heat recovery coils are installed in both the outside air and exhaust ducts indicates a comprehensive approach to energy efficiency. By incorporating heat recovery in both duct types, the system can maximize thermal exchange, allowing for the pre-conditioning of outside air using the warmth from the exhaust air. This method significantly improves energy conservation and overall system performance, particularly in climates with high variance in temperature.

The correct choice reflects this dual installation, promoting energy efficiency by utilizing a holistic approach to heat recovery. Therefore, the answer confirms that heat recovery coils are indeed placed in both the outside air and exhaust ducts for air handler 3, functioning synergistically to reduce energy consumption and enhance comfort within the space.
