3, summary of the invention:
The purpose of this utility model is to consider the problems referred to above and provides operational factors such as a kind of delivery temperature value that makes each module inner compressor and force value to keep consistency in the reasonable scope, guarantees the multimode multi-online air-conditioning system off-premises station of complete machine stable performance.
Structural representation of the present utility model as shown in Figure 1, include some off-premises station modular units of forming by low-pressure liquid storing tank (1), compressor (5), cross valve (6), outdoor heat exchanger (7), high pressure fluid reservoir (9), each off-premises station modular unit is connected in parallel, and be connected with indoor set by liquid pipe (13) and tracheae (12), wherein the low-pressure liquid storing tank (1) in each off-premises station modular unit connects by refrigerant balance pipe (4).
Above-mentioned refrigerant balance pipe (4) is connected the medium position of low-pressure liquid storing tank (1) side.
Above-mentioned refrigerant balance pipe (4) is a copper pipe.
Low-pressure liquid storing tank (1) in above-mentioned each off-premises station modular unit with pipeline that refrigerant balance pipe (4) is connected on be equiped with stop valve (14) respectively.
Above-mentioned off-premises station modular unit includes two or three, and the model of each modular unit can be the same, also can be different model.
Above-mentioned off-premises station modular unit includes 1~5 compressor (5).
High pressure fluid reservoir (9) in above-mentioned each off-premises station modular unit is connected with liquid pipe (13) by stop valve (10), and the cross valve (6) in each off-premises station modular unit is connected with tracheae (12) by ball valve (11).
The utility model is owing to adopt a refrigerant balance pipe to connect the structure of the low-pressure liquid storing tank in the off-premises station modular unit, make and form a linker in all modules between the low-pressure liquid storing tank, balance by pressure realizes the balance that refrigerant distributes between the module, store in certain module low-pressure liquid storing tank in the less low-pressure liquid storing tank of too much refrigerant meeting automatic stream refrigerant, reach the equilibrium of coolant quantity between each module, operational factors such as the delivery temperature value of each module inner compressor and force value are kept consistency in the reasonable scope, guarantee the complete machine stable performance, thus the operation of the normal reliable of the system of assurance.The utility model cost is low, makes simple and conveniently, and mentality of designing is ingenious, and effect is obvious, is a kind of function admirable, convenient and practical multimode multi-online air-conditioning system off-premises station.
4, description of drawings:
Fig. 1 is a structural representation of the present utility model.
5, the specific embodiment:
Embodiment:
Structural representation of the present utility model as shown in Figure 1, include some off-premises station modular units of forming by low-pressure liquid storing tank 1, compressor 5, cross valve 6, outdoor heat exchanger 7, high pressure fluid reservoir 9, each off-premises station modular unit is connected in parallel, and be connected with indoor set by liquid pipe 13 and tracheae 12, wherein the low-pressure liquid storing tank in each off-premises station modular unit 1 connects by refrigerant balance pipe 4.In the present embodiment, above-mentioned refrigerant balance pipe 4 is connected the medium position of low-pressure liquid storing tank 1 side.Above-mentioned refrigerant balance pipe 4 is a copper pipe.In addition, also be provided with throttling arrangement 8 between outdoor heat exchanger 7 and the high pressure fluid reservoir 9.
Be convenient control, the low-pressure liquid storing tank 1 in above-mentioned each off-premises station modular unit with pipeline that refrigerant balance pipe 4 is connected on be equiped with stop valve 14 respectively.High pressure fluid reservoir 9 in above-mentioned each off-premises station modular unit is connected with liquid pipe 13 by stop valve 10, and the cross valve 6 in each off-premises station modular unit is connected with tracheae 12 by ball valve 11.
Above-mentioned off-premises station modular unit includes two or three, and the model of each modular unit can be the same, also can be different model.Above-mentioned off-premises station modular unit includes 1~5 compressor 5.In the present embodiment, above-mentioned off-premises station modular unit includes three, and the model of each modular unit is identical, and above-mentioned each off-premises station modular unit includes 3 compressors 5.
Following two kinds of situations can appear in the utility model when actual motion:
1) when interior machine demand load during less than certain value, has only one of them module in running, its pipeline of modular unit that does not have running this moment is by other devices " being blocked ", refrigerant flows to indoor set by the outdoor module unit of running by pipeline, and this modular unit is got back to by another root pipeline in throttling, evaporation back under the effect of pressure of inspiration(Pi).
2) when interior machine demand load reaches certain value, the more than modular unit of system is in running, there is not its pipeline of modular unit of running " to be blocked " by stop valve 10, refrigerant is discharged by the modular unit of running, flow to indoor set by same pipeline, the modular unit of running is got back in throttling, evaporation back under the effect of pressure of inspiration(Pi) by another root pipeline.
