Description

Background Technology

[0001] Large-space heating and air conditioning are primarily intended to meet the comfort needs of the people within them. However, a large portion of the energy used for heating and air conditioning is consumed in unused building facilities, resulting in significant waste. Furthermore, due to factors such as thermal pressure, airflow, and spatial distance, even with substantial energy expenditure, people within the space may still not achieve a comfortable environment.

[0002] Taking a tall factory building as an example, during heating, the upper area experiences higher temperatures due to thermal pressure, even though there is no human activity there and no need for heating. Conversely, the near-ground area of ​​the factory remains cold due to thermal pressure, failing to meet the factory's heating needs and thus hindering the provision of a comfortable working environment for ground heating. Workers who genuinely require heating are on the ground floor but cannot access it. The same problem exists in large factory buildings with vast areas occupied by workers. For instance, a large factory with only a small number of employees who typically move within limited areas would consume enormous amounts of energy to heat the entire building; individual heating and air conditioning would suffice for their needs.

[0003] With the popularization of intelligent, digital, and personalized equipment, heating and air conditioning equipment should also move towards intelligence and personalization. This invention explores this approach. By combining an intelligent digital tracking device with a follow-up air duct, it meets the personalized and intelligent requirements of personnel, while also saving energy, thus achieving the goal of benefiting the country and its people. Purpose of the invention

[0004] 1. With the popularization of intelligent digital equipment, heating and air conditioning equipment should also move towards intelligence. This invention explores this approach. By combining intelligent digital tracking devices with follow-up air ducts, it meets the personalized and intelligent requirements of personnel, while also saving energy and benefiting the country and its people.

[0005] 2. Existing heating and air conditioning terminal equipment such as radiators and fan coil units can only be installed in fixed locations, serving extremely limited areas. This invention aims to change this situation.

[0006] Currently, the application of personalized air supply devices in factories still has the following shortcomings: 1. The air supply direction of existing personalized air supply devices is all fixed and cannot be adjusted according to changes in people's positions. 2. Compared with current heating and ventilation facilities, new factory workstation fan coil units can achieve air supply within the area, which is more energy-efficient and environmentally friendly, and increases worker comfort. Technical solution

[0007] With the popularization of intelligent and digital equipment, heating and air conditioning equipment should also move towards intelligence. This invention explores this approach. By combining intelligent digital tracking devices with follow-up air ducts, it meets the personalized and intelligent requirements of personnel, saves energy, and achieves the goal of benefiting the country and its people.

[0008] To achieve the above objectives, this invention patent is implemented through the following technical solution.

[0009] A novel integrated follow-up workstation heating and air conditioning terminal device comprises five parts: an intelligent digital personnel tracking device, a follow-up air duct, a heat exchange device and an air supply device, and a housing.

[0010] The highlight of this invention is the addition of an intelligent digital personnel tracking device to the top of the air supply device. The intelligent digital personnel tracking device is combined with the follow-up air duct. By detecting the position of the person at the workstation, the personnel position information is transmitted to the control box via an electrical signal. Then, the control box issues a command to control the follow-up air duct to face the person at the workstation and to operate the heat exchange device and the air supply device to deliver the airflow of the appropriate temperature to the area where the person is staying.

[0011] This invention achieves personalized airflow to workstations by controlling the air delivery position and horizontal angle of the fan, thereby enhancing the comfort of factory workers. Furthermore, by eliminating the need for general heating and air conditioning, it improves energy efficiency in large spaces, avoiding the blind pursuit of overall space temperature targets, thus playing a positive role in energy conservation for large-space heating and air conditioning systems.

[0012] Furthermore, the intelligent digital tracking device consists of an intelligent digital personnel tracking device on top of the equipment and a control box connected to the following air duct. The infrared detector can use dual-band infrared detection technology to achieve three positioning methods: infrared sensor positioning, image analysis positioning, and infrared thermal imaging positioning. After locating the personnel, it can effectively transmit electrical signals to the central control box via signal lines. The control box is controlled by an internal CPU chip, which automatically transmits electrical signals to the following air duct through a pre-programmed sequence.

[0013] Furthermore, the follow-up air duct consists of a jet air outlet, the follow-up air duct itself, a steering mechanism, and a motor. The jet air outlet is circular, with its diameter determined by the actual air volume. The outer layer of the duct is painted for corrosion protection, and the air outlet can be wrapped in plastic for aesthetic purposes. An elbow is provided near the air outlet to facilitate downward air delivery when installed at a high location. The follow-up air duct and the steering mechanism are connected via flanges. The control box and motor are welded to the outside of the duct via brackets and can be treated for corrosion and explosion protection according to the factory's process requirements. When the motor receives an electrical signal from the control box, it drives the steering mechanism and the follow-up air duct to rotate in the direction of the personnel, achieving horizontal movement of the air outlet and thus enabling the fan coil unit to follow the personnel's position for personalized air delivery.

[0014] Furthermore, the ductwork and the heat exchanger are connected via flexible ductwork. This detachable component allows for adjustments in duct diameter and length, depending on the situation. Filters are installed at the heat exchanger connections and are replaced periodically.

[0015] Furthermore, the heat exchange device consists of a high-efficiency heat exchanger and a water pipe interface. The high-efficiency heat exchanger internally includes supply and return water pipes, a surface cooler, and fins. The water pipe interface is located on the side of the heat exchanger and connects to an external water pipe. Upon receiving a pneumatic electrical signal from the control box, the surface cooler activates, allowing the water in the pipes to exchange heat with the outside air, raising or lowering the air temperature within the heat exchanger, thus achieving cooling in summer and heating in winter.

[0016] Furthermore, the air supply device is a variable frequency high-efficiency centrifugal fan, equipped with an automatic start / stop device controlled by a control box. Both the heat exchange device and the air supply device are encased in a metal shell, which can be treated for corrosion and explosion protection depending on the actual situation. A return air vent is located at the bottom of the unit.

[0017] Furthermore, for ease of maintenance and repair, all of the above parts can be disassembled and reassembled.

[0018] The beneficial effects of this invention compared to the prior art are as follows: 1. This invention uses an intelligent digital tracking device to track workers at their workstations and automatically activate terminal equipment, achieving personalized air supply and effectively improving the comfort of workers in the workstation area.

[0019] 2. The system of general heating and air conditioning was eliminated. This improved the energy efficiency of large-space factory buildings. Instead of blindly pursuing overall space temperature targets, it improved the temperature of small workstation areas, thus playing a positive role in energy conservation for large-space heating and air conditioning.

[0023] Please refer to Figures 1 and 2. This invention patent provides a novel integrated follow-up workstation heating and air conditioning terminal device with dimensions of 1500×1000×500 mm. The novel integrated follow-up workstation heating and air conditioning terminal device comprises five parts: an intelligent digital personnel tracking device, a follow-up air duct, a heat exchange device, an air supply device, and a housing. The intelligent digital tracking device consists of an intelligent digital personnel tracking device 101 on the top of the device and a control box 102 connected to the follow-up air duct 202. The follow-up air duct includes a jet air outlet 201, a follow-up air duct 202, a steering mechanism 203, and a motor 204. The heat exchange device consists of a high-efficiency heat exchanger 302 and a water pipe interface 301. The air supply device is a variable frequency high-efficiency centrifugal fan 401. The follow-up air duct and the heat exchange device are connected by a flexible duct 601. For aesthetics and safety, the outer edge of the jet air outlet 201 can be wrapped with plastic, and the outside of the duct is painted with rust-proof and corrosion-resistant paint. The intelligent digital personnel tracking device 101 employs dual-band infrared detection technology and is made of aluminum alloy. It can accurately detect the location of personnel when they enter the work area. The control box 102 has a built-in CPU control chip, responsible for receiving signals from the intelligent digital personnel tracking device 101 and transmitting the electrical signals to the automatic motor 204, the high-efficiency heat exchanger 302, and the variable frequency high-efficiency centrifugal fan 401. The flange 205 connects the following air duct 202 and the steering mechanism 203.

[0024] The steering mechanism 203 is connected to the automatic control motor 204. Its internal structure is a worm gear mechanism; the worm is made of tin bronze, and the worm is made of 304 / 40 Cr stainless steel. Under the control of the automatic control motor 204, it can swing horizontally, increasing the air delivery angle. The connecting device 601 mainly connects the follow-up air duct and the heat exchange device. It can be lengthened according to actual needs and has an internal filter. The heat exchange device includes a high-efficiency heat exchanger 302 and a water pipe interface 301. The high-efficiency heat exchanger contains supply and return water pipes, a surface cooler, and fins.

[0025] The water pipe interface is located on the side of the heat exchanger and connects to the external water pipe. Upon receiving an electrical signal from the control box 204, the surface cooler automatically turns on its power and exchanges heat with the outside air, enabling cooling in summer and heating in winter. A variable frequency high-efficiency centrifugal fan 401 is located at the rear of the high-efficiency heat exchanger, compressing outside air into the air duct. The air duct shape can be square or circular, and its size depends on the air volume. A return air inlet 402 is located at the bottom of the high-efficiency heat exchanger 302, and a filter screen is installed at the return air inlet.

[0026] Figure 3 illustrates the workflow of the new type of fan coil unit for factory workstations. The entire control process begins with the intelligent digital personnel tracking device 101 first using infrared scanning technology to determine when personnel have entered the workstation area and lock their location. Then, the detector sends an electrical signal to the control box 102. The CPU chip in the control box 102 processes the signal and sends an electrical signal to the automatic motor 105, controlling the follow-up air duct to swing to a suitable angle. Electrical signals are then sent to the variable frequency high-efficiency centrifugal fan 401 and the high-efficiency heat exchanger 302 inside the heat exchange device to control the device's on and off states. The entire terminal device is remotely controlled by an automatic control system.
