Abstract

A nonreversible cycling compression refrigerator, is between the condensator and the expansion valve for filtration, separation and storage of the cooling medium in the cooling medium loop. The cylinder body has three parts that are the filterable cavity, the separate cavity and the reservoir cavity from top to bottom in turn, between the separate cavity and the reservoir cavities is clapboard and connect by the cooling medium pipe, in the separate cavity set return tube for discharge the oil from the cylinder body, the top cylinder body wall of the filterable cavity is set the intake tube, the bottom of the reservoir cavity is set the liquid cooling medium efferent. The invention, improve the work efficiency greatly, separate the oil and the cooling medium absolutely and guarantee the non-gaseous cooling medium to enter the expansion valve.

Description

Be used to filter, separate, store the device of refrigerant in the refrigerant loop

Technical field

The present invention relates to a kind of compression refrigeration machine of on-reversible cycle, specifically relate to be in a kind of refrigerant loop being used between condenser and the expansion valve to filter, separate, store the device of refrigerant.

Background technology

Existing domestic air conditioning, air conditioning for automobiles, coolant reclaiming machine and Teat pump boiler, the refrigerant that flows out from the condenser low-temperature end is between the expansion valve all being storage with the separating of three device realizations filtration, oil and refrigerants, refrigerant, they are respectively filter, separator and fluid reservoir, this structure has increased the volume of compressibility, the cost height is installed slow.

Summary of the invention

Therefore, the object of the present invention is to provide being used to that cost is low, installation rate is fast to filter, separate, store the device of refrigerant.

The object of the present invention is achieved like this.

The device that is used to filter, separate, store refrigerant in a kind of refrigerant loop, comprise cylinder body, described inner chamber of cylinder block is divided into three parts at least along its short transverse, be followed successively by filter chamber, disengagement chamber and reservoir compartment from top to bottom, be provided with dividing plate between disengagement chamber and the reservoir compartment, be provided with the oil return pipe of oil being discharged cylinder body in the disengagement chamber, be communicated with by the refrigerant pipe between disengagement chamber and the reservoir compartment, the cylinder wall that is positioned at the filter chamber top is provided with air inlet pipe, and the reservoir compartment bottom is provided with the liquid refrigerants efferent duct.

Above-mentioned purpose also can be done further perfect by the following technical programs.

The entrance point of described liquid refrigerants efferent duct is located at reservoir compartment bottom, and its port of export passes cylinder body from the cylinder body bottom surface, and perhaps its port of export extends upwardly along inner chamber of cylinder block and passes reservoir compartment, disengagement chamber and filter chamber successively and pass cylinder body from the cylinder body top.

The outlet side of described air inlet pipe is arcuation, and outlet bends towards side or top.

The entrance point of described refrigerant pipe is positioned at the middle and upper part of disengagement chamber, and its entrance point and the port of export are all curved, and import bends towards side or below, and outlet bends towards side or top.

The import of described oil return pipe is located on the dividing plate.

Structural design advantages of simple of the present invention, and filter, divide oil and be stored in one, adult is low, and installation is fast, has improved work efficiency greatly, and oil separates thoroughly with refrigerant, also to guarantee that the refrigerant that does not have gaseous state enters expansion valve.

Description of drawings

Fig. 1 is the axial section schematic diagram of embodiment 1;

Fig. 2 is the axial section schematic diagram of embodiment 2.

The specific embodiment

The invention will be further described below in conjunction with drawings and Examples.

Embodiment 1, in conjunction with Fig. 1, the device that is used to filter, separate, store refrigerant in a kind of refrigerant loop, comprise cylinder body 1, described cylinder body 1 inner chamber is divided into three parts along its short transverse, is followed successively by filter chamber 2, disengagement chamber 3 and reservoir compartment 4 from top to bottom, be provided with dividing plate 5 between disengagement chamber 2 and the reservoir compartment 3, dividing plate 5 is provided with outage 6, is connected to oil exit pipe 7 on the outage 6, and oil exit pipe 7 passes liquid storage cylinder 4 and links to each other with the low-pressure end of compressor.Be communicated with by refrigerant pipe 8 between disengagement chamber 3 and the reservoir compartment 4, the entrance point of refrigerant pipe 8 is positioned at the middle and upper part of disengagement chamber 3, its entrance point and the port of export are all curved, import bends towards the side or the below avoids oil to enter refrigerant pipe 8, outlet bends towards side or top, prevents that the refrigerant of gaseous state from entering expansion valve.

Enter cylinder body 1 inner chamber from the oil of condenser low-pressure end discharge and the mixture of refrigerant by cylinder body 1 top air inlet pipe 9, the outlet side of air inlet pipe 9 is arcuation, and outlet bends towards side or top, increases the time of volume of mixture diffusion, and the protection filter course is not destroyed.Reservoir compartment 4 bottoms are provided with liquid refrigerants efferent duct 10, the entrance point of liquid refrigerants efferent duct 10 is positioned at reservoir compartment 4 bottoms, and its port of export extends upwardly along cylinder body 1 inner chamber and passes reservoir compartment 4, disengagement chamber 3 and filter chamber 2 successively and pass cylinder body 1 from cylinder body 1 top and be connected with expansion valve.

Embodiment 2, and in conjunction with Fig. 2, embodiment 2 is that with the difference part of embodiment 1 port of export of described liquid refrigerants efferent duct 10 directly passes cylinder body 1 from cylinder body 1 bottom surface and is connected with expansion valve.
