Description
Technical field
The utility model relates to the air-conditioning system field, relates in particular to a kind of oil eliminator for the VRV air-conditioning system.
Background technology
The VRV air-conditioning system refers to the runoff of intermediary when chilling multi-gang air conditioner, present VRV air-conditioning system forms more complicated, and maximum has four outer machines multi-joint, for traditional VRV air-conditioning system, if oil equalizing pipe is not set, then when the multimode in the air-conditioning system connects, compressor oil will be in the modules random distribution, might a certain outer oil level seldom, and an other outer oil level is too much, so probably causes oily few outer machine because of oil starvation and so that compressor damage; If oil equalizing pipe is set, realize all oil control, because the oil equalizing pipe of prior art all is directly installed on each outer machine compressor, so need externally to install, and because distant between outside each compressor, so oil equalizing pipe is just long, to install not to be very convenient so on the one hand, because oil equalizing pipe is all to be connected with the compressor of every outer machine on the other hand, and again because oil equalizing pipe is longer, so the cycle of the compressor oil drainage-oil suction of every outer machine is longer, so that the unfailing performance of compressor operation reduces greatly.
Summary of the invention
Technical problem to be solved in the utility model is: an oil eliminator that is used for the VRV air-conditioning system with equal oil effect is provided, adopts above oil eliminator can effectively solve oil equalizing pipe shortcoming inconvenient and that outer machine compressor oil drainage-oil suction cycle is long is installed.
The technical scheme that the utility model adopts is: a kind of oil eliminator for the VRV air-conditioning system, it comprises housing, be arranged on the oil content inlet pipe that case top is used for importing refrigerant and oil, being arranged on case top goes out pipe and is arranged on the oily collecting pipe that housing bottom is used for oil is led back compressor for the oil content of deriving refrigerant, it comprises that also is used for the oil equalizing pipe that the oil that housing bottom is unnecessary imports to other modules of air-conditioning system, described oil equalizing pipe one end is connected with the housing side and communicates, the described oil equalizing pipe other end and oil content go out pipe and are connected and communicate, and the horizontal level of described oil equalizing pipe and housing side connectivity part is lower than the horizontal level that oil content goes out to manage the bottom.
Adopt above structure compared with prior art, the utlity model has following advantage: because oil eliminator is communicated with compressor, at original oil eliminator an oil equalizing pipe is set, like this when the oil mass of petroleum crude separator bottom is excessive, be when oil mass is too much in the compressor, the horizontal level of the oil mass in the housing can surpass the connectivity part of oil equalizing pipe and housing side, more greatly cause dynamic pressure higher static pressure lower because oil content goes out the refrigerant flowing velocity of pipe the inside this moment, be that the static pressure of oil equalizing pipe and housing connectivity part is greater than the static pressure that oil equalizing pipe and oil content go out to manage connectivity part, so can importing to oil content by oil equalizing pipe, unnecessary oil goes out pipe, for what restriction of oil mass, we can calculate according to the oil return service performance of the operation characteristic of compressor and air-conditioning system, the alternate position spike that namely only needs to calculate oil equalizing pipe and housing side connectivity part and housing bottom just, as long as other modules of air-conditioning system are in operation, will in sucking back the process of refrigerant, unnecessary oil mass be sucked, realize the balance of the outdoor machine oil of operation, and the utility model is simple in structure, only need to increase an oil equalizing pipe on the basis of original oil eliminator, install more convenient, and because all be in charge of and be arranged on the oil eliminator, do not need by all being in charge of a plurality of compressors to be connected, so external machine compressor oil drainage-oil suction cycle impact is little.
As preferably, also be provided with a magnetic valve that is used for control oil equalizing pipe break-make on the described oil equalizing pipe.Like this when air-conditioning system only has the single module operation, namely only has an outer machine when operation, because the air-conditioning system refrigerant flow rate is lower, the possibility that exists oil not flow back to, so the user just can cut off oil equalizing pipe by magnetic valve this moment, namely cut off oil equalizing circuit, guaranteed the air-conditioning system reliability of operation.
Description of drawings
Fig. 1 is the structure diagram that the utility model is used for the oil eliminator of VRV air-conditioning system.
As shown in the figure: 1, housing; 2, oil content inlet pipe; 3, oil content goes out pipe; 4, oily collecting pipe; 5, oil equalizing pipe; 6, magnetic valve.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment the utility model is described further, but the utility model is not limited only to the following specific embodiment.
As shown in the figure: a kind of oil eliminator for the VRV air-conditioning system, it comprises housing 1, be arranged on the oil content inlet pipe 2 that housing 1 top is used for importing refrigerant and oil, being arranged on housing 1 top goes out pipe 3 and is arranged on the oily collecting pipe 4 that housing 1 bottom is used for oil is led back compressor for the oil content of deriving refrigerant, it also comprises an oil equalizing pipe 5 that is used for the unnecessary oil in housing 1 bottom is imported to other modules of air-conditioning system, described oil equalizing pipe 5 one ends are connected with housing 1 side and both communicate, described oil equalizing pipe 5 other ends and oil content go out that pipe 3 is connected and both communicate, and the horizontal level of described oil equalizing pipe 5 and housing 1 side connectivity part is lower than the horizontal level that oil content goes out to manage 3 bottoms.
Also be provided with a magnetic valve 6 that is used for control oil equalizing pipe 5 break-makes on the described oil equalizing pipe 5.
Operation principle of the present utility model is: oil eliminator is that refrigerant is separated with oil, at first refrigerant enters from oil content inlet pipe 2 with the mist of oil, carry out screw at a high speed, then cold media gas can go out pipe 3 from oil content and goes out, oil is then stayed in the housing 1 because collision becomes oil droplet, the unnecessary compressor of the oil mass needed freezing oil mass Q0 under most evil bad condition that stores when housing 1 like this, the level height of housing 1 inner fluid will be higher than oil equalizing pipe 5 and 1 face connectivity part of housing like this, it is thinner to go out pipe 3 because of oil content again, so so the refrigerant flow rate that oil content goes out in the pipe 3 causes the high static pressure of dynamic pressure low greatly, so that oil equalizing pipe 5 and oil content go out the static pressure that the static pressure of pipe 3 connectivity parts is less than the connectivity part of oil equalizing pipe 5 and housing 1 side, the unnecessary oil mass in oil eliminator the inside just will be discharged to oil content by oil equalizing pipe 5 and go out in the pipe 3 like this, and then go out pipe 3 through oil content and be discharged in other modules of air-conditioning system, reached the oily balance of outer machine.And when only having an outer machine in operation, namely only have a compressor when operation, so need to all not have between multiple compressors, this moment, we can pass through the solenoid valve shuts oil equalizing pipe, can effectively guarantee like this reliability of compressor operating.
