The control method of the water multi-connected system can comprise the following steps: in steps S110 to S130.
At step S110, after the water multi-connected system is powered on, an operation mode of the water multi-connected system is determined. The operation modes can include: a cooling mode or a heating mode.
In step S120, in the cooling mode, the cooling temperature point shutdown temperature of the water multi-connected system in the cooling mode is determined according to the cooling water outlet temperature of the cold and hot water generator of the water multi-connected system. And the number of the first and second groups,
optionally, with reference to a flowchart of an embodiment of determining the refrigeration temperature point shutdown temperature of the water multi-connected system in the refrigeration mode in the method of the present invention shown in fig. 2, a specific process of determining the refrigeration temperature point shutdown temperature of the water multi-connected system in the refrigeration mode in step S120 may include: step S210 to step S230.
And step S210, acquiring the refrigerating outlet water temperature of the cold and hot water generator of the water multi-connected system according to a first set period in the refrigerating mode.
For example: starting the refrigerator in a refrigerating mode, and setting the temperature to be TIs provided withThe corresponding target water temperature is Tw-tar。
Step S220, determining whether the temperature of the refrigerating outlet water is continuously less than or equal to the target water temperature within a first set time period. The target water temperature may be a target water temperature corresponding to an indoor set temperature.
For example: in the refrigeration mode, the target water temperature T is measured at intervals of Tw-tarTemperature T of outlet water of cold and hot water generatorw-outOutdoor ambient temperature To-envAnd shutdown temperature T to temperature pointc-endAnd (4) carrying out primary judgment, wherein t is a detection judgment period of the temperature point.
Step S230, if the refrigerating outlet water temperature is continuously less than or equal to the target water temperature within the first set time, acquiring the outdoor environment temperature of the environment to which the water multi-connected system belongs, and determining the refrigerating temperature point shutdown temperature according to the outdoor environment temperature.
For example: under the refrigeration mode, when the temperature T of the outlet water of the cold and hot water generator is met by continuous detection for 1minw-outTarget ≦ targetWater temperature Tw-tarThen, the outdoor environment temperature T at this time is judgedo-envThe temperature range.
Of course, in the cooling mode, if the cooling outlet water temperature is continuously greater than the target water temperature within the first set time period, the multi-connected water system is controlled to maintain the current operation. For example: under the refrigeration mode, when the temperature T of the outlet water of the cold and hot water generator is met by continuous detection for 1minw-out> target Water temperature Tw-tarThen the current control is continued.
Therefore, the refrigeration temperature point shutdown temperature is determined according to the outdoor environment temperature under the condition that the refrigeration outlet water temperature is continuously smaller than or equal to the target water temperature within the first set time, so that the refrigeration temperature point shutdown temperature which changes along with the outdoor environment temperature in the refrigeration mode can be obtained, stable and safe control in the refrigeration mode is realized, and the improvement of the comfort experience of a user is facilitated.
More alternatively, the cooling temperature point shutdown temperature is determined according to the outdoor environment temperature in step S230, and any one of the following cooling determination situations may be included.
First refrigeration determination scenario: and if the outdoor environment temperature is less than the lower limit of the set refrigeration outdoor environment temperature range, determining the compensation temperature of the refrigeration temperature point shutdown temperature as a first set temperature, and taking the value obtained by subtracting the first set temperature from the target water temperature as the refrigeration temperature point shutdown temperature.
For example: under the refrigeration mode, when the temperature T of the outlet water of the cold and hot water generator is met by continuous detection for 1minw-outNot more than target water temperature Tw-tarIf the outdoor environment temperature T is at this momento-env< lower limit T of ambient temperature range outside refrigeration compartmento-c1If so, judging that the shutdown compensation temperature at the current temperature point is the first set temperature a, namely the shutdown temperature T at the refrigeration temperature pointc-endTarget water temperature Tw-tarA, determining that the water temperature reaches a temperature point, and executing corresponding shutdown control to the temperature point: the outdoor unit and the cold and hot water generator are stopped.
Second refrigeration determination scenario: and if the outdoor ambient temperature is greater than or equal to the lower limit of the set refrigeration outdoor ambient temperature range and less than or equal to the upper limit of the set refrigeration outdoor ambient temperature range, determining the compensation temperature of the refrigeration temperature point shutdown temperature as a second set temperature, and taking the value obtained by subtracting the second set temperature from the target water temperature as the refrigeration temperature point shutdown temperature.
For example: under the refrigeration mode, when the temperature T of the outlet water of the cold and hot water generator is met by continuous detection for 1minw-outNot more than target water temperature Tw-tarIf the lower limit T of the outdoor environment temperature range of the refrigeration at this time iso-c1Not more than outdoor environment temperature To-envUpper limit T less than or equal to ambient temperature range outside refrigerating chambero-c2If so, judging that the shutdown compensation temperature at the current temperature point is the second set temperature b, namely the shutdown temperature T at the refrigeration temperature pointc-endTarget water temperature Tw-tarB, determining that the water temperature reaches a temperature point, and executing corresponding shutdown control to the temperature point: the outdoor unit and the cold and hot water generator are stopped. Lower limit T of ambient temperature range outside refrigerating chambero-c1Upper limit of ambient temperature range T outside refrigeration chambero-c2And is the demarcation point of the outdoor environment temperature range of the refrigeration, namely the outdoor environment temperature range of the refrigeration.
A third refrigeration determination scenario: and if the outdoor environment temperature is greater than the upper limit of the set refrigeration outdoor environment temperature range, determining the compensation temperature of the refrigeration temperature point shutdown temperature as a third set temperature, and taking the value obtained by subtracting the third set temperature from the target water temperature as the refrigeration temperature point shutdown temperature.
For example: under the refrigeration mode, when the temperature T of the outlet water of the cold and hot water generator is met by continuous detection for 1minw-outNot more than target water temperature Tw-tarIf the outdoor environment temperature T is at this momento-envGreater than the upper limit T of the ambient temperature range outside the refrigeration compartmento-c2If so, judging that the shutdown compensation temperature at the current temperature point is the third set temperature c, namely the shutdown temperature T at the refrigeration temperature pointc-endTarget water temperature Tw-tarC, determining that the water temperature reaches a temperature point, and executing corresponding shutdown control to the temperature point: the outdoor unit and the cold and hot water generator are stopped.
Therefore, under the condition that the temperature of the refrigerating outlet water is continuously less than or equal to the target water temperature within the first set time, the refrigerating temperature point shutdown temperature is determined according to different temperature intervals of the outdoor environment temperature, the refrigerating temperature point shutdown temperature in different outdoor environment temperature intervals in the refrigerating mode can be accurately obtained, and stable and reliable operation and shutdown control of the water multi-connected system in the refrigerating mode are achieved.
In step S130, in a case that the water temperature of the water multi-connected system reaches the refrigeration temperature point shutdown temperature, the external unit and the hot and cold water generator of the water multi-connected system are controlled to shutdown, so as to control the refrigeration operation process of the water multi-connected system.
In step S140, in the heating mode, a heating temperature point shutdown temperature of the water multi-connected system in the heating mode is determined according to a heating outlet water temperature of a hot and cold water generator of the water multi-connected system. And the number of the first and second groups,
optionally, with reference to a flowchart of an embodiment of determining the heating temperature point shutdown temperature of the water multi-connected system in the heating mode in the method of the present invention shown in fig. 3, a specific process of determining the heating temperature point shutdown temperature of the water multi-connected system in the heating mode in step S140 may further be described, where the specific process includes: step S310 to step S330.
And step S310, acquiring the heating water outlet temperature of the cold and hot water generator of the multi-connected system according to a second set period in the heating mode.
For example: starting up in heating mode, setting temperature as TIs provided withThe corresponding target water temperature is Tw-tar。
And step S320, determining whether the heating water outlet temperature is continuously greater than or equal to the target water temperature within a second set time length. The target water temperature may be a target water temperature corresponding to an indoor set temperature.
For example: in the heating mode, the set temperature T is adjusted at intervals of TIs provided withTemperature T of outlet water of cold and hot water generatorw-outOutdoor ambient temperature To-envAnd shutdown temperature T to temperature pointh-endAnd performing one judgment t as a temperature point detection judgment period.
Step S330, if the heating outlet water temperature is continuously less than or equal to the target water temperature within the second set time, acquiring the outdoor environment temperature of the environment to which the water multi-connected system belongs, and determining the heating temperature point shutdown temperature according to the outdoor environment temperature.
For example: under the heating mode, continuously detecting the temperature T of the outlet water of the cold and hot water generator for 1minw-outNot less than target water temperature Tw-tarThen, the outdoor environment temperature T at this time is judgedo-envThe temperature range.
Of course, in the heating mode, if the heating outlet water temperature is continuously lower than the target water temperature within the second set time period, the water multi-connected system is controlled to maintain the current operation. For example: under the heating mode, when the temperature T of the outlet water of the cold and hot water generator is met by continuous detection for 1minw-out< target Water temperature Tw-tarThen the current control is continued.
Therefore, under the condition that the heating outlet water temperature is continuously greater than or equal to the target water temperature within the second set time, the heating temperature point shutdown temperature is determined according to the outdoor environment temperature, and the heating temperature point shutdown temperature which changes along with the outdoor environment temperature in the heating mode can be obtained, so that the heating mode is stably and safely controlled, and the comfort experience of a user is favorably improved.
More alternatively, the heating temperature point shutdown temperature is determined according to the outdoor environment temperature in step S330, and any one of the following heating determination situations may be included.
First heating determination case: and if the outdoor environment temperature is less than the lower limit of the set heating outdoor environment temperature range, determining the compensation temperature of the heating temperature point shutdown temperature as a fourth set temperature, and increasing the value of the target water temperature by the fourth set temperature to be used as the heating temperature point shutdown temperature.
For example: under the heating mode, continuously detecting the temperature T of the outlet water of the cold and hot water generator for 1minw-outNot less than target water temperature Tw-tarIf the outdoor environment temperature T is at this momento-env< lower limit T of ambient temperature range outside heating chambero-h1If the temperature is lower than the first set temperature, the shutdown compensation temperature is judged to be the third set temperature d, namely the shutdown temperature T is judged when the temperature is heated to the temperature pointh-endTarget water temperature Tw-tarWhen + d, the water temperature is judged to reach the temperature point, and the corresponding shutdown control to the temperature point is executed: the outdoor unit and the cold and hot water generator are stopped.
Second heating determination case: and if the outdoor environment temperature is greater than or equal to the lower limit of the set heating outdoor environment temperature range and less than or equal to the upper limit of the set heating outdoor environment temperature range, determining the compensation temperature of the heating temperature point shutdown temperature as a fifth set temperature, and taking the value of the target water temperature increased by the fifth set temperature as the heating temperature point shutdown temperature.
For example: under the heating mode, continuously detecting the temperature T of the outlet water of the cold and hot water generator for 1minw-outNot less than target water temperature Tw-tarIf the lower limit T of the ambient temperature range outside the heating chamber is reached at this timeo-h1Not more than outdoor environment temperature To-envUpper limit T less than or equal to the ambient temperature range outside the heating chambero-h2If the temperature is lower than the first set temperature, the shutdown compensation temperature is judged to be the second set temperature e, namely the shutdown temperature T is judged to be the second set temperature when the temperature is lower than the first set temperatureh-end=Tw-tarAnd e, judging that the water temperature reaches a temperature point, and executing corresponding shutdown control to the temperature point: the outdoor unit and the cold and hot water generator are stopped. Lower limit T of ambient temperature range outside heating chambero-h1Upper limit T of ambient temperature range outside heating chambero-h2The boundary point is the boundary point of the heating outdoor environment temperature range, i.e. the heating outdoor environment temperature interval.
The third heating determination scenario: and if the outdoor environment temperature is greater than the upper limit of the set heating outdoor environment temperature range, determining the compensation temperature of the heating temperature point shutdown temperature as a sixth set temperature, and taking the value of the target water temperature increased by the sixth set temperature as the heating temperature point shutdown temperature.
For example: under the heating mode, continuously detecting the temperature T of the outlet water of the cold and hot water generator for 1minw-outNot less than target water temperature Tw-tarIf the outdoor environment temperature T is at this momento-envGreater than the upper limit T of the ambient temperature interval outside the heating chambero-h2If the temperature is lower than the first set temperature f, the shutdown compensation temperature is judged to be the fifth set temperature f, namely the shutdown temperature T is judged when the temperature is heated to the temperature pointh-end=Tw-tarWhen + f, judge that the water temperature reaches the temperature point, carry out the shutdown control corresponding to the temperature point: the outdoor unit and the cold and hot water generator are stopped. d. e and f are the shutdown compensation temperature when the heating reaches the temperature point.
Therefore, under the condition that the heating outlet water temperature is continuously greater than or equal to the target water temperature within the second set time length, the heating temperature point shutdown temperature is determined according to different temperature intervals of the outdoor environment temperature, the heating temperature point shutdown temperature in different outdoor environment temperature intervals in the heating mode can be accurately obtained, and stable and reliable operation and shutdown control of the water multi-connected system in the heating mode are achieved.
In step S150, when the water temperature of the water multi-connected system reaches the shutdown temperature of the heating temperature point, the outdoor unit and the hot and cold water generator of the water multi-connected system are controlled to shutdown, so as to control the heating operation process of the water multi-connected system.
For example: the compensation value from the water temperature to the temperature point is set to be intelligently controlled, the compensation value can change in real time according to the environment condition of external change, and better experience is provided for users. If the compensation temperature that the temperature of accessible environmental condition automatically regulated temperature reached the temperature point and shut down, control is more energy-conserving, user's travelling comfort experiences better.
For example: can be to different external environment temperature, the compensation temperature that the intelligent control shut down to the temperature point reaches compensation temperature after, outer machine and cold and hot water generator just shut down, can guarantee like this: in the refrigeration mode, the machine cannot be frequently stopped when the outside is high in temperature, so that the water temperature is rebounded, the indoor environment temperature is increased, the user experience is poor, the refrigeration is not excessive when the outside is low in temperature, and the energy is wasted; the heating mode does not excessively heat at high external temperature, wastes energy, does not frequently stop at low external temperature, and causes the water temperature to rebound, thereby reducing the indoor environment temperature and having poor user experience; thereby better promoting the user's travelling comfort under the refrigeration heating mode and experiencing, and be favorable to energy-conservation.
Therefore, the shutdown temperature of the temperature point is determined according to the outlet water temperature of the cold and hot water generator in the cooling and heating mode, the outdoor unit and the cold and hot water generator of the water multi-connected system are controlled to be shut down under the condition that the water temperature reaches the shutdown temperature of the heating temperature point, the situation that the user experience is influenced and electricity is consumed due to frequent shutdown of the water multi-connected system can be avoided, the use experience of a user is improved, and energy is saved.
Through a large amount of experimental verifications, adopt the technical scheme of this embodiment, but through setting up the compensation value of temperature to the temperature point into intelligent control, the compensation value can realize real-time change according to the ambient condition of external world change, can provide better comfortable nature experience for the user.
