Abstract

PROBLEM TO BE SOLVED: To restrict a consumption of commercial electrical power small even if an operation is performed for a long period of time by a method wherein there is provided a restriction control section for correcting a signal for adjusting the number of rotation of a compressor so as not to cause a second electrical power detected value to exceed a detected value of a first electrical power sensing section. SOLUTION: Solar light absorbed at a solar panel 310 is converted into an electrical energy, supplied to an inverter circuit 312 and this DC power source is converted into an AC power source. At this time, a signal is transferred from a micro-computer 320 to the inverter circuit 312 and converted into a power source (a voltage and a frequency) suitable for that region. In this case, an electrical generated power caused by a commercial power source supplying device SOL is detected by a generated power sensing sensor 358 and then an air conditioner operation capability is controlled through a comparison of these values. Accordingly, if a part of the power is controlled so as to be supplied by the generated electrical power, it is possible to perform a continuous operation for a long period of time under a consumption of a less amount of commercial electrical power.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioning system having a commercial power supply function having a function of generating power using sunlight as an energy source and supplying the generated power to a commercial power supply.

[0002]

2. Description of the Related Art A conventional air conditioner exchanges heat with a refrigerant so that, for example, a heating mode, a cooling mode, a dry mode, a set temperature and a room temperature at the start of operation are set. It is possible to operate in each mode such as automatic operation mode that automatically selects either heating mode or cooling mode by comparison, and change these modes etc. with the attached remote control, and indoors Air conditioning is available.

At present, a so-called solar air conditioner utilizing solar energy has been developed as a power supply for the air conditioner (for example, Japanese Patent Application Laid-Open No. 6-74522).
No.). In this solar air conditioner, electric power generated based on sunlight absorbed by a solar panel is directly used as a power supply of an air conditioner. In addition, in this air conditioner, a general commercial power supply is used in combination so as to be independent of the weather, and when the amount of power generated by sunlight is small, the shortage is obtained from the general commercial power supply. .

[0004] However, in the solar air conditioner having the above configuration, the power generated by sunlight can be used only by the air conditioner. In addition, there has been a problem that a sufficient air-conditioning operation cannot be performed unless a general commercial power supply is used.

[0005] For this reason, for example, when there is a room in which the air-conditioning state is always kept at a predetermined temperature or humidity, the power consumption of the commercial power supply changes depending on the weather and time, and the electricity cost cannot be predicted, and unexpected expenses are incurred. It may be. Therefore, a solar air conditioner that can be covered only by solar energy may be used. However, to achieve this, a solar panel having a very large area is required, which is not practical.

[0006] As a related technique, a commercial power supply system has been developed which supplies electric power generated using sunlight as an energy source to an indoor commercial power supply wiring and a surplus power to a commercial power supply. The generated power is once returned to a commercial power source to offset the power fee and reduce the cost due to power consumption.

[0007] In view of the above facts, the present invention provides an air conditioner with a commercial power supply function that can slightly suppress the consumption of commercial power by installing solar panels within a practical range, even if the operation is continued for a long time. The purpose is to get a chance.

Here, the first power detector detects the amount of power generated by using sunlight as an energy source to be supplied to a commercial power supply (hereinafter referred to as “generated power”). Detects the power consumed by the air conditioner or the power consumed by the compressor (hereinafter referred to as power consumption).

The detected values of the first and second detectors are compared, and the rotational speed of the compressor is corrected so that the power consumption of the compressor does not exceed the power generated by the solar panel. That is, the operation of the compressor is set to an operation corresponding to the amount of power generated by the solar panel. That is, the air conditioner is operated with a high capacity when the generated power is close to the maximum, such as when the weather is fine, and the capacity of the air conditioner is reduced when the generated power does not increase, such as when it is rainy.

It is suitable for a room or the like where air-conditioning is desired to be continued for a long time and air-conditioned. Even in continuous operation, the power consumption can be entirely covered by the generated power, and the electricity cost can be reduced.

In addition, since it is not necessary to increase the size of solar equipment (for example, enlargement of the area of the solar panel) for obtaining the full capacity of the air conditioner, the equipment is complicated because it is controlled by the operating capacity of the air conditioner itself. It does not change.

It should be noted that whether or not to perform the above-described driving capability control may be selected by a switch operation.

Solar panel 310 that absorbs sunlight
Is mounted on a roof or the like with a plurality of modules set in a frame. The energy absorbed by the solar panel 310 is supplied to the inverter circuit 312. That is, the electric power generated by the solar panel 310 is DC, and is converted into AC by the inverter circuit 312.

The converted AC power is supplied to an insulation transformer 31.
4 and is adjusted to a power supply frequency similar to that of a commercial power supply (for example, a sine wave of 200 V, 50 Hz). The output side of the insulating transformer 314 is connected to one of the breakers 350 provided for each predetermined block via a disconnecting conductor 316 and to a disconnection switch 354 for disconnecting from the outside via a main breaker 352. ing. This off-switch 654 is connected to a transformer 318 at the end of a power system installed on a telephone pole or the like. The primary side of the transformer 318 has a predetermined voltage (for example, a single-phase 200V) from a substation of a power company.
Power is supplied.

In the transformer 318, the voltage on the primary side is reduced to a commercial voltage (for example, 200 V) (secondary side voltage).

Therefore, normally, as shown in the direction of arrow A in FIG. 1, power is supplied from the secondary side of the transformer 318 to ordinary households.

On the other hand, the electric power generated by the solar panel 310 is supplied to the secondary side of the transformer 318 as shown in the direction of arrow B in FIG. 1, and the power capacity of the transformer 318 is increased. I have.

The microcomputer 320 for controlling the inverter circuit 312 receives a voltage input by A / D and a current by CT to input the solar panel 31.
Inverter circuit 31 so that 0 operates at the optimum operating point.
2 is controlled.

The microcomputer 320
, The opening and closing of the paralleling conductor 316 provided between the transformer 314 and the transformer 318 is also controlled. The parallel-off conductor 316 has a switching function of supplying the power generated by the solar panel 310 to the transformer 318 or interrupting the supply.
Off is controlled.

Further, the microcomputer 320 calculates the electric power passing through the insulating transformer 314, and transmits this value to the outdoor unit of the air conditioner via the signal line S by communication.

As described above, the microcomputer 102F in the outdoor unit 12 of the air conditioner A / C (see FIG. 5)
And the microcomputer 320 in the commercial power supply unit SOL are separately mounted.
By installing such an air conditioner at home or the like, the air conditioner itself receives electric power from a commercial power supply as usual, so that there is no change in power consumption. However, regardless of the operation or non-operation of the air conditioner, the commercial power supply unit SOL always returns the power generated by sunlight to the commercial power side (since the power is sold), so that it is used in the entire household. The returned electric power is deducted from the used electric power, thereby contributing to energy saving.

Here, in the present embodiment, a generated power detection unit (calculated from voltage and current) for detecting the amount of generated power generated by solar panel 310 and converted to commercial power, and the power consumption of the air conditioner And an air conditioner power consumption detection sensor 358 (calculated from the voltage and the current value by CT), which detect the power consumption of the microcomputer and the microcomputer 1 of the control board 320, respectively.
02F. Microcomputer 320
The detected value of the generated power detection sensor 356 input to the microcomputer is transmitted to the microcomputer 102F on the air conditioner side by communication, and the microcomputer 102F compares these detected values, and when the switch (solar keep switch) is valid, the microcomputer 102F Is used to control the driving ability. That is, the operating capacity of the air conditioner is controlled so that the power consumption of the air conditioner does not exceed the generated power, thereby canceling the power supply and consumption.

The operation of the embodiment of the present invention will be described below. First, a normal operation in the air conditioner unit A / C will be described.

When the remote controller 14 is operated in the operation stop state and the output operation signal is received by the receiving circuit 76A, the code of the received operation signal is analyzed.

It is determined whether the result of the analysis is a power-on command or a timer setting command. That is, the remote controller 14
When the power is turned off, the operation signal operated by is a signal that is canceled, for example, a temperature setting, an air volume setting, and the like.
In this case, it does not accept and waits in the receiving state.

Here, when recognizing that the command is a timer setting command, the operator of the remote controller 14 sets a timer so as to operate the air conditioner after a predetermined time. For example, 2
After an hour, the air conditioner is set to operate, and the remote controller 14 is operated to output an operation signal. This allows
A timer (on time) is set. With this setting, the operation can be automatically started after two hours.

On the other hand, when the power-on command is recognized, the operation is started in the setting mode before the previous operation was stopped.

Thereafter, when an operation signal from the remote controller 14 is received, the code of the received operation signal is analyzed, and whether or not the analyzed content is a power-off command and whether or not the air volume is set (changed) is determined. Then, it is determined whether or not the temperature is set (changed) or not, and whether or not the timer is set (changed). The item corresponding to the analysis content is selected to stop the operation or change the setting of the operation mode.

In the air conditioner section A / C, the indoor unit 10
Microcomputer 72C calculates the amount of increase or decrease of the required air capacity with respect to the current air conditioning capacity by comparing the change in the difference between the set temperature / set humidity and the room temperature / humidity of the conditioned room with the fuzzy calculation.

The amount of increase or decrease is represented by the number of revolutions of the compressor 106. When the compressor 106 is a drive source of an AC motor, the frequency is represented by a frequency.

This increase / decrease amount is sent to the microcomputer 102F of the outdoor unit 12 via a signal line connecting the indoor unit 10 and the outdoor unit 12.

The microcomputer 102F of the outdoor unit 12
The current frequency (the frequency of the AC power supplied to the compressor 106) is corrected according to the increase or decrease of the frequency, and the compressor is operated at a new frequency. The start / stop of the compressor 106 follows another process.

The microcomputer 102 of the outdoor unit 12
F constantly samples the current consumed (supplied) by the compressor 106, and further increases the frequency so that this current does not exceed a predetermined value, for example, the capacity of a breaker in a general household (ie, 20A, etc.). to correct.

More specifically, when the current exceeds a predetermined value -2A, the correction to increase the frequency is prohibited, and when the current exceeds the predetermined value -1A, the frequency is lowered at a rate of 1 Hz / sec. This lowering correction is performed when the current is a predetermined value-
Continue to 3A.

Next, the operation of the commercial power supply unit SOL will be described. During normal times, that is, when power is supplied to the transformer 318, the parallel-off conductor 316 is in a closed state.

The sunlight absorbed by the solar panel 310 is converted into electric energy, and is converted into electric energy.
2 is supplied. The power at this time is DC, and the inverter circuit 312 converts the DC power into an AC power. At this time, the microcomputer 320 outputs the power supply voltage and the frequency of the region from the inverter circuit 31 to which the frequency enters.
2 and converted to power (voltage / frequency) appropriate for the area. The frequency of the area can be obtained by analyzing a voltage waveform applied to the A / D terminal via a breaker before starting power generation.

The waveform converted by the inverter circuit 312 is converted into a sine wave by the insulating transformer 314, and when the parallel-off conductor 316 is in the closed state, it is connected to the secondary side of the transformer 318 as shown by the arrow B in FIG. Can be supplied.

In the present embodiment, the power generated by the commercial power supply unit SOL is
At 56, the power consumption of the air conditioner unit A / C is detected by the power consumption detection sensor 358, and the air conditioner operating capacity is controlled by comparing these.

That is, if there is a room or the like where the air conditioner is always turned on and the air conditioning is desired, it is not known how much the power consumption will be, and it is necessary to predict the electricity cost to be offset by the generated power. Can not. Therefore, in rainy weather or at night, it is necessary to weaken or stop the driving state to adjust the power consumption. However, in the present embodiment, if the solar keep switch is enabled, the SO
Since the value of the generated power transmitted from L is replaced with the above-mentioned predetermined value for current control or a value 1A lower than this value, the operating capacity of the air conditioner is controlled according to the generated power. Therefore, the air conditioner is always operated within the range of the generated power. In other words, when the sunlight is sufficiently absorbed and the generated power is sufficiently large, such as in fine weather, the generated power is not exceeded even if the air conditioner is operated at full capacity. Next, when the generated power decreases in rainy weather or the like, the operating capacity of the air conditioner is reduced, and control is performed so that power consumption does not exceed the reduced generated power.

By performing such control, the solar panel 31 is operated in order to always operate the air conditioner at full capacity.
The electric power consumed by the air conditioner can be entirely covered by the generated power without performing impractical facilities such as increasing the size of the zero, and the electricity bill is unnecessary.

In the present embodiment, the power consumption is controlled so as not to exceed the power generation. However, the power consumption is not completely covered by the power generation, but a predetermined part (for example, 80%). Is controlled so as to be covered by the generated power, it is possible to perform continuous operation for a long time with a small consumption of commercial power (which can be predicted by calculation) without extremely lowering the operating capacity.

The driving capability control may be performed at all times, or may be selectively performed by operating a switch as necessary.
