Description

Technical Field

[0001] The utility model relates to the technical field of medium indirect contact heat exchange equipment, in particular to dehumidification treatment. Background Art

[0002] Conventional dehumidification processes rely on air source heat pump systems to extract heat from products, and are particularly widely used in the field of drying and dehumidification. They are also used in the fields of heating, cooling, cold storage, and cooling. The heat pump dehumidification system in the prior art generally uses an evaporator for dehumidification cycles. The dehumidification efficiency of the unit is low, and the dehumidifier makes a lot of noise during dehumidification, which seriously affects the quality of the surrounding environment. The application of existing dehumidifiers in energy-saving technologies mainly focuses on the low-temperature air discharged from the evaporator and the recovery of cold. For example, it is used to dissipate heat from the condenser. For example, the Chinese patent with publication number CN211739341U discloses a high-efficiency heat pipe energy-saving dehumidifier and provides the following technical solution. The utility model relates to a high-efficiency heat pipe energy-saving dehumidifier, which belongs to the technical field of heat pump drying and dehumidification, including a lower heat pipe heat exchanger, an evaporator, an upper heat pipe heat exchanger and a condenser. The lower heat pipe heat exchanger and the upper heat pipe heat exchanger form a closed heat pipe system. The lower end of the lower heat pipe heat exchanger is connected to the lower end of the upper heat pipe heat exchanger, and the upper end of the lower heat pipe heat exchanger is connected to the upper heat pipe heat exchanger. The upper end of the heat exchanger is connected, the air inlet of the lower heat pipe heat exchanger is connected to the system air supply port, the air outlet of the lower heat pipe heat exchanger is connected to the air inlet of the evaporator, the air outlet of the evaporator is connected to the air inlet of the upper heat pipe heat exchanger through the cold air duct, the air outlet of the upper heat pipe heat exchanger is connected to the air inlet of the condenser, the air outlet of the condenser is connected to the hot air duct, the other end of the hot air duct is connected to the air inlet of the dehumidification fan, and the air outlet of the dehumidification fan is connected to the exhaust port of the system, with the help of the heat pipe system, heat exchange without power consumption is realized, and the dehumidification efficiency of the unit is improved. However, in a high-efficiency heat pipe energy-saving dehumidifier with the above structure, the dehumidified condensed water is directly discharged to the water tank, but the temperature of this part of the water is much lower than the air temperature, so this part of the cooling capacity is wasted, resulting in an increase in the demand for compressor cooling capacity, thereby increasing noise and energy consumption. Utility Model Content

[0003] In response to the problems of high noise, high energy consumption, and waste of condensed water cooling capacity described in the background technology, the utility model proposes an energy-saving dehumidifier, which achieves the purposes of high dehumidification efficiency, energy saving and environmental protection, low noise, and ensuring the recovery of condensed water and efficient use of refrigerant.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an energy-saving dehumidifier, comprising: a condensate water heat exchanger assembly and a subcooler, the condensate water heat exchanger assembly comprising a first condensate water heat exchanger and a second condensate water heat exchanger, the first condensate water heat exchanger is located at the front end, an evaporator is arranged behind the first condensate water heat exchanger, the subcooler is installed between the second condensate water heat exchanger and the evaporator, and a condenser is installed behind the second condensate water heat exchanger.

[0005] The advantage of this design is that, through reasonable layout and component configuration, the air can fully utilize the coldness of the condensed water to achieve dehumidification when passing through the condensed water heat exchanger. At the same time, the setting of the first condensed water heat exchanger and the evaporator can pre-cool the air first, thereby improving the condensation efficiency of the water in the subsequent evaporator. In addition, through the installation of the condenser and the connection of the refrigerant flow channel, it is ensured that the entire system can continuously cool and dehumidify, thereby improving the stability and working efficiency of the system.

[0006] Preferably, the condenser is connected to one end of the compressor through a refrigerant flow channel, and the other end of the compressor is connected to the evaporator through the refrigerant flow channel.

[0007] The advantage of this design is that through the flow of refrigerant, the compressor can continuously compress the refrigerant and release the heat to the condenser and the cold to the evaporator to achieve the refrigeration effect. At the same time, the connection between the evaporator and the compressor ensures the transfer and circulation of heat, so that the dehumidifier can continue to perform dehumidification operations.

[0008] Preferably, a water receiving tray is provided at the bottom of the evaporator, a water tank group is provided below the water receiving tray, the water tank group includes a first water tank, a second water tank and a water pump, and the water receiving tray is connected to the first water tank.

[0009] The advantage of this design is that during the operation of the evaporator, the condensed water can be collected in the water receiving tray and then in the first water tank, which facilitates the subsequent utilization of the cold energy in this part of the condensed water, improves the heat recovery efficiency of the overall system, and reduces the demand for external water sources.

[0010] Preferably, the first water tank is connected to the water inlet end of the first condensate water heat exchanger and the water inlet end of the second condensate water heat exchanger through a water pipe and a water pump.

[0012] Preferably, the water outlet end of the first condensate water heat exchanger and the water outlet end of the second condensate water heat exchanger are connected to the second water tank.

[0013] The advantage of this design is that by connecting the outlet end of the second condensate heat exchanger and the second water tank, the cooled condensate can be collected in the second water tank. This part of water has released cold energy and can be used for other tasks or processed and discharged, ensuring efficient use of the system's water cycle.

[0014] Preferably, a throttling device is provided in the refrigerant flow channel between the subcooler and the evaporator.

[0015] The advantage of this design is that the throttling device can control the flow rate and flow of the refrigerant, so that the refrigerant can perform an appropriate amount of heat exchange between the subcooler and the evaporator. This incremental heat exchange can improve heat exchange efficiency and reduce energy loss.

[0016] Preferably, a fan is installed behind the condenser.

[0017] The advantage of this design is that the installation of the fan can increase the heat dissipation effect of the condenser, accelerate the cooling process of the refrigerant, and improve the working efficiency of the entire system. At the same time, the fan can also increase air flow, promote the transfer and discharge of heat, and maintain the stable operation of the system.

[0018] Compared with the prior art, the utility model has the following beneficial effects.

This design optimizes the dehumidification effect and improves the dehumidification capacity of the system.

[0020] 2. The condenser and evaporator are connected through the refrigerant flow channel, ensuring that the entire system can continuously perform cooling and dehumidification operations.

This design ensures the stability and working efficiency of the system.

[0021] 3. The water tray and water tank set at the bottom of the evaporator improve the heat recovery efficiency of the system and reduce the demand for external water sources.

These embodiments do not describe all the details in detail, nor do they limit the present utility model to only the specific embodiments described.

[0026] See also Figure 1-2 As shown, an energy-saving dehumidifier is characterized in that it includes: a condensate water heat exchanger assembly and a subcooler, the condensate water heat exchanger assembly includes a first condensate water heat exchanger 7 and a second condensate water heat exchanger 3, the first condensate water heat exchanger 7 is located at the front end, an evaporator 6 is arranged behind the first condensate water heat exchanger 7, the subcooler 4 is installed between the second condensate water heat exchanger 3 and the evaporator 6, and a condenser 2 is installed behind the second condensate water heat exchanger 3.

[0027] At present, the research on improving the energy efficiency of dehumidifiers mainly focuses on the low-temperature air in the evaporator outlet and the recycling of cold. A common application is to use low-temperature air for heat dissipation of the condenser to improve energy efficiency. However, the condensed water in the dehumidifier is usually discharged directly into the water tank, and the temperature of this part of water is often lower than the air temperature, resulting in the failure to effectively utilize the cold therein, causing energy waste. An energy-saving dehumidifier designed in the utility model adopts a reasonable layout and a new heat exchanger component to fully utilize the cold of the condensed water and achieve an efficient and energy-saving dehumidification effect. First, through the setting of the condensed water heat exchanger 7, the air can fully utilize the cold of the condensed water to increase the dehumidification amount and reduce energy consumption during the process of passing through. At the same time, the setting of the first condensed water heat exchanger 7 allows the air to be pre-cooled first, thereby improving the condensation efficiency of the water in the subsequent evaporator 6. Secondly, the condenser 2, the compressor and the evaporator 6 are connected through the refrigerant flow channel to achieve continuous cooling and dehumidification operations. The water receiving tray 9 and the water tank group 12 structure at the bottom of the evaporator 6 collect the condensed water, improve the heat recovery efficiency and reduce the demand for external water sources. The first water tank 10 is connected to the condensate heat exchanger 7 through a water pipe and a water pump 8 to ensure sufficient water supply. The outlet end of the first condensate heat exchanger 7 and the outlet end of the second condensate heat exchanger 3 are connected to the second water tank 11 to collect and utilize condensate. At the same time, a throttling device 5 is provided in the refrigerant flow channel to control the flow rate and flow of the refrigerant and improve the heat exchange efficiency. A fan 1 is installed behind the condenser 2 to increase the heat dissipation effect, accelerate the cooling process of the refrigerant, and improve the working efficiency of the system. In general, the design structure is optimized and can make full use of the coldness of the condensate to achieve an efficient and energy-saving dehumidification effect.

[0028] like Figure 1 In one embodiment shown, it is a schematic diagram of the overall structure of an embodiment of the utility model. An energy-saving dehumidifier designed by the utility model is constructed in a carefully designed system. First of all, the condensate heat exchanger assembly is the core part of the dehumidifier, which includes a first condensate heat exchanger 7 and a second condensate heat exchanger 3. The first condensate heat exchanger 7 is located at the front end, followed by an evaporator 6, and a subcooler 4 is installed between the second condensate heat exchanger 3 and the evaporator 6. The synergistic effect of the condensate heat exchanger 7 and the evaporator 6 allows moisture to be quickly condensed and quickly removed, thereby achieving efficient dehumidification.

[0029] During the dehumidification process, the condenser 2 is connected to one end of the compressor through the refrigerant flow channel, and the other end of the compressor is connected to the evaporator 6 through the refrigerant flow channel. A water receiving pan 9 is provided at the bottom of the evaporator 6, and a water tank group 12 is provided. The water tank group 12 consists of a first water tank 10, a second water tank 11 and a water pump 8. The water receiving pan 9 is connected to the first water tank 10, and the first water tank 10 is connected to the water pump 8 through a water pipe. This design ensures the flow and circulation of condensed water, so that the coldness of the condensed water can be utilized.

[0030] At the same time, the water inlet and outlet of the condensate heat exchanger are also carefully designed. The water inlet of the first condensate heat exchanger 7 and the water inlet of the second condensate heat exchanger 3 are connected to the first water tank 10, while the water outlet of the first condensate heat exchanger 7 and the water outlet of the second condensate heat exchanger 3 are connected to the second water tank 11. In addition, a fan 1 is installed behind the condenser 2 to enhance the cooling effect. At the same time, the throttling device 5 is also cleverly introduced into the refrigerant flow channel between the subcooler 4 and the evaporator 6, further improving the efficiency and performance of dehumidification.

[0031] This condensation heat exchange dehumidifier uses the coldness of condensed water to achieve dehumidification. Its working principle is based on the thermodynamic principle of condensation and evaporation. During the entire working process, the condenser 2, evaporator 6, subcooler 4 and compressor and other components cooperate with each other to achieve the purpose of efficient dehumidification.

[0032] First, the air enters the dehumidifier and passes through the first condensate heat exchanger 7. This condensate heat exchanger 7 is located at the front end of the dehumidifier, and its main function is to pre-cool the air first to improve the condensation efficiency of the water in the subsequent evaporator 6. At the same time, the cold released by the condensed water in the first condensate heat exchanger 7 is also absorbed by the air, achieving preliminary air cooling.

[0033] After the first condensation water heat exchanger 7, the air enters the evaporator 6. The evaporator 6 is connected to the refrigerant flow channel, and the refrigerant flows therein and exchanges heat with the air. Due to the precooling effect of the first condensation water heat exchanger 7, the moisture in the air is more likely to condense into water droplets and exchange heat with the refrigerant. In this way, the moisture is condensed and converted into water droplets, thereby achieving more thorough dehumidification.

[0034] Behind the evaporator 6, the subcooler 4 is arranged between the second condensate heat exchanger 3 and the evaporator 6. This arrangement produces a gradual heat exchange process, rather than suddenly performing a large amount of heat exchange in a single heat exchanger. This incremental heat exchange can improve the heat exchange efficiency and reduce energy loss; and can increase the temperature difference with the condensate heat exchanger 7, thereby improving the efficiency of heat exchange.

[0035] The second condensate heat exchanger 3 is arranged behind the supercooler 4, which plays a role in pre-cooling the condenser 2 and further condenses the water vapor in the air, greatly improving the dehumidification efficiency.

[0036] The condenser 2 is located at the end of the entire dehumidifier. Its main function is to transfer the heat released by the refrigerant from the evaporator 6 to the external environment. This can also keep the treated air at a certain temperature to prevent the air temperature from being too low and uncomfortable. The refrigerant enters the condenser 2 from the evaporator 6 through the refrigerant flow channel. After the compressor works, the refrigerant is compressed and cooled, releasing heat. A fan 1 is installed behind the condenser 2, which promotes the transfer and discharge of heat by increasing air flow and improving the heat dissipation effect.

[0037] In the whole working process, the flow and circulation of condensed water plays an important role. A water receiving pan 9 and a water tank group 12 are provided at the bottom of the evaporator 6, including a first water tank 10, a second water tank 11 and a water pump 8. The water receiving pan 9 is connected to the first water tank 10, and the condensed water is collected in the water receiving pan 9 and flows into the first water tank 10. The water pump 8 transports the condensed water from the first water tank 10 to the water inlet of the first and second condensed water heat exchangers 7 and 3. This design ensures the circulation and water supply of the condensed water, so that the coldness in the condensed water can be fully utilized, and the working efficiency and stability of the system are improved.

[0038] In general, the working process of this condensation heat exchange dehumidifier is as follows: the air is pre-cooled by the first condensation water heat exchanger 7, and then enters the evaporator 6 to exchange heat with the refrigerant, and the moisture is condensed into water droplets. The condensed water is collected and circulated by the water receiving tray 9 and the water tank, and then transported to the condensation water heat exchanger again to play a cooling role. At the same time, the refrigerant connects the compressor and the evaporator 6 through the refrigerant flow channel to achieve continuous cooling and dehumidification operations. The installation of the fan 1 increases the heat dissipation effect of the condenser 2 and improves the working efficiency of the entire system. Through this working principle and working process, this condensation heat exchange dehumidifier can dehumidify efficiently and provide a refreshing and dry environment.

[0039] like Figure 2 In one embodiment shown, it is a schematic diagram of the internal structure of an embodiment of the utility model. This condensation heat exchange dehumidifier utilizes a reasonable layout and component configuration to achieve efficient dehumidification operation. Its core part is the condensate heat exchanger assembly, including the first and second condensate heat exchangers, as well as the evaporator 6 and the subcooler 4. Through the synergistic effect of the condensate heat exchanger and the evaporator 6, moisture can be quickly condensed and removed to achieve efficient dehumidification. During the dehumidification process, the condenser 2 connects the compressor and the evaporator 6 through the refrigerant flow channel, thereby achieving continuous cooling and dehumidification operations. The compressor compresses the refrigerant to achieve a refrigeration effect. This connection method ensures the transfer and circulation of heat, allowing the dehumidifier to continuously perform dehumidification operations, improving the stability and work efficiency of the system.

[0040] In order to improve the energy recovery efficiency and reduce the demand for external water sources, a water receiving pan 9 and a water tank group 12 are provided at the bottom of the evaporator 6, including a first water tank 10, a second water tank 11 and a water pump 8. The condensed water is collected in the water receiving pan 9 and transported to the first and second condensate water heat exchangers via the water pump 8. In this way, the cold energy in the condensed water can be reused to improve the heat recovery efficiency of the overall system. In addition, this design reduces the dependence on external water sources and increases the sustainability of the system.

[0041] In addition, the water inlet and outlet of the condensate heat exchanger are carefully designed to ensure the flow and circulation of condensate. The water inlet of the first condensate heat exchanger 7 is connected to the first water tank 10 with the water inlet of the second condensate heat exchanger 3, and the water outlet of the first condensate heat exchanger 7 is connected to the second water tank 11 with the water outlet of the second condensate heat exchanger 3. This design ensures that the first and second condensate heat exchangers can be fully supplied with water, further improving the operating efficiency and stability of the system. In addition, a fan 1 is installed behind the condenser 2 to enhance the refrigeration effect. The installation of the fan 1 can increase the heat dissipation effect of the condenser 2, accelerate the cooling process of the refrigerant, and improve the working efficiency of the entire system. At the same time, the fan 1 can also increase the air flow, promote the transfer and discharge of heat, and maintain the stable operation of the system. Finally, a throttling device 5 is provided in the refrigerant flow channel between the subcooler 4 and the evaporator 6 to control the flow rate and flow of the refrigerant. This design can improve the heat exchange efficiency and reduce energy loss.

[0042] In summary, the utility model designs an energy-saving dehumidifier, whose working principle is based on the thermodynamic principle of condensation and evaporation. The entire dehumidification process is achieved through the cooperation of a series of carefully designed components. First, after the air enters the dehumidifier, it is pre-cooled by the first condensation water heat exchanger. The main function of the first condensation water heat exchanger is to pre-cool the air first and improve the condensation efficiency of the water in the subsequent evaporator. At the same time, the cold released by the condensed water in the first condensation water heat exchanger is also absorbed by the air, achieving preliminary dehumidification. Then, the pre-cooled air enters the evaporator and exchanges heat with the refrigerant. Due to the effect of precooling, the moisture in the air is more likely to condense into water droplets and exchange heat with the refrigerant. In this way, the moisture is condensed and converted into water droplets, achieving more thorough dehumidification. Behind the evaporator, the supercooler is arranged between the second condensation water heat exchanger and the evaporator. This layout produces a gradual heat exchange process, and the incremental heat exchange improves the heat exchange efficiency and reduces energy loss. The subcooler is used to cool the refrigerant liquid and supercool it, disconnecting the fin heat bridge between the condenser 2 and the subcooler 4, and improving the supercooling degree of the refrigerant liquid at the end of the subcooler. Finally, the refrigerant enters the condenser from the evaporator and releases heat. The function of the condenser is to transfer the heat released by the refrigerant from the evaporator to the external environment and maintain a certain temperature of the treated air. The fan installed behind the condenser promotes the transfer and discharge of heat by increasing the air flow and improving the heat dissipation effect. In the whole working process, the flow and circulation of condensed water play an important role. A water receiving tray and a water tank group are provided at the bottom of the evaporator. The water receiving tray is connected to the first water tank. The condensed water is collected in the water receiving tray and flows into the first water tank. The water pump transports the condensed water from the first water tank to the water inlet of the condensation water heat exchanger to realize the circulation and water supply of the condensed water, make full use of the coldness in the condensed water, and improve the working efficiency and stability of the system. In general, this condensation heat exchange dehumidifier can efficiently dehumidify and provide a refreshing and dry environment through a series of well-designed components and processes.
