Abstract
A state analysis device and a state analyzer system include a specific state determination unit that determines specific state information representing a state of refrigerant at a specific position in a refrigeration circuit and a normal region determination unit that determines a normal region in a state space within which the specific state information is present when an air-conditioning apparatus operates under a normal state. The state analysis device and the state analyzer system allow a display to display the specific state information and the normal region.
