                                                                  已有626人浏览 添加时间:2019/6/12 7:47:15
                                                                   
                                                                  成都优成为大家介绍一下速冻设备如何选型:
                                                                  1、紧缩机容量应根据各蒸腾温度体系总机械负荷乘以工作时间系数断定。除特殊要求外,通常不设备用机。
                                                                  2、选用活塞往复式氟利昂紧缩机时,当紧缩比大于十应选用双级紧缩机;小于或等于十应选用单级紧缩。氟利昂双级紧缩体系通常宜选用一级节省中心不完全冷却方法。
                                                                  3、通常在冷库中一些的冷却器、油分离器、冷凝器、贮液器等设备均应与氟利昂制冷紧缩机的制冷才能相适应。
                                                                  4、选用氟利昂制冷紧缩机的工作条件,不得超越深圳冷库企业规则的限制工作条件。
                                                                  5、氟利昂冷藏制冷体系中,通常应选用回热循环。
                                                                  6、制冷紧缩机的工作时数,关于5~十0t的深圳冷库,通常可选用每昼夜工作12~16h。
                                                                   
                                                                   
                                                                   
                                                                   
                                                                  客服电话:400-8088-971       联系人:宫经理      客服QQ:463665578       Email:
