采用氨水溶液的先进蓄能系统工作特性研究(1)——工作原理及过程动态模型

对采用氨水溶液的变质量能量转换及储存系统的工作原理、工作循环和流程进行介绍。由于蓄能系统的能量转换过程是一个与时间有关的动态过程,常规的稳态制冷/热泵循环热力计算方法已不再适用,需给出一种新的动态热力计算方法。通过数值模拟来了解先进蓄能系统的工作特性,为进一步研究、开发该蓄能系统奠定理论基础。

THEORETICAL RESEARCH ON THE WORKING CHARACTERISTICS OF AN ADVANCED ENERGY STORAGE SYSTEM USING NH3-H2O AS WORKING FLUID, PART ( 1 )——WORKING PRINCIPLE DESCRIPTION AND MODELING

The variable mass electricity transformation and storage(VMETS) system using aqueous ammonia as working fluid has large working temperature range.It can be applied not only for air-conditioning system in summer and heat pump heating system in winter,but also for the living hot water supplying system all year long,which can shift peak load efficiently.The working principle,cycle and flow of the VMETS system have been introduced firestly.Since the energy transformation process of the system is dynamic,the tradition static thermal calculation methods of the refrigeration or heat pump system are not suitable for the VMETS system.The dynamic thermodynamic models for the system were developed by the computer numerical simulation,the working characteristics of the system could be known,which is very helpful for further researching and developing the system.
