Abstract
An automatic oil return system of a Freon flooded refrigeration system belongs to the technical field of refrigeration. The automatic oil return system comprises a liquid storage tank, a condensation liquid pipe, a heat gas pipe, a gas return pipe and an oil return pipe, wherein, a filter and a liquid pump are mounted on the condensation liquid pipe. The automatic oil return system is characterized in that an oil rich layer overflow pipe group is arranged in the liquid storage tank, and is connected with the oil return collector; a plate type electric heater is arranged in the oil return collector; the oil return collector is connected with the filter through an electromagnetic valve, a cut-off valve and a pipe; the filter is connected with an oil sight lens; the oil sight lens is connected to a unit low-voltage inhale collecting pipe; the oil return collector is connected the gas return pipe through the electromagnetic valve, the cut-off valve and the pipe; and the oil return collector is connected with a condenser through the cut-off valve, the electromagnetic valve and the pipe. In the utility model, the oil can be heated and segregated in the oil return collector, and is returned to the compressor, the oil returning and the oil segregating not only can be automatically achieved during the running of the compressor, but also during close-down, the oil balance of the automatic oil return system can be guaranteed effectively, less refrigeration oil is added to the Freon flooded system, the operational security of the compressor is ensured, and the operating efficiency of the system is improved.
Description
Technical field
The utility model belongs to refrigeration technology field, is specifically related to a kind of freon full-liquid type refrigeration system automatic oil return system.
Background technology
Traditional freon full-liquid type refrigeration system; When particularly adopting the remote feed flow of barrel pump; Exist fluid not separate fully; A large amount of refrigeration oils is dissolved in the system refrigerant, can not successfully get back in the compressor, causes a large amount of filling wastes, the running efficiency of system of lack of lubrication, lubricating oil lower.
Summary of the invention
The utility model provides the automatic oil return system of the higher a kind of freon full-liquid type refrigeration system of operational efficiency.
The utility model comprises liquid storing barrel, condensed fluid pipeline, hot gas duct, return-air duct, oil returning tube; Filter, liquid pump are installed on the condensed fluid pipeline, it is characterized in that being provided with in the liquid storing barrel oil-enriched layer overflow pipe group, oil-enriched layer overflow pipe group connects the oil return oil catcher; The oil return oil catcher is provided with plate electric heater; The oil return oil catcher is connected with filter with pipeline through magnetic valve, stop valve, and filter connects looks oily mirror, looks oily mirror and is connected to unit low pressure air suction collector; The oil return oil catcher is connected muffler through magnetic valve, choke valve with pipeline; The oil return oil catcher is connected with cooler with fixed attention through stop valve, magnetic valve and pipeline.
The utility model can be with oil heating and separating and get back to compressor in the oil return oil catcher; It can not only realize dividing oily oil return automatically when compressor operating; When shutdown, also can realize realizing automatically dividing oily oil return, the oily balance of effective safeguards system, the addition of minimizing freon full-liquid type system refrigeration oil; Guarantee the security of operation of compressor, improve running efficiency of system.
