摘要:能源是人類面臨的重要問題之一，其中能源的不合理開發(fā)利用，以及能源消耗排放對(duì)環(huán)境造成的污染，這些問題對(duì)人們的生活環(huán)境造成了很大的影響，使得節(jié)能減排成為世界各國(guó)關(guān)注的一個(gè)重要課題。而總所周知，建筑節(jié)能是實(shí)現(xiàn)環(huán)境保護(hù)和節(jié)約能源的一個(gè)主要途徑，其中暖通空調(diào)的能量消耗在建筑能耗中占著很大的比重，壓縮冷凝機(jī)組作為暖通空調(diào)的一個(gè)重要組成部分，由制冷壓縮機(jī)、冷凝器及必要的輔助設(shè)備（不含蒸發(fā)器和節(jié)流裝置）所組成的裝置，機(jī)組的性能與空調(diào)的制冷效率有著很大的關(guān)聯(lián)，因此提高壓縮冷凝機(jī)組的效率可以在一定程度上降低空調(diào)的能源消耗量，以達(dá)到節(jié)能減排的目標(biāo)。 本課題以第二制冷劑量熱器法為測(cè)試方法，設(shè)計(jì)能測(cè)試制冷量范圍為2~10kW的風(fēng)冷壓縮冷凝機(jī)組性能的試驗(yàn)室，為被測(cè)制冷壓縮冷凝機(jī)組提供能確保冷凝溫度、蒸發(fā)溫度等工況條件的設(shè)施，對(duì)制冷壓縮冷凝機(jī)組的性能參數(shù)進(jìn)行測(cè)試分析，計(jì)算被測(cè)機(jī)組的制冷量，并比較壓縮機(jī)的輸入功率來檢測(cè)機(jī)組的性能。與此同時(shí)，試驗(yàn)室除了要實(shí)現(xiàn)自動(dòng)化操作、運(yùn)行穩(wěn)定和控制精度高等指標(biāo)外，試驗(yàn)裝置的節(jié)能與否也已成為性能試驗(yàn)室的重要衡量標(biāo)準(zhǔn)。通過試驗(yàn)室的測(cè)試便可選出性能更高的風(fēng)冷壓縮冷凝機(jī)組，便于更節(jié)能的空調(diào)的制造，為節(jié)能減排作出一份貢獻(xiàn)。 關(guān)鍵詞：焓差法試驗(yàn)室，風(fēng)冷壓縮冷凝機(jī)組，第二制冷劑量熱器
Abstract:Energy is an important one of the problems facing mankind, energy is not rational development and utilization, and the discharge of energy consumption of the environmental pollution from these problems in people's living environment caused a great influence on the energy reduction in the world to focus on an important subject. and it is well-known that，Building energy conservation is to achieve environmental protection and conservation of energy, a major means of air conditioning, heating and energy consumption of energy consumption in the construction of a large proportion of being, to compress and air conditioning units as an important part of the compressor and the condensers of refrigeration and the necessary subsidiary device （ does not include the evaporator and throttling device ） a device, The performance with air conditioning refrigeration efficiency has a large, thereby improving the efficiency of being cut down a certain extent reduce the supply of energy, energy conservation amount consumed to achieve emissions reduction goal. This subject in the second refrigerant the amount of heat exchanger law as the testing methods, design can test refrigerating capacity to 2 ~ 10kW air- compression is condensation, the crew of the laboratory to be cooling down for being able to ensure that being the temperature, and vaporize temperature and other conditions in terms of facilities for compressing and cooling condensation, the crew of the performance of the parameter testing analysis, the crew to be of a compressor refrigerating capacity, and the input power to see the performance. At the same time, the laboratory in addition to implement automation operation, high precision, stability and control, test the indicators for energy also has become important to the laboratory performance criteria. pass the test laboratory and selected performance higher the air-compression for more energy efficient condensation, the air conditioning made for energy reduction make a contribution. Key words: Enthalpy by the lab, positive displacement referigerant compressor, secondary refrigerant calorimete |
