In this thesis, a one-stage transcritical CO2 water-to-water heat pump is numerically and experimentally analyzed in the production of hot water for the applications of space heating and domestic hot water (DHW). Different configurations commonly used in the market are studied and compared for the same water temperatures at the heat sink (evaporator) and heat source (condenser). From now on, since in CO2 transcritical cycles does not exist phase change, the condenser is called gas cooler.

The use of models described by the ratio of two polynomial approximations with memory has been receiving particular attention by the wireless communication community. Rational models with memory require a lower number of coefficients and work better with extrapolation data than polynomial approximations. This work proposes a novel rational model with memory that, in comparison with previous approaches having the same number of parameters, can increase the modeling accuracy. The novelties of the proposed rational model, in comparison with the best available rational model, are the use of a larger set of truncation factors and the inclusion of additional terms.
