摘要： An oil content measuring device measures the oil content of a refrigerant in a supercritical or a vapor phase state. A refrigeration system uses the oil content measuring device. The oil content measuring device has an electrostatic capacity measuring device for measuring an electrostatic capacity of the refrigerant containing a refrigerating machine oil, a density measuring device for measuring a density of at least one of the refrigerant and the refrigerating machine oil, a computing device for performing a computation on correlation characteristics between the electrostatic capacity and an oil content which indicates the ratio of the amount of the refrigerating machine oil to the amount of the refrigerant containing the refrigerating machine oil, using the density measured by the density measuring device. An oil content determining device determines an oil content at the measuring time from an electrostatic capacity using the correlation characteristics obtained by the computing device.

摘要： Thin film thermal oxidative engine oil or other oleaginous liquid deposit device has an oleaginous test liquid placement volume; a heatable depositor surface in liquid communication with the volume; a supply for at least one of an oxidant and another substance which can adversely affect the test liquid; and a relatively thin film forming unit which delivers the test liquid to the depositor surface in a relatively thin film. Thin film thermal oxidative engine oil or other oleaginous fluid deposit method is also provided, which includes providing an oleaginous test liquid in an oleaginous test liquid placement volume; providing a depositor surface and heating said surface; delivering the test liquid as a relatively thin film to the heated depositor surface; providing to the test liquid an oxidizing and/or other substance which can adversely affect the test liquid; and observing any deposits or other activity thereabout. The invention is useful in oil testing.
