Development of a Wind Directly Forced Heat Pump and Its Efficiency Analysis

الملخص EN

The requirements of providing electric energy through the wind-forced generator to the heat pump for water cooling and hot water heating grow significantly by now.

This study proposes a new technique to directly adopt the wind force to drive heat pump systems, which can effectively reduce the energy conversion losses during the processes of wind force energy converting to electric energy and electric energy converting to kinetic energy.

The operation of heat pump system transfers between chiller and heat that are controlled by a four-way valve.

The theoretical efficiency of the traditional method, whose heat pump is directly forced by wind, is 42.19%.

The experimental results indicated average value for cool water producing efficiency of 54.38% in the outdoor temperature of 35°C and the indoor temperature of 25°C and the hot water producing efficiency of 52.25% in the outdoor temperature and the indoor temperature both of 10°C.

We proposed a method which can improve the efficiency over 10% in both cooling and heating.
