技术领域technical field

本发明属于可再生能源利用技术领域，具体涉及适用于高速公路服务区的清洁蓄能耦合太阳能供暖系统。The invention belongs to the technical field of renewable energy utilization, and in particular relates to a clean energy storage coupled solar heating system suitable for expressway service areas.

背景技术Background technique

高速公路服务区作为能源半孤岛，远离城市，远离集中供热管网、供电电网。传统的服务区多采用燃煤锅炉供暖，能源利用效率低，且污染严重。如今随着节能理念的不断深入，服务区设施大面积升级改造。远距离铺设天然气管道投资成本过大且有泄漏危险使煤改气无法实现。地缘热泵和空气源热泵虽然能够实现冷热连供，提高能源使用效率，但是初投资过大，投资回收期漫长。而相变储能技术在煤改电、清洁能源消纳、电网削峰填谷等方面作用突出，因此可以作为服务区设备升级改造的一个方向，与传统的热水锅炉采暖相比，无需锅炉、散热器等设备，能够减少初投资和地上空间的占用。As an energy semi-island, the expressway service area is far away from the city, central heating pipe network and power supply grid. Traditional service areas mostly use coal-fired boilers for heating, which has low energy utilization efficiency and serious pollution. Nowadays, with the continuous deepening of the concept of energy saving, the facilities in the service area have been upgraded and renovated on a large scale. The investment cost of long-distance laying of natural gas pipelines is too high and the risk of leakage makes it impossible to realize coal-to-gas conversion. Although geothermal heat pumps and air source heat pumps can achieve continuous cooling and heating and improve energy efficiency, the initial investment is too large and the investment payback period is long. The phase-change energy storage technology plays a prominent role in coal-to-electricity conversion, clean energy consumption, power grid peak-shaving and valley filling, etc., so it can be used as a direction for equipment upgrades in service areas. Compared with traditional hot water boiler heating, no boiler is required , radiators and other equipment can reduce the initial investment and the occupation of ground space.

Figure 6 shows the heat storage temperature change of the phase change energy storage module. The smooth section in the curve represents a constant temperature, indicating that the phase change material is storing heat, and the heat storage process is constant and lasts for a long time.

相变蓄能模块尺寸可根据项目实际情况配置，所需数量根据建筑热负荷计算得出。太阳能集热器可结合建筑外形特点，与建筑一体化。它的作用在于利用清洁廉价的太阳能降低电热转换所需的总电功率，并利用蓄能模块延长太阳能的使用时间(白日蓄热，夜间放热)。电加热盘管主要是指电加热装置，利用夜间谷值廉价电进行电热转化，所产生的热量被相变蓄热模块吸收蓄存，在白日内释放供热。这样就形成了白天太阳能+夜间廉价电的双蓄能模式。两者互补：夜间廉价电可弥补太阳能能量密度的不均匀性，而白日太阳能可减小夜间廉价电的用电总功率，进一步降低运营费用。太阳能、廉价电和相变蓄能模块之间的实时联动关系如下公式所示：The size of the phase change energy storage module can be configured according to the actual situation of the project, and the required quantity is calculated according to the building heat load. The solar thermal collector can be integrated with the building in combination with the shape of the building. Its function is to use clean and cheap solar energy to reduce the total electric power required for electrothermal conversion, and to use energy storage modules to extend the use time of solar energy (heat storage during the day and heat release at night). The electric heating coil mainly refers to the electric heating device, which utilizes the cheap electricity at the valley value at night to carry out electrothermal conversion, and the heat generated is absorbed and stored by the phase change heat storage module, and released for heat supply during the day. In this way, a dual energy storage mode of solar energy during the day and cheap electricity at night is formed. The two complement each other: cheap electricity at night can make up for the unevenness of solar energy density, and solar energy during the day can reduce the total power consumption of cheap electricity at night, further reducing operating costs. The real-time linkage relationship between solar energy, cheap electricity and phase change energy storage modules is shown in the following formula:

I为太阳能，F为集热面积，W为电加热装置功率，M为蓄热模块蓄热能力，C为循环介质比热容，m为介质质量，t代表时间，T代表温度。I is solar energy, F is the heat collecting area, W is the power of the electric heating device, M is the heat storage capacity of the heat storage module, C is the specific heat capacity of the circulating medium, m is the mass of the medium, t is time, and T is temperature.

本发明适用于高速公路服务区的清洁蓄能耦合太阳能供暖系统的工作过程是：The working process of the clean energy storage coupling solar heating system applicable to the expressway service area of the present invention is:

阶段一：白天8时至20时峰段电价阶段，太阳能独立供热，太阳能集热器出水温度大于30℃时循环水泵启动，开始向相变蓄能模块箱体左半部分通水，当换热使左侧箱体温度超过33℃时，定形相变蓄能板5-5内部十水硫酸钠熔化，开始蓄热；同时相变蓄能模块箱体右侧箱体温度低于33℃，定形相变蓄能板5-5中的十水硫酸钠开始凝固，向房间释放热量，当空气温度高于30℃，风机启动，维持房间温度在18℃～22℃范围内，满足白天供暖需要。Phase 1: During the peak electricity price period from 8:00 to 20:00 during the day, solar energy supplies heat independently, and the circulating water pump starts when the outlet water temperature of the solar collector is greater than 30°C, and starts to supply water to the left half of the phase change energy storage module box. When the heat makes the temperature of the left box exceed 33°C, the sodium sulfate decahydrate inside the fixed phase change energy storage plate 5-5 will melt and start to store heat; at the same time, the temperature of the right box of the phase change energy storage module box will be lower than 33°C, The sodium sulfate decahydrate in the shaped phase change energy storage plate 5-5 begins to solidify and release heat to the room. When the air temperature is higher than 30°C, the fan starts to maintain the room temperature within the range of 18°C to 22°C, meeting the heating needs during the day .

阶段二：夜间20时至次日8时谷段电价阶段，太阳能集热器停止工作，相变蓄能模块箱体右半部分电加热蓄能启动，使右侧箱体温度上升，定形相变蓄能板5-5中十水硫酸钠开始熔化，开始蓄热，电加热温度维持在40℃左右，保证相变蓄热的时间超过6h；同时相变蓄能模块箱体左半部分由于太阳能集热器停止供热，温度降低，定形相变蓄能板5-5中十水硫酸钠开始凝固，向房间释放热量，当空气温度高于30℃，风机启动，维持房间温度在18℃～22℃范围内，满足夜间供暖需要。Phase 2: From 20:00 at night to 8:00 the next day, the solar collector stops working, and the electric heating and energy storage of the right half of the phase change energy storage module box is started, so that the temperature of the right side box rises and the phase change is fixed. The sodium sulfate decahydrate in the energy storage plate 5-5 begins to melt and start to store heat. The electric heating temperature is maintained at about 40°C to ensure that the phase change heat storage time exceeds 6 hours; at the same time, the left half of the phase change energy storage module box is heated The collector stops heating, the temperature drops, and the sodium sulfate decahydrate in the fixed-shape phase change energy storage plate 5-5 begins to solidify, releasing heat to the room. When the air temperature is higher than 30°C, the fan starts to maintain the room temperature at 18°C~ Within the range of 22 ℃, it can meet the heating needs at night.

两个阶段，房间的室内温度均维持在人体可接受温度范围内，可以满足实际条件下冬季供暖的需要。工作人员通过外部控制器实时接收、监控温湿度记录仪的温度，避免相变蓄能模块内部的温度过高或过低，当太阳能进水温度或电加热温度超过60℃时，自动报警装置会提醒工作人员减少热水或电能输入；当太阳能进水温度或电加热温度低于30℃时，自动报警装置会提醒工作人员增加热水或电能输入。In the two stages, the indoor temperature of the room is maintained within the acceptable temperature range of the human body, which can meet the heating needs in winter under actual conditions. The staff receives and monitors the temperature of the temperature and humidity recorder in real time through the external controller to avoid the temperature inside the phase change energy storage module being too high or too low. When the solar water inlet temperature or the electric heating temperature exceeds 60°C, the automatic alarm device will Remind the staff to reduce hot water or electric energy input; when the solar water inlet temperature or electric heating temperature is lower than 30°C, the automatic alarm device will remind the staff to increase hot water or electric energy input.
