Description

Technical Field

[0001] This invention belongs to the field of temperature control technology, specifically relating to an energy-saving temperature control method for air source heat pumps, a network-connected temperature control method and temperature controller, and a temperature control system. Background Technology

[0002] An air source heat pump is an energy-saving device that utilizes high-grade energy to move heat from a low-grade heat source (air) to a high-grade heat source. The air source heat pump operates through a compressor system, absorbing heat from the air to produce hot water. Specifically, the compressor compresses the refrigerant, raising its temperature. This refrigerant then passes through a water tank to produce hot water. After heat exchange, the refrigerant returns to the compressor for the next cycle. During this process, heat from the air is absorbed by the evaporator into the refrigerant, which then enters the water, producing hot water.

[0003] In existing technologies, the water heating process of air-source heat pumps is relatively simple. When a temperature increase is needed, the air-source heat pump continuously heats the water until it reaches the maximum water temperature set by the heat pump, at which point heating stops. The indoor temperature is regulated by controlling the airflow. Clearly, the biggest drawback of this approach is the lack of effective water temperature control. For example, suppose raising the room temperature only requires raising the water temperature to 40 degrees Celsius, but the heat pump's maximum temperature is 50 degrees Celsius. In this case, the energy consumed to raise the water temperature from 40 degrees Celsius to 50 degrees Celsius is highly likely to be wasted. Summary of the Invention

[0004] One aspect of this disclosure provides an energy-saving temperature control method for an air source heat pump to solve the aforementioned technical problems.

[0005] The second aspect of this disclosure provides a network-connected air source heat pump energy-saving temperature control method, which further optimizes the temperature control effect through networking.

[0006] A third aspect of this disclosure provides a temperature controller.

[0007] The fourth aspect of this disclosure provides a temperature control system.

[0008] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] An energy-saving temperature control method for an air source heat pump includes the following steps:

[0010] Step 1: Preset the water temperature gauge;

[0011] Step 2: Obtain the outdoor temperature To and query the water temperature gauge to obtain the target water temperature Wt;

[0012] Step 3: Obtain the indoor temperature Ti and compare it with the target indoor temperature Tt to determine whether the water temperature needs to be increased.

[0013] If Ti≥Tt, there is no need to increase the water temperature; continue with the preceding steps in step 3.

[0014] If Ti < Tt, the water temperature needs to be increased and the subsequent procedure should be executed.

[0015] Step 4: Execute the intelligent water temperature control program, obtain the current indoor temperature Ti, and compare Ti with the target indoor temperature Tt:

[0016] If Ti < Tt, execute the timing temperature control program and the preceding program of step 4;

[0017] If Ti≥Tt, and the timer is on, turn off the timer and execute step 3 above;

[0018] in,

[0019] The intelligent water temperature control program includes:

[0020] Obtain the current water temperature Wc, compare Wc with the target water temperature Wt, and determine whether to continue heating.

[0021] If Wc < Wt, then the water temperature should be increased.

[0022] If Wc ≥ Wt, there is no need to heat the water.

[0023] The timed temperature control program includes:

[0024] If the timer is not started, start the timer;

[0025] If the timer expires, turn off the timer and pre-increase the target water temperature. Also, update the water temperature table with the outdoor temperature To corresponding to the target water temperature Wt, and update the target water temperature Wt with the pre-increase target water temperature that meets the conditions.

[0026] In some implementations, the method further includes step 5:

[0027] Obtain the difference Dt between the current indoor temperature Ti and the target indoor temperature Tt, and compare Dt with the interval value Tr of indoor temperature fluctuation.

[0028] If Dt > Tt, update the water temperature value corresponding to To in the water temperature table: divide the difference between Ti and Tt by 2 to get the adjustment coefficient Ct, subtract Ct from the water temperature value corresponding to To in the water temperature table to get the updated value, where Ct is rounded to the nearest integer and the minimum value is 1, and proceed to step 2;

[0029] If Dt≤Tr, proceed to step 3;

[0030] Accordingly, step 4 is adjusted to:

[0031] Step 4: Execute the intelligent water temperature control program, obtain the current indoor temperature Ti, and compare Ti with the target indoor temperature Tt:

[0032] If Ti < Tt, execute the timing temperature control program and the preceding program of step 4;

[0033] If Ti≥Tt, and the timer is on, turn off the timer and execute step 5 above.

[0034] In some implementations, step 3 is optimized by obtaining the indoor temperature Ti and comparing it with the target indoor temperature Tt to determine whether the water temperature needs to be increased.

[0035] If Ti < Tt, the water temperature needs to be increased and the subsequent procedure should be executed.

[0041] In some implementations, users can adjust the water temperature in the thermometer between the maximum water temperature value Wmax and the minimum water temperature value Wmin to meet the different needs of different users.

[0042] In some implementation schemes, when setting the indoor target temperature Tt, a determination is made between Tt and the indoor target standard temperature Tts.

[0043] If Tt > Tts, then the first water temperature fluctuation coefficient Wv1 is the value of the difference between the indoor target temperature Tt and Tts divided by 2; if Tt ≤ Tts, then Wv1 is 0.

[0044] Accordingly, the intelligent water temperature control program has been adjusted to:

[0045] Get the current water temperature Wc;

[0055] Comparing Wt+Wv2 and Wmax,

[0056] If Wt + Wv2 ≥ Wmax, then,

[0057] Compare Wc and Wmax. If Wc < Wmax, heat the water. If Wc ≥ Wmax, do not heat the water.

[0058] If Wt + Wv2 < Wmax, then,

[0067] If Wt + Wv1 + Wv2 < Wmax, then,

[0068] Compare Wc and Wt+Wv1+Wv2. If Wc < Wt+Wv1+Wv2, heat the water. If Wc ≥ Wt+Wv1+Wv2, do not heat the water.

The temperature control method of this application adopts intelligent regulation to optimize the target water temperature and water temperature gauge, which can control the water temperature at a relatively reasonable temperature, avoid energy waste caused by excessively high water temperature, and thus achieve the purpose of energy conservation and emission reduction.

The water temperature table has several sets of outdoor temperatures and corresponding water temperatures. The outdoor temperature is a temperature range. After obtaining the outdoor temperature, find out from the water temperature table which outdoor temperature range the current outdoor temperature falls into, and obtain the corresponding target water temperature value; execute S15;

[0094] If Ti < Tt, execute the timing temperature control program S3;

[0095] If Ti≥Tt, and the timer is on, turn off the timer and execute S15.

[0096] The water temperature gauge uses a preset range of values ​​based on regional characteristics to closely approximate the temperature variations of the application environment. However, the water temperature readings are only preset; they will be adjusted based on the implementation of this method to minimize energy consumption or quickly reach the desired indoor temperature, thus achieving energy savings or better temperature control.

[0097] The intelligent water temperature control program S2 includes the following steps:

[0098] Obtain the current water temperature Wc, compare Wc with Wt, and determine whether to continue heating.

[0099] If Wc < Wt, heat the water and execute S162;

[0100] If Wc ≥ Wt, stop heating and execute S162.

[0101] The timing and temperature control program S3 includes the following steps:

[0102] S31. Determine if the timer has started.

[0103] If so, execute S32;

[0104] If not, start the timer and execute S32;

[0105] S32. Determine if the timer has timed out.

[0106] If not, proceed to S161.

[0107] If so, turn off the timer and execute S33;

[0108] S33. Determine the pre-increase in water temperature, that is, compare Wt+Wr and Wmax.

[0109] If Wt+Wr<Wmax, then update the water temperature value corresponding to the outdoor temperature To in the water temperature table to Wt+Wr, increase the value of Wt by Wr, and execute S161;

[0110] If Wt + Wr ≥ Wmax, then update the water temperature value corresponding to the outdoor temperature To in the water temperature table to Wmax, increase the value of Wt to ​​Wmax, and execute S161.

[0111] In some embodiments, the temperature control method further includes:

[0112] S17. Obtain the difference Dt between Ti and Tt, and compare Dt with Tr.

[0113] If Dt > Tr, update the water temperature value corresponding to To in the water temperature table: divide the difference between Ti and Tt by 2 to get the adjustment coefficient Ct, and subtract Ct from the water temperature value corresponding to To in the water temperature table to get the updated value; where Ct is rounded to the nearest integer and the minimum value is 1; execute S13;

[0114] If Dt≤Tr, execute S15.

[0115] Accordingly, S163 is adjusted as follows:

[0116] Comparing Ti and Tt,

[0117] If Ti < Tt, execute the timing temperature control program S3;

[0118] If Ti≥Tt, and the timer is on, turn off the timer and execute S17.

[0119] In practical applications, the following optimization schemes are proposed for the above method in order to achieve better temperature control.

[0120] Optimization scheme 1: In some embodiments, it is necessary to control the minimum water temperature in the water circuit to prevent the water from freezing and damaging the pipes. To control the minimum water temperature, step S16 above is optimized as follows:

[0121] S16. Compare Ti and Tt to determine if the water temperature needs to be increased.

[0122] Comparing Ti and Tt,

[0123] If Ti < Tt, execute heating program S161;

[0124] If Ti≥Tt, execute the solid temperature program and S15;

[0125] The temperature control program includes:

[0126] Obtain the current water temperature Wc, and compare Wc with Wmin;

[0127] If Wc < Wmin, heat the water.

[0128] If Wc ≥ Wmin, stop heating.

[0129] In optimization scheme 2, in some embodiments, when setting the target temperature Tt in the system, the target value of the water temperature is further optimized. An indoor target standard temperature Tts is set for the indoor target temperature Tt, and a first water temperature fluctuation coefficient Wv1 is added. The first water temperature fluctuation coefficient Wv1 is determined as follows:

[0130] When setting Tt, Tt and Tts are determined.

[0131] If Tt > Tts, then Wv1 is the value of the difference between the indoor target temperature Tt and Tts divided by 2;

[0132] If Tt≤Tts, then Wv1 is 0.

[0133] Accordingly, the intelligent water temperature control program S2 needs to be adjusted:

[0134] S21. Obtain the current water temperature Wc, and execute S22.

[0135] S22. Compare Wt+Wv1 and Wmax.

[0136] If Wt+Wv1≥Wmax, then execute S23;

[0138] S23. Compare Wc and Wmax to determine whether to continue heating.

[0139] If Wc < Wmax, heat the water and execute S162.

[0140] If Wc ≥ Wmax, stop heating and execute S162.

[0141] S24. Compare Wc and Wt+Wv1 to determine whether to continue heating.

[0142] If Wc < Wt + Wv1, heat the water and execute S162;

[0143] If Wc≥Wt+Wv1, stop heating and execute S162.

[0144] In some embodiments of optimization scheme 3, users can adjust the water temperature value in the water temperature gauge between the maximum water temperature value Wmax and the minimum water temperature value Wmin to meet the different needs of different users.

[0145] This application provides a temperature control system, which includes a temperature controller as described herein and a remote server. The temperature controller also includes an internet unit, which connects wirelessly or via a wired connection, for example, using a WBR3 Graffiti WiFi module for remote access. The server sets water temperature fluctuation coefficients corresponding to the environment; for example, the water temperature fluctuation coefficient is 2 at night, and 3 on rainy days, etc. The server sets the water temperature fluctuation coefficients according to time and weather conditions. After the temperature controller connects to the server, it can obtain the local environment's corresponding water temperature fluctuation coefficient from the server.

[0146] Therefore, the temperature control method of this application can further dynamically adjust the target value of water temperature according to changes in the environment, and increase the second water temperature fluctuation coefficient Wv2 obtained from the server; under normal circumstances, the value of Wv2 is 0.

[0147] Accordingly, the intelligent water temperature control program S2 needs to be adjusted:

[0148] S21. Obtain the current water temperature Wc, and execute S22.

[0149] S22. Compare Wt+Wv2 and Wmax.

[0150] If Wt + Wv2 ≥ Wmax, then execute S23;

[0151] If Wt + Wv2 < Wmax, then execute S24.

[0152] S23. Compare Wc and Wmax to determine whether to continue heating.

[0153] If Wc < Wmax, heat the water and execute S162.

[0154] If Wc ≥ Wmax, stop heating and execute S162.

[0155] S24. Compare Wc and Wt+Wv2 to determine whether to continue heating.

[0156] If Wc < Wt + Wv2, heat the water and execute S162;

[0157] If Wc ≥ Wt + Wv2, stop heating and execute S162.

[0158] In some embodiments, if the first water temperature fluctuation coefficient Wv1 and the second water temperature fluctuation coefficient Wv2 exist simultaneously, the intelligent water temperature control program S2 needs to be adjusted:

[0159] S21. Obtain the current water temperature Wc, and execute S22.

[0160] S22. Compare Wt+Wv1+Wv2 and Wmax.

[0161] If Wt + Wv1 + Wv2 ≥ Wmax, then execute S23;

[0162] If Wt + Wv1 + Wv2 < Wmax, then execute S24.

[0163] S23. Compare Wc and Wmax to determine whether to continue heating.

[0164] If Wc < Wmax, heat the water and execute S162.

[0165] If Wc ≥ Wmax, stop heating and execute S162.

[0166] S24. Compare Wc and Wt+Wv2 to determine whether to continue heating.

[0167] If Wc < Wt + Wv1 + Wv2, heat the water and execute S162.

[0168] If Wc ≥ Wt + Wv1 + Wv2, stop heating and execute S162.

[0189] 117. Execute S16. Since Ti > Tt, there is no need to heat the water. Continue to execute S15.
