【摘要】：隨著社會(huì)經(jīng)濟(jì)的發(fā)展，人們對(duì)居住環(huán)境的要求越來(lái)越高，同時(shí)節(jié)能環(huán)保意識(shí)也不斷增強(qiáng)，水源多聯(lián)機(jī)結(jié)合了多聯(lián)機(jī)技術(shù)和可再生能源的優(yōu)點(diǎn)，現(xiàn)在已得到越來(lái)越多的應(yīng)用。水源多聯(lián)機(jī)在日本技術(shù)已很成熟，但國(guó)內(nèi)對(duì)于水源多聯(lián)機(jī)的研究起步晚，可參考的資料有限，，關(guān)于水源多聯(lián)機(jī)熱特性能查到的資料很少。從這一點(diǎn)出發(fā)，建立了一個(gè)水源多聯(lián)機(jī)的仿真模擬平臺(tái)，并對(duì)水源多聯(lián)機(jī)全年運(yùn)行特性進(jìn)行了模擬分析，分析水源多聯(lián)機(jī)的熱特性。 本文首先將系統(tǒng)中制冷劑、水、空氣的主要參數(shù)程序化，然后對(duì)壓縮機(jī)、膨脹閥、換熱器等系統(tǒng)所需的主要組件合理選擇類(lèi)型后建立物理模型，并對(duì)各模型的計(jì)算流程進(jìn)行了設(shè)計(jì)和描述；本文提出了一種壓縮機(jī)頻率控制制冷劑流量、循環(huán)水量控制室外機(jī)過(guò)冷/熱度的新控制方法，建立了室內(nèi)機(jī)模塊、室外機(jī)模塊等主要模塊，建立了基于TRNSYS的水源多聯(lián)機(jī)仿真平臺(tái)，并對(duì)系統(tǒng)全年的運(yùn)行特性進(jìn)行了模擬分析。模擬結(jié)果表明，水源多聯(lián)機(jī)系統(tǒng)夏季負(fù)荷率為40%-70%時(shí)效率較高，其中負(fù)荷率為60%左右運(yùn)行效率最高，冬季負(fù)荷率為50%-60%時(shí)效率最高；系統(tǒng)額定制熱容量大于制冷容量，且負(fù)荷率一定時(shí)系統(tǒng)制熱效率均高于制冷效率；夏季和冬季系統(tǒng)的平均性能系數(shù)都比較高，全年平均運(yùn)行效率比較高，該系統(tǒng)節(jié)能效果較好。
[Abstract]:With the development of social economy, people have higher and higher requirements for the living environment. Meanwhile, the awareness of energy saving and environmental protection is also increasing. Water resources online combines the advantages of multi-online technology and renewable energy. Now, more and more applications have been made. The technology of water source multi-online is very mature in Japan, but the domestic research on water multi-online has started late, and the reference data is limited. Based on this, a simulation simulation platform is established, and a simulation analysis is carried out on the characteristics of multi-source multi-on-line thermal characteristics in the whole year. The thermal characteristics of multi-line water source are analyzed. In this paper, the main parameters of refrigerant, water and air in the system are programmed firstly, and then the physical model is established after the main components of compressor, expansion valve and heat exchanger are reasonably selected. The calculation flow of each model is designed and described. In this paper, a new control method of compressor frequency controlled refrigerant flow and circulating water is proposed to control the supercooling / heat of outdoor unit. The main modules such as indoor unit module, outdoor unit module and so on are established. A multi-on-line water source simulation platform based on TRNSYS is established, and the operating characteristics of the system throughout the year are simulated and analyzed. The simulation results show that. The efficiency of the system is higher when the load rate is 40% -70% in summer, and the efficiency is the highest when the load rate is about 60%, and the load rate is 50% -60% in winter. The rated heating capacity of the system is larger than the refrigeration capacity, and the heating efficiency of the system is higher than that of the refrigeration when the load rate is constant. The average performance coefficient of the system is higher in summer and winter, and the annual average operating efficiency is higher.
