【摘要】：空调产品的性能试验是整个产品的生产制造过程中能耗最大的一个环节,如何降低性能试验环节的能耗,是降低空调制造行业能耗的关键点之一。本文针对国内外传统性能实验台的设计方法进行分析,对常规性能实验台的能耗进行分类汇总,并以特灵空调系统(中国)有限公司投建的大型风冷冷水(热泵)机组性能实验台为研究对象,完成了机组性能实验,验证了试验台的节能特性,为行业内同类型实验台的系统节能设计提供了参考。本文的主要研究内容包括:(1)分析了常规性能实验台的能耗规律,包括被测机组的电功率输入,为维护恒定的水温和水流量而向实验台系统输入的能量,为维护测试间被测机环境的温度和湿度工况而向实验台系统输入的能量。发现其中后两项,无论在被测机组运行制冷工况还是制热工况时,都是相对立的,一项的输入能量为冷量时另一项则为热量,因此,从能量转移和守恒的角度,这两项可以互为补充,进行平衡抵消。(2)对常规制冷机组性能实验台能耗进行了详细计算,发现常规性能实验台在进行性能试验时,实验台所消耗的能量为被试机组制冷量的2.59倍以上。(3)通过能量平衡和控制优化实现了性能实验台的节能设计,包括:①节能实验台的测试水系统温度和流量控制;②节能实验台环境温度控制原理;③节能实验台环境湿度控制原理,④节能实验台恒温水箱温度控制。并阐明了节能设计性能实验台的实现方法和控制原理。(4)完成了性能实验台测试间的气流组织优化设计,满足测试间内温度场和速度场的要求;完成了空气处理箱、管道系统、辅助冷水机组、压缩冷凝机组、蒸汽、冷却塔、水泵、板式换热器等系统部件的设计计算;完成了温度、湿度、功率、流量等参数的测量系统和测试软件的开发。(5)对节能设计性能实验台分析和验证表明,研究的节能设计性能实验台的能耗约为被测机制冷量的1.12倍左右;对机组在AHRI标准100%和25%负荷条件下进行了试验,结果验证了设计的合理性和节能性。
[Abstract]:The performance test of air conditioning products is one of the most energy-consuming links in the whole production and manufacturing process. How to reduce the energy consumption of the performance test link, It is one of the key points to reduce the energy consumption in the air conditioning manufacturing industry. This paper analyzes the design methods of the traditional performance test bench at home and abroad, and classifies the energy consumption of the conventional performance test bench. The performance experiment of large air-cooled chilled water (heat pump) unit built by Thaling Air conditioning system (China) Co., Ltd was studied. The performance experiment of the unit was completed, and the energy saving characteristics of the test bench was verified. The main research contents of this paper include: 1) analyzing the rule of energy consumption of the conventional performance test bench, including the power input of the unit to be tested, and providing a reference for the system energy saving design of the same type of test bench in the industry. In order to maintain the constant water temperature and water flow rate, the energy input to the test bench system and the energy input to the test bed system to maintain the temperature and humidity working conditions of the machine being tested in the test room are also found. The last two items are found. Both the refrigeration and heating conditions of the unit under test are opposite, and the input energy of one item is the heat when the input energy is the cooling quantity. Therefore, from the point of view of energy transfer and conservation, these two terms can complement each other. The energy consumption of the conventional refrigeration unit performance test bench is calculated in detail. It is found that the conventional performance test bench is carrying out the performance test. The energy consumption of the test bench is more than 2.59 times of the refrigerating capacity of the tested unit, and the energy balance and control optimization are used to realize the energy-saving design of the performance test bench. This paper includes the temperature and flow control of water system and flow control of water system. The principle of environmental temperature control of energy saving test bench and the principle of environmental humidity control of energy saving test bench. The temperature control of constant temperature water tank on energy saving test bench is expounded. The realization method and control principle of the performance test bench are designed. The design and calculation of air handling box, pipeline system, auxiliary chiller, compression condenser, steam, cooling tower, water pump, plate heat exchanger and so on have been completed. The development of measuring system and testing software of humidity, power and flow rate shows that the energy consumption of the test bench is about 1.12 times of the cooling capacity of the machine under test. The tests were carried out on the AHRI standard 100% and 25%, and the results show that the design is reasonable and energy saving.
