Defrost cycle performance for an air-source heat pump with a scroll and a reciprocating compressor.

Type of article: Article, IJR article

Summary

Frost accumulation and defrost tests of a 10.6 kilowatt nominally sized air-source heat pump equipped with a scroll and then with a reciprocating compressor revealed the overall performance of both systems. The system equipped with the scroll compressor provided a slightly higher integrated COP of the two configurations, but almost negligible compared with the accuracy of the calculation. The reciprocating compressor produced heating capacity that was within 1% of the original scroll compressor. Given that both systems produced discharge pressures that were within 3% during defrost, the reciprocating compressor produced higher-energy discharge gas, which reduced the defrost time over that of the scroll-compressor-equipped system.
