Abstract
|
|
|
|
| A 2-pipe collective thermal system is considered suitable only for space heating and Domestic Hot Water (DHW) distribution. However, this study investigates through dynamic simulations the extent to which space cooling (SC) is possible by cleverly using decentralised DHW storage to distribute time-dependent supply temperatures, without local boosters. The results show an 90,8% reduction in indoor temperature discomfort compared to the traditional 2-pipe system (without SC). Compared to a 4-pipe system, cooling and heating production increases by 8,2% and 19,7%, respectively, due to large shares of dissipated heat and cold. SC in 2-pipe systems has been shown to be possible, but heat and cold dissipation needs to be minimised to exploit more potential. |
