Abstract
Description
Technical Field
[0001] The present application relates to the technical field of air-conditioning temperature control, and in particular to a temperature control device for multiple zones of an air-conditioning. Background Art
[0002] As an indispensable part of modern industry and high-end buildings, process air conditioning systems are designed to provide precise and efficient temperature control to meet the stringent requirements of specific environments. Radiant heating technology is applied in the above system, and multiple heating areas are formed by several groups of radiant heaters, showing an efficient and evenly distributed heating solution. Radiant heaters do not rely on air convection to transfer heat, but directly radiate heat to objects in the form of electromagnetic waves. This heating method is more gentle and uniform, reduces dust agitation caused by air flow, and is conducive to maintaining indoor air quality. It is suitable for occasions with high requirements for environmental cleanliness, such as semiconductor workshops, precision laboratories, hospital operating rooms, etc. Since radiant heaters can be installed on ceilings, walls or other structures, they do not take up additional space, and can be flexibly arranged according to the structural characteristics of the building, making the system highly adaptable and integrated in design, and can be well integrated into various complex building environments.
[0003] The currently commonly used method of electronically adjusting power for temperature control is that when the radiant heater maintains the temperature, even if it only needs to run at low power, the system still keeps all heaters in the on state, and only achieves temperature fine-tuning by adjusting the output power. This working mode undoubtedly increases unnecessary energy consumption. In view of this, it has become an urgent need in the industry to develop a temperature control mechanism that can effectively schedule the start and stop of each radiant heater to achieve the goal of on-demand heating and precise energy saving. Utility Model Content
[0004] The present invention provides a multi-zone temperature control device for an air conditioner, and the specific implementation is as follows:
[0005] A multi-zone temperature control device for an air conditioner, comprising:
[0006] Several ventilation ducts, each of which is connected in parallel with several branch pipes, and a temperature sensor is installed at the end of the ventilation duct, and each branch pipe is installed with a radiation heater. By changing the number of radiation heaters that are turned on, the air supply temperature of the ventilation duct can be controlled;
[0007] The two ends of the power transmission branch line are respectively connected to the radiation heater and the collector, and the collectors are fixedly arranged equidistantly in the same direction. The power intake bus is connected to the busbar, and the busbar slides relative to the busbar wheels of each collector. The number of radiation heaters turned on is regulated by changing the number of collectors in contact with the busbar.
[0008] Based on the above technical solutions, through a set of busbars, a single movable busbar (or intelligent conductive rail) is used to link with multiple collectors to achieve precise start and stop control of multiple radiant heaters, thereby achieving energy-saving temperature control; by adjusting the position of the busbar mechanically or electrically, the number of contacts between the collector and the conductive area can be changed, thereby controlling the number of radiant heaters connected to the power supply; compared with traditional electric control power regulation, the system only starts the necessary heaters when needed, greatly reducing energy consumption. At the same time, reducing the no-load operation of the heater, improving the overall energy utilization efficiency, and reducing operating costs.
[0009] Preferably, it also includes a lifting component and a controller. The lifting component is a lead screw structure driven by a motor, and its output end is connected to the busbar; the signal output end of the controller is connected to each temperature sensor, and the motor is electrically connected to the signal input end of the controller.
[0010] Based on the above technical solution, the controller is connected to the temperature control structure of each group of ventilation ducts to achieve global unified control. The data collection of the temperature sensor and the position control of the busbar are realized with the help of the motor, so that the output temperature of the radiation heater group can be dynamically controlled.
[0011] By integrating temperature sensors, motor drives and busbar systems through the controller, an efficient and accurate global temperature management system is constructed; the system deploys high-precision temperature sensors at key locations of each ventilation duct, which continuously monitor the real-time temperature changes in the duct and transmit the data to the controller in real time; the motor is controlled to adjust the position of the busbar according to the controller's instructions, and the busbar is driven by the motor to move, which heater groups can be accurately selected to participate in the work, thereby achieving fine adjustment of the output heat; not only can the global unified control of all heater groups be achieved, but also personalized temperature setting and adjustment can be performed according to the specific needs of different ventilation ducts, thereby achieving energy-saving, efficient and comfortable heating effects. Through the above technical means, not only the energy efficiency ratio of the radiation heating system is significantly improved, energy consumption is reduced, but also the precise control of the ambient temperature is achieved, which improves the user's comfort and the intelligence level of the system.
[0012] Preferably, the busbar includes a mounting plate, on which a conduit is vertically arranged, the conduit is open on a side facing the collector, and a conductor is arranged in the conduit along its length.
[0013] Preferably, the length of the wire is greater than the distance between the current collectors at both ends.
[0014] Based on the above technical solution, the length of the wire is greater than the distance between the collectors at both ends, so that all the radiation heaters can achieve external output effects online at the same time.
[0015] Preferably, the lateral end of the conduit is configured to be closed, and each sliding wheel slides vertically into the opening at the top of the conduit, and its conductive end is connected to the wire.
[0016] Based on the above technical solution, the trolley wheel moves the busbar in and out from the top or bottom, and limits the trolley wheel laterally, thereby achieving overall stability during the lifting and lowering process of the trolley wheel.
[0017] Preferably, a knob switch is installed on the power transmission branch line, the outer peripheral surface of the rotating part of the knob switch is set as an outer gear ring, a rack is provided on the outside of the conduit, and the rack is meshed with the outer gear ring.
[0018] Based on the above technical solution, the passive circumferential rotation of the knob switch is triggered to open by the vertical lifting of the busbar and the rack and the meshing between the outer gear ring and the rack.
[0019] Preferably, the rack and the conduit are connected via an angled mounting bracket.
[0020] Preferably, the top of the rack and the top of the wire are arranged in a vertically staggered manner.
[0021] Based on the above technical solutions, in order to further improve the safety and stability of the system, an offset setting mechanism is adopted to ensure that the contact process between the sliding wheel and the conductive sliding wire is smoother and safer. When the sliding wheel just contacts the wire, the knob switch remains in the closed state, thereby preventing any unstable current that may be generated from flowing to the radiation heater. As the sliding wire slides along the sliding wheel to a stable connection position, the knob switch is passively opened. At this time, the power supply branch line is connected to the power supply, and the current begins to be stably transmitted to the radiation heater, effectively avoiding sparks or current shocks at the moment of contact, and protecting the safety of the heater and the entire electrical system.
[0022] In summary, this application includes the following beneficial technical effects:
[0023] 1. The utility model uses a movable busbar and changes the number of connections between it and the current collector, thereby controlling the number of energized radiant heaters to achieve output temperature regulation. The start and stop control of multiple radiant heaters can be achieved by controlling only a single busbar;
[0024] 2. The utility model realizes global unified control by connecting the controller to the temperature control structure of each group of ventilation ducts, collects data from the temperature sensor and uses the motor to realize the position control of the busbar, thereby realizing the dynamic control of the output temperature of the radiation heater group;
[0025] 3. The utility model has a simple structure. By dislocating the two, when the sliding contact wheel just contacts the conductor, the knob switch is not turned on and the power transmission branch line is not energized, thereby preventing the unstable current from being transmitted to the radiation heater when the two just contact.
