Abstract
The utility model discloses a distributed oil returning apparatus of a multi-united air-conditioning set with a heat recovering function. The distributed oil returning apparatus comprises a first distributor and a second distributor; an air suction pipe connected with an oil inlet pipe is vertically arranged; lubricating oil separated from an oil separator can not only be much evenly distributed to a plurality of compressors and accomplish an optimal lubricating effect, but the lubricating oil can flow back to the second distributor and then is transported to operating sets by the second distributor when some sets operate and some sets stop, so that lubricating oil waste is avoided and the optimal lubricating effect is achieved; work efficiency of the compressors is improved; energy is saved with low carbon emission; environment is therefore protected; and non-operating sets cannot be damaged, thereby prolonging overall service life of equipment.
Description
Technical field
The utility model belongs to air-conditioning technical field, specifically, relates to heat-recovery multi-connected air conditioning group distribute type oil return apparatus.
Background technology
Be provided with liquid-gas separator between the evaporimeter of air-conditioning and compressor, its effect is that the drop separation in medium is fallen, and to prevent drop from entering compressor, compressor is caused to damage.Existing air-conditioning liquid gas divides the operation principle of device to be: the medium that carries a small amount of drop enters in tank from medium inlet, and at the bottom of the liquid medium that density is high falls into tank and by the absorption of drying bag, low density gaseous medium floats on tank deck; Gaseous medium enters fairlead by funnel and then discharges from media outlet.
That refrigeration oil mainly plays a part in compressor is lubricated, sealing, cooling and energy adjustment, during the enforcement air-conditioning work, must refill refrigeration oil.Refrigeration oil is along with medium is extruded by compressor together, be deposited on the liquid-gas separator tank after circulation in air-conditioning system at the bottom of.The effect of oil return apparatus is to send the refrigeration oil at the bottom of the liquid-gas separator tank back to compressor.
Existing air-conditioning liquid-gas separator oil return apparatus, lubricating oil is general only directly inputs compressor by fairlead after filtering, for VRF Air Conditioning System, in part of generating units, turn round, in the situation that part of generating units is stopped transport, parts of lubricating oil enters in the stoppage in transit unit, not only lubricate not, also have infringement to unit itself.
Summary of the invention
The utility model has overcome shortcoming of the prior art, and heat-recovery multi-connected air conditioning group distribute type oil return apparatus is provided, and it has energy-saving and environmental protection, and efficiency is high, the characteristics that service life of equipment is long.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
Heat-recovery multi-connected air conditioning group distribute type oil return apparatus, comprise oil eliminator, distributor and at least two compressors, oil eliminator connects the first distributor by petroleum pipeline, also be provided with filter on petroleum pipeline between oil eliminator and the first distributor, each compressor connects an air intake duct, and air intake duct vertically arranges, the air intake duct middle part connects oil inlet pipe, oil inlet pipe all connects the first distributor, and the air intake duct bottom also connects the second distributor, and the second distributor connects an air inlet pipe.
Further, oil inlet pipe is for being horizontally disposed with.
Further, air intake duct vertically arranges.
Further, petroleum pipeline connects the first dispenser bottom.
Further, air inlet pipe connects the second dispenser bottom.
Compared with prior art, the beneficial effects of the utility model are:
Heat-recovery multi-connected air conditioning group distribute type oil return apparatus described in the utility model, owing to having adopted the first distributor and the second distributor, and the air intake duct be connected with oil inlet pipe vertically arranges, not only from oil separating device, lubricating oil out can be assigned to a plurality of compressors comparatively uniformly, make lubricating oil bring into play best effect, and turn round in part of generating units, in the situation that part is stopped transport, can make lubricating oil reflux and enter the second distributor, by the second distributor, lubricating oil is transported in the running unit again, can not cause the waste of lubricating oil, the maximum efficiency of performance lubricating oil, improve compressor and make altogether efficiency, save the energy, low-carbon environment-friendly, and do not damage the stoppage in transit unit, make Whole Equipment extend service life.
