Description

Technical Field

[0001] The utility model relates to the technical field of radiation air-conditioning equipment, in particular to a multifunctional radiation air-conditioning device. Background Art

[0002] Radiant air conditioning (TABS) is a technology that uses the principle of radiation for cooling and heating. By lowering or raising the temperature of the interior surfaces of building envelopes, cold or hot radiating surfaces are created. Indoor temperature is regulated through radiant heat exchange between these radiating surfaces and the human body, furniture, and other surfaces of the building envelope. Radiant air conditioning systems can heat or cool indoor air by installing hot and cold ducts within the building envelope, or by adding radiant panels to ceilings or exterior walls, or laying floor heating panels beneath the ground (for ease of description, radiant panels and floor heating panels are collectively referred to as transducers below). The main advantages of radiant air conditioning include energy savings and comfort. Because it relies on radiant heat exchange, radiant air conditioning can provide sufficient heat at lower temperatures, thereby reducing energy consumption. Furthermore, by transferring heat through building surfaces such as walls, floors, or ceilings, radiant air conditioning prevents cold air from directly reaching the human body, providing a more uniform and comfortable indoor environment.

[0003] The general structure of existing radiant air conditioners includes an outdoor unit and an indoor unit, a control system based on a PLC, etc., and the outdoor unit and multiple indoor units (including a surface cooler and a fan, etc., when the fan is in operation, the wind force acts on the surface cooler, and the cold water or hot water in the surface cooler provides cooling or heating for the room), and a transducer (installed on the indoor wall or ceiling), etc., are connected in parallel through pipes. During operation, the outdoor unit uniformly provides cooling or heating liquid to multiple indoor units and transducers. Although the above operating mode meets the needs of use to a certain extent, it still has the following technical disadvantages due to structural limitations. First, because the outdoor unit is connected in parallel with multiple indoor units and transducers in the room through pipes, the number of pipes required is large, and installation is relatively complicated, which is not conducive to improving work efficiency and increases cost investment. Second: When working, the booster pump will pressurize the cold or hot medium output by the main unit and pump it out to the indoor units or transducers in each room. Due to the different number of rooms in each area, the length of the pipes used is different. If the pipes are relatively long, the room at the end of the pipe may not be effectively supplied with cold or hot medium (the pressure at the end of the pipe is relatively low), which will have an adverse effect on its cooling or heating. On the contrary, if the pipes are relatively short, the pressure in the pipes may be too high, which will lead to unnecessary waste of electricity. Third: In order to achieve a good temperature control mode, the existing radiant air conditioner is equipped with humidity and temperature sensors (including ambient temperature sensors and pipe temperature sensors) at the main unit. Then the control system controls the temperature of the hot and cold water (that is, refrigerant or heat medium) output by the radiant air conditioner according to the detected temperature or humidity data. The above control mode is based on the ambient temperature, humidity and pipe temperature data at the outdoor unit. This will bring a problem. The relevant data at the main unit is actually deviated from the temperature and humidity of each room, and the temperature and humidity of different rooms also deviate. The unified mode cannot effectively meet the temperature and humidity adjustments of each room (for example, the indoor temperature is lower than the outdoor temperature, and the humidity is lower than the outdoor humidity. The indoor temperature and humidity controlled according to the outdoor temperature and humidity cannot reach consistency), and it cannot bring a better user experience. Fourth, the internal air conditioner (serpentine coils with finned heat and cooling fins installed on the outside of the coils, with spacing between adjacent heat and cooling fins to ensure air circulation) and the fan are arranged in a front-to-back configuration. The UV germicidal lamps, which are used for sterilization, are installed at the air inlet of the air conditioner. This generates considerable fan noise during operation. Furthermore, the light generated by the UV germicidal lamps is relatively easily radiated externally (it can only sterilize one side of the air conditioner), potentially adversely affecting user health. Taking all of these factors into consideration, it is particularly necessary to provide a radiant air conditioner that integrates multiple functions, is easy to install, and offers a better user experience. Utility Model Content

[0004] In order to overcome the drawbacks of existing radiation air conditioners due to structural limitations as described in the background technology, the present invention provides a multifunctional radiation air conditioner that integrates multiple indoor devices into one, with a compact structure. The indoor and outdoor units installed in each room are connected in parallel through pipes, and the indoor unit in each room is connected to the transducer in series. During installation, the staff only needs to connect the corresponding two interfaces of the outdoor unit with the two interfaces of the indoor unit to achieve quick installation, thereby improving the installation speed and efficiency. Each indoor unit is equipped with a booster pump, and the sensors matched with the control system of each indoor unit can collect the temperature, humidity and pipe temperature of each room in real time. The temperature and humidity data of each room can be accurately adjusted through a one-position two-way proportional valve, a booster pump, a fan, etc., thereby providing users with a more comfortable experience and achieving energy-saving effects. The fan and ultraviolet sterilization lamp of the indoor unit are installed at the inner end of the V-shaped structure surface cooler, which reduces the noise of the fan, and simultaneously sterilizes and disinfects the two inner ends of the surface cooler, and reduces the adverse effects of ultraviolet leakage on user health.

[0007] Furthermore, the first liquid outlet end of the electric proportional valve can be fixedly connected to the liquid inlet end of the radiation plate or floor heating plate separately, and the liquid outlet pipe of the radiation plate or floor heating plate, the return liquid pipe of the main unit and the second liquid outlet end of the electric proportional valve are fixedly connected in parallel.

[0008] Furthermore, the control system is not limited to PLC, and can also adopt a single chip microcomputer module or a small computer system.

[0009] Furthermore, the fan and the booster water pump are respectively a variable frequency fan and a variable frequency booster water pump, and the shape of the surface cooler is not limited to one, and can be any one of the structures surrounding the fan.

The signal output ports 9 and 10 of the control system A1 are respectively connected to the power input terminals of the electric proportional valve M1 via wires.

The control system is not limited to PLC, and can also adopt a single-chip microcomputer module or a small computer system. The electric proportional valve M1 has a liquid inlet and two liquid outlets. The control signal input of the electric proportional valve M1 is one of a current and a voltage signal. The fan F and the booster water pump M are a variable frequency fan and a variable frequency booster water pump respectively. The appearance of the surface cooler 101 is not limited to one type and can be any type of structure surrounding the fan. The ultraviolet sterilization lamp H can also adopt any type of lamp with a sterilization function.

[0018] Figure 1 、 2As shown in , 3, the utility model is based on the radiation air conditioning body, The radiation principle is used for cooling or heating (the hot or cold water output by the outdoor unit 4 enters the multiple indoor unit surface coolers 101 and the transducer 2 through the liquid outlet pipe, and the hot water after heat dissipation or the cold water after cooling output by the surface cooler 101 and the transducer 2 returns to the outdoor unit through the return liquid pipe of the outdoor unit 4 for recycling). By lowering or raising the temperature of the inner surface of the enclosure structure, a cold or hot radiation surface is formed, and the indoor temperature is adjusted by the radiation heat exchange between these radiation surfaces and the human body, furniture and other surfaces of the enclosure structure. The radiation air conditioning system body heats or cools the indoor air by setting hot and cold pipes in the enclosure structure, or adding radiation panels on the ceiling or outer surface of the wall, and laying floor heating panels under the ground to achieve the purpose of raising or lowering the indoor temperature. Relying on radiation heat exchange, the radiation air conditioning body can provide sufficient heat at a lower temperature, thereby reducing energy consumption. In addition, the radiation air conditioning transfers heat through building surfaces such as walls, floors or ceilings, avoiding the direct blowing of cold wind on the human body, and can provide a more uniform and comfortable indoor environment (the above is an existing mature technology and will not be elaborated in this application).

[0019] Figure 1 、 2 As shown in Figure 3, in the present invention, the specific application of the radiation air conditioner body includes the following process. Step (1) After the staff installs multiple sets of outdoor units 4 and indoor units 1 in place, the liquid inlet pipes of the booster water pumps M of the multiple sets of indoor units 1 are connected to the liquid outlet pipes 41 of the outdoor units through pipes, the first liquid outlet end of the electric proportional valve M1 and the liquid inlet pipe of the indoor transducer 2 (floor heating plate or radiation plate) are fixedly connected through pipes, the liquid outlet pipe of the transducer 2 and the first end of a three-way pipe 3 are connected through pipes, and the second and third ends of the three-way pipe 3 are respectively connected to the second liquid outlet end of the electric proportional valve M1 and the return liquid pipe 42 of the outdoor unit through pipes, so that the multiple sets of indoor units and outdoor units are connected in parallel through pipes; through the above, the transducer 2 and the indoor unit 1 do not need to be separately connected in parallel with the liquid outlet pipe 41 of the outdoor unit 4 through pipes, which saves the number of pipes, reduces the installation workload, and improves safety and efficiency. In step (2), when the booster water pump M1 is working, the cold water or hot water input from the outdoor unit is pressurized and pumped into the surface cooler 101 and the energy conversion plate 2. After heat dissipation or cooling, the heat medium or refrigerant flows back into the main unit for recycling and reuse. In this step, since the water pressure is increased by the booster water pump, it can prevent the pipe connecting the outdoor unit 4 and the indoor unit 1 from being too long, causing the room at the end of the pipe to be unable to effectively obtain the cold or hot medium supply, which has an adverse effect on its cooling or heating. In addition, when the pipe is relatively short, the pressure in the pipe is too high, resulting in unnecessary waste of electricity.

[0020] Figure 1 、 2As shown in FIG3 , in step (3), after the AC power enters the power input terminal of the power module A5, the control system A1, and the electric proportional valve M1, the above-mentioned mechanisms are powered on and work (the control system A1 controls the ultraviolet sterilization lamp and the negative ion generator to be powered on and work at the same time), the power module A5 outputs a DC 24V power supply to the power input terminal of the humidity sensor A3 and the two sets of temperature sensors A21 and A22. The humidity sensor A3 and the two sets of temperature sensors A21 and A22 respectively detect the humidity data, indoor temperature data and the outlet pipe temperature data of the booster water pump M in real time, and output them to the control system A3. System A1 has three signal input terminals 13, 11, and 12 (the larger the humidity or temperature data, the higher the signal voltage or current entering the control system A1, and vice versa). Two sets of temperature sensors and humidity sensors respectively collect real-time indoor temperature, the external temperature of the booster water pump outlet, and the indoor temperature data, and then output current signals that dynamically change with temperature and humidity to the signal input terminal of the PLC (control system A1). Control system A1 controls the operating frequency of the booster pump M and fan F, as well as the valve core opening of the electric proportional valve M1, according to the size of the input signals. In the heating mode of the outdoor unit system, when the indoor temperature is low and the humidity is high, the control system A1 controls the working frequency of the booster pump (the higher the working frequency, the higher the output power, and the amount of liquid medium pumped into the surface cooler) and the fan (the higher the working frequency, the higher the output power, the larger the amount of air sucked in by the negative pressure, and the higher the heat blown out by the air). This increases the working frequency, provides more heat medium for the surface cooler and the transducer, and the amount of hot air blown out by the fan blades is greater, the indoor temperature rises, and the humidity decreases (in this mode, the control system outputs a higher control current signal to control the electric proportional valve M1, the valve core of the first liquid outlet end of the electric proportional valve M1 is opened to a large extent, the liquid medium flow entering the transducer is relatively large, and the liquid medium flow through the second liquid outlet is relatively large). When the indoor temperature is high and the humidity is low, control system A1 controls the operating frequency of the booster pump (which decreases the operating frequency, output power, and the amount of liquid pumped into the surface cooler) and the fan (which decreases the operating frequency, output power, and the amount of air drawn in under negative pressure, reducing the amount of heat blown out by the air). This reduces the operating frequency, providing less heat medium to the surface cooler and the transducer. The amount of hot air blown out by the fan blades is even smaller, lowering the indoor temperature and maintaining the same humidity. (In this mode, the control system outputs a low control current signal to control the fan speed until it stops, slowing the water pump speed, reducing the amount of liquid entering the system, and maintaining a constant temperature and humidity in the space.)In the cooling mode of the outdoor system, when the indoor temperature and humidity are high, the control system A1 controls the booster pump (the operating frequency becomes higher, the output power becomes larger, and the amount of liquid medium pumped into the surface cooler becomes larger) and the fan (the operating frequency becomes higher, the output power becomes larger, the amount of air sucked in by the negative pressure becomes larger, and the cooling capacity of the air blown out is higher). The operating frequency becomes higher, providing more refrigerant for the surface cooler and the amount of cold air blown out by the fan blades is larger. When the indoor temperature drops and the temperature of the A22 pipe is higher than the dew point temperature (in this mode, the control system outputs a higher control current signal to control the valve core of the first liquid outlet end of the electric proportional valve M1 to open to a large extent, the liquid medium flow entering the transducer is relatively large, and the amount of liquid medium directly output to the return pipe of the outdoor system through the second liquid outlet becomes larger). When the indoor temperature is low and the humidity is low, control system A1 controls the booster pump (which operates at a lower frequency, resulting in lower output power and a smaller amount of liquid pumped into the surface cooler) and the fan (which operates at a lower frequency, resulting in lower output power and a smaller amount of air drawn in by negative pressure, resulting in less cooling air delivered). This reduces the amount of refrigerant supplied to the surface cooler and transducer, and the fan blades deliver a smaller amount of cooling air, causing the indoor temperature and humidity to rise. (In this mode, the control system outputs a low control current signal to slightly open the valve core at the first liquid outlet of electric proportional valve M1, reducing the amount of liquid flowing into the transducer and increasing the amount of liquid delivered directly to the return pipe of the external unit system through the second liquid outlet.) This step prevents the control of indoor temperature and humidity based on data signals from the external unit's temperature and humidity sensors, which can lead to variations in temperature and humidity across different indoor areas. This unified approach cannot effectively adjust the temperature and humidity of each room, hindering user experience.

[0021] Figure 1 、 2 As shown in FIG3 , in step (4), when the indoor unit 1 is working, the external air enters the rear end of the cooler through the ventilation grooves 103 on both sides of the rear end of the shell under the action of the negative pressure generated by the fan F, and the flowing air passes through the plurality of fins at the rear end of the cooler 101 and the front end of the cooler 101 to dissipate heat or cold, and then outputs hot air or cold air to the indoor environment through the filter 104 at the front end of the shell. At the same time, a plurality of ultraviolet sterilization lamps H and a negative ion generator A4 disinfect the air entering the room. In this step, since the fan is installed on the inner side of the V-shaped cooler 101, the cooler 101 plays an enclosed role on the fan M to reduce external noise, and the light of the ultraviolet sterilization lamp H is blocked by the V-shaped cooler to reduce the adverse effects of light leakage on the user's health.

[0022] Figure 1 、 2As shown in Figure 3, through all the above technical solutions, the utility model integrates multiple indoor devices into one, with a compact structure. The indoor and outdoor units installed in each room are connected in parallel through pipes, and the indoor unit and the transducer in each room are connected in series through pipes. During installation, the staff only needs to connect the corresponding two interfaces of the outdoor unit with the two interfaces of the indoor unit, which can achieve quick installation, improve installation speed and efficiency, and save installation costs. Each indoor unit is equipped with a booster pump, and the sensors matched with the control system of each indoor unit can collect the temperature, humidity and pipe temperature of each room in real time. The indoor temperature and humidity data and the flow of the booster pump are accurately adjusted through a one-position two-way proportional valve, which can achieve relatively accurate temperature and humidity control, thereby bringing a more comfortable experience to users in different rooms and achieving energy-saving effects. The fan and ultraviolet sterilization lamp of the indoor unit are installed at the inner end of the V-shaped structure surface cooler, which reduces the noise of the fan, and simultaneously sterilizes and disinfects the two inner ends of the surface cooler, and reduces the adverse effects of ultraviolet leakage on user health. Figure 3 Among them, voltage module A5 is a finished product of AC 220V to DC 24V switching power supply module; PLCA1 model is LK2N-32MR; temperature sensors A21 and A22 are finished products of thermocouple temperature transmitter model SGN-HR, which has two power input terminals and one signal output terminal (output 4-20mA current signal); humidity sensor A3 is a finished product of humidity transmitter model KS-SHTE, which has two power input terminals and one signal output terminal (output 4-20mA current signal); booster pump M is model SHIMGE / 220V The inverter-type booster water pump (120W power) is included. The negative ion generator A4 is a finished product, model KJF03-220V. The electric proportional valve M1 is a finished product, a 5W, one-inlet, two-outlet electric proportional valve with two power inputs and one signal input. Different current signals are input to the control signal inputs, causing the valve core to open and close differently. When one outlet has a high flow rate, the other has a low flow rate. Conversely, when one outlet has a low flow rate, the other has a high flow rate. The fan is a 200W inverter-type small fan. The ultraviolet germicidal lamp H has a power of 20W. These components all utilize existing, mature technologies. This application does not elaborate on their operating principles, nor does it specifically protect their structure and function.
