Description
技术领域Technical field
本发明属于家用供暖领域，具体是一种双热源热泵-太阳能联合供暖系统及方法。The invention belongs to the field of household heating, specifically a dual heat source heat pump-solar combined heating system and method.
背景技术Background technique
近些年来北方城市的供暖得到了越来越好的发展，然而北方的农村地区供暖问题一直停滞不前，还是采用较为传统普通煤炉进行采暖，卫生条件较差，生活质量得不到提升。因此，寻求一种适用于农村且节能、环保供暖方式是农村供暖问题的关键所在。In recent years, heating in northern cities has been developing better and better. However, the heating problem in rural areas in the north has been stagnant. Traditional coal stoves are still used for heating. The sanitary conditions are poor and the quality of life has not been improved. Therefore, finding an energy-saving and environmentally friendly heating method suitable for rural areas is the key to rural heating issues.
冬季采暖化石能源燃烧是导致雾霾的主要原因之一，因此改变北方农村传统的采暖方式，“煤改电”是改善空气质量的必经之路。然而如果直接用电进行取暖，直接将高品位电力转化为低品位热量则会浪费资源。因此考虑到农宅中部分采用土煤炉进行取暖，因此发展热泵供暖应该是解决北方农村供暖问题的最好方式。在北方，单一热源的热泵系统由于深冬温度较低会出现结霜、运行效率下降等一系列问题，因此，有必要对单一热源的热泵系统进行技术改进。The burning of fossil energy for heating in winter is one of the main causes of smog. Therefore, changing the traditional heating method in northern rural areas and "coal-to-electricity" is the only way to improve air quality. However, if electricity is used directly for heating, it will be a waste of resources to directly convert high-grade electricity into low-grade heat. Therefore, considering that some farm houses use earth-coal stoves for heating, the development of heat pump heating should be the best way to solve the heating problem in northern rural areas. In the north, heat pump systems with a single heat source will suffer from a series of problems such as frost formation and reduced operating efficiency due to low temperatures in late winter. Therefore, it is necessary to make technical improvements to the heat pump systems with a single heat source.

本发明的工作流程：Work flow of the present invention:
本发明有五个工作状态：晴天制热水状态、阴天供热水状态、初冬供暖状态、中冬供暖状态、深冬供暖状态。The invention has five working states: hot water heating state on sunny days, hot water supplying state on cloudy days, early winter heating state, mid-winter heating state, and late winter heating state.
晴天时太阳光照充足，太阳能集热器6将从太阳中汲取的能量转化为热能，通过蓄热水箱侧盘管8对蓄热水箱7进行储存热量并保存在水箱之中，通过生活热水给水管11供给用户生活热水。When there is sufficient sunlight on a sunny day, the solar collector 6 converts the energy drawn from the sun into heat energy. The heat is stored in the hot water storage tank 7 through the side coil 8 of the hot water storage tank and stored in the water tank. Through domestic heat The water supply pipe 11 supplies users with domestic hot water.
当连续阴雨天气出现时，仅依靠太阳能加热蓄热水箱7无法满足用户的生活热水的需求时，水源热泵作为辅助热源加热蓄热水箱供给用户生活热水。此时第一温控阀V1、球阀V2、V4、V6、V9、V10开启；球阀14-V3、V5关闭。When continuous rainy weather occurs and only relying on solar energy to heat the hot water storage tank 7 cannot meet the user's demand for domestic hot water, the water source heat pump is used as an auxiliary heat source to heat the hot water storage tank to supply the user with domestic hot water. At this time, the first temperature control valve V1 and the ball valves V2, V4, V6, V9, and V10 are opened; the ball valves 14-V3 and V5 are closed.
初冬供暖状态：当室内温度低于18℃并且蓄热水箱中的温度高于50℃时，此时室外温度不是特别低，室内所需热负荷不高，蓄热水箱7可以直接通过蓄热水箱末端测盘管7对室内进行供暖，仅仅依靠蓄热水箱就可以完全承担室内负荷。此时第二温控阀V7、球阀V8开启；第一温控阀V1、球阀V2、V3、V4、V5、V6、V9、V10关闭。Heating status in early winter: When the indoor temperature is lower than 18°C and the temperature in the hot water storage tank is higher than 50°C, the outdoor temperature is not particularly low at this time and the required indoor heat load is not high. The hot water storage tank 7 can be directly heated by the water storage tank. The coil 7 at the end of the hot water tank heats the room, and the hot water storage tank alone can fully bear the indoor load. At this time, the second temperature control valve V7 and ball valve V8 are open; the first temperature control valve V1 and ball valves V2, V3, V4, V5, V6, V9, and V10 are closed.
中冬供暖状态：当室内温度低于18℃并且蓄热水箱中的温度低于50℃，室外温度高于-5℃时，空气源热泵自动开启，通过吸收环境空气中的低位热能，利通过少量电能驱动压缩机运转进行供暖，从而满足农宅冬季采暖的需求。此时第一温控阀V1、球阀V2、V3、V5开启；第一温控阀V7、球阀V4、V6、V8、V9、V10关闭。Mid-winter heating status: When the indoor temperature is lower than 18°C, the temperature in the hot water storage tank is lower than 50°C, and the outdoor temperature is higher than -5°C, the air source heat pump automatically turns on and absorbs the low-level heat energy in the ambient air. A small amount of electricity is used to drive the compressor to operate for heating, thereby meeting the heating needs of farmhouses in winter. At this time, the first temperature control valve V1 and the ball valves V2, V3 and V5 are opened; the first temperature control valve V7 and the ball valves V4, V6, V8, V9 and V10 are closed.
深冬供暖状态：当室外冬季温度低于-5℃时，鉴于在低温环境下，空气源热泵可能会出现结霜、运行效率下降等一系列问题，而采暖效果不佳。则开启阀门第一温控阀V1、球阀V2、V4、V6、V9、V10；关闭第二温控阀V7、球阀V3、V5、V8，使得热泵的热源转变为蓄热水箱10中的热水，使得热泵机组可以在较高的温度下运行，进而使制冷剂在相对较高的温度中吸热蒸发，提高供暖效果，保证室内温度。Deep winter heating status: When the outdoor winter temperature is lower than -5°C, in view of the low temperature environment, the air source heat pump may have a series of problems such as frosting and reduced operating efficiency, and the heating effect is not good. Then open the first temperature control valve V1, ball valves V2, V4, V6, V9, V10; close the second temperature control valve V7, ball valves V3, V5, V8, so that the heat source of the heat pump is converted into the heat in the hot water storage tank 10 Water allows the heat pump unit to operate at a higher temperature, thereby allowing the refrigerant to absorb heat and evaporate at a relatively high temperature, improving the heating effect and ensuring the indoor temperature.
本发明的有益效果：本发明采用清洁能源的同时，保证了供暖需求，改善了机组的制热性能系数，提高了换热效率，而且保证了用户一年四季的热水供应。通过采用双热源热泵与太阳能联合供暖的方式解决了空气源热泵在供暖工程中容易结露，换热效率低的难题，使得煤改电的策略得以顺利进行。Beneficial effects of the present invention: while using clean energy, the present invention ensures the heating demand, improves the heating performance coefficient of the unit, increases the heat exchange efficiency, and ensures the hot water supply for users all year round. By using dual heat source heat pumps and solar combined heating, the problem of air source heat pumps being prone to condensation and low heat exchange efficiency in heating projects has been solved, allowing the coal-to-electricity strategy to proceed smoothly.

The solar collector 6 converts the energy drawn from the sun into thermal energy, and stores the heat in the hot water storage tank 7 through the solar-hot water storage tank side coil 8 and keeps it in the water tank, and through the domestic hot water supply pipe 11 Provide users with domestic hot water.
当室外温度低于第一设定温度，同时高于第二设定温度时，对应连续阴雨天气出现；仅依靠太阳能加热蓄热水箱7无法满足用户的生活热水的需求时，水源热泵作为辅助热源加热蓄热水箱供给用户生活热水，第一温控阀V1、球阀V2、V4、V6、V9、V10开启；球阀V3、V5关闭。When the outdoor temperature is lower than the first set temperature and higher than the second set temperature, it corresponds to continuous rainy weather; when relying solely on solar energy to heat the hot water storage tank 7 cannot meet the user's demand for domestic hot water, the water source heat pump can be used as a The auxiliary heat source heats the hot water tank to supply domestic hot water to the user. The first temperature control valve V1 and the ball valves V2, V4, V6, V9, and V10 are opened; the ball valves V3 and V5 are closed.
当室外温度低于第二设定温度，同时高于第三设定温度时，对应初冬供暖状态，内温度低于18℃并且蓄热水箱中的温度高于50℃时，此时室外温度不是特别低，室内所需热负荷不高，蓄热水箱7可以直接通过蓄热水箱-末端测盘管7对室内进行供暖，仅仅依靠蓄热水箱就可以完全承担室内负荷。蓄热水箱通过蓄热水箱-末端测盘管向用户侧装置提供热能，第二温控阀V7、球阀1V8开启；第一温控阀V1、球阀1V2、V3、V4、V5、V6、V9、V10关闭。When the outdoor temperature is lower than the second set temperature and higher than the third set temperature at the same time, it corresponds to the early winter heating state. When the internal temperature is lower than 18°C and the temperature in the hot water tank is higher than 50°C, the outdoor temperature at this time It is not particularly low, and the heat load required indoors is not high. The hot water storage tank 7 can directly heat the room through the hot water storage tank-end measuring coil 7. The indoor load can be fully borne by the hot water storage tank alone. The hot water storage tank provides heat energy to the user-side device through the hot water storage tank-end measuring coil. The second temperature control valve V7 and ball valve 1V8 are opened; the first temperature control valve V1, ball valves 1V2, V3, V4, V5, V6, V9 and V10 are closed.
当室外温度低于第三设定温度，同时高于第四设定温度时，对应中冬供暖状态，室内温度低于18℃并且蓄热水箱中的温度低于50℃，室外温度高于-5℃时，空气源热泵自动开启，通过吸收环境空气中的低位热能，利通过少量电能驱动压缩机运转进行供暖，从而满足农宅冬季采暖的需求，第一温控阀V1、球阀V2、V3、V5开启；第二温控阀V7、球阀1V4、V6、V8、V9、V10关闭。When the outdoor temperature is lower than the third set temperature and higher than the fourth set temperature at the same time, corresponding to the mid-winter heating state, the indoor temperature is lower than 18°C and the temperature in the hot water tank is lower than 50°C, and the outdoor temperature is higher than At -5°C, the air source heat pump automatically turns on. By absorbing the low-level heat energy in the ambient air, a small amount of electric energy is used to drive the compressor to operate for heating, thereby meeting the winter heating needs of farmhouses. The first temperature control valve V1, ball valve V2, V3 and V5 are open; the second temperature control valve V7 and ball valve 1V4, V6, V8, V9 and V10 are closed.
当室外温度低于第四设定温度，同时高于第五设定温度时，对应深冬供暖状态，室外冬季温度低于-5℃时，鉴于在低温环境下，空气源热泵可能会出现结霜、运行效率下降等一系列问题，而采暖效果不佳，开启第一类温控阀V1、球阀V2、V4、V6、V9、V10；关闭第一类温控阀V7、球阀V3、V5、V8，使得双热源热泵机组的热源转变为蓄热水箱中的热水，使得双热源热泵机组可以在较高的温度下运行，进而使制冷剂在相对较高的温度中吸热蒸发，提高供暖效果，保证室内温度。When the outdoor temperature is lower than the fourth set temperature and higher than the fifth set temperature, it corresponds to the deep winter heating state. When the outdoor winter temperature is lower than -5℃, in view of the low temperature environment, the air source heat pump may freeze. If there are a series of problems such as frost and reduced operating efficiency, and the heating effect is not good, open the first type thermostatic valve V1, ball valve V2, V4, V6, V9, V10; close the first type thermostatic valve V7, ball valve V3, V5, V8, the heat source of the dual heat source heat pump unit is converted into hot water in the hot water storage tank, so that the dual heat source heat pump unit can operate at a higher temperature, thereby allowing the refrigerant to absorb heat and evaporate at a relatively high temperature, improving Heating effect to ensure indoor temperature.
本发明的有益效果是采用清洁能源的同时，保证了供暖需求，改善了机组的制热性能系数，提高了换热效率，而且保证了用户一年四季的热水供应。通过采用双热源热泵与太阳能联合供暖的方式解决了空气源热泵在供暖工程中容易结露，换热效率低的难题，使得煤改电的策略得以顺利进行。The beneficial effects of the present invention are that while using clean energy, the heating demand is ensured, the heating performance coefficient of the unit is improved, the heat exchange efficiency is increased, and hot water supply for users is ensured all year round. By using dual heat source heat pumps and solar combined heating, the problem of air source heat pumps being prone to condensation and low heat exchange efficiency in heating projects has been solved, allowing the coal-to-electricity strategy to proceed smoothly.
