摘要: 通过设定3 P环境模拟室房间温度波动2℃内为目标达到“无感化霜”效果,选定相变温度46℃石蜡为蓄热材料,理论计算设计了符合3 P空调室外机空间的蓄热器,并通过实验验证分析了蓄热化霜系统房间温度波动、出风温度、24 h持续制热运行衰减情况,并与传统逆向除霜系统对比了室外2℃时化霜温度波动,实验表明,2℃时蓄热化霜系统温度波动低至1℃,明显低于传统逆向化霜系统的5.67℃,且蓄热化霜系统化霜时最低出风温度在39.1℃以上,可以满足24 h长时间运行且波动低于1℃。

Abstract: By setting the temperature fluctuation of 3 P environment simulation room within 2℃ as the goal to achieve the effect of "no effect frost", the paraffin with phase change temperature of 46℃ is selected as the heat storage material, and the heat accumulator in line with the outer space of 3 P air conditioner is designed by theoretical calculation. Through experimental verification, the room temperature fluctuation, air outlet temperature and 24 h continuous heating operation attenuation of the heat storage defrosting system are analyzed. Compared with the traditional reverse defrosting system, the outdoor defrosting temperature fluctuation at 2℃ is compared. The experiment shows that the temperature fluctuation of the thermal storage defrosting system at 2℃ is as low as 1℃, significantly lower than 5.67℃ of the traditional reverse defrosting system, and the minimum air outlet temperature of the thermal storage defrosting system is above 39.1℃, which can meet the 24 h long-time operation and the fluctuation is less than 1℃.

Key words: Variable frequency air conditioner, Temperature fluctuation, Heat storage and defrosting, Continuous operation, Air outlet temperature
