The specific embodiment
Need to prove, in the situation that do not conflict, embodiment and the feature among the embodiment among the application can make up mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.
Air-conditioner mode-changeover device in the present embodiment comprises the parts on a plurality of each pipelines that are installed in respectively air-conditioner, comprise liquid tube coupling stream device, low pressure gas pipe throttling arrangement and high-pressure air pipe throttling arrangement, these parts are connected with liquid pipe, low pressure gas pipe and high-pressure air pipe in the air-conditioner respectively, connected mode is: liquid tube coupling stream device is connected in the liquid pipe, the low pressure gas pipe throttling arrangement is in parallel with the low pressure gas pipe valve, and the high-pressure air pipe throttling arrangement is in parallel with the high-pressure air pipe valve.
A kind of concrete structure of the working mode of air-conditioner switching device shifter in the present embodiment as shown in Figure 2.Fig. 2 is according to the air-conditioner mode-changeover device schematic diagram in the embodiment of the invention.
In Fig. 2, the low pressure gas pipe throttling arrangement is comprised of valve 0 and capillary 12, the high-pressure air pipe throttling arrangement is comprised of valve 7 and capillary 5, liquid tube coupling stream device is electric expansion valve 9, in realization, low pressure gas pipe throttling arrangement, high-pressure air pipe throttling arrangement and liquid tube coupling stream device also can be the throttling arrangements of other structures.For example liquid tube coupling stream device can be valve and the capillary that is cascaded.Connecting indoor heat exchanger one side has respectively liquid pipe 10 and tracheae 11, and liquid pipe 10 is connected with liquid pipe 1 by liquid tube coupling stream device, and the afterwards in parallel and tracheae 11 of low pressure gas pipe 2 and high-pressure air pipe 3 is connected in series.
The course of work of the air-conditioner mode-changeover device in the present embodiment is described respectively below in conjunction with Fig. 3, Fig. 4.Air-conditioner mode-changeover device among Fig. 3 and Fig. 4 is positioned at dotted line frame 4, adopts structure shown in Figure 2, and valve 8 and valve 6 are respectively low pressure gas pipe valve and high-pressure air pipe valve.
Adopt the arrow on the pipeline to represent that the direction that has refrigerant to press arrow in the pipeline flows in Fig. 3 and Fig. 4, pipeline is that heavy line represents in this pipeline refrigerant is arranged, and pipeline is that fine line represents do not have refrigerant in this pipeline.
The inventor finds through research, and larger noise appears in existing air-conditioner in work-mode switching process mainly be because the parts of air-conditioner expand with heat and contract with cold and the variation of refrigerant pressure produces greatly in the refrigerant flow process.Therefore, utilize in the present embodiment throttling arrangement, air-conditioner switches to the process of the state of heating from refrigerating state, form intermediateness, thereby thereby avoid pipeline pressure and variations in temperature is too fast causes violent expanding with heat and contract with cold to reduce noise.The working mode of air-conditioner switching device shifter that utilizes the present embodiment to provide can be realized this intermediateness, is illustrated below in conjunction with Fig. 3 and Fig. 4.
Fig. 3 switches to the schematic diagram that heats air-conditioner state variation the mode of operation process according to the air-conditioner in the embodiment of the invention from the refrigeration work pattern.
As shown in Figure 3, air-conditioner passes through intermediateness 32, intermediateness 33 successively by refrigerating state 31, then reaches the state of heating 34.When air-conditioner was in refrigerating state 31, valve 6, valve 7 and valve 0 were closed condition, and valve 8 is opening, and electric expansion valve 9 is automatic adjustment state.If receive the instruction that switches to the state of heating, for example receive that indication air-conditioner that remote controller is sent switches to the remote information of the state of heating, then stop refrigerant and enter off-premises station by low pressure gas pipe from indoor set, so valve-off 8; And the throttling arrangement that makes refrigerant process high-pressure air pipe enters indoor set and stops refrigerant from off-premises station and enters indoor set by the liquid pipe from off-premises station, the below concrete operating process of explanation.
