Problems solved by technology

[0004] When the solar air-conditioning system is equipped with the above-mentioned equipment, another problem arises: that is, when the solar device generates electric energy, if there is a possibility of demand for three different loads, how to supply the three different loads in order to achieve good performance. The effect, especially when the price of inverter power transmission has different pricing according to the time of day, and when there are different pricing for electricity from the mains at different times of the day, the situation will become more complicated. How to supply this Three different loads to achieve the best results?

Embodiment 1

[0039] see Figure 1-Figure 2 In addition to the solar power generation unit 101, the DC-DC conversion unit 102, the main control unit 103, the power storage unit 104, the inverter air-conditioning unit 106 and the DC-AC inverter unit 107, the solar air-conditioning system 10 in the present invention also includes Inverting the output unit 105 and the mains grid 108 . The inverter output unit 105 includes a DC-AC inverter unit 107 and a commercial power grid 108 . Wherein, the power storage unit 104 , the inverter air conditioner unit 106 and the DC-AC inverter unit 107 are power load units receiving current.

[0040] The solar power generation unit 101 generates electric energy, which is boosted by the DC-DC conversion unit 102 to become high-voltage direct current, and then sent to the inverter air conditioner unit 106 through the main control unit 103, and the high-voltage direct current can also be sent to the inverter output unit through the main control unit 103 105 , ...

Embodiment

[0053] see figure 1 and image 3 The difference between this embodiment and Embodiment 1 is that: when step a detects that the solar power generation unit 101 generates current, the current is supplied to the inverter air conditioner unit 106 first, then to the power storage unit 104, and to the DC- The AC inverter unit 107 supplies current.

[0054] That is, after step a, run step c110 to detect whether the variable frequency air conditioner unit is started, if it is found that the variable frequency air conditioner unit is started, then run step c111 to supply current to the variable frequency air conditioner unit, if it is found that the variable frequency air conditioner unit is not started, then run step c120.

[0055] Step c120, check whether the electric storage unit is fully charged, if it is found that the electric storage unit is not fully charged, execute step c121, supply current to the electric storage unit; if find that the electric storage unit is fully charged...

Embodiment 3

[0060] In the third embodiment of the present invention, in addition to the above-mentioned order of supplying current to the inverter air conditioner unit first, then to the power storage unit, and last to the DC-AC inverter unit, the user can The defined method determines the priority order of user tendency to meet the special requirements of different situations in different regions of users. For example, it can be used: the highest priority is to supply current to the storage unit, the second is to supply current to the inverter air conditioning unit, and the last is to supply current to the DC-AC inverter Change the order in which the units supply current. Among them, the power storage unit can not only supply the frequency conversion air conditioner unit, but also other electrical devices can get power from it, so there will be such a priority order.

[0061] Refer to the second embodiment for the rest of the undescribed parts, and will not repeat them here.

Abstract

The invention discloses a method for controlling a solar air-conditioning system. The solar air-conditioning system comprises a solar generating unit, a DC-DC conversion unit, a master control unit, an accumulation unit, a frequency conversion air-conditioning unit and a DC-AC inverting unit, wherein the accumulation unit, the frequency conversion air-conditioning unit and the DC-AC inverting unit are power load units. The control method comprises the following steps of: a, detecting whether the solar generating unit generates current, if so, executing a step b, otherwise, repeating the step a; b, reading the priority of the power load units determined in the system, and executing a step c; and c, supplying current for the power load units with requirements according to the priority of the power load units. The invention has the characteristics that: the operation is flexible, the electric energy generated in the solar air-conditioning system can be most effectively utilized, and the application range is wide.

Description

technical field [0001] The invention relates to a control method of a solar air-conditioning system, in particular to a control method of a solar air-conditioning system including multiple electric load units. Background technique [0002] In the solar air-conditioning system, there is a direct use of the electric energy generated by the solar energy to drive the air-conditioning load; but in this case, the driving electric energy can only be generated during the day, and when the air conditioner is used at night, there is a problem that the electric energy obtained during the day cannot be fully utilized. In order to solve this problem, adding energy storage devices such as batteries and supercapacitors to the solar air conditioning system can use the electric energy generated during the day for the air conditioner at night. The problem of solar energy utilization in winter or summer, but in the long transition season, because the air conditioner is not used, so a new probl...
