Description

一种太阳能相变地板直供采暖系统及其控制方法 A solar phase change floor heating system and its control method

技术领域technical field

本发明属于太阳能利用和采暖技术领域，特别涉及一种相变地板蓄热采暖装置。The invention belongs to the technical field of solar energy utilization and heating, in particular to a phase-change floor heat storage heating device.

背景技术Background technique

目前我国太阳能热水器生产量和保有量均居世界第一，其中太阳能真空管技术已达到世界先进水平，成本相对较低。低温地板辐射采暖系统将整个地面作为辐射散热面，通过与其他围护结构表面进行辐射换热，提高围护结构内表面温度，室内设计温度可比散热器采暖形式低2～3℃，节能20％～30％。地板采暖水温在40～50℃即可以达到人体所需要的舒适度，因此地板采暖只需较低品位的热源，非常适合采用太阳能集热器提供的热水作为热源。然而与较为连续的地板辐射采暖需求相比，太阳能资源利用存在能量密度低，时间上分布不均的缺点，需要蓄热体将其存储后在夜间利用。At present, my country's solar water heater production and inventory rank first in the world, and the solar vacuum tube technology has reached the world's advanced level, and the cost is relatively low. The low-temperature floor radiant heating system uses the entire ground as a radiation heat dissipation surface, and through radiative heat exchange with other surfaces of the enclosure structure, the temperature of the inner surface of the enclosure structure is increased. The indoor design temperature can be 2-3°C lower than that of radiator heating, saving energy by 20%. ~30%. The water temperature of floor heating can reach the comfort level required by the human body at 40-50°C. Therefore, floor heating only needs a low-grade heat source, which is very suitable for using hot water provided by solar collectors as a heat source. However, compared with the relatively continuous demand for floor radiant heating, the utilization of solar energy resources has the disadvantages of low energy density and uneven time distribution, which requires a heat storage body to store it and use it at night.

中国发明专利(专利号：200610002606.4)“全自动太阳能地板采暖系统”使用真空管太阳能集热器、热水储罐、辅助热源、地板采暖系统，及温度控制回路组成。该系统利用太阳能与地板采暖相结合，节省了能耗，但其热水储罐体积大，造价高，且十分笨重，不适合在高层、轻质结构的建筑中使用，且结构较复杂，其传感，控制及动力部件较多，可靠性有待改进。Chinese invention patent (patent number: 200610002606.4) "Full-automatic solar floor heating system" is composed of vacuum tube solar collector, hot water storage tank, auxiliary heat source, floor heating system, and temperature control circuit. This system uses solar energy combined with floor heating to save energy consumption, but its hot water storage tank is bulky, expensive, and very heavy. It is not suitable for use in high-rise and light-weight buildings, and its structure is complicated. There are many sensing, control and power components, and the reliability needs to be improved.

图1为太阳能相变地板直供采暖系统图。该系统含有太阳能集热器1，地板采暖装置，辅助热源6以及温度时间控制装置，所述的地板采暖装置采用相变地板采暖装置10，太阳能集热器1通过集热器出水管3与辅助热源6连接，辅助热源6通过地板进水管7与相变地板采暖装置10连接；相变地板采暖装置10通过供热泵13、第一电磁阀16和集热器入水管19与太阳能集热器1连接，构成一个太阳能集热采暖回路；所述的相变地板采暖装置10通过供热泵13、第二电磁阀17、旁通管5与辅助热源6相连，构成辅助热源采暖回路；所述的温度时间控制装置，包括控制柜18，设置在太阳能集热器出口处的第一温度传感器2，设置在相变地板采暖装置中的第三温度传感器11，分别设置在相变地板采暖装置进出口处的第二温度传感器8和第四温度传感器12；所述的第一温度传感器2、第二温度传感器8、第三温度传感器11和第四温度传感器12分别通过信号线与控制柜18连接。Figure 1 is a diagram of a solar phase change floor direct heating system. The system contains a solar heat collector 1, a floor heating device, an auxiliary heat source 6 and a temperature time control device. The heat source 6 is connected, and the auxiliary heat source 6 is connected to the phase-change floor heating device 10 through the floor water inlet pipe 7; connected to form a solar collector heating circuit; the phase change floor heating device 10 is connected to the auxiliary heat source 6 through the heat pump 13, the second solenoid valve 17, and the bypass pipe 5 to form an auxiliary heat source heating circuit; the temperature The time control device includes a control cabinet 18, a first temperature sensor 2 arranged at the outlet of the solar collector, and a third temperature sensor 11 arranged in the phase-change floor heating device, respectively arranged at the entrance and exit of the phase-change floor heating device The second temperature sensor 8 and the fourth temperature sensor 12; the first temperature sensor 2, the second temperature sensor 8, the third temperature sensor 11 and the fourth temperature sensor 12 are respectively connected to the control cabinet 18 through signal lines.

晴天时，白天阳光充足，供热泵13和第一电磁阀16打开，第二电磁阀17关闭，将太阳能集热器1收集到的太阳能，通过水循环输送到相变地板采暖装置10中，给相变材料提供热量，相变材料一边满足房间白天的供暖需求，一边将剩余的热量存储起来，为了保证最低蓄热速度，当相变地板采暖装置进口处的第二温度传感器8所测温度低于45℃时，启动辅助热源6，提高供热水循环温度。当相变地板采暖装置进口处的第二温度传感器8所测温度高于45℃时，关闭辅助热源6。当相变地板蓄热结束，相变地板采暖装置中的第三温度传感器11所测温度高于40℃时，供热泵13停止供热。到了夜间，经过白天的蓄热，相变地板采暖装置10中的相变材料蓄热完毕，供热泵13停止运行，停止向相变地板采暖装置10提供热量。此时，相变地板采暖装置10依靠白天所蓄存下的热量为房间供暖。When it is sunny, the sun is sufficient during the day, the heat pump 13 and the first solenoid valve 16 are turned on, and the second solenoid valve 17 is turned off, so that the solar energy collected by the solar collector 1 is sent to the phase change floor heating device 10 through water circulation, and the phase change The heat is provided by the phase change material. While meeting the heating demand of the room during the day, the phase change material stores the remaining heat. In order to ensure the lowest heat storage speed, when the temperature measured by the second temperature sensor 8 at the entrance of the phase change floor heating device is lower than At 45°C, the auxiliary heat source 6 is activated to increase the circulating temperature of the hot water supply. When the temperature measured by the second temperature sensor 8 at the entrance of the phase-change floor heating device is higher than 45° C., the auxiliary heat source 6 is turned off. When the heat storage of the phase-change floor finishes and the temperature measured by the third temperature sensor 11 in the phase-change floor heating device is higher than 40° C., the heat supply pump 13 stops heating. At night, after heat storage during the day, the heat storage of the phase change material in the phase change floor heating device 10 is completed, and the heat supply pump 13 stops running to stop providing heat to the phase change floor heating device 10 . At this time, the phase-change floor heating device 10 relies on the heat stored during the day to heat the room.

阴天时，由于阳光不足，白天需要供热时，启动供热泵13和辅助热源6，打开第二电磁阀17，关闭第一电磁阀16，进行对相变地板采暖装置10供热，相变地板采暖装置10一边满足房间白天的供暖需求，一边将剩余的热量存储起来。到了夜间，经过白天的蓄热，相变地板采暖装置10蓄热完毕，供热泵13停止运行，停止向相变地板采暖装置10提供热量。此时，相变地板采暖装置10依靠白天所蓄存下的热量为房间供暖。On cloudy days, due to insufficient sunlight, when heating is required during the day, start the heat supply pump 13 and the auxiliary heat source 6, open the second solenoid valve 17, and close the first solenoid valve 16 to supply heat to the phase change floor heating device 10. The heating device 10 satisfies the heating demand of the room during the day and stores the remaining heat. At night, after heat storage during the day, the heat storage of the phase-change floor heating device 10 is completed, and the heat supply pump 13 stops running to stop providing heat to the phase-change floor heating device 10 . At this time, the phase-change floor heating device 10 relies on the heat stored during the day to heat the room.

夜间为了防止太阳能集热器1中存水结冰，当太阳能集热器出口处的第一温度传感器2所测温度低于5℃时，打开第一电磁阀16，关闭第二电磁阀17，启动供热泵13，将少量热水提供给太阳能集热器1，当太阳能集热器出口处的第一温度传感器2所测温度高于5℃时，停止供热泵13。In order to prevent the water stored in the solar collector 1 from freezing at night, when the temperature measured by the first temperature sensor 2 at the outlet of the solar collector is lower than 5°C, the first solenoid valve 16 is opened and the second solenoid valve 17 is closed. Start the heat pump 13 to provide a small amount of hot water to the solar collector 1, and stop the heat pump 13 when the temperature measured by the first temperature sensor 2 at the outlet of the solar collector is higher than 5°C.

夜间如果相变地板采暖装置热量不足供热无法满足房间需求时，此时系统表现为相变地板采暖装置中的第三温度传感器11所测温度小于22℃，可启动辅助热源采暖回路，为相变地板采暖装置补充热量。At night, if the heat of the phase-change floor heating device is insufficient to meet the needs of the room, the system will show that the temperature measured by the third temperature sensor 11 in the phase-change floor heating device is less than 22°C, and the auxiliary heat source heating circuit can be started, which is the phase-change floor heating device. Variable floor heating supplements the heat.

连续阴天或长期不用时，可打开泄水阀一4和泄水阀二14，将太阳能集热器1中的水排掉防冻，此时，不能启用太阳能集热器1采暖。待晴天后，可开启补水阀15进行补水。Continuous cloudy day or when not being used for a long time, can open drain valve one 4 and drain valve two 14, the water in the solar heat collector 1 is drained antifreeze, at this moment, can not enable solar heat collector 1 heating. After it is sunny, the water replenishment valve 15 can be opened to replenish water.

当水路系统中有存气，可开启排气阀20，将系统中的存气排出。When there is gas in the waterway system, the exhaust valve 20 can be opened to discharge the gas in the system.
