Description
The sector of thermodynamic tanks requires more advanced and sustainable concepts that focus on higher performance, lower costs and consumption, high comfort and high versatility and ease of assembly. These needs are very representative in the Nordic countries, especially in Norway, in which demand, if not managed in an efficient and environmentally sustainable way, results in high costs and consumption levels, as well as severe environmental impact (mainly associated with CO2 emissions). Therefore, the trend is toward nearly zero energy buildings (NZEB). SAUNIER DUVAL is going to undertake this project with the objective of developing the first system for the generation and storage of DHW heat pump with natural HC refrigerant, very efficient and with the minimum environmental impact of the market, which also allows the capture alone or in combination of different heat sources (air, solar, geothermal, water renewal) and its intelligent storage in a thermodynamic tank to supply ACS.
Summary of project results
The main objective of the project was to develop a pioneer system for the generation and storage of domestic heat water (DHW) heat pumps using natural HC refrigerant (propane - R290). Its application to DHW has proven to be highly efficient and with a minimum environmental impact compared to the remaining market, with a reduction of over 99% of CO2 emissions into the atmosphere and an increase of the system performance with COP= 3.2 (the highest of the market). It's important to emphasize the performance of water temperatures of 65 ºC and the Shiftload tank concept, which provides excellent stratification and DHW comfort. The system allows for the capture alone or in combination of different heat sources. Thanks to this first experience with propane, the company is very well prepared and in an advantageous position against its competitors for the use of propane, which has shown great potential for many applications.
