Description
Technical Field
The utility model relates to a power saving device, in particular to communication computer lab air conditioner power saving device.
Background
In a communication room, an air conditioner is an important device for ensuring the constant temperature of the communication room. Generally, the main factors affecting the power consumption of an air conditioner include: the fluctuation of outdoor air temperature is large (-20 ℃ to +40 ℃); the mounting position of the air conditioner is too high or too low; too much or too little heat load; and non-uniformity of indoor temperature.
The most widely used automatic regulating system of the existing air conditioner is a constant value regulating method, a negative temperature coefficient thermistor is adopted to sense the room temperature, the design control precision is +/-0.5 ℃, and the instantaneous deviation is +/-1 ℃ due to thermal inertia. For example, if the set temperature is 23 ℃ and the design room temperature control accuracy is ± 0.5 ℃, when the air conditioner senses that the indoor temperature rises to over 23.5 ℃, the air conditioner compressor operates (the room temperature continues to rise to 24 ℃ due to thermal inertia); when the air conditioner senses that the indoor temperature is reduced to 22.5 ℃, the air conditioner compressor stops running (the room temperature is continuously reduced to 22 ℃ due to thermal inertia); and the process is circulated.
In the process of implementing the invention, the inventor finds that the prior air conditioner operation mode has the following defects:
the limit temperature which can be reached in the use environment cannot be automatically judged according to the outdoor temperature, the indoor heat load and the set temperature value, so that the temperature sensing head of the air conditioner cannot sense the set temperature value (namely the room temperature cannot reach the set temperature value) when the load is high, the air conditioner compressor can continuously operate, the power consumption of the air conditioner is large, and the service life of the air conditioner can be shortened due to the continuous operation of the compressor. For example, when the outdoor temperature is above 32 ℃ and the set temperature is below 25 ℃, the air conditioner may be in such a high load state;
in addition, the existing air conditioner can not adjust the temperature control precision according to the actual requirement, and the compressor can be frequently started and stopped under the condition of low load, and the starting current of the compressor is 3-5 times of the running current, so that the starting and stopping loss can be increased. For example, when the outdoor temperature is 32 ℃ or lower and the set temperature is 25 ℃ or higher, the air conditioner is in such a low load state.
Because of the special requirements of the air conditioner operation of a communication room, which is generally turned on for a long time (for example, twenty-four hours of operation per day), the existing air conditioner operation mode makes the air conditioner of the communication room very power consuming and reduces the service life of the air conditioner.

The utility model discloses a communication computer lab air conditioner power saving device (hereinafter abbreviated as power saving device) includes: the device comprises a main control unit, a power supply conversion unit, at least one compensation unit (two are drawn in the figure), at least one temperature sensing head (two are drawn in the figure), a parameter setting unit, a display unit, an alarm device and the like; the main control unit is connected with the units.
Wherein,
the power conversion unit is used for converting commercial power into direct current working power, and specifically may include circuits for transformation, rectification and voltage stabilization.
Each compensation unit comprises a cold wafer, the cold wafer is wrapped and fixed by a shell, and other devices (such as a fixing band) can be used for wrapping or fixing the cold wafer, and the cold wafer is connected with the power conversion unit; an accommodating space is formed between the shell of each compensation unit and the cold wafer of the compensation unit and is used for accommodating the temperature sensing head of the air conditioner, and the inner wall of the shell of each compensation unit is coated with heat insulation paint which is used for insulating the cold wafer from the outside; in practical applications, the housing of the compensation unit may have different shapes and may be fixed to the cold plate in various ways.

and the alarm device is used for giving an alarm when the temperature sensed by the temperature sensing head of the power-saving device is within the alarm temperature range, and the alarm can be realized in the modes of sound, light and the like.

controlling all cold wafers not to work in a first temperature interval;
controlling all the cold wafers to work in turn in a second temperature interval;
and controlling all cold wafers to work in a third temperature interval.
For example, in one embodiment, in the cooling state, it is assumed that the lower limit of the first temperature interval is set to 30 ℃, the second temperature interval is set to 28 ℃ to 30 ℃, and the third temperature interval is set to 28 ℃ or less. When the ambient temperature sensed by the temperature sensing head is more than 30 ℃, all the cold wafers do not work, namely, refrigeration compensation is not carried out; when the ambient temperature sensed by the temperature sensing head is between 28 ℃ and 30 ℃, controlling all cold wafers to start in turn to perform refrigeration compensation; when the environmental temperature sensed by the temperature sensing head is below 28 ℃, all cold wafers are controlled to be started to perform refrigeration compensation.
Also, in one embodiment, in the heating state, it is assumed that the lower limit of the first temperature interval is 15 ℃, the second temperature interval is 13 ℃ to 15 ℃, and the third temperature interval is 13 ℃ or less. When the environmental temperature sensed by the temperature sensing head is lower than 13 ℃, all the cold wafers do not work, namely heating compensation is not carried out; when the ambient temperature sensed by the temperature sensing head is between 13 ℃ and 15 ℃, all cold wafers are controlled to start in turn (for example, work in turn for half an hour) to perform heating compensation; when the environmental temperature sensed by the temperature sensing head is higher than 15 ℃, all the cold wafers are controlled to be started to perform heating compensation.

and controlling the cold wafer corresponding to the sensor to work in a third temperature interval.

Wherein, should with the main control unit according to the ambient temperature that the temperature sensing head of being connected on the main control unit senses, the operating condition who controls this cold wafer is:

If the temperature at this point is 28.5 ℃. When the temperature sensing head judges that the room temperature is in the second temperature range, the power saving device controls all the cold wafers to work alternately or at intervals corresponding to the temperature sensing head, namely, the compensation regulator section is started to refrigerate the corresponding cold wafers, the peripheral temperature of the temperature sensing head of the air conditioner can be reduced to below 25 ℃ because the temperature sensing head of the corresponding air conditioner is arranged beside the cold wafers, and the control system of the air conditioner sends an instruction for stopping the compressor after knowing the condition. And along with the indoor temperature rise, if the temperature sensing head of the power saving device senses that the indoor temperature is in a third temperature range, the work of the compensation unit is stopped. The indoor temperature slowly rises, and when the temperature sensed by the air conditioner temperature sensing head is higher than 25 ℃, the air conditioner compressor starts to operate again; when the temperature sensing head of the power saving device senses that the indoor temperature is in the second temperature range, the compensator is controlled to work. This cyclic compensation is maintained until the present economizer senses no set temperature. The heating process and the compensation process are opposite.
To sum up, the utility model discloses communication computer lab air conditioner power saving device gathers ambient temperature in real time through the temperature sensing head to through the comparison with the settlement temperature, in ambient temperature is in the temperature interval of settlement, just carry out corresponding processing (like the power supply, stop etc.) to cold wafer, cause the environment of refrigeration or heating in the compensation unit, give the purpose of air conditioner temperature sensing head compensation, thereby control air condition compressor's start-up and stop. The aim of saving electricity is achieved, and the frequent starting and closing of the air conditioner compressor under low load can be prevented, so that the service life of the air conditioner is prolonged;
in addition, the utility model discloses a communication computer lab air conditioner power saving device can be used for compensating many air conditioners simultaneously, and it is very convenient to use;
furthermore, the utility model discloses a shell of the cold wafer of compensation unit among communication computer lab air conditioner economize on electricity device adopts the inner wall to scribble the mode that has thermal-insulated lacquer, and its thermal-insulated effect is very good, can make the temperature decline or the rising of cold wafer very rapidly.
