Linear Regression Analysis and Techno-Economic Viability of an Air Source Heat Pump Water Heater in a Residence at a University Campus

This study quantifies the potential of a 4.0 kW air source heat pump (ASHP) unit retrofitted to 12.0 kW, 1000 L electric boiler coupled storage tank. A data acquisition system was built monitor performance and ASHP water heater. The annual electrical energy saving load factor reduction from because retrofit 34,805.94 kWh 0.124. net present value payback period 1.60 years. Wilcoxon rank sum test employed compare both volumes hot consumed by two systems. Linear regression models daily systems were established. results should be great management universities that are considering energy-efficient interventions with significant return on investment.
