Description

Technical Field

[0001] This application relates to the field of air conditioning control technology, and in particular to an air conditioning control method and device. Background Technology

[0002] When an air conditioning system is operating in low-temperature heating mode, the refrigerant temperature entering the condenser is relatively low, making the condenser prone to frost formation. Defrosting is then necessary. Current technology commonly uses reverse defrosting, which requires the indoor unit to stop and uses a four-way valve to switch to outdoor unit heating for defrosting. The shutdown of the indoor unit causes fluctuations in indoor temperature, affecting the customer experience. Conversely, when the air conditioning system is operating in high-temperature cooling mode, the high outdoor temperature causes significant system pressure, leading to the inverter compressor reducing its frequency or the fixed-frequency compressor shutting down. This results in poorer cooling performance, also impacting the user experience. Summary of the Invention

[0037] To more clearly illustrate the technical solutions in this embodiment or the prior art, the drawings used in the description of the embodiment or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0040] Figure 3 This is a schematic diagram of the structure of an air conditioning control device provided in an embodiment of this application. Detailed Implementation

[0041] When an air conditioning system is operating in low-temperature heating mode, the refrigerant temperature entering the condenser is relatively low, making the condenser prone to frost formation. Defrosting is then necessary. Current technology commonly uses reverse defrosting, which requires the indoor unit to stop and uses a four-way valve to switch to outdoor unit heating for defrosting. The shutdown of the indoor unit causes fluctuations in indoor temperature, affecting the customer experience. Conversely, when the air conditioning system is operating in high-temperature cooling mode, the high outdoor temperature causes significant system pressure, leading to the inverter compressor reducing its frequency or the fixed-frequency compressor shutting down. This results in poorer cooling performance, also impacting the user experience.

[0042] In view of this, the inventors of this application considered that if an auxiliary heating device is used to turn on when the inlet liquid temperature is detected to raise the inlet liquid temperature for defrosting the machine, and the low temperature of the gas-liquid separator is used to reduce the temperature of the refrigerant entering the condenser during high-temperature refrigeration, thereby reducing the system high pressure and achieving compressor frequency maintenance and non-stop operation, the above problems can be solved.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0044] See Figure 1 , Figure 1 The diagram illustrates the principle of an air conditioning control method provided in this application embodiment. In the low-temperature heating mode, when the outdoor unit of the air conditioner is frosted, the refrigerant entering the condenser first enters the compressor, then passes through the four-way reversing valve, and then enters the evaporator. At this time, the one-way valve is closed. Then it passes through the electronic expansion mesh, and is heated by the electromagnetic heating coil before finally entering the condenser. This method achieves defrosting of the outdoor unit of the air conditioner without the need to stop the machine.

[0045] When the air conditioner is in high-temperature cooling mode, and the outdoor ambient temperature or indoor ambient temperature is detected to be higher than the preset temperature, the solenoid valve is opened. The refrigerant first enters the compressor, and then passes through the four-way reversing valve. Since the solenoid valve is open, the refrigerant passes through the four-way reversing valve and then through the solenoid valve to enter the gas-liquid separator for heat exchange, reducing the temperature of the refrigerant. Then it enters the condenser, then through the electronic expansion valve, and finally enters the evaporator, thereby reducing the gas pressure of the system and preventing the inverter compressor or the fixed-frequency compressor from stopping.

[0046] See Figure 2 , Figure 2 A flowchart of an air conditioning control method provided in this application embodiment includes:

[0047] S201. Determine whether the condenser meets the first condition, where the first condition is that the condenser is frosted.

[0048] In low-temperature heating mode, air conditioners are prone to frost buildup on the condenser. There are several scenarios to determine if the condenser is frosted: First, if the outdoor ambient temperature (Tao) is greater than a first threshold and the defrost sensor temperature (Te) is less than or equal to a second threshold, then the condenser is considered frosted. The first threshold can be 5°C, and the second threshold can be -4°C. Second, if the outdoor ambient temperature is greater than or equal to a third threshold and less than or equal to the first threshold, and the defrost sensor temperature is less than or equal to a fourth threshold, the third threshold can be -6°C, and the fourth threshold can be -8°C. Third, if the outdoor ambient temperature is greater than a fifth threshold and less than the third threshold, and the defrost sensor temperature is less than or equal to a sixth threshold, the fifth threshold can be -15°C, and the sixth threshold can be -18°C. Fourth, if the outdoor ambient temperature is less than or equal to the fifth threshold. These thresholds can be set according to actual conditions, ensuring that the first threshold is greater than the third threshold, the fourth threshold is less than the second threshold, the third threshold is greater than the fifth threshold, and the sixth threshold is less than the fourth threshold.

[0049] S202. If the condenser meets the first condition, then the refrigerant introduced into the condenser is heated by using an electromagnetic heating coil.

[0050] When frost is detected on the condenser, an electromagnetic heating coil is used to heat the refrigerant flowing into the condenser in order to defrost it.

[0051] For example, if the condenser meets the first condition, the refrigerant flowing into the condenser can be heated using an electromagnetic heating coil, with a maximum operating time of 10 minutes; if the condenser meets the second condition, the refrigerant flowing into the condenser can also be heated using an electromagnetic heating coil, with a maximum operating time of 10 minutes; if the condenser meets the third condition, the refrigerant flowing into the condenser can also be heated using an electromagnetic heating coil, with a maximum operating time of 10 minutes; if the condenser meets the fourth condition, a timed heating method can be used, for example, it can be turned on once every 3 hours, using an electromagnetic heating coil to heat the refrigerant flowing into the condenser, with a maximum operating time of 10 minutes.

[0052] S203. Determine whether the condenser meets the second condition, wherein the second condition is that the outdoor ambient temperature is greater than the first preset temperature or the defrost sensor temperature is greater than the second preset temperature.

[0053] When an air conditioner is in high-temperature cooling mode, the high-temperature, high-pressure gas it produces can easily cause the inverter compressor to reduce its frequency or the fixed-frequency compressor to stop. In this case, it's necessary to determine whether the outdoor ambient temperature is higher than the first preset temperature or whether the defrost sensor temperature is higher than the second preset temperature, specifically whether Tao is greater than 53℃ and Te is greater than 56℃. The first and second preset temperatures can be set as needed.

[0054] S204. If the condenser meets the second condition, the refrigerant introduced into the condenser is cooled using a gas-liquid separator.

[0055] If the condenser meets the condition that the outdoor ambient temperature is greater than a first preset temperature or the defrost sensor temperature is greater than a second preset temperature, the refrigerant introduced into the condenser can be cooled using a gas-liquid separator. Specifically, this can be determined by detecting the temperature of the sensor in the middle of the condenser. Figure 1 The opening condition of the solenoid valve is that the connection between the refrigerant and the gas-liquid separation device can only be realized after the solenoid valve is opened. The condition for determining the opening of the solenoid valve is also the second condition.

[0056] A specific cooling method is to introduce refrigerant into a heat exchange device, where it exchanges heat with the surface of the gas-liquid separator to achieve a cooling effect.

[0057] This application provides an air conditioning control method. When executing the method, firstly, it is determined whether the condenser meets a first condition, which is that the condenser is frosted. If the condenser meets the first condition, an electromagnetic heating coil is used to heat the refrigerant flowing into the condenser. Then, it is determined whether the condenser meets a second condition, which is that the outdoor ambient temperature is greater than a first preset temperature or the defrost sensor temperature is greater than a second preset temperature. If the condenser meets the second condition, a gas-liquid separator is used to cool the refrigerant flowing into the condenser. Thus, when the condenser is frosted, the electromagnetic heating coil heats the refrigerant entering the condenser to defrost the machine, achieving a defrosting effect without stopping the machine, compared to the existing reverse-cycle defrosting method. When the outdoor ambient temperature is greater than the first preset temperature or the defrost sensor temperature is greater than the second preset temperature, the gas-liquid separator cools the refrigerant flowing into the condenser, reducing the system pressure during high-temperature cooling and preventing the inverter compressor from reducing its frequency or the fixed-frequency compressor from stopping. This solves the problem of poor user experience caused by shutdowns during low-temperature heating defrosting or high-temperature cooling operation in existing air conditioning systems.

[0058] In an optional embodiment of this application, when heating the refrigerant introduced into the condenser using an electromagnetic heating coil, the frequency of the compressor can be adjusted according to the outdoor ambient temperature and the fan speed. The specific adjustment parameters are shown in Table 1, where Tao is the outdoor ambient temperature.

Based on this, this application also provides a corresponding air conditioning control device. The device provided in this application will be described below from the perspective of functional modularity.

[0063] The first judgment module 301 is used to determine whether the condenser meets the first condition, the first condition being that the condenser is frosted;

[0064] If the condenser meets the first condition, the heating module 302 is used to heat the refrigerant introduced into the condenser using an electromagnetic heating coil;

[0065] The second judgment module 303 is used to determine whether the condenser meets the second condition, which is that the outdoor ambient temperature is greater than the first preset temperature or the defrost sensor temperature is greater than the second preset temperature.

[0066] If the condenser meets the second condition, the cooling module 304 is used to cool the refrigerant introduced into the condenser using a gas-liquid separator.

[0067] This application provides an air conditioning control device for executing a corresponding air conditioning control method.

If the condenser meets the second condition, a gas-liquid separator is used to cool the refrigerant flowing into the condenser. In this way, when the condenser frosts, the refrigerant entering the condenser is heated by an electromagnetic heating coil to defrost the machine. Compared with the existing technology that uses reverse circulation defrosting, this achieves a defrosting effect without stopping the machine. When the outdoor ambient temperature is higher than the first preset temperature or the defrost sensor temperature is higher than the second preset temperature, the gas-liquid separator is used to cool the refrigerant entering the condenser, reducing the system pressure during high-temperature cooling and preventing the inverter compressor from reducing its frequency or the fixed-frequency compressor from shutting down.

[0071] Alternatively, if the outdoor ambient temperature is greater than the fifth threshold and less than the third threshold, and the defrost sensor temperature is less than or equal to the sixth threshold, then the condenser is considered to be frosted; wherein the third threshold is greater than the fifth threshold, and the sixth threshold is less than the fourth threshold;

[0072] Alternatively, if the outdoor ambient temperature is less than or equal to the fifth threshold, the condenser is considered to be frosted.

[0074] If the outdoor ambient temperature is less than or equal to the fifth threshold, it is considered that after the condenser frosts, a timed heating method is used to heat the refrigerant introduced into the condenser using an electromagnetic heating coil.
