There are multiple preset fan speeds and corresponding static pressure speeds. The current static pressure is determined to be no more than the static pressure value of the highest static pressure speed and no less than the static pressure value of the lowest static pressure speed.

[0029] The optional embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Example 1

[0030] According to an embodiment of the present invention, an embodiment of a method for determining unit power consumption is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0031] Figure 1 This is a flowchart of a method for determining unit power consumption according to an embodiment of the present invention, such as... Figure 1 As shown, the method includes the following steps:

[0032] Step S101: When the unit is running in cooling mode, after the indoor temperature reaches the preset target temperature, the water outlet temperature and air outlet temperature of the unit are detected.

[0033] Step S102: If the outlet water temperature changes, determine the current static pressure based on the outlet water temperature change trend and the fan speed; if the outlet air temperature changes while the outlet water temperature remains unchanged, determine the current static pressure based on the outlet air temperature change trend and the fan speed.

[0034] Step S103: Based on the fan speed and the current power consumption of the static pressure computer unit.

[0035] This embodiment combines the unit's outlet water temperature, outlet air temperature, and fan speed to determine the unit's current static pressure. Then, it combines the factory settings to determine the power corresponding to the static pressure and fan speed. Based on this, accurate power consumption data of the fan coil unit is calculated. Users can also query the power consumption data in real time. The thermostat can then achieve more effective and accurate automatic intelligent adjustment of the unit, improving the user experience of the air conditioner.

[0036] In this embodiment, the outlet water temperature is the temperature of the unit's outlet water pipe. The outlet water pipe and 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, thus lowering the water temperature. The outlet water pipe is connected to the indoor unit, and the air blown out by the fan passes through the outlet water pipe, thereby lowering the temperature of the outlet air.

[0037] In this embodiment, the fan coil unit operates stably before leaving the factory, and the indoor temperature reaches the preset target temperature T. 目标 When the inlet water temperature T is measured at ℃ (e.g., 26℃), the temperature is measured. 进水 ℃ (e.g., 5℃), outlet water temperature T 出水 ℃ (e.g., 7℃), inlet air temperature T 进风 ℃ (e.g., 28℃), outlet air temperature T 出风 ℃ (e.g., 26℃), fan speed is N 目标温度 The static pressure was measured to be Apa and the power P. A (The gear position is now determined), the data is stored on the memory chip, and it is the factory data, such as... Figure 2 The diagram shows the factory data of the unit. That is, the factory data contains multiple fan speed settings and corresponding static pressure settings, as well as the correspondence between these two and the power. For example, when the fan speed setting is two and the static pressure is 12pa, the corresponding power under this operating condition is P8.

[0038] When the unit is started, the inlet and outlet water temperatures are set to the factory values. During the cooling 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 range. If so, it is determined that the outlet water temperature has not changed; otherwise, it is determined that the outlet water temperature has changed.

[0039] In this embodiment, when a change in outlet water temperature is detected, the current static pressure is determined based on the outlet water temperature change trend and the fan speed setting. Specifically, if the outlet water temperature changes, the number of fan speed settings that change is confirmed; the current static pressure is then determined based on the outlet water temperature change trend and the number of fan speed settings that change. When the unit's outlet water temperature changes, the fan speed setting will change accordingly, and the degree of change in fan speed setting reflects the current static pressure situation. Therefore, this embodiment determines the current static pressure based on the outlet water temperature change trend and the number of fan speed settings that change, thereby enabling a more accurate determination of the unit's current static pressure value.

[0040] While maintaining the preset target temperature, the higher the static pressure, the greater the required air velocity and the greater the power. As the outlet water temperature increases (from 5℃ to 8℃), the temperature of the blown air also increases. At this point, the room temperature is higher than the preset target temperature. The fan speed is automatically adjusted according to the preset target temperature, increasing one speed to bring the room temperature closer to the target temperature.

[0041] If the outlet water temperature trend is upward, determine the number of fan speed increases and then determine the current static pressure based on that number of speed increases. Specifically, if the increase is one speed, the current static pressure is determined to be the preset static pressure value; where the preset static pressure value is the static pressure value corresponding to the unit operating at a preset target temperature. If the increase is n speeds, the current static pressure is determined to be the static pressure value after reducing the preset static pressure value by n static pressure speeds; where n is a positive integer, there are multiple preset fan speeds and corresponding multiple static pressure speeds, and the determined current static pressure is not lower than the static pressure value of the lowest static pressure speed. Based on this, the current static pressure status of the unit can be accurately identified according to changes in outlet water temperature and fan speed, thus obtaining more accurate power consumption data.

[0042] If the outlet water temperature is trending downwards, determine the number of fan speed reductions and then the current static pressure based on those reductions. Specifically, if the reduction is one speed, the current static pressure is the preset static pressure value; this preset static pressure value is the static pressure value corresponding to the unit operating at a preset target temperature. If the reduction is n speeds, the current static pressure is the static pressure value after increasing the preset static pressure value by n speeds; where n is a positive integer, there are multiple preset fan speeds and corresponding static pressure levels, and the determined current static pressure does not exceed the static pressure value of the highest static pressure level. Based on this, the current static pressure status of the unit can be accurately identified according to changes in outlet water temperature and fan speed, thus obtaining more accurate power consumption data.

[0043] If the unit's outlet water temperature remains constant, a decrease in fan speed will result in a decrease in outlet air temperature, while an increase in fan speed will result in an increase in outlet air temperature. Specifically, in this embodiment, if the outlet air temperature changes while the outlet water temperature remains constant, the current static pressure is determined based on the outlet air temperature change trend and the fan speed. Specifically, if the outlet air temperature decreases and the fan speed decreases, the current static pressure is determined to be the static pressure value after increasing the preset static pressure value by one static pressure level; if the outlet air temperature increases and the fan speed increases, the current static pressure is determined to be the static pressure value after decreasing the preset static pressure value by one static pressure level. The preset static pressure value is the static pressure value corresponding to the unit operating at a preset target temperature. Multiple fan speeds and corresponding static pressure levels are preset, and the determined current static pressure does not exceed the static pressure value of the highest static pressure level and is not lower than the static pressure value of the lowest static pressure level.

[0044] Static pressure in a fan coil unit is equivalent to a resistance phenomenon, generating a certain amount of reactive power. When the outlet water temperature remains constant and the fan speed is reduced by one level, but the measured temperature at the outlet air decreases, this is equivalent to the water temperature remaining constant, the fan speed decreasing, yet the outlet air temperature decreasing. This indicates that the static pressure resistance has decreased, and the static pressure needs to be reduced by one level from the current level. Based on this, the current static pressure status of the unit can be accurately identified by changes in outlet air temperature and fan speed, thus obtaining more accurate power consumption data.

[0045] After obtaining a relatively accurate static pressure value for the unit, the power consumption of the unit can be directly calculated based on the fan speed and the current static pressure ratio. Specifically, the corresponding power is determined based on the fan speed and the current static pressure; there are preset correspondences between different fan speeds, different static pressure levels, and power, such as... Figure 2 As shown; power consumption is calculated using the following formula: Power consumption Q = P A *t; where P AHere, 't' represents power, and 't' represents the unit's operating time. This embodiment performs factory tests on static pressure, speed setting, and power, and calculates a relatively accurate power consumption of the fan by detecting inlet and outlet water temperatures and air outlet temperatures. Furthermore, the obtained static pressure value of the unit can be fed back to the thermostat, thereby achieving automatic, intelligent, and precise adjustment of the unit and improving the user experience of the air conditioner. Example 2

[0046] Figure 3 This is a flowchart illustrating the calculation process of a temperature controller capable of calculating the power consumption of a fan coil unit according to an embodiment of the present invention. The specific implementation process is as follows:

[0047] For AC motors, power is determined by speed and static pressure. Speed ​​is controlled by gear, and the higher the static pressure, the greater the power per unit time.

[0048] Step S301: Before leaving the factory, the fan coil unit operates stably until the indoor temperature reaches the target temperature T. 目标 At ℃, the inlet water temperature T is measured. 进水 ℃, outlet water temperature T 出水 ℃, inlet air temperature T 进风 ℃, outlet temperature T 出风 ℃, fan speed is N 目标温度 (This indicates the fan speed at which the indoor temperature of the unit reaches the target temperature), measure the current static pressure of the unit as Apa and the power as P. A Multiple fan speed settings can be configured. When the fan speed is adjusted to different settings, the corresponding static pressure and power of the unit are measured and saved on a storage chip as factory default data. Figure 2 .

[0049] When the unit is started, the inlet and outlet water temperatures are set to factory defaults, and the fan speed is automatically adjusted. Since the fan speed is automatically adjusted based on the target temperature, with a fixed water volume, if the target temperature is x℃ higher, the fan speed will increase by one level, and vice versa if the temperature is lower. The IC chip controls the raising and lowering of the fan speed and records the settings.

[0050] Step S302: The unit operates in cooling mode until the indoor temperature reaches the preset target temperature T. 目标 Then, determine whether there are any changes in the water outlet temperature and the air outlet temperature.

[0051] When the unit is started, the inlet and outlet water temperatures are set to the factory values. During the cooling 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 range. If so, it is determined that the outlet water temperature has not changed; otherwise, it is determined that the outlet water temperature has changed.

[0052] To determine if the air outlet temperature has changed, wait until the indoor temperature reaches the preset target temperature T. 目标 After that, monitoring can be carried out directly.

[0053] Step S303: If the outlet water temperature and outlet air temperature remain unchanged and are not significantly different from the factory settings (e.g., the temperature difference is within the preset range), then the static pressure of the current unit is considered to be Apa and the power is P. A W, at this point, the power consumption Q=P can be calculated. A *t (running time), P A t is the power, and t is the unit's operating time.

[0054] In step S304, if the outlet water temperature rises, the fan speed needs to be increased to increase the air volume and ensure that the overall temperature decreases. At this time, it is necessary to confirm the number of speed settings increased by the fan and determine the current static pressure based on the number of speed settings increased.

[0055] 1) If the fan speed is increased by one level, the current static pressure is confirmed to be the preset static pressure value (Apa), and the power is confirmed to be (P). A W;

[0056] 2) If the fan speed is increased by two or more levels, the static pressure is considered to be at the preset static pressure value (Apa). If the static pressure is decreased by two or more levels, the static pressure is considered to be at the preset static pressure value (Apa). Figure 2 The display shows the fan speed setting, static pressure setting, and their corresponding power. At this point, the static pressure is determined, and the chip... Figure 2 The written data is matched with the power level to obtain the current power, and then multiplied by the running time t to display the power consumption.

[0057] While maintaining the target temperature, higher static pressure requires higher airflow and thus higher power. When the outlet water temperature increases (e.g., from 5°C to 8°C), the temperature of the air blown out by the unit also increases. At this point, the room temperature will exceed the target temperature. The fan speed, which is automatically adjusted according to the target temperature, will automatically increase by one level to lower the room temperature to match the target temperature. In other words, the increase in fan speed is used to address the issue of rising outlet water temperature; the effects of both cancel each other out, ensuring that the room temperature matches the target temperature.

[0058] If the outlet water temperature decreases, it is necessary to confirm the number of speeds the blower has been reduced by, and determine the current static pressure based on the number of speeds reduced.

[0059] 1) If the fan speed is lowered by one level, the current static pressure is determined to be the preset static pressure value (Apa), and the power is determined to be (P). A W;

[0060] 2) If the fan speed is reduced by two or more levels, the static pressure is considered to be at the preset static pressure value (Apa). If the static pressure is increased by two or more levels, the static pressure is considered to be at the preset static pressure value (Apa). Figure 2The display shows the fan speed setting, static pressure setting, and their corresponding power. At this point, the static pressure is determined, and the chip... Figure 2 The written data is matched with the power level to obtain the current power, and then multiplied by the running time t to display the power consumption.

[0061] In step S305, if the outlet temperature decreases when the fan speed is lowered, it indicates that the static pressure has decreased by one level; if the outlet temperature increases when the fan speed is higher, it indicates that the static pressure needs to be increased by one level. At this point, the static pressure is determined, and the chip... Figure 2 The written data is matched with the power level to obtain the current power, and then multiplied by the running time t to display the power consumption.

[0062] Static pressure in a fan coil unit is equivalent to a resistance phenomenon, which generates a certain amount of reactive power. When the outlet water temperature remains constant and the speed is reduced by one level, but the measured temperature at the air outlet decreases, this situation is equivalent to the water temperature remaining constant, the air velocity decreasing, and the outlet temperature actually decreasing. This means that the static pressure resistance has decreased. At this point, the static pressure and speed information have been obtained, and the power consumption can be calculated based on the data matching. Example 3
