Which of the following are types of distribution system losses?

The identification of conduction, convection, and radiation as types of distribution system losses is accurate due to their roles in the transfer of heat and energy in building systems.

Conduction refers to the process of heat transfer through materials, like walls and ceilings, where energy moves from warmer to cooler areas. This is significant in distribution systems as it impacts how effectively heat is retained or lost in a building.

Convection involves the movement of heat through fluids (air or liquid), where warmer areas rise and cooler areas sink. In HVAC systems, understanding convection helps in evaluating how well air is distributed throughout a space, influencing heating and cooling efficiency.

Radiation is the transfer of heat in the form of electromagnetic waves. This form of heat loss can occur through windows and other surfaces, affecting the overall thermal performance of a building’s envelope.

Recognizing the significance of these three loss types is essential for professionals working in building performance and energy efficiency, as it allows for more effective strategies to minimize energy waste and improve overall system efficiency.
