Description

Technical Field

[0001] This invention relates to the field of refrigeration and dehumidification equipment, and in particular to an integrated solution dehumidification unit with independent temperature and humidity control. Background Technology

[0002] Solution dehumidifiers have a wide range of applications. Traditional solution dehumidifiers typically use highly hygroscopic solutions, such as lithium bromide, lithium chloride, and calcium chloride, to dry the gas being treated, thereby reducing its humidity. After absorbing water vapor from the gas, the moisture enters the solution, causing the solution concentration to decrease, the vapor pressure to rise, and the ability to absorb water vapor to decrease, thus failing to dry the gas. To maintain the solution concentration, regeneration measures are usually required after the water vapor concentration decreases, increasing the concentration and discharging the moisture. However, solution dehumidifiers are not only used in conjunction with other air conditioning equipment; sometimes they independently perform the functions of cooling, dehumidifying, heating, and humidifying a space. Therefore, providing an integrated solution dehumidifier with independent temperature and humidity control that can independently achieve the functions of cooling, dehumidifying, heating, and humidifying, and independently control the temperature and humidity of a space, has become an urgent problem to be solved.

The dehumidifying fan 2 is installed at the air inlet of the dehumidifying box 1; Dehumidifying filler 3 is installed inside dehumidifying box 1; Dehumidifier sprayer 18 is installed above dehumidifier packing 3; The regeneration mechanism includes a regeneration box 15, a regeneration fan 16, a regeneration packing material 14, and a regeneration sprayer 17; The regeneration box 15 is equipped with an air inlet and an air outlet. The regeneration fan 16 is installed at the air inlet of the regeneration box 15; The recycled packing 14 is installed inside the recycling box 15; The regeneration sprayer 17 is installed above the regeneration packing material 14; The cooling mechanism includes an evaporator 6, a condenser 11, a first brazed plate heat exchanger 26, a second brazed plate heat exchanger 30, a two-way expansion valve 8, a dryer filter 9, a four-way reversing valve 34, and a compressor 33. The outlet of compressor 33 is connected in sequence via pipeline to the second brazed plate heat exchanger 30, the inlet of the four-way reversing valve 34, the condenser 11, the dryer filter 9, the two-way expansion valve 8, the evaporator 6, the outlet of the four-way reversing valve 34, the first brazed plate heat exchanger 26, and the inlet of compressor 33. The first brazed plate heat exchanger 26 is installed on the low-pressure pipeline between the inlet of the compressor 33 and the outlet of the four-way reversing valve 34, and the first brazed plate heat exchanger 26 is used for refrigeration. The second brazed plate heat exchanger 30 is installed on the high-pressure pipeline between the outlet of the compressor 33 and the inlet of the four-way reversing valve 34, and the second brazed plate heat exchanger 30 is used for heating. The temperature control mechanism includes a cooling coil 19, a heating coil 20, a first three-way valve 25, a second three-way valve 32, a heating pump 27, and a cooling pump 24. The cooling coil 19 and the heating coil 20 are both installed at the air outlet of the dehumidification box 1; The outlet of the refrigeration coil 19 is connected to the inlet of the first brazed plate heat exchanger 26 through the first refrigerant line 21. The outlet of the first brazed plate heat exchanger 26 is connected to the inlet of the refrigeration coil 19 through the second refrigerant line 23. A cooling pump 24 is installed on the first refrigerant line 21. The inlet of the heating coil 20 is connected to the inlet of the second brazed plate heat exchanger 30 through the first heat medium pipeline 28, and the outlet of the second brazed plate heat exchanger 30 is connected to the inlet of the heating coil 20 through the second heat medium pipeline 29. A heating pump 27 is installed on the first heat medium pipeline 28. A third refrigerant pipe 22 is connected between the first refrigerant pipe 21 and the second refrigerant pipe 23. A first three-way valve 25 is installed at the connection between the third refrigerant pipe 22 and the first refrigerant pipe 21. A third heat medium pipeline 31 is connected between the first heat medium pipeline 28 and the second heat medium pipeline 29. A second three-way valve 32 is installed at the connection between the third heat medium pipeline 31 and the first heat medium pipeline 28. In use, a second brazed plate heat exchanger is connected in series on the high-pressure pipeline from the outlet of compressor 33 to the inlet of four-way reversing valve 34. The second brazed plate heat exchanger only provides heat. A first brazed plate heat exchanger is connected in series on the low-pressure pipeline from the inlet of compressor 33 to the outlet of four-way reversing valve 34. The first brazed plate heat exchanger only provides cooling. Therefore, no matter how the four-way reversing valve 34 switches in the refrigeration system, it can always maintain a stable supply of heat and cooling to the heating coil and the cooling coil 19, so that the equipment can stably heat and cool down, which is beneficial to temperature control. When the four-way reversing valve 34 is in cooling mode, it provides cooling capacity to the evaporator 6, which cools down the solution in the dehumidification chamber 1. The low-temperature solution comes into contact with the air, which cools down and dehumidifies the air. At the same time, it provides heat to the condenser 11, which heats up the solution in the regeneration chamber 15. The high-temperature solution comes into contact with the air, which warms up and humidifies the air. When the four-way reversing valve 34 switches to the heating mode, the working principle is reversed. It provides heat to the evaporator 6, which raises the temperature of the solution in the dehumidification box 1. The high-temperature solution comes into contact with the air, which raises the temperature and humidifies the air. At the same time, it provides cooling to the condenser 11, which lowers the temperature of the solution in the regeneration box 15. The low-temperature solution comes into contact with the air, which lowers the temperature and dehumidifies the air. This application utilizes a single compressor 33 to achieve four different functions: dehumidification, humidification, heating, and cooling of air, enabling more efficient control of temperature and humidity. When the four-way reversing valve 34 is switched to cooling mode, it can achieve cooling and dehumidification of the air. When the four-way reversing valve 34 is switched to heating mode, it can achieve heating and humidification of the air. When the electric three-way valve 2 is opened, it can achieve heating of the air. When the electric first three-way valve 25 is opened, it can achieve cooling of the air. When the electric second three-way valve 32 is opened, it can achieve heating of the air. Thus, it provides an integrated temperature and humidity independent control solution dehumidifier unit that can independently achieve the cooling, dehumidification, heating, and humidification functions of the unit and independently complete the temperature and humidity control of a space.

[0012] In this application, the first three-way valve 25 and the second three-way valve 32 are not allowed to be opened simultaneously to avoid the cancellation of hot and cold and unstable control.

[0013] In this embodiment, the bottom of the dehumidification box 1 is connected to a first conveying pipe 5, which is sequentially connected to a dehumidification pump 4, an evaporator 6, and a dehumidification sprayer 18; the bottom of the regeneration box 15 is connected to a second conveying pipe 13, which is sequentially connected to a regeneration pump 12, a condenser 11, and a regeneration sprayer 17; one end of a third conveying pipe 7 is connected to the first conveying pipe 5, and the other end of the third conveying pipe 7 is connected to the bottom of the regeneration box 15; one end of a fourth conveying pipe 10 is connected to the second conveying pipe 13, and the other end of the fourth conveying pipe 10 is connected to the bottom of the dehumidification box 1. With the third conveying pipe 7 and the fourth conveying pipe 10 interconnected, the solution in the dehumidification box 1 and the solution in the regeneration box 15 are interconnected. The flow rate of the interconnection can be adjusted by the valve, so that the concentrated solution and the dilute solution can continuously circulate with each other, maintaining the continuous dehumidification or humidification function of the equipment.

[0014] In this embodiment, the first refrigerant pipe 21 and the second refrigerant pipe 23 are connected by a third refrigerant pipe 22, and a first three-way valve 25 is installed at the connection between the third refrigerant pipe 22 and the first refrigerant pipe 21.

[0015] In this embodiment, a third heat medium pipeline 31 connects the first heat medium pipeline 28 and the second heat medium pipeline 29. A second three-way valve 32 is installed at the connection between the third heat medium pipeline 31 and the first heat medium pipeline 28.

[0016] In this embodiment, both the dehumidifying packing 3 and the regenerating packing 14 are wet curtains.

[0017] In this application, the dehumidification and humidification functions are mainly achieved by switching the four-way reversing valve 34. When the equipment needs dehumidification, the four-way reversing valve 34 is used normally, and the evaporator 6 provides cooling capacity to the dehumidification box 1 to achieve cooling and dehumidification of the air. When the equipment needs humidification, the four-way reversing valve 34 switches, and the original evaporator 6 becomes the condenser 11 to provide heat to the dehumidification box 1, so that the original dehumidification box 1 has heating and humidification functions. The selection of humidification and dehumidification functions is based on comparing the humidity set by the customer with the actual humidity and making a certain hysteresis value to avoid frequent switching between dehumidification and humidification functions.

[0018] This application achieves the cooling function using a refrigeration coil 19, a cooling pump 24, and a second three-way valve 32. After the compressor 33 is turned on, the second brazed plate heat exchanger 30 will continuously provide cooling. During normal operation, the cooling pump 24 will run continuously. The equipment automatically compares the customer-set temperature with the actual temperature. If cooling is not required, the second three-way valve 32 will open the bypass, and the circulating liquid will not pass through the second plate heat exchanger, thus preventing the cooling capacity of the second plate heat exchanger from being carried into the chilled water coil and released into the air. If cooling is required, the second three-way valve 32 will close the bypass, and the circulating liquid will pass through or partially pass through the second brazed plate heat exchanger 30, carrying the cooling capacity to the refrigeration coil 19 and releasing it into the air, thereby lowering the air temperature.

[0019] This application achieves the heating function using a heating coil 20, a heating pump 27, and a first three-way valve 25. After the compressor 33 is turned on, the first brazed plate heat exchanger 26 will continuously provide heat. During normal operation, the heating pump 27 will run continuously. The equipment automatically compares the customer-set temperature with the actual temperature. If heating is not required: the first three-way valve 25 will open the bypass, and the circulating liquid will not pass through the first brazed plate heat exchanger 26, thus preventing the heat from the first brazed plate heat exchanger 26 from being carried to the heating coil 20 and released into the air. If heating is required: the first three-way valve 25 will close the bypass, and the circulating liquid will pass through or partially pass through the first brazed plate heat exchanger 26, carrying the heat to the cooling coil 19 and releasing it into the air, thus raising the air temperature.

[0020] Heating and cooling are mutually exclusive, avoiding simultaneous heating and cooling, thus neutralizing the cold and heat. Both the first three-way valve 25 and the second three-way valve 32 use analog flow control, which can accurately control the temperature according to actual needs. The temperature control also reduces the temperature hysteresis, avoiding frequent switching between heating and cooling modes, which can lead to unstable control.

[0021] The working principle of this invention is as follows: This application utilizes a single compressor 33 to achieve four different functions: dehumidification, humidification, heating, and cooling of air, enabling more efficient control of temperature and humidity. When the four-way reversing valve 34 is switched to cooling mode, it can achieve cooling and dehumidification of the air. When the four-way reversing valve 34 is switched to heating mode, it can achieve heating and humidification of the air. When the electric three-way valve 2 is opened, it can achieve heating of the air. When the electric first three-way valve 25 is opened, it can achieve cooling of the air. When the electric second three-way valve 32 is opened, it can achieve heating of the air. Thus, it provides an integrated temperature and humidity independent control solution dehumidifier unit that can independently achieve the cooling, dehumidification, heating, and humidification functions of the unit and independently complete the temperature and humidity control of a space.
