Description

Intelligent environment controller

technical field

The utility model relates to the technical field of environmental control, in particular to an intelligent environment control machine.

Background technique

The reasons why electrical equipment or interiors (in rooms or prefabricated cabins) (hereinafter referred to as electrical equipment) currently require environmental control include the following:

1. Heat dissipation requirements: It is necessary to keep the temperature inside the equipment below the temperature required by the equipment or standard to prevent the equipment from being shut down or burned out due to excessive temperature;

2. Insulation requirements: the electrical and electronic devices in electrical equipment, the normal working temperature needs to be >-10 ℃ (adjustable according to special equipment), and the atmospheric temperature ≦ -10 ℃ (adjustable according to special equipment), it should be insulated to prevent The temperature is lower than the temperature required by electrical and electronic devices;

3. Requirements for low temperature protection: In harsh weather with extremely low atmospheric temperature, active heating needs to be activated to prevent low temperature and ensure the minimum temperature requirements in electrical equipment;

4. Dehumidification requirements: Changes in the temperature difference of electrical equipment and changes in atmospheric humidity can cause moisture condensation inside the electrical equipment, causing hidden dangers or failures, so dehumidification and condensation prevention are required;

5. Requirements for dust prevention: Dust enters the interior of electrical equipment, causing accumulation, resulting in a rapid decline in the heat dissipation of electrical and electronic devices, so that the heat cannot be dissipated and overheated and burned;

6. The demand for energy saving and carbon emission reduction; electrical equipment, high energy consumption of air conditioners for heat dissipation, high energy consumption of heaters used for low temperature protection, and high energy consumption of dehumidifiers or heaters used for dehumidification;

7. Control requirements for hazardous gases: Hazardous gases, such as biogas (biogas generated by humus in cables), hydrogen (hydrogen generated during charging and discharging of batteries in new energy battery energy storage equipment), etc., still need to be detected and tested under thermal insulation conditions. Exhaust these hazardous gases and ensure the safety of electrical equipment. To sum up, the electrical equipment needs a new type of equipment that can exchange airflow inside and outside the electrical equipment. Heating, dehumidification and dustproof environmental control device;

8. Intelligent management and control system;

9. Easy to install and low cost.

Existing equipment or systems that control the internal environment (also known as) of electrical equipment are divided into two categories:

One, airtight isolation

The air inside and outside the airtight isolation type is isolated and there is no convection. It mainly represents equipment such as air conditioners (such as central air conditioners, industrial air conditioners, and cabinet air conditioners) and dehumidifiers. of.

1. Air conditioner

Advantages: fully functional;

shortcoming:

1) High energy consumption

1.1) High energy consumption for cooling and heat dissipation: when used as a heat dissipation function, the industrial air conditioner has a nominal heat dissipation power of 1KW and requires 0.5KW (according to the conventional industrial air conditioner energy efficiency level 2, such as the industrial air conditioner of the internationally renowned industrial air conditioner brand Pfannenberg, Germany parameter), the ratio of dissipation (heat dissipation) consumption (power consumption) is 2; under the current dual-carbon target, it has seriously failed to meet the control objectives of energy saving and carbon reduction;

1.2) High energy consumption for dehumidification: The principle of air conditioning dehumidification is to inhale the air at room temperature into the air conditioner, and under the refrigeration of the compressor, the inhaled air is cooled until the water vapor in the inhaled air condenses into water and is discharged to dehumidify. High power consumption, usually an industrial air conditioner with a dehumidification capacity of about 150mL per hour consumes 1.5KW;

2) The environmental control performance is poor and cannot meet the standard requirements of the internal environment of electrical equipment

2.1) In high temperature weather, the cooling and heat dissipation capacity is poor and does not meet the standard requirements. The reason is that the air conditioner needs to inhale the cooling heat into the electrical equipment, and then compress the air containing the heat through the compressor and heat it up to a temperature higher than the external atmospheric temperature of the electrical equipment. A temperature of ≧10℃ is used to dissipate heat into the atmosphere;

When the atmospheric temperature is less than or equal to 30°C, the air conditioner is easy to cool and dissipate heat, but when the atmospheric temperature is greater than 30°C, the compressor needs to compress and heat the air that needs to be dissipated to ≧40°C to effectively dissipate heat. The temperature of the heat island centered on the outdoor unit of the air conditioner decreases from the center of the heat island to the ambient temperature to an atmospheric temperature of 30°C, which further reduces the heat dissipation capacity and increases the energy consumption. Usually, the internal temperature of the electrical equipment exceeds the standard requirements.

In a typical embodiment, the electrical equipment in an electrical equipment room generates about 90KW of heat, and four large air conditioners are configured to cool and dissipate heat. Each air conditioner has a cooling capacity of 26KW, and the cooling capacity of the four air conditioners is about 104KW. , that is, the cooling capacity of the electrical equipment room is about 104KW. Theoretically, the cooling capacity is greater than the calorific value, and the temperature should be controlled to be lower than the atmospheric temperature, but in fact, the temperature cannot be controlled below the temperature required by the standard. The specific site survey date is around 15:30 on July 8, 2021. The local outdoor air temperature is 29°C, the indoor temperature of the electrical equipment is 40°C, and the corresponding temperature rise is 11K. In summer, the temperature in this area can reach above 34°C, then when the outdoor temperature reaches 34°C, the indoor temperature corresponding to SVG is 45°C and 50°C respectively. ℃, so the equipment has a safety hazard of overheating.

2.2) In low temperature weather, the heating capacity cannot meet the technical requirements

The heating capacity of the air conditioner is poor under the condition of low atmospheric temperature. When the atmospheric temperature is less than or equal to 0°C, the heating capacity is greatly reduced. When the atmospheric temperature is less than or equal to -20°C, the heating capacity is almost lost, and the heating should be strengthened below this temperature. However, it cannot work, so it does not meet the standard requirements.

3) The hazardous gas in the electrical equipment (electrical room) cannot be discharged, because the air conditioner is a device that isolates the internal airflow from the external airflow. Therefore, the hazardous gas from the electrical equipment (electrical room) cannot be effectively discharged, so it is not suitable for hazardous gas. gas generation conditions.

2. Dehumidifier solution

The dehumidifier only has dehumidification energy, and does not have the functions of heat dissipation, heat preservation and low temperature protection.

3. Central air conditioner

Central air conditioners are used in buildings and workshops, and cannot be used for electrical equipment or electrical rooms, nor do they meet the needs of electrical equipment, mainly:

1) It is bulky and cannot be installed on electrical equipment;

2) The price is too high, higher than the price of electrical equipment, and has no economic practicability;

3) High energy consumption, the reason is the same as that of industrial air conditioner;

4) When the atmosphere is high temperature, the heat dissipation capacity is poor. The reason is: the central air conditioner is used in the working condition where there is almost no heat source inside. , unable to meet the technical requirements of electrical equipment; when the atmospheric temperature is low, there is no need for air conditioning to dissipate heat;

5) When the atmosphere is low temperature, the heating capacity is poor, and the reason is the same as that of the industrial air conditioner;

6) There is no dehumidification function, and there is no and no dehumidification device;

7) The hazardous gas cannot be discharged, because the central air conditioner is a system that isolates the internal and external airflow, so the hazardous gas cannot be discharged from the electrical equipment;

8) There is no intelligent control for electrical equipment.

Two, open convection

Open convection type internal and external air is not isolated, can be automatically or under forced air cooling, mainly represents equipment or products with wind windows, filter fans, fresh air systems.

1. Filter fan scheme:

The filter fan mainly ventilates and dissipates heat for electrical equipment.

Advantages: low energy consumption, heat dissipation of 4KW, corresponding power consumption of 0.13KW, and a dissipation ratio of about 30, which is far greater than that of air conditioners, effectively saving energy and reducing carbon emissions; it has dust-proof performance and solves the hidden danger of dust during ventilation.

shortcoming:

1) No heat preservation is possible, because the filter fan belongs to the air exchange type heat dissipation, so even if the filter material is installed, the air can still flow inside and outside. In this way, in the low temperature atmospheric environment, the cold air enters the electrical equipment from the filter fan, so the heat preservation cannot be satisfied. Technical requirements;

2) It cannot prevent low temperature because the filter fan has no heating device, so in the harsh low temperature environment, the electrical equipment cannot be heated to prevent low temperature;

3) It cannot be dehumidified because a dehumidification device cannot be configured.

2. Fresh air system

The fresh air system can ventilate and dissipate heat, and its corresponding disadvantages are as follows:

1) The air volume is small, that is, the heat dissipation capacity is low, which cannot meet the heat dissipation requirements of electrical equipment. The reason is that the fresh air system is for buildings, that is, for households, office buildings, and commercial buildings;

2) It cannot be kept warm because the fresh air system belongs to the internal and external air exchange system, which cannot be used under extreme outdoor low temperature conditions;

3) Dehumidification is not possible because there is no dehumidification device and corresponding dehumidification control.

In summary, the current solutions do not meet the requirements of the current operating environment standards for electrical equipment (electrical rooms), mainly due to the rapid construction of new energy power generation and 5G communications, resulting in a large number of electrical equipment being placed outdoors. The requirements are becoming more and more stringent, and now there is no corresponding product or solution that can solve this problem.

In addition, under the dual-carbon target situation, there is no energy-saving and carbon-reducing product to meet the needs of the operating environment in outdoor electrical equipment.

At present, the high temperature, dust, humidity and low temperature cause frequent failures and even fires of outdoor electrical equipment. In order to ensure stable and safe operation, this kind of environmental control machine is urgently needed to solve these problems with low-carbon emission and energy-saving performance.

Please refer to FIG. 1 to FIG. 4 , the present invention provides an intelligent environment control machine, which specifically includes a casing 1, and the casing 1 is provided with a wind window 2 and an external sensor 3, and the wind window 2 is the inlet or outlet of the external airflow, It has a rainproof function, and the windshield 2 can be equipped with a filter to achieve the function of preventing solid objects from entering the interior of the electrical equipment. The external protection level of the environmental control machine is IP65, which completely exceeds the protection level of the air conditioner IP54. It can replace the air conditioner in terms of performance; The housing 1 is provided with a damper 12 and a fan 6 in sequence behind the windshield 2. The damper 12 includes a damper or a valve leaf; the damper of the damper 12 has a controllable opening and closing structure, and the damper of the damper 12 has a controllable opening and closing structure. Ground continuous opening function, that is, from complete closing, controllable opening amount, to complete opening; after the external airflow duct is opened, it has the condition of external airflow convection of the electrical equipment. When the windshield is closed, the external airflow duct is closed, so that the internal and external airflow of the electrical equipment is blocked and isolated from each other, which can realize the function of thermal insulation of electrical equipment. , which can better save energy and reduce carbon emissions; the air window 2, the air valve 12 and the fan 6 are compactly installed and combined to form a controllable open and closed airflow duct, that is, the airflow outside the airflow duct, which is used for the internal and external airflow of electrical equipment controllable exchange.

An air duct construction device 7 and a mounting plate 9 are arranged between the air valve 12 and the fan 6. The air duct construction device 7 is provided with an internal and external airflow duct separation device 14, a heater 13 and an airflow parameter sensor 11, and the internal and external airflow ducts are separated. The device 14 is in a "Z" shape, and the air duct is divided into an outer airflow channel and an inner airflow channel. The outer airflow channel is used for the exchange of internal and external airflows of the electrical equipment, and the internal airflow channel is used for the internal airflow of the electrical equipment. At the same time, the air duct construction device 7 A common channel for internal and external airflow is constructed. When the air valve 12 is opened, the external airflow channel is opened and the internal airflow channel is closed. In this way, when the airflow is exchanged between the inside and the outside, when the outside air is drier than the internal air, the airflow can be used directly to dry the interior. Dehumidification; when the air valve 12 is closed, the outer air passage is closed and the inner air passage is opened; the heater 13 is arranged at the common place of the inner and outer air passages, so that when the inner and outer air flow is exchanged, the incoming humid air can be heated and dehumidified; the inner air flow circulates When it is installed, the internal airflow can be heated according to the internal environmental parameters of the electrical equipment to realize the dew point control heating and dehumidification function and the internal airflow circulation dehumidification function.

Specifically, the heater 13 in the present invention is designed at the position where both the outer airflow duct and the inner airflow duct pass through, and the design of the outer airflow duct and the heater 13 is used to solve the practical problem, and it is also effective for the incoming air. High humidity airflow for dehumidification. In rainy, snowy and foggy weather and the electrical needs to be dissipated, it is also necessary to solve the wet and dew condensation conditions of the electrical equipment, you can open the air valve, fan and heating device, and the design of the external air duct allows the air entering from the outside (the humidity is close to 100% at this time). ) must pass through the heating device, and through the heated air flow, the humidity will drop to the humidity required by the micro-environment of the electrical equipment.

Principle: The temperature rises by 1°C, and the humidity drops by about 5%;

Premise 1: In rainy and foggy days, the temperature is usually ≦28°C, and the temperature in snowy days is lower; at this time, the humidity is close to 100%, and we calculate it as 100%;

Premise 2: The allowable temperature in the standard electrical equipment is less than or equal to 45°C, and the allowable humidity is less than or equal to 90%;

Process: The external air enters the air at 28°C, and the temperature rises to 32°C through the heater, and the humidity drops to 85%.

Moreover, the existing heating devices are all placed inside the electrical equipment. When the electrical equipment is equipped with a closed isolation type heat dissipation device (that is, through the shell, the interior of the electrical equipment is isolated from the external atmospheric environment), the defect is that the moisture does not go out during heating and dehumidification, and It is still inside the electrical equipment, so the dehumidification is not complete; an additional dehumidifier needs to be configured, which increases the cost and increases the hidden danger of electrical equipment. Because the dehumidifier occupies the internal space, it still needs a water conduit, and the water pipes and joints will age over time. Cause water leakage and cause hidden dangers. Moreover, when the electrical equipment is equipped with an open convection heat dissipation device, most of the heat is leaked out of the electrical equipment after the heater is restarted, so the heating consumes a lot of energy and the effect is small, and it is completely ineffective in an outdoor low temperature environment.

The utility model designs a heater 13 on the inner side of the air valve 12, that is, on the side leading to the electrical equipment, and at the same time, the heater 13 is also designed at the position where both the outer air duct and the inner air duct pass through, This utility model design can not only allow the humid air to enter to heat and dehumidify when the air valve 12 is opened, but also can heat the equipment to prevent low temperature after the air valve is closed, and the heat will not be dissipated.

Using the actual problem solved by the design of the internal air duct and the heater 13, the internal heating and dehumidification of the electrical equipment is carried out, specifically: the internal dew point control heating and dehumidification: according to the temperature and humidity detected by the internal sensor, the condensation temperature can be automatically obtained, Under the condition of external low temperature, close the external airflow duct, and use the internal airflow duct, heater and fan to send hot airflow into the electrical equipment, so as to control the temperature and humidity, and open the external airflow when the moisture exceeds a certain value. Air ducts to discharge moisture, a comprehensive method to achieve moisture and anti-condensation.

Use the actual problems solved by the design of the internal airflow duct and heater to internally heat the electrical equipment to prevent low temperature: when the external low temperature, close the external airflow duct to keep warm, but when the external ambient temperature is too low, use the electrical equipment inside. When the heat generated by the operation of the device does not meet the insulation requirements, the internal airflow duct, heater and fan are started to send heat to the electrical equipment for heating and low temperature prevention.

The utility model has the following advantages:

1. The compact design of the air window, air valve and fan has the highest ventilation efficiency, which solves the problem of being too large and not compact to be applied to electrical equipment, and also solves the linkage control of the air valve and fan that matches the heat dissipation requirements of electrical equipment. Ventilation, heat preservation and intelligent control of internal and external air exchange and dehumidification; and on the basis of wind windows and fans, air valves are designed. This design constitutes a controllable airflow channel. The airflow exchange function, when closed, has the function of isolating inside and outside, and then cooperates with the linked fan to realize the functions of ventilation, heat dissipation and heat preservation;

2. The heater is compactly designed in the position where both the outer air duct and the inner air duct pass through, which solves the problem of heating and preventing low temperature under severe low temperature conditions;

11. The environmental control machine can be used alone or as a set. When used in a complete set, it is composed of air inlet and air outlet respectively.

Please refer to Figure 5. The environmental control machine can be used alone or as a set. When used as a set, the air intake and the outgoing air are respectively composed. Specifically, the first intelligent environment control machine 102 and the second intelligent environment control machine 103 are installed on the electrical equipment 101, and the specific functions are as follows:

1. Realization of 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 the external airflow channel is opened, so that the internal and external airflow can be naturally convective heat dissipation under the action of temperature difference. If natural convection still cannot meet the heat dissipation requirements of electrical equipment, the controller starts the fan to perform forced airflow convection and increase the heat dissipation to meet the heat dissipation requirements of electrical equipment. After one or a group of environmental control machines are forced to convect the air to dissipate heat, one or a group of environmental control machines or corresponding modules inside the environmental control machines can be expanded to increase the heat dissipation and meet the heat dissipation requirements of electrical equipment.

2. The realization of the function of dehumidification of the intake air: in the rainy, snowy and foggy weather, when heat dissipation is required, it is necessary to dehumidify the air flow entering the electrical equipment. We often encounter rainy days, and the traffic lights are easily out of control, which is to control the traffic and other electrical cabinets There is no dehumidification function of the air flow, and some power outages are also caused by this.

Specifically, under the condition that the environmental control machine has started to dissipate heat, the controller starts the heater according to the detected environmental parameters. Since the heater is located on the common channel of the internal and external airflow, after the heater is started, the incoming airflow can be controlled. Dehumidification solves the hazards or hidden dangers caused by atmospheric humidity to electrical equipment in rainy, foggy and snowy weather.

3. Realization of heat preservation function: When the atmospheric environment is low temperature, if the temperature is lower than 10 ℃, the heat generated by the operation of the electrical and electronic devices inside the electrical equipment should be used to maintain heat preservation without starting the heating device (such as air conditioning or heating). Heater heating), which can greatly save energy and reduce carbon.

Specific operation: According to the data collected by the sensor, when heat preservation is required, the controller controls the windshield driver to close the air valve, so as to realize the isolation of the electrical equipment from the atmospheric environment, and use the self-heating operation of the electrical equipment to maintain heat preservation, greatly saving energy and reducing carbon emissions. .

4. Realization of heating and anti-low temperature function: when the atmospheric environment is too low, such as the temperature is lower than -10 ℃, the heat preservation can no longer meet the temperature required for the best operation of electrical equipment. The heating efficiency is low, and even the heating capacity is lost. Therefore, use the heater configured in the environmental control machine to perform heating to prevent low temperature.

Specifically, when the windshield has been closed, the inner air passage is opened, the controller starts the heater, and at the same time starts the fan, the air flow in the electrical equipment is driven by the fan, passes through the inner air passage, is heated by the heater, and returns to the To electrical equipment, the air flow reciprocates in this way, which can quickly heat the electrical equipment to prevent low temperature, solve the problem that the heating effect of the air conditioner is not increased at too low temperature, and also solve the problem that the ordinary heater cannot flow quickly and evenly heat the air. the problem.

5. The realization of the dehumidification function of the external circulation of air flow: in spring, autumn and winter, the outside air is often dry. Due to the underground access and exit of electrical cables, moisture is generated from the bottom, which is likely to cause internal moisture. This air changer can effectively solve the problem. the question.

Specific operation: According to the internal and external temperature and humidity detected by the sensor, under the condition that the electrical equipment is not low temperature, according to the humidity difference, the controller opens the air valve, puts dry air into the electrical equipment, and discharges the moisture inside the electrical equipment. When the humidity difference is large, the fan can be controlled to start to accelerate the discharge of moisture. After discharge, the fan and damper are automatically closed according to the humidity difference. In this way, natural dry air is used for dehumidification, which not only saves energy and reduces carbon, but also dehumidifies more effectively.

6. The realization of the heating and dehumidification function controlled by the air circulation dew point: in the extremely low temperature snow weather, the air circulation dehumidification function cannot meet the dehumidification function, so the air circulation heating and dehumidification function is activated;

Specific implementation: After starting the internal circulation dehumidification of the air flow, the controller starts the heater according to the collected temperature and humidity and the corresponding dew point temperature, and heats the reciprocating air flow, so as to increase the temperature of the electrical equipment and prevent condensation on the top. At the same time, the formed condensation can be dried to solve the problem of top condensation and frost in extremely low temperature snow weather.

7. Hazardous gas discharge function: Hazardous gases, such as biogas (biogas generated by humus in cables), hydrogen (hydrogen generated during charging and discharging of batteries in new energy battery energy storage equipment), etc., still need to be detected and tested under thermal insulation conditions. Exhaust these hazardous gases to ensure the safe operation of electrical equipment;

Specific implementation: The controller detects the hazardous gas inside the electrical equipment or its cable trench, and when the concentration is the installation condition, the controller opens the outer airflow channel through the windshield driver to discharge the hazardous gas from the electrical equipment.

8. The function of energy saving and carbon emission reduction: According to the standard, the ambient temperature in the electrical equipment needs to be -10℃≦T≦40℃, so when the atmospheric temperature is less than 35℃, ventilation and heat dissipation can be used, but it needs to meet the performance of the air conditioner ( Protection grade: IP54, that is, dustproof grade 5, waterproof grade 4; dehumidification performance);

The protection level of the environmental control machine of the utility model is IP65, which meets and exceeds the protection level of the air conditioner; at the same time, the utility model has a dehumidification function, so it can completely replace the air conditioner, thereby greatly saving energy and reducing carbon emissions, as follows:

8.1 Energy saving of power consumption for the same heat dissipation: For the same heat dissipation, the energy consumption of the environmental control machine is less than 4% of that of the air conditioner, and the energy saving rate is more than 90%; the atmospheric temperature is less than 35 ℃, according to the detected internal and external temperature and humidity, the controller passes By controlling the opening of the damper and the fan to force air cooling and heat dissipation, effective heat dissipation and energy saving can be achieved.

8.2 Energy saving through natural convection heat dissipation through the opening and closing of air dampers: due to the fact that the electrical equipment generates a large amount of heat during operation, it is a spontaneous high heat source, which is different from the small or no heat source in the residential room. In addition, the electrical equipment equipped with industrial air conditioners are sealed. Therefore, it is impossible to dissipate heat by natural convection of the air. In this case, when the atmospheric temperature is usually 10°C, it is necessary to start the air conditioner to cool and dissipate the electrical equipment.

However, when the environmental control machine solution is applied, the outdoor air temperature is less than or equal to 25°C, and the damper and damper are all opened, and the natural convection can be used to achieve effective heat dissipation. Therefore, under the atmospheric temperature of -10°C to 25°C, it can greatly save energy. Reduce carbon emissions.

8.3 Energy saving in low temperature environment by controlling the opening and closing function of the air valve and the self-heating of electrical equipment: because electrical equipment requires low temperature usually above -10℃, the temperature in electrical rooms such as prefabricated cabins is required to be above 10℃; The temperature when there is no one in the room is required to be above 18 °C, so the air conditioner or environmental control machine needs to be heated when the atmosphere is low to meet the above requirements.

The ambient temperature of the atmosphere is -15°C to 10°C. According to the temperature inside and outside the electrical equipment, the controller can control the opening and closing of the damper and the damper, and then use the electrical equipment to run self-heating, which can meet the above requirements and save energy.

When the atmospheric temperature is lower than -15°C, the air conditioner basically loses its heating capacity. Therefore, when the air conditioner is used, it operates at this temperature, and the energy consumption is high, but it has almost no heating capacity, so it cannot effectively prevent low temperature. Under this condition, the environmental control machine is used. After the controller closes the damper of the damper, the heater and the fan are started to heat the electrical equipment, which can effectively and quickly heat up.

9. The function of intelligent operation.

The above is that the controller performs intelligent automatic control according to the environmental parameters collected by the sensor; at the same time, it can also realize the calculation and data provision of the heat dissipation margin, which is convenient for users to intelligently operate and maintain in advance; the fan starts to automatically react under the control of the controller. It is used to automatically clean up the sundries and dust accumulated on the wind window or filter material, and reduce manual maintenance.

The above specific embodiments can be combined with each other, and the parameters in the embodiments can be adjusted according to equipment requirements, and the same or similar concepts or processes may not be repeated in some embodiments.

The technical features of the above embodiments can be combined arbitrarily (as long as there is no contradiction in the combination of these technical features), for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described; The written examples should also be considered to be within the scope of the description in this specification.
