Description

Technical Field

[0001] This invention relates to the field of air source heat pump water heater technology, and more specifically, to a control method, device, and air conditioner for floor drying in an air source heat pump water heater. Background Technology

[0002] With the increasing popularity of air source heat pump water heaters, most families use them as their main heating system (air conditioning, underfloor heating). However, due to improper use of underfloor heating, the number of floor coverings warping has been increasing year by year, causing considerable inconvenience to users.

[0003] The reason is that when the underfloor heating is not in use, the flooring materials (especially solid wood flooring and composite flooring) will absorb a certain amount of moisture, and the rapid heating will cause the flooring materials to deform and warp. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a control method for floor drying in an air-source heat pump water heater. The method includes a temperature gradual increase process as follows: acquiring the current water temperature and the target water temperature for each heating cycle; controlling the water temperature increase based on the target water temperature of the current heating cycle; periodically detecting the current water temperature; if the current water temperature reaches the target water temperature of the current heating cycle, determining whether correction is needed based on the current ambient humidity and the saturated ambient humidity corresponding to the current ambient temperature; if correction is needed, lowering the target water temperature of the current heating cycle to the corrected water temperature, and continuously running the current heating cycle for the corresponding duration at the corrected water temperature; if no correction is needed, continuously running the current heating cycle for the corresponding duration at the target water temperature of the current heating cycle; controlling the water temperature increase based on the target water temperature of the next heating cycle; the target water temperature of the next heating cycle is greater than the target water temperature of the current heating cycle; returning to the above target temperature correction judgment step, until the heating process of the last heating cycle is completed.

[0005] The control method for drying floors in an air-source heat pump water heater provided in this invention can set the target water temperature for each heating cycle and control the temperature rise slowly based on the target water temperature for each heating cycle. In addition, a correction process based on the current ambient humidity and saturated ambient humidity is added during the control process, thereby removing excess moisture and humidity from the floor and reducing the warping of flooring materials caused by direct heating.

[0006] Optionally, the method further includes a temperature reduction process as follows: if the current water temperature reaches the highest target drying temperature, and the heating cycle corresponding to the highest target drying temperature is continuously run at the highest target drying temperature for the specified duration, then the target water temperature for each cooling cycle is obtained; the water temperature is controlled to decrease based on the target water temperature of the first cooling cycle; if the current water temperature reaches the target water temperature of the first cooling cycle, the water temperature is continuously run at the target water temperature of the first cooling cycle for the specified duration; the water temperature is controlled to decrease based on the target water temperature of the next cooling cycle; and if the current water temperature reaches the target water temperature of the next cooling cycle, the water temperature is continuously run at the target water temperature of the next cooling cycle for the specified duration; the target water temperature of the next cooling cycle is lower than the target water temperature of the current cooling cycle.

[0007] The embodiments of the present invention further incorporate a temperature slow-down process, thereby further improving the removal of moisture and humidity from the floor.

[0008] Optionally, determining whether correction is needed based on the current ambient humidity and the saturated ambient humidity corresponding to the current ambient temperature includes: calculating the humidity difference between the current ambient humidity and the saturated ambient humidity corresponding to the current ambient temperature; if the humidity difference is greater than a preset humidity difference threshold, it is determined that no correction is needed; if the humidity difference is less than or equal to the preset humidity difference threshold, it is determined that correction is needed.

[0009] In this embodiment of the invention, the need for correction is determined by the current ambient humidity and the saturated ambient humidity corresponding to the current ambient temperature. By combining the ambient temperature and humidity conditions, the drying efficiency of the floor can be improved.

[0050] Figure 5A schematic diagram of the structure of a control device for floor drying of an air source heat pump water heater according to an embodiment of the present invention is shown. Detailed Implementation

[0051] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0052] This invention provides a floor drying (floor preheating) function for an air source heat pump water heater. When the underfloor heating function is used for the first time in the year, the excess water vapor and moisture on the floor are removed by using a temperature slow rise control strategy, reducing the risk of flooring materials warping due to strong heating.

[0053] Figure 1 A schematic flowchart of a control method for floor drying using an air-source heat pump water heater according to an embodiment of the present invention is shown. The method includes a gradual temperature rise process as follows:

[0054] S102, obtain the current water temperature and the target water temperature for each heating cycle.

[0055] The duration of each heating cycle can be equal or unequal. During implementation, a target water temperature can be set for each heating cycle, with the overall trend of the target water temperature increasing to achieve a gradual rise in underfloor heating temperature. Optionally, the target water temperature for each heating cycle can be determined by the current water temperature and the highest drying temperature during the heating process. The number of heating cycles and the target water temperature for each cycle can be customized by the user, improving ease of use.

[0056] S104 controls the water temperature rise based on the target water temperature of the current heating cycle.

[0057] Air source heat pump water heaters use the target water temperature of the current heating cycle as the target temperature and activate the heating function to control the water temperature rise.

[0058] S106: Periodically detect the current water temperature. If the current water temperature reaches the target water temperature of the current heating cycle, determine whether correction is needed based on the current ambient humidity and the saturated ambient humidity corresponding to the current ambient temperature.

[0059] During the water temperature rise process, the current water temperature can be monitored periodically to determine if it has reached the target temperature for the current heating cycle. If it has, the current ambient humidity and the corresponding saturation humidity at the current ambient temperature can be used to determine if adjustments are needed. If the current ambient humidity is close to the saturation temperature, it indicates that the floor is drying too quickly (i.e., the target water temperature for the current heating cycle is too high), causing a significant increase in humidity to near the saturation temperature. Conversely, if the current ambient humidity is far from the saturation temperature, it indicates that the floor is drying at a suitable rate.

[0060] For example, the determination of whether a correction is needed is made in the following manner:

[0061] The system calculates the humidity difference between the current ambient humidity and the saturated ambient humidity corresponding to the current ambient temperature. If the humidity difference is greater than a preset humidity difference threshold, it is determined that no correction is needed; if the humidity difference is less than or equal to the preset humidity difference threshold, it is determined that correction is needed. This preset humidity difference threshold can be adaptively determined based on factors such as the current indoor ambient humidity and indoor temperature, and this embodiment does not impose any restrictions on it. By combining ambient temperature and humidity conditions, the floor drying efficiency can be improved.

[0062] S108, if correction is required, the target water temperature of the current heating cycle will be lowered to the corrected water temperature, and the current heating cycle will continue to run for the corresponding duration at the corrected water temperature.

[0063] Considering the possibility that the target water temperature for the current heating cycle may be set too high, if the above-mentioned situation requiring correction is detected, the target water temperature for the current heating cycle will be appropriately reduced, and then the operation of the water heater will be controlled with the reduced water temperature to avoid the floor heating up too quickly.

[0064] S110, if no correction is needed, the current heating cycle will continue to run for the corresponding duration at the target water temperature of the current heating cycle.

[0065] S112, the target water temperature of the next heating cycle is used as the target to control the water temperature rise; the target water temperature of the next heating cycle is greater than the target water temperature of the current heating cycle.

[0066] S114, return to the above target temperature correction judgment step, until the final heating cycle is completed.

[0067] After executing S112, return to execute S106, thereby repeatedly executing the above steps of target temperature correction and judgment, as well as the steps of controlling the water temperature rise with the target water temperature of the next heating cycle, until the heating process of the last heating cycle is completed.

[0068] The control method for drying floors in an air-source heat pump water heater provided in this invention can set the target water temperature for each heating cycle and control the temperature rise slowly based on the target water temperature for each heating cycle. In addition, a correction process based on the current ambient humidity and saturated ambient humidity is added during the control process, thereby removing excess moisture and humidity from the floor and reducing the warping of flooring materials caused by direct heating.

[0069] Based on the aforementioned gradual temperature rise process, the heating cycle can achieve the floor drying function and also serve as a preheating function before normal heating begins. Considering that the floor drying function can be scheduled in advance without further heating, a gradual temperature drop process can be added to further improve the removal of moisture and humidity from the floor. Therefore, the above method also includes:

[0070] First, if the current water temperature reaches the maximum target drying temperature, and the system continues to operate at the maximum target drying temperature for the corresponding duration of the heating cycle, then the target water temperature for each cooling cycle is obtained.

[0071] Secondly, the water temperature is controlled to decrease based on the target water temperature of the first cooling cycle.

[0072] Then, if the current water temperature reaches the target water temperature of the first cooling cycle, the system will continue to run at the target water temperature of the first cooling cycle for the corresponding duration of the first cooling cycle.

[0073] Finally, the target water temperature for the next cooling cycle is used as the target to control the water temperature decrease. If the current water temperature reaches the target water temperature for the next cooling cycle, the water temperature will continue to run for the corresponding duration of the next cooling cycle at the target water temperature for the next cooling cycle. The target water temperature for the next cooling cycle is lower than the target water temperature for the current cooling cycle.

[0074] Based on the above-mentioned temperature reduction process, a target water temperature can be set for each cooling cycle. By controlling the slow cooling with the target water temperature for each cooling cycle, excess moisture and humidity in the floor can be further removed, preventing the flooring material from warping.

[0075] Optionally, the slope of the heating cycle can be calculated based on the following formula:

[0076] K 1_UP =(T DRY_HI -T WO_T0 ) / t DRY_UP integer part

[0077] K 2_UP =(T DRY_HI -T WO_T0 ) / t DRY_UP decimal part

[0079] The target water temperature for each heating cycle is calculated based on the following formula:

[0081] T NOW_STEP_UP_T2 =2*K 1_UP +T WO_T0 +K 2_UP

[0085] Optionally, the slope of the cooling cycle can be calculated based on the following formula:

[0086] K 1_DOWN =(T DRY_DOWN -T DRY_HI ) / t DRY_DOWN integer part

[0087] K 2_DOWN =(T DRY_DOWN -T DRY_HI ) / t DRY_DOWN decimal part

[0088] Among them, K 1_DOWN K represents the integer part of the slope. 2_DOWN T is the decimal part of the slope. DRY_HI To achieve the highest target drying temperature, T DRY_DOWN The drying and cooling temperature, t DRY_DOWN The number of cooling cycles;

[0089] The target water temperature for each cooling cycle is calculated using the following formula:

[0090] T NOW_STEP_DOWN_T1 =1*K 1_DOWN +T DRY_HI +K 2_DOWN

[0091] T NOW_STEP_DOWN_T2 =2*K 1_DOWN +T DRY_HI +K 2_DOWN

[0092] ...

[0093] T NOW_STEP_DOWN_Tn =n*K 1_DOWN +T DRY_HI +K 2_DOWN

[0094] Among them, T NOW_STEP_DOWN_T1 The target water temperature for the first cooling cycle, T NOW_STEP_DOWN_T2 The target water temperature for the second cooling cycle, T NOW_STEP_DOWN_Tn The target water temperature for the nth cooling cycle.

[0095] Optionally, the corrected water temperature can be calculated based on the following formula:

[0096] T NOW_STEP_UP_T1_ADJ =T NOW_STEP_UP_T1 +T ADJ ;

[0097] Among them, T NOW_STEP_UP_T1 The target water temperature for the first heating cycle, T NOW_STEP_UP_T1_ADJ T is the corrected water temperature for the first heating cycle. ADJ To correct the temperature;

[0098] The corrected temperature is calculated based on the following formula:

[0099] T ADJ =-1*K 1_UP / 2.

[0100] This embodiment also provides a scheduled floor drying function or a user-controlled drying function, thereby ensuring that the floor drying is automatically activated once in advance for the first use of the year. Based on this, the above method further includes:

[0101] The system receives a user-inputted scheduled drying command and executes the aforementioned temperature gradual increase process according to the command; or, it executes the aforementioned temperature gradual increase process according to a pre-set scheduled time.

[0140] S219, Exit floor dryer and turn off.

[0141] The specific formula for correcting the floor drying temperature is as follows:

[0142] Under normal circumstances, the moisture content of solid wood flooring is 10% to 20%. After turning on the underfloor heating function, the moisture content of solid wood flooring is between 8% and 10%. Turning on the underfloor heating function has no effect on ceramic tile flooring.

[0143] Settings: Ambient temperature: T A Ambient humidity: H R Flooring material: solid wood, according to T A (Ambient temperature) Refer to the table to obtain H at the current temperature. S ;

[0144] When HR (Ambient humidity) - H S (Saturated humidity) Humidity difference ΔH is greater than ΔH MIN (Minimum target humidity difference before drying) will not be corrected for ambient humidity.

[0145] When H R (Ambient humidity) - H S (Saturated humidity) Humidity difference ΔH is less than ΔH MIN (Minimum target humidity difference before drying), current water temperature has reached T. NOW_STEP_UP_T1 (Target water temperature on day 1) indicates that the drying rate is too fast. At this point, T ADJ (Corrected temperature) = -1 * K 1_UP / 2;

[0146] If the next cycle also requires adjustment, then the current temperature adjustment is invalid, and so on.

[0147] This invention provides a floor drying function, which allows users to customize various parameters to improve ease of use. When the underfloor heating mode is turned on for the first time in a year, a gradual temperature rise / fall process is performed to expel excess moisture and humidity from the floor, reducing the risk of flooring materials warping due to direct heating.
