The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
First embodiment
Referring to Fig. 1-Fig. 2 and Fig. 4, this air-conditioner, comprise the outdoor heat exchanger 1, cross valve 2, compressor 3, indoor heat exchanger 4 and the throttling arrangement 5 that connect routinely, throttling arrangement 5 is serially connected on the refrigerant pipeline between outdoor heat exchanger 1 and the indoor heat exchanger 4, is provided with two gears that above flow varies in size that switch according to the different circulation patterns of compressor 3 and running frequency and outdoor environment temperature in the throttling arrangement 5.Air-conditioner also comprises compressor control loop that compressor 3 running frequencies are provided and the temperature sensor that detects outdoor environment temperature, and throttling arrangement 5 also comprises the controller of regulating gear.
One end of first slide block 7 and first spring 11 joins, and the inwall of the other end of first spring 11 and first cavity joins, and the side of first valve body 6 is provided with the flow of flow-rate ratio second aperture 10 of first slide block, 7 corresponding first coil, 12, the first apertures 9 little.
First coil 12 in the present embodiment places the outside of first valve body 6 and over against first slide block 7; The design internal diameter of first aperture 9 is less, and design discharge is equivalent to the flow that specification capillaceous is internal diameter Φ 1.5*1000mm; The design internal diameter of second aperture 10 is big slightly, and design discharge is equivalent to the flow that specification capillaceous is internal diameter Φ 1.5*600mm.
Spacing between first aperture 9 and second aperture 10 that is to say that less than the width of first slide block 7 first slide block 7 only can seal one of them in first aperture 9 and second aperture 10 in sliding process, and can not seal two simultaneously.
When controller was not given 12 energisings of first coil, under the thrust of first spring 11, first slide block 7 slided to left side as shown in Figure 2, so, first aperture 9 is sealed by first slide block 7,10 conductings of second aperture, and the flow of the air-conditioning system of this moment is the flow of second aperture 10.
When controller is given 12 energisings of first coil, because the magnetic force of first coil 12 is greater than the thrust of first spring 11, then first slide block 7 slides to right side as shown in Figure 2 under the effect of magnetic force, so, second aperture 10 is sealed by first slide block, 9 conductings of first aperture, this moment, the flow of air-conditioning system was the flow of first aperture 9.So just realized that throttling arrangement 5 has two retaining different flows.
The refrigeration frequency F1 and the temperature value T1 of default compressor 3 in the kind of refrigeration cycle of air-conditioner, what heat in the circulation default compressor 3 heats frequency F2 and temperature value T2, refrigeration frequency F1 is 4～130Hz with the span that heats frequency F2, and the span of temperature value T1 and temperature value T2 is-20～60 ℃.
When air-conditioner moves, comprise the steps:
The first step, detect the operational mode of air-conditioner, the running frequency f and the outdoor environment temperature t of compressor 3: if be kind of refrigeration cycle, then entered for second step, if, then entered for the 5th step for heating circulation,
Second step, relatively running frequency f and refrigeration frequency F1 and outdoor environment temperature t and temperature value T1: if running frequency f 〉=refrigeration frequency F1, no matter the relation of outdoor environment temperature t and temperature value T1 how, would all have entered for the 3rd step; If when running frequency f＜refrigeration frequency F1, and outdoor environment temperature t 〉=temperature value T1, entered for the 3rd step; If when running frequency f＜refrigeration frequency F1, and outdoor environment temperature t＜temperature value T1, entered for the 4th step,
The 3rd step, select the big gear of flow to carry out conducting by controller,
The 4th step, select the little gear of flow to carry out conducting by controller,
As running frequency f 〉=refrigeration frequency F1, during and outdoor environment temperature t 〉=temperature value T1, too not high in order to guarantee air-conditioning system pressure because compressor frequency and outdoor environment temperature are higher, the choke valve of controller control is at this moment selected the first bigger retaining of flow.
As running frequency f＜refrigeration frequency F1, and during outdoor environment temperature t＜temperature value T1, in order to guarantee that air-conditioning system has certain degree of superheat, prevent the generation of compressor liquid hit phenomenon, simultaneously in order to improve the Energy Efficiency Ratio of air-conditioner when the low-frequency operation, the choke valve of controller control is at this moment selected the second less retaining of flow.
The 5th step, relatively running frequency f and heat frequency F2 and outdoor environment temperature t and temperature value T2: if running frequency f 〉=heat frequency F2 during and outdoor environment temperature t 〉=temperature value T2, entered for the 6th step; If when running frequency f 〉=heat frequency F2, and outdoor environment temperature t＜temperature value T2, entered for the 7th step; If running frequency f＜heat frequency F2, no matter the relation of outdoor environment temperature t and temperature value T2 how, all entered for the 7th step,
The 6th step, select the big gear of flow to carry out conducting by controller,
In the 7th step, select the little gear of flow to carry out conducting by controller.
As running frequency f＜heat frequency F2, and during outdoor environment temperature t＜temperature value T2, in order to guarantee that air-conditioning system has certain degree of superheat, prevent the generation of compressor liquid hit phenomenon, simultaneously in order to improve the Energy Efficiency Ratio of air-conditioner when the low-frequency operation, the choke valve of controller control is at this moment selected the second less retaining of flow.
Second embodiment
Referring to Fig. 1, Fig. 3 and Fig. 4, throttling arrangement 5 comprises second valve body 16 with second cavity, second valve body 16 is provided with second import 16.1 and second outlet 16.2 that communicates with second cavity, be provided with second slide block 17 that changes second valve body, 16 flows in second cavity, be provided with first on the sliding stroke that is positioned at second slide block 17 spacing 16.3 and second spacing 16.4 in second cavity, projection 17.1 on second slide block 17 or second slide block 17 is between first spacing 16.3 and second spacing 16.4, tapered or the wedge shape in the end of second slide block 17, the end of second slide block 17 is positioned at the joint of second import 16.1 or second outlet, 16.2 and second inner chamber, one end of second slide block 17 and second spring 21 joins, the inwall of the other end of second spring 21 and second cavity joins, and the side of second valve body 16 is provided with and second slide block, 17 corresponding second coils 22.First spacing 16.3 is positioned at second spacing 16.4 top.
When controller is not given 22 energisings of second coil, then under the thrust of second spring 21, second slide block upwards slides to first spacing 16.3 places of second valve body 16, because the end of taper this moment and and the annular circulation area that forms of the inwall of second import 16.1 less, so the flow of air-conditioning system is less.
When controller is given 22 energisings of second coil, because the magnetic force of second coil 22 is greater than the thrust of second spring 21, then second slide block 17 slides to second spacing 16.4 places of second valve body 16 downwards under the effect of magnetic force, because the annular circulation area that the inwall of end second import 16.1 of taper this moment forms is bigger, so the air-conditioning system flow is bigger.Realize that so throttling arrangement 5 has two retaining different flows.
All the other are not stated part and see first embodiment, no longer repeat.
More than be preferred implementation of the present utility model, should be pointed out that above-mentioned preferred implementation should not be considered as restriction of the present utility model, protection domain of the present utility model should be as the criterion with claim institute restricted portion.
