Background technology
When air conditioner refrigerating unit operates, refrigeration oil inevitably more or less enters whole refrigeration system with refrigerant gas, participates in kind of refrigeration cycle.After particularly entering evaporimeter, the refrigeration oil being dissolved in cold-producing medium because the evaporation of cold-producing medium is deposited on base of evaporator with the form of liquid oil droplet, cannot can be got back in compressor crankcase with refrigerant gas.When refrigeration oil cannot return compressor for a long time continuously, pasta in compressor will be caused to decline, and refrigeration oil is exhausted, finally there will be the pernicious faults such as compressor oil starvation, seize even burn.In addition, one deck oil film can be formed on its heat exchanger tube surface after refrigeration oil enters evaporimeter or condenser with cold-producing medium, because this layer of oil film thermal conductivity factor is less, causes thermal resistance to increase, affect heat exchange property.
In order to ensure the operation of compressor stability and safety, reduce the refrigeration oil entered in heat exchanger as far as possible, usually an oil eliminator is set between the gas exhaust piping and condenser of refrigeration unit, separate directly return with being vented the refrigeration oil of together discharging to ensure the normal operation of compressor in compressor, and alleviate the impact of oil film on evaporimeter and condensing heat-exchange performance.The oil eliminator of this independent setting causes adapter complicated, and pressure drop increases, and efficiency reduces, and also makes the overall volume of air-conditioner set increase, cost increase simultaneously.
In order to overcome the deficiency of above-mentioned technology, there is the integrated equipment be arranged on by oil eliminator in condenser, being called built-in oil content integrated condenser.Its technical scheme is separated from the cold-producing medium gas phase of high pressure superheater by refrigeration oil in same cylinder, isolated oil directly returns compressor, and the cold-producing medium of gas phase contacts with cold heat exchanger tube and is condensed into liquid state, discharge from the liquid refrigerant outlet of bottom.Built-in oil content integrated condenser can realize the integration of oily piece-rate system and heat-exchange system, thus reduces pressure drop, improves efficiency, and system adapter is simple, and complete machine is succinct.
But, filter type oil separator is only placed in condenser by existing built-in oil content integrated condenser, structural combination and cooperation functionally both not considering, cause the flow velocity of built-in oil eliminator high, flow velocity is uneven, inferior separating effect, also has volume large in addition, the shortcomings such as process and assemble difficulty.
Chinese patent notification number is that the utility model patent of CN200961976Y discloses " condenser for threaded spindle flooded air conditioning group ", and its technical scheme lacks even gas distribution device exactly, causes gas flow rate uneven, have impact on result of use.
And the application for a patent for invention that China Patent Publication No. is CN101270945 discloses " a kind of built-in oily separate type condensing unit ", its technical scheme is also just direct makes the Horizontal-type filtering condenser that a bi-directional secondary is separated into the arc top being arranged on condenser cylindrical shell afterwards, its weak point is also cause the flow velocity in silk screen filter layer high, cold-producing medium enters condenser from the outlet at the two ends of oil eliminator, cause cold-producing medium skewness in tube bank, oil eliminator volume is large simultaneously, causes the volume of whole condenser to increase.
And for example, Chinese patent notification number is that the utility model patent of CN202013056 discloses " gas and oil separating plant being built in condenser ", it has carried out some to the subproblem in first technology and has improved, improve the distributing homogeneity on heat-exchanging tube bundle of cold-producing medium, but it is high by the speed of silk screen layer that it also exists cold-producing medium equally, cause the problems such as oily inferior separating effect, not fully in conjunction with the design feature of oil eliminator and condenser itself.
