Description

Technical Field

[0001] The present invention relates to the technical field of energy-saving refrigeration equipment, in particular to a temperature-adjustable heat pump dehumidifier and a temperature adjustment method. Background Art

[0002] A heat pump dehumidifier combines a refrigeration cycle with air treatment technology, achieving air dehumidification and temperature regulation through the phase change cycle of the refrigerant. Traditional dehumidifiers primarily utilize a compression refrigeration cycle, dehumidifying air through the phase change process of the refrigerant in the evaporator. While highly efficient in low-temperature, high-humidity environments, they operate in a single mode (fixedly performing either cooling or heating dehumidification) across varying ambient temperature and humidity conditions. This results in low energy efficiency and often requires reliance on electric auxiliary heating to compensate for insufficient heating capacity, further exacerbating energy consumption.

[0003] Traditional heat pump dehumidifiers are mainly divided into two working modes: a cooling dehumidification mode suitable for high temperature and high humidity environments and a heating dehumidification mode suitable for low temperature and high humidity environments. They adopt a reversible cycle design and realize rapid switching between cooling and heating modes through a four-way reversing valve. They can intelligently select the optimal operating mode based on the real-time monitored temperature and humidity parameters. Under the cooling and dehumidification conditions, the system gives priority to using the cooling effect of the evaporator for dehumidification, and at the same time preheats the supply air through the waste heat recovered by the condenser; in the heating and dehumidification mode, the refrigerant flow direction is adjusted to achieve heating and drying of the air. In the existing technology, the heating and cooling dehumidification modes adopt a reverse cycle design and a four-way reversing valve for switching control. However, since the structural settings and materials of the evaporating heat exchanger and the condensing heat exchanger need to meet the two working conditions at the same time, higher production costs are required and the structure is easily damaged.

[0021] Compared with the prior art, the present invention provides a temperature-adjustable heat pump dehumidifier and a temperature adjustment method, which have the following beneficial effects:

[0022] 1. This temperature-adjustable heat pump dehumidifier adjusts the intake volume of dry gas input into the air supply space through the air intake processing channel and adjusts the exhaust volume of humid gas discharged from the air supply space through the exhaust processing channel through the setting of several air volume adjustment units of the air volume adjustment mechanism, so as to maintain the balance between the input of dry gas from the external environment to the air supply space and the output of humid gas from the air supply space to the external environment, thereby reducing the energy consumption of the air flow exchange between the external environment and the air supply space driven by each air volume adjustment unit, and replacing the evaporative heat exchanger and the condensing heat exchanger inside the side heat exchange unit, replacing the heat exchange structure fitted with the side heat exchange unit between the evaporative heat exchanger and the condensing heat exchanger, replacing the evaporative heat absorption with the condensation heat release, and changing the heat exchange mode of the side heat exchange unit according to the temperature of the external air in the use environment, thereby more effectively treating the input gas, more effectively achieving the temperature and humidity adjustment of the input gas, and effectively saving energy.

[0023] 2.

[0024] 3. In this temperature-adjustable heat pump dehumidifier, during the condensation and drying process of the gas inside the gas heat exchange pipe, moisture condenses and gathers to the lowest point of the gas heat exchange pipe under the action of gravity, and then the gathered moisture is collected into the drain tank through the liquid seal connecting pipe and the drain connecting pipe and then discharged.

This type of temperature-adjustable heat pump dehumidifier has a heat pump heat exchange system in which the refrigerant flow direction in the evaporative heat exchanger, condensing heat exchanger, and compression drive mechanism is set to a constant value. The evaporative heat exchanger and the condensing heat exchanger are driven to move when the dehumidification working condition is adjusted only through the setting of two transfer drive units. During the movement, the heat exchange transfer track and the heat exchange avoidance track are set separately to provide an effective avoidance space to avoid interference between the evaporative heat exchanger and the condensing heat exchanger during the movement, thereby replacing the evaporation heat absorption with the condensation heat release. The heat exchange mode of the side heat exchange unit can be changed according to the temperature of the external gas in the use environment, and the input gas can be processed more effectively, effectively avoiding the extra energy loss required for conventional adjustment such as electric heating, and can more effectively achieve the temperature and humidity adjustment of the input gas while effectively saving energy.

[0038] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0039] As introduced in the background technology, there are deficiencies in the existing technology. In order to solve the above technical problems, this application proposes a temperature-adjustable heat pump dehumidifier and a temperature adjustment method.

[0040] Example 1:

[0041] See also Figures 1-11 , a temperature-adjustable heat pump dehumidifier includes a protective shell 1, an air intake processing channel 2 and an exhaust processing channel 3 are respectively provided inside the protective shell 1, and the air intake processing channel 2 and the exhaust processing channel 3 are both connected to the external environment and the air supply space; an air volume adjustment mechanism 4 is also provided inside the protective shell 1, and the air volume adjustment mechanism 4 includes a plurality of air volume adjustment units 41, and the same number of each air volume adjustment unit 41 is evenly distributed inside the air intake processing channel 2 and the exhaust processing channel 3. Each air volume adjustment unit 41 can synchronously adjust the air intake volume of the air intake processing channel 2 and the exhaust volume of the exhaust processing channel 3 to maintain the external environment and the air supply space The air pressure balance between them; a heat pump heat exchange system is also provided inside the protective shell 1, and the heat pump heat exchange system includes an evaporative heat exchanger 5, a condensing heat exchanger 6, a compression drive mechanism 7 and a position transfer mechanism 8. The compression drive mechanism 7 can drive the refrigerant to circulate inside the evaporative heat exchanger 5 and the condensing heat exchanger 6; the air intake processing channel 2 includes a heat exchange airflow channel 21 and a side heat exchange unit 22, and the position transfer mechanism 8 can drive the evaporative heat exchanger 5 and the condensing heat exchanger 6 to move and replace them inside the side heat exchange unit 22, thereby replacing the dehumidification condition of the humid airflow flowing through the heat exchange airflow channel 21 from a cooling dehumidification condition to a heating dehumidification condition.

[0042] During specific use, the air supply space (the space that needs to be dehumidified) is first connected to the exhaust end of the air intake processing channel 2 inside the protective shell 1 through a plurality of air supply channels, and the air supply space is connected to the air intake end of the exhaust processing channel 3 inside the protective shell 1 through a plurality of return air channels. The exhaust processing channel 3 can be connected to a treatment device for treating pollutants inside the air supply space, and the protective shell 1 and the parts of the air intake processing channel 2 and the exhaust processing channel 3 that are in contact with the air are all anti-corrosion devices.

[0043] By setting up several air volume regulating units 41 of the air volume regulating mechanism 4, the air intake volume of the dry gas input into the air supply space through the air intake processing channel 2 is adjusted, and the exhaust volume of the humid gas discharged from the air supply space through the exhaust processing channel 3 is adjusted to maintain the air pressure balance between the external environment and the air supply space, so as to maintain the balance of the dry gas input from the external environment to the air supply space and the humid gas output from the air supply space to the external environment, while ensuring the same ventilation efficiency. The additional power loss caused by the air pressure imbalance of each air volume regulating unit 41 is reduced, and the energy consumption of the air flow exchange between the external environment and the air supply space is reduced; and the gas input from the air intake processing channel 2 is cooled and dehumidified by the heat pump heat exchange system. In specific use, the evaporation heat exchanger 5 and the condensation heat exchanger 6 can be driven to move to the side according to the actual use environment (winter environment and summer environment) through the position transfer mechanism 8. The heat exchange unit 22 is replaced internally, and the dehumidification condition of the humid air flow flowing through the heat exchange air flow channel 21 is replaced from a cooling dehumidification condition to a heating dehumidification condition. Specifically, the evaporative heat exchanger 5 and the condensing heat exchanger 6 are moved inside the side heat exchange unit 22 for replacement, and the heat exchange structure fitted with the side heat exchange unit 22 is replaced between the evaporative heat exchanger 5 and the condensing heat exchanger 6, and the evaporation heat absorption and condensation heat release are replaced. The heat exchange mode of the side heat exchange unit 22 can be changed according to the temperature of the external air in the use environment, and the input gas can be processed more effectively to ensure that the gas input to the air supply space meets the requirements. While changing the heat exchange mode, the heat medium flow direction inside the heat pump heat exchange system is not adjusted, and the extra energy loss of conventional adjustment such as electric heating can be effectively avoided, and the temperature and humidity adjustment of the input gas can be more effectively achieved while effectively saving energy.

[0044] Example 2:

[0045] See also Figures 1-11 , the difference from the above embodiment is that the air volume regulating unit 41 includes a fan mounting frame 411, the fan mounting frame 411 is fixedly mounted with a fan volute 412, and a centrifugal impeller 413 is rotatably arranged inside the fan volute 412; the blade directions of the centrifugal impellers 413 of the air volume regulating unit 41 located in the air intake processing channel 2 and the exhaust processing channel 3 are opposite, and when the centrifugal impellers 413 rotate synchronously, the airflows provided in the air intake processing channel 2 and the exhaust processing channel 3 respectively move in opposite directions.

[0046] During specific use, the centrifugal impellers 413 of the air volume adjustment units 41 can be driven to rotate synchronously by the same power source, and the centrifugal impellers 413 can be driven to rotate synchronously at the same time. Then, by setting the centrifugal impellers 413 of the same specifications, when the centrifugal impellers 413 rotate synchronously inside the corresponding fan volute 412, the air flow movement directions provided in the air intake processing channel 2 and the exhaust processing channel 3 are opposite, and the same instantaneous air flow rate can be provided in the air intake processing channel 2 and the exhaust processing channel 3 respectively, thereby ensuring the balance between the input of dry gas from the external environment to the air supply space and the output of moist gas from the air supply space to the external environment.

[0047] The air intake processing channel 2 also includes an air intake diversion unit 23, an exhaust convergence unit 24 and a collection and drainage unit 25. The heat exchange air flow channel 21 includes an external heat exchange cavity 211 and a plurality of gas heat exchange pipes 212; the collection and drainage unit 25 includes a plurality of drainage connecting pipes 251 and a plurality of liquid seal connecting pipes 252. Each drainage connecting pipe 251 is connected to the lowest point of each gas heat exchange pipe 212 through the liquid seal connecting pipe 252; each drainage connecting pipe 251 is connected to the drainage tank 253 at one end away from the corresponding liquid seal connecting pipe 252.

[0048] The air intake diversion unit 23 includes a diversion connecting tube 231 and a diversion mounting plate 232. The diversion mounting plate 232 is fixed inside one end of the diversion connecting tube 231, and the other end of the diversion connecting tube 231 is connected to an air volume regulating unit 41; one end of each gas heat exchange pipe 212 extends into the diversion connecting tube 231 and is fixed between the diversion mounting plate 232.

[0049] The exhaust gas confluence unit 24 includes a confluence connecting tube 241 and a confluence mounting plate. The confluence mounting plate is fixed inside one end of the confluence connecting tube 241, and the other end of the confluence connecting tube 241 is connected to an air volume regulating unit 41; the other end of each gas heat exchange pipe 212 extends into the interior of the confluence connecting tube 241 and is fixed between the confluence mounting plate.

[0050] The side heat exchange unit 22 includes a connecting heat exchange cavity 221, which is connected to the outside heat exchange cavity 211, and the outer wall of the connecting heat exchange cavity 221 is covered with a thermal conductive silicone layer 222; driven by the position transfer mechanism 8, after the evaporating heat exchanger 5 and the condensing heat exchanger 6 are replaced inside the side heat exchange unit 22, the evaporating heat exchanger 5 and the condensing heat exchanger 6 can both maintain contact with the thermal conductive silicone layer 222.

[0051] During specific use, the split connection tube 231 of the air intake split unit 23 is connected to the output end of the fan volute 412 of one air volume regulating unit 41, and the split connection tube 231 of the exhaust converging unit 24 is connected to the input end of the fan volute 412 of the other air volume regulating unit 41; through the power output by the two air volume regulating units 41, the air flow can enter each gas heat exchange pipe 212 from the split connection tube 231 and pass through the gas heat exchange pipe 212 and be output through the converging connection tube 241. In the process of the gas moving inside the gas heat exchange pipe 212, it can exchange heat with the flowing refrigerant (such as kerosene, silicone oil and other flowing heat media) inside the external heat exchange cavity 211, and can exchange heat with the gas inside the gas heat exchange pipe 212 and penetrate into the external heat exchange cavity 211 through each gas heat exchange pipe 212, so as to ensure that the gas heat exchange pipe 212 and the external heat exchange cavity 2 11. The heat exchange efficiency of the refrigerant flowing inside the gas heat exchange pipe 212 can fully ensure the heat exchange and drying effect of the gas inside the gas heat exchange pipe 212. During the condensation and drying process of the gas inside the gas heat exchange pipe 212, moisture condenses and gathers to the lowest point of the gas heat exchange pipe 212 under the action of gravity, and then the gathered moisture is collected into the drain tank 253 through the liquid seal connecting pipe 252 and the drain connecting pipe 251 and then discharged. Through the U-shaped setting of the liquid seal connecting pipe 252, a liquid seal can be formed inside the liquid seal connecting pipe 252 to prevent the gas inside the gas heat exchange pipe 212 from overflowing to the drain connecting pipe 251 through the liquid seal connecting pipe 252 (in specific use, the liquid inside the drain tank 253 can be reversely pressed from each drain connecting pipe 251 into the corresponding liquid seal connecting pipe 252 by a liquid pump to form a liquid seal before the gas is dried), thereby separating the moisture from the gas input into the air intake processing channel 2.

[0052] The external heat exchange cavity 211 is connected to the connecting heat exchange cavity 221, and when in use, structures such as impellers that promote the movement of the flowing refrigerant are provided inside the external heat exchange cavity 211 and the connecting heat exchange cavity 221, so that the temperature of the flowing refrigerant inside the external heat exchange cavity 211 and the connecting heat exchange cavity 221 remains relatively uniform, and thus, through the setting of the thermal conductive silicone layer 222, the part of the connecting heat exchange cavity 221 that contacts the evaporative heat exchanger 5 or the condensing heat exchanger 6 can be effectively filled through the deformation ability of the thermal conductive silicone layer 222, thereby ensuring the heat exchange effectiveness between the flowing refrigerant inside the connecting heat exchange cavity 221 and the refrigerant inside the evaporative heat exchanger 5 or the condensing heat exchanger 6, thereby improving the effectiveness of the gas drying treatment and temperature adjustment of the air intake processing channel 2.

[0053] Example 3:

[0054] See also Figures 1-11, the difference from the above embodiment is that the position transfer mechanism 8 includes a position transfer track 81 and two transfer drive units 82. The two transfer drive units 82 can respectively drive the evaporation heat exchanger 5 and the condensation heat exchanger 6 to move along the restriction of the position transfer track 81; the position transfer track 81 includes an internal heat exchange track 811, an external heat exchange track 812, a heat exchange transfer track 813 and a heat exchange avoidance track 814. Both ends of the heat exchange transfer track 813 and the heat exchange avoidance track 814 are respectively connected to the internal heat exchange track 811 and the external heat exchange track 812.

[0055] The compression drive mechanism 7 includes a compressor 71, a gas-liquid separator 72, an external forced heat exchanger 73 and a refrigerant storage tank 74; the evaporative heat exchanger 5 includes a low-pressure liquid inlet hose 51 and a low-pressure exhaust hose 52; the condensing heat exchanger 6 includes a high-pressure air inlet hose 61 and a high-pressure liquid discharge hose 62; the evaporative heat exchanger 5 is connected to the discharge end of the refrigerant storage tank 74 through the low-pressure liquid inlet hose 51 and the expansion valve, and the evaporative heat exchanger 5 is connected to the air inlet end of the compressor 71 through the low-pressure exhaust hose 52 and the gas-liquid separator 72; the condensing heat exchanger 6 is connected to the exhaust end of the compressor 71 through the high-pressure air inlet hose 61, and the condensing heat exchanger 6 is connected to the liquid inlet end of the refrigerant storage tank 74 through the high-pressure liquid discharge hose 62.

[0056] The internal heat exchange track 811 is set on one side of the side heat exchange unit 22, and the external heat exchange track 812 is set on one side of the external forced heat exchanger 73; the two transfer drive units 82 can respectively drive the evaporating heat exchanger 5 and the condensing heat exchanger 6 to move in opposite directions, and drive the evaporating heat exchanger 5 and the condensing heat exchanger 6 to move inside the heat exchange transfer track 813 and the heat exchange avoidance track 814 respectively, so as to switch the positions of the evaporating heat exchanger 5 and the condensing heat exchanger 6.

[0057] In actual use, the refrigerant flow direction of the heat pump heat exchange system in the evaporating heat exchanger 5, the condensing heat exchanger 6, and the compression drive mechanism 7 is set to be constant. Only the two transfer drive units 82 are set to drive the evaporating heat exchanger 5 and the condensing heat exchanger 6 to move when adjusting the dehumidification working condition. During the movement, the heat transfer track 813 and the heat avoidance track 814 are respectively set to provide effective avoidance space to avoid interference between the evaporating heat exchanger 5 and the condensing heat exchanger 6 during the movement.

[0058] In the cooling and dehumidification mode, the evaporative heat exchanger 5 is bonded to the side heat exchange unit 22 (the portion where the heat exchange cavity 221 is in contact with the evaporative heat exchanger 5 is effectively filled by the deformation capability of the thermally conductive silicone layer 222), and the condensing heat exchanger 6 is bonded to the external forced heat exchanger 73. Specifically, the external forced heat exchanger 73 is provided with a forced exhaust fan and a heat exchange radiator. The heat exchange radiator can be bonded to the condensing heat exchanger 6 through the thermally conductive silicone, and the forced exhaust fan drives the heat exchange between the heat exchange radiator and the external environment.

[0059] In the heating and dehumidification mode, the evaporation heat exchanger 5 is attached to the external forced heat exchanger 73, and the condensation heat exchanger 6 is attached to the side heat exchange unit 22;

[0060] In the above two working conditions, the direction of refrigerant flow is the same. The high-pressure steam output from the output end of the compressor 71 (the refrigerant steam is compressed by the compressor 71) is input into the condensing heat exchanger 6 through the high-pressure air inlet hose 61. The high-pressure steam produces high-pressure liquid after heat exchange inside the condensing heat exchanger 6. The high-pressure liquid is input into the refrigerant storage tank 74 through the high-pressure discharge hose 62. The high-pressure liquid output from the refrigerant storage tank 74 is throttled and reduced in pressure by the expansion valve to produce low-pressure liquid. The low-pressure liquid is input into the evaporating heat exchanger 5 through the low-pressure liquid inlet hose 51. The low-pressure liquid produces low-pressure steam after heat exchange inside the evaporating heat exchanger 5. The low-pressure steam is then input into the input end of the compressor 71 through the low-pressure exhaust hose 52, and the cycle continues.

[0061] During specific use, the evaporation heat exchanger 5 and the condensation heat exchanger 6 can be driven to move respectively by the transfer drive unit 82, and the evaporation heat exchanger 5 or the condensation heat exchanger 6 that is in contact with the side heat exchange unit 22 (or the external forced heat exchanger 73) for heat exchange can be replaced, thereby replacing the evaporation heat absorption with the condensation heat release, and the heat exchange mode of the side heat exchange unit 22 can be changed according to the temperature of the external gas in the use environment, so that the input gas can be processed more effectively, effectively avoiding the extra energy loss required for conventional regulation such as electric heating, and can more effectively achieve the temperature and humidity regulation of the input gas while effectively saving energy.
