Book Description
The thermal performance of a three-ton, air-to-air heat pump was evaluated in the laboratory under steady-state (no frost) and frosting conditions. In both cases, the heating capacity and the coefficient of performance were computed. During frosting conditions, there was a significant decrease in the outdoor airflow rate through the outdoor coil and this resulted in the decrease in the heating capacity and the coefficient of performance. The results of the experimental evaluation indicate the importance of considering the effect of frost accumulation on the outdoor coil. There may be a significant reduction in thermal performance when the outdoor conditions result in substantial formation of frost on the coil and fins of the outdoor unit. The characteristic curves of both fan-motor units indicate that improvement of the efficiency of these units would reduce the operating costs during the life of the heat pump system with a relatively small increase in the fan-motor unit first cost.
