Compared with the existing dehumidifier 100, the power consumption is greatly reduced under the same air quantity, and the dehumidifier has higher dehumidification capacity and energy efficiency ratio.

Specifically: the dehumidifier 100 of the present application comprises a housing 10, wherein the housing 10 comprises a first panel 11, a second panel 13, a third panel 15 and a fourth panel 17 which are connected end to end in sequence; the evaporator 20, the condenser 30 and the sensible heat exchanger 70 are all arranged in the shell 10, the shell 10 is internally provided with a first partition board 81, a second partition board 82, a third partition board 83 and a fourth partition board 84 which mainly play a role in guiding flow, and the shell 10 is divided into a plurality of independent chambers by the arrangement of the positions of the first partition board 81, the second partition board 82, the third partition board 83, the fourth partition board 84 and the sensible heat exchanger 70, so that the air flow between all the flow paths can not generate the condition of movement, and all the flow paths are ensured to flow according to respective air channels.

The specific arrangement within the housing 10 is as follows: the fourth panel 17 is provided with an air outlet 171, and the cross-flow fan 90 is arranged adjacent to the air outlet 171; one end of the two-display heat exchanger 70, which is far away from the cross-flow fan 90, is adjacently arranged, and the end parts, which are close to the cross-flow fan 90, are far away from each other; one ends of the first partition board 81 and the third partition board 83 are respectively connected to two ends of the sensible heat exchanger 70, and the other ends of the first partition board 81 and the second partition board 82 are respectively connected to the first panel 11 and the third panel 15, and enclose to form a second accommodating cavity 103; one ends of the second partition 82 and the fourth partition 84 are respectively connected to two ends of the other sensible heat exchanger 70, and the other ends of the second partition 82 and the fourth partition 84 are respectively connected to the second panel 13 and the third panel 15 and enclose a third accommodating cavity 105; the first partition 81, the second panel 13, the fourth panel 17, the third panel 15, the third partition 83, and the wall surfaces of the two-stage heat exchanger 70 define a first accommodating chamber 101; the first panel 11 and the second panel 13 are respectively provided with a first air inlet 111 and a second air inlet 152 corresponding to a first air inlet 711, and the fourth panel 17 is provided with an air outlet 171;

thus, the outside air taken in from the first air intake port 111 flows in accordance with the first flow path (referred to as a first air flow 71 a) formed in the second accommodating chamber 103; the outside air taken in from the second air intake port 152 flows in accordance with the second flow path (referred to as the second air flow 72 a) formed in the third accommodating chamber 105.

When the dehumidification is performed, the cross flow fan 90 is started, the first air flow 71a and the second air flow 72a are pre-cooled in advance through the first air duct 71 of each heat-displaying exchanger 70, so that the air reaches a saturated state or a near saturated state when reaching the front end of the evaporator 20, then the air is cooled, dehumidified and condensed into low-temperature and low-humidity air through the evaporator 20, then enters the second air duct 73 of the heat-displaying exchanger 70, and finally is blown out to the indoor environment from the air outlet of the cross flow fan 90 after being heated through the condenser 30.

Taking one sensible heat exchanger 70 as an example, the air flow in the sensible heat exchanger 70 enters the first air duct 71, dehumidifies through the evaporator 20, enters the second air duct 73 of the sensible heat exchanger 70, and then flows out through the condenser 30. The air in the first air duct 71 is high-temperature and high-humidity air, and the air in the second air duct 73 is cooled and dehumidified by the evaporator 20 to form low-temperature and low-humidity air.

Because the first air duct 71 and the second air duct 73 are adjacent to each other and are not communicated with each other in the heat-development exchanger 70, the high-temperature and high-humidity air in the first air duct 71 is affected by the low-temperature and low-humidity air in the second air duct 73, the two are subjected to heat exchange, the temperature of the high-temperature and high-humidity air in the first air duct 71 is reduced, the saturated state or the near saturated state is reached in advance, and then the high-temperature and high-humidity air in the first air duct 71 passes through the evaporator 20 to be further dehumidified, so that the dehumidification amount of the high-temperature and high-humidity air in the first air duct 71 is improved, namely, the refrigerating capacity of the evaporator 20 is saved, and the dehumidification capacity of the evaporator 20 is improved, so that the dual purposes of dehumidification capacity and high energy efficiency ratio are achieved.

In addition, at least two sensible heat exchangers 70 are provided, that is, at least two air flow paths are formed in the dehumidifier 100, and the dehumidifying amount of the high-temperature and high-humidity air in the first air duct 71 of each sensible heat exchanger 70 is increased. Therefore, both the dehumidifying capability and the dehumidifying efficiency of the dehumidifier 100 of the present application are greatly improved. Meanwhile, each sensible heat exchanger 70 is provided with an evaporator 20, which can further improve the dehumidifying efficiency and the dehumidifying capacity of the dehumidifier 100.

Meanwhile, the air dehumidified by the evaporator 20 flows through a corresponding condenser 30 disposed at the second air outlet 733, and is heated and returned to the indoor environment, so as to ensure that the temperature of the air dehumidified by the dehumidifier 100 is not different from the temperature of the indoor air, and the air dehumidified by the dehumidifier is not unsuitable for the indoor environment.

Meanwhile, it can be appreciated that the housing 10 can be manufactured by plastic materials through injection molding, and a detachable housing 10 structure, that is, a plurality of split shells are spliced and assembled to form the housing 10. The shape of the housing 10 may take the form of a circle, square, regular polygon or other irregular shape. It will be appreciated that the air inlet and air outlet of the housing 10 may also be provided with a damper assembly so that the opening and closing of the air duct may be precisely controlled.

The present application may further provide a compressor (not shown), where the compressor is connected with the evaporator 20 and the condenser 30 through a throttling component and a pipeline system to form a refrigerant circulation loop, and the compressor may be installed in the same housing 10 as the evaporator 20 and the condenser 30 to form a dehumidifier 100 together, or may adopt a multi-split air conditioner system similar to a central air conditioner, where one compressor drives a plurality of dehumidifiers 100.

The principle of operation of the sensible heat exchanger 70 according to an embodiment of the application is: the sensible heat exchanger 70 is a type of heat exchanger which only transfers heat and does not transfer mass, and when in operation, two air flows cross through the heat exchange core, the first air duct 71 and the second air duct 73 are separated by a separation plate, two fluid at two sides of the separation plate have temperature difference, and the two fluid exchanges heat through the separation plate, so that the heat transfer process is completed. The partition plate is plate-shaped and sheet-shaped, and the part with the partition function is not provided with any through holes, so that only heat exchange and no mass exchange can be realized; the material can be plastic or metal, but is not limited to the two materials. The sensible heat exchanger 70 shape includes, but is not limited to, a regular polygon, and may be various shaped bodies with other even sides.

The evaporator 20 and the condenser 30 are fin-tube heat exchangers or microchannel heat exchangers.

The evaporator 20 of an embodiment of the present application: by means of the heat absorbed by the low temperature low pressure refrigerant in the refrigerant circulation loop, the moisture in the air passing through the evaporator 20 is condensed out, and the dehumidification purpose is achieved. The evaporator 20 may employ a fin and tube heat exchanger or a microchannel heat exchanger. In the case of a fin-tube heat exchanger, the fin-tube heat exchanger can take the form of a plurality of rows of tubes, and is generally preferably 1-4 rows, the tube diameter of the fin-tube heat exchanger is preferably 4-10 mm, the fin type is preferably windowed, and the fin distance is preferably 1.2-1.6 mm. The fin tube type heat exchanger arranged in this way can furthest pass through air and perform full heat exchange with the air on the premise of saving installation space and materials. In the case of a microchannel heat exchanger, 1 to 2 rows are generally preferred, the width of the flat tube is preferably 8 to 20mm, the thickness is preferably 1.2 to 2.0mm, and the sheet distance is preferably 1.1 to 1.4mm. The micro-channel heat exchanger arranged in this way can improve heat exchange efficiency.

Condenser 30 of an embodiment of the present application: the low-temperature low-humidity air flowing through the condenser 30 is heated by the high-temperature high-pressure refrigerant gas in the refrigerant circulation loop, so that the purpose of reheating the air is achieved, and the influence of the dehumidification process on the environment temperature is reduced. The condenser 30 may be a fin-tube heat exchanger or a microchannel heat exchanger. In the case of a fin-tube heat exchanger, the fin-tube heat exchanger can take the form of a plurality of rows of tubes, and is generally preferably 1-6 rows, the tube diameter of the fin-tube heat exchanger is preferably 4-7 mm, the fin type of the fin-tube heat exchanger is preferably windowed, and the fin distance is preferably 1.2-1.6 mm. In the case of a microchannel heat exchanger, 1 to 2 rows are generally preferred, the width of the flat tube is preferably 8 to 16mm, the thickness is preferably 1.2 to 2.0mm, and the sheet distance is preferably 1.1 to 1.4mm. The advantageous effects of the arrangement of the condenser 30 are similar to those of the evaporator 20 and will not be described in detail herein.

In an embodiment of the present application, in order to prevent the air flow between the flow paths from moving, and ensure that the flow paths flow according to the respective stable air channels, the present application adopts the following design: one end of the evaporator 20 facing away from the second panel 13 is respectively abutted against the first panel 11; one end of the other evaporator 20, which is away from the second panel 13, abuts against the third panel 15, and the second accommodating chamber 103 is partitioned into a first accommodating space 1031 and a second accommodating space 1033 by the evaporator 20 and the sensible heat exchanger 70; the other evaporator 20 and the other sensible heat exchanger 70 partition the third accommodation chamber 105 into a third accommodation space 1051 and a fourth accommodation space 1053, one of the first air intake port 111 and one of the air intake ports communicates with one of the first accommodation spaces 1031, and the other of the first air intake port 111 and the other of the air intake ports communicates with one of the third accommodation spaces 1051. According to the technical scheme, the reasonable arrangement is adopted, so that the structure is compact due to the utilization of the device (the position of the evaporator 20 is set), and the partition plate assembly is saved.

Further, in order to make the arrangement more reasonable and compact, the present application abuts one end of the two condensers 30 close to the second panel 13.

In an embodiment of the present application, in order to enhance the air outlet and the dehumidification capacity of the dehumidifier 100, the first panel 11 is further provided with a third air inlet 113, and the third air inlet 113 is in communication with the second accommodating space 1033.

The cross flow fan 90 sucks the external air into the second accommodating chamber 103 through the third air inlet 113, and discharges the external air through the evaporator 20, the second air duct 73 and the condenser 30. (this is referred to as the third wind flow 73 a)

According to the technical scheme, through the arrangement of the third air inlet 113, at least one air flow channel can be additionally added to the dehumidifier 100, the air entering through the third air inlet 113 can be dehumidified through the evaporator 20 to form low-temperature low-humidity air flow, then the low-temperature low-humidity air flow enters the second air channel 73, and the low-temperature low-humidity air flow can exchange heat with the high-temperature high-humidity air which is not dehumidified in the first air channel 71, so that the air in the first air channel 71 can reach a saturated state or a near saturated state in advance, and therefore, the attenuation of the air quantity brought by the long air channel flow can be compensated, and the dehumidification energy efficiency and the dehumidification efficiency of the dehumidifier 100 can be further improved.

Further, it will be appreciated that when the wind of the third air inlet 113 is not easy to pass, more wind enters from the first air inlet 111, so that more wind can be precooled at the sensible heat exchanger 70; when the wind of the third air inlet 113 easily passes through, less wind can enter from the first air inlet 111, but more wind can enter from the third air inlet 113, and although the less wind precools, the wind is reduced, the wind quantity is improved, and the power is reduced.

In this solution, the third air inlet 113 is formed in a grid shape. The air of the third air inlet 113 is not easy to enter, so that enough air is guaranteed to be precooled, and the air of the third air inlet 113 can be guaranteed to sufficiently compensate for the attenuation of the air quantity caused by the long flow of the air channel.

Wherein, the third air inlet 113 has a porosity of P1,0< P1<1.

In another embodiment of the present application, in order to enhance the air outlet and the dehumidification amount of the dehumidifier 100, the second panel 13 may further be provided with a fourth air inlet 154, and the fourth air inlet 154 is in communication with the fourth accommodating space 1053.

The cross flow fan 90 sucks the external air into the third accommodating chamber 105 through the fourth air inlet 154, and discharges the external air through the evaporator 20, the second air duct 73 and the condenser 30. (this is referred to as the fourth wind flow 74 a)

The dehumidifier 100 may additionally have at least one air flow channel, the air entering through the fourth air inlet 154 can be dehumidified by the evaporator 20 to form a low-temperature low-humidity air flow, and then enters into the second air duct 73 to exchange heat with the air in the first air duct 71 which is not dehumidified and is high in temperature and humidity, so that the air in the first air duct 71 can reach a saturated state or a near saturated state in advance, and thus, not only can compensate for the attenuation of the air quantity caused by the long air duct flow, but also the dehumidification energy efficiency and the dehumidification efficiency of the dehumidifier 100 can be further improved.

Further, the fourth air inlet 154 is provided in a grid shape. The wind of the fourth air inlet 154 is not easy to enter, so that enough wind is ensured to pre-cool, and the wind of the fourth air inlet 154 is ensured to sufficiently compensate the attenuation of the wind quantity caused by long flow of the wind channel.

Wherein, the third air inlet 113 has a porosity of P1,0< P1<1.

In an embodiment of the present application, in order to further enhance the air output and the heat exchange effect of the dehumidifier 100, a first air compensating condenser 40 is disposed between the first partition 81 and the fourth panel 17, a fifth air inlet 115 is disposed on the first panel 11 corresponding to the first air compensating condenser 40, and the through-flow fan 90 sucks in the external air from the fifth air inlet 115 and then discharges the external air through the first air compensating condenser 40.

At this time, the principle of refrigerant circulation is: the refrigerant is compressed by the compressor to form a high-temperature and high-pressure refrigerant (the refrigerant is gas in theory at the moment) which flows to the first air supplementing condenser 40, the high-temperature and high-pressure refrigerant is primarily cooled on the first air supplementing condenser 40 and then flows to the condenser 30 for dehumidification, and then is cooled again, and then the refrigerant flows to the evaporator 20 through the throttling device (the refrigerant is liquid in theory at the moment).

The refrigerant conducts heat transfer with air on the evaporator, the refrigerant absorbs heat to condense the air, the refrigerant is also converted into gas from liquid, and the refrigerant flows to the compressor again after heat exchange of the evaporator.

The reason for providing the first supplemental air condenser 40: the heat exchange area of the condenser 30 and the required air volume of the dehumidifier 100 are larger than those of the evaporator, and the existing dehumidifier 100 adopts a technology of thickening the components of the condenser 30, but has poor efficiency, low energy efficiency and cannot increase the air volume. After the plurality of independent first air compensating condensers 40 are arranged, the area of each first air compensating condenser 40 can randomly control the heat exchange area required by the automatic adjusting condenser 30, the air quantity of the condenser 30 of the system added with the first air compensating condenser 40 is larger than that of the evaporator, the heat exchange efficiency of the condenser is effectively enhanced under the action of large air quantity, and the energy efficiency of the whole machine is improved. In the system with the first air-compensating condenser 40 from the internal heat exchange perspective, if the flow path of the first air-compensating condenser 40 is connected in series with the condenser of the system itself, the high-temperature and high-pressure refrigerant at the outlet of the compressor should enter the first air-compensating condenser 40 to exchange heat with the air at the ambient temperature preferentially, and then enter the condenser 30 to exchange heat with the air cooled by the evaporator 20, so as to ensure the utilization rate of the whole cold energy and avoid waste.

In addition, the first air-compensating air flow 41a entering from the fifth air inlet 115 is converged with the first air flow 71a and the second air flow 72a exiting from the two condensers 30 along the rear wall surface of the volute after passing through the first air-compensating condenser 40, and the first air-compensating air flow 41a exiting from the first air-compensating condenser 40 is higher than the room temperature because the first air flow 71a and the second air flow 72a exiting from the two condensers 30 may be lower than the room temperature, and after the three air flows are converged, the temperature of the air can be uniform, so that the air exhausted from the air outlet 171 approaches the room temperature, and the influence on the indoor environment comfort is reduced.

Similarly, in order to further enhance the air output and the heat exchange effect of the dehumidifier 100, a second air compensating condenser 50 may be disposed between the second partition 82 and the fourth panel 17, the first panel 11 may be provided with a sixth air inlet 156 corresponding to the second air compensating condenser 50, and the through-flow fan 90 may suck the external air from the sixth air inlet 156 and then exhaust the external air through the second air compensating condenser 50.

The second air-supplementing air flow 51a entering from the sixth air inlet 156 is converged with the first air flow 71a and the second air flow 72a exiting from the two condensers 30 along the rear wall surface of the volute after passing through the second air-supplementing condenser 50, and the first air flow 71a and the second air flow 72a exiting from the two condensers 30 may be lower than the room temperature, while the second air-supplementing air flow 51a exiting from the first air-supplementing condenser 40 is higher than the room temperature, and after the three air flows are converged, the temperature of the air can be uniform, so that the air exiting from the air outlet 171 approaches the room temperature, and the influence on the indoor environment comfort is reduced.

Activated carbon has carbon lattice with developed pores of different shapes and sizes, and has greatly increased specific surface area and raised adsorption capacity. HEPA (High efficiency particulate air Filter) Chinese means a high-efficiency air filter, a filter screen meeting HEPA standards, and an effective rate of 99.7% for 0.1 micron and 0.3 micron, the HEPA screen being characterized by air passing but fine particles not passing. It has particle eliminating efficiency below 0.3 micron (1/200 of hair diameter) up to 99.97%, and is the most effective filter medium for fume, dust, bacteria, etc. HEPA is divided into five materials of PP filter paper, glass fiber, composite PP PET filter paper, melt-blown terylene non-woven fabric and melt-blown glass fiber. The characteristics are as follows: the air resistance is large, the dust holding capacity is large, the filtering precision is high, and the air-conditioner can be processed into various sizes and shapes according to the needs, and is suitable for different machine types. Through active carbon layer and HEPA filter layer, but the organic pollutant and the granule that get the air are all purified, promote the purification quality of air.
