Description

Technical Field

[0001] The present invention relates to the field of refrigeration technology, and in particular to a refrigeration device and a control method, a control device, and a computer-readable storage medium thereof. Background Art

[0002] The condenser of a traditional refrigerator is installed on both sides of the refrigerator. However, the condenser needs to dissipate heat during operation, which will affect the insulation effect of the refrigerator and cause fluctuations in the temperature of the room. Therefore, a bottom-mounted condenser solution is adopted, in which the condenser is placed in the compressor compartment, and a condensing fan is added to dissipate heat from the compressor compartment. Since dust in the environment is inevitable, dust will form deposits on the condenser during the process of the condensing fan blowing air to the condenser to dissipate heat. When the condenser is dusty, the performance of the condenser and the overall refrigeration system will be attenuated. That is, although the refrigerator compartments can still be cooled, the energy consumption, freezing capacity and other performance of the refrigerator will be significantly deteriorated. After dust accumulation, the energy consumption of the whole machine increases, and the average temperature of the freezer compartment increases, which seriously affects the refrigerator's refrigeration effect and user experience.

[0043] The condenser of a traditional refrigerator is installed on both sides of the refrigerator. However, the condenser needs to dissipate heat during operation, which will affect the insulation effect of the refrigerator and cause fluctuations in the temperature of the room. Therefore, a bottom-mounted condenser solution is adopted, in which the condenser is placed in the compressor compartment, and a condensing fan is added to dissipate heat from the compressor compartment. Since dust in the environment is inevitable, dust will form deposits on the condenser during the process of the condensing fan blowing air to the condenser to dissipate heat. When the condenser is dusty, the performance of the condenser and the overall refrigeration system will be attenuated. That is, although the refrigerator compartments can still be cooled, the energy consumption, freezing capacity and other performance of the refrigerator will be significantly deteriorated. After dust accumulation, the energy consumption of the whole machine increases, and the average temperature of the freezer compartment increases, which seriously affects the refrigerator's refrigeration effect and user experience.

[0044] To this end, the present application provides a Figures 1 to 4 The control method of the refrigeration equipment shown in the figure, the refrigeration equipment includes a heat exchanger 1 and a compressor, the heat exchanger 1 is connected to the compressor, and the compressor has a resonant speed that resonates with the heat exchanger 1. The control method includes: judging whether the refrigeration equipment needs to remove dust from the heat exchanger 1; if so, controlling the refrigeration equipment to switch to the resonant speed. The compressor is switched to the resonant frequency so that the compressor and the heat exchanger 1 resonate, so that the dust on the heat exchanger 1 can be removed by vibration, and the dust removal effect of the heat exchanger 1 is achieved, which effectively improves the refrigeration effect of the refrigeration equipment and prolongs the service life of the refrigeration equipment. The compressor has multiple set speeds. At these set speeds, the compressor can perform a normal compression process, and the compressor will cause different vibrations in the connected structure at different speeds. At this time, the resonant speed at which the compressor can drive the heat exchanger 1 to resonate is determined. When the heat exchanger 1 needs to be dusted, the compressor can be switched to this resonant speed so that the dust on the fins of the heat exchanger 1 is shaken off to achieve a better refrigeration effect. For example, when the refrigeration equipment is operating normally, the speed of the compressor can be 1200rpm, 1500rpm, 1800rpm, etc. Normal refrigeration is performed at these speeds, which is called the set speed. Through testing, it can be concluded that during the operation of the refrigeration equipment, a resonance relationship may exist between the compressor and the heat exchanger 1. Resonance can be achieved at this speed, which allows the condenser to vibrate together with the compressor, thereby achieving a dust removal effect. Assume that the resonant speed is 1620rpm, that is, when the compressor runs at 1620rpm, the heat exchanger 1 can resonate with it.

[0045] In determining whether the refrigeration equipment needs to remove dust from the heat exchanger 1, the control method further includes:

[0046] Obtain the continuous working time t1 of the refrigeration equipment, and compare t1 with the preset working time t0;

[0047] If t1≥t0, it indicates that a certain amount of dust has adhered to the heat exchanger 1 at this time, and it is determined that the refrigeration equipment needs to remove dust from the heat exchanger 1. At this time, the compressor can be switched to the resonant speed, and the vibration of the heat exchanger 1 can be used to achieve efficient dust removal. The short-term switching of the compressor to the resonant speed will not affect the refrigeration effect of the refrigeration equipment.

[0048] The numerical range of the preset working time is 3 days to 14 days, and preferably, the preset working time is 7 days.

[0049] Since the compressor needs to be switched to the resonant speed, the refrigeration effect of the refrigeration equipment will still be affected at this time. Therefore, before obtaining the continuous working time t1 of the refrigeration equipment, the control method further includes:

[0050] Obtain the ambient temperature T1 of the environment where the refrigerator is located, and compare T1 with the preset temperature T0;

[0051] If T1<T0, the reduction in the refrigeration effect of the refrigeration equipment will not affect the storage effect of the refrigeration equipment, and the step of detecting the continuous working time t1 of the refrigeration equipment can be performed.

[0052] Furthermore, the refrigeration equipment also includes a vibrator 2, and the vibrator 2 is arranged on the heat exchanger 1. After determining whether the refrigeration equipment needs to remove dust from the heat exchanger 1, the control method also includes: controlling the vibrator 2 to work so as to drive the heat exchanger 1 to vibrate, that is, on the basis of switching the compressor to the resonant speed, controlling the vibrator 2 to work, so that the heat exchanger 1 is driven by the resonance of the compressor and the vibration of the vibrator 2 at the same time, thereby improving the technical effect of removing dust on the heat exchanger 1.

[0053] Optionally, the vibrator 2 has a first vibration frequency and a second vibration frequency, the second vibration frequency is higher than the first vibration frequency, and after determining whether the refrigeration equipment needs to remove dust from the heat exchanger 1, the vibrator 2 is controlled to switch to the second vibration frequency. That is, at this time, the vibrator 2 is turned on to a higher gear, the vibration drive of the heat exchanger 1 is increased, and the dust removal effect of the heat exchanger 1 is improved.

[0054] In order to ensure the heat dissipation effect of the heat exchanger 1, the refrigeration equipment also includes a cooling fan. The airflow of the cooling fan can flow through the heat exchanger 1, thereby ensuring the heat dissipation effect of the heat exchanger 1, and the cooling fan has at least two working speeds. When the refrigeration equipment is controlled to switch to the resonant speed, the cooling fan switches to the lowest working speed. Since the speed of the compressor is not high and the ambient temperature has not reached a high temperature, the low-efficiency operation of the condensing fan in a short period of time has little effect on the heat dissipation of the heat exchanger 1 and will not affect the reliability of the refrigeration equipment.

[0055] Among them, when T1<T0, if the refrigeration equipment enters the strong cooling stage during the defrosting process, the compressor is at the maximum set speed, and the cooling fan is also at the highest operating speed. The airflow driven by the cooling fan can blow off the dust on the heat exchanger 1, and can also achieve the dust removal effect on the heat exchanger 1. At this time, the vibrator 2 can be kept stopped to reduce the energy consumption of the refrigeration equipment.

[0056] Furthermore, the refrigeration device further includes a vibrator 2, and the vibrator 2 is arranged on the heat exchanger 1. After obtaining the ambient temperature T1 of the environment in which the refrigerator is located and comparing T1 with the preset temperature T0, the control method further includes:

[0057] If T1≥T0, it indicates that the ambient temperature is relatively high at this time. When the refrigeration equipment is working, as long as the compressor is working, the heat exchanger 1 needs to dissipate heat. At this time, the cooling fan always maintains a relatively high working speed to dissipate heat for the heat exchanger 1. Therefore, the dust on the heat exchanger 1 can be blown up by the cooling fan. At this time, the heat exchanger 1 does not need to be dusted. Only when the refrigeration equipment is in the strong cooling stage during the defrosting process, the vibrator 2 is controlled to work to drive the heat exchanger 1 to vibrate. At this time, in order to ensure the refrigeration effect, the refrigeration equipment will switch the compressor to the highest set speed for operation, and the cooling fan will also switch to the maximum working speed for heat dissipation. However, by vibrating the heat exchanger 1, the dust removal effect of the heat exchanger 1 is further increased. At the same time, since the noise generated by the compressor and the cooling fan is the largest at this time, the noise generated by the vibration of the vibrator 2 and the heat exchanger 1 is not obvious, which can not only achieve the purpose of dust removal for the heat exchanger 1, but also improve the user experience.

[0058] The vibrator 2 has a first vibration frequency and a second vibration frequency, the second vibration frequency is higher than the first vibration frequency. When the refrigeration equipment is in the strong cooling stage during the defrosting process, the vibrator 2 is controlled to switch to the second vibration frequency. Since the noise generated by the compressor and the cooling fan is the largest, the noise generated by the vibration of the vibrator 2 and the heat exchanger 1 is not obvious. At this time, the vibrator 2 is switched to the higher second vibration frequency, and the noise generated will not have a significant impact. It can also improve the dust removal effect on the heat exchanger 1, thereby improving the user experience.

[0059] Furthermore, the refrigeration device further includes a vibrator 2, and the vibrator 2 is arranged on the heat exchanger 1. After obtaining the ambient temperature T1 of the environment in which the refrigerator is located and comparing T1 with the preset temperature T0, the control method further includes:

[0060] If T1≥T0, then after the compressor stops, the heat exchanger 1 does not need to dissipate heat, that is, the cooling fan stops running. In order to ensure dust removal of the heat exchanger 1, the vibrator 2 is controlled to work continuously for the first time period to shake off the dust on the heat exchanger 1. At this time, the cooling fan stops running, and the dust will not be lifted up and fall onto the heat exchanger 1 again, thereby ensuring the dust removal effect of the heat exchanger 1.

[0061] The vibrator 2 has a first vibration frequency and a second vibration frequency, wherein the second vibration frequency is higher than the first vibration frequency. After the compressor stops, the vibrator 2 is controlled to continuously operate at the first vibration frequency for a first period of time. The lower first vibration frequency is used to reduce the noise generated by the vibration of the vibrator 2 and the heat exchanger 1, thereby improving the user experience.

[0062] The first time period ranges from 5 minutes to 15 minutes, preferably 10 minutes. When the first time period is less than 5 minutes, the vibration time of the vibrator 2 on the heat exchanger 1 is shorter, and the dust removal effect is poor. When the first time period is greater than 10 minutes, the vibration time of the heat exchanger 1 is longer. Although the dust removal effect is good, the noise is generated for a longer time and affects the user experience.

[0063] The preset temperature T0 has a value range of 20°C to 35°C, and preferably, the preset temperature T0 is 30°C.
