变频回热式热泵烤烟房的研究

由于传统烤烟容易出现青烟、挂灰、黑糟、阴筋和烤红等影响烤烟质量的问题,目前我国烤烟房主要以立式炉或蜂窝煤火炉作热源,地窖和天窗作排气除湿口,这种方法能源消耗大,效率低。为了解决这些问题,采用变频回热式热泵系统作热源供给烤烟房热量,通过改变压缩机的转速,使压缩机的热负荷的变化与热泵烤房内的热量变化达到最佳匹配,同时再利用回热器使烤烟房排出湿空气的热量来加热蒸发器的干空气以提高热泵干燥系统的去湿能力。变频回热热泵在满足相同的热负荷的情况下,所需要付出的功减小,所以变频回热泵具有省电和性能系数高等优点,具有广阔的发展前景。

Research on Frequency Conversion Regenerative Heat Pump Cured Tobacco Room

Because of the problems of traditional cured tobacco that green tobacco,ash,black bad,cloudy muscle,roasted red affecting the quality of cured tobacco,the present heat sources of cured tobacco room mainly were vertical stove or honeycomb coal stove,exhaust and dehumidification were the cellar and skylight,this method was large energy consumption and low efficiency.In order to solve the above problems,heat source was frequency conversion regenerative heat pump.By changing the speed of the compressor,the compressor heat flux and heat change of heat pump room achieved the best match.Meanwhile forced the heat recovery,the air coming from drying room was cooled before entering the evaporator and the air from the evaporator was heated by heat recovery exchanger,the drying ability of the heat pump drying system was increased.Frequency conversion heat pump to meet the same thermal load cases,the power required could be reduced.Therefore,the frequency conversion heat pump had the advantages of energy saving,high coefficient of performance and had broad prospects for development.
