一种基于热泵技术的开闭双模结合型烘干系统
摘要：
本发明提供一种基于热泵技术的开闭双模结合型烘干系统，包括烘干热泵机组和烘箱，烘干热泵机组内设有加热升温腔、混合冷凝腔、混合蒸发腔、烘箱回风腔，烘干热泵机组还包括位于混合蒸发腔内的蒸发器和蒸发侧调速循环风机、位于所述混合冷凝腔内的冷凝器和冷凝侧调速循环风机、位于所述加热升温腔内的电辅助加热器，蒸发侧调速循环风机与蒸发器相对，冷凝侧调速循环风机与冷凝器的进风口相对，电辅助加热器与与冷凝器的出风口相对，蒸发器两侧和冷凝器两侧均分别设有与烘干热泵机组相连接的挡板。本发明与现有技术相比，实现开式烘干除湿模式和闭式烘干除湿模式的双模式切换，克服单一模式的缺陷，实现了高效烘干除湿效果。
摘要（英）：

The invention provides an open-close dual-mode combined drying system based on a heat pump technology. The system comprises a drying heat pump unit and an oven, a heating cavity, a mixed condensing cavity, a mixed evaporating cavity and an oven air return cavity are arranged in the drying heat pump unit. The drying heat pump unit further comprises an evaporator, an evaporating side speed regulation circulating fan, a condenser, a condensing side speed regulation circulating fan and an electric auxiliary heater, wherein the evaporator and the evaporating side speed regulation circulating fan are located in the mixed evaporating cavity, the condenser and the condensing side speed regulation circulating fan are located in the mixed condensing cavity, the electric auxiliary heater is located in the heating cavity, the evaporating side speed regulation circulating fan is opposite to the evaporator, the condensing side speed regulation circulating fan is opposite to an air inlet of the condenser, the electric auxiliary heater is opposite to an air outlet of the condenser, and baffles connected with the drying heat pump unit are arranged on the two sides of the evaporator and the two sides of the condenser correspondingly. Compared with the prior art, the open drying dehumidification mode and the closed drying dehumidification mode are switched, the defect of a single mode is overcome, and the high-efficiency drying dehumidification effect is realized.
