技术领域technical field
本发明属于空气压缩式制冷空调技术领域，更具体的说，属于一种利用 空气中的能量进行制冷、制热和提供生活热水的蒸汽压缩和低温热源混合热 泵装置系统。The invention belongs to the technical field of air compression refrigeration and air conditioning, more specifically, it belongs to a vapor compression and low-temperature heat source hybrid heat pump device system that utilizes energy in the air for refrigeration, heating and domestic hot water supply.
背景技术Background technique
空气源热泵空调装置采用蒸汽压缩式制冷循环系统，蒸汽压缩式制冷循 环系统通常利用室外大气中的低品位能源为空调系统提供冷热源的热力设 备，目前空气源热泵已经在住宅和商业建筑中得到了广泛的应用。空气源热 泵空调装置可以制取冷水和热水、并以冷水或热水为介质通过空调末端直接 向房间输送冷风或者热风，以及向房间提供所需要的冷热量以保证房间的热 舒适性。在夏季供冷运行时，空气源热泵空调装置向房间供冷运行时要将大 量的冷凝热排放到室外大气环境中，这样会造成能量损失和环境热污染。在 冬季供热时，空气源热泵空调装置的工作效率急剧降低，当气温降低到一定 程度时空气源热泵空调装置几乎无法正常工作，所以冬季时低温地区使用空 气源热泵空调装置存在经济效益差和运行困难等问题。The air-source heat pump air-conditioning device adopts a vapor compression refrigeration cycle system. The vapor compression refrigeration cycle system usually uses the low-grade energy in the outdoor atmosphere to provide thermal equipment for the air-conditioning system as a cold and heat source. At present, air-source heat pumps have been used in residential and commercial buildings. Has been widely used. The air source heat pump air conditioner can produce cold water and hot water, and use cold water or hot water as the medium to directly deliver cold or hot air to the room through the air conditioner terminal, and provide the required cold heat to the room to ensure the thermal comfort of the room. During the cooling operation in summer, the air source heat pump air conditioner will discharge a large amount of condensation heat to the outdoor air environment when it is operating for cooling the room, which will cause energy loss and environmental thermal pollution. When heating in winter, the working efficiency of the air source heat pump air conditioner decreases sharply. When the temperature drops to a certain level, the air source heat pump air conditioner can hardly work normally. Therefore, the use of air source heat pump air conditioners in low temperature areas in winter has poor economic benefits and Difficulty running etc.
如果在商业建筑或者住宅建筑中同时安装空气源热泵空调装置和热泵热 水器装置的话，会增加建筑的整体设备费用、运行费用及其占用空间。同时 空气源热泵空调装置和热泵热水器装置具有相同的工作原理，如何将空气源 热泵空调装置和热泵热水器装置很好地结合在一起以发挥热泵系统的最大能 效一直是制约本技术领域的一大难题。If an air source heat pump air conditioner and a heat pump water heater are installed simultaneously in a commercial building or a residential building, it will increase the overall equipment cost, operating cost and occupied space of the building. At the same time, the air source heat pump air conditioner and the heat pump water heater have the same working principle. How to combine the air source heat pump air conditioner and the heat pump water heater well to maximize the energy efficiency of the heat pump system has always been a major problem restricting this technical field. .
