Certified Energy Manager Practice Exam

In the context of the Coefficient of Performance (COP) formula, Qh represents the amount of heat delivered by a heating or refrigeration system. The COP is a measure of the efficiency of the system, calculated as the ratio of useful heating or cooling provided to the work input to the system. Specifically, when dealing with heating applications, Qh quantifies the thermal energy output that is delivered to the heated space or medium. This makes it a critical parameter for evaluating how effectively the system performs its intended function of transferring heat while consuming work energy. Recognizing Qh as the heat delivered provides insight into the performance and efficiency of heating equipment, helping professionals make informed decisions regarding energy management and system design.
