It should be noted that, in the method of this embodiment, the heating requirements of the multi-split air conditioner include: the air conditioner has a plurality of heating requirements, namely 1, the air conditioner internal mechanism heating and the hydraulic module heating water, 2, the hydraulic module heating water and the hydraulic module heating floor heating; 3. the indoor heating and hydraulic module of the air conditioner performs floor heating; 4. four scenes of heating by an air conditioner internal mechanism, heating water by a hydraulic module and heating by a hydraulic module.
In a specific implementation, if the multi-split air conditioner has the energy requirement of heating water by the internal air conditioning mechanism heating and hydraulic module, because the water quantity of the water tank is less and the temperature is raised faster when the user faces the internal air conditioning mechanism heating and hydraulic module heating water, and the user needs to output hot water in a short time, the priority of the hydraulic module is higher than that of the internal air conditioner.
If the multi-split air conditioner has the energy requirements of heating water by the hydraulic module and heating by the hydraulic module, the two requirements are the priority of the hydraulic module for heating by running, the heating of the floor heating is slower, the heating of the water tank is faster by controlling the priority of the hydraulic module and the three-way valve in the hydraulic module, the three-way valve is preferentially communicated with a first waterway where the water tank is located, and after the water tank reaches the temperature, the three-way valve is communicated with a second waterway where a heating coil is located, so that the opening of a second throttling element is enlarged.
If the multi-split air conditioner has the energy requirements of heating in the air conditioner and heating by the hydraulic module, the two are used for heating, the heating of the floor heating is slower, and the temperature of the air conditioner is relatively faster, so that the priority of the air conditioner is higher than that of the hydraulic module.
If the energy requirements of heating by the air conditioner internal mechanism, heating water by the hydraulic module and heating by the ground heating by the hydraulic module of the multi-split air conditioner are met, the water tank can be firstly heated, the water tank is switched to the air conditioner internal mechanism for heating after reaching the temperature, and finally the ground heating is performed, namely, the control priority of the hydraulic module is firstly greater than that of the air conditioner internal machine, and then the control priority of the hydraulic module is smaller than that of the air conditioner internal machine.
Step S20: and acquiring the equipment temperature of the air conditioner and the outdoor environment temperature of the area where the external unit is located.
It can be understood that the equipment temperature of the air conditioner specifically comprises the exhaust temperature at the outlet of the compressor of the external machine and the coil temperature or the middle temperature of the indoor heat exchanger, and meanwhile, if a plurality of connected internal machines exist or a plurality of indoor heat exchangers exist in a single internal machine, the coil temperature average value of each indoor heat exchanger can be taken as the coil temperature of the indoor heat exchanger; the outdoor environment temperature of the area where the outdoor unit is located can be the temperature collected through a temperature sensor or a temperature sensing bulb arranged on a shell of the outdoor unit, and also can be the temperature collected by the temperature sensing bulb at the position of the outdoor heat exchanger in the outdoor unit, wherein if a plurality of outdoor heat exchangers exist in the outdoor unit, the average value of the temperatures collected by the temperature sensing bulbs at the positions of the outdoor heat exchangers can be taken as the outdoor environment temperature, so that the influence of the outdoor environment temperature on the control scheme in the embodiment is reduced.
Step S30: and determining opening variation values of all throttling elements according to the equipment temperature of the air conditioner, the outdoor environment temperature and the control priority.
It can be understood that when the priority of the air conditioner indoor unit is higher, the first throttling element between the air conditioner indoor unit and the outer machine can be opened as much as possible on the premise of not affecting the reliability of the whole machine, so that the refrigerant is distributed to the air conditioner indoor unit more, and meanwhile, the second throttling element between the hydraulic module and the outer machine can be controlled according to the temperature average value of the coil pipe of the indoor heat exchanger.
When the control priority of the hydraulic module is higher, the opening change corresponding to the first throttling element between the air conditioner inner machine and the air conditioner outer machine is determined by the exhaust temperature of the compressor; the second throttling element between the hydraulic module and the external machine takes a fixed opening according to the outdoor environment temperature.
Step S40: and adjusting the opening of each throttling element according to the opening variation value.
It should be understood that when the control priority of the air conditioner indoor unit is higher than the control priority of the hydraulic module, the opening degree of the first throttling element between the air conditioner indoor unit and the outer machine can be increased, and the opening degree of the first throttling element between the air conditioner indoor unit and the outer machine and the second throttling element between the hydraulic module and the outer machine can be increased, but the opening degree of the first throttling element is adjusted more so as to increase the amount of refrigerant flowing into the air conditioner indoor unit and accelerate the temperature rising efficiency of the air conditioner indoor unit.
Similarly, when the control priority of the air conditioner internal unit is lower than that of the hydraulic module, the opening degree of the second throttling element between the hydraulic module and the external unit can be increased, and the opening degree of the first throttling element between the air conditioner internal unit and the external unit and the opening degree of the second throttling element between the hydraulic module and the external unit can be increased, but the opening degree of the second throttling element is adjusted more so as to increase the refrigerant quantity flowing into the hydraulic module and accelerate the temperature rise efficiency of the waterway in the hydraulic module.
The invention judges the current energy demand type of the multi-split air conditioner, further determines the control priority of the air conditioner internal unit and the hydraulic module, so as to avoid the technical problems that the external unit needs to provide more refrigerants at the same time, achieve higher heating effect, reduce the load of the external unit at the same time, calculate the opening change value of each throttling element according to the control priority and combining the equipment temperature and the outdoor environment temperature of the air conditioner, thereby realizing accurate refrigerant distribution, improving the configuration rate of the external unit, avoiding the technical problems that the multi-split air conditioner in the prior art has multiple energy demands at the same time, has higher configuration rate of the air conditioner external unit, is difficult to meet the use demands of users, and improves the heating efficiency.
Referring to fig. 4, fig. 4 is a flowchart illustrating a control method of an air conditioner according to a second embodiment of the present invention.
Based on the first embodiment, in this embodiment, the step S30 includes:
step S301: and when the priority of the hydraulic module is higher than that of the air conditioner indoor unit, acquiring the water outlet temperature of the water tank.
When the priority of the hydraulic module is higher than that of the air conditioner internal unit, the water heating requirement of the hydraulic module is met, whether the water path temperature rise is excessive or not can be judged according to the water outlet temperature, if the water path temperature rise of the hydraulic module is excessive, the air conditioner can be controlled to only operate the hydraulic module for heating, the air conditioner internal unit heating operation is closed, and the air conditioner internal unit heating operation is particularly characterized in that a first throttling element between the external unit and the air conditioner internal unit is closed, and a second throttling element between the external unit and the hydraulic module is opened; if the waterway temperature rise of the hydraulic module is not large, the air conditioner indoor unit can operate, and the opening of the first throttling element is controlled normally.
Step S302: and when the outlet water temperature is higher than a preset first temperature threshold value, determining a first opening degree change value of the first throttling element according to the equipment temperature.
It should be noted that the range of the preset temperature threshold is 30-45 ℃, and the embodiment is illustrated by taking 40 ℃ as an example.
When the outlet water temperature is higher than 40 ℃, the air conditioner can normally operate, and the opening change of the first throttling element is obtained by calculating the exhaust temperature of the outer compressor; when the temperature of the discharged water is less than 40 ℃, the first throttling element between the outer machine and the air conditioner inner machine is closed, and the air conditioner can only operate by the water conservancy module without identification.
Further, the determining the first opening degree variation value of the first throttling element according to the equipment temperature includes:
acquiring the current exhaust temperature, the target exhaust temperature and the first exhaust temperature and the second exhaust temperature of the compressor in a history adjustment period, wherein the first exhaust temperature is the exhaust temperature of the previous adjustment period, and the second exhaust temperature is the exhaust temperature of the previous adjustment period;
and calculating a first opening degree variation value of the first throttling element according to the first exhaust temperature, the second exhaust temperature, the current exhaust temperature, the target exhaust temperature and a preset regulating parameter.
In this embodiment, in order to precisely control the opening of the throttling element, a PID algorithm is used in combination with the exhaust temperature of the compressor to control the opening of the first throttling element corresponding to the air conditioner, which is specifically implemented by comprehensively calculating the current exhaust temperature, the first exhaust temperature and the second exhaust temperature of the compressor in a history adjustment period as a proportional value, an integral value and a derivative value, respectively, to obtain an opening variation value of the first throttling element, where the adjustment period ranges from 20s to 180s, and the embodiment uses 45s as an adjustment period.
