Description
Technical Field
The invention relates to the field of water chiller-heater, in particular to a water chiller-heater, a processor thereof and an operation control method thereof.
Background
The current running mode of the water machine basically is that after the running mode and the water temperature are set by a user in a starting state, the machine set is automatically controlled to start and stop according to the set mode and the water temperature, so that the water temperature reaches a set value. In the whole running process of the unit, the set temperature is kept unchanged unless the user changes. The control method has the following problems: in order to avoid frequent setting of water temperature when the user sets the temperature, the temperature is generally set according to the indoor cooling capacity or heat demand during the whole operation period, and the set temperature is usually lower when the water temperature is refrigerated and higher when the water temperature is heated. The lower the water temperature of the water machine in the refrigeration state is, the higher the water temperature of the water machine in the heating state is, the lower the energy efficiency is, so that the unit relatively consumes power in operation.
Disclosure of Invention
In order to solve the problems, the invention aims to provide a water chiller-heater with better energy efficiency and more energy saving, a processor thereof and an operation control method thereof.
In order to achieve the above purpose, the present invention adopts the following technical scheme: the operation control method of the water chiller-heater comprises the following steps:
step 1): the cold and hot water machine is started, the energy-saving mode is started, at the moment, the cold and hot water machine detects and stores the current outdoor temperature Tw as a reference outdoor temperature Tw1, and the current backwater set water temperature Ts is stored as a reference water temperature Ts1; in the running process of the cold and hot water machine, a user can adjust the backwater setting water temperature Ts according to actual use requirements, at the moment, the cold and hot water machine updates the reference outdoor temperature Tw1 and stores the current outdoor temperature Tw as a new reference outdoor temperature Tw1, and the cold and hot water machine updates the reference water temperature Ts1 and stores the current backwater setting water temperature Ts as a new reference water temperature Ts1;
step 2): after the reference value is set, the cold and hot water machine runs for K0 minutes based on the reference value, and then the next action is carried out;
step 3): when the cold and hot water machine is in a refrigerating mode, if the outdoor environment temperature Tw is increased in the running process of the cold and hot water machine, the backwater setting water temperature Ts is not changed; if the outdoor ambient temperature Tw decreases, the return water set water temperature Ts increases. If the backwater set water temperature Ts in the current state reaches the refrigeration highest backwater set water temperature Ts of the cold-hot water machine max-c When the current backwater setting water temperature Ts is equal to the refrigeration highest backwater setting water temperature Ts max-c . Once the current backwater set water temperature Ts is determined, except for timing adjustment or user specified modification of the backwater set water temperature Ts, the cold and hot water can be operated for K3 minutes according to the current backwater set water temperature Ts, and K3 is a constant;
step 4): when the water chiller-heater is in a heating mode, if the outdoor environment temperature Tw is reduced in the running process of the water chiller-heater, the backwater setting water temperature Ts is not changed; if the outdoor ambient temperature Tw increases, the return water setting water temperature Ts decreases. If the current backwater set water temperature Ts reaches the heating minimum backwater set water temperature Ts of the water chiller-heater min-h When the water temperature is equal to the heating lowest water temperature min-h The method comprises the steps of carrying out a first treatment on the surface of the Once the current backwater setting water temperature Ts is determined, the backwater is modified by timing adjustment or user specificationOutside the water set water temperature Ts, the cold and hot water can be operated for K3 minutes according to the current backwater set water temperature Ts.
Preferably, in the step 3), when the outdoor ambient temperature decreases, the water chiller/heater needs to determine the degree of decrease in the outdoor ambient temperature, and when-k1×tc is less than or equal to Tw-Tw1 < 0, tc is a refrigeration adjustment parameter, K1 is a constant, indicating that the decrease in the room ambient temperature is in a normal decrease range, and the current backwater setting water temperature ts=ts1+ (Tw 1-Tw)/Tc (the calculation result is an integer); when Tw-Tw1 < -K1 Tc is satisfied, indicating that the outdoor ambient temperature is greatly reduced, the current backwater setting water temperature is adjusted to ts=ts1+k1 (the result of calculation is an integer). Therefore, according to the change condition of the temperature outside the inner chamber in unit time, the water temperature is adjusted and controlled in detail, so that the power consumption is reduced, the energy is saved, and the load of the compressor is reduced.
Preferably, in the step 3), if the backwater setting water temperature Ts in the current state reaches the maximum backwater setting water temperature Ts for cooling the water heater max-c When the water temperature is set to be equal to the maximum water temperature Ts max-c And consistent. Therefore, under the condition that the outdoor temperature is excessively reduced, a maximum set temperature lifting adjustment value is set, and the situation that the set water temperature is excessively lifted, so that the effect that the compressor is excessively small in load and cannot meet the user requirement is avoided.
Preferably, in the step 4), when the outdoor ambient temperature Tw increases, the hot and cold water machine needs to determine the degree of lift of the outdoor ambient temperature Tw, and when the degree of lift satisfies k2×th is greater than or equal to Tw-Tw1 > 0, where Th is a heating adjustment parameter, and K2 is a constant, and indicates that the room ambient temperature increases in a normal range, the current backwater setting water temperature ts=ts1+ (Tw 1-Tw)/Th (the result of calculation is an integer); when the temperature satisfies k2×th < Tw-Tw1, it indicates that the outdoor ambient temperature rises widely, and the current backwater setting water temperature is adjusted to ts=ts1-K2 (the calculation result is an integer). Therefore, according to the change condition of the temperature outside the inner chamber in unit time, the water temperature is adjusted and controlled in detail, so that the power consumption is reduced, the energy is saved, and the load of the compressor is reduced.
Preferably, in the step 4), if the current backwater setting water temperature Ts reaches the heating minimum backwater setting water temperature Ts of the water chiller-heater min-h When the water temperature is set to be equal to the heating lowest water temperature min-h And consistent. Therefore, under the condition that the outdoor temperature rises excessively, a maximum set water temperature rising adjustment value is set, and the problem that the indoor effect cannot meet the requirement of a user due to too much rising of the set water temperature is avoided.
A processor applies the operation control method of the water chiller-heater.
A cold and hot water machine is applied to the operation control method of the cold and hot water machine.
The technical scheme of the invention has the beneficial effects that:
1. when the energy-saving mode is started, the current outdoor environment temperature Tw is automatically saved as the reference outdoor temperature Tw1, and the current set temperature Ts is saved as Ts1, so that the user can change the reference value of energy-saving adjustment according to the actual use condition, and the accuracy of the reference value is improved.
2. After the reference value is set, the water chiller/heater runs for a period of time based on the reference value, and then performs the next action. Therefore, when the user adjusts the set temperature or the outdoor environment temperature fluctuates, the control system automatically adjusts the set temperature according to the energy-saving rule, so that the user is difficult to set the desired reference temperature, and the problem that the reference temperature is inconsistent with the user requirement is avoided.
3. In the refrigeration mode, when the outdoor temperature is reduced, the backwater set temperature is increased; in the heating mode, when the outdoor environment temperature is increased, the backwater set temperature is reduced. Therefore, the energy efficiency of the unit is improved by at least 5% -10%, and the energy consumption of the unit is reduced by at least 5%, so that the unit is efficient and energy-saving.
4. When the backwater set water temperature Ts is determined, except for timing adjustment or user designated modification of the backwater set water temperature Ts, the cold and hot water can be adjusted again after running for a period of time according to the current backwater set water temperature Ts. Therefore, the fluctuation of the set temperature caused by the fluctuation of the outdoor environment temperature due to other reasons can be avoided, the fluctuation of the control of the unit is caused, and the load and the instability of the unit are also avoided.

Example 1
The operation control method of the water chiller-heater comprises the following specific steps:
step 1): the cold and hot water machine is started, the energy-saving mode is started, at the moment, the cold and hot water machine detects and stores the current outdoor temperature Tw as a reference outdoor temperature Tw1, and the current backwater set water temperature Ts is stored as a reference water temperature Ts1; in the running process of the water chiller-heater, a user can adjust the backwater setting water temperature Ts according to actual use requirements, at the moment, the water chiller-heater updates the reference outdoor temperature Tw1 and stores the current outdoor temperature Tw as a new reference outdoor temperature Tw1, and the water chiller-heater updates the reference water temperature Ts1 and stores the current backwater setting water temperature Ts as a new reference water temperature Ts1.
Step 2): after the reference value is set, the water chiller/heater is operated for K0 minutes based on the reference value, and then the next operation is performed. Therefore, the situation that the user cannot determine the reference value of the centering instrument according to actual conditions when the user adjusts the backwater to set water temperature or the outdoor environment temperature fluctuates can be avoided, and the setting is used for ensuring that the user obtains optimal use experience.
Step 3): when the cold and hot water machine is in a refrigerating mode, if the outdoor environment temperature Tw is increased in the running process of the cold and hot water machine, the backwater setting water temperature Ts is not changed; if the outdoor ambient temperature Tw decreases, the return water set water temperature Ts increases. If the current state isThe lower backwater set water temperature Ts reaches the refrigeration highest backwater set water temperature Ts of the cold-hot water machine max-c When the current backwater setting water temperature Ts is equal to the refrigeration highest backwater setting water temperature Ts max-c . Once the current backwater setting water temperature Ts is determined, the cold and hot water can be operated for K3 minutes according to the current backwater setting water temperature Ts except for timing adjustment or user-specified modification of the current backwater setting water temperature Ts.
Step 4): when the water chiller-heater is in a heating mode, if the outdoor environment temperature Tw is reduced in the running process of the water chiller-heater, the backwater setting water temperature Ts is not changed; if the outdoor ambient temperature Tw increases, the return water setting water temperature Ts decreases. If the current backwater set water temperature Ts reaches the heating minimum backwater set water temperature Ts of the water chiller-heater min-h When the water temperature is equal to the heating lowest water temperature min-h . Once the current backwater setting water temperature Ts is determined, the cold and hot water can be operated for K3 minutes according to the current backwater setting water temperature Ts except for timing adjustment or user-specified modification of the backwater setting water temperature Ts.
In the step 3), when the cooling mode and the energy-saving mode of the water chiller are simultaneously started, after the water chiller runs for a period of time, if the water chiller detects that the outdoor environment temperature Tw changes; when Tw-Tw1 is more than or equal to 0, the outdoor environment temperature is increased, and the water chiller-heater does not adjust the current backwater set water temperature Ts, namely Ts=T1; when Tw-Tw1 is less than 0, the outdoor environment temperature is reduced, and the water chiller-heater improves the current backwater setting water temperature Ts. When the outdoor environment temperature is reduced, the cold and hot water machine needs to judge the degree of the reduction of the outdoor environment temperature, and when-K1 is satisfied that Tc is less than or equal to Tw-Tw1 and less than 0, tc is a refrigeration adjustment parameter, K1 is a constant, the reduction of the room temperature environment temperature is in a normal reduction range, and the current backwater setting water temperature Ts=T1+ (Tw 1-Tw)/Tc (the calculated result is an integer); when Tw-Tw1 < -K1 Tc is satisfied, indicating that the outdoor ambient temperature is greatly reduced, the current backwater setting water temperature is adjusted to ts=ts1+k1 (the result of calculation is an integer). If ts=ts1+k1 > Ts is satisfied max-c In which Ts is max-c Setting water temperature for the highest backwater of refrigeration, and setting water temperature Ts=Ts for the current backwater max-c . In this way the first and second light sources,the method can ensure that under the condition that the outdoor temperature is excessively reduced, a maximum backwater setting water temperature lifting adjustment value is set, and the condition that the backwater setting water temperature is lifted too much to cause that the indoor effect cannot meet the requirement of a user is avoided. In this embodiment, once the current backwater setting water temperature Ts is determined, the hot and cold water will run for K3 minutes according to the current backwater setting water temperature Ts, except for the timing adjustment or the user-specified modification of the backwater setting water temperature Ts.
In the step 4), when the heating mode and the energy-saving mode of the water chiller are simultaneously started, after the water chiller runs for a period of time, if the water chiller detects that the outdoor environment temperature changes; when Tw-Tw1 is less than or equal to 0, indicating that the outdoor environment temperature is reduced, then Ts=Ts1 is established, and the backwater setting water temperature Ts is not changed; when Tw-Tw1 is more than 0, the outdoor environment temperature is increased, and the backwater setting water temperature Ts is correspondingly adjusted downwards. When the outdoor environment temperature rises, the cold and hot water machine needs to judge the rising degree of the outdoor environment temperature, when the rising degree of the outdoor environment temperature meets the requirement that K2 is more than or equal to Tw-Tw1 and more than 0, wherein Th is a heating adjustment parameter, K2 is a constant, the rising of the room temperature environment temperature is in a normal range, and the current backwater setting water temperature Ts=T1+ (Tw 1-Tw)/Th (the calculated result is an integer); when K2 Th < Tw-Tw1 is satisfied, indicating that the outdoor environment temperature rises in a large range, and adjusting the current backwater setting water temperature to be Ts=Ts1-K2 (the calculated result is an integer); therefore, the load of the cold and hot water machine can be reduced on one hand, and the purpose of saving energy is achieved by increasing the backwater setting water temperature on the other hand by adjusting the backwater setting water temperature according to the degree detail of temperature change in unit time. If ts=ts1-K2 < Ts is satisfied min-h In which Ts is min-h Setting water temperature for heating the lowest backwater, and setting water temperature Ts=Ts for the current backwater min-h . In this embodiment, once the current backwater setting water temperature Ts is determined, the hot and cold water will run for K3 minutes according to the current backwater setting water temperature Ts, except for the timing adjustment or the user-specified modification of the backwater setting water temperature Ts.
The specific implementation cases are as follows: the constant K0\K1\K2\K3 is set as: 5/4/6/30, tc of 5, th of 3, tsmax-c of 20℃and Tsmin-h of 30 ℃.
In the first embodiment, in the refrigeration mode, the backwater setting water temperature is 12 ℃, and the current ambient temperature Tw is 35 ℃. Under the starting state 9: the 30 users start the energy-saving mode, automatically store the current outdoor environment temperature of 35 ℃ as Tw1 (Tw1=35 ℃) and the current backwater set water temperature of 12 ℃ as the reference water temperature of Ts1 (Ts1=Ts=12); at 9: before 35 minutes, the user does not operate the backwater setting water temperature. When 9:35, at 9:35-9: within the period of 30, the water chiller/heater is not regulated at all, and the time for Tw and Ts to be kept unchanged is more than or equal to 5 minutes. 9: at 35, the current outdoor environment temperature Tw is detected to be 35 ℃, and Tw-Tw1=35-35=0, so that Tw-Tw1 is more than or equal to 0, and the backwater set water temperature Ts is not changed, namely, ts=Ts1=12 ℃. Because Ts is 12 ℃, the setting of Ts > 20 ℃ is not satisfied, and thus ts=12 ℃.10: before 05, the backwater setting water temperature Ts is maintained at 12 ℃ because the backwater setting water temperature is not changed by the user. 10:06, satisfy 10:06-9:35 =31 minutes, re-detect outdoor ambient temperature, assuming that the ambient temperature is 30 ℃, because Tw-tw1=30-35= -5 ℃, satisfying-20+.twtwtw1 < 0, ts=ts1+ (Tw 1-Tw)/tc=12+ (35-30)/5=13 ℃. Because Ts is 13 ℃, the setting of Ts > 20 ℃ is not satisfied, and thus ts=13℃. Every 30 minutes, the water temperature of the water back is adjusted and set by the water chiller-heater according to the control method. If the user adjusts the backwater setting water temperature, the Tw1 and the Ts1 are updated, and then the backwater setting water temperature is adjusted by the water chiller-heater according to the control method.
In the second example, in the heating mode, the water temperature is set to 45 ℃ and the current ambient temperature Tw is set to 0 ℃. Under the starting state 9: the 30 users start the energy-saving mode, automatically store the current outdoor environment temperature of 0 ℃ as Tw1 (Tw1=0 ℃), and store the current backwater set water temperature of 45 ℃ as the reference water temperature of Ts1 (Ts1=Ts=45) °c. And then the user does not operate the backwater set water temperature. At 9: before 35 minutes, the user does not operate the backwater setting water temperature. When 9:35, 9:35-9:30 =5 minutes, satisfying Tw and Ts is kept unchanged and the time is 5 minutes or more. The current outdoor ambient temperature Tw is detected to be 0 ℃, because Tw-tw1=0-0=0, tw-tw1 is satisfied to be 0 or less, and thus ts=ts1=45 ℃. Because the current backwater setting water temperature Ts is 45 ℃, and the setting of Ts < 30 ℃ is not satisfied, ts=45 ℃.10: before 05, the backwater setting water temperature Ts is kept at 45 ℃ because the backwater setting water temperature is not changed by the user. 10:06, satisfy 10:06-9:35 =31 minutes, re-detect outdoor ambient temperature, assuming that at this time the ambient temperature is 5 ℃, because Tw-tw1=5-0=5 ℃, satisfying 18+.tw-tw1+.0, ts=ts1+ (Tw 1-Tw)/tc=45+ (0-5)/3+.43.3+.43 ℃ (calculation result rounding), because Ts is 43 ℃, the setting of Ts < 30 ℃ is not satisfied, and thus ts=43 ℃. Every 30 minutes, the water temperature of the water back is adjusted and set by the water chiller-heater according to the control method. If the user adjusts the backwater setting water temperature, the Tw1 and the Ts1 are updated, and then the backwater setting water temperature is adjusted by the water chiller-heater according to the control method.
The embodiment also comprises a processor applying the operation control method of the water chiller and the water chiller, and further comprises the water chiller and the water chiller applying the operation control method of the water chiller and the water chiller.
