Description
Technical field
The invention belongs to the central air-conditioning technical field, be specifically related to a kind of oil and separate condenser.
Background technology
Continue, increase fast along with what Chinese national economy was built; Living standards of the people improve constantly; The demand of refrigeration air-conditioner is increasing; But the energy consumption of building cooling is huge, brings the increasing pressure for aspects such as the energy, electric power, environment, take energy-conservation, technology can progressively address this problem efficiently.Through experimental study and tackling key problem for many years; Refrigeration and air-conditioning technical has been obtained very big progress in some aspects; Some new technologies are just beginning to get into the practicability stage; Wherein having only minority unit adhering to technical research energy-conservation, high efficiency products, as the requisite condenser of refrigeration air-conditioner, is the most possible from now on product energy-conservation, high efficiency technical that adopts.
In refrigerated air-conditioning system, screw type refrigerating compressor needs refrigeration oil to be lubricated, and realizes sealing property simultaneously.The refrigeration oil of fair amount is vital for the safe handling that guarantees compressor.
In water-cooling screw rod formula unit; Refrigerant is compressed to high temperature and high pressure gas through refrigeration compressor; Get into condenser then; Refrigeration oil in the refrigeration compressor can together be taken out of condenser simultaneously, and the refrigeration oil in the refrigeration compressor constantly reduces and causes final damage, and system can't continue, safe handling.In order to guarantee the safe handling of compressor; Will in refrigeration compressor, guarantee the refrigeration oil of fair amount all the time; With the refrigeration oil of taking refrigeration compressor out of before getting into condenser; Utilize air-flow break-in, reduction flow velocity, the oily filter assemblies of oil separating device to filter out, the refrigeration oil that filters out forms oil droplet, under the gravity effect, flows in the dividing plate oil storage tank of built-in oil content device; Get back to compressor under pressure through return line at last, get into condenser condenses through the refrigerant that filters.
In present water-cooling screw rod formula unit; Generally adopt the oil that carries housing to separate system and restrain the two-way built-in oil content condenser that mutual group becomes to have two-layer housing with condensation; Because there is not corresponding oil level visor; To in time observing in air-conditioning system test, operation, the debug process and whether the monitoring oil level satisfies design, service requirement is brought obstacle, must not oneself thickness through increasing oily filter assemblies or adopt two-way built-in oily separation technology to be effective.
Summary of the invention
The purpose of this invention is to provide a kind of unidirectional built-in oil and separate condenser with the oil level visor; The two-way built-in oil content condenser that mutual group becomes to have two-layer housing is restrained with condensation by the oil separation system that carries housing with the solution prior art; There is not corresponding oil level visor, thickness that must be through increasing oily filter assemblies or adopt problems such as two-way built-in oily separation technology is effective.
The present invention mainly by housing, condensation tube bank, air inlet pipe, liquid outlet, and refrigerating medium import and export and form; Solving the technical scheme that its problem adopts is that unidirectional oily separation system that does not carry housing and condensation tube bank are co-located in the same horizontal cylinder, shared one deck housing, and dividing plate top is provided with unidirectional oily separation system; And rotate 30-40 ° around cylinder axis; The lower partition is provided with gripper shoe and condensation tube bank, and the condensation tube bank is array, and condensation tube bank and two ends tube plate expanded-connecting are fixed; Gripper shoe is set in the middle of the tube sheet, and the condensation tube bank places on the gripper shoe; Between unidirectional oily separation system and the condenser pipe bunchy top portion gas channel is set; , sidepiece upper and lower at cylinder is provided with air inlet pipe, liquid outlet, oil level visor and back leakage connection respectively, and the following position of oil level visor is concordant with dividing plate, is positioned at before the oily filter assemblies, and oily filter assemblies is fixed through screen; The air inlet pipe exhaust outlet apart from baffle plate apart from 50mm-70mm; The thickness of oil filter assemblies filter screen can be chosen in 100mm-150mm.Refrigerating medium is imported and exported the one or both ends that are separately positioned on cylinder.
The direction that high temperature and high pressure gas in the described gas channel gets into oil separation system orientation and gas effluent oil piece-rate system differs 180 °.
Adopt good effect of the present invention to be because have the oil level visor, can realize technically that unidirectional oil separates, and can in time monitor oil level simultaneously in system test, operation, debug process; The oily filter assemblies that employing is thinner than other technology; Strengthened the dividing plate angle of inclination, the refrigeration oil that filters out forms oil droplet more easily, under the gravity effect, flows in the dividing plate oil storage tank of built-in oil content device; Overall structure is simple; Observe, the monitoring oil level is convenient, reduces material consumption, reduce system pressure drop and reduce the unit energy consumption.
