Description

Integrated liquid storage gas-liquid separator suitable for automobile air conditioner

Technical Field

The invention relates to the field of automobiles, in particular to an integrated liquid storage gas-liquid separator suitable for an automobile air conditioner, and particularly relates to liquid storage and gas-liquid separator equipment of an automobile air conditioning system.

Background

In automotive air conditioning systems, an accumulator is typically mounted at a location between the condenser outlet and the throttle mechanism inlet. The liquid accumulator is mainly used for storing redundant refrigerant, removing redundant moisture, filtering impurities and separating gas from liquid so as to ensure that the flowing-out refrigerant is liquid. In some automotive air conditioning systems, a gas-liquid separator is used at a location between the evaporator outlet and the compressor inlet. The gas-liquid separator also has the functions of storing excess refrigerant, removing excess moisture, filtering impurities, and separating gas from liquid. However, unlike the accumulator, the refrigerant flowing out of the gas-liquid separator is in a gaseous state, and the purpose of the refrigerant is to ensure that gas enters the compressor, thereby preventing the liquid impact problem.

With the popularization of electric automobiles, particularly the application of heat pump air conditioning technology, part of automobile air conditioning systems simultaneously adopt a liquid accumulator and a gas-liquid separator to ensure the performance of the system in refrigeration in summer and heating in winter. For example, the heat pump air conditioning systems in utility model CN207481600U and invention CN103807936a all adopt the design of coexistence of liquid storage device and gas-liquid separator.

Compared with the traditional fuel oil automobile air conditioner, the heat pump air conditioning system of the electric automobile has the advantages that the mass difference of the refrigerant needed in the refrigerating state and the heating state is large, and the charging amount is generally selected to be a large value, so that the gas-liquid separator needs to be large in size, difficulty is caused to the arrangement of the air conditioning system, and in addition, the weight of the system is large. It is therefore of great importance to optimize the structural design of the liquid and gas-liquid separator, thereby reducing the overall volume and complexity of the arrangement.

Cn201820626356.X discloses an integrated energy-saving refrigeration auxiliary device and an air-conditioning refrigeration system thereof, but the patent still is a design of two cylinders by connecting two cylinders of a liquid accumulator and a gas-liquid separator together, and the patent cannot achieve the purposes of reducing the system structure and weight and reducing the number and cost of pipelines.

CN201920994682.0 discloses an automobile heat pump air conditioning system with a multifunctional liquid storage device, the multifunctional liquid storage device used in the invention adopts the design of 2 inlets and 4 outlets, and the cylinder body also comprises a built-in heat exchanger; however, the multifunctional liquid accumulator in the invention is not designed with a built-in ball valve mechanism, and the switching operation of the functions of the liquid accumulator and the gas-liquid separator cannot be realized.

Fig. 12, 13 and 14 depict partial installation or exploded views of the present invention.

The working principle of the invention is as follows:

when the device is installed in an automobile air conditioning system, refrigerant flows into the cylinder from the inlet 2, the refrigerant in the cylinder flows out through the internal exhaust pipe 6 and the outlet 3, and redundant refrigerant of the system is stored in the inner cavity of the cylinder 1. The internal inlet pipe 5 serves to introduce the gaseous refrigerant at the top inside the cylinder 1 to the internal outlet pipe 6 through the ball valve structure 4 and then to discharge it from the outlet 3. The main functions of the device are to separate gas and liquid of the flowing refrigerant, store the redundant refrigerant of the system, remove the redundant moisture of the system and filter the impurities of the system.

The device integrates the functions of a reservoir and a gas-liquid separator, and whether the device operates as a reservoir or a gas-liquid separator is controlled by the ball valve mechanism 4. When the apparatus is operated as an accumulator, liquid refrigerant flows out of the outlet 3, and when the apparatus is operated as a gas-liquid separator, gaseous refrigerant flows out of the outlet 3.

Fig. 8 illustrates the state and refrigerant flow lines when the integrated accumulator gas-liquid separator operates as an accumulator. At this time, the solid portion of the valve body 441 faces the third through hole of the first seal 422, so that the gas refrigerant at the top of the fluid accommodating chamber 11 is prevented from entering the internal gas exhaust pipe 6 from the internal gas inlet pipe 5 through the valve body main portion 421, the first seal 422 and the valve body 441. The third valve core hole 444 faces the second sealing member 423, so that the liquid refrigerant at the bottom of the fluid accommodating chamber 11 can pass through the second nut through hole 452 of the through hole nut structure 45 and then the first nut through hole 451 due to the pressure in the cylinder 1, and then sequentially pass through the second through hole 4231 of the second sealing member 423, the third valve core hole 444 of the valve core body 441, the first valve core hole 442 and the first flow through hole 425 of the valve body main portion 421 to enter the inner exhaust pipe 6, and finally flow out of the cylinder through the outlet 3. When the integrated liquid-gas-liquid separator operates as a liquid reservoir, the balance pipe 7 does not need to operate, and therefore the link structure 445 is in a position to cover the balance hole 61.

Fig. 9 illustrates the state and refrigerant flow lines when the integrated liquid storage gas-liquid separator operates as a gas-liquid separator. At this time, the valve core assembly 44 is driven by the motor mechanism 41 to rotate 90 degrees, so that the solid portion of the valve core body 441 faces the second through hole 4231 of the second sealing member 423, and thus the liquid refrigerant at the bottom of the fluid accommodating chamber 11 is prevented from entering the inner exhaust pipe 6 through the through hole nut structure 45, the second sealing member 423 and the valve core assembly 44. Meanwhile, the second spool hole 443 on the other side of the spool body 441 faces the third through hole in the first seal 422, so that the gas refrigerant at the top of the fluid receiving chamber 11 passes through the second through hole 426 and the third through hole 428 on the valve body main portion 421 from the internal intake pipe 5, passes through the third through hole 4221 on the first seal 422, the second spool hole 443 on the spool body 441, then passes through the first through hole 425 from the first spool hole 442 into the internal exhaust pipe 6, and finally flows out of the cylinder through the outlet 3. When the integrated liquid storage gas-liquid separator operates as a gas-liquid separator, the balance pipe 7 needs to operate, and at this time, the link structure 445 connected to the valve core body 441 is moved away from the position originally covering the balance hole 61 due to the rotation of the valve core assembly 44 to expose the balance hole, thereby realizing the normal operation of the balance pipe.

The invention provides an integrated liquid storage gas-liquid separator suitable for an automobile air conditioner, which utilizes a cylinder body to realize the functions of a liquid storage device and the gas-liquid separator at the same time, and provides a basic operation principle of the device, and realizes the switching between the functions of the liquid storage device and the gas-liquid separator through a ball valve mechanism integrated to the cylinder body. The invention only uses one cylinder to realize the functions of the liquid accumulator and the gas-liquid separator, so the volume and the weight of the system are obviously reduced, the number of corresponding pipelines is also reduced, and the complexity and the cost of the system arrangement are obviously reduced.
