Decarbonizing rural residential buildings in cold climates: A techno-economic analysis of heating electrification[1][edit | edit source]

https://doi.org/10.1016/j.enbuild.2021.111284

Abstract

This study analyses the techno-economic characteristics of sustainable heating electrification in remote rural, residences in colder region with no supplies of natural gas. The aim of this study is decarbonization of the heating sector and the urgent need for substituting propane in the U.S. Upper Midwest. For this study the modelling of buildings is done under four stages. A parametric solar photovoltaic (PV) size analysis is carried out at each electrification level, and the total life cycle cost, renewable fraction, and greenhouse gas (GHG) emissions are computed using the primary electricity supply for each building type. It also includes multidimensional sensitivity studies stress-test cost-optimal solutions.

Summary

  • Combination of solar PV with heat pumps can reduce 50% of GHG emission from the residential building and can reach up to 90%.  
  • Electrification is considered as most suitable and economical solution for decarbonization in cold region.

PVT based solar assisted ground source heat pump system: Modelling approach and sensitivity analyses[2][edit | edit source]

https://doi.org/10.1016/j.solener.2019.09.044

Abstract

In this study mathematical modelling and computer-based simulations was done for which the TRNSYS was used to model a PVT-based solar-assisted ground source heat pump system and run sensitivity tests. Experimental information was used to validate a unique very shallow bore field, whereas a transient model that had been experimentally confirmed was employed for the PVT collectors whereas for the heat pump model, the simulation platform coupled manufacturer performance data with a creative approach. For the heating load, a single-family home with a domestic hot water demand was assumed, and weather data from Birmingham, West Midlands, UK, was used. The yearly specific productivity metric was used to assess the simulation results. The influence of the parametric variation on the system's energy performance could be clarified in details using the proposed evaluation approach. it was discovered. The sensitivity analysis is done based on six parameters.

Modeling of Solar Assisted Heat Pumps Combined with Photovoltaic Thermal Modules[3][edit | edit source]

Abstract

This study includes the performance of a solar assisted heat pump combining photovoltaic thermal (PV/T) modules. The model was developed in MATLAB, with real components to accurately forecast SAHP performance as a function of design factors such as number of PV/T modules and ambient circumstances i.e., solar irradiance and ambient temperature. Additionally, a tool for optimization was used in conjunction with the model to change the water flow rate that circulates through the PV/T panels in order to maximize COP (Coefficient of Performance).

Combinations of heat pump and photovoltaics for renovated buildings[4][edit | edit source]

https://doi.org/10.1051/e3sconf/201911101003

Abstract

The purpose of this research is to analyze hybrid heating systems for use in newly remodeled homes that include an air source heat pump, a storage tank, and a photovoltaic (PV) system. Through the use of dynamic system simulations in TRNSYS for a renovated single-family home, it is possible to determine the potential for reducing the energy consumption of the heat pump from the grid by targeted operation of the speed-controlled compressor with electricity from PV. This is done under the assumption that the existing radiator heating system is left in place and that, as a result, relatively high supply temperatures are required.

Techno-economic analysis of combined heat pump and solar PV system for multi-family houses: An Austrian case study[5][edit | edit source]

https://doi.org/10.1016/j.esr.2021.100666

Abstract

In order to pinpoint the crucial economic factors affecting profitability and offer policy recommendations, this study offers a parametric technoeconomic analysis of PV + HP systems. Black box efficiency models for the HP and PV are simulated with hourly time steps, and demand from the Building Mimic Generator is used to model a case study in Vienna. The technical models in various simulation tools are combined with a thorough economic model to create a comprehensive system model. Consequently, it is possible to assess the solutions' life cycle cost effectiveness considering the subsidies, price of natural gas capital costs.  The findings demonstrate that both ground-source and air-source heat pumps are currently financially viable with PV under the current programmes. The reduction of carbon emission can also be done up to 50% for multi-family houses by the use of heat pumps.

Techno-economic analysis of control algorithms for an exhaust air heat pump system for detached houses coupled to a photovoltaic system[7][edit | edit source]

https://doi.org/10.1016/j.apenergy.2019.04.080

Abstract

A simulation-based case study of a new detached home in Sweden is done using TRNSYS 17 which includes an exhaust air heat pump and a solar PV. This study examines the operational control strategies for the heating system and "smart" utilization of energy storage. The goal of developing rule-based control algorithms, which are simple to integrate into contemporary heat pump controllers, was to reduce final energy consumption and increase self-consumption by utilizing the thermal storage of the building, the hot water tank, and electrical storage. It also makes use of forecasts data for the short-term weather and the price of electricity. An electric heater is used as a backup for both space heating and hot which impacts the system's energy balance significantly. All outcomes were compared to those for this system, which was employed as a base case together with a separate photovoltaic system.
