IIR documentSummary
A novel heat pump directly driven by wind turbine is proposed by deleting the conventional intermediate power generation link. Compared with the typical wind energy – power generation – heat pump utilization method, the novel heat pump can improve the energy conversion efficiency, avoid wind curtailment, and supply energy locally by distributed energy systems. The system is consisted by four subsystems. One is the wind turbine to capture wind energy. The second one is the gearbox to transmit the energy, and drive the compressor belonging to the heat pump as the third subsystem. The forth part is the energy storage subsystem. The mathematical model is established to make out the relationships between wind turbine and heat pump. Different operating conditions are tested. The simulation results show the average primary energy ratio is higher than 150%, proving the feasibility and the high energy efficiency of the novel system.
