The invention discloses a wave energy efficient pneumatic conversion device controlled by the constant pressure and method. Container storage and gas-liquid phase transition of working substances areutilized to compensate for the air pressure variation of the wave energy efficient pneumatic conversion device, the volatility of energy conversion is reduced, and the efficiency of the pneumatic conversion device is improved.
