Description

Technical Field

[0001] This invention relates to the technical field of dehumidification, and specifically provides a cooling dehumidification system. Background Technology

[0002] In the manufacturing process of some high-end products (such as lithium batteries), the air humidity requirements of the manufacturing environment are very high. It is necessary to ensure that the air humidity is below a certain standard. Therefore, a cooling and dehumidification system is required to dehumidify the factory.

[0003] Commonly used dehumidification systems include rotary dehumidifiers, surface coolers, and heaters. A rotary dehumidifier consists of a rotor, a dehumidification channel, and a regeneration channel. Part of the rotor is located within the dehumidification channel, and another part within the regeneration channel. The rotor rotates continuously. The surface cooler is located on the air inlet side of the dehumidification channel to lower the air temperature. As the air temperature decreases, water vapor in the air condenses and is absorbed by the rotor, thus reducing the humidity of the air after passing through the rotor. As the rotor rotates, the areas with higher humidity rotate into the regeneration channel. The heater is located on the air inlet side of the regeneration channel to increase the air temperature. The high-temperature air, after passing through the rotor, causes the absorbed moisture to evaporate and be carried out of the rotor, thus drying and regenerating it. As the rotor rotates, the dried portion of the rotor enters the dehumidification channel for repeated dehumidification, and this cycle continues.

[0004] The drawback of the above technology is that both the surface cooler and the heater of the cooling and dehumidification system require energy consumption, resulting in low energy efficiency. Summary of the Invention

The dehumidification channel of the first rotary dehumidifier is connected to the dehumidification channel of the second rotary dehumidifier, and the regeneration channel of the second rotary dehumidifier is connected to the regeneration channel of the first rotary dehumidifier.

[0014] In a specific embodiment of the above-mentioned cooling and dehumidification system, the dehumidification channel of the first rotary dehumidifier is connected in series with the dehumidification channel of the second rotary dehumidifier, and the regeneration channel of the first rotary dehumidifier is connected in series or in parallel with the regeneration channel of the second rotary dehumidifier.

[0028] Example 1

[0029] To address the problem of low energy efficiency in existing cooling and dehumidification systems, this invention provides a cooling and dehumidification system, including a rotary dehumidifier and a heat pump unit.

[0030] like Figure 1 or Figure 2As shown, the rotary dehumidifier 0 includes a rotor 01, a dehumidification channel 02, and a regeneration channel 03. A portion of the rotor 01 is located within the dehumidification channel 02, and the other portion is located within the regeneration channel 03. The rotor 01 can rotate continuously. The air flowing in the dehumidification channel 02 has a lower temperature, and water vapor in the air easily condenses and is absorbed by the rotor 01, thereby reducing the humidity of the air after passing through the rotor 01. The air flowing in the regeneration channel 03 has a higher temperature. After passing through the rotor 01, the high-temperature air causes the moisture absorbed by the rotor 01 to evaporate and be carried out of the rotor 01, thus drying and regenerating the rotor 01. As the rotor 01 rotates, the portion of the rotor 01 that has undergone regeneration and drying enters the dehumidification channel 02 for renewed dehumidification, and this cycle repeats continuously.

[0031] The dehumidification channel 02 is divided into an inlet side and an outlet side, with the impeller 01 as the boundary, according to the air flow direction. The inlet side of the dehumidification channel 02 is generally equipped with cooling to lower the air temperature, so that the air can condense at the impeller 01. The regeneration channel 03 is also divided into an inlet side and an outlet side, with the impeller 01 as the boundary, according to the air flow direction. The inlet side of the regeneration channel 03 is generally equipped with heating to raise the air temperature, so as to dry the impeller 01 and complete the regeneration.

[0032] Part of the air flowing out from the dehumidification duct 02 enters the room, while the excess air is either exhausted or enters the regeneration duct 03. The air inlet side of the regeneration duct 03 is connected to a return air duct to replenish air into the regeneration duct 03, preventing the air pressure on the air inlet side of the regeneration duct 03 from becoming too low.

[0033] A heat pump unit includes an evaporator, condenser, compressor, and expansion valve. These components are connected sequentially via piping, forming a circulation loop filled with refrigerant. The compressor compresses the low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gaseous refrigerant. The condenser liquefies this high-temperature, high-pressure gaseous refrigerant into a medium-temperature, medium-pressure liquid refrigerant, releasing heat to the outside. The liquid refrigerant then enters the expansion valve for throttling, and subsequently passes through the evaporator, absorbing heat and evaporating back into a gaseous state. It then re-enters the compressor for compression and pressurization, thus completing the cycle. During operation, the heat pump unit uses the refrigerant as a medium, and under the action of the compressor and expansion valve, releases the heat absorbed by the evaporator at the condenser.

[0034] The heat pump unit includes a first heat pump unit 3. The first heat pump unit 3 includes a first evaporator 31, a first condenser 32, and a matching compressor and expansion valve. The first evaporator 31 is located on the air inlet side of the dehumidification channel 02. During operation, the first evaporator 31 absorbs heat from the air flowing through it, reducing the temperature of the air flowing towards the rotor 01 and improving its dehumidification effect. The heat absorbed by the first evaporator 31 is released at the first condenser 32 under the action of the compressor and expansion valve. The heat released by the first condenser 32 is then used to heat the air on the air inlet side of the regeneration channel 03, further improving the regeneration effect of the rotor 01. Overall, the first heat pump unit 3 can use the heat absorbed in the dehumidification channel 02 to heat the air in the regeneration channel 03, simultaneously achieving cooling and heating, which greatly improves energy efficiency and reduces the energy consumption of the cooling and dehumidification system.

[0035] If the power of the first heat pump unit 3 is insufficient to reduce the air blown towards the rotor 01 to a suitable temperature, a surface cooler 8 needs to be installed on the air inlet side of the dehumidification channel 02 to work together to reduce the air blown towards the rotor 01 to a suitable temperature. Cooler water flows through the surface cooler 8 to cool the air flowing through it.

[0036] In some implementations, such as Figure 1 As shown, the first condenser 32 is located on the air inlet side of the regeneration channel 03. The heat released by the first condenser 32 can be directly used to heat the air on the air inlet side of the regeneration channel 03.

[0037] In other implementations, such as Figure 2As shown, the heat released by the first condenser 32 is used to indirectly heat the air on the air inlet side of the regeneration channel 03. Specifically, the cooling and dehumidification system also includes a heat storage device 7, which contains a heat storage medium. In this embodiment, the heat storage medium is specifically water, but other liquids with a high specific heat capacity can also be used. The first condenser 32 can heat the heat storage medium in the heat storage device 7. The heat pump unit also includes a second heat pump unit 4 and a third heat pump unit 5. The second heat pump unit 4 includes a second evaporator 41, a second condenser 42, and a matching compressor and expansion valve. The third heat pump unit 5 includes a third evaporator 51, a third condenser 52, and a matching compressor and expansion valve. Both the second evaporator 41 and the third evaporator 51 can absorb heat from the heat storage medium. The second condenser 42 and the third condenser 52 are located on the air inlet side of the regeneration channel 03 to release heat to heat the air on the air inlet side of the regeneration channel 03, helping the rotor 01 to complete regeneration. The heat storage device 7 can absorb and store heat, and can play a buffering role. Even if the operating conditions of the cooling and dehumidification system change, causing the heat released by the first condenser 32 to decrease or even stop, the heat stored in the heat storage device 7 can also stably supply heat to the second condenser 42 and the third condenser 52 to heat the air on the air inlet side of the regeneration channel 03, ensuring that the rotor 01 can be regenerated after removing moisture.

[0038] Regarding the second heat pump unit 4 and the third heat pump unit 5, it should be noted that although in this embodiment, two sets of heat pump units (i.e., the second heat pump unit 4 and the third heat pump unit 5) are used to absorb heat from the heat storage device 7 to heat the air on the air inlet side of the regeneration channel 03, this is not a specific limitation of the present invention. Without departing from the principle of the present invention, in other embodiments, those skilled in the art can set one or more sets of heat pump units to absorb heat from the heat storage device 7 to heat the air on the air inlet side of the regeneration channel 03 to help the rotor 01 complete regeneration.

[0039] In some other embodiments, the heat pump unit further includes a fourth heat pump unit 6, which includes a fourth evaporator 61, a fourth condenser 62, and a matching compressor and expansion valve. The fourth evaporator 61 is located on the air outlet side of the regeneration channel 03, and the fourth condenser 62 is located on the air inlet side of the regeneration channel 03. The fourth evaporator 61 can absorb the waste heat of the air discharged from the air outlet side of the regeneration channel 03, and the absorbed heat is released at the fourth condenser 62 to heat the temperature of the air on the air inlet side of the regeneration channel 03, thereby improving energy utilization. Specifically, through the heat absorption effect of the fourth evaporator 61, the temperature of the air flowing through the fourth evaporator 61 can be reduced by about 50°C.

[0040] Furthermore, the fourth condenser 62, the second condenser 42, and the third condenser 52 are arranged sequentially along the airflow direction. Specifically, the air temperature at the inlet of the regeneration channel 03 is approximately 45°C. After being heated by the fourth condenser 62, it reaches approximately 70°C; after being heated by the second condenser 42, it reaches approximately 95°C; and after being heated by the third condenser 52, it reaches approximately 120°C. This hot air at approximately 120°C is blown onto the rotor 01, enabling the rotor 01 to complete regeneration. By utilizing a multi-stage heating method, the air can be heated through multiple stages with equal temperature differences, thereby improving heating efficiency and energy efficiency.

[0041] The first heat pump unit 3 and the fourth heat pump unit 6 are medium-temperature heat pump units, using R134a refrigerant as the refrigerant. The second heat pump unit 4 and the third heat pump unit 5 are high-temperature heat pump units, using R245fa refrigerant as the refrigerant. The distinction between medium-temperature and high-temperature heat pump units is based on the heating temperature of the condenser, and specific industry standards have been established in this field, which will not be elaborated upon further in this invention.

[0042] The compressors used in the first heat pump unit 3, the second heat pump unit 4, the third heat pump unit 5, and the fourth heat pump unit 6 are variable frequency compressors. By precisely controlling the operating frequency of the compressors in each heat pump unit, the fourth condenser 62, the second condenser 42, and the third condenser 52 can be distributed in a stepped temperature difference manner, thereby maximizing the energy efficiency of the heat pump units. Furthermore, if the dehumidification capacity of the rotor 01 is small, the temperature of the air blown onto the rotor 01 can be less than 120°C. In this case, one of the second heat pump unit 4, the third heat pump unit 5, and the fourth heat pump unit 6 can be turned off to reduce the temperature of the air blown onto the rotor 01 and lower energy consumption.

[0043] In summary, the working principle of this invention is as follows:

[0044] The first evaporator 31 absorbs heat from the air flowing through it, lowering the temperature of the air flowing towards the rotor 01 and causing moisture in the air to condense at the rotor 01, thus improving the dehumidification effect of the rotor 01. The dehumidified air then enters the room. The heat absorbed by the first evaporator 31 is released at the first condenser 32 to heat the heat storage medium in the heat storage device 7. The second evaporator 41 and the third evaporator 51 both absorb heat from the heat storage medium and release it at the second condenser 42 and the third condenser 52 to heat the air on the inlet side of the regeneration channel 03. Additionally, the fourth evaporator 61 absorbs the residual heat from the air discharged from the outlet side of the regeneration channel 03 and releases the absorbed heat at the fourth condenser 62 to heat the air on the inlet side of the regeneration channel 03. The fourth condenser 62, the second condenser 42, and the third condenser 52 are distributed in a stepped temperature gradient, heating the regeneration air blown towards the rotor 01 in stages. Among them, the first heat pump unit 3, the second heat pump unit 4, the third heat pump unit 5 and the fourth heat pump unit 6 are mainly used to transfer heat. They transfer the heat absorbed by the dehumidification channel 02 for cooling and the waste heat on the air outlet side of the regeneration channel 03 to heat the air on the air inlet side of the regeneration channel 03, thereby improving the energy efficiency of the cooling and dehumidification system.

[0045] Compared to traditional cooling and dehumidification systems that use chilled water for cooling in the dehumidification channel 02 and electric heating or boiler heating in the regeneration channel 03, this invention utilizes the synergistic effect of the first heat pump unit 3, the second heat pump unit 4, and the third heat pump unit 5 to simultaneously cool in the dehumidification channel 02 and heat in the regeneration channel 03. This allows the regeneration air blown towards the rotor 01 to be heated to 120°C without the need for additional heating equipment, greatly improving energy efficiency.

The structures of the first rotary dehumidifier 1 and the second rotary dehumidifier 2 are the same as those of the rotary dehumidifier 0 in Embodiment 1. The dehumidification channel 02 of the first rotary dehumidifier 1 is connected to the dehumidification channel 02 of the second rotary dehumidifier 2, and the regeneration channel 03 of the second rotary dehumidifier 2 is connected to the regeneration channel 03 of the first rotary dehumidifier 1.

[0048] Specifically, the dehumidification channel 02 of the first rotary dehumidifier 1 is connected in series with the dehumidification channel 02 of the second rotary dehumidifier 2, meaning the outlet side of the dehumidification channel 02 of the first rotary dehumidifier 1 is connected to the inlet side of the dehumidification channel 02 of the second rotary dehumidifier 2. The regeneration channel 03 of the second rotary dehumidifier 2 is connected in series with the regeneration channel 03 of the first rotary dehumidifier 1, meaning the outlet side of the regeneration channel 03 of the second rotary dehumidifier 2 is connected to the inlet side of the regeneration channel 03 of the first rotary dehumidifier 1. In this way, the hot air from the outlet side of the regeneration channel 03 of the second rotary dehumidifier 2 can also be utilized by the first rotary dehumidifier 1, resulting in higher energy efficiency.

[0049] The first rotary dehumidifier 1 has a surface cooler 8 installed on the air inlet side of the dehumidification channel 02. Flowing chilled water flows through the surface cooler 8 to cool the air flowing through it.

[0050] This invention also includes a first heat pump unit 3, a second heat pump unit 4, a third heat pump unit 5, and a fourth heat pump unit 6 as described in Embodiment 1. A first evaporator 31 is disposed on the air inlet side of the dehumidification channel 02 of the second rotary dehumidifier 2. A fourth evaporator 61 is disposed on the air outlet side of the regeneration channel 03 of the first rotary dehumidifier 1 to absorb waste heat from the air outlet side of the regeneration channel 03. A fourth condenser 62 is disposed on the air inlet side of the regeneration channel 03 of the first rotary dehumidifier 1.

[0051] Both the second heat pump unit 4 and the third heat pump unit 5 are equipped with two sets of two condensers. The two second condensers 42 are respectively located on the air inlet side of the regeneration channel 03 of the first rotary dehumidifier 1 and the air inlet side of the regeneration channel 03 of the second rotary dehumidifier 2. The two third condensers 52 are respectively located on the air inlet side of the regeneration channel 03 of the first rotary dehumidifier 1 and the air inlet side of the regeneration channel 03 of the second rotary dehumidifier 2, so as to ensure that the temperature of the regeneration air of the first rotary dehumidifier 1 and the second rotary dehumidifier 2 meets the requirements.

[0052] Regarding the fourth heat pump unit 6, it should be noted that although only one set of the fourth heat pump unit 6 is provided in this embodiment of the invention, this is not a specific limitation of the invention. Without departing from the principle of the invention, in other embodiments, two sets of the fourth heat pump unit 6 can be provided. The fourth evaporator 61 of both sets of the fourth heat pump unit 6 is provided on the air outlet side of the regeneration channel 03 of the first rotary dehumidifier 1, and the fourth condenser 62 of the two sets of the fourth heat pump unit 6 is provided on the air inlet side of the regeneration channel 03 of the first rotary dehumidifier 1 and the air inlet side of the regeneration channel 03 of the second rotary dehumidifier 2, respectively.

[0053] Of course, without departing from the principles of the present invention, in other embodiments, those skilled in the art can also connect the dehumidification channel 02 of the first rotary dehumidifier 1 in parallel with the dehumidification channel 02 of the second rotary dehumidifier 2, and / or connect the regeneration channel 03 of the second rotary dehumidifier 2 in parallel with the regeneration channel 03 of the first rotary dehumidifier 1. After the dehumidification channel 02 of the first rotary dehumidifier 1 and the dehumidification channel 02 of the second rotary dehumidifier 2 are connected in parallel, the first heat pump unit 3 and the surface cooler can be set before the parallel section to simultaneously cool the air entering the dehumidification channel 02 of the first rotary dehumidifier 1 and the dehumidification channel 02 of the second rotary dehumidifier 2. After the regeneration channel 03 of the second rotary dehumidifier 2 is connected in parallel with the regeneration channel 03 of the first rotary dehumidifier 1, the second heat pump unit 4, the third heat pump unit 5 and the fourth heat pump unit 6 can be set before the parallel section to heat the air entering the regeneration channel 03 of the second rotary dehumidifier 2 and the regeneration channel 03 of the first rotary dehumidifier 1.

However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments.
