The water temperature control type multi-split air conditioner performs a refrigeration cycle of the water temperature control type multi-split air conditioner by using a compressor, a condenser, a throttling device, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation to refrigerate or heat an indoor space. In the water temperature control type multi-connected unit comprising the floor heating module, the indoor space is heated mainly through the floor heating module, and the water in the floor heating module absorbs the heat generated by the condenser so as to provide heat for the indoor space.
The low-temperature and low-pressure refrigerant enters the compressor, the compressor compresses the refrigerant gas in a high-temperature and high-pressure state, and the compressed refrigerant gas is discharged. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and the heat is released to the surrounding environment through the condensation process, or provides heat to the floor heating module.
The throttle device expands the high-temperature, high-pressure liquid-phase refrigerant condensed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the throttling device, and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a cooling effect by heat-exchanging with a material to be cooled using latent heat of evaporation of a refrigerant. The water temperature control type multi-split air conditioner can adjust the temperature of the indoor space throughout the cycle.
The outdoor unit of the water temperature control type multi-split air conditioner refers to a part of a refrigeration cycle including a compressor and an outdoor heat exchanger, the indoor unit of the water temperature control type multi-split air conditioner includes an indoor heat exchanger and a floor heating module, and a throttling device may be provided in the indoor unit or the outdoor unit.
In some embodiments, as shown in fig. 1, the water module for implementing water circulation with the floor heating module may be located in the outdoor unit, and is designed integrally with the outdoor unit, and is an integrated water temperature control type multi-split air conditioner.
In some embodiments, as shown in fig. 2, the water module that realizes water circulation with the floor heating module is a separate device, and is a split water temperature control type multi-split air conditioner.
The water module receives heat generated by the condenser, the heat of the condenser heats water in the water module, the water receiving the heat of the condenser circulates between the water module and the floor heating module, and the water releases heat to the indoor space through the floor heating module.
The indoor heat exchanger and the outdoor heat exchanger serve as a condenser or an evaporator. When the indoor heat exchanger is used as a condenser, the water temperature control type multi-split air conditioner is used as a heater in a heating state, and when the indoor heat exchanger is used as an evaporator, the water temperature control type multi-split air conditioner is used as a cooler in a cooling state.
As shown in fig. 1 and 2, when the user uses the floor heating mode, the user needs to set the water temperature controller side correspondingly: starting up, the ground heating mode, the target outlet water temperature, and simultaneously setting on the room temperature controllers in all rooms: starting up, a floor heating mode and a target room temperature. And after the actual unit operation is preferentially met according to the target outlet water temperature/the target room temperature, switching to a standby state. Meanwhile, the water temperature controller is usually placed in an equipment room or other places where it is not used frequently along with the installation position of the outdoor unit/water module. The user generally whole season of heating, can not change the module leaving water temperature of warming up and set for, also the temperature of setting for of the module that warms up is unchangeable promptly. However, when the temperature changes in one day or within a period of time (such as after the temperature rises, cold in spring and the like), the temperature setting of the outlet water cannot be adjusted in time by the user, and what is most important, the user cannot accurately adjust the set water temperature of the floor heating module to adapt to the change of the outdoor environment temperature, so that the multi-split air conditioner is most energy-saving and keeps the indoor environment temperature comfortable. Furthermore, even after the user has adjusted the outlet water temperature setting, there is still a problem of lag in control of the actual room temperature in consideration of the speed of water circulation.
In order to solve the problems, the set water temperature of the floor heating module is adjusted in advance according to the outdoor environment temperature at the future time, the set water temperature is adjusted in time according to the outdoor environment temperature change at the future time and is reflected on an indoor temperature control system in real time, the current temperature of the floor heating module can be matched with the outdoor environment temperature when the future time is reached, and on one hand, a user can enjoy comfortable indoor temperature without feeling, and the set water temperature does not need to be adjusted with great effort; on the other hand, the energy saving and emission reduction of the multi-split air conditioner can be realized, and the energy waste is avoided.
The following is illustrated in detail by three specific examples:
example 1
As shown in fig. 3, the water temperature control type multi-split air conditioner of the present embodiment includes a floor heating module, a floor heating module temperature obtaining module, an outdoor environment temperature obtaining module, and a control module. The following describes each module in detail:
the floor heating module is used for releasing heat to the indoor space so as to improve the indoor environment temperature.
The floor heating module temperature acquisition module is used for acquiring the current temperature of the floor heating module.
In some embodiments, the floor heating module temperature acquisition module includes a temperature sensor disposed on the floor heating module for detecting the temperature of the floor heating module, which in some embodiments is the current water temperature of the floor heating module. In some embodiments, the temperature of the incoming water to the floor heating module.
And the outdoor environment temperature acquisition module is used for acquiring the outdoor environment temperature of the future time.
In some embodiments, the outdoor ambient temperature acquisition module acquires the outdoor ambient temperature at a future time through a weather forecast.
In some embodiments, the future time is a future time T, a time point (time) determined for a future, a time point at which the current time passes the time T, for example, the time T is 2 hours, and the future time T is a time point at which the current time passes the time 2 hours.
In some embodiments, the time T may be a time T required by a preset set water temperature corresponding to an outdoor environment temperature corresponding to a time point at which the multi-split air conditioner is heated from a current temperature of the floor heating module to a future time T when the multi-split air conditioner operates in a certain state.
In some embodiments, the future Ttime may be determined experimentally in advance and stored in the storage module.
The control module is used for determining the set water temperature of the floor heating module according to the outdoor environment temperature at the future time, and controlling the multi-split air conditioner according to the set water temperature of the floor heating module and the current temperature of the floor heating module, so that the temperature of the floor heating module at the future time reaches the set water temperature of the floor heating module.
In some embodiments of the application, the outdoor environment temperature acquisition module is used for acquiring the outdoor environment temperature at the future T time, and the control module is used for determining the set water temperature of the floor heating module according to the outdoor environment temperature at the future T time. Because the floor heating temperature changes slowly, the set water temperature corresponding to the outdoor environment temperature corresponding to the time can be reached at the time T in the future, and the set water temperature is the comfortable water temperature corresponding to the outdoor environment temperature at the time T in the future.
In some embodiments of the present application, as shown in fig. 4, the control module is configured to determine the set water temperature to be Y2 when the outdoor ambient temperature at the future time T is lower than X1; the method comprises the steps of determining the set water temperature to be Y1 when the outdoor environment temperature at the future time T is higher than X2; and when the outdoor environment temperature at the future time T is between X1 and X2, determining that the set water temperature is between Y1 and Y2, wherein X1 < X2, and Y1 < Y2.
In some embodiments of the present application, the set water temperature is linearly related to the outdoor ambient temperature when the outdoor ambient temperature at time T in the future is between X1-X2.
In some embodiments of the present application, the control module is configured to re-determine the set water temperature of the floor heating module every second set time T2. The set water temperature of the floor heating module is adjusted along with the adjustment of the outdoor environment temperature, and the fixed water temperature is guaranteed to be the comfortable water temperature corresponding to the outdoor environment temperature all the time.
In some embodiments, the second set time T2 is a determined time, such as 1 hour.
In some embodiments, the second set time T2 is adjusted according to fluctuations in the outdoor ambient temperature.
In some embodiments, the second set time T2 is inversely related to the fluctuation of the outdoor ambient temperature, and the larger the fluctuation of the outdoor ambient temperature, the smaller the second set time T2, the smaller the fluctuation of the outdoor ambient temperature, and the larger the second set time T2. For example, the fluctuation of the outdoor ambient temperature is large during the early morning to midday and the midday to evening, and in this case, the second set time T2 can be shortened, and the fluctuation of the outdoor ambient temperature is small during the evening, and the second set time T2 can be lengthened. In a certain period, the set water temperature of the floor heating module does not need to be determined again when the outdoor environment temperature does not fluctuate, and the set water temperature of the floor heating module is determined again until T time before the outdoor environment temperature fluctuates, so that the calculated amount of the control module is reduced.
In some embodiments, the water temperature control type multi-connected unit is mainly used for water temperature adjustment when the air temperature changes in one day, how to adjust the set water temperature of the floor heating module in time according to the change of the outdoor environment temperature and embody the control of the indoor temperature in real time, which is the content to be solved by the embodiment.
Specifically, according to the weather forecast of the day, the water temperature of the floor heating module is adjusted at the current time according to the set water temperature determined by the outdoor environment temperature at the future T time. The specific adjusting relationship is the variable water temperature adjustment as shown in fig. 4. When the outdoor environment temperature is lower than X1, setting the water temperature Y2; when the outdoor environment temperature changes between X1 and X2, the linear adjustment is carried out before Y1 and Y2 according to the set water temperature, and the linear adjustment is carried out once every second set time T2; when the outdoor environment temperature is higher than X2, the water temperature Y1 is set.
For example, at 10 am, the outdoor ambient temperature at 12 am in the weather forecast is used, and the set water temperature is implemented in accordance with the variable water temperature control in fig. 4. Because the temperature of the floor heating changes slowly, the temperature can reach the set water temperature of 12 points corresponding to the outdoor environment temperature near 12 points, and the corresponding room temperature can be sensed, so that the room temperature reaches the comfortable temperature, and discomfort and energy waste are avoided.
As shown in fig. 5, the method for controlling a water temperature controlled multi-split air conditioner of the present embodiment includes the following steps:
and S1, starting.
S2, acquiring the set water temperature, the set room temperature, the current temperature of the floor heating module and the current room temperature.
And S3, controlling the multi-split operation.
And S4, acquiring the outdoor environment temperature at the future T time.
And S5, determining the set water temperature of the floor heating module according to the outdoor environment temperature at the future T time.
And S6, controlling the multi-split air conditioner to operate according to the redetermined set water temperature.
And S7, re-determining whether the time for setting the water temperature reaches a second set time T2, if so, entering a step S4, and otherwise, entering a step S6.
The control of the multi-split air conditioner generally includes controlling the operation of the compressor, and switching to a standby state when a set water temperature/a set room temperature is reached.
Example 2

For example, at 10 am, the set water temperature is implemented by using the outdoor ambient temperature at 12 am in the weather forecast, and corresponding to the variable water temperature control shown in fig. 4. Because the temperature of the floor heating changes slowly, the temperature can reach the set water temperature of 12 points corresponding to the outdoor environment temperature near 12 points, and the corresponding room temperature can be sensed, so that the room temperature reaches the comfortable temperature, and discomfort and energy waste are avoided.
