Description

TECHNICAL FIELD

[0001] The present application relates to a windless air conditioner cooling and heating two combined supply system, belonging to the technical field of air conditioning. BACKGROUND

[0002] Air conditioner is a device that uses artificial means to adjust the temperature, humidity, flow rate and cleanliness of air in a closed space. Air conditioner plays a vital role in people's life, according to the function, there are: single refrigeration type air conditioner, cooling and heating type air conditioner. According to the use scene, there are: wall-mounted air conditioner, ceiling type air conditioner, stand type air conditioner, central air conditioner. In the north, air conditioner is mainly used for cooling in summer, and heating is used in winter. Indoor air conditioning system and heating system are installed, which not only has high installation cost, but also has high use cost; in the south, air conditioner is used for cooling in summer and heating in winter. The existing air conditioner sends the cold or heat generated by the air conditioner into the room through the fan. In the cooling process, strong cold wind is blown into the room, which will make people feel very uncomfortable after a long time. In addition, the existing air conditioner also has the disadvantages of high energy consumption, large working noise and easy breeding of bacteria in the air conditioner.

[0003] With the continuous deepening of ordinary people's understanding of air conditioner products and the continuous improvement of quality demand, air conditioner manufacturers are also continuously developing, and have carried out technical upgrading and iteration in noise, power saving, direct blowing prevention, health sterilization and other aspects. However, the overuse of air conditioner is easy to suffer from "air conditioner disease", which cannot be avoided.

[0004] The floor heating system is the abbreviation of floor radiant heating system, which is composed of heat source, pipeline and auxiliary materials, and forms a temperature gradient from bottom to top by uniform radiation of ground heat, which meets the physiological demand of "warm feet and cool head".

[0005] In recent years, some people have also tried to use floor heating system for refrigeration, but ground condensation has always been a problem in the industry.

[0006] In 2018, Japan launched "Tian Fluorine Di Shui" central air conditioning system, which takes air source heat pump as the core, connects floor heating coil and ceiling type air conditioner, floor heating coil is set under the floor in indoor, ceiling type air conditioner is set on the roof surface in indoor, floor heating coil is connected with air source heat pump water tank, ceiling type air conditioner is connected with refrigerant refrigerant refrigeration pipe for refrigeration. In summer, use air conditioner for refrigeration, in winter, use floor heating coil for heating, air conditioner and floor heating can also work at the same time, which has high energy efficiency. But "Tian Fluorine Di Shui" central air conditioning system still has blowing and a small amount of noise when air conditioner works.

[0007] Patent No. 2021103660145 discloses a cold beam, comprising a cold radiation box and a circulating water pipe. The cold radiation box is a regular closed flat box body, and a circulating water channel is arranged inside the cold radiation box. Two or four circulating water pipe through holes are opened on the main cold radiation surface of the cold radiation box. The number of cold radiation boxes is N+1, and the main cold radiation surfaces of the cold radiation boxes are arranged in parallel and spaced apart. The cold radiation boxes are connected by circulating water pipes corresponding to the number of circulating water pipe through holes on the cold radiation boxes. The circulating water pipe and the circulating water pipe through hole of the cold radiation box are in sealed connection. The pipe section of each circulating water pipe in the cold radiation box is provided with an inlet and outlet water hole. The cold beam is installed at the end of an air conditioning system, and uses water circulation refrigeration and heating. It does not blow wind, has no noise, is quiet and comfortable, and cannot cause air conditioning disease. It overcomes many disadvantages of air-cooled air conditioners. However, the cold radiation efficiency of the cold beam still needs to be improved, and the surface of the cold radiation box will condense condensed water during operation. According to the traditional way, a condensed water collecting box is arranged below the cold beam, and the collected condensed water is discharged by a water pipe. The condensed water collecting box will block the air flow channel below the cold beam for cold and heat exchange with the cold beam, greatly reducing the cold radiation efficiency of the cold beam.

[0008] Patent No. 2021112263332 discloses a cold beam, which improves the structure of the cold beam of Patent No. 2021103660145. In particular, a water collecting groove with a "mountain" shaped cross section is connected to the lower cold radiation wing of each cold radiation box. This solves the problem of Patent No. 2021103660145 that the condensed water collecting box blocks the air flow channel below the cold beam for cold and heat exchange with the cold beam, greatly reducing the cold radiation efficiency of the cold beam. It has very good dehumidification effect. However, this patent still has the problem of slow room temperature adjustment speed, which affects the comfort of the room. SUMMARY

[0009] The purpose of the present application is to provide a windless air conditioning and heating two combined supply system with fast temperature adjustment speed, comfortable and quiet use, good dehumidification effect, no ground dew, high energy efficiency and good energy saving effect.

[0010] In order to achieve the above purpose, the technical scheme adopted by the present application is as follows: The application discloses a windless air conditioner cold and warm two combined supply system, which comprises an air source heat pump, a buffer water tank, a floor heating coil and a dehumidification cold beam, wherein the buffer water tank is connected with the air source heat pump through a liquid conveying pipeline, a floor heating water collector and a water power distributor are respectively connected to a heat medium output circulation pipeline of the buffer water tank, each group of interfaces of the floor heating water collector is connected with a floor heating coil, and each interface of the water power distributor is connected with a dehumidification cold beam; the air source heat pump is installed outdoors, at least one floor heating coil is arranged under the floor of each room indoors, and at least one dehumidification cold beam is installed on the roof of each room; indoor temperature regulation is realized by uniformly setting the heating or refrigeration of the air source heat pump on the heat medium, and the driving pump of the buffer water tank drives the heat medium to circulate in the floor heating coil and the dehumidification cold beam, so that the cold or heat of the rooms is simultaneously released to regulate the temperature and humidity.

[0011] The dehumidification cold beam comprises a cooling box and a circulating water pipe, the cooling box is a long strip closed flat box body, the cross section of the cooling box is a rectangle with an obtuse angle chamfer or an ellipse; a transverse support rib is arranged in the cooling box along the length direction, and cooling wings are arranged on the outer top ends of two opposite arc surfaces of the cooling box along the length direction; two circulating water pipe through holes are respectively formed at the two ends of the vertical surface of the cooling box, two circulating water pipes are respectively passed through the corresponding circulating water pipe through holes of the cooling box, all the cooling boxes are fixedly connected, the circulating water pipe and the cooling box are in sealed connection, one of the two circulating water pipes is a water inlet pipe and the other is a water return pipe, and circulating water holes are formed on the pipe sections of each circulating water pipe in the cooling box; a water receiving strip groove with a cross section in the shape of a "mountain" is connected to the lower cooling wing of each cooling box, the middle vertical edge of the water receiving strip groove is connected with the cooling wing, the width of the water receiving strip groove is less than or equal to the thickness of the cooling box, and the length of the water receiving strip groove is greater than or equal to the length of the cooling box, water receiving boxes are arranged at the two ends of the water receiving strip groove, and the ends of all the water receiving strip grooves are inserted into the corresponding water receiving boxes.

[0012] The heat medium is water, alcohol or refrigerant.

[0013] The heating temperature of the air source heat pump on the heat medium is controlled to be 30-45 DEG C.

[0014] The refrigeration temperature of the air source heat pump on the heat medium is controlled to be 16-23 DEG C.

[0015] The buffer water tank is connected with multiple dehumidification cold beams through the water power distributor.

[0016] The temperature in each room can be controlled and adjusted by adjusting the valve flow opening degree of the corresponding floor heating coil interface of the floor heating water collector.

[0017] The beneficial effects of the present application are: the present application innovatively integrates three core technologies of high-efficiency energy supply of heat pump, comfortable temperature control of ground radiation, and precise humidity management of dehumidification cold beam, successfully breaks through the energy efficiency limitation of traditional air conditioning systems, realizes low-energy-consumption high-efficiency energy supply, runs without noise and air blowing, is comfortable to use, has fast temperature adjustment speed, good dehumidification effect, and no dew formation on the ground during the refrigeration process. When refrigerating in summer, the temperature of the circulating cool water in the ground heating module pipeline is the same as that of the circulating cool water in the dehumidification cold beam, the surface temperature of the dehumidification cold beam is basically the same as the temperature of the cool water, and the ground surface temperature is about 5° higher than the temperature of the cool water. This is because the ground heating coil is laid about 5cm below the ground surface, and the cold energy in the ground heating coil gradually attenuates due to the thermal resistance of the ground backfill layer and the floor tiles. When the dew point temperature of indoor air reaches the surface temperature of the cold beam, the cold beam starts to dehumidify, and the humidity of indoor air is always controlled within a certain range. Since the surface temperature of the cold beam is always about 5° lower than the ground surface temperature, the cold beam dew formation and the ground surface dew formation do not occur.

[0023] The application adopts the innovative mode of heat pump + ground radiation + dehumidification cold beam, and builds the golden triangle of building efficient cooling and heating dehumidification.

[0024] I. Heat Pump: The core power source driving efficient cold and heat sources.

[0025] Heat pump technology extracts low-grade heat (or cold) from the air, soil, or water by consuming a small amount of electricity and converts it into high-grade heat (or cold) usable in buildings. Its significant advantage lies in its coefficient of performance (COP), which far exceeds that of traditional electric heating or gas-fired boilers. Winter heating: Air source heat pumps can achieve a COP of 3 to 4, meaning that for every unit of electricity consumed, 3 to 4 units of heat can be provided.

[0026] Summer cooling: The cooling energy efficiency ratio (EER) is significantly better than that of traditional split air conditioners.

[0027] As the core component of the system, the air source heat pump lays the foundation for high energy efficiency and low cost operation of the entire technical solution.

[0028] II. Radiant floor heating system consisting of underfloor heating pipes: a model of low temperature difference and high-comfort heat transfer.

[0029] Radiant floor heating / cooling systems release heat or cold energy by circulating a heat transfer medium through underfloor heating coils and pipes laid within the floor, utilizing large-area radiant heat transfer to regulate indoor temperature. Heating advantages: The lower supply water temperature of only 30-45°C perfectly matches the optimal energy efficiency of air source heat pumps operating at low condensing temperatures. Compared to the 60-80°C high-temperature water required by traditional radiators, this significantly reduces heat pump energy consumption.

[0030] Cooling advantages: Using relatively high-temperature chilled water (16-23°C) reduces the risk of condensation on pipe surfaces in summer and avoids direct cold air blowing. In dry northwest regions, it can also increase indoor relative humidity and enhance comfort.

[0031] Thermal comfort: Uniform radiant heat exchange brings a comfortable feeling of "warm but not dry" (heating) and "cool but no wind" (cooling), without the feeling of draft or noise interference.

[0032] 3. Dehumidifying and cooling beams: Provides winter and summer adjustment to ensure comfort and energy saving.

[0033] In the system of this invention, the dehumidifying beam mainly undertakes the task of dehumidification in summer, ensuring that condensation does not occur during ground cooling: 1. Dehumidification principle: The surface temperature of the cold beam is lower than the indoor dew point temperature, causing water vapor in the indoor hot air to condense upon contact with the cold air, transforming it into dry and cold air and forming a convection circulation, thus achieving whole-house dehumidification and cooling.

[0034] 2. Synergistic Mechanism: The underfloor heating pipes and the roof dehumidification beams circulate low-temperature cold water synchronously. The floor temperature is about 5°C higher than the cold water temperature and is also higher than the air dew point temperature, thus eliminating condensation on the floor at the source.

[0035] 3. Energy-saving advantages: High water temperature cooling: Using higher temperature cold water can meet the cooling demand, greatly improving the COP of the chiller (higher evaporation temperature).

[0036] No fan energy consumption: Passive cooling beam relies on natural convection to operate, with no fan energy consumption, and operates quietly and without disturbance.

[0037] Four, synergy of the golden triangle: release energy efficiency multiplication potential.

[0038] Organic combination of heat pump, ground radiation, and dehumidification cooling beam, giving birth to energy efficiency advantages far beyond single system: 1. Maximize heat pump efficiency: Winter heating: The low-temperature hot water (30-45°C) required by the ground radiation system allows the heat pump to always operate in the highest COP range.

[0039] Summer cooling: Both the dehumidification cooling beam and the ground radiation system can use higher temperature cold water of 16-23°C, significantly improving the evaporation temperature of the chiller. Compared with the 7°C chilled water required by traditional systems, energy consumption can be reduced by 30-40%.

[0040] 2. Improve comfort and health: No blowing feeling: The combination of radiant heat transfer and natural convection of the cooling beam achieves a top-level comfortable experience with uniform temperature and constant humidity.

[0041] Quality ventilation: Supports window ventilation to ensure adequate indoor ventilation and effectively improves air quality (IAQ).

[0042] 3. Significantly reduce operating costs: The high efficiency of the heat pump itself, combined with its operation in more optimal conditions (high evaporation temperature / low condensation temperature), and the system's avoidance of energy waste such as reheating, make the overall system's annual comprehensive energy efficiency ratio (SCOP) reach an extremely high level, greatly reducing operating costs.

[0043] Five, real test data and engineering practice verification: Laboratory test: The test site is located in Qingshan District, Baotou City, Inner Mongolia, with a room height of 3 meters, a building area of 90 square meters, and general insulation conditions. During the summer cooling period (June 15-September 15, 2024), the system was continuously operated for 24 hours, with the indoor temperature set at 26°C. The test results show: Total electricity consumption is only 1084 degrees, with electricity bill expenditure of 450 yuan; The relative humidity of indoor air is stably maintained at 45%, while the outdoor humidity is 35%, and the indoor comfort level is extremely high; Even in the rain, the maximum humidity outside, open the door and window ventilation 1 hour, the radiant cooling floor still did not appear dew point phenomenon.

[0044] Engineering applications: The system of the present application has been running stably in the laboratory of the applicant's company for three and a half years, and has been running continuously in the experience store for two years. No failure or abnormality has occurred during the operation, which fully verifies its reliability and stability, and provides a strong guarantee for large-scale popularization and application.

[0045] Six, technical innovation and core advantage 1. High efficiency and energy saving: Compared with traditional air conditioning systems, the energy utilization efficiency is greatly improved, the energy saving effect is more than 50%, and the energy consumption and operation cost are significantly reduced.

[0046] 2. Environmental protection and health: Reduce greenhouse gas emissions, help environmental protection; Improve indoor air quality, maintain appropriate humidity, and benefit human health.

[0047] 3. Intelligent control: Take advantage of the temperature difference between the dehumidification cold beam and the radiant cooling floor to realize intelligent and precise control of the cold beam natural dehumidification and the radiant cooling floor, and improve user experience.

[0048] 4. Innovation integration: Ingenious integration of dehumidification cold beam and radiant cooling floor system, fully play the advantages of radiant cooling floor, break through the bottleneck of traditional technology.

[0049] Comparison with similar technologies at home and abroad:

[0050] In summary, the wind-free heating and cooling air conditioning two combined supply system of the present application successfully breaks through the energy efficiency bottleneck of traditional air conditioning systems by innovatively integrating heat pump, radiant cooling floor and dehumidification cold beam three core technologies, and realizes the dual goals of high efficiency and comfort and health. After laboratory testing and engineering application verification, the system shows excellent energy efficiency, reliability and comfort, and has the conditions for large-scale popularization and application. In the future, the system is expected to be widely used in high-end residential buildings, office buildings, hospitals, schools and other places.
