Description

Technical Field

[0001] The present invention relates to the technical field of refrigeration systems, and particularly to a humidity control component, a refrigeration system and a humidity control method thereof. Background Art

[0002] Refrigeration systems are used in cold storages to refrigerate the cold storages and keep the cold storages at preset temperatures and humidities, where the preset temperatures and humidities are determined based on the types of items stored in the cold storages to facilitate the storage of items in the cold storages. With the increasing demand for cold storages in China, the requirements for the temperature and humidity of cold storages have also become higher. For example, the temperature and humidity of a pharmaceutical warehouse need to be maintained within a moderate range, while a fruit and vegetable warehouse needs to maintain a high humidity.

[0003] In existing refrigeration systems, the temperature and humidity in the cold storage are controlled in the following way: the humidity at the current temperature is detected, and the humidity is adjusted by changing the temperature in the cold storage. Specifically, when the temperature in the cold storage increases, the humidity decreases, and when the temperature in the cold storage decreases, the humidity increases. This kind of humidity control method is simple to operate. However, since the change rate of humidity is different at different temperatures, there is a situation where the humidity exceeds the preset range at some temperatures, making this method inapplicable to the humidity control at each temperature, and the temperature and humidity set values of different cold storages need to be repeatedly debugged, which is cumbersome to operate. On the other hand, this kind of humidity control method has a delay. Specifically, during the humidification or dehumidification process, when the humidity in the cold storage reaches the preset humidity, there is still some surplus to continue humidifying or dehumidifying the cold storage, resulting in the humidity exceeding the set range under some working conditions and unable to achieve the effect of precise humidity control. Therefore, there is an urgent need to provide a solution for precisely controlling the humidity of cold storages. Summary of the Invention

[0004] One of the objects of the present invention is to provide a humidity control component, which solves the technical problem in the prior art that controlling humidity by controlling temperature causes the humidity to exceed the preset range at some temperatures and cannot achieve precise humidity control. Many technical effects that can be produced by the preferred technical solution of the present invention are described in detail below.

[0005] To achieve the above object, the present invention provides the following technical solutions:

Among them, the weight detection component is arranged in the space to be controlled and is used to determine the weight of water vapor in the space to be controlled, and the humidity adjustment component is arranged in the space to be controlled. The humidity adjustment component is used to adjust the humidity of the space to be controlled and make the weight of water vapor in the space to be controlled within the first preset water vapor weight range.

Among them, the temperature detector is arranged in the space to be controlled and is used to detect the temperature in the space to be controlled, and the humidity detector is arranged in the space to be controlled and is used to detect the humidity in the space to be controlled. Moreover, the temperature detector and the humidity detector are used to determine a first preset water vapor weight range and the real-time water vapor weight in the space to be controlled. The first preset water vapor weight satisfies: Wd < W01 < Wg, where W01 is the first preset water vapor weight, Wd is the water vapor weight in the space to be controlled at the highest set temperature and the lowest set humidity, and Wg is the water vapor weight in the space to be controlled at the lowest set temperature and the highest set humidity.

[0011] The humidity control component provided by the present invention at least has the following beneficial technical effects:

[0012] The humidity control component of the present invention includes a weight detection component and a humidity adjustment component. Among them, the weight detection component is arranged in the space to be controlled and is used to determine the water vapor weight in the space to be controlled. The humidity adjustment component is arranged in the space to be controlled.

That is, for the control component of the present invention, the humidity adjustment component adjusts the humidity of the space to be controlled based on the water vapor weight in the space to be controlled. Since the change rate of the water vapor weight in the space to be controlled is not affected by temperature, the humidity in the space to be controlled can be accurately controlled by controlling the water vapor weight in the space to be controlled, so that the humidity of the space to be controlled is always within the preset value and will not exceed the set range.

[0013] That is, the humidity control component of the present invention solves the technical problem in the prior art that controlling humidity by controlling temperature results in the humidity exceeding the preset range at some temperatures and thus fails to achieve precise humidity control.

[0014] The second object of the present invention is to propose a refrigeration system.

[0017] The refrigeration system provided by the present invention has at least the following beneficial technical effects:

[0018] Since the refrigeration system of the present invention includes the humidity control component of any one of the technical solutions of the present invention, through the action of the humidity control component, the humidity of the space to be controlled can always be within the preset value and will not exceed the set range, thus playing the role of precise humidity control.

[0019] The third object of the present invention is to propose a method for controlling the humidity of a refrigeration system.

[0020] The method for controlling the humidity of the refrigeration system described in any one of the technical solutions of the present invention includes the following steps:

[0021] Obtain the real-time water vapor weight of the indoor space;

[0022] Compare the obtained real-time water vapor weight with the second preset water vapor weight;

[0024] The first preset water vapor weight satisfies: Wd < W01 < Wg, and the second preset water vapor weight satisfies Wd ≤ W02 ≤ Wg, where W01 is the first preset water vapor weight, W02 is the second preset water vapor weight, Wd is the water vapor weight in the room at the highest set temperature and the lowest set humidity, and Wg is the water vapor weight in the room at the lowest set temperature and the highest set humidity.

[0025] According to a preferred embodiment, obtaining the real-time water vapor weight of the indoor space includes the following steps:

[0026] Obtain the volume, temperature, and wet-bulb temperature of the indoor space;

[0027] Determine the absolute humidity of the indoor space based on the wet-bulb temperature of the indoor space;

[0029] According to a preferred embodiment, the first preset water vapor weight satisfies: Wd1 ≤ W01 ≤ Wg1, where Wd1 is the water vapor weight of the indoor space at the lowest set temperature and the lowest set humidity, and Wg1 is the water vapor weight of the indoor space at the highest set temperature and the highest set humidity.

[0030] According to a preferred embodiment, when Ws < Wd, control the humidity adjustment component to operate in the humidification mode, and the humidification amount is Wg1 - Ws;

[0031] When Ws > Wg, control the humidity adjustment component to operate in the dehumidification mode, and the dehumidification amount is greater than Ws - Wg1;

[0032] When Wd ≤ Ws ≤ Wg, control the refrigeration component to start the refrigeration mode, and record Ws1 = Ws, Wz1 = Wz, and Wx1 = Wx;

[0033] Where Ws is the real-time water vapor weight of the indoor space, Wg1 is the water vapor weight of the indoor space at the highest set temperature and the highest set humidity, Ws1, Wz1, and Wx1 are the water vapor weight of the indoor space, the weight of the evaporator, and the weight of the water tank when the real-time water vapor weight is within the second preset water vapor weight range, respectively, and Wz and Wx are the real-time weight of the evaporator and the real-time weight of the water tank, respectively.

[0037] During the refrigeration process, δWs, δWx, and δWz are the weight change of water vapor in the indoor space, the weight change of the evaporator, and the weight change of the water tank respectively, and δWs = Ws1 - Ws, δWx = Wx1 - Wx, δWz = Wz1 - Wz.

[0038] The humidity control method of the refrigeration system provided by the present invention has at least the following beneficial technical effects:

[0039] The humidity control method of the refrigeration system of the present invention includes obtaining the real-time water vapor weight of the indoor space, comparing the obtained real-time water vapor weight with the second preset water vapor weight, and based on the comparison result of the real-time water vapor weight and the second preset water vapor weight, controlling the working states of the humidity adjustment component and the refrigeration component, and making the real-time water vapor weight within the range of the first preset water vapor weight. This can keep the humidity of the space to be controlled within the preset value and not exceed the set range, thus playing a role in accurately controlling the humidity. Description of the Drawings

Detailed Embodiments

[0045] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope protected by the present invention.

[0046] The following will combine the description in the specification Figures 1 to 3 and Embodiments 1 to 3 to describe in detail the humidity control component, refrigeration system and humidity control method of the present invention.

[0047] Embodiment 1

[0048] This embodiment will describe in detail the humidity control component of the present invention.

[0049] The humidity control component of this embodiment includes a weight detection component and a humidity adjustment component, as Figure 1 shown. Preferably, the weight detection component is arranged in the space to be controlled and is used to determine the weight of water vapor in the space to be controlled, and the humidity adjustment component is arranged in the space to be controlled. The humidity adjustment component is used to adjust the humidity of the space to be controlled and make the weight of water vapor in the space to be controlled within a first preset water vapor weight range.

[0050] The humidity control component of the present invention includes a weight detection component and a humidity adjustment component. Among them, the weight detection component is arranged in the space to be controlled and is used to determine the weight of water vapor in the space to be controlled, and the humidity adjustment component is arranged in the space to be controlled. The humidity adjustment component is used to adjust the humidity of the space to be controlled and make the weight of water vapor in the space to be controlled within a first preset water vapor weight range. That is, for the control component of the present invention, the humidity adjustment component adjusts the humidity of the space to be controlled based on the weight of water vapor in the space to be controlled. Since the change rate of the weight of water vapor in the space to be controlled is not affected by temperature, the humidity of the space to be controlled can be accurately controlled by controlling the weight of water vapor in the space to be controlled, so that the humidity of the space to be controlled is always within the preset value and will not exceed the set range. That is, the humidity control component of the present invention solves the problem in the prior art that controlling humidity by controlling temperature causes the humidity to exceed the preset range at some temperatures and cannot achieve precise humidity control.

[0051] According to a preferred embodiment, the humidity control component further includes a temperature detector 101 and a humidity detector 102, as Figure 1As shown. Preferably, the temperature detector 101 is disposed in the space to be controlled and is used to detect the temperature in the space to be controlled, and the humidity detector 102 is disposed in the space to be controlled and is used to detect the humidity in the space to be controlled. The temperature detector 101 and the humidity detector 102 are used to determine the first preset water vapor weight range and the real-time water vapor weight in the space to be controlled. The first preset water vapor weight satisfies: Wd < W01 < Wg, where W01 is the first preset water vapor weight, Wd is the water vapor weight in the space to be controlled at the highest set temperature and the lowest set humidity, and Wg is the water vapor weight in the space to be controlled at the lowest set temperature and the highest set humidity. More preferably, the temperature detector 101 and the humidity detector 102 can respectively measure the temperature and humidity in the space to be controlled (the humidity measured by the humidity detector 102 is the wet-bulb temperature). Then, based on the volume of the space to be controlled, the formula W = V * S * 1.293 * 273.15 / (273.15 + T) is used to calculate the real-time water vapor weight in the indoor space, as well as Wd and Wg, where W is the water vapor weight in the indoor space, V is the indoor volume, S is the indoor absolute humidity (the absolute humidity can be obtained by referring to the relationship table between absolute humidity and wet-bulb temperature), and T is the indoor temperature.

[0052] The humidity control component of the preferred technical solution of this embodiment further includes a temperature detector 101 and a humidity detector 102. The temperature detector 101 and the humidity detector 102 can be used to determine the first preset water vapor weight range and the real-time water vapor weight in the space to be controlled, so as to provide a basis for starting and stopping the humidity adjustment component. Further, since the first preset water vapor weight satisfies: Wd < W01 < Wg, after the water vapor weight in the space to be controlled reaches the first preset water vapor weight range, even if the remaining amount of the humidity adjustment component is used to humidify or dehumidify the space to be controlled, the humidity of the space to be controlled will not exceed the preset value, thereby further playing a role in precise humidity control. It can be seen that the humidity control component of the preferred technical solution of this embodiment solves the technical problem that the existing cold storage humidity control method has a delay, resulting in the humidity exceeding the set range in some working conditions and unable to achieve precise humidity control.

[0053] According to a preferred embodiment, the weight detection component includes a first weight detector 103 and a second weight detector 104. Among them, the first weight detector 103 is used to detect the weight of the evaporator 20 in the refrigeration system, and the second weight detector 104 is used to detect the weight of the water tank 30 in the refrigeration system, as Figure 1As shown. During the refrigeration process of the refrigeration system, part of the water vapor in the air condenses on the evaporator 20, and part becomes condensed water and drains into the water tank 30, reducing the air humidity. The humidity control component of the preferred technical solution of this embodiment can obtain the weight of the evaporator 20 and the weight of the water tank 30 through the first weight detector 103 and the second weight detector 104. Based on the weight change of the evaporator 20 and the weight change of the water tank 30, the weight change of the water vapor in the space to be controlled can be determined, thereby providing a basis for starting and stopping the humidity adjustment component.

[0054] According to a preferred embodiment, the humidity adjustment component includes a humidification component 105 and a dehumidification component 106, as Figure 1 shown. Preferably, the humidification component 105 is used to increase the humidity in the space to be controlled, and the dehumidification component 106 is used to reduce the humidity in the space to be controlled, as Figure 1 shown. Preferably, the structure of the dehumidification component 106 can be the same as that of the prior art. For example, the dehumidification component 106 is a dehumidifier. The humidity control component of the preferred technical solution of this embodiment can adjust the humidity in the space to be controlled through the humidification component 105 and the dehumidification component 106, so that the humidity in the space to be controlled is maintained within a preset range, which is beneficial to the storage of food.

[0055] According to a preferred embodiment, the humidification component 105 includes a first heater 1051 and a second heater 1052, as Figure 1 shown. Preferably, the first heater 1051 is arranged at the evaporator 20 of the refrigeration system. The first heater 1051 is used to defrost the evaporator 20 and make the water vapor generated during the defrosting process enter the space to be controlled; the second heater 1052 is arranged at the water tank 30 of the refrigeration system. The second heater 1052 is used to heat the water tank 30 and make the water vapor generated during the heating process enter the space to be controlled. The humidity control component of the preferred technical solution of this embodiment heats the evaporator 20 through the first heater 1051 and heats the water tank 30 through the second heater 1052, so that the steam generated during the heating process can be discharged into the space to be controlled to increase the humidity in the space to be controlled. At the same time, it can also defrost the evaporator 20 and improve the heat exchange efficiency of the evaporator 20. The humidity control component of the preferred technical solution of this embodiment can heat the water reduced in the space to be controlled again and discharge it into the space to be controlled during the humidification process, which can make full use of the original water source and play a role in saving water.

[0056] Embodiment 2

[0057] This embodiment describes the refrigeration system of the present invention in detail.

[0058] The refrigeration system of this embodiment includes a refrigeration component and a humidity control component. Preferably, the humidity control component is the humidity control component of any one of the technical solutions in Embodiment 1, and the refrigeration component is used to refrigerate the interior, and the humidity control component is used to control the indoor humidity. Preferably, the refrigeration system of this embodiment is used to refrigerate a cold storage.

[0059] Since the refrigeration system of this embodiment includes the humidity control component of any one of the technical solutions in Embodiment 1, through the action of the humidity control component, the humidity of the space to be controlled can always be within the preset value and will not exceed the set range, thus playing the role of precise humidity control.

[0060] According to a preferred embodiment, the refrigeration component includes an evaporator 20, a water tank 30 and an outdoor unit 40. Among them, the outlet of the outdoor unit 40, the evaporator 20 and the inlet of the outdoor unit 40 are connected in sequence to form a refrigerant circuit; the inlet of the water tank 30 is communicated with the evaporator 20, and the outlet of the water tank 30 is communicated with the outside, as Figure 2 shown. The refrigeration system of the preferred technical solution of this embodiment has the same refrigeration process as the prior art and will not be elaborated here. The refrigeration system of the preferred technical solution of this embodiment is also provided with a water tank 30. The water tank 30 can not only collect the condensed water generated by the evaporator 20, but also, since there is water stored in the water tank 30, the water tank 30 can also play the role of isolating the cold storage from the outside air circulation, acting as a return bend of the cold storage and avoiding the loss of cold in the cold storage.

[0061] Embodiment 3

[0062] This embodiment elaborates in detail on the humidity control method of the refrigeration system of the present invention.

[0063] Figure 3 The flowchart of the humidity control method of the refrigeration system of this embodiment is shown. As Figure 3 shown, the humidity control method of the refrigeration system of any one of the technical solutions in Embodiment 2 includes the following steps:

[0064] Step 1: Obtain the real-time water vapor weight of the indoor space.

[0065] Step 2: Compare the obtained real-time water vapor weight with the second preset water vapor weight.

[0066] Step 3: Based on the comparison result between the real-time water vapor weight and the second preset water vapor weight, control the working states of the humidity adjustment component and the refrigeration component, and make the real-time water vapor weight within the range of the first preset water vapor weight. Preferably, the first preset water vapor weight satisfies: Wd < W01 < Wg, and the second preset water vapor weight satisfies Wd ≤ W02 ≤ Wg, where W01 is the first preset water vapor weight, W02 is the second preset water vapor weight, Wd is the water vapor weight in the room at the highest set temperature and the lowest set humidity, and Wg is the water vapor weight in the room at the lowest set temperature and the highest set humidity.

[0067] The humidity control method of the refrigeration system in this embodiment includes the steps of obtaining the real-time water vapor weight of the indoor space, comparing the obtained real-time water vapor weight with the second preset water vapor weight, controlling the working states of the humidity adjustment component and the refrigeration component based on the comparison result between the real-time water vapor weight and the second preset water vapor weight, and making the real-time water vapor weight within the range of the first preset water vapor weight, which can keep the humidity of the space to be controlled within the preset value without exceeding the set range, thus playing a role in accurately controlling the humidity.

[0068] According to a preferred embodiment, obtaining the real-time water vapor weight of the indoor space includes the following steps: obtaining the volume, temperature and wet bulb temperature of the room; determining the absolute humidity of the room based on the wet bulb temperature of the room (the humidity detected by the humidity detector 102 is the wet bulb temperature, and the absolute humidity can be obtained by referring to the relationship table between absolute humidity and wet bulb temperature); using the formula Ws = V * S * 1.293 * 273.15 / (273.15 + T) to calculate the real-time water vapor weight of the indoor space, where Ws is the real-time water vapor weight of the indoor space, V is the indoor volume, S is the indoor absolute humidity, and T is the indoor temperature. The humidity control method of the preferred technical solution of the refrigeration system in this embodiment can provide a basis for starting and stopping the humidity adjustment component and the refrigeration component by obtaining the real-time water vapor weight of the indoor space.

[0069] According to a preferred embodiment, the first preset water vapor weight satisfies: Wd1 ≤ W01 ≤ Wg1, where Wd1 is the water vapor weight in the room at the lowest set temperature and the lowest set humidity, and Wg1 is the water vapor weight in the room at the highest set temperature and the highest set humidity. In the humidity control method of the preferred technical solution of the refrigeration system in this embodiment, the first preset water vapor weight satisfies: Wd1 ≤ W01 ≤ Wg1, so that when the water vapor weight in the room reaches the range of the first preset water vapor weight and continues to humidify or dehumidify the room through the margin of the humidity adjustment component, the indoor humidity is closer to the preset value, thereby further improving the accuracy of humidity control.

[0070] According to a preferred embodiment, based on the preset temperature range and humidity range indoors, Wd, Wg, Wd1, and Wg1 can be calculated using the formula W = V * S * 1.293 * 273.15 / (273.15 + T). Specifically, Wd = V * Sd * 1.293 * 273.15 / (273.15 + T1), Wg = V * Sg * 1.293 * 273.15 / (273.15 + T2), Wd1 = V * Sd * 1.293 * 273.15 / (273.15 + T2), Wg1 = V * Sg * 1.293 * 273.15 / (273.15 + T1), where T1 is the maximum value of the indoor set temperature, T2 is the minimum value of the indoor set temperature, Sd is the minimum value of the indoor set humidity, and Sg is the maximum value of the indoor set humidity.

[0071] According to a preferred embodiment, when Ws < Wd, control the humidity adjustment component to operate in the humidification mode, and the humidification amount is Wg1 - Ws; when Ws > Wg, control the humidity adjustment component to operate in the dehumidification mode, and the dehumidification amount is greater than Ws - Wg1; when Wd ≤ Ws ≤ Wg, control the refrigeration component to start the refrigeration mode, and record Ws1 = Ws, Wz1 = Wz, Wx1 = Wx; where Ws is the real-time water vapor weight in the indoor space, Wg1 is the water vapor weight in the indoor at the highest set temperature and the highest set humidity, Ws1, Wz1, and Wx1 are respectively the water vapor weight in the indoor space, the weight of the evaporator 20, and the weight of the water tank 30 when the real-time water vapor weight is within the second preset water vapor weight range, and Wz and Wx are respectively the real-time weight of the evaporator 20 and the real-time weight of the water tank 30. In the preferred technical solution of the humidity control method of the refrigeration system in this embodiment, when humidification is required, the humidification amount is Wg1 - Ws, and when dehumidification is required, the dehumidification amount is greater than Ws - Wg1. This not only ensures that even if the margin of the humidity adjustment component is used to continue humidifying or dehumidifying the space to be controlled, the humidity of the space to be controlled will not exceed the preset value, playing a role in precise humidity control; but also makes the humidity in the room closer to the preset value after the margin of the humidity adjustment component is used to continue humidifying or dehumidifying the indoor space, thereby further improving the precision of humidity control.

[0072] According to a preferred embodiment, when the refrigeration component starts the refrigeration mode, the following steps are further included: monitoring the weight change of water vapor in the indoor space, the weight change of the evaporator 20, and the weight change of the water tank 30; when δWs + δWx + δWz = Wg1 - Wd, controlling the humidity adjustment component to operate in the humidification mode and making Ws = Ws1, Wx = Wx1, or making the indoor real-time temperature reach the highest set temperature, where δWs, δWx, and δWz are respectively the weight change amount of water vapor in the indoor space, the weight change amount of the evaporator 20, and the weight change amount of the water tank 30 during the refrigeration process, and δWs = Ws1 - Ws, δWx = Wx1 - Wx, δWz = Wz1 - Wz. In the preferred technical solution of the humidity control method of the refrigeration system in this embodiment, during the refrigeration process of the refrigeration component, part of the water vapor in the air condenses on the evaporator 20, and part becomes condensed water and drains into the water tank 30, reducing the air humidity. When it is detected that δWs + δWx + δWz = Wg1 - Wd, controlling the humidity adjustment component to operate in the humidification mode can ensure that within the set temperature range, the indoor humidity will not exceed the preset range, further improving the accuracy of humidity control.
