技术领域technical field
本发明涉及一种利用太阳能作为能源动力，并具有跨季节蓄热蓄冷功能的冷热联供空调系统，该技术涵盖太阳能集热技术、吸收式制冷技术、蓄热蓄冷技术等技术领域。The invention relates to a combined cooling and heating air-conditioning system using solar energy as energy power and having the function of cross-season heat storage and cold storage. The technology covers the technical fields of solar heat collection technology, absorption refrigeration technology, heat storage and cold storage technology, and the like.
背景技术Background technique
太阳能空调就是利用太阳能作为吸收式制冷机的能源来源进行制冷或供热的成套设备。太阳能空调耗电极少，无污染无排放，运行安静无噪声，是很有发展前景的新能源利用设备。当前，太阳能空调主要由太阳能平板集热器、吸收式制冷机两大主要部分组成。太阳能平板集热器收集太阳能，产生80℃～100℃的热水，热水作为驱动热源进入吸收式制冷机，吸收式制冷机产生冷媒水进入空调末端。虽然太阳能有很多优点，比如能量是巨大的，普遍的，长久的和无害的。同时，太阳能作为可利用能源也有其明显的局限性，比如能量密度低，热辐射强度随机性大，而且具有间歇性。目前太阳能空调的主要问题就是制冷效率低、受太阳辐射波动影响大而工作不稳定，太阳能无法存储，热量不能根据实际需要调节，因此不能保证全年可靠、高效工作。A solar air conditioner is a complete set of equipment that uses solar energy as the energy source of an absorption refrigerator for cooling or heating. Solar air conditioners consume very little electricity, have no pollution, no emissions, and operate quietly and without noise. They are new energy utilization devices with great development prospects. At present, solar air conditioners are mainly composed of two main parts: solar plate collectors and absorption refrigerators. The solar flat plate collector collects solar energy and generates hot water at 80°C to 100°C. The hot water enters the absorption chiller as a driving heat source, and the absorption chiller produces refrigerant water that enters the air conditioner terminal. Although solar energy has many advantages, such as energy is huge, universal, long-lasting and harmless. At the same time, as an available energy source, solar energy also has its obvious limitations, such as low energy density, high randomness and intermittent nature of thermal radiation intensity. At present, the main problems of solar air conditioners are low cooling efficiency, unstable work due to the great influence of solar radiation fluctuations, solar energy cannot be stored, and heat cannot be adjusted according to actual needs, so reliable and efficient work cannot be guaranteed throughout the year.
针对太阳能空调的上述局限性，本发明运用太阳能高温集热技术显著提高集热效率，采用中高温复合蓄热材料设计合理高效的蓄热器－换热器结构，使得能量间歇不稳定输入与能量持续稳定输出两个工作状态相分离，实现太阳能空调的稳定运行。同时，建立可以实现跨季节蓄冷的蓄能装置，对太阳能进行跨季节的存储和输出，根据不同季节对空调的冷热需求量不同进行调配。Aiming at the above-mentioned limitations of solar air conditioners, this invention uses solar high-temperature heat collection technology to significantly improve heat collection efficiency, and uses medium-high temperature composite heat storage materials to design a reasonable and efficient heat accumulator-heat exchanger structure, so that intermittent unstable input of energy and continuous energy The two working states of the stable output are separated to realize the stable operation of the solar air conditioner. At the same time, build an energy storage device that can store cold across seasons, store and output solar energy across seasons, and deploy it according to the different demand for cold and heat of air conditioners in different seasons.

该系统还包括冷却塔，所述冷却塔两端分别通过第七三通换向阀和第八三通换向阀与建筑物的风机盘管并联。通过三通换向阀的控制，升温的冷却水可以向建筑物供暖，也可以流经冷却塔降温。The system also includes a cooling tower, the two ends of the cooling tower are respectively connected in parallel with the fan coil of the building through the seventh three-way reversing valve and the eighth three-way reversing valve. Through the control of the three-way reversing valve, the heated cooling water can heat the building or flow through the cooling tower to cool down.
集热系统：槽式集热器一般是以并联的形式连接在一起，通过光聚作用将照射到反光镜面上的太阳光聚焦到集热管中，集热管内流动导热油，导热油吸收热能达到高温（最高可达300℃）后进入高温储油罐。在高温储油罐中，导热油与吸收式制冷机发生器的热源水换热，提高热源水温度，驱动吸收式制冷机工作。导热油换热后温度降低，再次流入槽式集热器吸热，循环往复。Heat collection system: The trough heat collectors are generally connected together in parallel. The sunlight irradiated on the reflective mirror surface is focused into the heat collection tube through photocondensation. The heat transfer oil flows in the heat collection tube, and the heat transfer oil absorbs heat. After high temperature (up to 300°C), it enters the high temperature oil storage tank. In the high-temperature oil storage tank, the heat transfer oil exchanges heat with the heat source water of the generator of the absorption refrigerating machine, increases the temperature of the heat source water, and drives the absorption refrigerating machine to work. After heat exchange, the temperature of the heat transfer oil decreases, and it flows into the trough collector again to absorb heat, and the cycle goes on and on.
蓄热系统：相变蓄热器是一体化的相变蓄热/换热器，其内部设有两个换热器，一个是吸热换热器，一个是放热换热器。高温导热油通过吸热换热器将热量传递给相变蓄热材料，相变蓄热材料通过放热换热器将热量传递给制冷机的热源水或者建筑物的卫生热水，高温导热油不同时在相变蓄热器与高温储油罐中循环流动，由三通换向阀确定高温导热油流动路线。Heat storage system: The phase change heat storage is an integrated phase change heat storage/heat exchanger. There are two heat exchangers inside, one is a heat absorbing heat exchanger and the other is a heat releasing heat exchanger. The high-temperature heat transfer oil transfers heat to the phase-change heat storage material through the heat-absorbing heat exchanger, and the phase-change heat storage material transfers heat to the heat source water of the refrigerator or the sanitary hot water of the building through the heat release heat exchanger. It does not circulate in the phase change heat accumulator and the high-temperature oil storage tank at the same time, and the flow route of the high-temperature heat transfer oil is determined by the three-way reversing valve.
蓄冷系统：蓄冷水池是采用保温材料在地下建设的体积庞大的蓄冷系统。当需要蓄冷时，冷冻水从蒸发器出来后进入蓄冷水池蓄存。当需要调用蓄冷水时，蓄冷池出水口管道与空调末端的风机盘管连接，蓄冷水进入建筑物制冷。Cooling storage system: The cold storage pool is a bulky cold storage system constructed underground using thermal insulation materials. When cold storage is required, the chilled water comes out of the evaporator and enters the cold storage pool for storage. When the cold storage water needs to be used, the water outlet pipe of the cold storage pool is connected to the fan coil at the end of the air conditioner, and the cold storage water enters the building for cooling.
吸收式冷热联供系统：吸收式制冷机发生器的管内通有热源水，热源水在吸收式制冷机发生器和高温储油罐之间循环流动，流入吸收式制冷机发生器时放热，流入高温储油罐时吸热，循环往复。Absorption combined cooling and heating system: heat source water is passed through the pipe of the absorption refrigerator generator, and the heat source water circulates between the absorption refrigerator generator and the high-temperature oil storage tank, and releases heat when flowing into the absorption refrigerator generator , absorb heat when flowing into the high-temperature oil storage tank, and cycle back and forth.
本发明的系统运行原理：系统运行时，通过集热系统将太阳辐射能转变为导热工质（一般采用高温导热油）的热能，由换热器将导热油热能转化为热源水或被蓄存；通过蓄热系统来贮存集热器盈余的热量，在适当时候释放给制冷机或提供生活热水；通过蓄冷系统，可以保证在太阳能强度低或者无太阳辐射的时间实现连续供冷，也可以在不需供冷的季节将冷量储存起来；吸收式冷热联供系统利用高温热源水进行制冷，同时通过冷却水的排热作用提高冷却水温度，将排出的冷却水作供暖之用，从而实现冷热联供。The operating principle of the system of the present invention: when the system is running, the solar radiation energy is converted into the heat energy of the heat-conducting working medium (generally high-temperature heat-conducting oil) through the heat-collecting system, and the heat energy of the heat-conducting oil is converted into heat source water or stored by the heat exchanger ; Use the heat storage system to store the surplus heat of the collector, and release it to the refrigerator or provide domestic hot water at an appropriate time; through the cold storage system, it can ensure continuous cooling when the solar intensity is low or there is no solar radiation, and it can also Store the cooling capacity in the season when no cooling is needed; the absorption combined cooling and heating system uses high-temperature heat source water for cooling, and at the same time increases the temperature of the cooling water through the heat dissipation of the cooling water, and uses the discharged cooling water for heating. Thereby realizing combined cooling and heating.
本发明与现有技术相比，具有如下优点：本发明所设计的太阳能空调联供系统具有集热温度高、蓄放热速率快，全年工作稳定、制冷供热效率高的特点。本发明采用低成本的轻质有机材料开发槽式集热装置、高效紧凑式蓄热－换热交换器，获得稳定的中高温热源，驱动溴化锂吸收式制冷机制冷，提供稳定的冷、热负荷供给建筑物，并利用地下蓄冷水池对冷冻水进行蓄存。夏季建筑物需要制冷时，集热器吸收太阳能作为制冷机的驱动热源，并依靠相变蓄热器进行热量调节，稳定输出热源水的温度，保证制冷机稳定工作。当无太阳辐射时，利用地下蓄水池所蓄冷冻水进行供冷。春秋季建筑物不需要冷量供应时，吸收式制冷机仍然工作，制取冷冻水存入地下蓄冷水池，冬季制冷机工作时，不仅可以蓄存冷冻水，还可以将冷却水加热后送入空调末端的风机盘管，给建筑物供暖，实现全年太阳能的集约高效利用Compared with the prior art, the present invention has the following advantages: the solar air-conditioning cogeneration system designed by the present invention has the characteristics of high heat collection temperature, fast heat storage and release rate, stable work throughout the year, and high cooling and heating efficiency. The invention uses low-cost light organic materials to develop trough-type heat collectors and high-efficiency compact heat storage-heat exchange exchangers to obtain stable medium-high temperature heat sources, drive lithium bromide absorption refrigerators for refrigeration, and provide stable cooling and heating loads Supply buildings and store chilled water in underground cold storage tanks. When the building needs to be cooled in summer, the collector absorbs solar energy as the driving heat source of the refrigerator, and relies on the phase change heat accumulator to regulate the heat, stably output the temperature of the heat source water, and ensure the stable operation of the refrigerator. When there is no solar radiation, the frozen water stored in the underground reservoir is used for cooling. When the building does not need cold supply in spring and autumn, the absorption chiller still works to produce chilled water and store it in the underground cold storage pool. When the chiller works in winter, it can not only store chilled water, but also heat the cooling water and send it The fan coil unit at the end of the air conditioner provides heating to the building and realizes the intensive and efficient use of solar energy throughout the year
