Abstract
The utility model discloses an air source heat pump multi-platform parallel connection compressor average steam and liquid separator which can make every compressor have uniform steam suction quantity and uniform oil return quantity. The steam and liquid separator includes a separating container, a coolant steam inlet pipe is provided at the top of the separating container, a plurality of coolant steam outlet fitters are provided at the upper part of the lateral wall of the separating container, each coolant steam outlet fitter is communicated to the corresponding compressor; an oil collection cup is provided at the bottom of the separating container, a plurality of oil return pipes are led out from the oil collection cup, the oil return pipe is communicated to the corresponding coolant outlet fitter. The utility model not only achieves the object of equalizing the steam suction quantity of a plurality of paralleled compressors, but also ensure the equal oil return and thorough lubricating of each compressor, to improve the reliability and service life of the compressor.
Description
Technical field
The utility model relates to many compressors in parallel of a kind of air source heat pump and divides equally vapour, liquid/gas separator.
Background technology
For net for air-source heat pump units, vapour, liquid/gas separator are one of important in the refrigeration system, indispensable parts.Its function be unit when moving defrosting in the winter time and switching liquid refrigerants be stored in this container, and can directly not enter compressor, cause the compressor liquid hammer.In addition, unit is normally in service, and owing to the lubricating oil that sucks compressor from evaporimeter must be to be introduced into vapour, liquid/gas separator, most lubricating oil sink to its bottom easily, and therefore, the oil return of vapour, liquid/gas separator design and making are very important.But because design and make experience problem, vapour, liquid/gas separator oil return design are improper, and Crew Cooling System does not freely cause the compressor situation of burning often to take place because of oil return.The vapour of present air source heat pump, liquid/gas separator is for the refrigeration system of separate unit compressor, as long as vapour, the oil return design and the making of liquid/gas separator correctly are to satisfy instructions for use, a but refrigeration system that composes in parallel for multiple compressors, because the multiple compressors parallel transistor is different in size, turning round etc. of pipe, local resistance loss that causes and pipeline friction loss differ, the steam absorbing amount of every compressor differs, efficient is affected, simultaneously because the oil return of compressor is unbalanced, cause the compressor lubricant oil can not balance, in service all the year round, have part compressor oil starvation, influence the service life of compressor.Therefore, for the refrigeration system of multiple compressors parallel connection, the oil return of the every compressor of balance is a scabrous problem.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provides a kind of and makes many compressors in parallel of many air source heat pumps that every compressor steam absorbing amount is even, recirculating oil quantity is impartial divide equally vapour, liquid/gas separator.
The technical scheme that the utility model adopted is: the utility model comprises separation container, be provided with the refrigerant steam inlet pipe at the top of described separation container, top at the sidewall of described separation container is provided with a plurality of refrigerant steam outlet pipes, and each refrigerant steam outlet pipe is communicated with corresponding compressor; Bottom at described separation container is provided with catchment cup, leads to many oil return pipes on the described catchment cup, and described oil return pipe is connected with corresponding refrigerant steam outlet pipe.
Described refrigerant steam inlet pipe stretches into the cavity inside of described separation container.
Described a plurality of refrigerant steam outlet pipe is evenly distributed on the sidewall of described separation container, and described many oil return pipes are evenly distributed on the described catchment cup.
Many compressors in parallel of described air source heat pump are divided equally vapour, liquid/gas separator and are also included outside support, and described separation container is arranged on the described support.
The beneficial effects of the utility model be mainly reflected in following some:
1,, has the efficient height, volume is little because the steam inlet pipe of vapour, liquid two-phase refrigerant advances from the crown center of vapour, liquid/gas separator, and the return tube that connects compressor is designed to go out from the top, side of vapour, liquid/gas separator, compares with conventional vapour, liquid/gas separator.
2, every compressor is all arranged independently steam inlet pipe (being the steam outlet pipe in vapour, the liquid/gas separator), and the local resistance of pipe is suitable with on-way resistance, and steam absorbing amount is even, reaches many compressors in parallel of refrigeration system and has identical operational efficiency.
3, the oil return pipe independent design of vapour, liquid/gas separator, the return tube of every compressor has all designed an independent oil return pipe, the oil return drag losses is suitable, the recirculating oil quantity equalization, refrigeration system by many compressors in parallel is in operation owing to the oil return equilibrium like this, has guaranteed the normal service life of every compressor of the refrigeration system that multiple compressors composes in parallel.
Description of drawings
Fig. 1 is the structural representation of the utility model outside;
Fig. 2 is the structural representation of the utility model inside.
The specific embodiment
As depicted in figs. 1 and 2, the utility model comprises support 6 and separation container 1, separation container 1 is arranged on the support 6 that play supporting role, be provided with refrigerant steam inlet pipe 3 in the crown center position of described separation container 1 and stretch into the inside of separation container 1, it connects the cross valve of refrigeration system, and the refrigerant of vapour, liquid two-phase enters vapour, liquid/gas separator from refrigeration system by refrigerant steam inlet pipe 3.Top at the sidewall of described separation container 1 is provided with a plurality of refrigerant steam outlet pipes 2, the several platform numbers according to compressor of pipeline are determined. existing is example (promptly two compressors are in parallel) with two refrigerant steam outlet pipes 2, two refrigerant steam outlet pipes 2 respectively are arranged on the both sides on the wall top of separation container 1, and each refrigerant steam outlet pipe 2 is communicated with corresponding compressor; Be provided with catchment cup 4 in the bottom of described separation container 1, lead to two oil return pipes 5 on the described catchment cup 4, described oil return pipe 5 is connected with the corresponding refrigerant steam outlet pipe 2 in both sides, as increasing the number of refrigerant steam outlet pipe 2, its oil return pipe 5 corresponding increases.
It is to be exclusively used in the particular component that two or multiple compressors compose in parallel a refrigeration system that many compressors in parallel of the air source heat pump of said structure are divided equally vapour, liquid/gas separator, and it has solved vapour that present multiple compressors refrigeration system in parallel still adopts conventional refrigeration system, liquid/gas separator because the unbalanced shortcoming that causes the part compressor efficiency not to be not fully exerted of suction vapour; Because the design of special oil return wherein, the oil return equilibrium of every compressor has guaranteed that arbitrary compressor of the refrigeration system that two or multiple compressors compose in parallel is fully lubricated, the reliability and the service life of having improved compressor.
