Product DescriptionEco - Healthcare is one of Frenger’s latest range of high performance Chilled Beams. Energy efficiency has been a key driver for such advancements in Frenger’s Chilled Beam Technology.

Eco - Healthcare is 227mm deep as standard and can be increased to 267mm deep for higher air volumes. Eco - Healthcare can achieve 1016 watts per meter total cooling (based on 10∆tk and 25 ltrs / sec / m for a beam supplied at 16°C with a 100Pa).

The Eco - Healthcare beam contains a number of Frenger’s Patent pending performance enhancing features and as can be expected from the Frenger brand, the Eco - Healthcare beam is also designed to be easily tailored to suit the unique parameters of individual project sites, for the optimum product / system efficiencies. This is partly achieved by Frenger’s “burst nozzle” arrangement that not only encourages induction, but also reduces noise. Given the size and amount of burst nozzles being appropriately quantified for each project, this provides consistent jet velocities, equal distribution of the air discharge and continuous induction through the entire length of the heat exchanger (battery). There are no dead spots due to plugging back nozzles from a standard pitch or having to adjust the pressure in the system to suit the amount of open standard nozzle sizes as associated with many competitors’ active beams as dead spots and / or reduced jet velocities decrease their cooling capacities / efficiences.

Frenger’s heat exchanger batteries are also fitted with extruded aluminium profiles to not only enhance performance but also provide a continuous clip on facility for the underplates. This arrangement keeps the underplates true and flat for long lengths, even up to 3.6m.

Eco - Healthcare is designed with hospital / healthcare environments in mind. The fin coil battery element can easily be lowered to allow cleaning of all four sides. Eco - Healthcare units are finished in RAL 9010 (20% Gloss) White as standard.

Eco - Healthcare is available in any length from 1.2m up to 3.6m in 0.1m increments and is constructed from zinc coated mild steel for its outer casing rather than extruded aluminium which is utilised for Frenger’s other products. This is the area where the value engineering has occured. The cooling and heating internal components are the same high quality construction for Eco - Healthcare™ as utilised for Compact™ and Ultima™ and as such similar cooling / heating performance.

The air chamber for Eco - Healthcare is the largest in Frenger’s product range and can accomodate up to 90 ltrs / sec with its 160mm diameter single air inlet connection point.

Eco - Healthcare beams all have a “closed back”, thus meaning that all induced air (recirculated room air) is induced through the underplate within the room space to avoid and need for perimeter flash gaps and / or openings in the ceiling system. This also provides for a better quality for recirculated air as the recirculated air does not mix with any air from the ceiling void. The indcution ratio of Eco - Healthcare is typically 5 times that of the supply air (fresh air) rate.

In addition to Eco - Healthcare’s high cooling performance capability of in excess of 1000 watts pre meter, Eco - Healthcare can operate well and induce at low air volumes, as little as 3 l / s / m and even with a low static pressure of just 40Pa. Likewise Eco - Healthcare can handle air volumes up to 30 l / s / m and up to 120Pa. Please note however that there high air volumes should be avoided wherever possible and are the absolute maximum and hsould not ever be exceeded. As a “rule of thumb” 25 ltrs/sec/m from a 2 way discharge beam is the maximum for occupancy comfort compliance to BS EN 7730.

Eco - Healthcare can have integrated heating with seperate connections (2 pipe connection for cooling and 2 pipes for heating).

The maximum total supply air for the product is limited to 90 ltrs/sec, which equates to 25 ltrs/sec/m for a 3.6m long beam.

Drop down heat exchange battery for easy cleaning to all four sides of the heat exchanger.

High output “1016 W / m”. Can accommodate up to 90 ltrs / sec. Optimise discharge nozzle size and pitch factory set to

best suit project requirements. Coanda effect is initiated within the beam. Discharge veins are concealed within the beam for

improved aesthetics. Fan shape distribution for increased occupancy

comfort. Unique fast fixing of removable underplates that

prevents any sagging eben on long beam lengths of 3.6m.

Various different perforation patterns available for removable underplates.

Multiple manifold variants to enable reduced chilled (and LTHW, if applicable) water mass flow rates to be facilitated for increased energy efficiencies.

Operates well at “Low Pressure” and “Low Air Volume” for increased energy efficiencies.

Provides indoor climate in accoradance with BS EN ISO 7730.

HygieneIt is important to clean the product to ensure that it looks its best, that it operates at an optimum level, that it will last as long as possible and that it does not present an infection control risk. During development of the Frenger Eco - Healthcare chilled beam the ease of cleaning was of the highest priority.

The underplate to Eco - Healthcare is simple to lower or totally remove. The underplate hooks onto a patent pending extruded aluminium section which is part of the fin coil battery. When “joggled” off the extrusion the underplate can hang on the factory fitted safety cords.

When the underplate is either hanging down on the safety cords or totally removed, the fin coil battery is accessible from below. The fin coil battery can be easily lowered by the removal of four retaining screws (pozi headed screwdriver) to enable 60mm clearance behind the fin coil battery and ample clearance to both sides where air passes.

Air Cooling EffectCooling effect supplied in the ventilation air [W]

1. Start by calculating the requried cooling effect tat has to be supplied to the room in order to provide a certain tem-perature.

2. Calculate any cooling effect that is provided by the ventila-tion air.

3. The remaining cooling effect has to be supplied by the beam.

Formula for air cooling effect: P = m x Cp x ∆tWhere:m = mass flow [kg/s]Cp = specific heat capacity [J(kg-K]qp = air flow [l/s]∆t = the difference between the temperature of the room and the temperature of the supply air [K]

It is usually m x Cp ≈ qp x 1.2

Air cooling effect as a function of airflow. For example, if the air flow is 30 l/s and the under-temperature of the supply air is ∆tra= 8K, the cooling effect from the graph is 290W.

Notes:1) Performance calculations are based upon normal clean potable water; it is the system engineer’s responsibility to allow for any reduction in cooling or heating performance due to additives that may reduce the water systems heat transfer coefficent.

2) Pressure drop calculations are based upon CIBSE guides using clean potable water and exclude any additional looses associated with entry / exit losses, pipe fouling or changes in water quality; it is the system engineer’s responsibility to use good engineering practice.

Calculation Program

Frenger’s calculation programme for Eco - Healthcare is extremely user friendly.

Simply select from the drop down menu the “Air Connection” configuration. Air volumes in excess of 40 ltrs/sec and up to 50 ltrs/sec should be 2 x 80 diameter.

“Manifold Types” can be changed in the drop down menu for increased waterside cooling effect, however attention needs to be taken regarding resultant pressure drops (hydraulic resistance), If pressure drops need reducing, choose a higher numbered manifold (C5 being the highest and C2 being the lowest).

“Discharge Throw” can be S (short), M (medium) or L (long).

“Underplate Perforated” options can be found on page 13.

Complete your project data in the “Design Conditions” section. Please note that the “Air On” Thermal Gradient should not be used in normal instances.

“Performance Data” will then automatically be calculated. Like-wise “Dimensional Date” will be also automatically calculated.

Finally, the “Design Check” should read “OK” in green, or detail some warning in red.Calculation programmes for Eco - Healthcare are available upon request.

Project Specific Testing FacilityThe 3 number state-of-the-art Climatic Testing Laboratories at Frenger’s Derby based technical centre, have internal dimensions of 6.3 x 5.7 x 3.3m high and includes a thermal wall so that both core and perimeter zones can be modelled. The test facilities are fixed in overall size and construction therefore simulation of a buildings specific thermall mass cannot be completed, it should, however be noted that a specific project can be simulated more accurately by recessing the floor and reducing the height as necessary.

Project Specific Testing

Project specific mock-up testing is a valuable tool which allows the Client to fully asses the proposed system and determine the resulting indoor quality and comfort conditions; the physical modeling is achieved by installing a full scale representation of a building zone complete with internal & external heat gains (Lighting, Small Power, Occupancy & Solar Gains).

The installed mock-up enables the client to verify the following:

Product performance under project specific conditions. Spatial air temperature distribution. Spatial air velocities. Experience thermal comfort. Project specific aesthetics. Experience lighting levels (where relevant). Investigate the specific design and allow the system to be

enhanced.

The project-specific installation and test is noramlly conducted to verify:

Product capacity under design conditions. Comfort levels -air temperature distribution

-thermal stratification -draft risk -radiant temperature analysis

Photometric Testing FacilityThe photometric test laboratories at Frenger Systems are used to evaluate the performance of luminaires. To measure the performance, it is necessary to obtain values of light intensity distribution from the luminaire. These light intensity distibutions are used to mathematically model the lighting distribution envelope of a particular luminaire. This distribution along with the luminaires efficacy allows for the generation of a digital distribution that is the basis of the usual industry standard electronic file format. In order to assess the efficacy of the luminaire it is a requirement to compare the performance of the luminaire against either a calibrated light source for absolute output or against the “bare” light source for a relative performance ratio.

The industry uses both methods. Generally absolute lumen outputs are used for solid state lighting sources and relative lighting output ratios (LOR) are used for the more traditional sources. Where the LOR method is chosen then published lamp manufacturer’s data is used to calculate actual lighting levels in a scheme.

The intensity distribution is obtained by the use of a Goniophotometer to measure the intesity of light emmitted from the surfaceof the fitting at pre-determined angles. The light intensity is measured using either a photometer with a corrective spectral response filter to match the CIE standard observer curves or our spectrometer for LED sources.

Luminaire ouputs are measured using our integrating sphere from smalled luminaires or our large integrator room for large fittings and Multi Service Chilled Beams. For both methods we can use traceable calibrated radiant flux standards for absolute comparisons.

All tests use appropriate equipment to measure and control the characteristics of the luminaire and include air temperature measurements, luminaire supply voltage, luminaire current and power. Thermal characteristics of luminaire components can be recorded during the testing process as required.

A full rest report is compiled and supplied in “locked” PDF format. Data is collected and correlated using applicable software and is presented electronically to suit, usually in Eulumdat, CIBSE TM14 or IESN standard file format.

Frenger conduct photometric test in accordance with CIE 127:2007 and BS EN 13032-1 and sound engineering practice as applicable. During the course of these tests suitable temperature measurements of parts of LED’s can be recorded. These recorded and plotted temperature distributions can be used to provide feedback and help optimise the light output of solid state light source based on luminaires which are often found to be sensitive to junction temperatures.

Acoustic Testing FacilityThe Acoustic Test Room at Frenger is a hemi-anechoic chamber which utilises sound absorbing acoustic foam material in the shape of wedges to provide an echo free zone for acoustic measurements; the height of the acoustic foam wedges has a direct relationship with the maximum absorption frequency, hence Frenger has the wedges specifically designed to optimise the sound absorption at the peak frequency normally found with our active chilled beam products.

The use of acoustic absorbing material within the test room provides the simulation of a quiet open space without “reflections” which helps to ensure sound measurements from the sound source are accurate, in addition the acoustic material also helps reduce external noise entering the test room meaning that relatively low levels of sound can be accurately measured.

The acoustic facilities allow Frenger to provide express in-house sound evaluation so that all products, even project specific designs can be assessed and optimised.

To ensure accuracy Frenger only uses Class 1 measurements equipment which allows sound level measurements to be taken at 11 different ⅓ octave bands between 16 Hz to 16 kHz, with A, C and Z (un-weighted) simultaneous weightings.

In addition to the above, Frenger also send their new products for specialist third party Acoustic Testing. The results of which are very close and within measurement tolerances to that of Frenger’s in-house measurement of sound.
