【摘要】：本文以家用生活热水供给为研究对象,为达到即开即用以及节能节水的目的,分析论证多种热源的集成组合供热方式和优化配置,针对别墅型住宅需求,设计了一套家用生活热水供给集成控制系统。首先,本文通过从能源热价、设备成本、供热效果以及安全环保等各个方面比较太阳能集热器、空气源热泵、电热水器以及燃气热水器的优缺点,论证确定了两种优化配置方案,一种是太阳能集热器与燃气热水器组合供热,另一种是空气源热泵与燃气热水器组合供热。采用这两种组合供热方式,能够保证用户使用舒适的前提下,达到节能的目的。其次,通过分析传统家用生活热水系统中存在的浪费水和热能的现象,加装了回水管路、循环泵、电磁阀以及温度传感器等器件,形成了多热源优化配置的家用生活热水集成供给系统,并通过本文所设计的控制器实现了生活热水的即开即用与节能节水。最后,本文设计了两种控制器:PLC(Programmable Logic Controller)控制器和单片机控制器,以满足不同用户的使用需求。其中,设计PLC控制器的主要工作包括PLC的选型、控制流程的制定、控制程序的编写以及仿真调试,而设计单片机控制器的主要工作是电气工作原理的设计、电气元器件的选型、电路板的制作以及单片机程序开发,并通过模拟仿真验证了系统的控制功能能够满足使用要求。
[Abstract]:In this paper, the supply of domestic domestic hot water is taken as the research object, and in order to achieve the purpose of immediate use and energy saving and water saving, this paper analyzes and demonstrates the integrated combined heating mode and optimal configuration of various heat sources, aiming at the demand of villa house.An integrated control system for domestic hot water supply is designed.First of all, this paper compares the advantages and disadvantages of solar collector, air source heat pump, electric water heater and gas water heater from the aspects of energy thermal price, equipment cost, heating effect and safety and environmental protection.Two optimal configuration schemes are determined, one is the combination of solar collector and gas water heater, the other is the combination of air source heat pump and gas water heater.By adopting these two combined heating methods, the energy saving can be achieved on the premise that the users are comfortable to use.Secondly, by analyzing the phenomenon of waste water and heat energy in the traditional domestic hot water system, the backwater pipeline, circulating pump, solenoid valve and temperature sensor are added.The integrated domestic hot water supply system with multi-heat source optimization is formed, and through the controller designed in this paper, it is realized that the domestic hot water can be used immediately and energy saving and water saving can be realized by the controller designed in this paper.At last, this paper designs two kinds of controllers: PLC programmable Logic controller and MCU controller to meet the needs of different users.Among them, the main work of designing PLC controller includes the selection of PLC, the formulation of control flow, the compilation of control program and the simulation and debugging, while the main work of designing MCU controller is the design of electrical working principle and the selection of electrical components.The manufacture of circuit board and the development of single chip microcomputer program, and the simulation results show that the control function of the system can meet the requirements.
