Abstract
A measurement apparatus arranged on a pipe is configured to measure liquid content of a medium within the pipe. The apparatus includes a light transmission member, a light generation device, and a light reception device. The light generation device is configured to emit emission light toward the light transmission member such that it passes through an outer boundary wall of the light transmission member and has a preset emission angle. The light reception device is configured to receive reflection light after the emission light is reflected by an inner boundary wall of the light transmission member. The measurement apparatus can detect whether liquid is carried in a gaseous refrigerant exiting from an evaporator and measure the amount of carried liquid. The refrigeration system can adjust a throttling apparatus according to a measured result, and prevents the performance of the refrigeration system and a compressor from being affected.
