【摘要】：国内家用热泵空调器能耗和生活热水能耗日益升高，已经成为两项最大的建筑能耗。本文基于夏季空调冷凝热回收制取生活热水的原理，提出了一个具有7种独立运行模式，可全年连续运行的多功能家用热泵空调器。7种运行模式分别为：单独制冷、制冷兼制热水、单独制热水、单独供热、供热兼制热水、除湿和除霜模式。一机多用，提高了设备利用率，且节约能耗、减少环境污染。分析了现有一些空调热水系统存在的问题，介绍了多功能家用热泵空调系统原理，并进行了理论计算，设计出了各个模式的系统运行流程，，对系统各个部件进行了匹配计算，并给出了经验公式，方便以后产品的系列化生产。搭建了实验系统，依照实验方案，对系统进行了测试，如可行性、可靠性及系统启动、运行特性等等。并根据测试仪器精度，分析了系统测试中产生的误差。通过实验，确定了实验系统的运行模式并完善了相应的控制策略。实验结果表明，在合理的控制策略下，该多功能家用热泵空调器是可以连续稳定运行的。既能满足全年制冷、供热、除湿等功能，又能提供生活热水，同时还有夜间低能耗模式。该系统具有性能系数COP高，启动快，夏季制热水时间短等优点。因此，本文所设计的适合家庭使用的多功能家用热泵空调器具有广阔的市场前景。由于实验条件和时间等因素的限制，导致本文的实验还存在一些不足之处，实验系统参数的精确定量测量以及除霜时间的确定等还需要进一步测试和研究。但本文的目的在于验证空调冷凝热回收制取生活热水的可行性，为多功能家用热泵空调器的生产提供理论依据，为产品市场化提供参考。本课题为“十二五”国家科技支撑计划项目课题《典型气候区既有居住建筑绿色化改造技术研究与工程示范》（No.2012BAJ06B02）的部分内容。
[Abstract]:The energy consumption of domestic domestic heat pump air conditioner and the energy consumption of domestic hot water are rising , which has become the two largest energy consumption . In this paper , a multi - function domestic heat pump air conditioner with 7 independent operating modes and continuous operation in the whole year is put forward . This paper analyzes the existing problems of some existing air - conditioning hot - water systems , introduces the principle of multi - function domestic heat pump air - conditioning system , and makes theoretical calculation , designs the system operation flow of each mode , calculates the matching of each part of the system , and gives the experimental system . According to the experimental scheme , the system is tested , such as feasibility , reliability , system startup , operating characteristics , etc . The error generated in the system test is analyzed according to the accuracy of the test instrument . The experimental results show that the multi - function domestic heat pump air conditioner can be operated continuously and stably under a reasonable control strategy . The experimental results show that the multi - function domestic heat pump air conditioner has the advantages of high performance coefficient COP , quick start - up , short hot water heating time and the like under the reasonable control strategy , and therefore , the multifunctional domestic heat pump air conditioner designed by the household heat pump has wide market prospect . Due to the limitations of experimental conditions and time factors , there are some shortcomings in the experiment , the precise quantitative measurement of experimental system parameters and the determination of defrosting time need further testing and research , but the purpose of this paper is to verify the feasibility of the heat recovery of air conditioning condensation heat recovery and provide theoretical basis for the production of multi - functional domestic heat pump air conditioner . This project is part of the research and engineering demonstration project ( No.2012BAJ06B02 ) for the project of the National Science and Technology Support Plan Project of the 12th Five - Year Plan .
