A kind of refrigeration system, using the multilayer flooded evaporator of above-described embodiment.
A kind of air-conditioning system, using the multilayer flooded evaporator of above-described embodiment.
The operation principle of the embodiment of the present invention is as follows：
Gas-liquid two-phase cold-producing medium enters cylinder 1 by refrigerant feed tube 3, and refrigerant is sprayed in the superiors' pallet 5.Refrigerant with
Pool Boiling Heat Transfer occurs in this layer of pallet 5 for the refrigerating medium in the superiors' heat exchanger tube 4, and some refrigerant, which is evaporated to gas and flowed into, to be inhaled
Tracheae 2, in top edge overflow to the second layer pallet 5 for the side plate 51 that residual refrigerant liquid passes through pallet 5, in second layer pallet
In 5, with the refrigerating medium in second layer heat exchanger tube 4 Pool Boiling Heat Transfer, some refrigerant evaporation occur in this layer of pallet 5 for refrigerant
For gas, gas is flowed out by the air flue 6 between the superiors' pallet 5 and second layer heat exchanger tube 4 to both sides, then passes through cylinder 1
Passage between pallet 5 flows into air intake duct 2, and unevaporated refrigerant liquid passes through this layer of pallet side in second layer pallet 5
In the top edge overflow of plate 51 to third layer pallet 5.So by that analogy, refrigerant boils in following each occurred pool of layer pallet 5
Heat exchange is risen, part of refrigerant is evaporated to gas, is flowed out by the air flue 6 between this layer of pallet 5 and lower floor's heat exchanger tube 4, another
In top edge overflow to the lower tray 5 that the unevaporated refrigerant liquid in part passes through this layer of tray side panels 51.Orlop pallet 5
The direct overflow of interior refrigerant liquid is to the bottom of cylinder 1.In the bottom of cylinder 1, refrigerant and the load in orlop heat exchanger tube 4
Pool Boiling Heat Transfer occurs for cryogen, and gas caused by evaporation is flowed out by this layer of air flue 6 to both sides, then passes through cylinder 1 and pallet 5
Between passage flow into air intake duct 2, due to refrigerant pass through the evaporation of each layer, oil be successively concentrated, orlop liquid refrigerant
Interior oil concentration highest, the higher refrigerant of oil content returns to compressor by oil return pipe 7, it is achieved thereby that reliable oil return.
Due to being provided with air flue 6 between each layer pallet 5 and the heat-exchanging tube bundle of its underpart, bubble caused by evaporation is easy to lead to
Cross air flue 6 to discharge in time, it is therefore prevented that bubble exchanges the adverse effect of hot property；Also solve tighter caused by a large amount of bubbles converge
The air-breathing solution dehumidification while migration of weight.
Restrained due to heat exchanger tube 4 is separated into Multi-layer exchanging heat by pallet 5, it is small equivalent to one in every layer of pallet 5 to expire
Solution type evaporator, the heat-exchanging tube bundle in every layer of pallet 5 is only by 1~5 row's set of heat exchange tubes into traditional flooded evaporator phase
Than greatly reducing refrigerant height of static liquid column so that influence of the hydrostatic column to the heat transfer temperature difference of base of evaporator heat exchanger tube is big
It is big to reduce, so as to improve heat exchange property.The top of the top edge of other every layer of tray side panels 51 and the heat-exchanging tube bundle of respective layer
Edge flushes with or slightly higher than the top edge, and this allows for the heat-exchanging tube bundle that liquid refrigerant can be flooded in every layer of pallet 5, so as to protect
The good heat exchange of refrigerant and heat exchanger tube 4 is demonstrate,proved.
Air flue 6 is set between each layer pallet 5 and the heat-exchanging tube bundle of its underpart, passage is provided between cylinder 1 and pallet 5, this
Allow for the charging amount that refrigerant charge is not above traditional flooded evaporator.
Refrigerant is successively concentrated by the evaporation of each layer, oil, in liquid refrigerant oil concentration in base of evaporator highest,
Because oil return pipe 7 is in the lowest part oil return of cylinder 1, compared with traditional flooded evaporator in refrigerant liquid level oil return, return
Oil concentration is greatly improved, and oil return reliability is improved, and also reduces the content of liquid refrigerant in oil return in addition, so as to carrying
High system energy efficiency also has certain effect.
The above described is only a preferred embodiment of the present invention, being not the limitation for making other forms to the present invention, appoint
What those skilled in the art changed or be modified as possibly also with the technology contents of the disclosure above equivalent variations etc.
Imitate embodiment.But it is every without departing from technical solution of the present invention content, the technical spirit according to the present invention is to above example institute
Any simple modification, equivalent variations and the remodeling made, still fall within the protection domain of technical solution of the present invention.
