Air Source Heat Pumps for Decarbonizing of Space Heating and Cooling: Performance Simulation with TRNSYS
Abstract
Heat pumps can play an important role in meeting global targets for energy savings and low carbon emissions. Air source heat pump is an energy-efficient technology that allows heating at different ambient temperatures. ASHPs can be used in different climates, from -25°C to +50°C. It presents the ASHP applications all over the world and highlights the measures to be taken to accelerate the use of ASHPs in buildings. The current study introduces a numerical model of the TRNSYS software and MATLAB programming to investigate the efficiency of a heat pump system in the climates of Afghanistan. The simulations incorporate hourly weather data specific to each city and detailed representations of the heat pump systems. This study calculates the heat pumps' performances and energy consumption over a year for each city, considering the dynamic interaction between the systems, the buildings, and the outdoor environments. The results provide insights into the heat pumps' efficiencies, including COP values for heating modes, annual energy consumptions, and indoor temperature profiles. Comparative analyses across the cities allow for the evaluation of the impact of different climates on the heat pumps' performances. The results provide valuable insights for making well-informed decisions regarding energy-efficient heating solutions customized for the unique climates of Afghanistan.
