Description

The self-adaptive thermostatic-controlled energy-saving monitoring device of programme-controlled exchange machine room special air conditioner

Technical field

The present invention relates to a kind of special air conditioner, carry out the self-adaption constant temperature control of temperature, humidity, reach energy-conservation purpose being provided with in the programme-controlled exchange machine room.

Background technology

In the programme-controlled machine room, generally all be provided with a large amount of special air conditioners, to carrying out the control of temperature and humidity in the machine room, generally all be data to be set manually, to close or to start air conditioner quantity at present, temperature or humidity in the machine room are too high or too low, the Ren Suiqi nature not only causes waste of electric energy, and programme-controlled operation is caused fault easily.

Summary of the invention

For solving the automatic control problem of temperature, humidity in the aforementioned programme-controlled exchange machine room, the invention provides the self-adaptive thermostatic-controlled energy-saving monitoring device of a kind of programme-controlled exchange machine room special air conditioner, this device is that a singlechip CPU is by synchronous, asynchronous serial port, through communication chip, with temperature, the communication of humidity collector chip, simultaneously also with air-conditioning transcriber, wireless sending module communication; The air-conditioning transcriber is connected with all air conditioners in the programme-controlled machine room, gather the instant data of air conditioner, in good time environment temperature, humidity that temperature, humidity collector collect, with the temperature of setting, humidity ratio, singlechip CPU is sent instruction, and the startup of controlling certain air conditioner in certain zone whether; Temperature, humidity collector are arranged in each zone of dividing in the programme-controlled machine room; Control device also is provided with LCDs and keyboard.

Singlechip CPU respectively with temperature, the communication of humidity collector chip, or with air-conditioning transcriber and wireless sending module communication, by the variable connector chip controls.

Whether the startup that singlechip CPU is controlled all air conditioners in the programme-controlled machine room distributes the address decision by decoder for decoding.

The air-conditioning surplus capacity is by current ambient temperature and variation, air conditioner quantity, air conditioner refrigeration amount, heating frame quantity and machine room area decision.

The course of work of singlechip CPU Self Adaptive Control is:

(1) initialization, and calculate:

A, current indoor environment temperature, humidity (each zone in the machine room); , comprise ambient temperature;

B, the air conditioner under the current environment condition quantity of having more than needed;

C sets up automatic sorting data storehouse according to air conditioner quantity, refrigerating capacity, arrangement mode;

(2) do you arrive control time Time1? if do not arrive, go to 5;

(3) if arrive control time Time1, be foundation with maximum temperature value, minimum temperature value and the average temperature value of air conditioner institute corresponding region, freeze or heat control;

(4) be foundation with the high humility value of air conditioner institute corresponding region, minimum humidity value and medial humidity value, dehumidify or humidification control;

(5) to differentiating extraneous temperature, humidity variation Time1 constantly? if do not arrive, then go to step 11;

(6) do you if the external world is warm to differentiating, humidity changes Time2 constantly, then differentiates external environmental condition and change? if no change then changes step 11;

(7) if change, recomputate the air conditioner surplus capacity, and sort automatically again;

(8), calculate preferential closable air conditioner numbering more than needed according to the environment temperature, the humidity value that write down in the automatic sequencer procedure;

(9) is not the automatic surplus capacity control of air conditioner? if then close air conditioner more than needed;

(10) finish.

Described control time Time1 is that extraneous temperature, humidity change Time2 constantly, are the ambient temperature peak moment of living in of first three day by the time cycle decision of each compressor for air conditioner operation.

Programme-controlled machine room is divided into several regions, and the air conditioner in the zone is pressed region ordering, and each zone is provided with some temperature, humidity collector.

Description of drawings

Accompanying drawing 1 is a circuit block diagram of the present invention.

Accompanying drawing 2 is control flow charts of singlechip CPU of the present invention.

The specific embodiment

See also shown in the accompanying drawing 1, this device is the STC89C516RD of a singlechip CPU chip 1, by synchronous serial interface 9 chip Z85C30, the 82C51A of asynchronous serial port 11, through the RS422 of communication chip MAX489 mode and remote platform data link interface, mode through the RS485 of the MAX483 of communication chip 16, DS18B20T with Temperature sampler chip 19, the SHT71 communication of humidity collector chip 20, also pass through RS422 mode and 21 communications of air-conditioning transcriber of the MAX489 of communication chip 17 simultaneously, through the MAX202R of communication chip 13 RS232 mode and wireless sending module 18 communications; Air-conditioning transcriber 21 is connected with all air conditioners in the programme-controlled machine room, temperature, humidity collector are adopted 19,20 in good time environment temperature, the humidity that collect, with the temperature of setting, humidity ratio, singlechip CPU 1 is sent instruction, the startup of controlling certain air conditioner in certain zone whether; Temperature, humidity collector 19,20 are arranged in each zone of dividing in the programme-controlled machine room; Control device also is provided with LCDs 5 and keyboard 6.

Singlechip CPU 1 respectively with temperature, 19,20 communications of humidity collector chip, or with air-conditioning transcriber 21 and wireless sending module 18 communications, control by variable connector 10 chip CD4052.

Whether the startup of all air conditioners in the programme-controlled machine room of singlechip CPU 1 control, distributes the address decision by decoder 7 decodings.

Be that example explanation control procedure is as follows with first air conditioner A corresponding A zone below:

If current average temperature value is 24 ℃ (user can set) in the programme-controlled machine room, the machine room maximum temperature value is 25 ℃ (user can set), and Temperature sampler has 8 in the a-quadrant, records actual temperature and is respectively:

T1＝23.20℃

T2＝22.90℃

T3＝22.85℃

T4＝23.10℃

T5＝23.62℃

T6＝23.98℃

T7＝23.84℃

T8＝23.56℃

Then calculate average temperature value and the highest, minimum be respectively T average=23.38 ℃, minimum 22.85 ℃ of T, T are the highest=23.98 ℃.

First air conditioner A desired temperature this moment is 22 ℃, and the return air temperature value is 23 ℃, and state is refrigeration; This moment, control device is controlled air-conditioning, because of the T mean temperature less than T average criterion value, and the T maximum temperature is less than T highest goal value, the ambient temperature level of declare area A, belong to normal condition, control device makes the temperature that is provided with of air conditioner A be adjusted into 23 ℃ to air conditioner A sending controling instruction, and is consistent with the return air temperature value, air-conditioning becomes fan condition by refrigerating state, has saved the waste of energy that causes owing to extra refrigeration.
