Performance of Air Source Heat Pump Using the TRNSYS Simulation Program
Keywords:
ASHP, Coefficient of Performance (COP), SPF, TRNSYS, MATLAB, Afghanistan
Abstract
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. The selected heat pump model is an air-source heat pump with specified heating and cooling capacities. A heat pump stands as one of the most widely used devices for converting energy and supplying essential heating and cooling to buildings throughout cold and warm seasons. It is gaining popularity due to its ability to harness clean energy from the environment rather than depending on fossil fuels. This feature makes it more appealing. It can extract heat from the surrounding lower-temperature air and convert it into higher-temperature heat, which can subsequently be utilized for heating structures or generating hot water. However, a significant factor influencing its performance is the combination of high humidity and low outdoor temperatures, which results in a noticeable decrease in the efficiency of the ASHP. 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.
