Abstract
The utility model discloses take four -way reversing valve defroster's industry dehumidifier belongs to industry dehumidification equipment field, and it is chronic to have solved the white modeization of current industry dehumidifier natural draft ization frost, changes the poor problem of white effect, the technical scheme of adoption: including evaporimeter, condenser, compressor and four -way reversing valve, the import of compressor and four -way reversing valve's C mouth intercommunication, the import of condenser and four -way reversing valve's D mouth intercommunication, the export of evaporimeter and four -way reversing valve's B mouth intercommunication, the export of condenser and the import intercommunication of evaporimeter.
Description
technical field:
The utility model belongs to industrial dehumidification equipment field, particularly relates to a kind of industrial dehumidifier with four-way change-over valve defroster.
background technology:
As shown in Figure 1, dehumidifier on existing market, Defrost mode all adopts stopping compressor operation, dehumidifier gravity-flow ventilation defrost, and this structure also exists following problem:
1) when low temperature (0-8 degree Celsius), dehumidifier frosting can be thicker, adopts gravity-flow ventilation defrost poor effect, defrost is incomplete, if each defrost is not complete, after the time grown, water on evaporimeter will freeze, and affects effect on moisture extraction, serious meeting liquid hammer damage compressor.
2) gravity-flow ventilation defrost mode, the defrost time is long, and the fluctuation of dehumidifying space humidity is comparatively large, and the place that some humidity requirements are high is just inapplicable.
utility model content:
The utility model overcomes the deficiency that prior art exists, solve the existing industrial dehumidifier gravity-flow ventilation defrost mode defrost time long, the problem of defrost weak effect, aim to provide a kind of industrial dehumidifier with four-way change-over valve defroster, this industrial dehumidifier is efficient, energy-conservation, defrosting time is short, and effect on moisture extraction is good, is highly suitable for the industrial dehumidifier used at low ambient temperatures.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: the industrial dehumidifier of band four-way change-over valve defroster, comprise evaporimeter, condenser, compressor and four-way change-over valve, the import of compressor is communicated with the C mouth of four-way change-over valve, the import of condenser is communicated with the D mouth of four-way change-over valve, the outlet of evaporimeter is communicated with the B mouth of four-way change-over valve, the outlet of condenser and the inlet communication of evaporimeter.
Further, described four-way change-over valve comprises valve body, and the side of valve body is provided with Hydraulic Conirol Unit, and the below of valve body is provided with A mouth, and the top of valve body has been arranged side by side B mouth, C mouth and D mouth.
The utility model compared with prior art has following beneficial effect: industrial dehumidifier of the present utility model by setting up four-way change-over valve between evaporimeter, condenser and compressor, four-way change-over valve is utilized to change the flow direction of cold-producing medium, evaporimeter is become condenser, utilizes the cold-producing medium of HTHP to be spent completely (heat pump defrost) by the frost of evaporator surface.The mode of heat pump defrost had both kept the effect of efficient dehumidifying, can avoid again damaging compressor at low ambient temperatures.And the defrosting time of dehumidifier can be shortened, keep the moisture fluctuation of dehumidified environment little.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the utility model is described in more detail.
Fig. 1 is the structure of existing industrial dehumidifier.
Fig. 2 is the structure of the utility model industry dehumidifier.
Fig. 3 is the main TV structure schematic diagram of four-way change-over valve.
Fig. 4 is the side-looking structural representation of four-way change-over valve.
In figure: 1 is evaporimeter, 2 is condenser, and 3 is compressor, and 4 is four-way change-over valve, and 41 is valve body, and 42 is Hydraulic Conirol Unit, and 5 is blower fan.
detailed description of the invention:
As shown in figs 2-4, with the industrial dehumidifier of four-way change-over valve 4 defroster, comprise blower fan 5, evaporimeter 1, condenser 2, compressor 3 and four-way change-over valve 4, described four-way change-over valve 4 comprises valve body 41, the side of valve body 41 is provided with Hydraulic Conirol Unit 42, the below of valve body 41 is provided with A mouth, and the top of valve body 41 has been arranged side by side B mouth, C mouth and D mouth.
The import of compressor 3 is communicated with the C mouth of four-way change-over valve 4, and the import of condenser 2 is communicated with the D mouth of four-way change-over valve 4, and the outlet of evaporimeter 1 is communicated with the B mouth of four-way change-over valve 4, the outlet of condenser 2 and the inlet communication of evaporimeter 1.
When after the surperficial frosting of evaporimeter 1, electric-controlled plate is powered to four-way change-over valve 4 and is changed refrigerant flow direction, evaporimeter 1 is become condenser 2, at this time the frost on evaporimeter 1 can be removed by the cold-producing medium of HTHP rapidly, in whole defrost process, the time is short, through overtesting and test, the dehumidifier of employing heat pump frost-removal structure is more suitable for being used in low temperature environment and uses.
Industrial dehumidifier with Defrost has following three advantages: the effect 1) both having maintained efficient dehumidifying, avoids again damaging compressor at low ambient temperatures; 2) shorten the defrosting time of dehumidifier, and keep the moisture fluctuation of dehumidified environment little; 3) moisture removal of dehumidifier is increased.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-described embodiment, in the ken that those of ordinary skill in the art possess, various change can also be made under the prerequisite not departing from the utility model aim.
