Hospitals are by their nature energy intensive, Aermec is helping to combat energy usage with an HVAC solution with the launch of its EHT active chilled beam, offering clean healthy air, acoustic comfort, reduced energy consumption whilst respecting the environment.
HVAC solutions in healthcare projects are required to meet more demanding than other buildings. Not only must they provide a safe and comfortable environment for patients and staff, but they must also address environmental criteria, be dependable, maintainable, and cost effective.
Active chilled beams can provide a constant air supply and allows for air paths to be tightly controlled whereas conventional air conditioning may involve air recycling and pressure changes. By using 100% outside air Aermec’s EHT can prevent recycling of air and provide individual temperature control in rooms.
Aermec’s next generation EHT hybrid induction terminal combines, cooling, heating, fresh air, ventilation-only and air distribution in one compact device for rooms with a ceiling height of up to four metres.
With a need to focus on moving towards the government’s net zero targets, the EHT offers a solution that delivers high performance but with limited energy consumption.
“The EHT active chilled beams offer an attractive HVAC solution for hospital environments by offering good air quality and acoustic comfort with reductions in energy consumption. The EHT can help NHS hospitals by reducing their carbon footprint and reach their net zero goal in 2045,” says Michele Gioachin, Aermec’s Export Sales Manager Aermec S.p.A and President of Aermec UK.
A fundamental feature of the EHT is its aesthetic appeal making it an ideal solution for a diversity of interiors, including offices, hotel rooms, airports, railway stations, hospital environments and any large area in general.
The innovative design of the EHT’s nozzles sets it apart. Developed using CFD analyses, their moulded production quality that guarantees an induction ratio up to six, (independent testing was conducted by the University of Aachen in Belgium). With no moving parts the EHT offers unprecedented acoustic comfort.
Environmental consideration was a key part of the design process. Parallel heat exchangers maximise efficiencies and the unit fully exploits the Coanda effect. Consideration was given to the optimisation of the finned coils, obtaining the maximum heat exchange coefficient with reduced pressure drops on the air and water side, resulting in the highest levels of comfort whilst respecting the ecosystem.
Clean air
Any dehumidification is addressed by the air handling unit, resulting in no condensate inside the EHT beam, eliminating the risk of mould and bacteria and other organisms that may be harmful to health.
Design flexibility
Air of the highest quality is injected into the space – the air handling unit filters, treats and dehumidifies fresh air before sending it into the EHT. The option to be able to select the right configuration of the nozzles, ensures that the right fresh air flow rate can be guaranteed for the required application.
Installation
Installation is quick and simple and for ease of maintenance components are accessed from below, by opening the suction grille. Architectural integration ensures compatibility with 600x600mm false ceiling tiles and the head-to-head positioning of two adjacent units results in a seamless visual effect. The EHT is suitable for new and refurbished buildings.
Benefits
Excellent air quality
High acoustic comfort
High performance nozzles
Maximum energy savings
Optimum accessibility
Chilled beam technologies can reduce initial investment costs as well as operating costs compared to more conventional HVAC systems. In addition to their efficiency and always providing the right temperature, the units provide a discreet aesthetic HVAC solution.
