An Installed Hybrid Direct Expansion Solar Assisted Heat Pump Water Heater to Monitor and Modeled the Energy Factor of a University Students’ Accommodation

This paper focused on the performance monitoring and modeling of a 6.0 kW, 2000 L hybrid direct expansion solar assisted heat pump (DX-SAHP) water heater used for production hot in university students’ accommodation with 123 females. The data total electrical energy consumed, volume ambient temperature, relative humidity, irradiance were obtained from acquisition systems analyzed conjunction factor (EF) system. A multiple linear regression model was developed to predict EF. EF DX-SAHP determined summation coefficient (COP) unit fraction (SF) collectors. operations system based three phases (first phase 00:00–08:00, second 08:30–18:30, third 19:00–23:30) over 24 h entire period. average per day during operation 4.38, while SF COP 0.697 3.683, respectively. accurately predicted
