January 9, 2012 - Jaga Climate Systems describes its new in-floor Micro canal radiator as a small and powerful heat exchanger that operates with quiet fans to ensure heating is virtually noiseless. At 6 inches high and 13 inches wide, the Micro Canal generates heat output while responding to changing temperatures. According to Jaga, the advanced trench-heating unit saves energy with its low-H2O technology, and is an ideal solution for when space is limited. JAGA CLIMATE SYSTEMS
January 4, 2012 - Equipped with expanded control logic, the Viessmann Vitodens 100 condensing space heating boiler can now deliver on-demand domestic hot water (DHW) with the new CombiPlus Kit. At a size of 9.8" x 17" x 8.7", the optional CombiPlus Kit can be mounted underneath or beside the boiler as part of a new boiler installation or as a later addition to the Vitodens 100. Generating up to 3.6 GPM of on-demand DHW, the kit eliminates the need for a DHW storage tank in some lower-load applications where space is at a minimum. Built-in temperature and flow sensors are included and DHW heating is managed through the boiler’s on-board control.VIESSMANN MANUFACTURING

December 16, 2011 - Guidance on increasing energy efficiency in existing buildings through measuring and tracking efficiency and implementing an efficiency plan is featured in the new book—Energy Efficiency Guide for Existing Commercial Buildings: Technical Implementation. The book recommends some tips on how to begin the energy savings process, such as: calculating energy use and cost; setting energy performance goals; measuring and analyzing current energy use; and tracking performance. It also features practical means and methods for planning, executing and monitoring an effective program, based on widely available techniques and technologies, adds ASHRAE.ASHRAE
December 9, 2011 - Jaga Climate Systems has unveiled its Clima Canal hybrid climate control system‚ a dual heating and cooling solution that fits seamlessly into spaces and provides energy-efficient and flexible temperature control, it says. According to Jaga, the Clima Canal offers extreme flexibility for architects and engineers looking for a powerful solutions that maximize space while using less energy. The Clima Canal system has a build-in depth of 10 cm, and can be topped with one of seven wood-grain or aluminum grilles to match the floor design, it addsJAGA CLIMATE SYSTEMS
November 21, 2011 - A new tool from Rockwell Automation allows manufacturers to calculate their potential savings from variable frequency drives to power pumps and fans through an online energy savings calculator. The free mobile app is compatible with iPad, iPhone, Blackberry or Android systems, and compares conventional methods, such as valves for pump control and dampers for fan control, to variable frequency drives and see estimated cost savings of installing an Allen-Bradley PowerFlex drive. The tool offers two ways to calculate energy consumption: users can enter the minimum pump or flow percentages, annual operating hours, cost per kilowatt and other information about their own factory; or use the sample data provided by Rockwell Automation built into the tool.ROCKWELL AUTOMATION
November 14, 2011 - ASHRAE has released the second edition “Procedures for Commercial Building Energy Audits” which it says promotes best practices, provides “how-to’s” and fills a void in available information for engineers, building owners, managers and government entities. The new publication includes time-saving tips for energy auditors, how to hire an auditor, what to ask for in a comprehensive audit report and how to build a successful energy efficiency retrofit team. Now available at the ASHRAE bookstore.ASHRAE
November 4, 2011 - Freeaire designs and manufactures commercial cooling and refrigeration systems that, it claims, harness cold, outdoor air to achieve up to an 50% increase in efficiency. The company's systems are designed to eliminate virtually all excess energy use in any particular cooling application by combining cool, outside air with a computerized control module that operates each conventional refrigeration system component independently. Freeaire says its systems achieve ROI in two to five years.FREEAIRE
November 4, 2011 - Otis claims its ReGen technology reduces energy consumption by up to 45% compared to traditional escalators, by feeding this energy back into the building's internal electrical grid where it can be used by other loads or users connected to the same network. According to the company, the amount of energy savings due to regeneration depends on various system parameters and configurations such as car load, speed, length of run, traffic pattern and system efficiency.OTIS ELEVATOR COMPANY
November 3, 2011 - Tate has expanded its product offering for the data centre market with ContainAire solutions, which include ContainAire Partitions, Strip, Hinged and Sliding Doors and Retracting Roofs. Containing an entire row of air has been shown to improve capacity and energy efficiency by reducing by-pass airflow and providing better control over supply and return air temperatures, says Tate, adding that its solutions are designed to increase cooling capacity by ensuring that all supply air is being funneled through the equipment. With the exception of the Retracting Roof, ContainAire solutions can be applied to cold and hot aisle containment configuration. TATE
November 2, 2011 - Mitsubishi Electric has introduced its new City Multi PWFY Hydronic Heat Exchanger, which functions in various modes to provide hot water up to 160ºF (approximately 71.1ºC), for applications such as commercial laundry services, industrial and residential kitchen spaces, or heating hotel pool water, it explains. The PWFY Hydronic Heat Exchanger unit is available in a 36,000 or 72,000 Btu/h capacities and operates in three modes – Heating (full temperature range), Heating ECO (supply temperature based on outdoor ambient) and Anti- freeze (maintains circulation to prevent pipe freeze), it says. According to the company, the unit is connectable to its VRF units, Water Source units and Hyper-Heating Inverter units, which will significantly increase the overall operating efficiency of the system when coupled with a heat recovery system.MITSUBISHI ELECTRIC
October 27, 2011 - Mitsubishi Electric has released the newest addition to its line of luxury controls, the PAR-30MAAU remote controller. The PAR-30 controller can control up to 16 indoor units in commercial applications and according to Mitsubishi, is the first controller from the company to offer a setback mode of operation that controls upper- and lower-limit temperature settings, preventing excessive temperature rise or fall. Other features include new styling, a backlit LCD screen, and a hold function that can be used to pause a previously scheduled operation.MITSUBISHI ELECTRIC
October 26, 2011 - Continental Fan says its TCD BC airfoil blower is a “precision-balanced” air-moving device featuring TEK backward-curved airfoil wheels. These impellers are manufactured of glass-reinforced polyamide; the company boasts they are stronger than a comparable steel wheel but at half the weight. The TCD BC blowers are combined with high-efficiency, single- or three-phase TEFC motors.CONTINENTAL FAN
October 26, 2011 – The Hyper-Heating (H2i) Inverter Y- Series PUHY units from Mitsubishi Electric claim to combine the ultimate in application flexibility with powerful cooling and heating capabilities to deliver precise comfort control to multiple zones in a building. The Y-Series uses a two-pipe system with a variety of indoor units and individual zone controllers, and can cool or heat up to 32 zones. By distributing capacity from one zone of a system to another, the Y-Series consumes only as much energy as each zone needs, making it an energy effective solution to total comfort control, explains the company.
