Abstract

The invention discloses an electricity, heat and cool co-productive compressed air energy storage apparatus and method, wherein an air storage chamber and an air-water heat exchanger are connected intandem between the compressor and the heat regenerator, the heating tube in the air storage chamber is used for transmitting the heat energy carried by the air to the heat transfer medium, and supplying heat to the outside through the water channel of the air-water heat exchanger, an air is also connected between the compressor and the heat regenerator, the air flowing out from the air storage chamber flows through the air duct of the air-water heat exchanger and the hot air channel of the heat regenerator, which is cooled down and enters the air turbine for working by expansion, driving the electric generator for power generation, and transforming the air compression energy into electrical energy.

Description

1. Technical field [0001] The invention relates to a device and method for storing and utilizing electric energy, in particular to a compressed air energy storage device and method for cogeneration of electric heating and cooling. 2. Background technology [0002] The currently used compressed air energy storage device (Compressed Air Energy Storage), referred to as CAES, its structure is as follows figure 1 As shown, in the existing energy storage mode, the generator 2 also functions as the electric motor 2', which is located between the gas turbine 3 and the compressor 1, and is connected with the compressor 1 and the gas turbine 3 by a clutch . During the energy storage process, the motor 2' is connected to the compressor 1, and the surplus electric power is driven by the motor 2' to drive the compressor 1 to inject compressed air into the air storage chamber 6, converting the electric energy into air compression energy. In the process of power shortage and supplementar...
