| | Ammonia in small systems: testing a prototypeMar. 03, 2009 - The EU SHERHPA project developed and tested a 9 kW water-to-water heat pump running on ammonia. This third article discusses aspects of the prototype development and first results showing that small R717 systems using compact heat exchangers can give competitive COP results at a significantly reduced refrigerant charge. Although the SHERHPA project has now ended the Royal Institute of Technology plans to continue the work on small capacity ammonia systems using the experience and components developed during the project. A planned heat pump prototype will use the prototype mini-channel heat exchangers and an open compressor, together with a synchronous permanent magnet motor. Source: ammonia21.com | |
