The oil separator is arranged between the condenser and the compressor. A gas inlet of the oil separator is communicated with a refrigerating fluid outlet of the compressor. A gas outlet of the oil separator is communicated with a refrigerating fluid inlet of the condenser. A lubricating oil outlet of the oil separator is connected to a lubricating oil system of the compressor through a first oil returning pipeline which is provided with a valve. The falling film type water source heat pump is high in heat exchanging efficiency, reliable in operation, small in abrasion and long in service life.
Description
Technical field
The utility model relates to a kind of heat pump, relates to specifically a kind of falling film type water source heat pump units.
Background technology
The falling film type heat exchanger, because its coefficient of performance is high, refrigerant charge is few, oil return is reliable and stable, more and more is subject to everybody favor.The falling film type heat exchanger is more easily determined because version makes the oil return position, but people use the injection source of lubricating oil as oil return usually, the flow resistance of lubricating oil is large like this, the oil return effect of meeting remote-effects unit, compressor oil return efficiency is given a discount, cause compressor part wearing and tearing, affect complete machine service life.
The utility model content
The purpose of this utility model is to provide a kind of falling film type water source heat pump units, and its heat exchange efficiency is high, reliable, wearing and tearing are little, and extend service life.
To achieve these goals, technical solution of the present utility model is: a kind of falling film type water source heat pump units, comprise the compressor that is in turn connected to form closed-loop by pipeline, condenser, device for drying and filtering, evaporimeter, also comprise oil eliminator, oil eliminator is located between described condenser and compressor, the gas access of oil eliminator is communicated with the refrigerant outlet of described compressor, the gas vent of oil eliminator is communicated with the refrigerant inlet of described condenser, the lubricating oil outlet of oil eliminator is connected to the lubricating oil system of described compressor by the first return line, the first return line is provided with valve.
The utility model falling film type water source heat pump units, wherein, also comprise injector, the air inlet of injector is communicated with the outlet of the ejection gas of described oil eliminator, the inlet port of injector is communicated with the bottom oil return mouth of described evaporimeter by inlet line, the nozzle of injector is communicated with the lubricating oil system of described compressor by the second return line, is equipped with valve on described inlet line, the second return line.
The utility model falling film type water source heat pump units, wherein, described each valve is magnetic valve.
After adopting such scheme, the utility model falling film type water source heat pump units is owing between condenser and compressor, being provided with oil eliminator, therefore the lubricating oil separation in cold-producing medium out and by lubricating oil can be transported to compressor, not only make cold-producing medium keep higher heat exchange efficiency, and make compressor enough lubricating oil be arranged to remain on normal lubricating status, reliable, reduction wearing and tearing, increase the service life.
In addition, owing to also comprising injector, use gas as the injection source, because the flow resistance of gas is less than the flow resistance of lubricating oil, so guaranteed the flow velocity in injection source, can well the lubricating oil of base of evaporator be taken back to compressor, guarantee that further compressor remains on normal lubricating status.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model falling film type water source heat pump units.
The specific embodiment
As shown in Figure 1, the utility model falling film type water source heat pump units comprises the compressor 11 that is in turn connected to form closed-loop by pipeline, oil eliminator 19, condenser 13, device for drying and filtering 15 and evaporimeter 17, compression 11 is semiclosed monoblock type double-screw compressor, condenser 13 is shell and tube condenser, evaporimeter 17 is the package downward film evaporator, oil eliminator 19 is Horizontal oil separator, pipeline between device for drying and filtering 15 and evaporimeter 17 is provided with magnetic valve and flow controller 14, the gas access of oil eliminator 19 is communicated with the refrigerant outlet of compressor 11, the gas vent of oil eliminator 19 is communicated with the refrigerant inlet of condenser 13, the lubricating oil outlet of oil eliminator 19 is connected to the lubricating oil system of compressor 11 by the first return line 191, the first return line 191 is provided with magnetic valve.
Between oil eliminator 19, evaporimeter 17 and compressor 11, also be provided with injector 12, the air inlet of injector 12 is communicated with the ejection gas outlet of oil eliminator 19, the inlet port of injector 12 is communicated with the bottom oil return mouth of evaporimeter 17 by inlet line 171, the nozzle of injector 12 is communicated with the lubricating oil system of compressor 11 by the second return line 192, is equipped with magnetic valve on inlet line 171, the second return line 192.
Above-mentioned each magnetic valve also can adopt other valve bodies.
During the work of the utility model falling film type water source heat pump units, the high-temperature high-pressure refrigerant gas that compressor 11 is discharged, enter oil eliminator 19, in oil eliminator 19, the lubricating oil in high-temperature high-pressure refrigerant is separated, high-temperature high-pressure refrigerant gas after separation enters condenser 13, cold-producing medium and condensation side recirculated water generation heat exchange in condensation process, rise to the condensation side circulating water temperature temperature required, condensation of refrigerant becomes liquid simultaneously, drying filter 15 dryings, flow controller 14 reducing pressure by regulating flows, become the gas-liquid mixture of low-temp low-pressure, then enter evaporimeter 17 evaporations, in evaporimeter 17, low-temperature low-pressure refrigerant liquid evaporates from draw heat the evaporation side water source, simultaneously, evaporation side recirculated water is reduced to temperature required, form low-temp low-pressure gas, by compressor 11 suction ends, sucked again, start new round circulation, complete refrigeration or heat process, refrigeration and heat-production functions have switched by the water route of water source side and end side.Through oil eliminator 19, separate the lubricating oil obtained and flow back into compressor 11 through the first return line 191, and under the effect of injector 12, the refrigerant gas of the HTHP that oil eliminator 19 is interior is as the gas injection source, the refrigerant gas of HTHP enters injector 12, and the lubricating oil of evaporimeter 17 bottoms is brought back to compressor 11 through the second oil return pipe 192.
In the utility model falling film type water source heat pump units running, when the high oil level of unit is not reported to the police, magnetic valve on the first return line 191 and pipeline is open mode, the lubricating oil that oil eliminator 19 is separated is expelled back into compressor 11, magnetic valve on inlet line 171 and the second return line 192 is closed condition, if during the high warning of unit, above-mentioned magnetic valve is opened, now the ejecting scavenge return system is started working, and lubricating oil is expelled back into to compressor 11.
The above embodiment is described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineers and technicians in this area make the technical solution of the utility model, all should fall in the definite protection domain of claims of the present utility model.
