Description

Technical Field

[0001] The invention relates to the technical field of fresh air systems, and in particular to an energy-saving device for a central air-conditioning fresh air system. Background Art

[0002] The central air conditioning fresh air system is a system that introduces fresh air into the room and processes and distributes it through the air conditioning system. Its main function is to provide fresh air and input it into the room through temperature and humidity control to maintain a comfortable indoor environment.

[0003] The functions of central air conditioners are the same as those of ordinary air conditioners, which mainly adjust the indoor temperature. However, the power consumption of heating during the use of air conditioning is much greater than that of cooling. This is because the power consumption of components such as electric auxiliary heating, compressors, and reversing valves is increased during the heating process. At the same time, the air conditioner also needs to blow the heat absorbed by the outdoor heat exchanger back into the room during heating. In this way, the indoor heat obtained during heating is more than the heat dissipated during cooling. Therefore, heating consumes more electricity than cooling.

[0004] However, the existing central air conditioning fresh air system has the following shortcomings:

[0005] When traditional air conditioners are used for heating, they mainly install adapter heaters in independent air ducts. The continuously compressed high-temperature airflow passes through the interior of the heater, and the pre-discharged airflow is heated by physical heating. However, there are still some shortcomings, such as:

[0006] 1) In order to prevent airflow from escaping in some areas, the existing central air conditioner electric auxiliary heating components usually have heaters that match the airway size. During use, multiple heating elements in the device are powered on. Since the airflow release amount is much smaller than the cross-section in the airway and multiple heating elements cannot be controlled independently, some heating elements do useless work, greatly increasing the power consumption of the air conditioner.

[0007] 2) The electric auxiliary heating components of traditional central air conditioners can only control the power of the heating elements according to the set temperature of the air conditioner. However, this method is highly blind and the air flow temperature after secondary heating cannot be accurately controlled, resulting in large differences in perceived temperature. Users need to repeatedly adjust the temperature.

[0008] Therefore, we propose an energy-saving device for the central air-conditioning fresh air system to solve the above-mentioned problems. Summary of the invention

[0009] The object of the present invention is to provide an energy-saving device for a central air-conditioning fresh air system. Through the gradient processing mechanism, the ability of each spiral high-resistance heating tube therein to be independently powered can be utilized to bake the connected metal air inlet tanks in turn, so as to achieve the purpose of heating the high-speed gas therein. Before each airflow is transmitted to the lower-level metal air inlet tank, the airflow temperature can be detected by the upper-level temperature sensor. The system components can analyze and judge based on the actual data. If it is consistent with the setting, the high-temperature airflow is discharged normally. Otherwise, the subsequent spiral high-resistance heating tubes are energized until the airflow temperature is heated to within the set range, thereby avoiding multiple heating elements being in a full load state to solve the problems raised by the above-mentioned background technology.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention sets a gradient processing mechanism, wherein a plurality of spiral high-resistance heating tubes are preset in the mechanism, and the same number of metal air inlet tanks are connected. The size of each metal air inlet tank is reasonably controlled so that each metal air inlet tank has a certain gas storage capacity.

[0024] 2. The present invention sets a gradient processing mechanism. The multiple metal air inlet tanks set in the mechanism can be superimposed to heat the circulating airflow. Every time the airflow is heated in a metal air inlet tank, it will be detected by the temperature sensor therein. The obtained actual data can be analyzed by relevant components in the electrical control box and compared with the set values ​​one by one. The number of airflow heating times is set, and the pre-discharge airflow temperature is accurately calibrated to the set range. Due to the reduction of the airway area, the same amount of gas will increase the air pressure in the airway, and the high-temperature gas can be squeezed and released quickly, reducing temperature loss and quickly balancing the indoor temperature. The user can quickly obtain the body temperature and avoid repeatedly adjusting the equipment temperature, which causes a heavy load on each component. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The effect achieved by the entire mechanism is: first install the equipment in the designated work area, the compressor unit tail pipe is fully connected to the top of the air inlet connector 19, and its external line is connected to the main power supply of the equipment to provide energy for multiple electrical components.

[0048] During the equipment heating stage, the equipment heating temperature is manually set, and the set data is temporarily stored in the electrical control box 733. The servo motor 21 is turned on to drive the impeller in the centrifugal unit 17 to rotate at high speed. The high-temperature compressed airflow continuously delivered by the external unit will be further accelerated in the centrifugal unit 17 and diffused from the discharge joint 18 to the filter bin 1. The airflow entering the body first crosses the interior of the layered filter assembly 15 to complete the filtration of impurities and dust, and then converges to the first transition bin 2. A designated drive motor 13 is turned on to drive the opening of a corresponding stop valve 12, and open one of the internal channels of the first air guide square tubes 11. Before the high-speed airflow enters the heating bin 4, the electrical control box 733 controls one of the independent power supplies 7 17 and the temperature sensor 729 are turned on, and its energy is transmitted by the conductive rod 719, the wire 716 and the first load-bearing frame 704, so that the corresponding spiral high-resistance heating tube 705 passes quickly, and the temperature released on the surface will continue to penetrate into the connected metal air inlet tank 706.

When the airflow enters the heating range of the spiral high-resistance heating tube 705, an airflow heating can be completed. The processed airflow will quickly contact the corresponding temperature sensor 729, and the obtained temperature data will be fed back to the electrical control box 733 by the receiver 731 in real time. If the temperature meets the requirements, the airflow The airflow will pass through the subsequent metal air inlet tank 706 in sequence under the transportation of the shunt pipe 709, and then be collected in the interior of the second transition chamber 5 by the transportation of the second connecting pipe 713 and the second air guide square tube 22, and finally be discharged from the front end of the release chamber 6. Otherwise, if the airflow temperature does not meet the requirements, the electrical control box 733 can synchronously turn on a subsequent independent power supply 717 and a temperature sensor 729 before the airflow enters the next metal air inlet tank 706, so that the connected spiral high-resistance heating tube 705 is energized, and the shunt pipe 709 can pour the airflow after the first heating from top to bottom into the interior of the subsequent metal air inlet tank 706, and complete the secondary heating of the airflow, and then the temperature sensor 729 at this position detects the airflow temperature, and the obtained data is fed back in real time In the electrical control box 733, a secondary analysis is performed. If the temperature meets the requirements through the above method, the airflow is released normally after treatment. If the conditions are still not met, the subsequent spiral high-resistance heating tubes 705 are opened one by one, and the number of airflow heating times is increased gradually until the airflow meets the set range. After the equipment is turned off, each electric push rod 724 is opened synchronously to retract its inner axis into the cavity, driving the associated frame 725 and its connected components to move downward until each sealing head 726 is completely separated from the interior of the external cover 721. The relevant components in the electrical control box 733 are used to time the trapped gas release time. After the time is reached, each sealing head 726 is reset immediately to prevent excessive external dust from entering each metal air inlet tank 706 to prevent airway blockage.
