Heat pump or cooling system with direct wind power drive for heating and cooling without external power is of compact construction and saves compressor drive energy

摘要

The system has a rotor (5) that drives a compressor (3) connected via a coolant circuit directly to an evaporator (1), an expansion valve and a condenser (2). The compact system is mounted on a rotary plate (8). In heating mode the evaporator acts as the wind vane and in cooling mode the condenser acts as the wind vane.
