PASSIVE ORGANIC MATTER WORKING MEDIUM EJECTOR REFRIGERATION METHOD

摘要

A passive organic matter working medium ejector refrigeration method, comprising: a liquid organic matter working medium in a liquid storage tank is added to an evaporator by gravity; the working medium in the evaporator is heated to evaporate, and when the temperature and pressure of the working medium reach certain values, a self-operating pressure control valve is automatically opened and an ejector starts up; after condensing, the working medium is divided into two paths, one path flowing into the liquid storage tank, and the other path flowing into a refrigeration evaporator for a refrigeration cycle, so as to generate cooled water of about 12°C; when the liquid working medium in the evaporator is completely evaporated, the pressure control valve group starts up, and the working medium in the liquid storage tank flows into the evaporator, and a certain quantity of working medium is sealed in the evaporator to repeat the above operation. The passive type organic matter working medium ejector refrigeration method utilizes 60-200°C low-temperature heat energy as a heat source, and utilizes underground water, river water, seawater or air as a cooling source, selects organic matter as a working medium, and utilizes gravity to convey the liquid working medium.
