Technical Field

[0001] This invention relates to the field of air conditioning technology, and in particular to a humidity control device, humidity control method, apparatus and storage medium thereof. Background Technology

[0002] Humidity control equipment can adjust air humidity using absorbent materials capable of absorbing and desorbing moisture, and a heat pump can be installed as a regeneration heat source for these absorbent materials. The refrigerant circuit of a heat pump typically includes an expansion valve to adjust the refrigerant temperature and flow rate in the evaporator. However, the problem is that when the refrigerant temperature required by the absorbent material in the condenser is lower than the regeneration temperature, the desorption of moisture by the absorbent material will be incomplete. This leads to decreased dehumidification performance during cooling and decreased humidification performance during heating.

[0003] In related technologies, existing refrigerant circuits are used, and the refrigerant flow is increased by increasing the compressor speed. However, increasing the compressor speed will lead to a significant increase in the compressor's power consumption. Summary of the Invention

[0009] The humidity control method of the humidity control device according to an embodiment of the present invention obtains the refrigerant saturation temperature at the compressor discharge port and controls the first and second throttling elements according to the refrigerant saturation temperature to adjust the humidity control capability of the humidity control element. This effectively controls the refrigerant temperature of the condenser, improves the humidity control capability of the humidity control element, and suppresses the increase in compressor power consumption.

[0010] According to one embodiment of the present invention, obtaining the refrigerant saturation temperature at the compressor discharge port includes: obtaining the refrigerant pressure at the compressor discharge port; and obtaining the refrigerant saturation temperature based on the refrigerant pressure.

[0033] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The following description, with reference to the accompanying drawings, describes the humidity control equipment, humidity control method, humidity control device, and computer-readable storage medium provided by the embodiments of the present invention.

[0034] It should be noted that humidity control equipment can adjust air humidity using absorbent materials capable of absorbing and desorbing moisture. In actual operation, outdoor air is drawn in; during cooling mode, the absorbent material dehumidifies, and during heating mode, it humidifies, supplying fresh air with moderate humidity to the room. A heat pump is typically installed as the regeneration heat source for the absorbent material. The refrigerant circuit of the heat pump has an expansion valve to adjust the refrigerant temperature and flow rate of the evaporator, but not an expansion valve to adjust the refrigerant temperature and flow rate of the condenser. This causes the refrigerant pressure and temperature of the condenser to tend towards operation; if the refrigerant temperature of the condenser required by the absorbent material is lower than the regeneration temperature, the desorption of moisture by the absorbent material will be incomplete. This leads to decreased dehumidification performance during cooling and decreased humidification performance during heating. Related technologies still use existing refrigerant circuits, simply increasing the compressor speed to increase the refrigerant flow rate. However, increasing the compressor speed leads to a significant increase in the compressor's power consumption.

[0035] Based on this, this application provides a humidity control method for a humidity control device. This method adjusts the condensing pressure and refrigerant saturation temperature, thereby enabling the humidity control component to fully decompose and absorb water, suppressing the decline in dehumidification and humidification performance, effectively improving the humidity control capability of the humidity control component, and suppressing the increase in compressor power consumption.

[0036] Figure 1 A schematic diagram of the refrigeration mode operation of a humidity control device according to an embodiment of the present invention is shown. Figure 2 for Figure 1 A schematic diagram of the heating mode operation of the medium-temperature humidification equipment is provided for reference. Figure 1-2As shown, the humidity control device 100 includes a humidity control component 101 and a refrigerant circuit. The humidity control component 101 can be a rotor-shaped absorbent material. The refrigerant circuit is formed by sequentially connecting a compressor 102, a first heat exchanger 103, a regulating component, and a second heat exchanger 104. The regulating component includes a first throttling component 105, a receiver 106, and a second throttling component 107. One end of the first throttling component 105 is connected to the first heat exchanger 103, and its other end is connected to one end of the receiver 106. One end of the second throttling component 107 is connected to the second heat exchanger 104, and its other end is connected to the other end of the receiver 106. The humidity control component 101 is configured corresponding to the first heat exchanger 103 and the second heat exchanger 104. Because the humidity regulating element 101 has the ability to adsorb water vapor from the air and is configured corresponding to the first heat exchanger 103 and the second heat exchanger 104, it can adsorb water vapor from indoor and outdoor air. A portion of the humidity regulating element 101 corresponding to the first heat exchanger 103 can release water vapor outdoors, and a portion of the humidity regulating element 101 corresponding to the second heat exchanger 104 can release water vapor indoors. When the humidity regulating equipment is running, the condenser in the refrigerant circuit heats the corresponding portion of the humidity regulating element 101, causing the adsorbed water vapor to dissipate. When the first heat exchanger 103 is a condenser, the water vapor is discharged outdoors, achieving dehumidification of the indoor air; when the second heat exchanger 104 is a condenser, the water vapor is discharged indoors, achieving humidification of the indoor air.

[0037] It should be noted that in the first heat exchanger 103 and the second heat exchanger 104, one is an evaporator and the other is a condenser; the first throttling element 105 can be an expansion valve capable of adjusting the refrigerant temperature and flow rate of the first heat exchanger 103, and the second throttling element 107 can be an expansion valve capable of adjusting the refrigerant temperature and flow rate of the second heat exchanger 104. This humidity control device structure, combined with appropriate humidity control methods, can control the refrigerant temperature of the two heat exchangers, enabling the humidity control elements to fully perform water decomposition and absorption, suppressing the decline in dehumidification and humidification performance, improving the humidity control capacity of the humidity control elements, and suppressing the increase in compressor power consumption.

[0038] Figure 3 A flowchart of a humidity control method for a humidity control device according to an embodiment of the present invention is provided. Figure 3 As shown, the humidity control method of this humidity control equipment may include the following steps:

[0039] Step S201: Obtain the refrigerant saturation temperature at the compressor discharge port.

[0040] This step may specifically include: obtaining the refrigerant pressure at the compressor discharge port; and obtaining the refrigerant saturation temperature based on the refrigerant pressure. Specifically, for example... Figure 1 and Figure 2As shown, a high-pressure sensor 108 can be installed at the compressor outlet to detect the refrigerant pressure at the compressor discharge port. This refrigerant pressure is the refrigerant pressure of the condenser, and the corresponding refrigerant saturation temperature can be calculated based on this refrigerant pressure.

[0041] Step S202: Control the first and second throttling elements according to the refrigerant saturation temperature to adjust the humidity control capacity of the humidity control element.

[0042] In other words, after obtaining the refrigerant saturation temperature, the opening of the two throttling devices can be controlled according to the refrigerant saturation temperature to control the amount of refrigerant in the corresponding heat exchanger, thereby adjusting the condensing pressure and refrigerant saturation temperature. This allows the humidity control device to fully decompose and absorb water, suppressing the decline in dehumidification and humidification performance, improving the humidity control capability of the humidity control device, and suppressing the increase in compressor power consumption.

[0043] In one embodiment, controlling the first throttling element and the second throttling element based on the refrigerant saturation temperature includes: obtaining the current operating mode of the humidity control device; if the operating mode is a cooling mode, controlling the first throttling element based on the refrigerant saturation temperature; if the operating mode is a heating mode, controlling the second throttling element based on the refrigerant saturation temperature.

[0044] Specifically, such as Figure 1 and Figure 2 As shown, the humidity control device 100 can operate in both cooling and heating modes by using a four-way valve 109. When controlling the two throttling devices based on the refrigerant saturation temperature, the current operating mode can be obtained first: when the humidity control device 100 is operating in cooling mode, refer to... Figure 1 As shown, the first heat exchanger 103 can be connected to the compressor 102 via a four-way valve 109, and the second heat exchanger 104 can be connected to the gas-liquid separator 110 via a four-way valve 109, so that the first heat exchanger 103 acts as a condenser and the second heat exchanger 104 acts as an evaporator. During operation, the first heat exchanger 103 releases heat as a condenser, and the corresponding portion of the humidity-regulating element 101 in the first heat exchanger 103 is heated, causing the adsorbed water vapor to be released outdoors, reducing indoor humidity. Simultaneously, the refrigerant saturation temperature is calculated based on the refrigerant pressure at the compressor discharge port, and the opening of the first throttling element 105 is controlled to control the amount of refrigerant in the condenser, thereby improving the humidity-regulating capacity and controlling the adjustment of indoor humidity. When the humidity-regulating device 100 operates in heating mode, refer to... Figure 2As shown, the first heat exchanger 103 is connected to the gas-liquid separator 110 via a four-way valve 109, and the second heat exchanger 104 is connected to the compressor 102 via a four-way valve 109, so that the first heat exchanger 103 is an evaporator and the second heat exchanger 104 is a condenser. During operation, the second heat exchanger 104 acts as a condenser, and the corresponding part of the humidity regulating element 101 of the second heat exchanger 104 is heated, causing the adsorbed water vapor to be released into the room, thereby increasing the indoor humidity. At the same time, the refrigerant saturation temperature is calculated based on the refrigerant pressure at the compressor discharge port, and the opening of the second throttling element 107 is controlled to control the amount of refrigerant in the condenser, thereby improving the humidity regulating capacity and controlling the indoor humidity adjustment.

[0045] Optionally, the first throttling element is controlled according to the refrigerant saturation temperature, including: if the refrigerant saturation temperature is less than the regeneration temperature of the humidity regulating element, the opening of the first throttling element is reduced; if the refrigerant saturation temperature is equal to the regeneration temperature of the humidity regulating element, the opening of the first throttling element is kept unchanged; if the refrigerant saturation temperature is greater than the regeneration temperature of the humidity regulating element, the opening of the first throttling element is increased.

[0046] In other words, when the humidity control equipment is operating in cooling mode, the opening of the first throttling element is controlled according to the refrigerant saturation temperature. Specifically, when the refrigerant saturation temperature is lower than the regeneration temperature of the humidity control element, the opening of the first throttling element is reduced. At this time, the liquid refrigerant in the first heat exchanger increases, while the two-phase refrigerant decreases, reducing the condenser's condensing capacity. This causes the condensing pressure and refrigerant saturation temperature to rise, thus reducing the temperature difference between the absorbent material and the target regeneration temperature of the humidity control element, effectively improving the humidity control capability. When the refrigerant saturation temperature is higher than the regeneration temperature of the humidity control element, the opening of the first throttling element is increased. At this time, the liquid refrigerant in the first heat exchanger decreases, while the two-phase refrigerant increases, increasing the condenser's condensing capacity. This causes the condensing pressure and refrigerant saturation temperature to decrease, thus reducing the temperature difference between the absorbent material and the target regeneration temperature of the humidity control element, effectively improving the humidity control capability. When the refrigerant saturation temperature is within the regeneration temperature range of the humidity control element, the current opening of the first throttling element is maintained.

[0047] Optionally, the second throttling element is controlled according to the refrigerant saturation temperature, including: if the refrigerant saturation temperature is less than the regeneration temperature of the humidity regulating element, the opening of the second throttling element is reduced; if the refrigerant saturation temperature is equal to the regeneration temperature of the humidity regulating element, the opening of the second throttling element is kept unchanged; if the refrigerant saturation temperature is greater than the regeneration temperature of the humidity regulating element, the opening of the second throttling element is increased.

[0048] In other words, when the humidity control equipment is operating in heating mode, the opening of the second throttling element is controlled according to the refrigerant saturation temperature. Specifically, when the refrigerant saturation temperature is lower than the regeneration temperature of the humidity control element, the opening of the second throttling element is reduced. At this time, the liquid refrigerant in the second heat exchanger increases, while the two-phase refrigerant decreases, reducing the condenser's condensing capacity. This causes the condensing pressure and refrigerant saturation temperature to rise, thus reducing the temperature difference between the absorbent material and the target regeneration temperature of the humidity control element, effectively improving the humidity control capability of the humidity control element. When the refrigerant saturation temperature is higher than the regeneration temperature of the humidity control element, the opening of the second throttling element is increased. At this time, the liquid refrigerant in the second heat exchanger decreases, while the two-phase refrigerant increases, increasing the condenser's condensing capacity. This causes the condensing pressure and refrigerant saturation temperature to decrease, thus reducing the temperature difference between the absorbent material and the target regeneration temperature of the humidity control element, effectively improving the humidity control capability of the humidity control element. When the refrigerant saturation temperature is within the regeneration temperature range of the humidity control element, the current opening of the second throttling element is maintained.

[0049] In one embodiment, dehumidification is performed by a humidifier when operating in cooling mode; and humidification is performed by a humidifier when operating in heating mode.

[0050] In other words, because the humidity regulating element has the ability to adsorb water vapor from the air, when operating in cooling mode, the condenser of the refrigerant circuit transfers heat to the humidity regulating element. Upon heating, the adsorbed water vapor in the element is released and discharged outdoors, thus dehumidifying the indoor air. When operating in heating mode, the air heated by the condenser of the refrigerant circuit heats the humidity regulating element. Upon heating, the adsorbed water vapor in the element is released and discharged indoors, thus humidifying the indoor air. In a specific example, the humidity regulating element can be a ring-shaped adsorbent, which can be made of a renewable adsorbent material.

[0051] The present invention will be further explained and illustrated below through a specific embodiment.

[0052] Figure 4 A flowchart of a humidity control method for a humidity control device operating in cooling mode according to an embodiment of the present invention is provided. Figure 4 As shown, the humidity control method includes the following steps:

[0053] Step S301: Obtain the refrigerant pressure value through a high-pressure pressure sensor.

[0054] Step S302: Calculate the refrigerant saturation temperature based on the refrigerant pressure value.

[0055] Step S303: Determine whether the regeneration temperature of the humidity regulating element is greater than the refrigerant saturation temperature. If yes, reduce the opening of the first throttling element; otherwise, proceed to step S304.

[0056] Step S304: Determine whether the regeneration temperature of the humidity regulating element is lower than the refrigerant saturation temperature. If yes, increase the opening of the first throttling element; otherwise, maintain the opening of the first throttling element.

[0057] Figure 5 This is a flowchart of a humidification method for a humidification device operating in heating mode according to an embodiment of the present invention, with reference to... Figure 5 As shown, the humidity control method includes the following steps:

[0058] Step S401: Obtain the refrigerant pressure value through a high-pressure pressure sensor.

[0059] Step S402: Calculate the refrigerant saturation temperature based on the refrigerant pressure value.

[0060] Step S403: Determine whether the regeneration temperature of the humidity regulating element is greater than the refrigerant saturation temperature. If yes, reduce the opening of the second throttling element; otherwise, proceed to step S304.

[0061] Step S404: Determine whether the regeneration temperature of the humidity regulating element is lower than the refrigerant saturation temperature. If yes, increase the opening of the second throttling element; otherwise, maintain the opening of the second throttling element.

[0062] It should be understood that, although Figure 3-5 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order in which these steps are executed, and they can be performed in other orders. Furthermore, Figure 3-5 At least some of the steps in the process may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least some of the sub-steps or stages of other steps.

[0063] Figure 6 For a Morrill line diagram of the operating cooling mode of a humidification device according to related technologies and an embodiment of the present invention, refer to Figure 6 As shown, curve 1 is the Morrill line for the refrigeration mode of a humidity control device operating without auxiliary measures, i.e., when the refrigerant pressure and temperature of the condenser only tend towards operation; curve 2 is the Morrill line for the refrigeration mode of a humidity control device operating with increased compressor speed to increase refrigerant flow, as described in the related art; curve 3 is the Morrill line for the refrigeration mode of a humidity control device operating with its humidity control method according to an embodiment of the present invention. From Figure 6As can be seen from the data, compared with curve 1, the condensing pressure of curve 3 is significantly increased; compared with curve 2, the power consumption of the compressor in curve 3 is significantly reduced.

[0064] Figure 7 A compressor curve diagram showing the operation of a humidification device in cooling mode according to related technologies and an embodiment of the present invention. (Reference) Figure 7 As shown, curve 4 represents the change in regeneration temperature of the absorbent material of the dehumidifying element over time when the dehumidifying device is operating in cooling mode; curve 5 represents the change in refrigerant saturation temperature over time when the dehumidifying device is operating in cooling mode; curve 6 represents the change in compressor power consumption over time when the dehumidifying device is operating in cooling mode in related technologies; curve 7 represents the change in compressor power consumption over time when the dehumidifying device is operating in cooling mode according to an embodiment of the present invention; curve 8 represents the change in compressor speed over time when the dehumidifying device is operating in cooling mode in related technologies; and curve 9 represents the change in compressor speed over time when the dehumidifying device is operating in cooling mode according to an embodiment of the present invention. (Reference) Figure 7 As shown, comparing curves 6 and 7, and curves 8 and 9, it can be seen that when the refrigerant saturation temperature increases, the compressor speed in the related technologies significantly increases compared to the embodiments of the present invention. Both the increase in compressor speed and the increase in compression ratio (i.e., the ratio of discharge pressure to suction pressure) lead to an increase in compressor input. In contrast, using the embodiments of the present invention, since the compressor speed is not affected, the only factor affecting the increase in compressor input is the increase in compression ratio, not the increase in compressor speed. Therefore, compared to the related technologies, it can effectively reduce compressor input.

[0065] In summary, the humidity control method of the humidity control device according to the embodiments of the present invention obtains the refrigerant saturation temperature at the compressor discharge port and controls the first and second throttling elements according to the refrigerant saturation temperature to adjust the humidity control capability of the humidity control element. In this way, the refrigerant temperature of the condenser can be effectively controlled, the humidity control capability of the humidity control element can be improved, and the increase in compressor power consumption can be suppressed.

[0066] Figure 8 This is a structural block diagram of a humidity control device according to an embodiment of the present invention. (Reference) Figure 8As shown, the humidity control device includes a humidity control component and a refrigerant circuit. The refrigerant circuit is formed by sequentially connecting a compressor, a first heat exchanger, a regulating component, and a second heat exchanger. The regulating component includes a first throttling component, a second throttling component, and a receiver. One end of the first throttling component is connected to the first heat exchanger, and the other end is connected to one end of the receiver. One end of the second throttling component is connected to the second heat exchanger, and the other end is connected to the other end of the receiver. The humidity control component is configured corresponding to the first and second heat exchangers. Because the humidity control component 101 has the ability to adsorb water vapor in the air and is configured corresponding to the first heat exchanger 103 and the second heat exchanger 104, it can adsorb water vapor in the indoor and outdoor air. The air heated by the condenser of the refrigerant circuit heats the humidity control component. After being heated, the adsorbed water vapor in the humidity control component is released. When the water vapor is discharged to the outside, it can dehumidify the indoor air; when it is discharged into the room, it can humidify the indoor air.

[0067] It should be noted that in the first and second heat exchangers, one is an evaporator and the other is a condenser; the first throttling element can be an expansion valve that can adjust the refrigerant temperature and flow rate of the first heat exchanger, and the second throttling element can be an expansion valve that can adjust the refrigerant temperature and flow rate of the second heat exchanger. This humidity control equipment structure, combined with appropriate humidity control methods, can control the refrigerant temperature of the two heat exchangers, allowing the humidity control elements to fully perform water decomposition and absorption, suppressing the decline in dehumidification and humidification performance, improving the humidity control capacity of the humidity control elements, and suppressing the increase in compressor power consumption.

[0068] The humidity control device 500 of the humidity control equipment includes an acquisition module 501 and a control module 502. The acquisition module 501 acquires the refrigerant saturation temperature at the compressor discharge port; the control module 502 controls the first and second throttling elements based on the refrigerant saturation temperature to adjust the humidity control capacity of the humidity control unit. In other words, after acquiring the refrigerant saturation temperature, the control module 502 can control the opening degree of the two throttling elements based on this temperature to control the amount of refrigerant in the corresponding heat exchanger, thereby adjusting the corresponding condensing pressure and refrigerant saturation temperature. This allows the humidity control unit to fully decompose and absorb water, suppressing the decline in dehumidification and humidification performance, improving the humidity control capacity of the humidity control unit, and suppressing the increase in compressor power consumption.

[0069] In one embodiment, the acquisition module 501 is specifically used to: acquire the refrigerant pressure at the compressor discharge port; and acquire the refrigerant saturation temperature based on the refrigerant pressure. Specifically, the acquisition module 501 may include a high-pressure sensor, which can be installed at the compressor outlet to detect the refrigerant pressure at the compressor discharge port. This refrigerant pressure is the refrigerant pressure of the condenser. The acquisition module 501 can then calculate the corresponding refrigerant saturation temperature based on this refrigerant pressure.

[0070] In one embodiment, the control module 502 is specifically used to: obtain the current operating mode of the humidity control device; if the operating mode is cooling mode, control the first throttling element according to the refrigerant saturation temperature; if the operating mode is heating mode, control the second throttling element according to the refrigerant saturation temperature.

[0071] In one embodiment, the control module 502 is specifically used to: reduce the opening of the first throttling element if the refrigerant saturation temperature is less than the regeneration temperature of the humidifier; keep the opening of the first throttling element unchanged if the two are equal; and increase the opening of the first throttling element if the refrigerant saturation temperature is greater than the regeneration temperature of the humidifier. Specifically, when the refrigerant saturation temperature is lower than the regeneration temperature of the humidity conditioning element, the control module 502 controls the opening of the first throttling element to decrease. At this time, the liquid refrigerant in the first heat exchanger increases, while the two-phase refrigerant decreases, causing the condenser's condensing capacity to decrease. This leads to an increase in condensing pressure and refrigerant saturation temperature, thereby reducing the temperature difference between the absorbent material of the humidity conditioning element and the target regeneration temperature, effectively improving the humidity conditioning capacity of the humidity conditioning element. When the refrigerant saturation temperature is higher than the regeneration temperature of the humidity conditioning element, the control module 502 controls the opening of the first throttling element to increase. At this time, the liquid refrigerant in the first heat exchanger decreases, while the two-phase refrigerant increases, increasing the condenser's condensing capacity. This leads to a decrease in condensing pressure and refrigerant saturation temperature, thereby reducing the temperature difference between the absorbent material of the humidity conditioning element and the target regeneration temperature, effectively improving the humidity conditioning capacity of the humidity conditioning element. When the refrigerant saturation temperature is within the regeneration temperature range of the humidity conditioning element, the current opening of the first throttling element is maintained.

[0072] In one embodiment, the control module 502 is specifically used to: reduce the opening of the second throttling element if the refrigerant saturation temperature is less than the regeneration temperature of the humidity regulating element; keep the opening of the second throttling element unchanged if the refrigerant saturation temperature is equal to the regeneration temperature of the humidity regulating element; and increase the opening of the second throttling element if the refrigerant saturation temperature is greater than the regeneration temperature of the humidity regulating element. Specifically, when the refrigerant saturation temperature is lower than the regeneration temperature of the humidity conditioning element, the control module 502 controls the opening of the second throttling element to decrease. At this time, the liquid refrigerant in the second heat exchanger increases, while the two-phase refrigerant decreases, causing the condenser's condensing capacity to decrease. This leads to an increase in condensing pressure and refrigerant saturation temperature, thereby reducing the temperature difference between the absorbent material of the humidity conditioning element and the target regeneration temperature, effectively improving the humidity conditioning capacity of the humidity conditioning element. When the refrigerant saturation temperature is higher than the regeneration temperature of the humidity conditioning element, the control module 502 controls the opening of the second throttling element to increase. At this time, the liquid refrigerant in the second heat exchanger decreases, while the two-phase refrigerant increases, increasing the condenser's condensing capacity. This leads to a decrease in condensing pressure and refrigerant saturation temperature, thereby reducing the temperature difference between the absorbent material of the humidity conditioning element and the target regeneration temperature, effectively improving the humidity conditioning capacity of the humidity conditioning element. When the refrigerant saturation temperature is within the regeneration temperature range of the humidity conditioning element, the current opening of the second throttling element is maintained.

[0073] In one embodiment, the control module 502 is specifically used to: dehumidify via the humidifier when operating in cooling mode; and humidify via the humidifier when operating in heating mode. That is, since the humidifier has the ability to adsorb water vapor from the air, the control module 502 is specifically used to: when operating in cooling mode, heat the humidifier with air heated by the condenser of the refrigerant circuit; after being heated, the adsorbed water vapor in the humidifier is released and discharged outdoors, thereby dehumidifying the indoor air; and when operating in heating mode, heat the humidifier with air heated by the condenser of the refrigerant circuit; after being heated, the adsorbed water vapor in the humidifier is released and discharged indoors, thereby humidifying the indoor air.

[0074] In one embodiment, the humidifier is a ring-shaped adsorbent made of a renewable adsorbent material.

[0075] According to an embodiment of the present invention, the humidity control device of the humidity control equipment obtains the refrigerant saturation temperature through an acquisition module, and controls the first throttling element and the second throttling element according to the refrigerant saturation temperature through a control module to adjust the humidity control capability of the humidity control element. In this way, the refrigerant temperature of the condenser can be effectively controlled, the humidity control capability of the humidity control element can be improved, and the increase in compressor power consumption can be suppressed.
