Determination of optimum high-side pressure of R744 automotive heat pump using Fibonacci search method (IEEE, 2017-06-21)This paper deals with maximizing coefficient of performance (COP) of R744 automotive heat pump. A high-side pressure variation is possible during transcritical operation employing low pressure receiver and electronic ...
(IEEE, 2017-03-23)This paper deals with coefficient of performance maximization for automotive R744 heat pump using Nelder-Mead simplex method.
(Proceedings of the 7th European Transport Research Arena 2018, 2018-04-16)Since fully electric vehicles (FEV) do not have enough waste heat for cabin heating as internal combustion engine (ICE) vehicles and hybrid vehicles do, it is beneficial to employ a reversible heat pump in FEVs. The ...
