New possibilities for commercial HVAC and building automation

Commercial Air Conditioning

Panasonic and Schneider Electric are working together to facilitate energy management. The synergy of commercial air conditioning systems with building automation components should enhance building efficiency and reduce operating costs.

Panasonic Corporation, a global leader in the development of a wide range of electronic technologies and solutions, and Schneider Electric, an international specialist in energy management and automation, have disclosed a synergic commercial air conditioning and construction solution at Chillventa, a fair in Germany. Possibilities for the control of heating and cooling systems technologies, can make modern buildings more energy-efficient. The partnership is based on the expertise and market leadership of the two companies in the areas of commercial air conditioning engineering and building automation.

Together, the companies have developed a new, wireless interface solution that enables serial communication of the Schneider Electronics automation systems and room controllers with the Panasonic VRF air conditioning systems.

Through this integration, real estate owners have a clear overview of central building systems such as climate technology, lighting, security, energy and power supply, on a single screen at any time. On the basis of these data the systems can be optimized and thus the energy consumption can be reduced.

Recently Panasonic has massively invested in development of commercial air conditioning systems and support services to answer the market’s needs, and now anticipates to be able to propose to the customers operating expenses reduction by combining the benefits of building management with the most innovative VRF technology.

Energy costs can be reduced thanks to interconnection between commercial air conditioning and building control systems. Regardless of the type, size and age of the building Panasonic/Schneider Electric can offer a complete building management system. This strong digital support significantly increases the transparency of the building environment.

VRF climate systems are growing more and more wide-spread in commercial buildings. Their feature of adapting their output to the actual demand is very beneficial as thus significantly less energy is consumed. Panasonic’s VRF system (ECOi / FSV) has been optimized for energy efficiency. The system is extremely reliable and it still heats or cools reliably even at extreme outside temperatures of -25 ° C to 52 ° C °.

Schneider Electric’s SmartStruxure ™ system maximizes building efficiency. In addition, operating costs are reduced throughout the entire life cycle of an installation by integrating specially adapted hardware, software and systems and service offerings into a system. This allows buildings to be professionally managed and operated with energy efficiency. Individual “information islands” are also integrated into the system so that real-time insights are created that enable the facility manager to make more intelligent decisions to optimize energy management.

The joint commercial air conditioning solution from Panasonic and Schneider Electric is available worldwide, with the exception of the Japanese market.

Heating Cooling Systems: new design and improved performance

Heating Cooling Systems

Design of commercial HVAC (heating cooling systems) systems serves not only aesthetic purposes but becomes a model for the improvement of past technologies. The design of the new Samsung heating cooling system HVAC 360 follows a 360 degree spherical model that allows to convey air without the use of lamellar system for the direction of flow, integrating, in particular, a Booster Fan that uses pressure to generate a 360-degree spatial airflow.

The room temperature is constantly monitored to ensure maximum comfort, providing homogeneous air distribution inside the room, with an increase of the area of coverage by 39% compared to a conventional air conditioning model. The conventional cassettes are therefore replaced by this innovative model that can provide 100% of the incoming air volume without loss.

Samsung HVAC 360 guaranties a conjoint operation with the exterior unit. Besides, the efficiency of an inverter system and its compactness make it perfectly match the idea of an eco-friendly product. Especially compared to conventional heating cooling systems that cannot rely as HVAC 360 on a speed-variable compression system. Saving energy, in this case, is remarkable, considering that, independently, the machine will turn off reaching the ideal preset temperature.

Samsung DVM S is the first air conditioning system capable of achieving a 30HP (84 kW) of peak power per unit, including a new Super Inverter Scroll Compressor with flash injection technology, which improves performance by 21% compared to conventional heating cooling systems.

The developers have spent four years to complete a heating cooling system that integrates the principles of eco-sustainability and energy efficiency. The size, in this case, has been reduced to a minimum, by providing a simultaneous reduction in the number of compressors (from three units to two units) and an improvement of the thermal management achieved by separating the heat exchanger pins. What is the result? It weighs 29% less and 40% less space is required for its installation.

In addition, the Samsung DVM Chiller combines an air-cooled chiller with variable refrigerant flow (VRF) in a compact unit that can significantly reduce the required size of the installation area. Furthermore, the models can be combined in various ways to extend the capacity up to 320 tons.

Samsung DVM S ECO, finally, is a new type of side discharge designed to provide a unique solution for apartments and offices. The design was equipped with an Inverter Scroll Compressor that is considered to improve heating by 20%, and besides the air flow by at least 10% compared to standard side discharge VRF units.

Samsung HVACB Division is focusing a lot on the engineering of components. Samsung strives to meet their customers’ expectations both in residential and commercial heating cooling system to ensure energy savings and offer products that would provide the maximum in respect of eco-sustainability and reduction of necessary installation space.

Data centers air conditioning – Commercial HVAC

Commercial HVAC

Data centers all around the world generate massive amounts of heat in course of data management and processing and demand a proper commercial HVAC in order to avoid over-heating. Nowadays data centers are essential for an array of different business, who simply cannot do without. And the demand for IT performance is constantly growing. Trends such as cloud technologies and big data computing, as well as the increasing use of multimedia services by private households, have led to a significant increase in the number of servers, storage and network infrastructures in the data centers in recent years. Thus the power consumption in data centers has boosted as well. Additionally, the energy prices are increasing considerably, thus data centers demand from businesses more and more investments in commercial HVAC. The days when energy costs compared to other IT costs were insignificant are over.

Data centers are usually planned individually because they have particular tasks to fulfill. It’s extremely important already in the planning phase, to coordinate the air conditioning with the data center concept because the right commercial HVAC guarantees maximum failure safety with the lowest operating costs.

Over the past few years, operating costs have shown that the use of conventional recirculating air conditioning systems with CRAC / CRAH units are no longer economically viable. Commercial HVAC systems working by means of untreated outside air, can only be used to a limited extent. A modern and energy-efficient solution is air conditioning equipment that can be adapted to the climatic conditions in data centers. Energy-efficient flexible systems that combine in themselves free cooling, evaporative cooling and mechanical cooling. The use of outdoor air by free cooling is advantageous with regard to energy savings. One differentiates the direct and indirect free cooling. With direct free cooling, outside air reaches the IT room directly. Moderate climatic zones, are therefore perfect locations for equipment with this commercial HVAC system. The cooling is carried out in several steps depending on the external and the processed air.

At low outdoor temperatures, cost-efficient free cooling is achieved by the use of EC fans. The evaporative cooling is switched on from a certain outside temperature. The adiabatic cooling is based on the physical principle that when water evaporates and changes its aggregate state, water abstracts the required energy from the environment. By supplying moisture, an air stream can thus be cooled. In the case of indirect adiabatic cooling in the recirculating-air principle, the external air is humidified to a maximum and cools the exhaust air via one or more heat exchangers. The outside air absorbs the waste heat and releases it together with the moisture as an air to the environment. Compared to conventional air treatment, commercial air conditioning via free and indirect free cooling can make a great contribution to the saving of energy for commercial HVAC in data centers.
