Patent number: 9243820Abstract: An apparatus and method for measuring concentration of a liquid-state refrigerant of a nonazeotrope refrigerant mixture. A container is disposed in such a way that a liquid-state refrigerant mixture of the nonazeotrope refrigerant mixture in a saturated state is temporarily stored with set quality. By measuring temperature and pressure of the liquid-state refrigerant mixture, concentration of the liquid-state refrigerant can be calculated from a database regarding a relationship between a saturation vapor pressure, temperature, quality, and concentration of the previously-stored nonazeotrope refrigerant mixture in the saturated state. Thus, a configuration for measuring the concentration of the liquid-state refrigerant-absorbent mixture includes a container, a temperature sensor and a pressure sensor and thus is very simple and the cost for the configuration can be reduced. In addition, the container can be easily mounted on existing equipment without disturbance of a flow.Type: GrantFiled: October 23, 2012Date of Patent: January 26, 2016Assignee: KOREA INSTITUTE OF ENERGY RESEARCHInventors: Seong-Ryong Park, Siyoung Jeong, Minsung Kim
