Dusan adds , “ this function is also‐ very useful between suppliers delivering directly to site and the contractor . By assigning a claim number on deliveries or part-deliveries , it is easy to identify duplicate orders - such as piping for example . So , as a contractor on site , if you have already received your 20 lengths of piping and it is marked off on the Revit model as ‘ delivered ’ – when another load of the same 20 lengths is requested by site personel , you know there is a problem . The same applies for other HVAC systems components like dampers , flexies , bends , refrigerant piping , insulation , and so on .”
This solution is also highly beneficial to sites in remote locations where getting stock items delivered to site again is difficult , or very costly . With the guarantee of an extremely accurate item-count done by software , the risk of under or over supply is by far reduced , thus ensuring a more accurate project costing and claiming process too .
As par of this solution , a costing can also be added to each item , thus providing a comprehensive BoQ and accurate pricing estimate – all of which saves a lot of time throughout the supply chain and for site management . For example , ducting square or spiral sections can be costed per square meter or per weight , depending on the client ’ s preference .
As part of this process Dusan also notes that many objects and families related to HVACR have been developed by taking base information from local suppliers and applying ODA ’ s specialist knowledge . Stefanov himself is a 35-year industry roleplayer who has also worked on three different continents around the globe .
“ The reason this solution has not existed until now is for a number of reasons . Not only is it expensive for the setup costs and equipment required to do this type of modelling and reporting but also because people don ’ t have the time to invest in such work that is required in customising a product . We have taken that step and now have the advantage of the rewards for what has been put in , and as a full design solution this can be applied to any project designed within the software ”, Dusan concludes .
Note : Revit is an Intelligent 3D model-based design set of tools that supports a modelling workflow , where deliverables such as drawings and schedules come directly from a single , unified model . Changes are automatically reflected in all views and BoQ schedules of the model , and adjacent / connected elements automatically update to maintain established relationships . The Revit software is a powerful product that can create 2-dimensional and 3-dimensional designs , snippets , and even facility walkthroughs .
For demonstration of the power of the BoQ derived from Revit MEP model , ODA Design & Drafting will be available to address any queries and provide more information on this cutting edge solution . RACA
Danfoss scroll compressors : next-generation systems meeting the challenges of complex applications , increased energy efficiency and varied climates
Driven by the global need to reduce CO 2 emissions , new legislations around the world are demanding air conditioning systems with higher energy performance as well as non-ozone depletion potential ( non-ODP ) and lower global warming potential ( lower-GWP ) refrigerants .
These legislations affect all unit types and have led to the re-design of a large number of HVAC ranges . As well as conforming to strict new standards , next-generation systems need to meet the challenges of complex applications , increased energy efficiency and varied climates , while also providing flexibility and top comfort .
As a result , the HVACR industry is facing increasing complexity and multiple challenges in terms of development , running and maintenance costs .
Reducing costs across the entire product lifespan in the application
Danfoss Universal Scroll Compressors are designed to serve as quick , easy replacements for most 7.5 to 15 ton commercial air conditioning scroll compressors .
These compressors come with a bolt pattern , suction and discharge lines , and performance characteristics that match up directly with some competitors ’ products .
Danfoss innovations support OEMs in the challenge of improving part-load efficiency and maintaining full-load performance while transitioning to low-GWP alternatives and keeping development costs at competitive levels .
Danfoss compressors for air conditioning - a lifetime of savings
To meet the needs of an increasingly complex HVAC market , our extensive range of compressors offers functional benefits and savings throughout the lifecycle of the system , from operating costs to servicing and maintenance .
• Running costs : Danfoss technologies offer the widest portfolio for superior full and part-load efficiencies to reduce the running costs of the system .
• Service costs : The reliability , design and long working life of Danfoss compressors minimise maintenance and servicing costs while eliminating unplanned downtime .
