Description
Technical Field
The invention relates to the technical field of environment control, in particular to an intelligent environment control machine.
Background
The reasons why the environmental control is required for the electric equipment or the indoor (room or prefabricated cabin) (hereinafter referred to as electric equipment) include the following:
1. the requirement of heat dissipation: the temperature of the temperature controller in the equipment is required to be lower than the temperature required by the standard, so that the equipment is prevented from being shut down or burnt out due to overhigh temperature;
2. the requirement of heat preservation: the temperature of electric and electronic devices in the electric equipment is required to be-10 ℃ in normal operation (adjustable according to special equipment), and the atmospheric temperature is ≦ 10 ℃ (adjustable according to special equipment), so that the temperature is required to be kept from being lower than the temperature required by the electric and electronic devices;
3. the need for low temperature protection: in severe weather with extremely low atmospheric temperature, active heating needs to be started to prevent low temperature and ensure the minimum temperature requirement in the electrical equipment;
4. the requirement of dehumidification: the temperature difference change of the electrical equipment and the change of the atmospheric humidity can cause humidity condensation in the electrical equipment, thereby causing hidden danger or failure, and dehumidification and condensation prevention are needed;
5. the requirement of dust prevention: dust enters the interior of the electrical equipment to cause accumulation, so that the heat dissipation of the electrical and electronic devices is rapidly reduced, and the heat cannot be dissipated and is over-heated and burnt;
6. the requirements of energy conservation and carbon emission reduction are met; the energy consumption of an air conditioner for heat dissipation of the electrical equipment is high, the energy consumption of a heater for low temperature prevention is high, and the energy consumption of a dehumidifier or heater for dehumidification is high;
7. control requirements for hazardous gases: harmful gases, such as biogas (biogas generated by humus in a cable), hydrogen (hydrogen generated in the charging and discharging process of a new energy battery energy storage equipment battery) and the like, still need to be detected and discharged under the condition of heat preservation, and the running safety of the electrical equipment is guaranteed, so that the electrical equipment needs a new device in an exchange type of air flow inside and outside the electrical equipment, and the environmental control device can ventilate, dissipate and dissipate the harmful gases, can be closed at proper time for heat preservation, can actively heat, and can dehumidify and prevent dust;
8. an intelligent management and control dimensional system;
9. convenient installation and low cost.
The existing devices or systems for managing and controlling the internal environment (also called) of electrical devices are divided into two major types:
one, closed isolated form
The air inside and outside the closed isolated type is isolated and has no convection, and mainly represents equipment such as a central air conditioner, an industrial air conditioner, a cabinet air conditioner and the like and a dehumidifier, and the pressure of the closed isolated type is mainly used for refrigerating and radiating by utilizing the thermal principle of a compressor.
1. Air conditioner
The advantages are that: the functions are complete;
the disadvantages are as follows:
1) high energy consumption
1.1) high energy consumption of refrigeration and heat dissipation: when the heat dissipation device is used as a heat dissipation function, the heating power of 1KW of the industrial air conditioner is nominally dissipated, the power consumption of 0.5KW (according to the conventional industrial air conditioner energy efficiency grade 2, such as the industrial air conditioner parameter of the International famous industrial air conditioner brand Germany Bainerberg) is required, and the dissipation (heat dissipation) power consumption (power consumption) ratio is 2; under the current double-carbon target, the control target of energy conservation and carbon reduction is seriously not met;
1.2) high dehumidification energy consumption: the principle of air conditioning dehumidification is that normal temperature air is sucked into an air conditioner, and the sucked air is cooled until steam in the sucked air is condensed into water to be discharged under refrigeration of a compressor, so that dehumidification is realized, the dehumidification amount is small, the energy consumption is high, and the power consumption of an industrial air conditioner with the dehumidification capacity of about 150mL per hour is 1.5KW generally;
2) poor environmental control performance and can not meet the standard requirement of the internal environment of the electrical equipment
2.1) in high-temperature weather, the refrigerating and heat dissipating capacity is poor, and the standard requirement cannot be met, because the air conditioner sucks heat which needs to be cooled in the electrical equipment, and then the air containing the heat is compressed and heated by a compressor to a temperature which is higher than the external atmospheric temperature of the electrical equipment by not less than 10 ℃ so as to dissipate the heat into the atmosphere;
when the atmospheric temperature is less than or equal to 30 ℃, the air conditioner is easy to refrigerate and dissipate heat, but when the atmospheric temperature is greater than 30 ℃, the compressor needs to compress and heat the air needing to be dissipated to be greater than or equal to 40 ℃, so that heat can be effectively dissipated, but the air conditioner external unit forms a heat island with the air conditioner external unit as the center under a continuous heat source, the temperature is decreased to 30 ℃ from the center of the heat island to the surrounding temperature, so that the heat dissipation capacity is further reduced, the energy consumption is increased, and the internal temperature of the electrical equipment exceeds the standard requirement generally.
In a typical embodiment, the heating value of the electrical equipment in a certain electrical equipment room is about 90KW, 4 large air conditioners are configured for cooling and heat dissipation, the cooling capacity of each air conditioner is 26KW, the cooling capacity of 4 air conditioners is about 104KW, and the total power consumption is about 40KW, that is, the cooling capacity of the electrical equipment room is about 104 KW. Theoretically, the refrigerating capacity is larger than the heating value, the temperature can be controlled to be lower than the atmospheric temperature, but actually the temperature can not be controlled to be lower than the temperature required by the standard, the specific field investigation date is about 7 months, 8 days and 15:30 in 2021 year, the local outdoor atmospheric temperature is 29 ℃, the indoor temperature of the electrical equipment is 40 ℃, the corresponding temperature rise is 11K, the temperature in the area can reach more than 34 ℃ in summer, and then the indoor temperatures corresponding to the SVG are 45 ℃ and 50 ℃ respectively when the outdoor temperature reaches 34 ℃, so that the safety hazard of over-temperature exists in the equipment.
2.2) in low-temperature weather, the heating capacity can not meet the technical requirements
Under the condition of low temperature of the atmosphere, the air conditioner has poor heating capacity, the heating capacity is greatly reduced when the atmospheric temperature is less than or equal to 0 ℃, the heating capacity is almost lost when the atmospheric temperature is less than or equal to-20 ℃, and the air conditioner cannot work under the condition that the heating working condition is just strengthened below the atmospheric temperature, so the air conditioner cannot meet the standard requirement.
3) Harmful gas in the electrical equipment (electrical room) cannot be discharged because the air conditioner is a device for isolating the inner airflow from the outer airflow, and therefore, the harmful gas in the electrical equipment (electrical room) cannot be effectively discharged, and therefore, the air conditioner is not suitable for the working condition of generating the harmful gas.
2. Dehumidifier scheme
The dehumidifier only has dehumidification energy and does not have the functions of heat dissipation, heat preservation and low temperature prevention.
3. Central air conditioner
Central air conditioning is used for building and buildings such as factory building, can not be used for electrical equipment or electric room, also does not satisfy electrical equipment's demand simultaneously, mainly is:
1) the volume is large, and the device cannot be arranged on electrical equipment;
2) the price is too high and is higher than that of electrical equipment, and the economic practicability is not realized;
3) the energy consumption is high, and the reason is the same as that of an industrial air conditioner;
4) when the atmosphere is at high temperature, the heat dissipation capability is poor, and the reason is as follows: the central air conditioner is used for the working condition that no heat source exists inside, the heat source is the heat of a human body and the heat of a computer, and the electrical equipment in the industry has large heat productivity and small volume, and cannot meet the technical requirements of the electrical equipment when the atmosphere is at high temperature; when the atmospheric temperature is low, the air conditioner is not used for heat dissipation;
5) when the atmosphere is at low temperature, the heating capacity is poor, and the reason is the same as that of an industrial air conditioner;
6) no dehumidification function, no and no dehumidification device;
7) harmful gas cannot be discharged because the central air conditioner is a system for isolating internal and external air flows, so that the harmful gas cannot be discharged out of the electrical equipment;
8) there is no intelligent control suitable for electrical devices.
Two, open convection type
The open convection type internal and external air is not isolated, and can be automatically or under the condition of forced air cooling, and mainly represents equipment or products comprising air windows, filtering fans and fresh air systems.
1. The scheme of the filtering fan is as follows:
the filtering fan is mainly used for ventilating and radiating heat of the electrical equipment.
The advantages are that: the energy consumption is low, the heat dissipation capacity is 4KW, the corresponding power consumption is 0.13KW, the heat dissipation ratio is about 30, the energy consumption is far greater than that of an air conditioner, the energy is effectively saved, and the carbon emission is reduced; has dustproof performance, and solves the hidden trouble of dust during ventilation.
The disadvantages are as follows:
1) the heat cannot be preserved because the filter fan belongs to airflow exchange type heat dissipation, so even if the filter material is installed, air can still flow inside and outside, and thus, under a low-temperature atmospheric environment, cold air enters the electrical equipment from the filter fan, so that the heat cannot be preserved, and the technical requirement cannot be met;
2) the low temperature cannot be prevented because the filter fan has no heating device, so that the electrical equipment cannot be heated to prevent the low temperature in a severe low-temperature environment;
3) dehumidification is not possible because a dehumidification device cannot be configured.
2. Fresh air system
The new trend system can ventilate and dispel the heat, and its shortcoming that corresponds is as follows:
1) the air volume is small, namely the heat dissipation capacity is low, and the requirement of the heat dissipation capacity of electrical equipment cannot be met, because a fresh air system is oriented to buildings, namely household, office buildings and commercial buildings;
2) the heat preservation can not be realized, and the fresh air system belongs to an internal and external air exchange system and can not be used under the condition of extreme outdoor low temperature;
3) dehumidification is not possible because there is no dehumidification device and corresponding control of dehumidification.
In summary, various existing schemes do not meet the requirements of the current operating environment standards of electrical equipment (electrical rooms), and mainly because new energy power generation and 5G communication are rapidly built, a large amount of electrical equipment is placed outdoors, so that the requirements on the internal environment of the electrical equipment are more and more strict, and a corresponding product or solution which can solve the problem does not exist at present.
In addition, under the condition of double carbon targets, no energy-saving and carbon-reducing product is provided for meeting the requirement of the operating environment in outdoor electrical equipment.
At present, the outdoor electrical equipment with the area caused by high temperature, dust, moisture and low temperature has frequent failure and even fires, and the environment control machine is urgently needed to solve the problems with low-carbon emission and energy-saving performance in order to ensure the stable and safe operation.

The invention provides an intelligent environment control machine (which can be called as 'ring control machine' for short), which is a device or a product which is arranged on electrical equipment or indoors (rooms and prefabricated cabins) (called as electrical equipment for short) and is used for controlling the internal environment (called as microenvironment) of the electrical equipment, such as ventilation and heat dissipation, heat preservation, heating, low temperature prevention, dehumidification, harmful gas discharge, dust prevention, intelligent automatic control and data management, and is used for solving the problem that the electrical and electronic devices are frequently failed or even burnt due to the bad internal environment caused by the change of the atmospheric environment and the change of the operation of the internal electrical and electronic devices in various electrical equipment at present.
The environment control machine is also a variable which is generated by uncertain atmospheric environment and uncertain operation of electrical equipment and causes harm to the operation of the electrical equipment, and is changed into a good environment parameter which is stable to the operation of the electrical equipment, so that the safe and stable operation of the electrical equipment is ensured, and a power-assisted intelligent power grid and various intelligent electric related equipment or systems are stably and reliably operated.
Referring to fig. 1 to 4, the present invention provides an intelligent environment controller, which specifically includes a housing 1, wherein a window 2 and an external sensor 3 are disposed on the housing 1, the window 2 is an inlet or an outlet of an external airflow and has a rainproof function, the window 2 can be configured with a filter to realize a function of preventing a solid object from entering the interior of an electrical device, is an external protection level IP65 of an environment control machine, completely exceeds an air conditioner protection level IP54, and can replace an air conditioner in performance; an air valve 12 and a fan 6 are sequentially arranged in the shell 1 behind the air window 2, and the air valve 12 comprises a windshield or a valve blade; the wind shield of the wind valve 12 has a controllable opening and closing structure, and the wind shield of the wind valve 12 has a controllable continuous opening function from full closing and controllable opening amount to full opening; after the external airflow duct is opened, the external airflow convection condition of the electrical equipment is achieved, the matching performance according to the requirements of heat dissipation, dehumidification, heat preservation and the like is realized by controllable continuous opening, and the internal environment management and energy-saving carbon emission reduction of the electrical equipment are better performed; when the windshield is closed, the outer airflow duct is closed, so that the inner airflow and the outer airflow of the electrical equipment are not communicated and are isolated from each other, the heat preservation function of the electrical equipment can be realized, and the energy conservation and the carbon emission reduction can be better realized; the air window 2, the air valve 12 and the fan 6 are compactly installed and combined to form an air flow duct with controllable opening and closing, namely an air flow outer air flow duct, which is used for controllable exchange of inner air flow and outer air flow of electrical equipment.
An air channel constructing device 7 and a mounting plate 9 are arranged between an air valve 12 and a fan 6, an inner air flow air channel and an outer air flow air channel separating device 14, a heater 13 and an air flow parameter sensor 11 are arranged in the air channel constructing device 7, the inner air flow air channel and the outer air flow air channel separating device 14 are Z-shaped, the air channel is divided into an outer air flow channel and an inner air flow channel, the outer air flow channel is used for exchanging the inner air flow and the outer air flow of electrical equipment, the inner air flow channel is used for flowing the inner air flow of the electrical equipment, meanwhile, the air channel constructing device 7 constructs a channel shared by the inner air flow and the outer air flow, when the air valve 12 is opened, the outer air flow channel is opened, the inner air flow channel is closed, and therefore, when the inner air flow and the outer air are exchanged, the inner air can be directly dried and dehumidified by the air flow; when the air valve 12 is closed, the outer air flow channel is closed, and the inner air flow channel is opened; the heater 13 is arranged at the common use of the inner and outer airflow channels, thus, when the inner and outer airflow channels are exchanged, the incoming humid air can be heated and dehumidified; when the internal airflow circulates, the internal airflow can be heated according to internal environmental parameters of the electrical equipment, so that the dew point control heating and dehumidifying function and the internal airflow circulating and dehumidifying function are realized, the internal airflow heating can also be realized, and the internal heating and low-temperature prevention functions of the electrical equipment are realized.
Specifically, the heater 13 of the present invention is designed at a position where both the outer air flow duct and the inner air flow duct pass, and the design of the outer air flow duct and the heater 13 is utilized to solve practical problems and also dehumidify the incoming high humidity air flow. In rainy and snowy weather and in electrical needs to dissipate heat, the working condition of moisture condensation of electrical equipment needs to be solved, the air valve, the fan and the heating device can be opened, the design of the outer airflow air channel enables the airflow entering from the outside (the humidity is close to 100 percent at the moment) to pass through the heating device, and the humidity of the airflow heated up by heating is reduced to the humidity meeting the demands of the microenvironment of the electrical equipment.
The principle is as follows: the temperature is raised to 1 ℃, and the humidity is reduced by about 5 percent;
precondition 1: in rainy and foggy days, the air temperature is usually less than or equal to 28 ℃, and the air temperature is lower in snowy days; at this point the humidity is close to 100%, we calculate as 100%;
precondition 2: according to the allowable temperature in the standard electrical equipment is less than or equal to 45 ℃, and the allowable humidity is less than or equal to 90%;
the process is as follows: the external air flow is 28 ℃, the temperature is increased to 32 ℃ by the heater, the humidity is reduced to 85%, and the temperature difference of 13(45-32 ℃) is utilized to well dissipate heat of the electrical equipment, but the humidity is reduced to the humidity allowed by the electrical equipment.
In addition, the existing heating devices are all arranged in the electrical equipment, and when the electrical equipment is provided with the closed isolated heat dissipation equipment (namely, the interior of the electrical equipment is isolated from the external atmospheric environment through the shell), the defects are that moisture is not removed during heating and dehumidification, but is still in the electrical equipment, so that the dehumidification is not thorough; the dehumidifier needs to be additionally arranged, the cost is increased, meanwhile, the hidden danger of electrical equipment is increased, and because the dehumidifier occupies the internal space, the water guide pipe is still needed, and the hidden danger is caused by water leakage and sprinkling due to the fact that the water pipe and the joint are aged for a long time. When the electric equipment is provided with the open convection type heat dissipation equipment, most heat is leaked out of the electric equipment after the heater is started, so that the heating energy consumption is large, the effect is small, and the electric equipment is completely ineffective in outdoor low-temperature environments.
The invention designs that the heater 13 is arranged at the inner side of the air valve 12, namely one side leading to the electric equipment, and the heater 13 is also designed at the position where the outer air flow passage and the inner air flow passage pass through.
The practical problem that the design of utilizing interior air current wind channel and heater 13 was solved carries out inside intensification dehumidification to electrical equipment, specifically: controlling the internal dew point to increase temperature and dehumidify: according to the temperature and humidity detected by the internal sensor, the condensation temperature can be automatically obtained, the external air flow air channel is closed under the external low-temperature condition, the internal air flow air channel, the heater and the fan are utilized to send hot air flow into the interior of the electrical equipment, temperature control and humidity control can be carried out, moisture exceeds a certain value, the external air flow air channel is opened, the moisture is discharged, and the moisture and condensation prevention are realized by a comprehensive method.
The practical problem that the design of utilizing interior air current wind channel and heater was solved carries out the interior heating to electrical equipment and prevents the low temperature: when outside low temperature, close outer air current wind channel, keep warm, but outside ambient temperature is low excessively, utilizes the heat that the device operation in the electrical equipment produced, when unsatisfying the heat preservation demand, then begins interior air current wind channel, heater and fan, send the heat to heat in the electrical equipment and prevent the low temperature.

11. the ring control machine can be used independently or used in a matched way, and air inlet and air outlet are respectively formed when the ring control machine is used in a complete set.
Referring to fig. 5, the ring control machine can be used alone or in combination, and when used in a set, the ring control machine respectively forms an inlet flow and an outlet flow. Specifically, the first intelligent environment controller 102 and the second intelligent environment controller 103 are installed on the electrical device 101, and the specific functions are as follows:
1. the realization of the heat dissipation function: according to the environmental parameters detected by the sensor, when the electrical equipment needs to dissipate heat, the controller controls the windshield driver to open the windshield of the air valve, and then the outer airflow channel is opened, so that the inner airflow and the outer airflow can naturally convect and dissipate heat under the action of temperature difference, and if the natural convection cannot meet the heat dissipation requirement of the electrical equipment, the controller starts the fan to force airflow convection to increase the heat dissipation capacity so as to meet the heat dissipation requirement of the electrical equipment. After one or a group of ring control machines are subjected to forced air flow convection heat dissipation, the corresponding module inside one or a group of ring control machines or ring control machines can be expanded to increase the heat dissipation capacity and meet the heat dissipation requirement of electrical equipment.
2. The function of inlet flow dehumidification is realized: when the rain, snow and fog weather, when needing the heat dissipation, need dehumidify the air current that gets into electrical equipment simultaneously, when we often meet rainy day, traffic lights is out of control easily, and the dehumidification function that control traffic electricity cabinet does not have the admission flow causes exactly, and some power failure accidents also so arouse.
Specifically, under the radiating operating mode has begun in the ring accuse machine, the controller starts the heater according to the environmental parameter that detects, because the heater is located inside and outside air current shared channel, consequently after starting the heater, just can dehumidify the entering air current, solve when rain fog snow weather, harm or hidden danger that the atmospheric humidity caused electrical equipment.
3. The realization of the heat preservation function: when the atmospheric environment is at low temperature, if the temperature is lower than 10 ℃, the heat generated by the operation of the electric and electronic devices in the electric equipment is utilized to preserve the heat without starting a heating device (such as an air conditioner or a heater) so as to greatly save energy and reduce carbon.
The specific operation is as follows: according to data collected by the sensor, when heat preservation is needed, the controller controls the windshield driver to close the air valve, isolation between the interior of the electrical equipment and the atmospheric environment is achieved, self-heating is performed by the electrical equipment, heat preservation is achieved, and energy and carbon are greatly saved.
4. The realization of the heating low-temperature prevention function: when the atmospheric environment is too low, for example, the temperature is lower than-10 ℃, at this time, the heat preservation can not meet the temperature required by the optimal operation state of the electrical equipment, and at this temperature, the basic heating efficiency of the air conditioner is low, even the heating capacity is lost. Therefore, the heater configured by the ring control machine is used for heating and preventing low temperature.
Specifically, under the condition that the windshield is closed, the inner airflow channel is opened, the controller starts the heater, the fan is started simultaneously, the airflow in the electrical equipment is driven by the fan to pass through the inner airflow channel, is heated by the heater and returns to the electrical equipment, the airflow circulates in a reciprocating mode, the electrical equipment can be rapidly heated to prevent low temperature, the problem that the heating effect is not increased when the air conditioner is at low temperature is solved, and the problem that the ordinary heater cannot rapidly flow and rapidly and uniformly heat the air flow is solved.
5. The realization of the air flow outer circulation dehumidification function: in spring, autumn and winter, the outside air is dry, moisture is generated from the bottom due to the underground access of the cable inside the electrical equipment, and internal moisture is easily caused.
The specific operation is as follows: according to the internal and external temperature and humidity detected by the sensor, under the condition that the electric equipment is not low in temperature, the air valve is opened by the controller according to the humidity difference, dry air is put into the electric equipment, meanwhile, moisture in the electric equipment is discharged, and when the humidity difference is large, the fan can be controlled to start to discharge the moisture with higher speed. After the air is discharged, the fan and the air valve are automatically closed according to the humidity difference. Therefore, natural dry air is used for dehumidification, and energy conservation, carbon reduction and dehumidification are more effective.
6. The realization of the heating and dehumidifying functions of the air flow internal circulation dew point control: in the extremely low temperature snow weather, the air flow internal circulation dehumidification function can not meet the dehumidification function, so the air flow internal circulation heating dehumidification function is started;
the specific implementation is as follows: after the air current inner loop dehumidification is started, the heater is started by the controller according to the collected temperature and humidity and the corresponding dew point temperature, the air current which circulates in a reciprocating mode is heated and heated, so that the temperature of the electrical equipment is raised, the top condensation is prevented from being generated, and the formed condensation can be dried at the same time, and the difficult problems of the top condensation and the frost condensation in the extremely low-temperature snow weather are solved.
7. Hazardous gas exhaust function: harmful gases, such as biogas (generated by humus in the cable), hydrogen (generated in the charging and discharging process of a new energy battery energy storage device battery), and the like, still need to be detected and discharged under the condition of heat preservation, so that the operation safety of electrical equipment is guaranteed;
the method specifically comprises the following steps: the controller opens the air flow outer channel through the windshield driver according to the detection of harmful gas in the electrical equipment or in a cable duct of the electrical equipment under the installation condition of concentration, and the harmful gas is discharged from the electrical equipment.
8. Energy conservation and carbon emission reduction: according to the standard, the environmental temperature in the electrical equipment needs to be-10 ℃ and T40 ℃, so that when the atmospheric temperature is 35 ℃, ventilation and heat dissipation can be adopted, but the performances of the air conditioner (protection grade: IP54, namely dust-proof grade 5, waterproof grade 4 and dehumidification performance) need to be met;
the protection grade IP65 of the environment-friendly control machine meets and exceeds the protection grade of an air conditioner; meanwhile, the invention has a dehumidification function, so that the invention can completely replace an air conditioner, thereby greatly saving energy and reducing carbon emission, and the invention specifically comprises the following steps:
8.1 energy saving with the same heat dissipation: the energy consumption of the environment-controlled machine is less than 4% of that of the air conditioner, and the energy saving rate is more than 90%; the atmospheric temperature is below 35 ℃, and according to the detected internal and external temperature and humidity, the controller controls the opening of the air valve windshield and the operation of the fan to force air cooling for heat dissipation, so that effective heat dissipation and energy conservation can be realized.
8.2 through the energy-conservation of the natural convection heat dissipation of air blast gate switching: because the electrical equipment has large self heating value during operation, belongs to a spontaneous high heat source, and is different from a resident indoor micro or non-heat source, and the electrical equipment provided with the industrial air conditioner is sealed, the natural convection heat dissipation of air cannot be realized, so that the air conditioner needs to be started to refrigerate and dissipate heat of the electrical equipment when the atmospheric temperature is 10 ℃.
But when the scheme of the environment control machine is applied, the outdoor atmospheric temperature is less than or equal to 25 ℃, the air valve windshield is opened for mining, and the effective heat dissipation can be realized by utilizing natural convection, so that the energy-saving and carbon-reduction emission can be greatly realized at the atmospheric temperature of-10-25 ℃.
8.3 energy conservation in low-temperature environment by controlling the opening and closing functions of the air valve and self-heating of the electrical equipment: the low temperature of the electrical equipment is required to be above-10 ℃, and the temperature of an unmanned air chamber such as a prefabricated cabin is required to be above 10 ℃; the temperature of an electric chamber such as a prefabricated cabin and the like when no person exists is required to be more than 18 ℃, so that an air conditioner or a ring control machine is required to heat at low atmospheric temperature to meet the requirements.
The atmospheric environment temperature is-15 ℃ to 10 ℃, the air valve is controlled to open and close by the controller according to the collected temperature inside and outside the electrical equipment, and the electrical equipment is used for running self-heating, so that the requirements can be met, and energy is saved;
when the atmospheric temperature is lower than-15 ℃, the air conditioner basically loses the heating capacity, so when the air conditioning scheme is adopted, the air conditioner runs under the temperature condition, the energy consumption is high, but the heating capacity is almost not available, and the low temperature cannot be effectively prevented. Under this situation, the ring control machine is adopted, and after the controller closes the air valve windshield, the heater and the fan are started to heat the electrical equipment, so that the temperature can be effectively and rapidly increased.
9. Intelligent operation function.
The controller carries out intelligent automatic control according to environmental parameters acquired by the sensor; meanwhile, the calculation of the heat dissipation allowance and the data supply can be realized, so that a user can intelligently operate and maintain in advance; the fan starts to automatically rotate reversely under the control of the controller to generate air volume, and the fan is used for automatically cleaning sundries and dust accumulated on an air window or a filter material, so that manual maintenance is reduced.
