Description

TECHNICAL FIELD

[0001] The present application relates to the field of computer control of heat pump equipment, and particularly relates to a condensation prevention regulation method, a heat pump system, a device and a storage medium. BACKGROUND

[0002] The existing heat pump system usually comprises a heat releasing device, a compressor module, a heat absorbing device and a control module. The heat releasing device, the compressor module and the heat absorbing device can be provided with a gas refrigerant transmission pipeline. When the refrigerant with low temperature passes through the heat absorbing device, the heat absorbing device can absorb heat from the heat source. The refrigerant carrying heat passes through the compressor module to be pressurized to form a high-temperature and high-pressure state. At this time, the refrigerant can release heat when passing through the heat releasing device placed in the room to provide heating for the room. After passing through the heat releasing device, the refrigerant becomes low-temperature again. The control module is provided with a control board and a power board to provide power for the compressor module and control the operation of the compressor module. Therefore, the control module itself will also generate heat, which needs to be cooled in time. In the past, ambient air flow is used to cool the control module. However, the cooling effect has limitations.

[0003] Later, some manufacturers set a cooling refrigerant pipe in the control module. The refrigerant after passing through the heat releasing device is input into the cooling refrigerant pipe and then output to the compressor module. Since the refrigerant after passing through the heat releasing device has low temperature, it can cool the control module. However, when the ambient temperature is high or the ambient humidity is high, the dew point temperature will be high. The temperature of the refrigerant passing through the cooling refrigerant pipe is higher than the dew point temperature and exceeds a certain range. The cooling refrigerant pipe will appear condensation or even frost, which can easily cause short circuit and damage of the elements on the surface of the control board and the power board. Therefore, the manufacturers need to set a complex condensation guide structure, but the effect is not good, and there is still a risk of large condensation drop. Or set a complex control logic to regulate the temperature of the refrigerant input into the cooling refrigerant pipe. However, the energy consumption of the heat pump system is significantly increased, and the cooling effect does not meet the requirements. SUMMARY

The output end of the heat absorbing device is connected with the input end of the compressor module. The output end of the compressor module is connected with the input end of the heat releasing device. The control module is connected with the first vortex pipe and the second vortex pipe to control the first valve core and the second valve core. The anti-condensation control method comprises the following steps:

[0006] Obtaining the dry-bulb temperature and the relative humidity, and obtaining the dew point temperature according to the dry-bulb temperature and the relative humidity;

[0007] Formulating the heat dissipation refrigerant temperature according to the dew point temperature. The heat dissipation refrigerant temperature is the temperature of the refrigerant output from the second hot gas outlet to the heat dissipation refrigerant pipe.

[0008] According to the heat dissipation refrigerant temperature, a heat dissipation refrigerant flow is obtained based on a preset heat dissipation temperature and flow relationship model, wherein the higher the heat dissipation refrigerant temperature, the greater the heat dissipation refrigerant flow, and the heat dissipation refrigerant flow is the flow of the refrigerant output from the second hot gas port to the heat dissipation refrigerant pipe;

[0049] As shown in Figure 4 The anti-condensation control method includes the following steps.

[0050] S510, obtaining the dry bulb temperature and the relative humidity, and obtaining the dew point temperature according to the dry bulb temperature and the relative humidity;

[0051] S520, determining the heat dissipation refrigerant temperature according to the dew point temperature, wherein the heat dissipation refrigerant temperature is the temperature of the refrigerant output from the second hot gas port 330 to the heat dissipation refrigerant pipe;

[0052] S530, obtaining the heat dissipation refrigerant flow rate based on the preset heat dissipation temperature and flow rate relationship model according to the heat dissipation refrigerant temperature, wherein the higher the heat dissipation refrigerant temperature, the greater the heat dissipation refrigerant flow rate, and the heat dissipation refrigerant flow rate is the flow rate of the refrigerant output from the second hot gas port 330 to the heat dissipation refrigerant pipe;

[0056] S570, obtaining the first hot gas flow of the first hot gas port 230 according to the first inlet temperature and the second inlet temperature;

[0057] S580, the control module 430 controls the first valve core 250 to operate to adjust the first hot gas flow.

[0058] It should be noted that in the refrigerant circulation loop of the heat pump system, the output end of the heat releasing device 110 outputs a fixed total refrigerant flow, and the refrigerant output from the output end of the heat releasing device 110 enters the first inlet port 220 of the first vortex tube 200, is separated into high-temperature refrigerant and low-temperature refrigerant, the high-temperature refrigerant is output from the first hot gas port 230, and the low-temperature refrigerant is output from the first cold gas port 240.

In some embodiments of the present application, the heat-removing refrigerant temperature can also be slightly lower than the dew point temperature, i.e., the sum of the heat-removing refrigerant temperature and an adaptive temperature value specified by a designer is equal to the dew point temperature. The heat-removing refrigerant temperature is lower, which can improve the heat-removing effect. However, the heat-removing refrigerant temperature cannot be excessively lower than the dew point temperature, so that the surface of the heat-removing refrigerant pipe cannot have excessive condensation.
