Description
Technical field
The utility model relates to a kind of helical-lobe compressor earth source heat pump unit, and especially a kind of evaporimeter is for drenching the pouring membrane type earth source heat pump unit of membrane type heat exchanger.
Background technology
In the ground source heat pump technology field, the large-scale unit of helical-lobe compressor obtains application more and more widely, existing set heat exchange device mainly is dry evaporator and flooded evaporator, wherein the dry evaporator machine set system is simple, and is reliable, but because of cold-producing medium one-tenth gas-liquid mixed state in pipe, less with the heat transfer coefficient of heat exchange tube wall, because of the cold-producing medium flow velocity is bigger, must make evaporator outlet gas that the higher degree of superheat is arranged, need bigger heat exchange area; The flooded evaporator heat exchanger tube is immersed in the liquid refrigerant, cold-producing medium is boiling outside pipe, the coefficient of heat transfer improves greatly, the efficient of whole unit is higher, but evaporimeter inner refrigerant boil-off gas flow velocity is lower, the refrigeration oil of sneaking in the evaporimeter can't return compressor naturally, and therefore needing increases oil return system, and refrigerant charge is far away more than dry evaporator.Therefore develop a kind of efficiency height, novel earth source heat pump unit reliable, that refrigerant charge is few is very important.
Summary of the invention
Problem to be solved in the utility model provides a kind of efficient, reliable, pouring membrane type earth source heat pump unit that refrigerant charge is few.
For addressing the above problem, the utility model by the following technical solutions:
A kind of pouring membrane type earth source heat pump unit, comprise compressor, shell and tube condenser, oil eliminator, injector and pouring kestner long-tube evaporator, described compressor outlet is connected by pipeline with the oil eliminator import, the oil eliminator outlet is connected with the shell and tube condenser import, the shell and tube condenser outlet is connected with the pouring kestner long-tube evaporator, drenching the kestner long-tube evaporator outlet is connected with compressor inlet, drenching the kestner long-tube evaporator oil return opening is connected with injector, the injector outlet is connected with compressor inlet, the oil return opening of external oil eliminator is connected with injector, described pouring kestner long-tube evaporator comprises that peripheral hardware drenches liquid pump and liquid distributor, is provided with the pouring membranous disc below liquid distributor.
Below be the further improved technical scheme of the utility model:
Described liquid distributor comprises main liquid distributor and interior pouring liquid circulation liquid distributor.Main liquid distributor and interior pouring liquid circulation liquid distributor adopt different structure respectively, and refrigerant liquid is evenly distributed.
Described pouring membranous disc comprises liquid storage dish and the even liquid disc that is superimposed, and is filled with cloth liquid filler between liquid storage dish and the even liquid disc.
The bottom of described liquid storage dish and the bottom of even liquid disc are respectively equipped with several through holes.
Described shell and tube condenser is provided with device for drying and filtering and electric expansion valve with the pipeline that the pouring kestner long-tube evaporator is connected.
The utility model is by drenching the even cloth liquid of membranous disc, in evaporimeter, form the liquid film that evenly flows on the heat exchanger tube, has higher heat transfer coefficient, the unevaporated refrigerant liquid of base of evaporator drenches the liquid pump start-stop by liquid-level switch control realizes reducing liquid level in the evaporimeter, evaporimeter internal memory liquid measure is significantly reduced, and the bottom oil content is increased, and improve the injection effect greatly, reduce the injection time.Therefore this large-scale pouring membrane type earth source heat pump unit efficiency height, reliable, refrigerant charge is few, is better than the earth source heat pump unit of other form.
Below in conjunction with accompanying drawing the utility model is further described.
