To show such the thermodynamic analysis and design method clearly, the efficacy of a demonstrated PV integrated ASHP system for HVAC in Central-south China was investigated. In our work, it is not a simple combination of PV technology and air source heat pump (ASHP). The upper chain stage...

Ground-Source Heat Pumpspresents the theory and some of the most recent advances of GSHPs and their implementation in the heating/cooling system of buildings. The authors explore the thermodynamic cycle with calculation, operation regimes and economic indicators and GHG emissions of a vapor compression...
The theory of each transcritical CO2 HPWH is explained based on the working principles and thermodynamic cycles. Performance limitations of state-of-the-art CO2 HPWHs are presented with the consideration of the pinch point and the technical constraints in CO2 compressors and heat exchangers. The ...
In this work, we partially answer this question by the change of operation mode and of the choice of material. Fig. 1: Temperature (T) dependent specific heat pumping power (q) for a variety of heat pumping techniques. The specific heat pumping power is estimated by the thermodynamic ...
The coefficient of performance (COP) is defined as useful energy output divided by the required energy as input, which is a commonly adopted indicator of the thermodynamic efficiency of the cycling process and depends strongly on the operating conditions (Fig.5). The heating model (COPH) and ...
(3) The conventional arrangement also creates a thermodynamic problem in that the working gas is passed through the hot heat-exchanger at times during the cycle when it would be desirable for the working gas to be cooled and through the cold heat exchanger at times when it would be desirable...
