符合您的热负荷和过程需求的能力

制冷系统生命周期中最大的成本因素之一是能量。在许多制冷应用中，由于季节性变化，产品负载，占用率变化和导致功率损失的电器，容量超过了热负荷。现代专用的交流驱动器，例如Danfoss Drives的VLT®驱动器系列，提供了不断调整设备容量的理想手段，以满足实际的热负载和过程需求。收益大大降低能源消耗，运营和维护成本较低。

在任何优化的制冷系统中，智能压缩机和冷凝器/蒸发器风扇控制都是必不可少的。通常，您可以通过应用Danfoss AC驱动器来优化制冷压缩机，冷凝器和蒸发器的容量控制，从而节省10–25％的能源消耗。通过在平衡实际负载的能力的同时建立稳定性，系统范围的性能系数（COP）可改善提供大量节能的能力。

级联控制优化节能并降低生命周期成本
级联配置可在部分加载下的应用程序和AC驱动器之间产生最佳相互作用。基本负载由单个应用程序（例如由驱动器控制的压缩机）处理。当热负载升高时，驱动器一次启动其他压缩机。这样可以确保应用程序在其最佳效率点工作，并且驱动器在整个系统中保持最大的能效。

精心计划的级联控制还确保了各个应用的磨损最少。例如，通过旋转电源供电的压缩机，维护经理可以确保每个人都以相似数量的操作小时和相等的磨损水平结束。这增加了应用程序的寿命，并扩展了降低生命周期成本的服务间隔。

Danfoss Drives的高级多区域包装控制器可确保有效的级联和最多六个压缩机包。这可以最大程度地减少能耗，避免过于频繁的阶段和平整，稳定压力和温度，并减少压缩机磨损。同样，泵级联控制器在所有泵上均匀分布跑动时间，以使单个泵的磨损保持最低。

快速调试
使用Danfoss Drives显示面板，使用常见的制冷项而不是计算机语言非常容易。向导可以指导用户通过必要的设置。易于编程使安装人员和服务技术人员更加舒适和自信，使他们的工作更加轻松，更快，可以降低人类错误并提高员工的生产率。

商业制冷的热力学效率

商业制冷部门包括超市，大型超市和便利店等食品零售场所。它还包括数据中心中的精确空调。

典型的应用包括机架和包装，冷凝器，蒸发器和泵。

可靠性和热力学效率是任何商业制冷系统效率和有效性的关键因素。针对制冷应用量身定制的一系列功能可确保多功能兼容性，稳定性能，系统可靠性和最佳能源效率。

改善工业制冷的控制

工业制冷部门包括冷店和冷房间，肉类，海鲜以及其他食品和饮料加工单元，生物制药，化学和纺织厂。典型的应用包括工艺冷却器，冷凝器和蒸发器/空气处理设备和泵。

对于新鲜的水果和蔬菜，最初的冷却，加工和冷藏是食品工业中最能源密集型的过程之一。最初需要更快的冷藏速度来冷却新鲜的水果和蔬菜，以减慢它们的变质并保持收获前的新鲜度以及水果和蔬菜的风味。Danfoss AC驱动器在必要时提供快速冷却和冷冻。它们还保持均匀的温度，湿度，空气流通和新鲜空气供应，以使其在几个月内保持销售状况的冷藏，并且与常规装置相比消耗的电量少。

冷链中的温度控制物流

温度控制的物流对于确保食物，饮料和药物的保存和安全转移至消费者的保存和安全转移至关重要。典型的应用包括机架，包装，工艺冷却器，冷凝器和蒸发器/空气处理设备和泵。DANFOSS AC驱动器的可靠性和热力学效率可确保您的寒冷商店，食品加工厂，食品零售店以及整个冷链中的卫生环境。

冷却器

冷却器的可变速度控制使您可以提供最佳的过程温度，同时根据系统测量值将容量与实际需求匹配。当压缩机在部分负载下长时间运行时，速度控制是有益的。通过以较低的速度运行应用程序来降低运营成本，从而节省能源消耗。并通过优化系统和压缩机本身来降低安装成本。

Danfoss AC驱动器可确保较少的起点和停止，从而减少机械磨损。以及诸如石油返回管理，高压 /低压安全和跳过共振频率之类的专用功能可确保冷却器的安全操作。

betway88必威手机版压缩机的产品包括软启动器，高功率驱动器，带有内置级联控制器选项的AHF谐波过滤器，DC线圈和PID控制器。

启动和峰值负载策略

启动是压缩机操作的关键阶段。VLT制冷驱动器可最大程度地减少通过在操作过程中改变压缩机速度以调整能力的开始所需的开始数。在给定期间，最大的开始/停止循环可使用控制面板配置。

VLT制冷驱动器在短时间内提供了额定起始扭矩的135％。在正常运行期间，额定扭矩的110％可使用60秒。

为了延长驱动寿命，可以打开一个释放压力阀，以使压缩机能够在没有负载的情况下快速启动。

较小的压缩机具有相同的峰值负载

可以通过使用较小的压缩机配置系统来处理简短的峰值载荷，该系统的驱动器最高为90 Hz。这样，不一定需要较大的压缩机来应对峰值负载。

VLT制冷驱动器继续在可变速度压缩机失败的情况下控制固定速度压缩机。对于失败情况，中性区是由特殊的参数“固定速度中性区”设置的，该参数通过扩展中性区域的开头更少。

Danfoss和Anertech改变了数据中心冷却的未来

新解决方案可以扩展，而不会损害安全性，消耗更少的能源和水，并且比传统冷水机厂的成本少。
