Description
技术领域：Technical field:
本发明涉及一种带贮能的双热源供热太阳能热泵干燥设备，属新能源技术领域。The invention relates to a dual heat source heating solar heat pump drying equipment with energy storage, which belongs to the technical field of new energy.
背景技术：Background technique:
热泵干燥能有效地回收利用空气的能量，因此其运用越来越广泛。把热泵技术和太阳能热利用技术有机地结合起来，组成太阳能热泵干燥系统，以太阳能转换的热能作为热泵的热源，从而向干燥箱供热，它比空气源热泵干燥设备更节能。但是太阳能热泵在阴天、雨天以及晚上等太阳能不足时候，太阳能热泵提供的热量达不到干燥箱设定温度所需的能量，因此添加辅助加热系统以及贮热系统就十分必要。Heat pump drying can effectively recycle the energy of air, so its application is more and more widely. Organically combine heat pump technology and solar heat utilization technology to form a solar heat pump drying system, using the heat converted from solar energy as the heat source of the heat pump to supply heat to the drying box, which is more energy-efficient than air source heat pump drying equipment. However, when the solar heat pump is insufficient in cloudy days, rainy days, and nights, the heat provided by the solar heat pump cannot reach the energy required for the set temperature of the drying oven. Therefore, it is necessary to add an auxiliary heating system and a heat storage system.
发明内容：Invention content:

控制方案为：干燥箱1的温度传感器24通过温度比较将信息反馈至控制器25，控制器25控制电动风阀3、电动风阀9以及电辅助加热器15；白天太阳能充足的时候，冷媒通过水冷式蒸发器19、蒸发器11分别从热水、空气中获取热量再通过冷凝器给干燥箱1供热，当干燥箱1内的温度高于设定温度2℃时，电动风阀3的风门变大，排湿速度加快，排出的湿空气和外界空气一起通过空气集热器5被送至贮热箱6，叉排铝壳石蜡管束7的石蜡熔化,直至干燥箱1温度降为设定温度，电动风阀3的风门变小；白天太阳能不充足的时候，当干燥箱1内的温度达不到设定温度时，电辅助加热器15启动工作，电动风阀3的风门变小；晚上石蜡凝固释放能量，电动风阀9打开，冷媒通过蒸发器11从贮热箱6排出的热风中获得能量，进而给干燥箱1供热，当干燥箱1内的温度达不到设定温度时，电辅助加热器15启动工作。The control scheme is: the temperature sensor 24 of the drying box 1 feeds back the information to the controller 25 through temperature comparison, and the controller 25 controls the electric damper 3, the electric damper 9 and the electric auxiliary heater 15; The water-cooled evaporator 19 and evaporator 11 obtain heat from hot water and air respectively, and then supply heat to the drying box 1 through the condenser. When the temperature in the drying box 1 is 2°C higher than the set temperature, the electric air valve 3 The damper becomes larger, and the speed of dehumidification is accelerated, and the discharged humid air is sent to the heat storage tank 6 through the air heat collector 5 together with the outside air, and the paraffin in the aluminum shell paraffin tube bundle 7 of the fork row is melted until the temperature of the drying box 1 drops to the set temperature. When the temperature is fixed, the damper of the electric damper 3 becomes smaller; when the solar energy is insufficient during the day, when the temperature in the drying box 1 does not reach the set temperature, the electric auxiliary heater 15 starts to work, and the damper of the electric damper 3 becomes smaller At night, the paraffin wax solidifies and releases energy, and the electric air valve 9 is opened, and the refrigerant obtains energy from the hot air discharged from the heat storage tank 6 through the evaporator 11, and then supplies heat to the drying box 1. When the temperature in the drying box 1 does not reach the setting temperature, the electric auxiliary heater 15 starts to work.
如说明书附图图1所示：As shown in Figure 1 of the attached drawing of the manual:
本发明的有益效果是：巧妙的回收了干燥箱的排除的湿空气的能量，排出的湿空气与外界空气通过空气集热器再一起被加热，再通到贮热箱使石蜡熔化，晚上石蜡凝固又把热量释放出来，重新作为热泵的一个热源给干燥箱提供热量。The beneficial effect of the present invention is: the energy of the humid air discharged from the drying box is ingeniously reclaimed, the discharged humid air and the outside air are heated together through the air heat collector, and then passed to the heat storage tank to melt the paraffin wax, and the paraffin wax can be melted at night. The solidification releases the heat again, which is used as a heat source of the heat pump to provide heat to the drying box again.
