Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: An air-to-air split system residential heat pump of nominal three-ton capacity was instrumented and tested in the heating mode under laboratory conditions. This was the second of a planned series of experiments to obtain a data base of system and component performance for heat pumps. The system was evaluated under both steady-state and frosting-defrosting conditions; sensitivity of the system performance to variations in the refrigerant charge was measured. From the steady-state tests, the heating capacity and coefficient of performance were computed, and evaluations were made of the performance parameters of the fan and fan motor units, the heat exchangers and refrigerant metering device, and the compressor. System heat losses were analyzed. The frosting-defrosting tests allowed the observation of system and component performance under dynamic conditions, and measurement of performance degradation under frosting conditions.
