Description

COLD AND HOT WATER MACHINE AND PROCESSOR THEREOF, AND OPERATION
CONTROL METHOD
TECHNICAL FIELD
The present invention relates to the field of cold and hot water machines, in particular to a cold and hot water machine and a processor thereof, and an operation control method.
BACKGROUND ART
At present, an operation mode of a water machine is basically that a user sets the operation mode and water temperature in a turn-on state, and then a machine unit automatically controls the start and stop of the machine unit according to the set mode and water temperature, so that the water temperature reaches a set value. During the entire operation process of the machine unit, the setting temperature remains unchanged unless the user changes it. The above control method has the following problems: in order to avoid frequent setting of the water temperature while the user sets the temperature, the temperature setting is generally based on the temperature that may meet the indoor cooling or heating de- mand during the entire operation period, and the setting tempera- ture thereof often produces situations that the water temperature is lower while cooling, and the water temperature is higher when heating. The water temperature of the water machine is lower in a cooling state, the water temperature is higher while heating, and the energy efficiency is lower, so the machine unit consumes rela- tively more electricity while it is operated.
SUMMARY
In order to solve the above problems, a purpose of the pre- sent invention is to provide a cold and hot water machine with better energy efficiency and more energy saving and a processor thereof, and an operation control method.
In order to achieve the above purpose, the present invention adopts the following technical schemes: an operation control meth-
od of a cold and hot water machine, wherein the steps are as fol- lows:
Step 1): turning on the cold and hot water machine, and open- ing an energy-saving mode, wherein at this time, the cold and hot water machine detects and saves the existing outdoor temperature
Tw as a reference outdoor temperature Twl, and saves the existing return water setting water temperature Ts as a reference water temperature Tsl; and during the operation process of the cold and hot water machine, a user can adjust the return water setting wa- ter temperature Ts according to the actual usage requirements, at this time, the cold and hot water machine updates the reference outdoor temperature Twl and updates and saves the existing outdoor temperature Tw as a new reference outdoor temperature Twl, and the cold and hot water machine updates the reference water temperature
Tsl and saves the existing return water setting water temperature
Ts as a new reference water temperature Tsl;
Step 2): after setting a reference value, and after operating the cold and hot water machine for KO minutes by using the refer- ence value as a standard, performing a next operation;
Step 3): while the cold and hot water machine is in a cooling mode, if the outdoor ambient temperature Tw increases during the operation process of the cold and hot water machine, the return water setting water temperature Ts is not changed; if the outdoor ambient temperature Tw decreases, the return water setting water temperature Ts is improved; and once the existing return water setting water temperature Ts is determined, except for timing ad-
Justment or modifying the return water setting water temperature
Ts specified by the user, the cold and hot water machine can be operated for K3 minutes according to the existing return water setting water temperature Ts, wherein K3 is a constant; and
Step 4): while the cold and hot water machine is in a heating mode, if the outdoor ambient temperature Tw decreases during the operation process of the cold and hot water machine, the return water setting water temperature Ts is not changed; if the outdoor ambient temperature Tw increases, the return water setting water temperature Ts is reduced; and once the existing return water set- ting water temperature Ts is determined, except for timing adjust-
ment or modifying the return water setting water temperature Ts specified by the user, the cold and hot water machine can be oper- ated for K3 minutes according to the existing return water setting water temperature Ts.
Preferably, in the above Step 3), while the outdoor ambient temperature decreases, the cold and hot water machine needs to judge a degree of the decrease in the outdoor ambient temperature; while -Kl*TcSTw-Twl<0 is satisfied, wherein Tc is a cooling ad- justment parameter and Kl is a constant, it means that the de- crease of the ambient temperature at a room temperature is in a normal decrease range, and the existing return water setting water temperature Ts=Tsl+(Twl-Tw)/Tc; and while Tw-Twl<-Kl1*Tc is satis- fied, it means that the outdoor ambient temperature decreases in a wide range, then the existing return water setting water tempera- ture Ts is adjusted to Ts=Tsl+Kl (a calculation result is an inte- ger). In this way, according to a change condition of the outdoor temperature per unit time, the return water setting water tempera- ture is adjusted and controlled in detail, on the one hand, the power consumption is reduced, it is more energy-saving, and on the other hand, the compressor load may be reduced.
Preferably, in the above Step 3), if the return water setting water temperature Ts in an existing state reaches the maximum cooling return water setting water temperature Ts max-c of the cold and hot water machine, the existing return water setting wa- ter temperature Ts is set to be consistent with the maximum cool- ing return water setting water temperature Ts max-c. In this way, it is ensured that while the outdoor temperature decreases too much, a maximum setting temperature increase adjustment value is set, to avoid the setting water temperature from increasing too much, so that the compressor load is too small and the indoor ef- fect is unable to meet user needs.
Preferably, in the above Step 4), while the outdoor ambient temperature Tw increases, the cold and hot water machine needs to judge a degree of the increase in the outdoor ambient temperature
Tw; while K2*Th2Tw-Twl>0 is satisfied, wherein Th is a heating adjustment parameter and K2 is a constant, it means that the in-
crease of the ambient temperature at the room temperature is in a normal range, the existing return water setting water temperature
Ts=Tsl+(Twl-Tw)/Th; and while K2*Th<Tw-Twl is satisfied, it means that the outdoor ambient temperature increases in a wide range, then the existing return water setting water temperature is ad- justed to Ts=Tsl-K2 (a calculation result is an integer). In this way, according to the change condition of the outdoor temperature per unit time, the return water setting water temperature is ad- justed and controlled in detail, on the one hand, the power con- sumption is reduced, it is more energy-saving, and on the other hand, the compressor load may be reduced.
Preferably, in the above Step 4), if the existing return wa- ter setting water temperature Ts reaches the minimum heating re- turn water setting water temperature Ts min-h of the cold and hot water machine, the existing return water setting water temperature
Ts is set to be consistent with the minimum heating return water setting water temperature Ts min-h. In this way, it is ensured that while the outdoor temperature increases too much, a maximum setting temperature increase adjustment value is set, to avoid the setting water temperature from increasing too much, so that the indoor effect is unable to meet user needs.
A processor applies the above operation control method of the cold and hot water machine.
A cold and hot water machine applies the above operation con- trol method of the cold and hot water machine.
The beneficial effects of technical schemes of the present invention are as follows: 1. While the energy-saving mode is opened, the existing out- door ambient temperature Tw is automatically saved as the refer- ence outdoor temperature Twl, and the existing setting temperature
Ts is saved as Tsl. In this way, it is guaranteed that the user may change the reference value of the energy-saving adjustment ac- cording to the actual usage condition, and the accuracy of the reference value is improved. 2. In the present invention, after the reference value is set, and after the cold and hot water machine is operated for a period of time by using the reference value as the standard, the next operation is performed. In this way, a problem is avoided that while the user adjusts the setting temperature or the outdoor ambient temperature fluctuates, the control system automatically 5 adjusts the setting temperature according to an energy-saving rule, so that it is difficult for the user to set a desired refer- ence temperature, and the reference temperature does not meet the user requirements. 3. In the cooling mode, while the outdoor temperature de- creases, the return water setting temperature is improved; and in the heating mode, while the outdoor ambient temperature increases, the return water setting temperature is reduced. In this way, the energy efficiency of the machine unit is improved by at least 5%~10%, and the energy consumption of the machine unit is reduced by at least 5%, so the machine unit is efficient and energy- saving. 4. After the return water setting water temperature Ts is de- termined, except for timing adjustment or modifying the return wa- ter setting water temperature Ts specified by the user, the cold and hot water machine may be adjusted again after being operated for a period of time according to the existing return water set- ting water temperature Ts. In this way, the fluctuation of the setting temperature caused by the fluctuation of the outdoor ambi- ent temperature due to other reasons may be avoided, thereby the fluctuation of the machine unit control caused is avoided, and the increased load and instability of the machine unit are also avoid- ed.

Embodiment 1
An operation control method of a cold and hot water machine, the specific steps are as follows:
Step 1): turning on the cold and hot water machine, and open- ing an energy-saving mode, wherein at this time, the cold and hot water machine detects and saves the existing outdoor temperature
Tw as a reference outdoor temperature Twl, and saves the existing return water setting water temperature Ts as a reference water temperature Tsl; and during the operation process of the cold and hot water machine, a user can adjust the return water setting wa- ter temperature Ts according to the actual usage requirements, at this time, the cold and hot water machine updates the reference outdoor temperature Twl and updates and saves the existing outdoor temperature Tw as a new reference outdoor temperature Twl, and the cold and hot water machine updates the reference water temperature
Tsl and saves the existing return water setting water temperature
Ts as a new reference water temperature Tsl.
Step 2): after setting a reference value, and after operating the cold and hot water machine for KO minutes by using the refer- ence value as a standard, performing a next operation. In this way, it may be avoided that while the user adjusts the return wa- ter setting water temperature or the outdoor ambient temperature fluctuates, the user may not determine the desired reference value according to the actual situation. This setting is used to guaran- tee that the user obtains the best use experience.
Step 3): while the cold and hot water machine is in a cooling mode, if the outdoor ambient temperature Tw increases during the operation process of the cold and hot water machine, the return water setting water temperature Ts is not changed; if the outdoor ambient temperature Tw decreases, the return water setting water temperature Ts is improved; and once the existing return water setting water temperature Ts is determined, except for timing ad- jJustment or modifying the return water setting water temperature
Ts specified by the user, the cold and hot water machine may be operated for K3 minutes according to the existing return water setting water temperature Ts.
Step 4): while the cold and hot water machine is in a heating mode, if the outdoor ambient temperature Tw decreases during the operation process of the cold and hot water machine, the return water setting water temperature Ts is not changed; if the outdoor ambient temperature Tw increases, the return water setting water temperature Ts is reduced; and once the existing return water set- ting water temperature Ts is determined, except for timing adjust- ment or modifying the return water setting water temperature Ts specified by the user, the cold and hot water machine may be oper- ated for K3 minutes according to the existing return water setting water temperature Ts.
In the above Step 3), while the cooling mode and the energy- saving mode of the cold and hot water machine are opened at the same time, after the cold and hot water machine is operated for a period of time, if the cold and hot water machine detects that the outdoor ambient temperature Tw changes; while Tw-Twl20, it means that the outdoor ambient temperature increases, and the cold and hot water machine does not adjust the existing return water set- ting water temperature Ts, namely Ts=Tsl; while Tw-Tw1<0, it means that the outdoor ambient temperature decreases, and the cold and hot water machine needs to judge a degree of the decrease in the outdoor ambient temperature, and while -Kl*TcSTw-Twl<0 is satis- fied, wherein Tc is a cooling adjustment parameter and Kl is a constant, it means that the decrease of the ambient temperature at a room temperature is in a normal decrease range, and the existing return water setting water temperature Ts=Tsl+(Twl-Tw)/Tc (a cal- culation result is an integer); and while Tw-Twl<-K1*Tc is satis- fied, it means that the outdoor ambient temperature decreases in a wide range, then the existing return water setting water tempera- ture is adjusted to Ts=Tsl1+K1 (a calculation result is an inte- ger). If Ts=Tsl+K1>Ts max-c is satisfied, wherein Ts max-c is the maximum cooling return water setting water temperature, and the existing return water setting water temperature Ts=Ts max-c. In this way, it may be ensured that while the outdoor temperature de- creases too much, a maximum return water setting water temperature increase adjustment value is set, as to avoid the return water setting water temperature from increasing too much, so that the indoor effect may not meet user needs. In this embodiment, once the existing return water setting water temperature Ts is deter- mined, except for timing adjustment or modifying the return water setting water temperature Ts specified by the user, the cold and hot water machine may be operated for K3 minutes according to the existing return water setting water temperature Ts.
In the above step 4), while the heating mode and the energy- saving mode of the cold and hot water machine are opened at the same time, after the cold and hot water machine is operated for a period of time, if the cold and hot water machine detects that the outdoor ambient temperature changes; while Tw-Twl<0 is satisfied, it means that the outdoor ambient temperature decreases, then
Ts=Tsl is established, and the return water setting water tempera- ture Ts is not changed; while Tw-Twl>0 is satisfied, it means that the outdoor ambient temperature increases, then the return water setting water temperature Ts is correspondingly adjusted down.
While the outdoor ambient temperature increases, the cold and hot water machine needs to judge a degree of the increase in the out- door ambient temperature, and while K2*Th2Tw-Twl>0 is satisfied, wherein Th is a heating adjustment parameter and K2 is a constant, it means that the increase of the ambient temperature at the room temperature is in a normal range, and the existing return water setting water temperature Ts=Tsl+{(Twl-Tw)/Th (a calculation result is an integer); and while K2*Th<Tw-Twl is satisfied, it means that the outdoor ambient temperature increases in a wide range, then the existing return water setting water temperature is adjusted to
Ts=Ts1-K2 (a calculation result is an integer). In this way, by adjusting the return water setting water temperature in detail by the degree of the temperature change per unit time, on the one hand, the load of the cold and hot water may be reduced, and on the other hand, the purpose of energy saving is achieved by im- proving the return water setting water temperature. If
Ts=Tsl1-K2<Ts min-h is satisfied, wherein Ts min-h is the minimum heating return water setting water temperature, and the existing return water setting water temperature Ts=Ts min-h. In this embodiment, once the existing return water setting water tem- perature Ts is determined, except for timing adjustment or modify- ing the return water setting water temperature Ts specified by the user, the cold and hot water machine may be operated for K3 minutes according to the existing return water setting water tem- perature Ts.
A specific implementation example is as follows: the con- stants KO\KI\K2\K3 are set as: 5\4\6\30, Tc is 5, Th is 3, Tsmax-c is 20°C, and Tsmin-h is 30°C.
Example 1: in the cooling mode, the return water setting wa- ter temperature is 12°C, and the existing ambient temperature Tw is 35°C. The user opens the energy-saving mode at 9:30 in the turn-on state, the existing outdoor ambient temperature of 35°C is automatically saved as Twl (Twl=35°C), and the existing return wa- ter setting water temperature of 12°C is saved as the reference water temperature Tsl (Tsl=Ts=12°C); before 9:35, the user does not operate the return water setting water temperature. At 9:35, during a time period of 9:35-9:30, the cold and hot water machine does not make any adjustments, and the time that Tw and Ts remain unchanged is greater than or equal to 5 minutes. At 9:35, it is detected that the existing outdoor ambient temperature Tw is 35°C, because Tw-Twl=35-35=0, Tw-Twl20 is satisfied, so the return water setting water temperature Ts is not changed, namely Ts=Tsl=12°C.
Because Ts is 12°C, the setting of Ts>20°C is not satisfied, so
Ts=12°C. Before 10:05, since the user does not change the return water setting water temperature, the return water setting water temperature Ts is remained at 12°C. 10:06, 10:06-9:35=31 minutes is satisfied, the outdoor ambient temperature is detected again, it is assumed that the ambient temperature at this time is 30°C, because Tw-Tw1=30-35=-5°C, -20<Tw-Twl<0 is satisfied, then Ts=
Tsl+{(Twl-Tw)/Tc=12+(35-30)/5=13°C. Because Ts is 13°C, the set-
ting of Ts>20°C is not satisfied, so Ts=13°C. Every 30 minutes, the cold and hot water machine adjusts the return water setting water temperature according to the control method. If the user ad-
Justs the return water setting water temperature, Twl and Tsl are updated, and then the cold and hot water machine adjusts the re- turn water setting water temperature according to the control method.
Example 2: in the heating mode, the return water setting wa- ter temperature is 45°C, and the existing ambient temperature Tw is 0°C. The user opens the energy-saving mode at 9:30 in the turn- on state, the existing outdoor ambient temperature of 0°C is auto- matically saved as Twl {Twl=0°C), and the existing return water setting water temperature of 45°C is saved as the reference water temperature Tsl (Tsl=Ts=45°C). Subsequently, the user does not op- erate the return water setting water temperature. Before 9:35, the user does not operate the return water setting water temperature.
At 9:35, 9:35-9:30=5 minutes, it is satisfied that Tw and Ts re- main unchanged and the time is greater than or equal to 5 minutes.
It is detected that the existing outdoor ambient temperature Tw is 0°C, because Tw-Twl=0-0=0, Tw-Twl<0 is satisfied, so Ts=Ts1=45°C.
Because the existing return water setting water temperature Ts is 45°C, the setting of Ts<30°C is not satisfied, so Ts=45°C. Before 10:05, since the user does not change the return water setting wa- ter temperature, the return water setting water temperature Ts is remained at 45°C. 10:06, 10:06-9:35=31 minutes is satisfied, the outdoor ambient temperature is detected again, and it is assumed that the ambient temperature is 5°C at this time, because Tw-
Twl=5-0=5°C, 182Tw-Tw120 is satisfied, then Ts=Tsl+(Twl-Tw)/Tc= 45+({0-5)/3243.3°C=43°C (a calculation result is an integer), be- cause Ts is 43°C, the setting of Ts<30°C is not satisfied, so
Ts=43°C. Every 30 minutes, the cold and hot water machine adjusts the return water setting water temperature according to the con- trol method. If the user adjusts the return water setting water temperature, Twl and Tsl are updated, and then the cold and hot water machine adjusts the return water setting water temperature according to the control method.
This embodiment further includes a processor applying the above operation control method of the cold and hot water machine, and further includes a cold and hot water machine applying the above operation control method of the cold and hot water machine.
