Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning and refrigeration, and in particular to a refrigeration system and a control method. Background Art

[0002] Air conditioning systems are commonly used household appliances. Air conditioning generally covers the living room and bedroom, but not the kitchen and bathroom. However, the kitchen and bathroom also have the need for air conditioning.

[0003] The air conditioners in the kitchen and bathroom spaces are generally fixed-frequency air conditioners, and the biggest difference between the air conditioners in the kitchen and bathroom spaces and those in the living room and bedroom is that the air conditioners in the kitchen and bathroom spaces only cool people rather than the entire house, so the air conditioners in the kitchen and bathroom spaces generally blow directly towards people.

[0004] In the prior art, the cold storage water tank of the fixed-frequency air conditioner includes three stages during use. During the first predetermined time period, the cold storage water tank is in an overcooling stage, generally -5°C; during the second predetermined time period, the cold storage water tank is at an ice-water mixed temperature, generally 0°C; during the third predetermined time period, the amount of ice in the cold storage water tank decreases and the temperature rises rapidly, reaching a maximum of more than 10°C; because the temperature difference between the three stages of the cold storage water tank in the fixed-frequency air conditioner is large, the cold air blown out by the fixed-frequency air conditioner also has a large temperature difference and blows directly to the user, which is easy to cause the user to feel bad. Summary of the invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect of poor user experience caused by large temperature difference in the prior art, thereby providing a refrigeration system.

[0026] Exchange heat between the refrigeration device and the cold storage agent to enable the cold storage agent to store cold;

[0046] Embodiment 1

[0047] As Figure 1 shown, this embodiment provides a refrigeration system, including a cold storage tank 1, a refrigeration device 2, a cold extraction device 3, a vibration structure 4, and a temperature detection unit 5. The cold storage tank 1 stores a cold storage agent inside. The refrigeration device 2 is connected to the cold storage tank 1, and the refrigeration device 2 is adapted to exchange heat with the cold storage agent. In this embodiment, the refrigeration device 2 reduces the temperature of the cold storage agent. The cold extraction device 3 is inserted into the cold storage tank 1 and is adapted to exchange heat with the cold storage tank 1. The cold extraction device 3 obtains the cold in the cold storage tank 1; and a heat exchange medium is adapted to flow inside the cold extraction device 3; the cold extraction device 3 includes an adjustment structure 31, and the adjustment structure 31 is adapted to adjust the flow rate of the heat exchange medium. Among them, the vibration structure 4 is drivingly connected to the cold storage tank 1 and / or the part of the cold extraction device 3 located inside the cold storage tank 1. Among them, the temperature detection unit 5 is arranged corresponding to the cold supply surface of the cold extraction device 3. The temperature detection unit 5 is electrically connected to the adjustment structure 31 and the vibration structure 4. By monitoring the temperature of the cold supply surface of the cold extraction device 3 through the temperature detection unit 5 and feeding it back to the adjustment structure 31 and the vibration structure 4, then controlling the adjustment structure 31 and the vibration structure 4 to regulate the user temperature.

[0048] In this solution, the temperature of the coolant in the cold storage tank 1 is reduced by the refrigeration device 2, and the cold energy in the cold storage tank 1 is extracted by the cold extraction device 3. According to the temperature detected by the temperature detection unit 5 of the cold extraction device 3 at the cold supply surface, by controlling the vibration structure 4 and the adjustment structure 31, the temperature of the cold supply surface of the cold extraction device 3 is adjusted. The temperature in the cold demand tank gradually increases over time. By controlling the vibration structure 4 and the adjustment structure 31, the temperature change of the cold supply surface of the cold extraction device 3 becomes gentler, preventing discomfort caused to users due to excessive temperature difference at the cold supply surface of the cold extraction device 3 and increasing user comfort.

[0049] It should be noted that this refrigeration system is applied to the ceiling lamp device in the kitchen and bathroom.

[0050] It should be noted that the vibration structure 4 mainly functions to vibrate the coolant. If the vibration structure 4 is not provided, the temperature distribution of the coolant will be uneven, affecting the heat exchange effect between the coolant and the cold extraction device 3. If the vibration structure 4 is not provided, the temperature of the cold supply surface of the cold extraction device 3 will fluctuate greatly, resulting in a poor user experience.

[0051] It should be noted that in this embodiment, the vibration structure 4 is connected to the part of the cold extraction device 3 located inside the cold storage tank 1 in a transmission manner. As an alternative implementation, the vibration structure 4 can also be connected to the cold storage tank 1, or vibration structures 4 can be provided on both the cold extraction device 3 and the vibration structure 4. In this embodiment, the vibration structure 4 is a vibration motor. As an alternative implementation, the vibration structure 4 can also be an ultrasonic structure, vibrating in the way of ultrasonic vibration.

[0052] It should be noted that the cold extraction device 3 also includes a cold extraction pipeline, and the heat exchange medium is circulated inside the cold extraction pipeline. The cold extraction pipeline is inserted into the cold storage tank 1. In this solution, copper pipes are selected for the cold extraction pipeline. As an alternative implementation, other materials with good thermal conductivity can also be selected for the cold extraction pipeline; the heat exchange medium and the coolant are in indirect contact through the copper pipe, thereby realizing heat exchange.

[0053] It should be noted that the adjustment structure 31 is a water pump in this solution, and the flow rate of the heat exchange medium is adjusted by adjusting the power of the water pump. Specifically, when the power of the water pump is increased, the flow rate of the heat exchange medium increases; when the power of the water pump is decreased, the flow rate of the heat exchange medium decreases. It should be noted that the water pump is also simply referred to as the pump hereinafter.

[0054] It should be noted that the coolant is a semi-transparent (or opaque), viscous colloidal mixture composed of organic or (and) inorganic compounds, which can absorb and store a large amount of cold energy at low temperatures and release a large amount of cold energy at higher temperatures, maintaining a low-temperature environment for itself and the small surrounding area for a long time.

[0055] It should be noted that in order to increase the contact area between the cold extraction device 3, the refrigeration device 2 and the cold storage agent, the pipelines in the sole cold storage tank 1 are all bent and distributed.

[0056] Furthermore, the refrigeration system further includes a blowing component 6. The blowing component 6 is arranged on one side of the cold extraction device 3. The blowing component 6 is adapted to blow air towards the cold extraction device 3. The cold extraction device 3 brings cold to the user through the air flow passing through its surface. If the blowing component 6 is not provided, the cold extraction device 3 can also transfer cold to the user through the way of natural radiation. However, the efficiency of the natural radiation method is low. Therefore, by setting the blowing component 6, the cold extraction device 3 can increase the efficiency of cold transfer.

[0057] It should be noted that the blowing component 6 also includes a blowing fan. By blowing air towards the cold extraction device 3 through the blowing fan, the air passing through the surface of the cold extraction device 3 is increased. The cold extraction device 3 transfers the cold in it to the user by exchanging heat with the air flowing through it.

[0058] Furthermore, the temperature detection unit 5 includes an air outlet temperature sensor 51 and a return air temperature sensor 52. The air outlet temperature sensor 51 is arranged on the cold extraction surface of the cold extraction device 3. The air outlet temperature sensor 51 is used to detect the temperature of the air flow passing through the cold extraction device 3. The temperature of the air flow passing through the cold extraction device 3 is basically equal to the temperature reaching the user. By monitoring the temperature of the air outlet temperature sensor 51, the frequency of the vibration structure 4, the flow rate of the heat exchange medium and the rotation speed of the blowing fan are adjusted, so as to realize the adjustment of the temperature reaching the user.

[0059] It should be noted that in this embodiment, referring to the control logic of a variable frequency air conditioner, the temperature of the air conditioner is adjusted by controlling the frequency of the compressor. For example, in the first scheme, according to the absolute value △T of the difference between the return air temperature and the target temperature, when △T>T1, the frequency of the pump is increased / decreased by △f each time; when △T≤T1, the frequency of the pump maintains the previous frequency; in the second scheme, according to the absolute value △T of the difference between the return air temperature and the target frequency, when △T>T1, the frequency of the pump is increased / decreased by △f each time; when T2<△T≤T1, the increased value of the frequency of the pump each time is 1 / 2*△f; when T3<△T≤T2, the increased value of the frequency of the pump each time is 1 / 2*1 / 2*△f; and so on in a cycle until when Tn<△T≤Tn-1, the frequency of the pump remains unchanged. (This ratio of 1 / 2 is an example, and this ratio can be any number less than or equal to 1 and greater than or equal to 0. Further, this value can be a value that changes with n)

[0060] The duration of each change described above is 30s≥t>0s; the maximum value of the change in the frequency of the pump is 30Hz≥△T>0Hz;

[0061] Further, the refrigeration device 2 includes a refrigeration pipeline 21, a refrigeration component 22 and a heat dissipation component 23. The refrigeration pipeline 21 is suitable for extending into the cold storage box 1 and contacting the cold storage agent for heat exchange. A heat exchange medium is arranged in the refrigeration pipeline 21. It should be noted that in this embodiment, the heat exchange medium is water. The refrigeration pipeline 21 is made of copper, and the copper tube has a good thermal conductivity. The refrigeration component 22 is arranged on the refrigeration pipeline 21. The refrigeration component 22 is used to reduce the temperature of the heat exchange medium in the refrigeration pipeline 21. In this embodiment, the refrigeration component 22 includes a compressor and related equipment matched with the compressor. As an alternative embodiment, the refrigeration component 22 can also be a semiconductor component, and the heat exchange medium is cooled by semiconductor refrigeration. A heat dissipation fan 232 is arranged on one side of the heat exchange pipeline. The heat dissipation fan 232 blows toward the heat dissipation pipeline 231. The heat dissipation fan 232 contacts the heat dissipation pipeline 231 through the airflow and cools the heat dissipation pipeline 231. In order to facilitate the control of the heat dissipation pipeline 231, an expansion valve is also arranged on the heat exchange pipeline.

[0062] It should be noted that, in order to increase the heat exchange effect of the heat exchange pipeline, the heat exchange pipeline is bent along the direction of the airflow of the heat dissipation fan 232.

[0063] Example 2

[0064] A control method provided in this embodiment includes a refrigeration system in embodiment 1. In this embodiment, a control method includes the steps of: exchanging heat with the refrigerant through the refrigeration device 2, so that the refrigerant stores cold; then exchanging heat with the refrigerant in the cold storage box 1 through the heat exchange and cold extraction device 3, and blowing the cold on the heat exchange device to the user through the airflow to diffuse the cold to the outside; wherein the temperature in the cold storage box 1 changes with time including a first predetermined time period, a second predetermined time period and a third predetermined time period; in the first predetermined time period, the flow rate of the heat exchange medium is gradually increased by controlling the frequency of the regulating structure 31, and the vibration structure 4 is turned off while keeping other variables unchanged; in the second predetermined time period, the frequency of the regulating structure 31 is kept unchanged, the vibration structure 4 is started, and other variables are kept unchanged; in the third predetermined time period, the frequency of the regulating structure 31 is increased, the frequency of the vibration structure 4 is increased, and other variables are kept unchanged.

[0065] like Figure 2As shown, it should be noted that T0 is approximately the temperature of the ice-water mixture, that is, 0°C. During the cold storage process of the cold storage box 1, since there needs to be a degree of supercooling during the freezing process, the temperature of the cold storage box 1 is initially lower than T0; when the ice around the part of the cold-taking pipeline located in the cold storage box 1 melts, it becomes an ice-water mixture, that is, at time t1, it reaches the ice-water mixture temperature T0, and the time period 0-t1 is the stage of ice melting; in the time period t1-t2, since it is an ice-water mixture, the temperature is basically constant, or the temperature is in a slowly rising state; in the time period t2-t3, since there is little remaining ice, the temperature continues to rise.

[0066] It should be noted that, in this embodiment, the first predetermined time period is the time period from 0 to t1, the second predetermined time period is the time period from t1 to t2, and the third predetermined time period is the time period from t2 to t3.

[0067] It should be noted that, in this embodiment, if the water pump is not adjusted, Figure 2 As shown, in the first predetermined time period, the user will feel a lower temperature. Generally, the cold storage box 1 is provided with an overcooling capacity. In this embodiment, the overcooling capacity is -5°C. The user may experience -5°C cold air in the first predetermined time period. In the second predetermined time period, the cold storage box 1 is in an ice-water mixture state. The user experiences cold air of about 0°C in the second predetermined time period. In the third predetermined time period, the amount of ice in the cold storage box 1 decreases and the temperature rises. The user experiences 10°C cold air in the third predetermined time period. If the water pump is not adjusted, the temperature difference of the cold air blown out by the air-conditioning system will be large, resulting in a poor user experience. It should be noted that in Figure 2 In the figure, the horizontal axis is time, the vertical axis is the user's perceived temperature, the K line is the temperature change felt by the user when the water pump is not adjusted, and the L line is the temperature change after the water pump is adjusted. It can be seen from the figure that in the 0-t1 period, the K line has a larger inclination angle than the L line, indicating that the temperature difference is also larger. In the t2-t3 period, the K line has a larger inclination angle than the L line, indicating that the temperature difference is also larger. Therefore, through Figure 2 It can also be clearly seen that this solution reduces the discomfort caused to users and increases user comfort by reducing the temperature difference.

[0068] It should be noted that the intervention of the vibration structure 4 will affect the outlet air temperature. The vibration structure 4 will increase the heat transfer efficiency in the cold storage box 1. The intervention of the vibration structure 4 can reduce the outlet air temperature. If the vibration structure 4 is not set, the temperature of the surface of the cooling pipe will be the position with the highest temperature in the cold storage box 1. By setting the vibration structure 4, the temperature of the surface of the cooling pipe is reduced in disguise.

[0069] It should be noted that in this embodiment, if the air output of the blowing component 6 remains unchanged, in order to adjust the outlet air temperature, the variables in this embodiment are the frequency of the adjusting structure 31 and the intervention of the vibration structure 4. Specifically, within the first predetermined time period, the flow rate of the heat exchange medium is gradually increased by controlling the frequency of the adjusting structure 31, and the vibration structure 4 is turned off while keeping other variables unchanged; within the second predetermined time period, the frequency of the adjusting structure 31 is kept unchanged, and the vibration structure 4 is started while keeping other variables unchanged; within the third predetermined time period, the frequency of the adjusting structure 31 is increased, and the frequency of the vibration structure 4 is increased while keeping other variables unchanged.

[0070] It should be noted that within the first predetermined time period, in order to gradually increase the flow rate of the heat exchange medium controlled by the adjusting structure 31, the frequency of the adjusting structure 31 is slowly increased. In the second predetermined time period, the frequency of the adjusting structure 31 is kept unchanged or increased at an extremely slow frequency, or the vibration structure 4 intervenes. Within the third predetermined time period, the frequency of the adjusting structure 31 is further increased and the vibration structure 4 is made to intervene. It should be noted that the above adjusting structure 31 and vibration structure 4 cause the temperature in the cold storage box 1 to show an upward trend as the frequency of the adjusting structure 31 increases. However, there are some fluctuations during this period, but the overall trend is upward.

[0071] Furthermore, when the adjusting structure 31 and the vibration structure 4 are kept unchanged, adjusting the air output of the blowing component 6 can adjust the outlet air temperature monitored by the outlet air temperature sensor 51; increasing the air volume blown by the blowing component 6 causes the temperature of the outlet air monitored by the outlet air temperature sensor 51 to decrease; reducing the air output of the blowing component 6 causes the temperature of the outlet air detected by the outlet air temperature sensor 51 to increase.

[0072] It should be noted that during use, there is also a concept that the wind follows the person. The blowing component 6 further includes a sensor and a wind deflector. The sensor is used to detect the distance between the person and the blowing component 6, as well as the positional relationship between the person and the blowing component 6. Then, by adjusting the angle of the wind deflector, it is ensured that the wind blown out by the blowing component 6 can follow the person's movement. And to ensure the user experience, the rotation speed of the blowing component 6 is inversely proportional to the distance from the person. The closer the person is to the blowing component 6, the slower the rotation speed of the blowing component 6; the farther the person is from the blowing component 6, the faster the rotation speed of the blowing component 6. It should be noted that in this embodiment, when the person stands directly below the blowing component 6, the wind deflector forms a 90° angle with the horizontal plane. When the person stands off the direct center below, the angle between the wind deflector and the horizontal plane is 60°. This will cause the wind deflector at different angles to increase the wind resistance. Therefore, the rotation speed of the fan is directly proportional to the air volume, and the angle of the wind deflector is directly proportional to the air volume. Assuming that the air volume is Y, the fan rotation speed is X1, and the wind deflector angle is X2, then a*X1 + b*X2 = Y, or a1*X1^2 + a2*X1 + b1*X2^2 + b2*X2 = Y, where a / a1 / a2 / b / b1 / b2 are constants, and their magnitudes are determined according to actual tests; thereby determining the air volume Y.

[0073] Furthermore, the control method further includes: sensing the position of the person, determining the angle of the wind deflector and the rotation speed of the fan according to the position of the person, and adjusting the vibration frequency of the vibration structure 4 and the flow rate of the heat exchange medium controlled by the adjustment structure 31 according to the detection result of the air outlet temperature sensor 51, ultimately ensuring that an air flow with appropriate blowing temperature, direction, and speed is blown out.

[0074] In this embodiment, the adjustment structure 31, the vibration structure 4, and the rotation speed of the blowing fan are adjusted synchronously. During the first predetermined time period, the flow rate of the heat exchange medium is gradually increased by controlling the frequency of the adjustment structure 31, and the wind speed of the blowing component 6 is also gradually increased, while the vibration structure 4 is turned off with other variables unchanged; during the second predetermined time period, the frequency of the adjustment structure 31 is kept unchanged, the fan of the blowing component 6 remains basically unchanged, the vibration structure 4 is started, and other variables are kept unchanged; during the third predetermined time period, the frequency of the adjustment structure 31 is increased, the frequency of the vibration structure 4 is increased, and the rotation speed of the fan of the blowing component 6 is increased, while other variables are kept unchanged.

[0075] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or alterations can be made based on the above description. It is not necessary and impossible to enumerate all implementation manners here. And the obvious changes or alterations derived therefrom still fall within the protection scope of the present invention.
