美优乐MT系列压缩机问世35年，全封闭、活塞式商用制冷压缩机，适用蒸发温度：-45℃--+20℃，制冷工质：R22，R134A，R507，R404A，R502，R407，冷量范围：700•--71000W，主要适用于空调，工业冷水机，冷库等。美优乐MT系列压缩机作为跨临界二氧化碳空调系统效率及可靠性影响最大的部件，应当充分结合二氧化碳超临界循环具体特点重新进行设计。CO2和氨一样，其绝热指数K值较高，达1.30，这可能会使压缩机排气温度偏高，但由于CO2需要的压缩机的压比小，因此不需要对美优乐压缩机本身进行冷却。正因为绝热指数高，压比小，可减小压缩机余隙容积的再膨胀损失，使美优乐压缩机容积效率较高。经过实验和理论研究，往复式压缩机有良好的油膜滑动密封，成为CO2系统的首选。BOCK对其二氧化碳压缩机排气阀进行了改进，排气改良后的二氧化碳压缩机效率提高了7%。型号TE-25-20-15-10-5051015TCP.F.P.A.P.F.P.A.P.F.P.A.P.F.P.A.P.F.P.A.P.F.P.A.P.F.P.A.P.F.P.A.P.F.P.A.MT-283021501.1829501.3538801.5049401.6261501.7175201.7690601.76107901.70127101.574016901.2224501.4133301.5943201.7554601.8967501.9981902.0598102.06116102.015027301.6536601.8747002.0658902.2372202.3687202.44103902.486038802.2149502.4561602.6675102.8490302.97MT-363021901.5239201.7150701.8963902.0678702.2195402.33114102.41134902.46157903.974022801.6332401.8443302.0555802.2569802.4485502.61103102.75122602.85144202.435035602.2047102.4560102.6474702.9190903.11109003.29129103.116049802.9463003.2277803.5094303.75112603.80MT-403031901.5442701.8055002.0469002.2484802.41102502.52122302.57144402.54168804.474024301.7134802.0046802.2860302.5475702.7792902.95112103.07133403.1315703.295038302.4751402.7966103.0882703.34101103.56121603.71144403.876056303.3472103.6989704.01109304.27131004.45MT-503036501.6747501.9561302.2378202.4998802.73123302.94152403.11186303.23225505.024029101.9038402.2052102.5167702.8186803.09109603.34136603.56168303.74205103.815031402.4042802.7456803.0874003.4194703.72119404.00148604.25182604.756045603.2960703.6879004.06101104.41127404.74158305.68MT-643044002.1860102.5679402.92102303.25129203.52160503.73196603.86238003.89285106.584034702.4749602.8967403.3188503.69113204.04142004.34175304.56213604.70257105.575041003.1156903.5975704.0697804.50123704.90153705.23188305.50227906.376064604.3183704.86106205.37132505.84163106.25198307.32MT-803055202.9476003.34100503.75129104.14162304.51200304.85243805.14292905.39348208.444043903.2763203.7185804.15112104.59142505.01177405.41217205.78262306.10313205.265053204.1473304.6396705.12123805.62155006.09190606.54231106.96276906.446083805.77107006.34133806.90164807.44200107.96240407.76MT-1003073003.9696904.39125804.84160305.22201305.5024930
