[0035] Example 1
[0036] Figure 1 This is a flowchart of a method for preventing condensation in a refrigeration device according to Embodiment 1 of the present invention. This embodiment is applicable to application scenarios where the operating parameters of the refrigeration device are adjusted by the temperature difference between the inside and outside of the fresh air device to achieve the function of preventing condensation at the fresh air inlet. The method can be executed by an anti-condensation control device, which can be implemented in hardware and / or software. The anti-condensation control device for the refrigeration device can be configured in an electronic device.
[0037] In embodiments of the present invention, the refrigeration equipment includes a fresh air unit and an air conditioning unit. The fresh air unit includes a fresh air duct, a fresh air fan assembly, and a fresh air preheating assembly. The air conditioning unit includes an indoor unit and an outdoor unit, wherein the indoor unit, the fresh air fan assembly, and the fresh air preheating assembly are all installed indoors.
[0038] like Figure 1 As shown, the anti-condensation control method for this refrigeration equipment specifically includes the following steps:
[0039] Step S1: Obtain indoor and outdoor environmental parameters.
[0040] The indoor environmental parameters include, but are not limited to: indoor ambient temperature, indoor ambient humidity, and indoor ambient pressure where the refrigeration equipment is located. The outdoor environmental parameters include, but are not limited to: outdoor ambient temperature, outdoor ambient humidity, and outdoor ambient pressure where the refrigeration equipment is located.
[0041] In some embodiments, indoor and outdoor ambient temperatures can be used as control parameters for the anti-condensation function. Specifically, a first temperature sensor can be installed on the surface of any device arranged indoors in the refrigeration equipment to collect indoor environmental parameters (i.e., indoor ambient temperature); a second temperature sensor can be installed at the inlet of the fresh air duct to collect outdoor environmental parameters (i.e., outdoor ambient temperature).
[0042] Step S2: Determine the start / stop conditions for the anti-condensation function of the fresh air unit based on outdoor environmental parameters.
[0043] Among them, the anti-condensation start-stop conditions can be the critical parameters that control the start or stop of the anti-condensation function.
[0044] In some embodiments, the anti-condensation start / stop conditions include start conditions and stop conditions, wherein the parameter value of the start condition is greater than the parameter value of the stop condition. Specifically, the start condition is a critical parameter adjustment for activating the anti-condensation function, and the stop condition is a critical parameter adjustment for deactivating the anti-condensation function.
[0045] It should be noted that the lower the outdoor ambient temperature, the greater the probability of condensation forming in the fresh air inlet. Therefore, the activation and deactivation conditions of the anti-condensation function can be set based on the outdoor ambient temperature.
[0046] Step S3: Determine the target control strategy for the refrigeration equipment based on indoor environmental parameters, outdoor environmental parameters, and anti-condensation start-up and shutdown conditions.
[0047] The target control strategy includes at least: fresh air operation mode and equipment control parameters, and the fresh air operation mode includes at least: anti-condensation mode and non-anti-condensation mode.
[0048] In embodiments of the present invention, the equipment control parameters are set corresponding to the fresh air operation mode. In anti-condensation mode, the equipment control parameters of the refrigeration equipment aim to reduce the difference between indoor and outdoor environmental parameters and avoid condensation at the fresh air inlet, while also taking into account environmental comfort. In non-anti-condensation mode, the equipment control parameters of the refrigeration equipment aim to increase indoor temperature and achieve indoor and outdoor air exchange, without considering the anti-condensation effect.
[0049] Step S4: Control the operation of the fresh air unit according to the fresh air operation mode, and control the operation of the air conditioning unit according to the equipment control parameters.
[0050] In some embodiments, in anti-condensation mode, the fresh air fan assembly and fresh air preheating assembly can be shut down, while reducing the air volume and air temperature of the air conditioning unit; in non-anti-condensation mode, the fresh air fan assembly and fresh air preheating assembly can be started, while increasing the air volume and air temperature of the air conditioning unit.
[0051] In other embodiments, in anti-condensation mode, the fresh air fan assembly can be controlled to shut down, and the fresh air preheating assembly can be controlled to operate at a lower heating power, while reducing the air volume and air temperature of the air conditioning unit; in non-anti-condensation mode, the fresh air fan assembly and fresh air preheating assembly can be controlled to start, while increasing the air volume and air temperature of the air conditioning unit.
[0052] Specifically, the refrigeration equipment is equipped with a fresh air unit and an air conditioning unit. Upon receiving a fresh air start command, it controls the fresh air unit to start and perform ventilation; upon receiving an air conditioning start command, it controls the air conditioning unit to start and perform cooling or heating.
[0053] During the simultaneous operation of the air conditioning unit and the fresh air unit, indoor and outdoor environmental parameters are monitored in real time to obtain the anti-condensation start / stop conditions corresponding to the current outdoor environmental parameters. If the current indoor and outdoor environmental parameters meet the current anti-condensation start conditions, the fresh air operation mode is set to anti-condensation mode, and the equipment control parameters are set to the equipment control parameters corresponding to the anti-condensation mode. The fresh air fan assembly and fresh air preheating assembly are controlled to shut down, while the air volume and outlet temperature of the air conditioning unit are reduced to reduce the difference between indoor and outdoor environmental parameters and avoid the risk of condensation at the fresh air inlet. If the current indoor and outdoor environmental parameters do not meet the current anti-condensation start conditions, the fresh air operation mode is set to non-anti-condensation mode, and the equipment control parameters are set to the equipment control parameters corresponding to the non-anti-condensation mode. The fresh air fan assembly and fresh air preheating assembly are controlled to start, while the air volume and outlet temperature of the air conditioning unit are increased to raise the indoor temperature and achieve indoor and outdoor air exchange, without considering the anti-condensation effect. By detecting differences in indoor and outdoor environmental parameters, the system adjusts the fresh air operation mode and equipment control parameters in real time, solving the problem that existing fresh air conditioners are prone to condensation during heating, which harms user interests and results in a poor user experience. It avoids the risk of condensation at the fresh air inlet, improves ventilation and temperature regulation, maintains indoor temperature and humidity comfort, and enhances the user experience.
[0054] In some embodiments, the device control parameters include: the frequency of the first outdoor unit and the speed of the first indoor unit in anti-condensation mode, and the frequency of the second outdoor unit and the speed of the second indoor unit in non-anti-condensation mode; the frequency of the first outdoor unit is less than the frequency of the second outdoor unit; and the speed of the first indoor unit is less than the speed of the second indoor unit.
[0055] Specifically, in anti-condensation mode, the air outlet temperature of the air conditioner can be lowered by reducing the operating frequency of the outdoor unit (i.e., the compressor) (e.g., setting a first outdoor unit frequency), and the air volume of the air conditioner can be lowered by reducing the speed of the indoor unit (e.g., setting a first indoor unit speed). This reduces the difference in indoor and outdoor environmental parameters and avoids the control objective of condensation at the fresh air inlet. In non-anti-condensation mode, the air outlet temperature of the air conditioner can be increased by increasing the operating frequency of the outdoor unit (i.e., the compressor) (e.g., setting a second outdoor unit frequency), and the air volume of the air conditioner can be increased by increasing the speed of the indoor unit (e.g., setting a second indoor unit speed). This increases the control objective of raising the indoor temperature and achieving indoor-outdoor air exchange, without considering the anti-condensation effect. By setting different equipment control parameters before and after the anti-condensation function is activated, the risk of condensation at the fresh air inlet can be avoided, while improving ventilation and temperature control, thus enhancing the user experience.
[0056] Optionally, Figure 2 This is a flowchart of another anti-condensation control method for refrigeration equipment provided in Embodiment 1 of the present invention. Figure 1 Based on this, an exemplary implementation of a target control strategy is shown.
[0057] like Figure 2 As shown, the anti-condensation control method for this refrigeration equipment includes the following steps:
[0058] Step S1: Obtain indoor and outdoor environmental parameters.
[0059] Step S2: Determine the start / stop conditions for the anti-condensation function of the fresh air unit based on outdoor environmental parameters.
[0060] Step S301: Obtain the absolute value of the deviation between indoor environmental parameters and outdoor environmental parameters.
[0061] For example, the absolute value of the deviation can be the deviation between indoor and outdoor ambient temperatures.
[0062] Step S302: Compare the absolute value of the deviation with the start-up and exit conditions, and determine the fresh air operation mode based on the comparison results.
[0063] For example, taking the absolute value of the indoor-outdoor temperature deviation as an example, the activation conditions include: the absolute value of the temperature deviation is greater than or equal to a first preset temperature threshold, and the duration reaches a first preset time; the exit conditions include: the absolute value of the temperature deviation is less than or equal to a second preset temperature threshold, and the duration reaches a second preset time. Wherein, the first preset temperature threshold is greater than the second preset temperature threshold.
[0064] It should be noted that the values of the first preset time and the second preset time can be set by calibration or based on experience, and there is no restriction on their specific values. For example, the first preset time can be set to equal the second preset time to equal 3 minutes.
[0065] Step S303: Determine the air conditioning compensation parameters based on the fresh air operation mode.
[0066] Among them, the air conditioning compensation parameter refers to the compensation value of the air conditioning control parameter. This compensation value can be any value that is greater than zero, less than zero, or equal to zero, and the value range of the air conditioning compensation parameter can be set to correspond to the fresh air operation mode.
[0067] Step S304: Compensate the preset air conditioning parameters according to the air conditioning compensation parameters to determine the equipment control parameters.
[0068] The preset air conditioning parameters are the air conditioning control parameters for independent operation of the air conditioning unit. Typically, air conditioning control parameters include, but are not limited to: the outdoor unit frequency and the indoor unit speed. Air conditioning compensation parameters include, but are not limited to: the outdoor unit compensation frequency and the indoor unit compensation speed.
[0069] Step S4: Control the operation of the fresh air unit according to the fresh air operation mode, and control the operation of the air conditioning unit according to the equipment control parameters.
[0070] Specifically, steps S301 to S304 above illustrate a specific implementation method for determining the target control strategy based on indoor environmental parameters, outdoor environmental parameters, and anti-condensation start / stop conditions. Taking temperature as an example, after obtaining the anti-condensation start and stop conditions corresponding to the current outdoor environmental temperature, the absolute value of the current indoor-outdoor temperature deviation is compared with the anti-condensation start and stop conditions. If the absolute value of the indoor-outdoor temperature deviation meets the anti-condensation start condition, the fresh air operation mode is determined to be the anti-condensation mode, and the air conditioning compensation parameter is set to be less than zero, i.e., the outdoor unit of the air conditioner is controlled to reduce its frequency operation level, and the indoor unit of the air conditioner is controlled to reduce its speed operation level. If the absolute value of the indoor-outdoor temperature deviation meets the anti-condensation stop condition, the fresh air operation mode is determined to be the non-anti-condensation mode, and the air conditioning compensation parameter is set to be greater than zero, i.e., the outdoor unit of the air conditioner is controlled to reduce its frequency operation level, and the indoor unit of the air conditioner is controlled to increase its speed operation level.
[0071] Therefore, by detecting the difference in indoor and outdoor environmental parameters, it is determined whether to activate the fresh air anti-condensation function, and the air conditioning control parameters are adjusted according to the trigger status of the anti-condensation function. Through the compensation adjustment of the control parameters, the air exchange and temperature regulation effects are improved while avoiding the generation of condensation water at the fresh air inlet, maintaining indoor temperature and humidity comfort, and enhancing the user experience.
[0072] In some embodiments, the value of the activation condition is negatively correlated with the outdoor environmental parameter; the value of the deactivation condition is also negatively correlated with the outdoor environmental parameter.
[0073] Specifically, the smaller the outdoor environmental parameters, the larger the values of the threshold parameters in the start and stop conditions. The outdoor environmental parameters can be segmented to obtain multiple preset environmental parameter segments, and a corresponding set of start and stop conditions can be set for each preset environmental parameter segment.
[0074] For example, taking the establishment of start-up and stop conditions based on outdoor ambient temperature as an example, the outdoor ambient temperature is defined as ORT and the indoor ambient temperature as RT. The correspondence between different preset temperature ranges and anti-condensation start-up and stop conditions is recorded, and a set of anti-condensation start-up and stop conditions list shown in Table 1 is established.
[0075]
[0076] As shown in Table 1, the outdoor ambient temperature is segmented to obtain multiple preset temperature segments. The threshold parameters for the anti-condensation start and stop conditions are different for each preset temperature segment. The lower the outdoor ambient temperature, the larger the value of the threshold parameter in the anti-condensation start and stop conditions.
[0077] As shown in Table 1, when the outdoor ambient temperature ORT meets the condition of 15℃ > ORT ≥ 5℃, the threshold parameter for the activation condition is set to 10℃, and the threshold parameter for the deactivation condition is set to 8℃. If the outdoor ambient temperature ORT meets the condition of 15℃ > ORT ≥ 5℃, and the absolute value of the temperature deviation between the indoor ambient temperature RT and the outdoor ambient temperature ORT is greater than or equal to 10℃, then the anti-condensation activation condition is met, and the system enters the anti-condensation mode. If the outdoor ambient temperature ORT meets the condition of 15℃ > ORT ≥ 5℃, and the absolute value of the temperature deviation between the indoor ambient temperature RT and the outdoor ambient temperature ORT is less than or equal to 8℃, then the anti-condensation deactivation condition is met, and the system enters the non-anti-condensation mode.
[0078] When the outdoor ambient temperature ORT meets the condition of 5℃ > ORT ≥ 0℃, the threshold parameter for the activation condition is set to 13℃, and the threshold parameter for the deactivation condition is set to 10℃. If the outdoor ambient temperature ORT meets the condition of 5℃ > ORT ≥ 0℃, and the absolute value of the temperature deviation between the indoor ambient temperature RT and the outdoor ambient temperature ORT is greater than or equal to 13℃, then the anti-condensation activation condition is met, and the system enters the anti-condensation mode. If the outdoor ambient temperature ORT meets the condition of 5℃ > ORT ≥ 0℃, and the absolute value of the temperature deviation between the indoor ambient temperature RT and the outdoor ambient temperature ORT is less than or equal to 10℃, then the anti-condensation deactivation condition is met, and the system enters the non-anti-condensation mode.
[0079] Similarly, by referring to a table based on the outdoor ambient temperature to obtain the corresponding anti-condensation start / stop conditions, it is beneficial to optimize the anti-condensation triggering function and avoid malfunctions of the anti-condensation function that could affect the user experience of the equipment.
[0080] For example, if the first temperature sensor detects that the current indoor ambient temperature RT is 7℃ and the second temperature sensor detects that the outdoor ambient temperature ORT is 4℃; at this time, RT-0RT=3℃<10℃, and the condition is met for 3 minutes, that is, the absolute value of the temperature deviation between the indoor ambient temperature RT and the outdoor ambient temperature ORT meets the anti-condensation exit condition, and the fresh air device is controlled to enter the non-anti-condensation mode; the fresh air device executes the start command, the fresh air fan component starts, the fresh air preheating component starts, and the indoor air is exchanged and preheated; the outdoor unit of the air conditioner increases the frequency operation level, for example, from the original 85Hz to 90Hz; the indoor unit of the air conditioner increases the speed operation level, for example, from the original 1250RPM to 1300RPM; through the compensation and adjustment of various parameters, the air volume and outlet temperature of the air conditioner are increased, the indoor temperature is rapidly increased, and the indoor and outdoor air circulation and exchange are realized to ensure that the indoor air is fresh and clean.
[0081] After continuous operation for a period of time (e.g., 30 minutes), if the first temperature sensor detects that the current indoor ambient temperature RT is 17℃ and the second temperature sensor detects that the current outdoor ambient temperature ORT is 4℃; at this time, RT-0RT=13℃=13℃, and this condition is met for 3 minutes, that is, the absolute value of the temperature deviation between the indoor ambient temperature RT and the outdoor ambient temperature ORT meets the anti-condensation activation condition, and the fresh air device is controlled to enter the anti-condensation mode; the fresh air device executes the shutdown command, the fresh air fan component shuts down, the fresh air preheating component shuts down, the outdoor unit of the air conditioner reduces its frequency operation level, and the compensation value is canceled or a negative compensation value is applied, for example, restoring the frequency of the outdoor unit of the air conditioner to the original 85Hz frequency level; the indoor unit of the air conditioner reduces its original speed operation level, and the compensation value is canceled or a negative compensation value is applied, for example, restoring the speed of the indoor unit of the air conditioner to the original 1250RPM; by canceling or applying negative compensation values to the compensation of each parameter, the air volume and air temperature of the air conditioner are reduced, the difference between indoor and outdoor environmental parameters is reduced, and the risk of condensation at the fresh air inlet is avoided.
[0082] Example 2
[0083] Optionally, Figure 3 The flowchart of a refrigeration equipment anti-condensation control method provided in Embodiment 2 of the present invention shows a specific implementation method based on preheating power adjustment to achieve the anti-condensation function, based on Embodiment 1.
[0084] like Figure 3 As shown, the anti-condensation control method for this refrigeration equipment includes the following steps:
[0085] Step S310: Obtain indoor and outdoor environmental parameters.
[0086] Step S320: Determine the anti-condensation start / stop conditions of the fresh air unit based on outdoor environmental parameters.
[0087] Step S330: Determine the target control strategy for the refrigeration equipment based on indoor environmental parameters, outdoor environmental parameters, and anti-condensation start-up and shutdown conditions.
[0088] Step S340: Determine the preheating power based on outdoor environmental parameters and / or indoor environmental parameters.
[0089] Step S350: Adjust the heating power of the fresh air preheating component according to the preheating power.
[0090] Step S360: Control the operation of the air conditioning unit according to the equipment control parameters.
[0091] Specifically, when the fresh air system operates in anti-condensation mode, the preheating power can be set to zero, controlling the fresh air fan components to shut down. When operating in anti-condensation mode, the preheating power can be determined based on outdoor environmental parameters or the difference between indoor and outdoor environmental parameters. For example, when the outdoor temperature is low or the temperature difference between indoor and outdoor environments is large, the preheating power can be set to a low value, controlling the fresh air preset components to preheat at a low power level. By adjusting the fresh air preheating power, condensation caused by the temperature difference between the inside and outside of the fresh air system during startup is avoided, further optimizing the anti-condensation effect and improving the user experience.
[0092] Example 3
[0093] Optionally, Figure 4 The flowchart of a refrigeration equipment anti-condensation control method provided in Embodiment 3 of the present invention shows a specific implementation method based on external commands to realize the anti-condensation function, based on Embodiment 1.
[0094] like Figure 4 As shown, the anti-condensation control method for this refrigeration equipment includes the following steps:
[0095] Step S410: Obtain indoor and outdoor environmental parameters.
[0096] Step S420: Determine the anti-condensation start / stop conditions of the fresh air unit based on outdoor environmental parameters.
[0097] Step S430: Determine the target control strategy for the refrigeration equipment based on indoor environmental parameters, outdoor environmental parameters, and anti-condensation start-up and shutdown conditions.
[0098] Step S440: Obtain remote operation instructions and local operation instructions.
[0099] Among them, remote operation instructions can be operation instructions sent by the user to the local controller through a smart terminal device; local operation instructions can be operation instructions input by the user through the I / O interface of the local controller or other hardware devices.
[0100] In some embodiments, the hardware device includes, but is not limited to, circuit components and audio components; the I / O interface can be used to connect peripheral touch components, such as click wheels or buttons.
[0101] Step S450: Adjust the fresh air operation mode and equipment control parameters according to remote operation instructions and / or local operation instructions.
[0102] Step S460: Control the operation of the fresh air unit according to the fresh air operation mode, and control the operation of the air conditioning unit according to the equipment control parameters.
[0103] Specifically, during the operation of the refrigeration equipment, users can input operation commands through smart terminals or hardware interfaces connected to the local controller to adjust the fresh air operation mode and equipment control parameters, enabling the refrigeration equipment to perform ventilation and temperature regulation functions according to the user's actual needs. Adding wireless communication and peripheral operation functions enhances the level of intelligence, and the diversified sources of operation commands improve operational reliability and enrich the user experience.

[0107] like Figure 5 As shown, the anti-condensation control device 00 for refrigeration equipment includes: a parameter acquisition module 101, used to acquire indoor environmental parameters and outdoor environmental parameters, and determine the anti-condensation start / stop conditions of the fresh air unit based on the outdoor environmental parameters; a decision module 102, used to determine the target control strategy of the refrigeration equipment based on the indoor environmental parameters, outdoor environmental parameters, and the anti-condensation start / stop conditions; wherein, the target control strategy includes at least: a fresh air operation mode and equipment control parameters, and the fresh air operation mode includes at least: an anti-condensation mode and a non-anti-condensation mode; and an execution module 103, used to control the operation of the fresh air unit according to the fresh air operation mode, and control the operation of the air conditioning unit according to the equipment control parameters.
[0108] Specifically, during the simultaneous operation of the air conditioning unit and the fresh air unit, the parameter acquisition module 101 detects the indoor and outdoor environmental parameters in real time and obtains the anti-condensation start and stop conditions corresponding to the current outdoor environmental parameters. The decision module 102 determines the target control strategy for the cooling equipment based on indoor environmental parameters, outdoor environmental parameters, and anti-condensation start / stop conditions. If the current indoor and outdoor environmental parameters meet the current anti-condensation start conditions, the decision module 102 sets the fresh air operation mode to the anti-condensation mode and sets the equipment control parameters to the corresponding anti-condensation mode. The execution module 103 controls the fresh air fan assembly and fresh air preheating assembly to shut down, while reducing the air volume and outlet temperature of the air conditioning unit to reduce the difference between indoor and outdoor environmental parameters and avoid the risk of condensation at the fresh air inlet. If the current indoor and outdoor environmental parameters do not meet the current anti-condensation start conditions, the decision module 102 sets the fresh air operation mode to the non-anti-condensation mode and sets the equipment control parameters to the corresponding non-anti-condensation mode. The execution module 103 controls the fresh air fan assembly and fresh air preheating assembly to start, while increasing the air volume and outlet temperature of the air conditioning unit to raise the indoor temperature and achieve indoor and outdoor air exchange, without considering the anti-condensation effect. By detecting differences in indoor and outdoor environmental parameters, the system adjusts the fresh air operation mode and equipment control parameters in real time, solving the problem that existing fresh air conditioners are prone to condensation during heating, which harms user interests and results in a poor user experience. It avoids the risk of condensation at the fresh air inlet, improves ventilation and temperature regulation, maintains indoor temperature and humidity comfort, and enhances the user experience.
[0109] In this application, the parameter acquisition module 101 includes a first temperature sensor and a second temperature sensor, wherein the first temperature sensor is used to acquire the indoor ambient temperature; and the second temperature sensor is used to acquire the outdoor ambient temperature.
[0110] In this application, the refrigeration equipment includes a fresh air unit and an air conditioning unit.
[0111] Optionally, Figure 6 This is a schematic diagram of a fresh air device provided in Embodiment 4 of the present invention.
[0112] like Figure 6 As shown, the fresh air system includes a fresh air duct 10, a fresh air fan assembly 20, a fresh air preheating assembly 30, and a fresh air filter 40. The fresh air duct 10 has an air inlet A and an air outlet B. The fresh air fan assembly 20 is located inside the fresh air duct 10 and draws outdoor air into the fresh air duct 10 from the air inlet A. After being preheated by the fresh air preheating assembly 30, the air is blown into the room from the air outlet B.
[0113] Specifically, when the fresh air system enters the anti-condensation mode, the fresh air fan assembly 20 and the fresh air preheating assembly 30 are turned off; when the fresh air system enters the non-anti-condensation mode, the fresh air system start command is executed, and the fresh air fan assembly 20 and the fresh air preheating assembly 30 are turned on to pre-treat the air entering the room from the outside. The air is then directly sent into the room through the independent fresh air duct 10. The fresh air is mixed with the indoor supply air and then enters the return air vent. After being processed by the indoor air conditioning unit, it is sent into the room, thereby realizing the circulation and exchange of indoor and outdoor air and ensuring that the indoor air is fresh and clean.
[0114] In some embodiments, the first temperature sensor may be located at the air inlet A.
[0115] In some embodiments, the fresh air preheating component 30 includes, but is not limited to, an electric heating component consisting of a PTC heater, a thermal relay, a thermal fuse, a mounting bracket, and other accessories.
[0116] In some embodiments, the fresh air filter 40 can use a HEPA filter, which has a purification rate of up to 99.7% for particles of 0.1 microns and 0.3 microns. Air can pass through the HEPA filter, but fine particles cannot. Therefore, it is most effective in preventing smog and filtering PM2.5 and PM0.1 particles, while also capturing mold, bacteria, viruses, etc. When used in places with poor air quality, it can effectively protect respiratory health.
