Aim of this work is to define a dynamic model developed in the Trnsys software environment where a biomass boiler and two micro-CHP gasifiers are considered as heat source for a detached house. The selected case study is a detached house of about 240 m2near Bologna, Northern Italy, where the HVAC system is currently equipped with a diesel oil boiler with 40 kW of thermal power. The building is connected to a farm and the total electrical consumption is about 13850 kWh/year. The thermal energy demand was calculated and validated in Trnsys using measured diesel oil consumption data. Two different retrofitting solutions for the heating system have been investigated: biomass boiler and micro-CHP gasifiers. Results show the capability to use biomass boiler and micro-scale gasifiers as heat source for the building with a wood consumption of 23 and 86 ton/year respectively. The gasifier electricity production is greater than the electrical demand and an extra energy of 64800 kWh/year is injected into the grid. The cost-benefits economical assessment of these retrofitting solutions is reported considering subsidies for renewable energy production.

Abstract

Aim of this work is to define a dynamic model developed in the Trnsys software environment where a biomass boiler and two micro-CHP gasifiers are considered as heat source for a detached house. The selected case study is a detached house of about 240 m2near Bologna, Northern Italy, where the HVAC system is currently equipped with a diesel oil boiler with 40 kW of thermal power. The building is connected to a farm and the total electrical consumption is about 13850 kWh/year. The thermal energy demand was calculated and validated in Trnsys using measured diesel oil consumption data. Two different retrofitting solutions for the heating system have been investigated: biomass boiler and micro-CHP gasifiers. Results show the capability to use biomass boiler and micro-scale gasifiers as heat source for the building with a wood consumption of 23 and 86 ton/year respectively. The gasifier electricity production is greater than the electrical demand and an extra energy of 64800 kWh/year is injected into the grid. The cost-benefits economical assessment of these retrofitting solutions is reported considering subsidies for renewable energy production.
