[0001] This invention relates to the field of heat pump technology, and in particular to an environmental temperature adaptive control method, device, medium, electronic equipment, and heat pump. Background Technology

[0002] Air source heat pump units are known for their energy efficiency and environmental friendliness, and have been widely used in hotels, apartments, and residences in recent years for underfloor heating and fan coil cooling. In most engineering applications, the varying room temperature requirements of customers affect the room's operating load. Furthermore, due to differences in room structure and size, the operating load varies between rooms. This means that changes in outdoor temperature necessitate frequent adjustments to the unit's temperature settings by the customer, resulting in cumbersome operation. Summary of the Invention

[0003] The purpose of this invention is to provide an environmental temperature adaptive control method, device, medium, electronic equipment, and heat pump to solve the technical problems of frequent customer adjustments to the unit's set temperature and cumbersome operation in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] This invention provides a multi-room adaptive ambient temperature control method for air source heat pump units, comprising:

[0006] S1, Preset user habit parameters;

[0007] S2. Obtain the current outdoor temperature parameters;

[0008] S3. Based on the current outdoor temperature parameters and preset user habit parameters, obtain the start-up and operation parameters of the air source heat pump unit;

[0009] S4. After a set interval of △t, obtain the outdoor temperature parameter again;

[0010] S5. Based on the outdoor temperature parameters obtained again and the current outdoor temperature parameters obtained in step S2, the updated operating parameters of the air source heat pump unit are obtained.

[0011] S6. Compare the updated operating parameters with the actual operating parameters;

[0012] S7. Based on the comparison results, implement different temperature adjustment methods.

[0013] Based on the above technical solution, the present invention can be further improved as follows.

[0014] Furthermore, the preset user habit parameters include:

[0015] Monitor the outdoor temperature over a certain period of time, and then divide the monitored outdoor temperature into intervals and store them as outdoor temperature interval groups.

[0016] The system monitors indoor temperature over a period of time, divides the monitored indoor temperature into intervals, and stores them as indoor temperature interval groups, with each indoor temperature interval group corresponding to an outdoor temperature interval group.

[0017] Furthermore, obtaining the current outdoor temperature parameter includes:

[0018] Continuously monitor the current outdoor temperature parameter within a set time interval △t;

[0019] Based on continuously monitored current outdoor temperature parameters, calculate the current average outdoor temperature T0*, which is used as the first reference outdoor temperature.

[0020] Furthermore, based on the acquired current outdoor temperature parameters and preset user habit parameters, the start-up and operation parameters of the air source heat pump unit are obtained, including:

[0021] Based on the calculated first reference outdoor temperature, the corresponding outdoor temperature range group is matched;

[0022] Based on the matched outdoor temperature range group, the corresponding indoor temperature range group is obtained;

[0023] Based on the obtained indoor temperature range group, the average terminal set temperature is calculated and used as the first reference indoor temperature.

[0024] Based on the first reference indoor temperature, determine the initial load demand in the room;

[0025] Based on the determined initial load demand in the room, the outlet water temperature Tw* of the air source heat pump unit is determined;

[0026] The air source heat pump unit is controlled to operate at a predetermined outlet water temperature in order to perform preliminary indoor temperature regulation in each room.

[0027] Furthermore, after the set interval Δt, the outdoor temperature parameter is acquired again, including:

[0028] Continuously monitor outdoor temperature parameters within a set time interval △t;

[0029] The average outdoor temperature T01 is calculated based on continuously monitored outdoor temperature parameters.

[0030] Furthermore, the updated operating parameters of the air source heat pump unit are obtained based on the newly acquired outdoor temperature parameters and the current outdoor temperature parameters acquired in step S2, including:

[0031] Compare the calculated average outdoor temperature T01 with the first reference outdoor temperature T0*;

[0032] When |To1-To*|≤β, the first reference outdoor temperature T0* is determined not to be updated;

[0033] When |To1-To*|>β, the first reference outdoor temperature T0* is updated to the average outdoor temperature T01 calculated at interval set time △t, where β is the temperature correction coefficient;

[0034] Based on the determined first reference outdoor temperature, match the corresponding outdoor temperature range group;

[0036] Based on the obtained indoor temperature range group, the average terminal set temperature is calculated;

[0037] Determine the room load demand based on the average terminal set temperature;

[0038] Based on the determined room load requirements, the required outlet water temperature Tw of the air source heat pump unit is determined.

[0039] Furthermore, based on the comparison results, different temperature adjustment methods are implemented, including:

[0040] When the actual outlet water temperature Tc < the required outlet water temperature Tw, the unit capacity will continue to increase while maintaining the indoor set temperature.

[0041] When the actual outlet water temperature Tc is greater than or equal to the required outlet water temperature Tw, further adjustment is performed.

[0042] Furthermore, when the actual outlet water temperature Tc ≥ the required outlet water temperature Tw, further adjustment processing is performed, including:

[0043] Detect the actual indoor temperature Ti;

[0044] Calculate the temperature difference ΔTi between the indoor set temperature Ts and the actual indoor temperature Ti;

[0045] The calculated temperature difference ΔTi is compared with the preset temperature difference range (Tia, Tib); where Tia = 0, Tib - Tia = β;

[0046] When the air source heat pump unit is in heating mode, if ΔTi > Tib, the terminal set temperature is increased and the unit frequency is increased; if ΔTi ∈ (Tia, Tib), the terminal set temperature is not adjusted and the unit frequency is not adjusted; if ΔTi ≤ Tia, the terminal set temperature is decreased and the unit frequency is decreased.

[0047] When the air source heat pump unit is in cooling mode, if ΔTi>Tib, the terminal set temperature is lowered and the unit frequency is reduced; if ΔTi∈(Tia,Tib), the terminal set temperature is not adjusted and the unit frequency is not adjusted; if ΔTi≤Tia, the terminal set temperature is increased and the unit frequency is increased.

[0048] The air source heat pump unit provided by this invention is a multi-room ambient temperature adaptive control method. It is a control method that autonomously adjusts the set temperature of each room based on collecting user habit set temperatures and synchronously adjusts the load of each room. It can promptly determine the indoor comfort set temperature according to the user habit collection device and temperature calculation device to adjust the unit's capacity output. It can also promptly adjust the indoor temperature of each room according to the changes in the outdoor temperature of each room, ensuring user comfort and alleviating the need for users to frequently set the indoor temperature.

[0052] The first calculation unit is used to obtain the start-up and operation parameters of the air source heat pump unit based on the acquired current outdoor temperature parameters and preset user habit parameters;

[0053] The second acquisition unit is used to acquire the outdoor temperature parameter again after a set time interval △t;

[0054] The second calculation unit is used to obtain the updated operating parameters of the air source heat pump unit based on the outdoor temperature parameters obtained again and the current outdoor temperature parameters obtained in step S2.

[0055] The comparison unit is used to compare the updated operating parameters with the actual operating parameters;

[0056] The execution unit is used to execute different temperature adjustment methods based on the comparison results.

[0058] The present invention provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the method through the computer program.

[0059] The present invention provides a heat pump, which is an air source heat pump, for performing the method described above.

[0060] Furthermore, the heat pump includes an air source heat pump unit, a user habit collection device, and a room terminal device; the air source heat pump unit is connected to the terminal device via a circulating water pump; the user habit collection device is electrically connected to the terminal device.

[0061] Furthermore, the user habit collection device includes:

Detailed Implementation

[0075] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0076] like Figure 2 As shown, this invention provides a multi-room adaptive ambient temperature control method for air source heat pump units, comprising:

[0077] S1. Preset user habit parameters, including:

[0078] Monitor the outdoor temperature over a certain period of time, and then divide the monitored outdoor temperature into intervals and store them as outdoor temperature interval groups.

[0079] The system monitors the indoor temperature over a certain period of time, divides the monitored indoor temperature into intervals, and stores them as indoor temperature interval groups, with each indoor temperature interval group corresponding to an outdoor temperature interval group.

[0080] Specifically, before powering on, temperature collection devices are installed both indoors and outdoors for the user. The collected indoor and outdoor temperatures are then transmitted to the temperature storage devices corresponding to the user's collection devices.

[0081] S2. Obtain the current outdoor temperature parameters, including:

[0082] Continuously monitor the current outdoor temperature parameter within a set time interval △t;

[0083] Based on continuously monitored current outdoor temperature parameters, calculate the current average outdoor temperature T0*, which is used as the first reference outdoor temperature.

[0084] Specifically, before powering on, the outdoor temperature is recorded over a period of time. The average outdoor temperature over this time interval is calculated, and the time interval is denoted as Δt. This average outdoor temperature is recorded as the first reference outdoor temperature. After powering on, the average outdoor temperature is recalculated every Δt.

[0085] S3. Based on the acquired current outdoor temperature parameters and preset user habit parameters, obtain the start-up and operation parameters of the air source heat pump unit, including:

[0086] Based on the calculated first reference outdoor temperature, the corresponding outdoor temperature range group is matched;

[0087] Based on the matched outdoor temperature range group, the corresponding indoor temperature range group is obtained;

[0088] Based on the obtained indoor temperature range group, the average terminal set temperature is calculated and used as the first reference indoor temperature.

[0089] Based on the first reference indoor temperature, determine the initial load demand in the room;

[0090] Based on the determined initial load demand in the room, the outlet water temperature Tw* of the air source heat pump unit is determined;

[0091] The air source heat pump unit is controlled to operate at a predetermined outlet water temperature in order to perform preliminary indoor temperature regulation in each room.

[0092] Specifically, after powering on, the system compares the outdoor temperature range stored in the temperature storage device with the previously collected user-set terminal temperatures (i.e., the stored indoor temperature ranges) to calculate the average terminal set temperature for that indoor temperature range. This average terminal set temperature is recorded as the first reference indoor set temperature. The terminal is then turned on at the first reference indoor set temperature to determine the initial load demand in the room: Qn = Q(kn, Ts*, To*, qs), where Ts* is the first reference indoor set temperature, To* is the first reference outdoor temperature, kn is the heat transfer coefficient in the room (related to the room's internal structure), and qs is the solar radiation (related to the local climate). The same operation is performed on the remaining rooms to determine the total unit load: Qtotal = Q1 + Q2 + ... + Qn (where n is the total number of rooms). The total unit load determines the unit's outlet water temperature: Tw* = (Qtotal, f, To, q), where f is the optimal frequency corresponding to the total load, To is the average outdoor temperature calculated from the first reference outdoor temperature determined for all rooms, and q is the rated water flow rate. This outlet water temperature Tw* is then used to perform initial indoor temperature regulation in each room. It should be noted that the same average outdoor temperature may correspond to different user-set terminal temperatures; conversely, the same user-set terminal temperature may also correspond to different average outdoor temperatures. Therefore, a range is set based on the collected temperatures for calculation. After the control unit starts operating according to the startup parameters, indoor temperature adjustment is required, specifically as follows:

[0093] S4. After a set interval Δt, obtain the outdoor temperature parameters again, including:

[0094] Continuously monitor outdoor temperature parameters within a set time interval △t;

[0095] Based on continuously monitored outdoor temperature parameters, the average outdoor temperature T01 is calculated. That is, with Δt as the interval, the average outdoor temperature is confirmed by first determining the difference between the average outdoor temperature after the interval and the first reference outdoor temperature.

[0096] S5. Based on the newly acquired outdoor temperature parameters and the current outdoor temperature parameters acquired in step S2, the updated operating parameters of the air source heat pump unit are obtained, including:

[0097] Compare the calculated average outdoor temperature T01 with the first reference outdoor temperature T0*;

[0098] When |To1-To*|≤β, the first reference outdoor temperature T0* is determined not to be updated;

[0099] When |To1-To*|>β, the first reference outdoor temperature T0* is updated to the average outdoor temperature T01 calculated at intervals of a set time △t. Here, β is a temperature correction coefficient, which is related to the local temperature difference and is calculated based on the average temperature range of the previous week. It is set to 1 when the daily temperature difference is below 10℃, 2 when the daily temperature difference exceeds 10℃, and increases by 1 for every 5℃ increase thereafter, generally defaulting to 1.

[0100] Based on the determined first reference outdoor temperature, match the corresponding outdoor temperature range group;

[0101] Based on the matched outdoor temperature range group, the corresponding indoor temperature range group is obtained;

[0102] Based on the obtained indoor temperature range group, the average terminal set temperature is calculated;

[0103] Determine the room load demand based on the average terminal set temperature;

[0104] Based on the determined room load requirements, the required outlet water temperature Tw of the air source heat pump unit is determined.

[0105] S6. Compare the updated operating parameters with the actual operating parameters;

[0106] S7. Based on the comparison results, implement different temperature adjustment methods, including:

[0107] When the actual outlet water temperature Tc < the required outlet water temperature Tw, the room load will definitely not meet the calculation requirements if the unit capacity is insufficient. Therefore, the unit capacity will continue to be increased while maintaining the indoor set temperature.

[0108] When the actual outlet water temperature Tc is greater than or equal to the required outlet water temperature Tw, the room load may exceed the actual demand if the unit capacity is sufficient. Therefore, further adjustment is required here, specifically:

[0109] Detect the actual indoor temperature Ti;

[0110] Calculate the temperature difference ΔTi between the set indoor temperature Ts and the actual indoor temperature Ti; (ΔTi = Ts - Ti)

[0111] The calculated temperature difference ΔTi is compared with the preset temperature difference range (Tia, Tib); where, by default, Tia = 0 and Tib - Tia = β.

[0112] When the air source heat pump unit is in heating mode, if ΔTi > Tib, it indicates that the room load is insufficient, so the terminal set temperature is increased and the unit frequency is adjusted to increase; if ΔTi ∈ (Tia, Tib), the terminal set temperature is not adjusted and the unit frequency is not adjusted; if ΔTi ≤ Tia, it indicates that the room load exceeds the demand, so the terminal set temperature is decreased and the unit frequency is adjusted to decrease.

[0113] When the air source heat pump unit is in cooling mode, if ΔTi>Tib, it means that the room load exceeds the demand, so the terminal set temperature is lowered and the unit frequency is adjusted to decrease; if ΔTi∈(Tia,Tib), the terminal set temperature is not adjusted and the unit frequency is not adjusted; if ΔTi≤Tia, it means that the room load is insufficient, so the terminal set temperature is increased and the unit frequency is adjusted to increase.

[0114] The air source heat pump unit provided by this invention is a multi-room ambient temperature adaptive control method. It is a control method that autonomously adjusts the set temperature of each room based on collecting user habit set temperatures and synchronously adjusts the load of each room. It can promptly determine the indoor comfort set temperature according to the user habit collection device and temperature calculation device to adjust the unit's capacity output. It can also promptly adjust the indoor temperature of each room according to the changes in the outdoor temperature of each room, ensuring user comfort and alleviating the need for users to frequently set the indoor temperature.

[0115] Example 1:

[0116] like Figure 3 As shown, before powering on, temperature collection devices are installed both indoors and outdoors for the user. The collected indoor and outdoor temperatures are then transferred to the corresponding temperature storage devices.

[0117] Before powering on, record the outdoor temperature over a period of time. Calculate the average outdoor temperature over this time interval, denoted as Δt. This average outdoor temperature is recorded as the first reference outdoor temperature. After powering on, the average outdoor temperature is recalculated every Δt.

[0118] After startup, the average terminal set temperature is calculated by comparing the outdoor temperature range stored in the temperature storage device with the previously collected user-set terminal temperatures. This average terminal set temperature is recorded as the first reference indoor set temperature. The terminal is turned on at the first reference indoor set temperature to determine the initial load demand in the room: Qn = Q(kn, Ts*, To*, qs), where Ts* is the first reference indoor set temperature, To* is the first reference outdoor temperature, kn is the heat transfer coefficient in the room (related to the room's internal structure), and qs is the solar radiation (related to the local climate). The same operation is performed on the remaining rooms to determine the total unit load: Qtotal = Q1 + Q2 + ... + Qn (where n is the total number of rooms). The total unit load determines the unit outlet water temperature: Tw* = (Qtotal, f, To, q), where f is the optimal frequency corresponding to the total load, To is the average outdoor temperature calculated from the first reference outdoor temperature determined for all rooms, and q is the rated water flow rate. This outlet water temperature Tw* is used to perform initial indoor temperature regulation in each room.

[0119] During indoor temperature regulation, the average outdoor temperature is checked at intervals of Δt. First, the difference between the average outdoor temperature after the interval and the first reference outdoor temperature is checked.

[0120] When |To1-To*|≤β (β is the temperature correction factor, which is related to the local temperature difference and is calculated based on the average temperature difference range of the previous week. It is 1 when the daily temperature difference is less than 10℃, 2 when the daily temperature difference is more than 10℃, and increases by 1 for every 5℃ increase thereafter, and is generally taken as 1 by default), the outdoor reference temperature does not change.

[0121] When |To1-To*|>β, the outdoor reference temperature is updated to the outdoor reference temperature after the interval.

[0122] After confirming whether the outdoor reference temperature has been updated, compare the actual water outlet temperature in the room with the calculated water outlet temperature corresponding to the outdoor reference temperature, and set the actual water outlet temperature as Tc and the calculated water outlet temperature as Tw.

[0123] When Tc < Tw, if the unit capacity is insufficient, the room load will definitely not meet the calculation requirements, so the unit capacity will continue to be increased to maintain the indoor set temperature.

[0124] When Tc≥Tw, if the unit capacity is sufficient, the room load may exceed the actual demand, requiring analysis and adjustment of the actual situation.

[0125] The system detects the current indoor temperature and calculates the difference between the set temperature and the actual indoor temperature as ΔTi (ΔTi = Ts - Ti, where Ts is the set temperature of the room and Ti is the actual indoor temperature). It then determines the relationship between ΔTi and the temperature range (Tia, Tib), where Tib - Tia = β, with Tia set to 0 by default.

[0126] During heating, if ΔTi > Tib, it indicates insufficient room load; increase the terminal setpoint temperature and adjust the unit frequency accordingly. If ΔTi ∈ (Tia, Tib), the terminal setpoint temperature and unit frequency are not adjusted. If ΔTi ≤ Tia, it indicates insufficient room load; decrease the terminal setpoint temperature and adjust the unit frequency accordingly. During cooling, if ΔTi > Tib, it indicates insufficient room load; decrease the terminal setpoint temperature and adjust the unit frequency accordingly. If ΔTi ∈ (Tia, Tib), the terminal setpoint temperature and unit frequency are not adjusted. If ΔTi ≤ Tia, it indicates insufficient room load; increase the terminal setpoint temperature and adjust the unit frequency accordingly.

Before startup, by comparing the outdoor temperature with the user's preferred set temperature, the required load for each room is calculated to determine the total load of the unit and the outlet water temperature. After startup, the unit is first adjusted to the optimal frequency point corresponding to the calculated outlet water temperature. Then, based on the inlet and outlet water temperature difference during operation, the unit's operating frequency is further adjusted to ensure the unit reaches the required outlet water temperature as quickly as possible, meeting the adjustment needs of the terminal load in each room. By incorporating a user habit collection device and a temperature calculation device, the load demand of each room can be determined based on the calculated comfortable indoor set temperature, thereby adjusting the unit's capacity output and terminal load distribution, enabling users to independently adjust their indoor temperature and improving customer comfort.
