Description
Technical field
The invention belongs to full-liquid type air-conditioner set technical fields, and in particular to a kind of for the novel floating of flooded evaporator
Dynamic formula oil return apparatus.
Background technique
Flooded evaporator is the main building block of full-liquid type air-conditioner set.In the operation of full-liquid type water cooler,
Refrigeration oil in compressor understands some and follows the refrigerant gas of high temperature and pressure to enter condenser and be blended in condensed
In liquid refrigerant, then enter flooded evaporator after throttle mechanism reducing pressure by regulating flow.Due to the spy of flooded type evaporator structure
Property, the refrigerant gas flow velocity in shell side is very low, and the refrigeration oil into shell side cannot be as dry evaporator, can be by back pressure
The refrigerant gas of contracting machine brings back to compressor by certain flow velocity, this just needs to increase a set of evaporator oil return apparatus, passes through
This covering device sends the refrigeration oil that liquid refrigerant upper layer in evaporator shell side is enriched with back to compressor.
So can smoothly return to compressor into the refrigeration oil in evaporator is for a flooded evaporator
The key that can whole system operate normally, and what this was mainly determined by the control of refrigerant liquid level and the position of oil return opening.
However in a refrigeration or heat pump system operation, due to the variation of load, the liquid level of evaporator can float, and return at present
The setting of hydraulic fluid port is fixed, this results in sometimes oil return opening suction and compressor is caused to lose oil and stop less than refrigeration oil
Machine.It now proposes a kind of device, so that oil return opening is floated with the floating of liquid level, such oil return opening remains at optimum time
Oil level is set, and will play great function to guaranteeing that system oil return and system operate normally.
Summary of the invention
Aiming at the deficiencies in the prior art, the present invention provides a kind of novel float-type for flooded evaporator time
Oily device, structure is simple, and evaporator refrigeration oil oil return can be effectively ensured.
In order to achieve the above object, technical scheme is as follows:
A kind of novel float-type oil return apparatus for flooded evaporator, including fixed oil return pipe, floating type oil return pipe and
Floating ball；The section of the floating type oil return pipe is to be inverted T-type, and the floating type oil return pipe is divided into the vertical pipeline perpendicular to liquid level
The U-tube road being connected to with vertical pipeline bottom, vertical pipeline top opening are oil return outlet, and two tops on U-tube road are opened
Mouth is floating oil return mouth；The vertical pipeline of the floating type oil return pipe is covered in the outside of fixed oil return pipe, and can be along fixed
Oil return pipe moves up and down；The floating ball is connect with floating type oil return pipe, and guarantees air-tightness；When refrigerant fluid change, floating ball
It drives floating type oil return pipe to move up and down along fixed oil return pipe, floating oil return mouth is made to remain the relative position with liquid level
It is constant.
Further, the floating ball center is fixed in outside floating type oil return pipe, and guarantees air-tightness.
The utility model has the advantages that the present invention drives floating type oil return pipe to move up and down along fixed oil return pipe by floating ball, realizes and steam
Send out the effective oil return of device refrigeration oil.
Detailed description of the invention
Fig. 1 provides a kind of structural schematic diagram of novel float-type oil return apparatus for flooded evaporator for the present invention.
In figure, the fixed oil return pipe of 1-, the floating type oil return pipe of 2-, 3- floating ball, 4- limit plate, 5- floating oil return mouth, 6- times
Oil export, 7- liquid level, 8- vertical pipeline, 9-U type pipeline.
Specific embodiment
The present invention is described below with reference to specific embodiments.It will be appreciated by those skilled in the art that these embodiments are only
For illustrating the present invention, do not limit the scope of the invention in any way.
A kind of novel float-type oil return apparatus for flooded evaporator, including fixed oil return pipe (1), floating type time
Oil pipe (2) and floating ball (3)；The section of floating type oil return pipe (2) is to be inverted T-type, and floating type oil return pipe (2) is divided into perpendicular to liquid level
(7) vertical pipeline (8) and the U-tube road (9) being connected to vertical pipeline bottom, vertical pipeline (8) top opening go out for oil return
Mouth (6), two top openings of U-tube road (0) are floating oil return mouth (5)；The vertical pipeline (8) of floating type oil return pipe (2) covers
In the outside of fixed oil return pipe (1), and can be moved up and down along fixed oil return pipe (1)；Floating ball (3) center is fixed in floating type
Oil return pipe (2) is external, and guarantees air-tightness；When refrigerant liquid level (7) changes, floating ball (3) drives floating type oil return pipe (2) edge
Fixed oil return pipe (1) moves up and down, and floating oil return mouth (5) is made to remain constant with the relative position of liquid level (7).
Fixed oil return pipe (1) top is equipped with limit plate (4)；Fixed oil return pipe (1) and limit plate (4) are welded to connect simultaneously
Guarantee air-tightness, limits floating type oil return pipe (2) flying height.
Workflow of the invention:
1) refrigeration oil on evaporator top enters under the suction of jet pump (non-this patent content) from from floating oil return mouth (5)
The U-tube road (9) of floating oil return pipe (2), then the vertical pipeline (8) along floating oil return pipe (2) enters fixed oil return pipe
(1), enter jet pump through oil return outlet (6)；
2) when liquid level declines, floating oil return pipe (2) makes floating oil return mouth as floating ball (3) is along fixed oil return pipe (1) decline
(5) it keeps and the relative position of refrigerant liquid level is constant；
3) equally, if refrigerant liquid level (7) rises, floating oil return pipe (2) is as floating ball (3) is along fixed oil return pipe (1)
It rises, equally keeps floating oil return mouth (5) and the relative position of refrigerant liquid level is constant.
