Description
技术领域 technical field
本发明涉及一种利用夏季冰蓄冷运行释放的冷凝热作为热源的蓄卫生热水系统；冬季利用可再生能源作热源的蓄采暖水和卫生热水形式的节能空调装置，具体说是一种冰蓄冷蓄热超低温热泵空调。The invention relates to an energy-saving air-conditioning device in the form of stored heating water and sanitary hot water using renewable energy as a heat source in winter, specifically an ice Cold storage heat storage ultra-low temperature heat pump air conditioner.
背景技术 Background technique
目前，为了节能减排，世界发达国家的冰蓄冷空调技术传入中国，并得到长足地发展。冰蓄冷空调技术不但节省了空调运行费用，对电力部门削峰填谷，平衡电力负荷起到一定的作用，其社会效益重大；然而世界现有技术的冰蓄冷空调运行过程中，制冷机组的冷凝器通过冷却塔将冷凝热量排放至空气中，白白地浪费了大量热能。例如宾馆、酒店、洗浴中心、医院等单位，在冰蓄冷空调制冷的同时，往往渴望其能够通过冷凝的热量进行加热，提供所需的热水供洗浴采暖之用，但现在这些单位为了提供卫生热水和供暖，大都另外安装一套制热系统制取卫生热水和采暖热水，或是采用热力公司的商品蒸气或采用电锅炉和燃气、燃油锅炉等方式，这样一来，不但增加了许多运营成本，还造成了资源浪费。At present, in order to save energy and reduce emissions, ice storage air-conditioning technology from developed countries in the world has been introduced into China and has been greatly developed. Ice-storage air-conditioning technology not only saves the cost of air-conditioning operation, but also plays a certain role in power sector load shifting and balancing power loads. Its social benefits are significant; The condenser discharges the condensation heat into the air through the cooling tower, wasting a lot of heat energy in vain. For example, hotels, hotels, bathing centers, hospitals and other units often hope that they can be heated by condensed heat to provide the required hot water for bathing and heating while the ice storage air conditioner is cooling. For hot water and heating, most of them install another heating system to produce sanitary hot water and heating hot water, or use commercial steam from heating companies or use electric boilers, gas, and oil-fired boilers. Many operating costs, but also caused a waste of resources.

Coupling the heat exchange circuit, through the heating water heat storage coupling circulation pump 41, the condensation heat is released to the super high temperature water source heat pump 16. The primary water side of the evaporator 20 stores heat for the heating water system. The path is: the heating water storage The thermally coupled circulation pump 41 passes through the primary water side of the evaporator 20 to the coupling tank 15, passes through the coupling tank 15, and then uses the heating water to store heat and couple the circulating pump 41 to repeat the above to release the condensation heat generated during the ice storage operation to the super high temperature of the subsequent stage. Water source heat pump 16. After the refrigerant on the secondary side of the evaporator 20 evaporates and absorbs the heat of condensation on the primary side, the refrigerant gas is inhaled and compressed by the refrigeration compressor 17, and the discharged high-temperature gas passes through the condenser 18 to release heat from the primary to the secondary condensation. The heat storage of heating water is carried out by heating water heat storage circulation pump 22 passing through the secondary water side of condenser 18, then passing through heating water heat storage tank 21 to heating water heat storage circulation pump 22 to form a heating water heat storage cycle run. The heat storage process of sanitary hot water is: the sanitary hot water heat storage coupled circulation pump 43 passes through the primary water side of the evaporator 47 to the coupling tank 15, and then passes through the sanitary hot water heat storage coupled circulation pump 43 to store heat for the sanitary hot water system. The process is: the condensation heat is coupled to the secondary refrigerant side through the primary water side of the evaporator 47, and after being evaporated and absorbed by the secondary refrigerant, the gas is sent to the refrigeration compressor 44 and the high-temperature gas compressed by the compressor passes through the condenser 45 The heat storage of sanitary hot water is carried out by heat release from primary to secondary condensation. The process is as follows: from the sanitary hot water heat storage circulation pump 48 through the secondary water side of the condenser 45 to the sanitary hot water heat storage tank 23 and then through the sanitary hot water storage The heat circulation pump 48 stores heat in the sanitary hot water, and the sanitary hot water supplies the sanitary hot water to the bath nozzle 25 through the sanitary hot water output pump 24 .
前级超低温水源热泵9经冷凝器11放热后其制冷剂液体由膨胀阀12节流后至蒸发器13的二次侧蒸发吸收一次循环的冰蓄冷水中的热量，对冰蓄冷槽罐1的水蓄冰运行，其蓄冰过程是：由喷淋液循环泵8经蒸发器13的一次水侧将冰蓄冷槽罐1中的水送入蒸发器13，被二次制冷剂蒸发吸热制冷，过冷的冰水由冰蓄冷阀门5至冰蓄冷槽罐1再由冰蓄冷阀门6至喷淋液循环泵8构成冰蓄冷循环运行回路，最终将冰蓄冷槽罐1内的水制冷成为0℃左右的冰水，再由空调输出系统e向空调系统供冷空调运行，其过程是：由冰蓄冷输出循环泵28经冰蓄冷输出换热器27的一次至冰蓄冷槽罐1，再经冰蓄冷槽罐1至喷淋液循环泵8重复上述由冰蓄冷输出换热器27的一次向二次输出冰蓄冷的冷量，再由空调输出循环泵29经蓄冷蓄热输出转换阀门31至冰蓄冷输出换热器27的二次经蓄冷蓄热输出转换阀门32至风机盘管30经空调输出循环泵29利用冰蓄冷的冷量经风机盘管30向室内制冷空调运行。After the front-stage ultra-low temperature water source heat pump 9 releases heat through the condenser 11, its refrigerant liquid is throttled by the expansion valve 12 and evaporates to the secondary side of the evaporator 13 to absorb the heat of the ice-storage cold water in the first cycle. Water ice storage operation, the ice storage process is: the water in the ice cold storage tank 1 is sent to the evaporator 13 by the spray liquid circulation pump 8 through the primary water side of the evaporator 13, and is evaporated by the secondary refrigerant to absorb heat and cool , the supercooled ice water is from the ice storage valve 5 to the ice storage tank 1, and then from the ice storage valve 6 to the spray liquid circulation pump 8 to form an ice storage cycle operation loop, and finally the water in the ice storage tank 1 is refrigerated to 0 The ice water at about ℃ is supplied to the air-conditioning system by the air-conditioning output system e for cooling and air-conditioning. The ice storage tank 1 to the spray liquid circulation pump 8 repeats the above-mentioned primary to secondary output of ice storage cooling capacity from the ice storage output heat exchanger 27, and then the air conditioner output circulation pump 29 passes through the cold storage heat storage output conversion valve 31 to The secondary heat storage output heat exchanger 27 passes through the cold storage heat storage output conversion valve 32 to the fan coil unit 30, and then the air conditioner output circulation pump 29 utilizes the cooling capacity of the ice storage unit to run the indoor cooling air conditioner through the fan coil unit 30.

The high-temperature gas in the condenser 11 first condenses and releases heat to the coupling heat exchange circuit on the secondary water side to store heat for the heating and sanitary hot water heat storage system. The process is the same as the above-mentioned heat storage process during summer cold storage. When ice is stored, the condensation heat released by the front-stage ultra-low temperature water source heat pump 9 is greater than the heat required for the sanitary hot water heat storage operation, and the excess condensation heat is transferred from the cooling circulation pump 39 to the spray liquid type wind energy heat exchange tower 2 through the cooling valve 53 The nozzle 56 sprays mist cooling water to cool and exchange heat with the wind entering through the air inlet 58, and the cooling water returns to the coupling tank 15 through the cooling valve 54, completing the operation circuit of discharging the remaining cooling capacity. The antifreeze in the spray liquid type wind energy heat exchange tower 2 in summer is completely discharged into the antifreeze liquid circulation liquid storage tank 3 through the winter and summer conversion valve 55, and is supplied from tap water to the spray liquid type wind energy heat exchange tower 2 through the clear water injection valve 60.
