is a powerful platform to use for various calculations concerning Air filters and IAQ. The CFSS contains software applications such as: The CFSS contains several software applications that can be used for calculating the Life Cycle cost for air filter applications. Life time, energy consumption and the total operating cost of the filter installation is calculated. Additional information such as CO2 emissions and efficiency of the filter system is also provided. You may compare up to three different filter installations instantly and compare the results in a new graphical interface. You may also simulate a real filter installation by using various filter sizes in the filter housing. With the special LCC POWER application you may analyze the best filtration solution for power generating gas turbines. Read more about LCC - Energy saving software The CREO software is essentially a marriage of Camfil’s well known and frequently used LCC (Life Cycle Cost) Green software along with its clean room design software.

The two software programs combine to make a robust planning tool that identifies the best air filter options to optimize clean room filtration and energy consumption. Taking into account the latest international industry norms, the tool also generates complete filter and hardware specifications in a simple, easy-to-use format. The software is ideally suited for A&E companies and end users who operate clean rooms in order to optimize their air filtration needs. Read more about CREO Software The HPE gives you the ability to get real efficiencies, pressure drops and construction data for various HEPA and ULPA filters manufactured by Camfil. You may compare up to three different solutions in the new report structure. You may use the software to find the best solutions based on filter sizes and efficiency requirements. This unique software application can help the designer of a clean room to estimate the cleanliness class in clean rooms or in other spaces (offices, etc.) using Camfil filters.

Depending on the number of people, the activity in the room, the ventilation system and the filter selection the clean room class is calculated. home ac repair baton rougeThis is a very quick and accurate tool for the clean room designer to make the first estimation on what filter selection is needed. mitsubishi ac units troubleshootingComparison up to three different solutions can be obtained with just a few inputs. 1.5 ton air conditioner price in bangladeshWith the CAT you can get efficiency, classification data, pressure drop information for the real operating airflow. This software is currently using the EN779 test data on many of Camfil comfort filters. This easy to use application is a very helpful tool to service users with basic filter performance information.

The Camfil chemical/carbon selection program is designed to help users and design engineers to estimate lifetime and efficiency of chemical/carbon filters against specific target gases at given concentrations. The software programs clearly demonstrate Camfil’s continuing commitment to serving our customers and optimizing filter selection for the microelectronics industry.

April 2014, Volume 7, Issue 2, pp 335–351Review of automated fault detection and diagnostic tools in air handling unitsReview ArticleFirst Online: 21 November 2013Received: 30 July 2013Accepted: 31 October 2013DOI: 10.1007/s12053-013-9238-2Cite this article as: Bruton, K., Raftery, P., Kennedy, B. et al. Energy Efficiency (2014) 7: 335. AbstractStudies have indicated that 20–30 % HVAC system energy savings are achievable by recommissioning air handling units (AHU) to rectify faulty operation.

Studies have also demonstrated that on-going commissioning of building systems for optimum efficiency can yield savings of an average of over 20 % of total energy cost. Automated fault detection and diagnosis (AFDD) is a process concerned with automating the detection of faults and their causes in physical systems. AFDD can be used to assist the commissioning process at multiple stages. This article presents a review of the research work that has been carried out on the use of AFDD tools in improving the efficiency of AHUs. This updates and expands upon the most recent literature review in this area, published in 2005. The article offers a comparative analysis of the FDD techniques currently in use and offers an opinion as to which show most potential for widespread adoption as part of the on-going commissioning process. It then details the issues which have impeded the adoption of existing AFDD tools for AHUs to date before concluding with an appraisal of current and recommended areas for future research to overcome the barriers to the widespread adoption of AFDD tools in AHUs.KeywordsCopyright information

At full 100% throughput, AirMaster heat recovery ventilation units emit only 35 dB(A) at 1m. Where noise limitation is crucial, a further reduction can be obtained by setting air flow to 80% of full throughput, resulting in only 30 dB(A) at 1m.EC (electronic commutation) drive motors enable the air handling unit fans to modulate between 40% and 100% of full throughput. This means that air delivery is always closely aligned to room requirements, so that the power consumption profile is consistently as low as possible. It is not necessary to have defined speed settings, such as trickle or boost.AirMaster heat recovery ventilation units placed against the walls of a room to be served have negligible air pressure loss. Units can also be used away from walls, with ducting of up to around 10m length. In these cases, the fan drive motor is delivered with a higher setting, so that the fan can overcome duct pressure loss and still manage the required air volume. Although noise emission for these units is higher, the duct muffling effect largely neutralises this increase and holds emitted noise to the same duct-free 30 and 35 dB(A) levels.

AirMaster air handling units with only 30 dB(A) noise emission are a godsend to designers tasked with finding ventilation solutions for projects such as Special Educational Needs (SEN) schools, clinics and community centres with quiet areas.Even with the bypass damper fully open, AirMaster heat recovery ventilation units are able to reduce noise by approximately 49 dB. When placed next to classroom windows exposed to traffic noise around 60 dB(A), the muffling effect of direct ventilation units reduces the resultant noise ingress to 7 dB(A). This is so low as to be negligible.AirMaster air handling units can provide a constant supply of fresh air without the noise ingress and pollution which result from open windows. Natural ventilation, such as opening windows, can be inexpensive to begin with. However, it is hugely energy inefficient , can cause draughts, is uncomfortable in winter and impractical on days with high winds or rain.Where the level of environmental noise is known (typically from a field survey), SAV Systems can provide a spreadsheet to establish the net impact of such noise after passing through an AirMaster unit.
