Air conditioner oil adding and subtracting device, method for adding oil to air conditioner and method for reducing oil

Abstract

The invention relates to an air-conditioner oil adding and reducing device and oil adding and reducing methods for an air conditioner. The oil adding and reducing device comprises an oil collecting tank, a first connecting pipe, a second connecting pipe, a third connecting pipe and a fourth connecting pipe, wherein the first end of the first connecting pipe is communicated with the top of the oil collecting tank, and the second end of the first connecting pipe is suitable for being communicated with the output end of an oil separator of the air conditioner; the third end of the second connecting pipe is communicated with the bottom of the oil collecting tank, and the fourth end of the second connecting pipe is suitable for being communicated with the output end of an evaporator of the air conditioner; the fifth end of the third connecting pipe is communicated with the bottom of the oil collecting tank, and the sixth end of the third connecting pipe is suitable for being communicated with the oil return end of the oil separator; the seventh end of the fourth connecting pipe is communicated with the top of the oil collecting tank, and the eighth end of the fourth connecting pipe is suitable for being communicated with the output end of the evaporator of the air conditioner; a first stop valve is disposed on the first connecting pipe; a second stop valve is disposed on the second connecting pipe; a third stop valve is mounted on the third connecting pipe; a fourth stop valve is disposed on the fourth connecting pipe. By means of the air-conditioner oil adding and reducing device and the oil adding and reducing methods for the air conditioner, refrigerant oil in the air conditioner can be quantitatively added or reduced.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner oil adding and removing device, an air conditioner oil adding method and an oil reducing method. Background technique [0002] When the air conditioner is running, it needs the participation of refrigerating oil, and the amount of refrigerating oil in the air conditioning system has a great influence on the performance and reliability of the whole machine. In the matching experiment of the air conditioner, there is often a phenomenon that the overall performance of the air conditioner is attenuated due to too little or too much refrigeration oil. But it is difficult to quantitatively add or release the refrigerant oil in the air conditioner system to adjust the performance of the air conditioner to a better state. At the same time, regarding the maintenance of the air conditioner, there is also the problem that the refrigerating oil in the air conditi...

But it is difficult to quantitatively add or release the refrigerant oil in the air conditioner system to adjust the performance of the air conditioner to a better state

At the same time, regarding the maintenance of air conditioners, there is also the problem that the refrigerated oil in the air conditioner system cannot be treated quantitatively.
