[0029] The optional embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] Example 1

[0031] According to an embodiment of the present invention, an embodiment of a method for determining the power consumption of a unit is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0032] Figure 1 is a flow chart of a method for determining power consumption of a unit according to an embodiment of the present invention. Figure 1 As shown, the method comprises the following steps:

[0033] Step S101, when the unit is in refrigeration operation, after the indoor temperature reaches a preset target temperature, the water outlet temperature and the air outlet temperature of the unit are detected;

[0034] Step S102, if the outlet water temperature changes, determine the current static pressure according to the outlet water temperature change trend and the fan gear position; if the outlet water temperature remains unchanged, if the air outlet temperature changes, determine the current static pressure according to the outlet outlet change trend and the fan gear position;

[0035] Step S103, calculating the power consumption of the computer group according to the fan gear position and the current static pressure.

[0036] This embodiment combines the unit's water outlet temperature, air outlet temperature, and fan gear to determine the unit's current static pressure, and then combines the factory setting data to determine the static pressure and the power corresponding to the fan gear. Based on this, accurate power consumption data of the fan disc unit is calculated. Users can also query the power consumption data in real time. The thermostat can thereby achieve more effective and accurate automatic intelligent adjustment of the unit, thereby improving the user experience of the air conditioner.

[0037] The outlet water temperature of this embodiment is the temperature of the outlet water pipe of the unit. The outlet water pipe and the refrigerant pipe in the outdoor unit are arranged in parallel. The water in the outlet water pipe can exchange heat with the refrigerant in the refrigerant pipe to achieve the cooling of the water temperature. The outlet water pipe is connected to the indoor unit, and the wind blown by the fan will pass through the outlet water pipe, which can achieve the cooling of the outlet air temperature.

[0038] In this embodiment, before leaving the factory, the fan unit is running stably. When the indoor temperature reaches the preset target temperature T 目标 ℃ (for example 26℃), detect the inlet water temperature T 进水 ℃ (e.g. 5℃), outlet water temperature T 出水 ℃ (e.g. 7℃), air inlet temperature T 进风 ℃ (e.g. 28℃), outlet temperature T 出风 ℃ (for example 26℃), the fan speed is N 目标温度 , the static pressure is measured as Apa and the power P A(The gear position has been determined at this time), the data is saved on the storage chip and is the factory data, such as Figure 2 The schematic diagram of the factory data of the unit is shown. That is, the factory data contains a mapping relationship between multiple fan gears and corresponding multiple static pressure gears, as well as the corresponding relationship between the two and power. For example, when the fan speed gear is the second gear and the static pressure is 12pa, the corresponding power under this operating condition is P8.

[0039] When the unit is turned on, the inlet and outlet water temperatures are set to the factory values. During the refrigeration operation of the unit, after the indoor temperature reaches the preset target temperature, it is determined whether the outlet water temperature has changed. Specifically, the outlet water temperature is compared with the factory value, for example, whether the difference between the two is less than the preset interval. If so, it is determined that the outlet water temperature has not changed. Otherwise, it is determined that the outlet water temperature has changed.

[0040] When the outlet water temperature is detected to have changed, the present embodiment determines the current static pressure according to the outlet water temperature change trend and the fan gear position. Specifically, if the outlet water temperature has changed, the number of gears of the fan gear position change is confirmed; the current static pressure is determined according to the outlet water temperature change trend and the number of gears of the fan gear position change. When the outlet water temperature of the unit changes, the gear of the fan speed will change accordingly, and the degree of change of the fan gear position can reflect the current static pressure. Therefore, the present embodiment determines the current static pressure according to the outlet water temperature change trend and the number of gears of the fan gear position change, so that the current static pressure value of the unit can be determined more accurately.

[0041] Under the condition of keeping the preset target temperature unchanged, the greater the static pressure, the greater the wind speed and the greater the power. When the outlet water temperature rises (from 5℃ to 8℃), the temperature of the wind blown out rises. At this time, the room temperature is higher than the preset target temperature. The fan gear is automatically adjusted according to the preset target temperature. Raising one gear will adjust the room temperature to approach the target temperature.

[0042] If the trend of the outlet water temperature is increasing, confirm the number of gears that the fan gear has increased, and determine the current static pressure based on the number of gears that have increased. Specifically, if the number of gears that has increased is one gear, determine that the current static pressure is the preset static pressure value; wherein, the preset static pressure value is the static pressure value corresponding to the unit when it is operating at the preset target temperature; if the number of gears that has increased is n gears, determine that the current static pressure is the static pressure value after the preset static pressure value is reduced by n static pressure gears; wherein, n is a positive integer, and there are preset multiple fan gears and corresponding multiple static pressure gears, and the determined current static pressure is not lower than the static pressure value of the lowest static pressure gear. Based on this, the current static pressure of the unit can be accurately identified according to the changes in the outlet water temperature and the changes in the fan gear, so that more accurate power consumption data can be obtained.

[0043] If the trend of the change in the outlet water temperature is decreasing, confirm the number of gears that the fan gear has been reduced, and determine the current static pressure based on the number of gears that have been reduced. Specifically, if the number of gears that has been reduced is one gear, determine that the current static pressure is the preset static pressure value; wherein, the preset static pressure value is the static pressure value corresponding to when the unit is operating at the preset target temperature; if the number of gears that has been reduced is n gears, determine that the current static pressure is the static pressure value after the preset static pressure value is increased by n static pressure gears; wherein, n is a positive integer, and there are preset multiple fan gears and corresponding multiple static pressure gears, and the determined current static pressure does not exceed the static pressure value of the highest static pressure gear. Based on this, the current static pressure of the unit can be accurately identified according to the changes in the outlet water temperature and the changes in the fan gear, so that more accurate power consumption data can be obtained.

[0044] If the outlet water temperature of the unit remains unchanged, if the fan gear is lowered, then the outlet temperature will drop, and if the fan gear is increased, then the outlet temperature will increase. Specifically, in this embodiment, when the outlet water temperature remains unchanged, if the outlet temperature changes, the current static pressure is determined according to the outlet change trend and the fan gear. Specifically, if the outlet temperature decreases and the fan gear is lowered, it is determined that the current static pressure is the static pressure value after the preset static pressure value is increased by 1 static pressure gear; if the outlet temperature increases and the fan gear is increased, it is determined that the current static pressure is the static pressure value after the preset static pressure value is reduced by 1 static pressure gear; wherein, the preset static pressure value is the static pressure value corresponding to the unit when it is running according to the preset target temperature, and multiple fan gears and corresponding multiple static pressure gears are preset, and the determined current static pressure does not exceed the static pressure value of the highest static pressure gear, and is not lower than the static pressure value of the lowest static pressure gear.

[0045] Static pressure is equivalent to a resistance phenomenon in the fan unit, which will generate a certain amount of reactive power. When the outlet water temperature remains unchanged and the gear is reduced by one gear, but the outlet temperature is measured to have dropped, this is equivalent to the water temperature remaining unchanged, the wind speed is reduced, and the outlet temperature has dropped instead, that is, the static pressure resistance has decreased, and the static pressure needs to be reduced by one static pressure gear on the current basis. Based on this, the current static pressure of the unit can be accurately identified according to the changes in the outlet temperature and the changes in the fan gear, so that more accurate power consumption data can be obtained.

[0046] After obtaining a relatively accurate static pressure value of the unit, the power consumption of the unit can be directly calculated according to the fan gear and the current static pressure ratio. Specifically, the corresponding power is determined according to the fan gear and the current static pressure; among them, the corresponding relationship between different fan gears, different static pressure gears and power is preset, such as Figure 2 As shown; the power consumption is calculated by the following formula: Power consumption Q = P A *t; where P Ais the power, and t is the running time of the unit. This embodiment performs factory tests on static pressure, gear position, and power, and calculates a more accurate power consumption of the fan by detecting the inlet and outlet water temperature and the outlet temperature. The obtained static pressure value of the unit can be fed back to the thermostat, thereby realizing automatic intelligent and precise adjustment of the unit and improving the user experience of the air conditioner.

[0047] Example 2

[0048] Figure 3 This is a calculation flow chart of a thermostat capable of calculating the power consumption of a fan unit according to an embodiment of the present invention. The specific implementation process is as follows:

[0049] For AC motors, power is determined by speed and static pressure. The speed is controlled by the gear position. The greater the static pressure, the greater the power per unit time.

[0050] Step S301: Before leaving the factory, the fan unit is running stably. When the indoor temperature reaches the target temperature T 目标 ℃, detect the inlet water temperature T 进水 ℃, water outlet temperature T 出水 ℃, air inlet temperature T 进风 ℃, outlet temperature T 出风 ℃, fan speed is N 目标温度 (indicates the fan speed corresponding to when the indoor temperature of the unit reaches the target temperature), and measures the static pressure of the current unit as Apa and the power P A The fan speed can be set to multiple gears. When the fan speed is adjusted to different gears, the corresponding unit static pressure and power are measured, and the above data are saved in the storage chip as factory data. Figure 2 .

[0051] When the unit is turned on, the inlet and outlet water temperatures are set to the factory values, and the fan gear is automatically adjusted. Since the fan gear is automatically adjusted according to the target temperature, when the water volume is constant, if the target temperature is x℃ higher, the gear wind speed will be increased by one level, and vice versa if the temperature is low. The IC chip can control the gear up and down and record it.

[0052] Step S302: The unit is in cooling operation. When the indoor temperature reaches the preset target temperature T 目标 Finally, determine whether the water outlet temperature and air outlet temperature have changed.

[0053] When the unit is turned on, the inlet and outlet water temperatures are set to the factory values. During the refrigeration operation of the unit, after the indoor temperature reaches the preset target temperature, it is determined whether the outlet water temperature has changed. Specifically, the outlet water temperature is compared with the factory value, for example, whether the difference between the two is less than the preset interval. If so, it is determined that the outlet water temperature has not changed. Otherwise, it is determined that the outlet water temperature has changed.

[0054] Determine whether the outlet temperature has changed, then when the indoor temperature reaches the preset target temperature T 目标 After that, you can directly monitor.

[0055] Step S303: If the water outlet temperature and the air outlet temperature do not change and are not much different from the factory values ​​(for example, the temperature difference is within the preset range), it is considered that the static pressure of the current unit is Apa and the power is P. A W, then the power consumption can be calculated as Q = P A *t(running time), P A is the power, and t is the operating time of the unit.

[0056] Step S304: If the outlet water temperature rises, the wind speed needs to be increased and the air volume needs to be increased to ensure that the overall temperature is reduced. At this time, it is necessary to confirm the number of gears that the fan gear is increased, and determine the current static pressure according to the increased number of gears.

[0057] 1) When the fan gear is raised by one gear, the current static pressure is determined to be the preset static pressure value Apa and the power is determined to be P A W;

[0058] 2) If the fan gear is increased by 2 or more gears, the static pressure is considered to be the preset static pressure value Apa. If the static pressure is reduced by 2 or more static pressure gears, Figure 2 The fan gear, static pressure gear, and the power corresponding to the two are shown in the figure. At this time, the static pressure has been determined, and the chip is based on Figure 2 The written data is paired with the gear and power to obtain the power at that time, and then multiplied by the running time t to display the power consumption.

[0059] Under the condition of keeping the target temperature unchanged, the greater the static pressure, the greater the wind speed and the greater the power. When the outlet water temperature rises (for example, from 5°C to 8°C), the temperature of the wind blown out by the unit will rise accordingly. At this time, the room temperature will exceed the target temperature. The fan gear is automatically adjusted according to the target temperature, and the fan gear is automatically increased by one gear to reduce the room temperature to the same as the target temperature. That is, when the outlet water temperature rises, the fan gear is increased to solve the problem. The effects of the two offset each other, making the room temperature consistent with the target temperature.

[0060] If the outlet water temperature decreases, it is necessary to confirm the number of gears that the fan has been reduced to, and determine the current static pressure based on the number of gears that have been reduced.

[0061] 1) When the fan gear is lowered by one gear, the current static pressure is determined to be the preset static pressure value Apa and the power is determined to be P A W;

[0062] 2) If the fan gear is reduced by 2 or more gears, the static pressure is considered to be the preset static pressure value Apa. If the static pressure is increased by 2 or more static pressure gears, Figure 2The fan gear, static pressure gear, and the power corresponding to the two are shown in the figure. At this time, the static pressure has been determined, and the chip is based on Figure 2 The written data is paired with the gear and power to obtain the power at that time, and then multiplied by the running time t to display the power consumption.

[0063] Step S305: When the outlet water temperature remains unchanged, if the fan gear is lowered and the outlet temperature drops, it means that the static pressure is reduced by one static pressure gear; if the fan gear is increased and the outlet temperature rises, it means that the static pressure needs to be increased by one static pressure gear. Figure 2 The written data is paired with the gear and power to obtain the power at that time, and then multiplied by the running time t to display the power consumption.

[0064] Static pressure is equivalent to a resistance phenomenon in the fan unit, which will generate a certain amount of reactive power. When the outlet water temperature remains unchanged and the gear is also reduced by one gear, but the outlet temperature is measured to have dropped, this is equivalent to the water temperature remaining unchanged, the wind speed is reduced, and the outlet temperature drops instead, that is, the static pressure resistance has become smaller. At this time, the static pressure and gear information have been obtained, and the power consumption can be obtained based on data matching.
