一种盘管辅热双胆式太阳能空气能热水器水箱A kind of coil auxiliary heating double tank type solar air energy water heater water tank

技术领域 technical field

本发明涉及太阳能与空气能综合利用技术,具体是指一种节能、环保、高效、稳定运行的户式盘管辅热双胆式太阳能空气能热水器水箱,属于太阳能、空气能热水器的技术领域。 The invention relates to the comprehensive utilization technology of solar energy and air energy, specifically refers to an energy-saving, environment-friendly, high-efficiency, and stable household-type coil auxiliary heating double-tank solar air energy water heater water tank, which belongs to the technical field of solar energy and air energy water heaters.

背景技术 Background technique

我国家用热水器的常用热源主要有太阳能、空气能、电能、燃气等。太阳能热水器利用可再生的太阳能资源,且运行基本不需要消耗其他能源;空气能热水器则是以电能为动力的空气能利用系统,与电热水器相比,其热效率是电热水器的300%-500%;我国电力生产目前仍以火电为主,电热水器和燃气热水器运行主要靠消耗不可再生能源来获得热水。 Commonly used heat sources for domestic water heaters in my country mainly include solar energy, air energy, electric energy, and gas. Solar water heaters use renewable solar energy resources, and basically do not need to consume other energy for operation; air energy water heaters are air energy utilization systems powered by electric energy. Compared with electric water heaters, their thermal efficiency is 300%-500% of electric water heaters my country's electric power production is still dominated by thermal power at present, and the operation of electric water heaters and gas water heaters mainly depends on the consumption of non-renewable energy to obtain hot water.

我国是一个太阳能资源丰富的国家,近年来太阳能热水器在我国的研究和应用得到了迅速发展,但太阳能资源受季节变化和天气变化的影响很大,在冬季生产热水能力较差,尤其在阴雨天甚至不能生产热水,因此,太阳能热水器往往需要设置辅助热源。目前太阳能热水器常用的辅助能源是电能,实际运行中如果辅助电能控制不当,电能消耗量将大于太阳能获得量,甚至出现在相同的热水使用量下太阳能热水器的辅助耗电量大于单纯电热水器耗电量,太阳能热水器起不到利用太阳能的节能效果,因此,太阳能热水器辅助热源形式选择、热水系统节能设计是太阳能光热技术发展面临的一个重要问题。 my country is a country rich in solar energy resources. In recent years, the research and application of solar water heaters in our country has developed rapidly. However, solar energy resources are greatly affected by seasonal changes and weather changes. The ability to produce hot water in winter is poor, especially in rainy weather. The sky cannot even produce hot water, therefore, solar water heaters often need to set an auxiliary heat source. At present, the commonly used auxiliary energy for solar water heaters is electric energy. If the auxiliary electric energy is not properly controlled in actual operation, the electric energy consumption will be greater than the solar energy gain, and even under the same hot water consumption, the auxiliary power consumption of solar water heaters is greater than that of pure electric water heaters. Therefore, the selection of auxiliary heat sources for solar water heaters and the energy-saving design of hot water systems are important issues facing the development of solar thermal technology.

空气能热水器是近年来发展较快的另一种高效、节能的生活热水制备技术,与太阳能热水技术相比,空气能热水器在我国南方地区运行基本不受季节和天气的影响,因此,太阳能与空气能综合利用技术是我国南方地区十分理想的生活热水生产技术之一。我国南方地区住宅中,分体空调是十分普及的家用电器,在一年中家用空调的使用率一般很低。因此,充分利用热泵技术原理,在室内舒适空调运行同时兼顾为太阳能热水器提供辅助热源,不但可以实现太阳能和空气能这二种可再生能源的综合利用,还可以提高家用空调系统的使用效率。其中,设计一种稳定运行、体积小、制造简单、制造成本低、保温节能效率高的热水器水箱是这种太阳能与空气能综合利用技术所面临解决的重要问题之一。 Air energy water heaters are another high-efficiency and energy-saving domestic hot water preparation technology that has developed rapidly in recent years. Compared with solar water heating technology, air energy water heaters are basically not affected by seasons and weather in southern my country. Therefore, The comprehensive utilization technology of solar energy and air energy is one of the ideal domestic hot water production technologies in southern my country. Split air conditioners are very popular household appliances in residential houses in southern my country, and the utilization rate of household air conditioners is generally very low in a year. Therefore, making full use of the principle of heat pump technology and providing auxiliary heat sources for solar water heaters while operating comfortably in indoor air conditioners can not only realize the comprehensive utilization of solar energy and air energy, but also improve the efficiency of household air conditioning systems. Among them, designing a water heater tank with stable operation, small size, simple manufacture, low manufacturing cost, high thermal insulation and energy saving efficiency is one of the important problems faced by this comprehensive utilization technology of solar energy and air energy.

When the solar radiation is sufficient, the solar domestic hot water system is turned on. When the solar radiation is not sufficient or the weather is rainy, the solar and air combined hot water system is turned on. The operation of each working mode is as follows.

太阳能独立制生活热水工况的具体操作为:空气能热泵断电,电动三通换向阀14和控制器17通电;系统在太阳能独立制生活热水工况的运行机理为:最初控制为电动三通换向阀14处于旁通管18连通、水箱进水管断开;太阳能循环水在太阳能集热器内吸收热量后,循环进入太阳能循环水进水管6,温度传感器一15实时监测太阳能循环水进水管6内水温,温度传感器二16实时监测承压水箱内胆10下部水温,当温度传感器一15的监测温度低于温度传感器二16的监测温度时,太阳能循环水为低温循环流动,不但不能加热承压水箱内胆10内的热水,甚至将带走承压水箱内胆10内热水的热量,此时控制器17控制电动三通换向阀14,使太阳能循环水进水管6断开,旁通管18连通,太阳能循环水不进入水箱外胆11而经旁通管18循环流动;当温度传感器一15的监测温度高于温度传感器二16的监测温度时,太阳能循环水进水管6的水可以用于加热承压水箱内胆10内的热水,此时控制器17控制电动三通换向阀14,使太阳能循环水进水管6连通,旁通管18断开,太阳能循环水不进入旁通管18而经水箱外胆11循环流动并供热。 The specific operation of the solar energy independent domestic hot water production condition is: the air source heat pump is powered off, the electric three-way reversing valve 14 and the controller 17 are powered on; the operating mechanism of the system in the solar independent domestic hot water production condition is: the initial control is The electric three-way reversing valve 14 is connected to the bypass pipe 18, and the water inlet pipe of the water tank is disconnected; after the solar circulating water absorbs heat in the solar collector, it circulates into the solar circulating water inlet pipe 6, and the temperature sensor 15 monitors the solar cycle in real time The water temperature in the water inlet pipe 6, the temperature sensor two 16 real-time monitoring of the water temperature of the lower part of the pressurized water tank liner 10, when the monitoring temperature of the temperature sensor one 15 is lower than the monitoring temperature of the temperature sensor two 16, the solar circulating water is a low-temperature circulation flow, not only The hot water in the pressurized water tank liner 10 cannot be heated, and even the heat of the hot water in the pressurized water tank liner 10 will be taken away.
