Air conditioner with expansion turbine power generation device

Abstract

The invention relates to an air conditioner with an expansion turbine power generation device. The air conditioner with the expansion turbine power generation device comprises a compressor on the air conditioner, a coolant in the compressor, an evaporator and a power supply system of the air conditioner. An expansion turbine communicated with a high pressure discharge port is arranged on the high pressure discharge port of the compressor, the expansion turbine is provided with a turbine blade rotation central shaft, a magnetic force generator is arranged at the output end of the turbine blade rotation central shaft in transmission connection mode, and current generated by the magnetic force generator is output to the power supply system of the air conditioner. Kinetic energy of high pressure air flow generated by the coolant when the air conditioner is operated is indirectly converted into electric energy which can be used by the power supply system of the air conditioner, an existing expansion valve is replaced by a combined device to achieve the reverse Carnot cycle principle, and energy consumption of the air conditioner is reduced. Due to the fact that pressure of the coolant compressed by the compressor of the air conditioner is continuous and stable, and the air conditioner can obtain continuous and stable electric energy output and is strong in practicability.

Description

technical field [0001] The invention relates to the technical field of turbine power generation, in particular to an air conditioner with an expansion turbine power generation device. Background technique [0002] With the improvement of people's quality of life and the improvement of consumption level, the requirements for indoor environment are also continuously improved. As a daily necessity, air conditioners have entered thousands of households, and their demand is increasing. During the heat exchange process of the refrigerant inside the air conditioner, when the refrigerant discharged from the compressor is compressed and evaporates from a liquid state to a gas state, a large amount of high-pressure airflow will be generated. [0003] The traditional method is to install an expansion valve and throttling to create conditions for refrigerant evaporation, but the high-pressure airflow blocked outside the expansion valve for throttling is not fully utilized and wasted. ...

AI Technical Summary

Problems solved by technology

[0006] The technical problem to be solved by the present invention is: to overcome the defect that the existing expansion valve wastes the kinetic energy of the high-pressure airflow generated when the refrigerant evaporates, and to provide a method for fully utilizing the kinetic energy of the high-pressure airflow generated when the refrigerant evaporates. An air conditioner that replaces the existing expansion valve to realize the reverse Carnot cycle principle of the air conditioner, saves energy and reduces energy consumption
