Abstract
The utility model relates to an outdoor machine of an air conditioner, which comprises a condenser, a compressor, a four-way change valve, a low-pressure valve, a high-pressure valve, a desiccator and a throttling element, wherein, the desiccator comprises a coppery shell body, a drying agent which is arranged in the coppery shell body, a filter screen and a baffle plate. The utility model is characterized in that a spring is also arranged in the coppery shell body, and the coppery shell body is only provided with one opening. The drying agent, the filter screen, the spring and the baffle plate are orderly arranged in the coppery shell body from the inner side to the opening. Both of the condenser and the throttling element are communicated with an opening of the desiccator. Since one end of the desiccator is closed, the utility model can only be connected with a bypass of a refrigeration system. Therefore, the pressure in the desiccator is basically kept constant. The drying agent can not be subjected to the continuous impact of a cooling medium, the rate of wear of the drying agent is reduced, and the service life of the drying agent is effectively prolonged. Thus, the trouble-free operation of the air conditioner is guaranteed.
Description
The utility model relates to a kind of air-conditioner outdoor unit.
The present air-conditioner outdoor unit that uses, its drier is connected between heat exchanger and the restricting element, and refrigerant is by an end of the drier other end of flowing through, and what play desiccation is the drier (molecular sieve etc.) that is contained between drier baffle plate and the screen pack.After long-term the use, find, along with the air-conditioner prolongation of the duration of runs, drier (as molecular sieve) can wear and tear gradually under the direct impact of liquid state or gaseous coolant and diminish, like this, volume space between drier baffle plate and the screen pack will become greatly comparatively speaking, and just the drier molecular cell space of moving each other increases.Under the impact of same coolant quantity, the probability that the drier molecular cell collides each other increases, and impact velocity is accelerated, and wearing and tearing are also accelerated.Time one is long, drier (as molecular sieve) will be by original graininess pulverize powder and circulate with the refrigerant participation system gradually, cause the obstruction of air-conditioner refrigerating system pipeline, cooling or heating effect is undesirable, also can cause the compressor cisco unity malfunction when serious or burns.
The pressure that the purpose of this utility model provides in a kind of drier keeps constant substantially, the operating period limit for length of drier, the air-conditioner outdoor unit of compression function operate as normal.
In order to achieve the above object, the utility model is achieved in that it comprises condenser, compressor, four-way change-over valve, low pressure valve, high pressure valve, drier and restricting element; Drier comprises copper shell, is located at drier, screen pack and baffle plate in the copper shell; It is characterized in that: also be provided with spring in the copper shell, it has only an opening; Drier, screen pack, spring and baffle plate successively by interior in opening is arranged on copper shell; Condenser, restricting element all with the open communication of drier.The opening of drier down, restricting element is by the open communication of tube connector and drier, condenser is communicated with tube connector by tube connector.The utility model compared with prior art, its advantage is, a because end of this drier sealing, can only be connected in the refrigeration system bypass, therefore the pressure in the drier keeps constant substantially, and drier can not be subjected to the bump of refrigerant, greatly reduces the rate of wear, effectively prolong the useful life of drier, guaranteed the trouble-free operation of air-conditioner.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of drier.
Below in conjunction with drawings and Examples the utility model is done further detailed description:
As shown in Figure 1, it comprises condenser 1, compressor 2, four-way change-over valve 3, low pressure valve 4, high pressure valve 5, drier 7 and restricting element 6.Drier 7 comprises copper shell, is located at drier 14, screen pack 10, spring 15 and baffle plate 11 in the copper shell; Copper shell has only an opening 12, and drier 14, screen pack 10, spring 15 and baffle plate 11 are provided with to opening 12 by interior successively; Condenser 1, restricting element 6 all are communicated with the opening 12 of copper shell.In the present embodiment, the opening 12 of copper shell down, restricting element 6 is communicated with the opening 12 of copper shell by tube connector 8, condenser 1 passes through tube connector 9 and is communicated with tube connector 8.When air-conditioner turned round, refrigerant was filled the volume of copper shell 7 under the effect of pressure; During the air-conditioner stall, the refrigerant that copper shell is 7 li flows back to pipeline again under pressure and deadweight, participate in the new circulation of refrigerant, so go round and begin again, and in the start-stop conversion of air-conditioner, the refrigerant in the dry air-conditioner.This kind drying device is in the whole operation process of air-conditioner, when the volume space of drier 14 changes a little, spring 15 will promote screen pack 10 and move to drier 14 directions under the effect of spring force, finally make drier 14 be in a kind of state that is compressed all the time, the space of control drier 14 molecular cells, thus its movement velocity and impact velocity controlled.
