Description

The cold water source pump of the built-in oil eliminator of a kind of condenser
Technical field
The utility model relates to refrigeration plant, is specifically related to the cold water source pump of the built-in oil eliminator of a kind of condenser.
Background technology
At present, the oil eliminator that cold water (heat pump) unit of employing downward film evaporator is selected is generally external, equally parallel with evaporimeter, condenser and independently exist, for whole cold water (heat pump) unit, inevitably can take a part of volume more.
Utility model content
The purpose of this utility model is the present situation for current falling film type cold water (heat pump) unit, proposes the cold water source pump of the built-in oil eliminator of a kind of condenser.Realization reduces unit floor space, reduces the object that unit height has been convenient to transportation.
The technical solution adopted in the utility model is: comprise the helical-lobe compressor that forms successively closed-loop path, downward film evaporator, condenser and electric expansion valve, described condenser inner and upper is provided with oil eliminator, described oil eliminator is " V " character form structure on condenser radial section, " V " character form structure open top of described oil eliminator is connected with air inlet pipe, described air inlet pipe is connected with helical-lobe compressor, " V " character form structure bottom of described oil eliminator is connected with fuel feed pump, described fuel feed pump is connected with helical-lobe compressor, in described oil eliminator, be provided with metal screen.
Further preferred structure, is provided with air flow passage between described oil eliminator and condenser shell.
Further preferred structure, described condenser bottom is connected with feed pipe, and described feed pipe is connected with downward film evaporator.
The utility model adopts falling film type cold water (heat pump) unit of the built-in oil eliminator of condenser without arrange independent oil eliminator in whole cooling cycle system, therefore can reduce machine packet size, be convenient to transportation and reduce the floor space of handpiece Water Chilling Units in client's machine room.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the built-in oil separator structure schematic diagram of condenser.
In figure, 1-helical-lobe compressor, 2-downward film evaporator, 3-electric expansion valve, 4-condenser, 5-oil eliminator, 6-air inlet pipe, 7-metal screen, the liquid refrigerator oil of 8-, 9-feed pipe, 10-fuel feed pump, 11-circulation passage.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, is convenient to be well understood to the utility model, but they do not form and limit the utility model.
As Fig. 1, shown in Fig. 2, the utility model comprises the helical-lobe compressor 1 that forms successively closed-loop path, downward film evaporator 2, condenser 4 and electric expansion valve 3, described condenser 4 inner and upper are provided with oil eliminator 5, described oil eliminator 5 is " V " character form structure on condenser radial section, " V " character form structure open top of described oil eliminator 5 is connected with air inlet pipe 6, described air inlet pipe 6 is connected with helical-lobe compressor 1, " V " character form structure bottom of described oil eliminator 5 is connected with fuel feed pump 10, described fuel feed pump 10 is connected with helical-lobe compressor 1, in described oil eliminator 5, be provided with metal screen 7.Described condenser 4 bottoms are connected with feed pipe 9, and described feed pipe 9 is connected with downward film evaporator 2.Between described oil eliminator 5 and condenser 4 housings, be provided with air flow passage 11.
Operation principle of the present utility model: first the HTHP cold media gas that is rich in refrigerator oil of discharging from helical-lobe compressor 1 enters the air inlet pipe 6 directly over condenser 4, and this air inlet is the import of built-in oil eliminator 5, directly over " V " shape.Enter oil eliminator 5 thereupon, through of short duration the flowing in oil eliminator 5, the HTHP cold media gas bottom of being rich in refrigerator oil arrives the top of this metal screen 7 through metal screen 7, refrigerator oil particle in cold media gas is attached on metal screen 7, and drip downwards under the effect of gravity, liquid refrigerator oil 8 is formed on the bottom that converges in oil eliminator, then under the effect of pressure energy, passes through fuel feed pump 10 to helical-lobe compressor 1 fuel feeding, and moving component is lubricated.The circulation passage 11 of the cold media gas of separated refrigerator oil between oil eliminator 5 and condenser 4 housings enters the heat exchanger tube arrangement space condenser 4, carries out condensing heat-exchange.
The cold media gas that completes Oil-gas Separation is condensed into after refrigerant liquid in the heat exchanger tube arrangement space of condenser 4, by feed pipe 9, by top, enter downward film evaporator 2, after absorbing therein the heat in refrigerating medium, be evaporated into cold media gas, by helical-lobe compressor 1, sucked and carry out volume compression, the compressed while, mix with the above-mentioned refrigerator oil that helical-lobe compressor 1 moving component is lubricated, mixture is discharged by helical-lobe compressor 1 exhaust outlet with vaporific form, enter air inlet pipe 6, complete whole refrigeration (heating) circulation.
The content that this description is not described in detail belongs to the known prior art of professional and technical personnel in the field.
