[0035] The present invention provides a central management method for a multi-room air conditioner. One embodiment of the method is carried out in the following stages: current detection and monitoring stage: the current value of the power consumption is detected, and whether the detected current value exceeds the set value is monitored The current monitoring phase of the specified current value; control phase: when the current value detected by the monitoring exceeds the specified current value, the control phase of reducing the operating capacity of all air conditioners currently in operation; in the control phase, the adjustment of the operating capacity is in the detection The output current value is adjusted within the range of not exceeding the specified current value.
[0036] Another embodiment of the method is carried out in the following stages: current detection and monitoring stage: the current monitoring stage in which the current value of the power consumption is detected, and whether the detected current value exceeds the set specified current value; the control stage: When the current value detected by the monitoring exceeds the specified current value, control a part of the air conditioner to the control phase of the stop state; the control phase includes the time monitoring phase that monitors whether the air conditioning is stopped for more than the set time; when the above time monitoring phase exceeds At the set time, the air conditioner in the stopped state and the air conditioner in the operating state are repeatedly switched in the control phase.
[0037] In the control phase, when the current value detected by the monitoring does not exceed the range of the predetermined current value, a part of the air conditioner is controlled to a stop state.
[0038] The embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings:
[0039] Such as image 3 As shown, the connection structure of the multi-room air conditioner of the present invention is: multiple air conditioning groups 70#1,...70#n are set on the same power line L11, L12; the current value of the power line L11, L12 is detected It also monitors whether the transformer 50 with the set current limit value is exceeded; according to the induction value of the transformer 50, the relay 60 that supplies power to the multiple air-conditioning groups 70#1,...70#n is cut off. The prescribed current value set in the above-mentioned transformer 50 is set as: the current value when the product is damaged in an overload state.
[0040] In the connection structure of the multi-room air conditioner of the present invention, there is a central control device 80 that centrally manages a plurality of air-conditioning groups 70#1,...70#n and a signal line for transmitting signals; for identifying the input signal and Which air conditioner is associated, each air conditioner is set with a different identification code such as a different number. The above-mentioned identification code is always given at the time of signal transmission/reception between the air conditioner and the central control device.
[0041] The central control device 80 sends or receives signals between the multiple air-conditioning groups 70#1,...70#n, and receives any air-conditioning operation control signal and controls the operation of the air-conditioning. The central control device 80 can control the output level and operation sequence of each air conditioner.
[0042] The operation process of the central management method of the multi-room air conditioner is described below:
[0043] Such as Figure 4 As shown, according to the user's selection, a signal is input to all air conditioners or any air conditioner, and the input signal is transmitted to the central control device 80 through a signal line. The central control device 80 interprets the signal input from the signal line, and confirms which air conditioner is transmitted from, and what kind of control signal is required. The central control device 80 permits the operation of the air conditioner that needs to be operated through signal transmission/reception. The air conditioner that is permitted to operate under the control of the central control device 80 is operated by introducing electric power through the power lines L11 and L12.
[0044] The above-mentioned power lines L11 and L12 are power lines of all air conditioners connected to the same place. That is, the multi-room air conditioner of the present invention introduces power through the same power lines L11 and L12. The electricity input from the power lines L11 and L12 is supplied to the air conditioner that is permitted to operate through the relay 60.
[0045] The transformer 50 detects the current values on the power lines L11 and L12. The current values of the power lines L11 and L12 are proportional to the load of the air conditioner in operation. Therefore, the transformer 50 detects the current values on the power lines L11 and L12, and monitors whether the current value exceeds the set specified current value, that is, the 200th stage;
[0046] When the monitoring detects that the current value does not exceed the set predetermined current value in the 200th stage, the central control device 80 continues to maintain the existing control state. Of course, at this time, only the air conditioner that is driven by the user is operated.
[0047]During the above-mentioned operation process, the transformer 50 continues to monitor whether the supply current exceeds the prescribed current value. The central control device 80 executes the central management system of the air-conditioning at the starting point that exceeds the predetermined current value. That is, the central control device 80 requires that when the load of the plurality of air conditioners in the operating state exceeds a predetermined current value, the current power usage state is considered to control the operation or output level of the plurality of air conditioners.
[0048] Generally, the power consumption of air conditioners is concentrated in summer, and the highest temperature of the day is between 2 and 4, which is the peak of power consumption. The number of people using the air conditioner increases the power consumption. According to the central management system of the central control device 80 of the present invention, the control and management can be conveniently performed.
[0049] First, the central control device 80 needs to evenly distribute the power usage to all air conditioners in operation. The 210th stage is one of the methods, that is, whether to control the sequence. The situation of sequence control should be based on the user's choice. According to the sequence control of the 210th stage, all the air conditioners are used at the same time, and the operation capacity of the air conditioners is controlled to decrease from the current level.
[0050] If, in the above-mentioned 210th stage, the control is in order, in the 230th stage, the air-conditioning operation capability is reduced. The operating capacity (ie, output level) of all air conditioners in operation is reduced by one stage for control, so the power used does not exceed the range of the above-mentioned prescribed current value. Therefore, the operating state of all air conditioners is adjusted according to the operating capacity of the air conditioner in the 230th stage. Starting from the point where the maximum power is consumed, the current value detected by the transformer 50 is reached to operate within the specified current range set in the 200th stage.
[0051] If the sequence control is not possible in the above-mentioned 210th stage, the central control device 80 stops a part of all the air conditioners in the operating state within a predetermined time, so that the other air conditioners continue to operate, that is, the 220th stage. In the above-mentioned 220th stage, it is better to control only one air conditioner in the stopped state among all the air conditioners in the operating state.
[0052] In the above-mentioned 220th stage, the air conditioner in the stagnant state has passed the 240th stage, that is, whether a certain period of time has passed. If it exceeds the set certain time, the control is resumed to the operating state. At this time, the other air-conditioning control is in the 250th stage, that is, stopping the next air-conditioning is the stop state. In the control phase, the air conditioner in the stopped state and the air conditioner in the operating state are repeatedly switched.
[0053] That is, from the 220th stage to the 250th stage, the operating capabilities (output levels) of all air conditioners in the operating state are maintained at the current state, and the operating sequence (or the stopping sequence) is variably controlled.
[0054] With this control, the user of the multi-room air conditioner can obtain the desired cooling/heating effect under the condition that the power consumption does not exceed the range according to the load of the air conditioner.
[0055] The predetermined current described in the 200th stage of the present invention is set to a current lower than the predetermined current value set in the 100th stage. This is because the existing prescribed current is set in a range where it is impossible to continue driving; on the contrary, the prescribed current design of the present invention can be driven within its range. What's more important is that the calculation of electricity bills is based on peak electricity, so the lower the current setting in the 200th phase, the lower the electricity bill will become.
[0056] In summary, the central management method of the multi-room air conditioner of the present invention is characterized in that when multiple air conditioners are used at the same time, the central control device 80 compulsively controls the air conditioner in the range below the peak power, and the air conditioner can be in operation. In particular, the present invention reduces the output level of the air conditioner or repeatedly controls a part of the air conditioner to be stopped for a certain period of time, thereby limiting the power consumption.
[0057] The central management method of the multi-room air conditioner of the present invention is not limited to the above-mentioned content, and the scope of power of the present invention should be based on the scope of patent protection.
