Fig. 1 b are the structure charts of solar airconditioning according to embodiments of the present invention, and as shown in Figure 1 b, solar cell passes through
Increasing apparatus are connected with controller, the work of controller control air-conditioning internal machine and hot-water heating system.In the present embodiment, due to too
Positive to add hot water facility in air-conditioning, the equipment can not only realize the regulation to indoor temperature, can also meet user day
Normal hot water demand, by the solar airconditioning, user saves the energy without obtaining hot water again by other approach, carries
The utilization rate of solar airconditioning high, has reached energy-saving effect.
At winter or cloudy day, sunlight is not sufficient enough, therefore the electric energy that solar cell is provided cannot meet daily demand,
In some environment, the load of solar air conditioner is larger, sunny in time, cannot still provide enough electric energy, now needs
Want extra power supply to provide the electric energy beyond solar air conditioner load capacity, it is preferable that outdoor machine of air-conditioner also connects including civil power
Mouthful, commercial power interface is powered for connecting civil power with to controller, air-conditioning internal machine and hot-water heating system.
Both can be by solar cell for supplying power, it is also possible in by the solar air conditioner of mains-supplied, for energy-conservation
Consider, it should preferably by solar cell for supplying power, it is preferable that outdoor machine of air-conditioner also includes power supply circuit, power supply circuit is connected to too
Positive energy battery and commercial power interface, in the power needed for the load that the power output of solar cell meets solar air conditioner
When, powered to solar air conditioner by solar cell, and needed for solar energy power output can not meet above-mentioned load
Power when, solar air conditioner is supplied electricity to by solar cell and city and is powered.

That is, the voltage U that solar cell is exported after being boosted through DC/DC1With civil power through the voltage U after PFC2Parallel connection, positioned at sky
Adjust the controller in outer machine by voltage control, make U1More than U2, such air-conditioning is preferentially using solar cell：When air-conditioner
When load is less than the power output of solar cell, air-conditioner is only by solar cell for supplying power；When air-conditioner load is more than the sun
During the power output of energy battery, solar cell is preferentially powered, and inadequate electric energy is provided by civil power.
In order to the use for meeting different is asked, multiple-working mode, solar air conditioner can be set to solar air conditioner
After different control instructions are received, different operations are performed, it is preferable that solar air conditioner also includes receiver, receive
Device be used for receive user setting mode of operation, wherein, mode of operation include cooling operation mode, heating operation mode, manually

The power of air-conditioner is determined that its power can be more than the output work of solar cell by the design temperature of the water temperature actual with water
Rate.
When that need not use air-conditioner, that is, when not receiving the mode of operation of user's setting, controller opens automatic heat pump
Hot-water mode, in automatic heat pump hot-water mode, the water in solar air conditioner feed-tank is heated, and makes whole system
Power is suitable with the power output of solar cell, so both takes full advantage of solar cell, and civil power need not be consumed again.
In other patterns of air-conditioner, such as blow, it is identical with general air-conditioner, repeat no more here.
The work of controller priority acccess control air-conditioning internal machine, when air-conditioning internal machine does not work, hot-water heating system works automatically, will too

（a）The power output of solar cell is detected, when solar cell power output is more than a certain setting value（It is such as fine
My god）When, if air-conditioner has been operated in certain pattern（Freeze, heat or heat-pump hot-water）, then air-conditioner is controlled to close automatic hot-water
Pattern；If air-conditioning is in holding state, air-conditioner automatic heat pump pattern is controlled, the energy that solar cell is exported
Water heating in amount feed-tank；The running frequency of compressor is controlled simultaneously, makes the power of whole air-conditioner and solar cell
Power output is suitable（Solar cell is made full use of, while not using civil power again）.
（b）When the power output of solar cell is less than a certain setting value（Such as night）：Controller closes automatic hot-water
Pattern, control selections mode of operation of the air-conditioner according to remote control（Freeze, heat, it is heat-pump hot-water, standby）.
In order to realize the purpose, solar airconditioning also includes power detection device and processor, and detection unit is used to detect
The power output of solar cell；Processor is connected to power detection device, for judge the power output of solar cell with
The magnitude relationship of predetermined power, correspondingly, controller also includes：First control unit, for the output work in solar cell
When rate is less than predetermined power, automatic heat pump hot-water mode is closed.The power very little of now solar energy output, is not enough to produce substantially
Effect.
Because the air conditioning function of solar air conditioner is prior to hot water function, therefore, typically when air conditioning function is not used
To can just use hot water function, especially automatic heat pump hot-water mode, it is preferable that also include in the controller of solar air conditioner
Second control unit, the unit is used to be more than the predetermined power, and solar energy in the power output of the solar cell
When air-conditioner is in holding state, i.e. not in cooling operation mode, heating operation mode and manual heat-pump hot-water pattern, open
Automatic heat pump hot-water mode is opened, controller can also include the 3rd control unit, and the unit is used in the solar cell
When power output is in running order more than the predetermined power, and the solar air conditioner, the automatic heat pump is closed
Hot-water mode, wherein, the working condition includes the cooling operation mode, the heating operation mode or the manual heat pump
Hot-water mode.
Air-conditioning internal machine includes evaporator, and the line temperature after evaporator is higher, and the temperature can be used in heat hot water system
Water, it is preferable that connection evaporator high temperature conduit pass through hot-water heating system.It is high by the high temperature conduit after evaporator by water tank
Warm pipeline heat release, the water heating in feed-tank, the refrigeration of air-conditioner is best under the pattern.

In no particular order, the control to the two steps can follow certain control strategy to the order of two above step.
Before being controlled to air-conditioning internal machine and hot-water heating system, can first determine by solar cell for supplying power still by the sun
Energy battery and civil power are powered jointly, it is preferable that when solar airconditioning connects solar cell and civil power, can be first determined whether too
The size of the power output of the bearing power and solar cell of positive energy air-conditioner, when the bearing power of solar air conditioner is less than
Or equal to solar cell power output when, by solar cell for supplying power；When the bearing power of solar air conditioner is more than too
During the power output of positive energy battery, bearing power is provided more than the part of power output by civil power.
Specifically, powered together with civil power after solar cell is boosted, for the consideration of energy-conservation, preferentially use solar energy
Battery.
The voltage U that solar cell is exported after being boosted through DC/DC1With civil power through the voltage U after PFC2Parallel connection, controller leads to
Overvoltage control makes U1More than U2, such air-conditioner can preferentially using solar cell power supply.When the load of air-conditioner is less than
During the power output of solar cell, air-conditioner is only by solar cell for supplying power；When air-conditioner load is more than solar cell
