摘要: 节能减排与舒适健康是房间空调器发展的必然方向。根据全球制冷技术创新大奖赛确立的降低空调器气候影响80%的目标,研发出额定制冷量为5200 W的集成智能通风与光伏的超高效空调器。该高效空调器采用R152a制冷剂,由梯级冷却补气高效制冷循环系统、蒸发冷却新风系统、光伏直驱系统和自动控制系统四部分组成,按照印度新德里气象模拟得到的全年用电量为585 kW•h,与采用R22为制冷剂、能效比EER=3.5的基准样机相比节电80.2%。以此研发的空调器,根据印度IS 1391标准测得的额定制冷能效比EER=6.28,ISEER=8.43;在全年气候特征模拟实验室的10个典型气象日测试中,总节能量达到82.8%;在31天的实际现场应用测试结果表明,空调器能够稳定地控制室内温湿度(室温不高于27℃,相对湿度不高于60%)。计算得到的综合节电率为84.1%,折合气候影响降低85.7%。

Abstract: Energy saving, carbon emission reduction, thermal comfort and health are the inevitable way of the development of room air conditioner. Based on the goal of reducing the climate impact of air conditioner by 80% set by the Global Cooling Prize committee, a 5200 W ultra-efficient air conditioner with smart evaporative cooling ventilation and PV was developed. It is composed of high efficiency gas-injected vapor compression cycle with relay cooling, evaporative cooling fresh air system, photovoltaic system and automatic control system, which take R152a as the refrigerant. The simulated simulation annual power consumption is 585 kW•h in New Delhi, India, which is 80.2% less than the basic prototype with R22 as refrigerant and EER = 3.5. According to the test progress of IS 1391, the tested rating EER is 6.28 and ISEER reach 8.43. Moreover, in the 10-day lab test to simulate year-round performance, the total energy saving reached 82.8%. The results of 31 days field test show that the air conditioner can stably control the indoor temperature and humidity (room temperature ≤ 27 °C, relative humidity ≤ 60%). The calculated comprehensive electricity saving rate is 84.1%, equivalent to 85.7% reduction in climate impact.
