[0040] Some embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

The singular terms "one" and "the" may also include plural forms.

[0042] Normally, when the outlet water temperature of the hot water air conditioner is higher than the user-set temperature, the control system controls the unit to shut down. At this time, the water temperature begins to drop. When the outlet water temperature is lower than the user-set temperature, the control system controls the unit to start again. This cycle can easily lead to large water temperature fluctuations, frequent start and stop of the unit, and other problems, resulting in poor water outlet effect of the hot water air conditioner, high energy consumption, and short service life of the unit.

[0043] Therefore, in order to solve the above technical problems, the present invention provides the following technical solutions:

[0044] See attached Figure 1 , Figure 1FIG. 1 is a flow chart showing the main steps of a method for controlling a hot water air conditioner according to an embodiment of the present invention. Figure 1 As shown, the control method of the hot water air conditioner in the embodiment of the present invention mainly includes the following steps 101 to 103.

[0045] Step 101: during the hot water air conditioner heating operation, obtaining the outlet water temperature of the hot water air conditioner;

[0046] In a specific implementation process, when the hot water air conditioner is in heating operation, the outlet water temperature of the hot water air conditioner can be obtained in real time through a sensor.

[0047] Step 102, detecting whether the outlet water temperature of the hot water air conditioner is greater than the user set temperature;

[0048] After the outlet water temperature of the hot water air conditioner is obtained, the outlet water temperature of the hot water air conditioner may be compared with the user set temperature to detect whether the outlet water temperature of the hot water air conditioner is greater than the user set temperature.

[0049] It should be noted that the user-set temperature can be set manually by the user, or it can be automatically set according to the user's personal habits after obtaining the user's identity information using a camera, voice recognition technology, etc. This embodiment does not make any specific restrictions.

[0050] Step 103: If the outlet water temperature of the hot water air conditioner is greater than the user set temperature, gradually reduce the operating load of the unit according to a preset load reduction amount until the outlet water temperature is less than or equal to the user set temperature.

[0051] In a specific implementation process, if the outlet water temperature of the hot water air conditioner is greater than the user-set temperature, it means that the user's usage requirements have been met. However, if the unit is directly controlled to shut down at this time, the outlet water temperature may drop rapidly, and the user's usage requirements cannot be met for a long time. After the outlet water temperature drops rapidly, the unit will be started again to heat the water again. This will easily cause energy waste, and frequent starting of the unit will shorten the service life of the unit. Therefore, a load reduction amount can be set in advance, and the operating load of the unit can be gradually reduced according to the preset load reduction amount until the outlet water temperature is less than or equal to the user-set temperature, so as to avoid frequent starting of the unit and reduce the water temperature without large fluctuations.

[0052] The process of obtaining the operating load of the unit includes:

[0053] According to the following load calculation formula, the operating load of the unit is obtained:

[0054] P=C*60*Q*(T WO -T WI ) / 1000 / 3600

[0055] Among them, P represents the load of the unit, C represents the specific heat capacity of water, Q represents the water flow rate detected by the flow meter, and T WO Indicates the outlet water temperature, T WI Indicates the inlet water temperature.

[0056] The control method of the hot water air conditioner of this embodiment, during the heating operation of the hot water air conditioner, if it is detected that the outlet water temperature of the hot water air conditioner is greater than the user-set temperature, the operating load of the unit can be gradually reduced according to the preset load reduction amount until the outlet water temperature is less than or equal to the user-set temperature. In this way, when the outlet water temperature of the hot water air conditioner is greater than the user-set temperature, the unit will not shut down, but will gradually reduce the operating load, ensuring that the outlet water temperature will not fluctuate greatly, meeting the user's use needs, improving the water outlet effect, and when heating the water again, it will not be heated under low water temperature conditions, reducing the energy consumption of the hot water air conditioner, avoiding frequent startup of the unit, and extending the service life of the unit.

[0057] In a specific implementation process, the hot water air conditioner may be provided with an auxiliary heat source such as electric heating. Thus, before "gradually reducing the operating load of the unit according to a preset load reduction amount" in step 103, it is also possible to detect whether the auxiliary heat source is in an on state; if the auxiliary heat source is in an on state, the auxiliary heat source is turned off, and the operating load of the hot water air conditioner unit is maintained. In other words, if the auxiliary heat source is in an on state, the auxiliary heat source is no longer used for heating, and the operating load of the hot water air conditioner unit is maintained.

[0058] Correspondingly, if the auxiliary heat source is not in the on state, then the step 103 of "gradually reducing the operating load of the unit according to a preset load reduction amount" is executed.

[0059] In a specific implementation process, the process of setting the load reduction amount may include the following methods:

[0060] The first method is to set the load reduction amount in response to a load reduction setting request. That is, the user can set a load reduction amount according to actual needs, such as a preset percentage.

[0061] The second method is to obtain the temperature difference between the outlet water temperature and the user set temperature, and set the load reduction amount according to the temperature difference. In other words, the hot water air conditioner can automatically set the load reduction amount.

[0062] Specifically, when the temperature difference between the outlet water temperature and the user set temperature is greater than the preset temperature difference, a larger load reduction amount can be set. When the temperature difference between the outlet water temperature and the user set temperature is less than or equal to the preset temperature difference, a smaller load reduction amount can be set.

[0063] It should be noted that the load reduction amount can be a specific value, and the operating load is reduced by a fixed value each time it is reduced, or it can be a curve formed by multiple values, and the operating load is reduced by different values ​​each time it is reduced.

[0064] In a specific implementation process, after "gradually reducing the operating load of the unit according to a preset load reduction amount" in step 103, the following steps may also be performed:

[0065] (1) After the unit has been running for a set time at the reduced operating load, obtaining the rate of change of the outlet water temperature;

[0066] After the unit's reduced operating load is obtained during the current load reduction, the unit can operate for a set time at the reduced operating load. At this time, the rate of change of the outlet water temperature can be obtained based on the outlet water temperature of the unit before the reduced operating load and the outlet water temperature of the unit after the reduced operating load.

[0067] (2) If the change rate is less than a preset change rate, the load reduction amount is increased so that the operating load of the unit is reduced according to the increased load reduction amount next time.

[0068] In a specific implementation process, if the change rate is less than the preset change rate, it means that the set load reduction amount may be small, so that the outlet water temperature cannot be quickly reduced to the user-set temperature or reduced to below the user-set temperature. At this time, the load reduction amount can be increased so that the operating load of the unit can be reduced according to the increased load reduction amount next time. In this way, the load reduction amount can be dynamically adjusted to quickly achieve the purpose of cooling and energy saving.

[0069] See attached Figure 2 , Figure 2 FIG. 1 is a flow chart showing the main steps of a method for controlling a hot water air conditioner according to another embodiment of the present invention. Figure 2 As shown, the control method of the hot water air conditioner in the embodiment of the present invention mainly includes the following steps 201 to 207.

[0070] Step 201: If the running time of the unit reaches a preset time and the running load of the unit does not change within the preset time, detect whether the running load of the unit is greater than the preset running load; if so, execute step 202; if not, execute step 203;

[0071] In a specific implementation process, during the hot water air conditioning heating operation, it is possible to detect in real time whether the unit's operating time has reached a preset time, and detect whether the unit's operating load has not changed within the preset time. If the unit's operating time has reached a preset time, and the unit's operating load has not changed within the preset time, detect whether the unit's operating load is greater than the preset operating load. If the unit's operating time has not reached the preset time, re-detect whether the unit's operating time has reached the preset time, or if the unit's operating load has changed within the preset time, the unit's operating time is reset to zero, and re-detect whether the unit's operating time has reached the preset time.

[0072] Step 202: Control the operating load of the unit to be reduced to the preset operating load, or control the operating load of the unit to be reduced to below the preset operating load;

[0073] If the operating load of the unit is greater than the preset operating load, it means that the heating capacity of the unit exceeds the nominal capacity of the unit. At this time, the operating load of the unit can be controlled to be reduced to the preset operating load, or the operating load of the unit can be controlled to be reduced below the preset operating load.

[0074] Step 203, obtaining the outlet water temperature of the hot water air conditioner, and detecting whether the outlet water temperature of the hot water air conditioner is greater than the user set temperature; if so, executing step 204, if not, executing step 207;

[0075] If the operating load of the unit is less than or equal to the preset operating load, the outlet water temperature of the hot water air conditioner can be obtained, and it can be detected whether the outlet water temperature of the hot water air conditioner is greater than the user-set temperature.

[0076] Step 204, detecting whether the auxiliary heat source is turned on; if so, executing step 205; if not, executing step 206;

[0077] Step 205: turning off the auxiliary heat source and maintaining the operating load of the hot water air conditioner unit;

[0078] Step 206: gradually reduce the operating load of the unit according to a preset load reduction amount until the outlet water temperature is less than or equal to the user-set temperature.

[0079] Step 207: Maintain the operating load of the hot water air conditioning unit.

[0080] If the outlet water temperature of the hot water air conditioner is less than or equal to the user set temperature, the operating load of the hot water air conditioner unit is maintained.

[0081] It should be noted that although the above embodiments describe the various steps in a specific order, those skilled in the art can understand that, in order to achieve the effects of the present invention, it is not necessary to execute the different steps in such an order. They can be executed simultaneously (in parallel) or in other orders, and these variations are all within the protection scope of the present invention.

[0082] In a specific implementation process, the working process of the hot water air conditioner is as described below:

[0083] During the heating operation of the hot water air conditioner, when the operating time of the unit reaches t1 and the load of the unit does not change during t1 (when the load of the unit changes, the t1 time is cleared), at this time, the relationship between the operating load P of the unit and the preset operating load P0 is detected. When P > P0, the operating load of the unit is reduced, and the goal is to reduce it to P0; when P ≤ P0, the outlet water temperature T of the hot water air conditioner is detected. WO The relationship with the user-set temperature T, when T WO ≥ T, it is detected whether the electric heating is turned on. If the electric heating is turned on, the electric heating is directly turned off and the unit continues to operate according to the operating load at the current time; if the electric heating is not turned on, it continues to operate according to the operating load * a. When TWO < T, the unit does not make any changes and continues to operate according to the operating load of the unit at the current time.
