Referring to fig. 1 and 2 in combination, according to an embodiment of the present invention, there is provided a dispenser, in which a dispenser 2 is disposed around a storage device, and the dispenser 2 is laterally charged with air and delivers a refrigerant to the storage device through a lateral air outlet.

It should be noted that, in this embodiment, the storage device is the compressor 1, and during the operation of the compressor 1, the refrigerant in the liquid separator 2 is sucked in, and in other embodiments, the storage device may also be a heat exchanger, a gas storage tank or a liquid storage tank.

The conventional liquid separator 2 is vertically arranged and arranged at the side of the compressor 1 through a bracket, so that the gravity center of the compressor 1 is deviated towards the air suction port of the compressor 1, and the vibration amplitude is large. According to the invention, the arrangement mode of the liquid separator 2 is changed, the liquid separator 2 is arranged around the center of gravity of the compressor 1, the vibration amplitude of the compressor 1 is reduced, and the unstable center of gravity caused by the inclination of the compressor 1 is avoided, so that abnormal complaints caused by system noise are reduced.

Because the knockout 2 is under the condition that the superheat degree of breathing in is low, the phenomenon of taking liquid of breathing in extremely easily appears, the inner chamber and the storage device intercommunication of knockout 2 after the installation, storage device's casing can produce the heat, and heat transfer makes the liquid refrigerant in the knockout 2 can evaporate rapidly to the inner chamber of knockout 2, reduces the emergence of taking liquid condition of breathing in. Specifically, during operation of the compressor 1, heat is generated by the casing of the compressor 1.

Referring to fig. 3, the dispenser 2 is horizontally arranged, one end of the dispenser 2 is provided with an air inlet pipe 201, the other end of the dispenser 2 is communicated with a storage device through an air suction pipe 4, and the refrigerant in the dispenser 2 flows in a circular path around the storage device.

In this embodiment, the horizontal arrangement of the liquid separator 2 changes the conventional vertical arrangement mode, when the air inlet pipe 201 sucks the refrigerant, the refrigerant can bypass the storage device to flow to the air suction pipe 4 because the air outlet end of the air inlet pipe 201 faces the storage device, and the flow mode lengthens the flow path of the refrigerant, so that the liquid refrigerant can be fully exerted, and the suction liquid of the refrigerant is further reduced.

A filter screen 5 is arranged at the joint of the air suction pipe 4 and the liquid separator 2.

As a specific embodiment, a second boss 204 is provided on the other side of the liquid separator 2 opposite to the first boss 203, the air suction pipe 4 is connected to the second boss 204, and a filter screen is provided at the air inlet of the second boss 204, so that the refrigerant can be filtered.

The dispenser 2 has an intake pipe 201, and an expansion valve 3 is provided in the intake pipe 201, and the expansion valve 3 adjusts the opening degree according to the current of the storage device to adjust the flow rate of the refrigerant flowing into the dispenser 2.

In this embodiment, when the storage device is the compressor 1, because the operation conditions of the compressor 1 are different, the required air intake amount is different, when the compressor 1 is operated in a high-frequency condition, the output current is large, the opening of the expansion valve 3 is adjusted to be maximum, the air intake amount in the air inlet pipe 201 is also large, and a large amount of refrigerant enters the liquid separator 2 to perform gas-liquid separation, so as to meet the requirement of the compressor 1 for large air intake amount; conversely, when the compressor 1 is operated at a low frequency, the opening degree of the expansion valve 3 is adjusted to the minimum. According to the expansion valve 3 disclosed by the invention, the opening degree of the expansion valve is regulated according to the current conditions of the compressor 1 under different working conditions, so that the volume of the inner cavity of the liquid separator 2 is changed, the variable capacity of the liquid separator 2 is realized, the energy efficiency of the compressor 1 is optimized under each working condition, and the energy efficiency of the whole system is further improved.

When the compression is performed, namely, different working conditions are performed, the operating frequency of the compressor 1 is also different, and the controller obtains the current condition of the compressor 1 and adjusts the opening of the expansion valve 3 according to the current signal. Specifically, if the compressor 1 is operated under the high-frequency refrigeration working condition with large air suction amount, the current output by the compressor 1 is large, and the opening of the expansion valve 3 is adjusted to be maximum, so that the air suction amount of the liquid separator 2 is increased, and the energy efficiency of the compressor 1 is improved; on the contrary, when the compressor 1 is operated at low frequency, the current output by the compressor 1 is small, the opening degree of the expansion valve 3 is reduced, the refrigerant supply amount is further reduced, the suction pulsation can be reduced, and the power consumption of the compressor 1 is further reduced.

In this embodiment, the controller is preferably a main control system of the air conditioning system, and the controller may be separately provided for control.
