Description
Technical Field
The utility model relates to a refrigeration plant field, and in particular to outlet duct structure and multi-cylinder compressor reservoir of multi-cylinder compressor reservoir.
Background
The compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas, and is the heart of a refrigeration system. The refrigerating cycle is powered by sucking low-temperature and low-pressure refrigerant gas from the air suction pipe, driving the piston to compress the refrigerant gas through the operation of the motor, and discharging high-temperature and high-pressure refrigerant gas to the exhaust pipe. A rolling rotor type compressor is a type of a commonly used compressor, which uses a change in displacement volume caused by rotation of an eccentric cylindrical rotor (called a rolling rotor or a rolling piston) within a cylindrical cylinder to achieve compression of refrigerant gas. The compressor mainly comprises a totally-enclosed rolling rotor (namely a cylinder, also called a pump body), a driving motor and a closed shell, and is widely applied to refrigeration systems such as refrigerators, household air conditioners, cold storages and the like.
The traditional rolling rotor type compressor is a single-cylinder rolling rotor type refrigeration compressor, and the problem of unbalanced inertia force exists in the rotation of a single rotor. Compressors having a plurality of cylinders have been developed to solve this problem. The existing multi-cylinder compressor mainly comprises a double-cylinder compressor, a double-cylinder variable-capacity compressor, a double-cylinder two-stage compressor, a three-cylinder two-stage compressor and a three-cylinder two-stage variable-capacity compressor. Two cylinders which are connected in parallel and are symmetrically arranged with a phase difference of 180 degrees are arranged in the double-cylinder compressor, the double-cylinder variable-capacity compressor, the three-cylinder two-stage compressor and the three-cylinder two-stage variable-capacity compressor. The two cylinders are in 180 DEG phase difference when working, and the load torque is changed by 180 DEG, so the load torque of the compressor is changed smoothly. Under the condition that the volume and the structure of the two parallel cylinders are the same, the variation amplitude of the load torque and the level of the vibration of the whole machine are far lower than those of a single-cylinder rolling rotor type refrigeration compressor, so that the two parallel cylinders can operate in a wider frequency range.
In a multi-cylinder compressor with two parallel cylinders, two intake pipes are required, and two corresponding outlet pipes are provided in a reservoir connected to the intake pipes. Fig. 1 shows the structure of a prior art reservoir adapted to this type of multi-cylinder compressor, where the output ends of two air outlet pipes 10_1 at the bottom of the reservoir are connected to two air suction pipes of the compressor, respectively, and the input ends are connected to two air ducts 10_2 in the reservoir housing. In the reservoir body, two air ducts 10_2 are symmetrically arranged on two sides of the air inlet pipeline 10_3 respectively, and the air flow entering the reservoir shell from the inlet pipeline 10_3 can continuously wash the inner wall of the reservoir and the outer walls of the two air ducts 10_2 except the two air ducts, so that the influence on noise is very large. In addition, in the structure of fig. 1, the distance between the two outlet pipes 10_1 is very short, and when the two outlet pipes are welded to the reservoir casing, the welding is difficult and the leakage rate of the welding is high because the distance is too short.

Detailed Description
In a multi-cylinder compressor with two parallel cylinders, in order to make both parallel cylinders work, the multi-cylinder compressor needs to be equipped with two air suction pipes, and fig. 1 is a schematic structural diagram of a reservoir with double air guide pipes matched with the multi-cylinder compressor in the prior art. In the structure, the two air ducts are symmetrically distributed by taking the central line of the shell of the liquid storage device as an axis. The gas entering from the air inlet pipeline of the liquid storage device is divided into two gas guide pipes. In the shunting process, the air flow can wash the inner wall of the shell of the liquid storage device and the outer walls of the two air guide pipes, so that the noise in the liquid storage device is large. In order to solve the problem, the applicant proposes to replace two air ducts in the prior art with one air duct, and the air entering from the air inlet pipeline of the liquid reservoir directly enters into one air duct, so as to solve the problem of high noise. However, in order to match with two air suction pipes in a multi-cylinder compressor, the air outlet end of the air guide pipe is necessarily provided with a shunting type air outlet pipe structure. However, the size of the bypass outlet pipe structure is difficult to be compatible with, due to the installation space between the multi-cylinder compressor and the accumulator in the existing compressor system.
In view of this, this embodiment provides an outlet duct structure of multi-cylinder compressor reservoir, and the outlet duct of this structure can well solve the problem of installation space between the reservoir of single air duct and the multi-cylinder compressor.
