A top Spanish hotel is cutting energy usage by 40% after equipping its heating, ventilation and air conditioning (HVAC) systems with ABB drives and high efficiency motors. Usage at the InterContinental Madrid has been reduced by 445,000 kWh a year.
The hotel has eight pump groups that serve its HVAC systems as well as hot water supply for guest rooms, kitchens and other facilities. Although these systems were well maintained and in good condition, the hotel management was concerned that the energy efficiency levels were below current best practice.
Ingersoll-Rand has announced its intention to acquire Thermocold Costruzioni, a privately-held Italian company that manufactures and distributes heating, ventilating and air-conditioning (HVAC) systems and solutions for residential, commercial and industrial buildings in Europe.
Dave Regnery, president, Commercial HVAC North America, Europe, Middle East and Africa, said: “This announcement is the next step in strengthening our portfolios to take advantage of the large market opportunity in Europe, and expanding distribution of Thermocold technologies to other parts of the world where demand is growing rapidly.”
One of Thermocold’s signature solutions includes the innovative multi-pipe HVAC system for high efficiency, simultaneous heating and cooling. This system recovers energy by shifting use from a separate boiler and chiller to one single, simplified multi-pipe unit that simultaneously delivers hot and chilled water. The system repurposes rejected energy, or uses renewable energy, for heating the facility delivering a more sustainable solution that reduces the amount of investment costs, use of floor space and total operating expenses. The multi-pipe system further contributes to lower the environmental footprint due to significant lower energy use.
Hans Güntner GmbH, which was the original name of the company, was founded in 1931 as a one-man business in a backyard in Munich. Today, the Güntner Group, which includes the sister companies Güntner GmbH & Co. KG, JAEGGI Hybridtechnologie AG and thermowave GmbH, boasts 9 production facilities on 4 continents and nearly 3,000 employees.
All aspects of the company's development have always been and continue to be shaped by internal driving forces: When Hans Güntner was unable to find any components for a facility that he was planning, he decided to build them himself.
Customers at the Steakhouse Amigo Ranch in Veendam, the Netherlands, enjoy their food in comfort thanks, in part, to a heat recovery system supplied by Mark Climate Technology.
The Mark Airstream CFX 6400 contains has an aluminium counterflow heat exchanger for recovering extracted heat, which is up to 90% efficient. The outdoor unit has an airflow of of 6400 m3/h. The restaurant has a 600m2 surface area and now gets ventilation without need for extra heating energy.
The kitchen now has three Mark extraction units whose air flow is 4000 m3/h.
German energy firm, SPIE, has won an award for its cooling technology, the company announced this week.
The award, presented by Germany's Minister for the Environment, Barbara Hendricks, was for its combined heat, power and cooling system for the pharmaceutical business Takeda in Singen. The SPIE system will save Takeda €1.1 million (~£854,000) net by using waste heat to power an absorption cooling system in the summer, and heating for the winter.
The hydroponics market (the method of growing plants in 'mineral nutrient solutions' instead of soil) is increasing demand for heating, ventilation and air conditioning (HVAC) systems, according to new research.
The forecast, by research firm RR Market Research, is for the global hydroponics market to reach US$ 395,2 million by 2020. The North American is growing fastest. Hydroponics provide better crop yields than traditional methods, and the method works well in areas with poor agricultural land climactic conditions.
To be successful with hydroponics, farmers need to control the environment closely, which is why demand for HVAC is growing in the market. LED lighting is used in the method too, the market for which is also developing.
