Danfoss provides AC-drive solutions for fire and smoke safety, heat dissipation, harmonic mitigation, and EMC and seismic compliance. In hospitals, failure for any reason can jeopardize lives.
Drives powering pumps and chillers must be extremely reliable and virtually immune to mains supply disruptions. To achieve this reliability, Danfoss AC drives are designed to ignore voltage sags and even short outages, maintaining full performance at all times.
While AC drives increase precision, save energy and extend application lifetime, they also introduce harmonic currents to the hospital grid. If not kept under control, harmonic currents can affect the performance and reliability of generators and other equipment. To ensure minimal disturbance, read more about our harmonics application know how, software tools and harmonic mitigation solutions.
Metro and motorway tunnel operators demand strict ventilation performance for safe operation and optimized cost of ownership. All our units offer the same HVAC-dedicated functionalities, standards compliance and compatible soft starters, filter and fieldbus communications options. With hundreds of thousands or even millions of passengers annually, ventilation is a top priority for international airports.
To improve traveler comfort and safety, and to combat rising electricity prices, drives are increasingly being used to control and optimize the operation of air-handling units and reduce energy consumption. And the complete range of fieldbus communications options enables effective integration with the building automation system. When building an HVAC system, to get the highest performance and system efficiency, the individual components — motor, drive and fan — need to be flexible and broadly compatible with each other.
For instance, if you specify a high-efficiency motor that is only compatible with lower efficiency fans, the overall system efficiency would suffer and would not reflect the high performance — and investment — in the individual components. Deploying the best environmental and energy technology, the hotel comes close to achieving carbon neutrality.
This tough and savvy FC drive enhances pump and fan applications in building management systems, and runs outdoors in most climates. FC is dedicated to controlling compressors, pumps and fans for significant energy savings in refrigeration plants.

Electric motors are normally hidden from sight, but they are used by many types of equipment. In all types of buildings, plumbing and mechanical systems are strongly dependent on motors. They can be found in pumps, fans, air conditioning compressors and chillers, to name a few examples. Building owners can reduce power bills significantly by improving motor efficiency. There are two main ways to achieve this, which can be combined for better results:. An adequate power supply is fundamental for electric motors. If a motor is exposed to frequent voltage fluctuations, its service life is reduced dramatically. Before upgrading your motors and adding speed controls, check if your power supply has a stable voltage and frequency. When upgrading the motors in a building, the best recommendation is looking for units with recognized efficiency ratings.

Learning objectives:. Since the invention of the battery in and development of dc motors a few decades later, the simple electric motor has evolved into a sophisticated electrical device with electronic control options. The development of motors first focused on the dc type, as batteries were the primary electrical source at the time. Motor development evolved to the use of induction, synchronous, and other alternating current forms. The use of motors and specification options has developed at an ever-increasing pace, as regulatory requirements and efficiency needs have forced the simple electric motor to use less energy and become smarter.
Unfortunately, around this time of year, many homeowners are already experiencing AC failure. One of the most common issues our technicians see is a broken fan motor. Its job is to cool the superheated refrigerant that moves through the condenser coils of your AC unit, which helps to cool your home. The surest way to prevent a broken fan motor or any other kind of air conditioning breakdown is with routine maintenance.

AC electric motors used on fans typically consist of windings, bearings, and other internal mechanical parts. All those parts need to be enclosed by what's referred to as a frame, which serves a dual purpose. The frame protects the internal parts, but at the same time, it allows heat generated within the windings to be dissipated from the motor. Some motor frames also have external fins that are used to help dissipate the heat.
They are used in HVAC equipment that are installed in residential as well as commercial buildings. Furthermore, AC motors are also used in a variety of equipment, such as household appliances, and industrial equipment such as fixed cranes and conveyor belts. The market is expected to witness significant growth, which is attributed to the augmented modernization and automation of industrial processes. These products are cost-effective as they incur negligible maintenance cost due to their construction. They do not comprise accessories such as slip rings, brushes, or commutators, which require maintenance.
Driving motor efficiency
For more than 20 years, VFDs have successfully been installed on fan and pump motors in a range of variable load applications. Energy savings vary from 35 to 50 percent over conventional constant speed applications, resulting in a return on investment of six months to two years. While the number of applications suitable for early generation drives was limited based on the horsepower of the motor, today's drives can be installed in practically any HVAC application found in commercial and institutional buildings. Systems can be operated at higher voltages than those used by earlier generations, resulting in off the shelf systems for motors up to horsepower. Early generation systems also suffered from low power factor. Low power factor robs the facility of electrical distribution capacity and can result in cost penalties imposed by electrical utility companies.
Ac Damper System. For example, an HVAC damper might close in the ducts that lead downstairs in order to more effectively cool the upstairs. Effective because unit captures pollutants at the source bathrooms, kitchen, laundry room and distributes fresh air to living areas bedrooms, living room. Therefore, if the appliance is in an unheated space, there is no benefit to a vent damper.

Energy-efficient motors are used in various industries like commercial building, residential, and agriculture. The higher performance of these energy efficient motor coupled with low protection prices has resulted in fuelling their demand for numerous applications. The rising cost of electricity is a major problem worldwide. The electricity consumption can be made efficient either by making the motor extra efficient or controlling the velocity at which they run.
Пока люди переговаривались, оба светляка направились к зеленому куполу, оставив Ричарда и Николь почти во тьме. Они извлекли фонари из рюкзаков. - Что-то мне подсказывает - близится конец нашего путешествия, - промолвил Ричард и двинулся в сторону Изумрудного города.
Ворота они увидели через бинокль с расстояния около километра. Ричард и Николь весьма взволновались.
Едва мы адаптировались к определенному набору условий жизни, их резко меняли. И я не сомневаюсь, что смерти Даррена можно было избежать, не будь все в том подземном мире настолько странным. В другой раз мы едва не потеряли Катю, когда ей было всего два года.
какая-то морская каракатица приняла ее любопытство за акт агрессии. - А когда нас второй раз отправили спать, - проговорила Симона, - и переместили в этот Узел, мы с Майклом были утомлены и обессилены после многих лет опытов. Дети выросли, завели собственные семьи, и мы потребовали уединения, которое нам и предоставили.
Однако в нескольких метрах от выхода наверху маячила парочка часовых. К счастью, их внимание было настолько поглощено фейерверком в раманском небе, что они не услышали, как трое мужчин выскользнули наружу по лестнице. Потом в целях безопасности троица разделилась: каждый из них направился в логово октопауков собственным путем.
