To ensure that equipment safety is efficiently run.According to reducing air velocity and changing point oily principle of airflow direction, make high steam
In elaioleucite separated under the effect of gravity.General air velocity is in below 1m/s, so that it may which contained diameter in steam exists
The elaioleucite of more than 0.2mm is separated.Usually used oil eliminator has four kinds of washing type, centrifugal, material filling type and filtering type.
Domestic each carbon dioxide heat-pump producer now uses low pressure circuit.Carbon dioxide refrigerating system is such as returned using low pressure
Oil has the disadvantage that：
1st, it is of high cost：High-pressure solenoid valve, heating wire need to be used；Oiling compressor amount need to be increased;
2nd, high failure rate：High failure rate main cause is frequent solenoid valve break-make, heating wire long-time and lower temperature copper
Pipe contacts.Low circumstance temperature runtime system inside cold oil viscosity increase causes throttle system flow to diminish；Refrigeration compressor air suction
Amount diminishes.
3rd, energy consumption is big：For lifting oil temperature electrical heating heating need to be used to ensure oil temperature during low circumstance temperature operation；Compressor and freeze oil
Circulation reduces heat exchanger heat exchange efficiency in whole system（COP）.
Utility model content

Repair, material adult, the carbon dioxide heat-pump high efficient oil subsystem for lifting CO 2 trans-critical heat pump heat exchanger heat exchange efficiency.
To achieve the above object, technical solution is used by the utility model：Carbon dioxide heat-pump high efficient oil subsystem,
Including：Shell, it is characterised in that：Oil return opening is equipped with the bottom of the shell, the top of shell is equipped with gas outlet；Described
Shell inner cavity in, be equipped with level-one oil and two level oil successively from lower to upper, the level-one oil is fixedly mounted on outer
Shell bottom, its position is corresponding with oil return opening, and two level oil is fixedly mounted on cover top portion, its position is corresponding with gas outlet；
Described level-one oil one end is connected with air inlet, which puts in housing outward end through shell waist from inside to outside.
Preferably, the primary oil is divided into a point oil sheet.
Preferably, the two level oil is to divide oil network.
Preferably, capillary brass pipe is connected with the oil return opening, filtering has been sequentially connected in series in the capillary brass pipe
Device and flow control valve.
Preferably, the filter is filter screen, 80 mesh of the filter screen/inch.
Preferably, the shell is the high pressure resistant housing of capsule shape, which is made using SU304 seamless pipes.
Preferably, the oil return opening, gas outlet and air inlet are made using 2.5mm304 stainless steel tubes.
Beneficial effect
The utility model improves machine by using the structure type being built in a point oil network, point oil sheet in storage of higher pressures filling
The stability of group, reduce maintenance difficulty, and the utility model has the following advantages compared with prior art：1st, whole oil system without
Need to power；2nd, oil temperature will not cross bottom, without heating；3rd, from the direct oil return in compressor air-discharging end, improved without heat exchanger
Heat exchange efficiency（COP）；4th, need not increase injection flow；5th, system filtering function is added；6th, can flexible modulation oil return as needed
Amount.The utility model is simple in structure, and mounting and adjusting is easy, improves set steady, reduces maintenance, material adult, lifted across facing
Boundary's carbon dioxide heat-pump heat exchanger heat exchange efficiency.
