一种轻烃燃气驱动的空气源热泵A light hydrocarbon gas-driven air source heat pump

技术领域technical field

本发明涉及一种空气源热泵，具体涉及一种轻烃燃气驱动的空气源热泵，属于空气源热泵技术领域。The invention relates to an air source heat pump, in particular to an air source heat pump driven by light hydrocarbon gas, belonging to the technical field of air source heat pumps.

背景技术Background technique

目前在一般民用建筑物，空调的能耗占了58%以上，给电力供应带来很大的压力；我国已经把太阳能利用作为后续能源战略中可再生能源的重要组成部分，并出台了一系列的政策指导性文件鼓励和支持太阳能转化研究和应用事业的发展；传统的空气源热泵装置，采用压缩机作为机组的驱动部件，磨损程度大，噪音大，使用寿命短；例如：中国专利：CN102012129A中的一种节能型太阳能空气源热泵多功能机，使用压缩机作为驱动部件；传统的吸收式热泵装置大多数采用天然气、工业余热作为机组的驱动力，需要驱动能源购买成本，增加运行费用；例如：中国专利CN201561564U所公开的技术内容中，就是一燃气作为机组运行动力的；传统吸收热泵采用天然气作为驱动力，产生的烟气中带走了大量的热量，能源的利用率低，并且传统热泵机组所用的制冷剂工质的性质决定了其不能在低温下稳定运行；为此，我们研发了一种太阳能空气源吸收式热泵装置（中国专利申请号：201210361473.5），如图1所示，其具体如下：以天然能源太阳能作为机组的驱动能源，通过发生器中加热换热器将太阳能输入到太阳能热泵装置中，提供机组运行的动力。通过空气源热交换盘管吸收空气中的能量，这两部分的能量通过制冷剂蒸汽的冷凝和制冷剂蒸汽与稀溶液的熔解热释放出来，传递给热水，提高能源利用率；融霜时，利用进入空气源热交换盘管的制冷剂蒸汽除霜后与稀溶液溶解后放出的溶解热，保证了在除霜时仍然能够稳定地提供热量的方案；但太阳能供热会受到地区限制，从而无法很好地在各个区域进行推广应用。At present, in general civil buildings, the energy consumption of air conditioners accounts for more than 58%, which brings great pressure to the power supply; China has taken the utilization of solar energy as an important part of renewable energy in the follow-up energy strategy, and has issued a series of The policy guidance document of China encourages and supports the development of solar energy conversion research and application; the traditional air source heat pump device uses the compressor as the driving component of the unit, which has a large degree of wear, high noise and short service life; for example: Chinese patent: CN102012129A One of the energy-saving solar air-source heat pump multi-function machines in the system uses a compressor as a driving component; most of the traditional absorption heat pump devices use natural gas and industrial waste heat as the driving force of the unit, which needs to drive the purchase cost of energy and increase the operating cost; For example, in the technical content disclosed in Chinese patent CN201561564U, a gas is used as the operating power of the unit; the traditional absorption heat pump uses natural gas as the driving force, and the generated flue gas takes away a lot of heat, the utilization rate of energy is low, and the traditional absorption heat pump uses natural gas as the driving force. The nature of the refrigerant used in the heat pump unit determines that it cannot operate stably at low temperatures; for this reason, we have developed a solar air source absorption heat pump device (China Patent Application No.: 201210361473.5), as shown in Figure 1, The details are as follows: natural energy solar energy is used as the driving energy of the unit, and the solar energy is input into the solar heat pump device through the heating heat exchanger in the generator to provide the power for the operation of the unit. The energy in the air is absorbed by the air source heat exchange coil, and the two parts of energy are released by the condensation of the refrigerant vapor and the heat of fusion between the refrigerant vapor and the dilute solution, and transferred to the hot water to improve the energy utilization rate; when defrosting , using the heat of solution released by the refrigerant vapor entering the air source heat exchange coil after defrosting and dissolving with the dilute solution to ensure that the heat can still be stably provided during defrosting; however, solar heating will be limited by regions. Therefore, it cannot be well promoted and applied in various regions.

The heated air can not only vaporize light hydrocarbons Provides an initial latent heat; at the same time, it can vaporize the ammonia liquid inside the gasification chamber, and the heated and refined air is injected into the check valve inside the gasifier, and the refined hot gas is passed through the check valve and the gasification head. Evenly spray the light hydrocarbon oil to generate light hydrocarbon gas. During gasification, the light hydrocarbon oil in the high-level storage tank is driven into the inside of the gasifier through the liquid level ball valve, so that light hydrocarbons with shallow liquid surface are formed inside the gasifier. Oil, the gasified light hydrocarbon gas is sent to the ignition nozzle for ignition. Because the refined hot gas is mixed with the light hydrocarbon oil, the combustion efficiency of the light hydrocarbon gas is greatly improved, and the utilization rate of the light hydrocarbon gas is high; When the gas is gasified to a certain capacity, the heating wire is turned off, and the ignition is carried out through the ignition nozzle. The high temperature heat generated by the light hydrocarbon gas is absorbed by the phase change layer inside the heating interlayer, and the gasification chamber is directly heated at the same time. The ammonia water inside is gasified, and at the same time, the refined gas in the heat exchange coil inside the gasification tank is heated, and is driven into the gasifier to continue to provide latent heat for light hydrocarbon oil, which recovers part of the heat in the ammonia gas, and when the ignition nozzle burns After a certain time, the controller controls the ignition nozzle to extinguish the fire, the inner tube in the phase change layer continues to gasify, and the ammonia gas continues to heat the heat exchange coil, which can recover part of the heat in the ammonia gas and continue to transfer it to the gasification. In the furnace, when the gasifier is ignited for the second time, there is no need for the electric heating wire to perform secondary heating to provide latent heat; at the same time, ammonia gas can continue to provide evaporation heat source for the generator of the air source absorption heat pump system; when the online temperature detector detects the temperature When the temperature drops to the first-level threshold, auxiliary heating can be performed through the heating wire. When the online temperature detector detects that the temperature drops to the second-level threshold, the heating wire is turned off. At this time, the ignition nozzle is turned on to continue to provide gasification for the gasification chamber. Heat and phase change layers store heat.
