摘要：作者：鄧爭鳴; 金寧; 鄭嘉耀 關(guān)鍵詞：性能,對比,空氣,熱水器,R22 【中文摘要】 在低溫環(huán)境下,研究了R22與R417A對空氣源熱泵熱水器的性能影響。得出了機組性能系數(shù)(COP)、制熱量、排氣壓力、壓縮機功率和水箱水溫與加熱時間的關(guān)系。 【英文摘要】 Under the low temperature environment, R22 and R417A influenced air source heat pump water heater were studied. And come to the relationship between the unit coefficient of performance(COP), heating capacity, exhaust pressure, tank water temperature, compressor power and heating time. 【中文關(guān)鍵詞】 空氣源熱泵熱水器; R22; R417A; 性能對比【英文關(guān)鍵詞】 air source heat pump water heater; R22; R417A; Performance comparison
