Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be described in detail below. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without making any creative effort, shall fall within the protection scope of the present application.
Examples
Referring to fig. 1, fig. 1 is a schematic structural diagram of an air conditioning system according to an embodiment of the present application.
As shown in fig. 1, the present embodiment provides an air conditioning system, including:
a control device 101, an absorption air conditioning unit 102, a compression air conditioning unit 103, a photo-thermal power generation system 104, and a photovoltaic power generation system 105, which are connected to the control device 101, respectively;
the photo-thermal power generation system 104 is used for generating electric energy and steam and supplying the electric energy and the steam to the absorption air conditioning unit 102 so as to enable the absorption air conditioning unit 102 to work;
the photovoltaic power generation system 105 is used for generating electric energy and supplying the electric energy to the compression type air conditioning unit 103 so as to enable the compression type air conditioning unit 103 to work;
a control device 101 for controlling to turn on the absorption type air conditioning unit 102 if the pressure of the steam that can be generated by the photo-thermal power generation system 104 is greater than or equal to a first pressure; and if the pressure of the steam which can be generated by the photo-thermal power generation system 104 is less than the first pressure, controlling to start the compression type air conditioning unit 103.
The absorption air conditioning unit 102 is mainly an air conditioning unit that absorbs heat to operate, such as a lithium bromide unit. The photo-thermal power generation system 104 can convert light energy into heat energy by using the high temperature of solar energy and generate power by using the heat energy, so that heat energy (i.e., steam) and electric energy required by the lithium bromide unit can be provided. The absorption air conditioning unit 102 may operate on the steam and the electric power provided by the photo-thermal power generation system 104 to absorb heat of the steam for cooling or heating.
The compression type air conditioning unit 103 is mainly an air conditioning unit in which a compressor compresses steam by electric energy to work, such as a photovoltaic direct-current variable frequency centrifuge. The photovoltaic power generation system 105 is a power generation system that directly converts light energy into electric energy without a thermal process, and thus, can provide electric energy required by the compression type air conditioning unit 103 to perform cooling or heating.
The control device 101 may be an electric control cabinet or the like. The control device 101 may activate the photo-thermal power generation system 104 to generate electrical energy and steam, and activate the photovoltaic power generation system 105 to generate electrical energy.
The first pressure may be set according to actual needs, for example, the first pressure may be 0.5-0.9Mpa, and preferably 0.8Mpa, in the case of lithium bromide unit refrigeration.
Because the air conditioning system is provided with two air conditioning units, namely an absorption air conditioning unit 102 and a compression air conditioning unit 103, and the photo-thermal power generation system 104 corresponding to the absorption air conditioning unit 102 and the photovoltaic power generation system 105 corresponding to the compression air conditioning unit 103, in practical application, if the pressure of steam which can be generated by the photo-thermal power generation system 104 is greater than or equal to a first pressure, which indicates that the absorption air conditioning unit 102 can work by the photo-thermal power generation system 104 at the moment, the absorption air conditioning unit 102 is started, and if the pressure of steam which can be generated by the photo-thermal power generation system 104 is less than the first pressure, which indicates that the absorption air conditioning unit 102 cannot work by the photo-thermal power generation system 104 due to insufficient illumination at the moment, the compression air conditioning unit 103 is started, that is, the absorption air conditioning unit 102 is preferentially started, and because the absorption air conditioning unit 102 consumes less electric energy compared with the compression air conditioning, therefore, the energy-saving requirement can be met, when the illumination is insufficient, the absorption air conditioning unit 102 can not normally work, the compression air conditioning unit 103 is opened again, the photovoltaic power generation system 105 corresponding to the compression air conditioning unit 103 is different from the photo-thermal power generation system 104, the limitation of the pressure of steam is avoided, the stability of the air conditioning system can be guaranteed, and therefore the energy conservation and the stability of the air conditioning system are guaranteed integrally, in addition, the photovoltaic power generation system 105 and the photo-thermal power generation system 104 are both the photoelectric technology utilizing solar energy, and the energy-saving requirement is further met.
Because the capacity of the absorption air conditioning unit 102 is limited, if the output power of the absorption air conditioning unit 102 has reached the maximum capacity, that is, the amount of cooling or heating that can be output has reached the maximum, and the demand of the user still cannot be met, the compensation of the amount of cooling or heating can be performed by the compression air conditioning unit 103, therefore, in some embodiments, the control device 101 is further configured to determine whether the power of the absorption air conditioning unit 102 can meet the demand after controlling to turn on the absorption air conditioning unit 102, and if the power cannot meet the demand, control to turn on the compression air conditioning unit 103. Therefore, the power supplement of the compression type air conditioning unit 103 can meet the requirements of refrigeration or heating of users, and the adaptability and the comfort of the air conditioning system are improved.
In a state where the absorption air conditioning unit 102 is turned on, if the illumination is gradually insufficient, the electric energy that the photo-thermal power generation system 104 can provide is gradually reduced, and the photovoltaic power generation system 105 may also be used to supplement the electric energy, based on this, in some embodiments, as shown in fig. 2, the photovoltaic power generation system 105 is further connected to the photo-thermal power generation system 104, and the control device 101 is further configured to determine whether the pressure of the steam generated by the photo-thermal power generation system 104 is greater than the first pressure and less than the second pressure after the absorption air conditioning unit 102 is turned on, and if so, control the photovoltaic power generation system 105 to supplement the electric energy for the photo-thermal power generation system 104.
Wherein, the second pressure is that the pressure of steam drops to a value that is close to first pressure, specifically can set up according to actual need, and when the pressure of steam closes to first pressure, can supply the electric energy as early as possible, guarantees that light and heat power generation system 104 can continuously produce the steam of sufficient pressure to guarantee that absorption air conditioning unit 102 can continuous work, and then guarantee air conditioning system's energy-conservation, stability.
In some embodiments, as shown in fig. 2, the photovoltaic power generation system 105 is also used to connect to an external grid 6; correspondingly, the control device 101 is further configured to monitor the electric energy generated by the photovoltaic power generation system 105 and the required electric energy, compare the electric energy generated by the photovoltaic power generation system 105 with the required electric energy, indicate that there is surplus electric energy if the electric energy generated by the photovoltaic power generation system 105 is greater than the required electric energy, control the photovoltaic power generation system 105 to transmit electric energy to the external grid 6, and indicate that the electric energy is insufficient if the electric energy generated by the photovoltaic power generation system 105 is less than the electric energy required by the compression type air conditioning unit 103, control the photovoltaic power generation system 105 to receive the electric energy supplemented by the external grid 6. So, if air conditioning system self can't satisfy the electric energy demand when, lead to outer net 6 and supply the electric energy, can guarantee air conditioning system's stability to can also be when the electric energy is sufficient to outer net 6 feed.
If the photovoltaic power generation system 105 only provides power for the compression air conditioning unit 103, the required power is the power required by the compression air conditioning unit 103.
If the photovoltaic power generation system 105 provides electric energy for the compression type air conditioning unit 103 and supplements the electric energy for the photo-thermal power generation system 104, the required electric energy is the sum of the electric energy required by the compression type air conditioning unit 103 and the electric energy supplemented for the photo-thermal power generation system 104.
Of course, if the photovoltaic power generation system 105 does not provide power to the air conditioning unit, the power demand is zero.
In some embodiments, the control device 101 is specifically configured to periodically detect the power generated by the photovoltaic power generation system 105 and the power required by the photovoltaic power generation system 105 when monitoring the power generated by the photovoltaic power generation system 105 and the power required. Thus, by periodic detection, real-time monitoring of the electrical energy can be achieved. The period of the detection can be set according to actual needs, for example, 2 hours is set as one period.
Referring to fig. 3, fig. 3 is a flowchart of a control method of an air conditioning system according to another embodiment of the present application.
As shown in fig. 3, the present embodiment provides a control method of an air conditioning system, which is applied to the air conditioning system according to any of the above embodiments, and the control method of the air conditioning system includes the following steps:
and step 33, if the pressure of the steam which can be generated by the photo-thermal power generation system is smaller than the first pressure, controlling to start the compression type air conditioning unit.
Optionally, the method further includes:
judging whether the power of the absorption type air conditioning unit can meet the requirement or not;
if the requirement cannot be met, the compression type air conditioning unit is controlled to be started.
