| Abstract | This paper summarizes the field performance of a hybrid system (gas furnace with electric air source heat pump) operating with smart switching controls. Smart switching controls enable the system to
switch from heatpump to natural gas backup during space heating operation, depending on the following. Outdoor air temperature Utility rates and time of use Performance of the heat pump Performance of the natural gas furnace The paperpresents overall
energy savings, cost savings and GHG reductions. It identifies opportunities for improving space heating performance and highlights an early market entry opportunity for this type of system. |
| Summary | (Plain Language Summary, not published)
This paper discusses a hybrid heating system that combines a gas furnace with an electric air source heat pump. What's special about this system is the
"smart switching" controls it uses. These controls allow the system to decide whether to use the heat pump or the natural gas backup for heating based on factors like:
1. The temperature outside.
2. Utility rates and time of use (when energy
costs are lower).
3. How well the heat pump and gas furnace are performing.
The study looks at how much energy and cost savings this system provides and how it reduces greenhouse gas emissions. It also explores ways to make the heating system
even more efficient and mentions that this technology has great potential in the market.
In simple terms, this research is about a clever heating system that can switch between electricity and natural gas to keep you warm, depending on what's most
efficient and cost-effective. It's important because it can save energy, money, and help reduce our impact on the environment. |
