Abstract:
A measurement apparatus (100), which is arranged on a pipe (101), and is configured to measure the liquid content of a medium within the pipe (101); said apparatus comprises: a light transmission member (210), a light generation device (203), and a light reception device (204); the light generation device (203) is configured to emit emission light toward the light transmission member (210) that passes through an outer boundary wall (214) of the light transmission member (210) and has a preset emission angle, and the light reception device (204) is configured to receive reflection light after the emission light is reflected by an inner boundary wall (215) of the light transmission member (210). The measurement apparatus (100) can directly detect whether liquid is carried in a gaseous refrigerant exiting from a evaporator, as well as measure the amount of carried liquid. The refrigeration system can adjust a throttling apparatus in a timely manner according to a measured result, and prevents the performance of the refrigeration system and a compressor from being affected.
