The moisture extraction rate (MER) and energy efficiency of domestic gas clothes dryers, heat-pump clothes dryers and electric clothes dryers were assessed. The assessment was performed with regard to five indices: the MER, specific MER, specific thermal energy consumption for dehumidification (m_SPC), energy efficiency (η_t) and primary energy efficiency (η₁). The effects of the dry mass of clothes (m_BD) and the ambient temperature on the performance of the clothes dryers were evaluated. The experiments were divided into two parts. In the first part, the ambient temperature was 20°C, and m_BD was set as 1.5, 2.5, 3.5, 4.5 and 6 kg. In the second part, m_BD was 3.5 kg, and the performance of the dryers was tested at ambient temperatures of 5, 7.5, 10, 12.5, 15 and 20°C. The experimental results indicated that the gas dryer had the highest MER the heat-pump dryer had the best performance with regard to energy conservation and all three types of dryers had a higher MER and energy efficiency when the ambient temperature increased. The performance of the gas dryer was lower than that of heat-pump dryer when the temperature was 20°C. But when the temperature was < 9.5°C, the primary energy efficiency of the gas dryer was higher than that of the heat-pump dryer.

燃气干衣机与其他两种家用干衣机性能的比较研究

评估了家用燃气干衣机，热泵干衣机和电动干衣机的水分提取率（MER）和能源效率。的MER，具体MER，特定的热能耗除湿（：该评估关于五个指标进行米_SPC），能量效率（η_吨）和初始能量效率（η ₁）。评估了干衣质量（m _BD）和环境温度对干衣机性能的影响。实验分为两部分。在第一部分中，环境温度为20°C，m _BD设定为1.5、2.5、3.5、4.5和6公斤。在第二部分中，m _BD为3.5 kg，并在5、7.5、10、12.5、15和20°C的环境温度下测试了干燥机的性能。实验结果表明，气体干燥器的MER最高，热泵干燥器的节能性能最佳，当环境温度升高时，这三种类型的干燥器均具有较高的MER和能效。当温度为20℃时，气体干燥器的性能低于热泵干燥器的性能。但是，当温度<9.5°C时，气体干燥器的一次能源效率要高于热泵干燥器的一次能源效率。
