Air conditioner compressor oil replenishment device

Abstract

The invention discloses an air conditioner compressor oil recharging device, relates to the field of air conditioner maintenance equipment and provides the air conditioner compressor oil recharging device which is used for dynamically recharging oil to an air conditioner in use and in oil shortage. The air conditioner compressor oil recharging device comprises an oil containing vessel, an oil recharging stop valve, an entry stop valve, an exit stop valve and an oil containing hopper, wherein one connector of the oil recharging stop valve is connected with the upper part of the oil containing vessel through a pipeline, the other connector of the oil recharging stop valve is connected with the oil containing hopper, one connector of the entry stop valve is connected with the upper part of the oil containing vessel through the pipeline, the other connector of the oil recharging stop valve is a refrigerant entry, one connector of the exit stop valve is connected with the lower part of the oil containing vessel through the pipeline, and the other connector of the exit stop valve is a compressor connector. The air conditioner oil recharging device takes full advantage of the power generated by the air conditioner compressor or uses the high pressure of a refrigerant, so that cold oil can be conveniently supplied into the air conditioner in oil shortage.

Description

technical field [0001] The invention relates to the field of air conditioner maintenance equipment, in particular to an oil supply device for an air conditioner compressor. Background technique [0002] The refrigeration cycle of the air conditioner relies on the compressor to generate power, provide a pressure difference, and promote the refrigerant to flow through various components and return to the compressor to complete a refrigeration cycle. At the same time, the refrigeration oil is also involved in the circulation. Refrigeration oil lubricates, seals and cools the compressor itself. Because some commercial air conditioners do not have an oil separator, the high-temperature and high-pressure oil-containing refrigerant gas will continuously spray the various components of the refrigeration system. Due to the viscosity of the oil and the dead angle of the cavity of each component, even if the oil return system is well designed, it is inevitable that there will be some ...

Problems solved by technology

Because some commercial air conditioners do not have an oil separator, the high-temperature and high-pressure oil-containing refrigerant gas will continuously spray the various components of the refrigeration system. Due to the viscosity of the oil and the dead angle of the cavity of each component, even if the oil return system is well designed, it is inevitable that there will be some oil. It is no longer possible to circulate back to the oil tank of the compressor through the system. As the running time increases, the oil in the oil tank will become less and less, and the compressor will be burned due to severe oil shortage.
