The aim is to design and optimise a transcritical CO2 air-source heat pump for delivering high-temperature hot water.
Thermodynamic modelling and numerical optimisation of a heat pump system
Component-sizing methodology established using AMESim 2404
Parametric investigations on various operational conditions through 140 simulations
Heating capacity achieved: 100–121 kW
Coefficient of performance (COP) ranged from 2.7 to 3.3
Optimal discharge pressure found at approximately 11.2 MPa, with stable COP
