【摘要】：地源熱泵技術(shù)作為一種既可以制冷又可以供熱的空調(diào)技術(shù),由于在節(jié)能方面有著獨(dú)特的優(yōu)勢(shì),近年來,地源熱泵系統(tǒng)迅速發(fā)展。在地源熱泵快速發(fā)展的同時(shí),它的實(shí)際運(yùn)行效率卻往往被忽略,性能檢測(cè)能有效的檢測(cè)系統(tǒng)運(yùn)行的情況,為改進(jìn)控制方案、提高設(shè)計(jì)精度及改善運(yùn)行效率提供可靠的數(shù)據(jù)。 對(duì)空調(diào)系統(tǒng)而言,實(shí)際運(yùn)行的絕大部分時(shí)間并不是在名義工況下運(yùn)行的,況的改變必然引起系統(tǒng)能效的變化。通過測(cè)試可以得到空調(diào)系統(tǒng)的運(yùn)行參數(shù)及性能系數(shù),但是每個(gè)參數(shù)的改變都將引起系統(tǒng)性能及能耗的變化。了解這些因素對(duì)系統(tǒng)的影響,有助于提高系統(tǒng)的運(yùn)行效率,使其維持在高效運(yùn)行狀態(tài),以達(dá)到節(jié)能的目的。 本文首先研究了空調(diào)系統(tǒng)運(yùn)行過程中,能夠有效反應(yīng)機(jī)組和系統(tǒng)能效的相關(guān)參數(shù)的檢測(cè)理論和方法�；诳照{(diào)系統(tǒng)運(yùn)行能效的概念,在明確運(yùn)行能效影響因素及其變化特征的基礎(chǔ)上,找出在空調(diào)系統(tǒng)運(yùn)行過程中,可以準(zhǔn)確反映空調(diào)各子系統(tǒng)和整個(gè)空調(diào)系統(tǒng)運(yùn)行能效的參數(shù),提出適用于空調(diào)工程現(xiàn)場(chǎng)能效檢測(cè)的方法,包括測(cè)試條件、儀器、過程、內(nèi)容,以及在測(cè)試過程中可能遇到的問題及解決辦法,為地源熱泵系統(tǒng)的能效分析、評(píng)價(jià)奠定基礎(chǔ)。 然后,以理論分析為基礎(chǔ),提煉出影響地埋管地源熱泵系統(tǒng)性能的因素,分別將部分負(fù)荷率、負(fù)荷側(cè)變溫差變流量、地源側(cè)變流量等作為獨(dú)立變量,分析了這些因素對(duì)機(jī)組和系統(tǒng)的影響,為系統(tǒng)的優(yōu)化運(yùn)行提供理論依據(jù)。 最后,建立空調(diào)機(jī)組的數(shù)學(xué)模型,模擬了負(fù)荷率和流量等因素對(duì)機(jī)組性能的影響,得出模擬曲線及公式,然后通過工程實(shí)測(cè)驗(yàn)證了模擬結(jié)果的準(zhǔn)確性。
[Abstract]:Ground-source heat pump (GSHP) technology is a kind of air conditioning technology which can be used for refrigeration and heating. Because of its unique advantages in energy saving, ground-source heat pump system has developed rapidly in recent years. With the rapid development of ground-source heat pump, its actual operating efficiency is often neglected, and the performance detection can effectively detect the operation of the system, which provides reliable data for improving the control scheme, improving the design accuracy and improving the operational efficiency. For air conditioning systems, most of the actual operation time is not in nominal operating conditions, the change of conditions will inevitably lead to changes in system energy efficiency. The operating parameters and performance coefficients of air conditioning system can be obtained by testing, but the change of each parameter will cause the change of system performance and energy consumption. Understanding the influence of these factors on the system is helpful to improve the efficiency of the system and keep it in the state of efficient operation so as to achieve the purpose of energy saving. In this paper, the theory and method of measuring the energy efficiency parameters of air conditioning system are studied. Based on the concept of operating energy efficiency of air conditioning system and on the basis of defining the influencing factors and their changing characteristics of operating energy efficiency, this paper finds out that the operating energy efficiency parameters of each subsystem and the whole air conditioning system can be accurately reflected in the operation of air conditioning system. This paper puts forward the methods of energy efficiency measurement in the field of air conditioning engineering, including test conditions, instruments, processes, contents, problems that may be encountered in the testing process and their solutions, which will lay a foundation for energy efficiency analysis and evaluation of ground-source heat pump systems. Then, based on the theoretical analysis, the factors influencing the performance of the ground source heat pump system are extracted. The partial load rate, the load side temperature difference variable flow, the ground source side variation flow rate and so on are regarded as independent variables, respectively. The influence of these factors on the unit and system is analyzed, which provides the theoretical basis for the optimal operation of the system. Finally, the mathematical model of the air conditioning unit is established, the influence of load rate and flow rate on the performance of the unit is simulated, the simulation curve and formula are obtained, and the accuracy of the simulation results is verified by the engineering measurement.
