For example, a process, method, system, product, or equipment that includes a series of steps or units does not necessarily limit to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or equipment.

[0029] For ease of understanding, the specific process of the embodiment of the present invention is described below. Please refer to Figure 1 , the first embodiment of the water temperature adjustment method in the embodiment of the present invention includes:

[0030] 101. In response to a mode selection instruction for a heat pump, determining a target working mode corresponding to the mode selection instruction;

[0031] In this embodiment, the heat pump determines the target working mode pointed to by the mode selection instruction based on the acquired mode selection instruction in response.

[0032] Specifically, the heat pump includes the following working modes, and determines any of the following working modes as the target working mode through the mode selection instruction.

[0033] Specifically, the working modes include: refrigeration water outlet (automatic adjustment); heating water outlet (automatic adjustment); dehumidification water outlet (automatic adjustment); refrigeration water outlet (manual setting); heating water outlet (manual setting); dehumidification water outlet (manual setting).

[0034] Further, if the target working mode pointed to by the mode selection instruction is (manual setting), it is no longer limited to the water outlet temperature control rule.

[0035] 102. Identify whether the target operating mode is executed for the first time in the heat pump to obtain an identification result;

[0036] In this embodiment, by determining whether the target operating mode selected by the mode selection instruction is executed by the heat pump for the first time, the identification result is obtained.

[0037] Specifically, when the heat pump responds to the mode selection instruction, based on the mode selection instruction, determine the target operating mode executed by the heat pump, and record the execution times of the corresponding target operating mode when executing the target operating mode. Determine whether the execution times are greater than 1. If so, generate an identification result, and the identification result is that the target operating mode is not executed for the first time; if not, generate an identification result, and the identification result is that the target operating mode is executed for the first time.

[0038] 103. Determine the outlet water temperature control rule corresponding to the target operating mode based on the identification result;

[0039] In this embodiment, determine the outlet water temperature control rule corresponding to the target operating mode based on the identification result.

[0040] Specifically, through the determined identification result and the determined target operating mode, execute the corresponding outlet water temperature control rule.

[0041] Furthermore, in each operating mode, there are at least two sets of outlet water temperature control rules. By determining whether the heat pump executes the target operating mode for the first time, different outlet water temperature control rules are selected to adjust the water temperature.

[0042] 104. Control the heat pump to adjust the water temperature based on the outlet water temperature control rule.

[0043] In this embodiment, the outlet water temperature of the heat pump is adjusted by applying the corresponding outlet water temperature control rule.

[0044] Furthermore, when applying the corresponding outlet water temperature control rule, there are corresponding control parameters in the outlet water temperature control rule. The heat pump collects the control parameters specified in the water temperature control rule to determine the outlet water temperature.

[0045] Specifically, the control parameters are collected through sensors loaded on the heat pump. The control parameters can be the outdoor temperature, the air supply temperature, or the dew point temperature.

[0046] In an embodiment of the present invention, in response to a mode selection instruction for a heat pump, a target operating mode corresponding to the mode selection instruction is determined; it is identified whether the target operating mode is executed for the first time in the heat pump to obtain an identification result; a water outlet temperature control rule corresponding to the target operating mode is determined based on the identification result; and the heat pump is controlled to adjust the water temperature based on the water outlet temperature control rule. By initially responding to the corresponding mode selection instruction, selecting the corresponding water outlet temperature control rule based on the determined target operating mode, the present application provides an automatic adjustment method for the water temperature under different target operating modes, further improving the intelligence of the water outlet temperature adjustment.

[0047] Please refer to Figure 2 , the second embodiment of the water temperature adjustment method in the embodiment of the present invention includes:

[0048] 201. In response to a mode selection instruction for a heat pump, determine the target operating mode corresponding to the mode selection instruction;

[0049] 202. Identify whether the target operating mode is executed for the first time in the heat pump to obtain an identification result;

[0050] 203. Based on the identification result, determine whether a preset control threshold is reached;

[0051] In this embodiment, it is determined whether the target operating mode determined by the heat pump is executed for the first time through the generated identification result.

[0052] Furthermore, step 202 may also be the number of executions of the target operating mode in the heat pump to obtain an identification result.

[0053] Furthermore, based on the identification result, determine whether a preset control threshold is reached.

[0054] Furthermore, by setting different control thresholds, the water outlet temperature control rule executed by the heat pump can be controlled.

[0055] 204. If not, determine the first water outlet temperature control rule executed by the heat pump based on the target operating mode;

[0056] In this embodiment, if the identification result determines that the preset control threshold is not reached, the first water outlet temperature control rule under the target operating mode is applied; if the identification result determines that the preset control threshold is reached, the second water outlet temperature control rule under the target operating mode is applied.

[0057] Furthermore, by adjusting the control threshold in step 203, different water outlet temperature control rules can be selected for application.

[0058] 205. If so, determine the second water outlet temperature control rule executed by the heat pump based on the target operating mode;

[0059] 206. When the outlet water temperature control rule is the first outlet water temperature control rule, obtain the first control parameter collected by the heat pump based on the first outlet water temperature control rule;

[0060] In this embodiment, when the outlet water temperature control rule is the first outlet water temperature control rule, obtain the first control parameter collected by the heat pump based on the determined first outlet water temperature control rule.

[0061] Furthermore, different target operating modes include corresponding first outlet water temperature control rules and second outlet water temperature control rules. The control rules contain corresponding control parameters. For example, the first outlet water temperature control rule contains the first control parameter. Collect the corresponding first control parameter through a sensor, and then determine the heating temperature of the heat pump based on the first control parameter.

[0062] In the actual application process, when the target operating mode is heating water outlet (automatic adjustment) and the first outlet water temperature control rule is applied, the first control parameter is the outdoor temperature collected by the heat pump.

[0063] In the actual application process, when the target operating mode is dehumidifying water outlet (automatic adjustment) and the first outlet water temperature control rule is applied, the first control parameter is the dew point temperature collected by the heat pump.

[0064] In the actual application process, when the target operating mode is cooling water outlet (automatic adjustment) and the first outlet water temperature control rule is applied, the first control parameter is the outdoor temperature collected by the heat pump.

[0065] 207. Determine the temperature coefficient of the heat pump based on the first outlet water temperature control rule;

[0066] In this embodiment, determine the corresponding temperature coefficient through the determined first outlet water temperature control rule.

[0067] Furthermore, the outlet water temperature control rule contains the corresponding temperature coefficient for controlling the outlet water temperature of the heat pump.

[0068] In the actual application process, when the target operating mode is cooling water outlet (automatic adjustment) and the first outlet water temperature control rule is applied, the temperature coefficient is 7. Furthermore, in combination with the first control parameter, if the first control parameter, i.e., the outdoor temperature, is not less than 35, the heating temperature is the temperature coefficient; furthermore, if the outdoor temperature is in the range of [25, 35], the heating temperature is -outdoor temperature + 42; furthermore, if the outdoor temperature is not greater than 25, the heating temperature is the temperature coefficient + 10.

[0069] In the actual application process, when the target working mode is heating water output (automatic regulation) and the first water output temperature control rule is applied, the temperature coefficient is 35. Further, in combination with the first control parameter, if the first control parameter, i.e., the outdoor temperature, is not less than 20, the heating temperature is the temperature coefficient; further, if the outdoor temperature is in the range of [-10, 20], the heating temperature is 0.5 times the outdoor temperature + 45; further, if the outdoor temperature is not greater than -10, the heating temperature is the temperature coefficient + 15.

[0070] In the actual application process, when the target working mode is dehumidifying water output (automatic regulation) and the first water output temperature control rule is applied, the temperature coefficient is 12. Further, in combination with the first control parameter, the first control parameter is the preset dehumidification temperature range. If the temperature coefficient is within the dehumidification temperature range, the heating temperature is the temperature coefficient; if the temperature coefficient is higher than the dehumidification temperature range, the heating temperature is the upper limit of the dehumidification temperature range; if the temperature coefficient is lower than the dehumidification temperature range, the heating temperature is the lower limit of the dehumidification temperature range.

[0071] 208. Control the heating temperature of the heat pump based on the first control parameter and the temperature coefficient;

[0072] 209. Determine the first adjustment range of the heat pump based on the first water output temperature control rule;

[0073] In this embodiment, there is also a first adjustment range of the heat pump. After obtaining the heating temperature for controlling the heat pump through step 208, it is judged whether the heating temperature is within the corresponding first adjustment range. If so, the heating temperature is applied; if the obtained heating temperature is higher than the first adjustment range of the corresponding target working mode, the upper limit value of the first adjustment range is applied as the heating temperature; if the obtained heating temperature is lower than the first adjustment range of the corresponding target working mode, the lower limit value of the first adjustment range is applied as the heating temperature.

[0074] 210. Judge whether the heating temperature is within the first adjustment range;

[0075] 211. If not, update the heating temperature based on the first adjustment range.

[0076] 212. Record the adjustment duration of the heat pump and judge whether the adjustment duration reaches the preset duration threshold;

[0077] In this embodiment, when the heat pump adjusts the outlet water temperature based on the first outlet water temperature control rule, record the adjustment duration of the heat pump. Wherein, the adjustment duration is the duration for the heat pump to heat the outlet water by updating the heating temperature in step 211. When the adjustment duration reaches the preset duration threshold, it is regarded as the execution times of the target working mode in the heat pump +1 or the execution times of the target working mode in the heat pump reaches the preset control threshold. Therefore, it is necessary to update the outlet water temperature control rule of the heat pump, that is, update the first outlet water temperature control rule of the heat pump applying the target working mode to the second outlet water temperature control rule corresponding to the target working mode. The heat pump controls the heat pump to update the heating temperature based on the second outlet water temperature control rule, and then adjusts the water temperature.

[0078] 213. If so, determine the second outlet water temperature control rule executed by the heat pump based on the target working mode;

[0079] 214. Control the heat pump to adjust the water temperature based on the second outlet water temperature control rule.

[0080] In the embodiment of the present invention, the present application determines the first adjustment interval of the heat pump based on the first outlet water temperature control rule; determines whether the heating temperature is within the first adjustment interval; if not, updates the heating temperature based on the first adjustment interval. This embodiment further limits the heating temperature generated in extreme cases by clarifying, preventing the heating temperature automatically generated in extreme environments from deviating from the normal use environment, and limiting the heating temperature by applying the first adjustment interval, improving the reliability of the heating temperature generation process.

[0081] Please refer to Figure 3 , the third embodiment of the water temperature adjustment method in the embodiment of the present invention includes:

[0082] 301. In response to the first control instruction for the heat pump, determine the target temperature adjustment mode corresponding to the first control instruction;

[0083] In this embodiment, the heat pump determines the target temperature adjustment mode corresponding to the first control instruction by responding to the first control instruction.

[0084] Specifically, the temperature adjustment modes include refrigeration, heating, and dehumidification. By responding to the first control instruction, select one of the modes as the target temperature adjustment mode.

[0085] 302. In response to the second control instruction for the heat pump, determine the target working setting mode corresponding to the second control instruction;

[0086] In this embodiment, the heat pump determines the target working setting mode corresponding to the second control instruction by responding to the second control instruction.

[0087] Specifically, the working setting mode includes automatic adjustment and manual setting. Only when the target working setting mode set by the second control instruction is automatic adjustment, the subsequent steps are triggered.

[0088] Furthermore, when the target working setting mode is manual setting, the heat pump does not adjust the outlet water temperature.

[0089] Furthermore, when the target working setting mode is manual setting, the heat pump can also determine the outlet water temperature based on the target working setting mode of automatic adjustment. After determining the outlet water temperature corresponding to the third control instruction in response to the third control instruction for the heat pump, the adjustment of the outlet water temperature is stopped, and the outlet water temperature is updated based on the third control instruction.

[0090] 303. Determine the target working mode that the heat pump executes through the target temperature adjustment mode and the target working setting mode;

[0091] In this embodiment, by determining the target temperature adjustment mode and the target working setting mode, the target working mode that the heat pump executes is determined.

[0092] 304. Identify whether the target working mode is executed for the first time in the heat pump to obtain an identification result;

[0093] 305. Judge whether a preset control threshold is reached based on the identification result;

[0094] 306. If not, determine the first outlet water temperature control rule that the heat pump executes based on the target working mode;

[0095] 307. If so, determine the second outlet water temperature control rule that the heat pump executes based on the target working mode;

[0096] 308. When the outlet water temperature control rule is the second outlet water temperature control rule, obtain the second control parameter collected by the heat pump based on the second outlet water temperature control rule;

[0097] In this embodiment, when the outlet water temperature control rule is the second outlet water temperature control rule, the second control parameter collected by the heat pump is obtained based on the determined second outlet water temperature control rule.

[0098] Furthermore, different target working modes include corresponding first outlet water temperature control rules and second outlet water temperature control rules. The control rules contain corresponding control parameters. For example, the first outlet water temperature control rule contains the first control parameter, and the corresponding first control parameter is collected by the sensor, and then the heating temperature of the heat pump is determined based on the first control parameter. Similarly, the second outlet water temperature control rule contains the second control parameter, and the corresponding second control parameter is collected by the sensor, and then the heating temperature of the heat pump is determined based on the second control parameter.

[0099] 309. Determine the second adjustment range and the corresponding additional coefficient of the heat pump based on the second outlet water temperature control rule;

[0100] In the actual application process, when the target working mode is heating water outlet (automatic adjustment) and the second outlet water temperature control rule is applied, the second control parameter is the overshoot of the most unfavorable AHU supply air temperature collected by the heat pump.

[0101] Further, the calculation method of the overshoot of the most unfavorable AHU supply air temperature is to calculate the overshoot of the supply air temperature in each room respectively and select the absolute value of the minimum value as the overshoot of the most unfavorable AHU supply air temperature, where the room is at least one room in which the heat pump is applied to execute the water temperature adjustment method to adjust the water temperature.

[0102] Specifically, the calculation method of the overshoot of the supply air temperature is to obtain the supply air temperature and the corresponding target supply air temperature in each room, and calculate the difference between the two supply air temperatures and the corresponding target supply air temperature in each room to obtain a set of overshoots of the supply air temperature, where the set of overshoots of the supply air temperature includes the overshoots of the supply air temperature in each room; screen the absolute value of the minimum value in the set of overshoots of the supply air temperature as the overshoot of the most unfavorable AHU supply air temperature in the heating water outlet (automatic adjustment) mode.

[0103] In the actual application process, when the target working mode is dehumidifying water outlet (automatic adjustment) and the second outlet water temperature control rule is applied, the second control parameter is the maximum overshoot of the dew point temperature in the room collected by the heat pump.

[0104] Further, the calculation method of the maximum overshoot of the dew point temperature in the room is to collect the overshoot of the dew point temperature in each room respectively, and screen the maximum value of the absolute value of the overshoot of the dew point temperature in each room as the maximum overshoot of the dew point temperature in the room in the dehumidifying water outlet (automatic adjustment) mode.

[0105] In the actual application process, when the target working mode is cooling water outlet (automatic adjustment) and the second outlet water temperature control rule is applied, the second control parameter is the overshoot of the most unfavorable AHU supply air temperature collected by the heat pump.

[0106] Further, the calculation method of the overshoot of the most unfavorable AHU supply air temperature is to calculate the overshoot of the supply air temperature in each room respectively and select the absolute value of the minimum value as the overshoot of the most unfavorable AHU supply air temperature, where the room is at least one room in which the heat pump is applied to execute the water temperature adjustment method to adjust the water temperature.

[0107] Specifically, the calculation method of the overshoot of the supply air temperature is to obtain the supply air temperature of each room and the corresponding target supply air temperature, and calculate the difference between the supply air temperature and the corresponding target supply air temperature in each room to obtain a set of supply air temperature overshoots, where the set of supply air temperature overshoots includes the supply air temperature overshoots of each room; the absolute value of the maximum value in the set of supply air temperature overshoots is selected as the most unfavorable AHU supply air temperature overshoot in the chilled water (automatic regulation) mode.

[0108] Specifically, AHU is (Air Handling Unit air handling unit)

[0109] 310. Determine the second adjustment interval corresponding to the second control parameter as the target interval;

[0110] In this embodiment, by determining the collected second control parameter and retrieving it in the second adjustment interval, it is judged whether the second control parameter is included in any second adjustment interval. When any second adjustment interval includes the collected second control parameter, the second adjustment interval is applied as the target interval.

[0111] In the actual application process, when the target working mode is chilled water (automatic regulation) and the second chilled water temperature control rule is applied, the temperature coefficient is 7, and the second adjustment interval is divided into [-0.5, 0.5], [0.5, 1.5], [>1.5], [< -1.5, -0.5], [< -1.5]. Further, when the target interval corresponding to the second control parameter is [-0.5, 0.5], the heating temperature is the temperature coefficient; when the target interval corresponding to the second control parameter is [0.5, 1.5], the heating temperature is the temperature coefficient - 1; when the target interval corresponding to the second control parameter is [>1.5], the heating temperature is the temperature coefficient - 2; when the target interval corresponding to the second control parameter is [< -1.5, -0.5], the heating temperature is the temperature coefficient + 1; when the target interval corresponding to the second control parameter is [< -1.5], the heating temperature is the temperature coefficient + 2.

[0112] In the actual application process, when the target working mode is heating water output (automatic regulation) and the second water output temperature control rule is applied, the temperature coefficient is 35, and the second adjustment interval is divided into [-0.5, 0.5], [0.5, 1.5], [>1.5], [< -1.5, -0.5], [< -1.5].
