| Abstract: | The experiments and theoretical analysis have been worked out on the operation characteristics of transcritical CO 2 cycle water source heat pump in variable conditions and on the influence of the dynamic system characteristics of the external heat source properties and operation pressures. The isentropic efficiency of the CO 2 compressor,heat transfer effectiveness of gas cooler and evaporator and the influence on dynamic characteristics of the system have been obtained by fitting the experimental results. The properties of the CO 2 transcritical water source heat pump have been analyzed base on the experimental data,and the system regulation methods have also been discussed. |
