Description

Technical Field

[0001] The invention relates to an air conditioner, and in particular to a fresh cold air manufacturing system. Background Art

[0002] With the development of society, air conditioners are used more and more frequently and are also a necessity in people's lives. Their temperature adjustment function is loved by everyone. Of course, with the improvement of the quality of life, users' requirements for air conditioners are getting higher and higher. Now the air quality in life is getting worse and worse. If the air conditioner can also purify the air, it will be favored by more users. Therefore, how to improve the ability of air conditioners to purify the air is the focus of research and development.

[0003] In the prior art, an air conditioning system (which may be a central household air conditioner or a general household desktop air conditioner, etc.) includes: a compressor, a four-way valve, a condenser, a capillary tube, an indoor evaporator and an indoor fan. A first channel and a second channel are provided in the indoor evaporator. The first channel is for refrigerant liquid to pass through, and the second channel is for air to pass through. The compressor is connected to the first channel through the four-way valve, the condenser and the capillary tube, and the second channel is connected to the indoor fan.

[0004] The working principle of the above air-conditioning system is as follows: first, the refrigerant liquid is compressed into high temperature and high pressure in the compressor and passes through the four-way valve; then, the condenser dissipates heat; followed by the capillary tube reducing the pressure; then, the refrigerant liquid that has dissipated heat and reduced pressure enters the indoor evaporator for evaporation, and the refrigerant liquid exchanges heat with the air in the indoor evaporator to achieve cooling of the air; finally, the indoor fan blows the refrigerated gas evaporated by the indoor evaporator into the room to lower the indoor temperature.

[0005] Although the above air conditioning system has good cooling effect, it still has the following disadvantages:

[0006] Disadvantage 1: The evaporated low-toxic cold gas is directly blown into the room, causing indoor air pollution;

[0007] Disadvantage 2: The power consumption is very high. For the same 3P power appliances, the power consumption of an air conditioning system is 20% higher than that of other appliances. In order to maintain the indoor temperature, the air conditioner keeps running to cool down. The air conditioner keeps running to increase the power consumption. The higher the power consumption, the higher the energy displacement, and the more serious the pollution to the environment.

[0008] Disadvantage 3: Based on disadvantage 2, in order to save energy and reduce emissions, people close indoor doors and windows, so it is impossible to introduce fresh air from outdoor into indoor areas. The indoor areas cannot be replenished with fresh air, and building decoration materials emit carbon monoxide and carbon dioxide, and air conditioners emit low-toxic cooling liquids, which cannot be removed in time, causing indoor air pollution to worsen. People live and work in low-toxic air-conditioned rooms for a long time, breathing polluted air for a long time, which reduces people's immunity. Over time, it leads to cervical spondylosis, vascular involvement, neck pain, etc., causing most people to suffer from sub-health diseases.

[0009] The Chinese patent discloses a method and device for air cooling and power generation with application number CN201910321202.9. The method includes setting a heat exchanger that uses cold water to cool the air, and the heat exchanger is placed at the bottom of the low-temperature water; an isolation box or isolation pool is set around the heat exchanger at a certain height from the water surface to isolate the water body around the heat exchanger at a certain depth below the water surface from other water bodies, and a water inlet is opened on the side of the bottom of the isolation box or isolation pool, and a hydro-generator is installed at the water inlet, and the thrust of the cold water entering the isolation box or isolation pool is used to generate electricity. Although this method can achieve energy-saving power generation to a certain extent, this method uses the power generation technology of water conservancy engineering principles to provide energy. From the perspective of water conservancy engineering power generation technology, water conservancy power generation must meet two conditions: 1. Adequate water source, 2. Good drainage of elevation drop. Only when the water pressure and flow rate are stable can the speed of the water wheel be driven stably. When the speed is stable, the generator can also generate electricity stably. To ensure the normal operation of an existing 3P air conditioner, a 4KW generator is required. The actual efficiency of the generator is 80%. 80%*4KW=3.2KW can meet the electricity consumption of the 3P air conditioner. The technical design uses an isolation box or isolation pool to store water as the water source, and a hydro-generator is installed at the water inlet. The water source is insufficient, the elevation difference is insufficient, and the water pressure and flow rate are insufficient. The water wheel cannot be driven to drive the generator to generate electricity normally. The water fee is more expensive than the electricity fee, and the power generation conditions of the water conservancy project cannot be met. The technical design is unreasonable, the cost is high, and it is not economical and practical and cannot be promoted and applied. Summary of the invention

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and functions achieved by the present invention clearer and easier to understand, the present invention is further explained below in conjunction with the accompanying drawings and specific implementation methods.

[0034] Embodiment 1:

[0035] like Figure 1 as well as Figure 2 As shown, the present invention proposes a fresh cold air manufacturing system, including: an air intake system, which includes: a refrigeration box 11, an air intake fan 12, a first filter 13, a refrigerant pipe 14 and an air supply fan, the air intake end of the refrigeration box 11 is installed with an air intake fan 12, and the first filter 13 is installed in the middle of the refrigeration box 11. The first filter 13 is used to filter the air from the air intake end to the air outlet end of the refrigeration box 11, and a refrigerant pipe 14 is installed in the middle of the refrigeration box 11. The refrigerant pipe 14 surrounds the refrigeration cavity set in the refrigeration box 11, and an air supply fan is installed at the air outlet end of the refrigeration box 11; an intermediate pipe 3, one end of which is connected to the air outlet end of the refrigeration box 11; an indoor air conditioner 4, the other end of the intermediate pipe 3 is connected to the input end of the indoor air conditioner 4; and a refrigerant condensation transport system, whose water inlet and water outlet are respectively connected to the two ends of the refrigerant pipe 14, and the refrigerant condensation transport system is used to circulate and transport the refrigerant.

[0036] In order to form a stable heat exchange environment and facilitate filtering, a first partition block 111 and a second partition block 112 are installed in the refrigeration box body 11 to form a refrigeration cavity between the first partition block 111 and the second partition block 112. The second partition block 112 is located on the side of the first partition block 111 close to the air outlet end. A through hole connecting the refrigeration cavity is opened on the second partition block 112, and the refrigerant pipe 14 surrounds the outside of the refrigeration cavity.

[0037] A cylindrical third filter 52 is installed in the refrigeration cavity, and the third filter 52 divides the refrigeration cavity into an inner cavity and an outer cavity. The outer cavity is connected to the refrigerant pipe 14, and an air guide duct 2 and a third baffle block 113 are installed in the refrigeration box body 11. The air guide duct 2 extends into the inner cavity. The first filter 13 is installed at the air inlet end of the refrigeration box body 11. The third baffle block 113 is located on the side of the first baffle block 111 away from the second baffle block 112. The air inlet end of the air guide duct 2 passes through the third baffle block 113, and the suction fan 12 is installed at the air inlet end of the air guide duct 2.

[0038] In order to facilitate the installation of the intake fan 12 and prevent the intake fan 12 from being too large and causing the air duct 2 to be easily broken, the air duct 2 and the third partition block 113 are installed in the refrigeration box body 11. The third partition block 113 is located on the side of the first partition block 111 away from the second partition block 112. The air inlet end of the air duct 2 passes through the third partition block 113, and the intake fan 12 is installed at the air inlet end of the air duct 2. The air inlet end of the air duct 2 extends into the first filter 13.

[0039] In order to prevent the air flow from flowing back, a one-way valve is installed at the air inlet end of the air guide duct 2. The one-way valve is located between the first baffle block 111 and the third baffle block 113. The one-way valve prevents air from flowing from the first baffle block 111 to the third baffle block 113.

[0040] In order to design an air guide duct 2 with a simple structure, extend the air path in the refrigeration chamber, and also increase a certain contact area, so as to achieve better heat exchange effect and better refrigeration effect, the air guide duct 2 includes: an air guide cover 21, a main pipe 22, a connecting plate 23, a branch pipe 24 and a cache pipe 25. The air guide cover 21 is installed with an air intake fan 12. The air guide cover 21 is a horn structure. The small end of the air guide cover 21 is connected to the main pipe 22. The main pipe 22 is connected to multiple branch pipes 24 through the connecting plate 23. All branch pipes 24 are connected to a cache pipe 25. The end of the cache pipe 25 away from the branch pipe 24 passes through the second blocking block 112 through a through hole.

[0041] An end of the third filter 52 close to the exhaust hole is a blocking end.

[0042] In order to avoid excessive pressure at the air supply fan, a wind pressure sensor 6 is installed between the air supply fan and the intermediate pipe 3 , and the wind pressure sensor 6 is located in the refrigeration box 11 .

[0043] The indoor air conditioner 4 includes: an air supply shell, an indoor fan and a second filter 41. The input end of the air supply shell is connected to the intermediate pipe 3, and the output end of the air supply shell is connected to the room. A second filter 41 is installed in the air supply shell. The second filter 41 is used to purify the air discharged from the output end of the air supply shell. An indoor fan is installed in the air supply shell, and the indoor fan directly supplies air to the room.

[0044] A fourth filter 42 is installed on the outer wall of the air supply housing. The fourth filter 42 is an indoor grid activated carbon filter, which is used to absorb and filter indoor formaldehyde, carbon dioxide and cold air pollutants.

[0045] In the above structure, first, the suction fan absorbs outdoor air and sends it into the refrigeration chamber for refrigeration. During this process, the air passes through the first filter 13. The first filter 13 adopts a bamboo fiber air filter. The bamboo fiber air filter filters outdoor air pollutants such as bacteria and dust. The air passes through a one-way valve. The function of the one-way valve is: one-way ventilation. The refrigerant condensation and delivery system cools the refrigerant and drives it in a circulation manner, so that the refrigerant can enter the refrigerant pipeline 14; then, the branch pipe 24 and the cache pipe 25 are made of copper pipes. Copper is not easy to rust and has good thermal conductivity. Therefore, heat exchange can be quickly achieved to achieve the refrigeration function. The air in the branch pipe 24 exchanges heat with the entire environment for refrigeration, and then is sent to the cache pipe 25 for caching and heat preservation. During the entire refrigeration process, since the branch pipe 24 and the cache pipe 25 are bathed in the refrigerant, refrigeration can be quickly achieved, thereby improving the refrigeration effect. The third filter 52 (the third filter 52 is an activated carbon quartz sand filter. The activated carbon quartz sand filter is used to adsorb and filter bacteria, pollutants, low-toxic liquid substances, etc. in the water to improve the water quality). In order to prevent scale and other impurities from being deposited in the branch pipe 24 and the buffer pipe 25 and to prevent scale and other impurities from affecting the heat exchange effect, it is ensured that the refrigerant can exchange heat with the buffer pipe 25 and the air in the branch pipe 24; then, the refrigerated and purified air enters the indoor air conditioner 4 with the help of the air supply fan; finally, a second filter 41 is provided in the indoor air conditioner 4, and the second filter 41 is an indoor grid activated carbon filter, which is used to adsorb and filter indoor formaldehyde, carbon dioxide and cold air pollutants, and also to prevent the air from being polluted again due to impurities in the pipeline after passing through the first filter 13.

[0046] The refrigerant condensation and transportation system includes: a condenser 53, a condensing fan 54, a compressor 55 and a four-way valve 56. The condenser 53 is used to condense the refrigerant. The condensing fan 54 is installed at the condenser 53. One end of the compressor 55 is connected to one end of the refrigerant pipeline 14. The other end of the compressor 55 is connected to the condenser 53 through the four-way valve 56. The condenser 53 is connected to the other end of the refrigerant pipeline 14.

[0047] The effects that can be achieved by this application are: economical and practical, energy-saving, low-displacement, low-energy consumption, high-quality and fresh cold air. Specifically, the following effects are included: First, a first filter 13 is set in the middle of the refrigeration box 11. The first filter 13 uses bamboo fiber as an air filter to filter pollutants and dust in the air; second, the refrigerant in the refrigeration chamber is circulated by the condenser 53, the compressor 55, etc., the third filter 52 filters the refrigerant, the rapid refrigeration branch pipe 24 and the cache pipe 25, and the cache pipe 25 constitutes a multifunctional body outside, which has the function of absorbing bacteria, pollutants, and liquids in the refrigerant, and has the function of isolating and refrigerating the air. After the outdoor air is sucked in by the suction fan 12 filter, the air is introduced into The branch pipe 24 is isolated and refrigerated, and then introduced into the buffer pipe 25 for air storage and heat preservation. The cold air is exhausted by the indoor fan and filtered through the activated carbon filter (that is, the second filter 41), and fresh and pollution-free cold air is blown into the room. A temperature sensor is installed indoors to check the indoor temperature. When the indoor temperature reaches the set temperature value, the sensor sends a command to the control system to intelligently control the exhaust speed of the exhaust fan. A pressure sensor is installed at the output air pipe of the air storage chamber to detect the pressure of the air storage chamber. When the pressure of the air storage chamber rises to the set value, the sensor sends a command to the system to control the air supply speed of the air intake fan to reduce the air intake. The refrigeration box 11 is cast into a long round structure using aluminum profiles. Aluminum is not easy to rust, light in weight, and simple to process. A water temperature sensor is installed in the refrigeration box 11 to detect the water temperature. When the water temperature reaches the set refrigeration temperature value, an instruction is issued to the system to control the compressor 55 to stop refrigeration. The water level sensor detects the water level. When the water level is lower than the sensor, water is automatically replenished. The refrigeration box 11 is packed with thermal insulation cotton to make the water temperature in the refrigeration box 11 constant and lasting, reducing the working time of the compressor 55, thereby achieving the purpose of energy saving and electricity consumption. The compressor 55 compresses the refrigerant liquid into high pressure and high temperature, which is converted by the four-way valve 56 and introduced into the condenser 53 for cooling by the fan, and then sent to the dryer for filtration, depressurized by the capillary, and introduced into the carbon refrigerant pipeline 14 wrapped around the activated carbon quartz sand filter for refrigeration.The compressor 55, the condensing fan 54, the air supply fan and the air suction fan 12 use low-voltage 24V direct current to supply the working energy of the machine. It can be powered by solar energy or city electricity. Just select the city electricity or solar energy button on the remote control, and the system will automatically switch to the city electricity or solar energy power supply mode. The activated carbon quartz sand forms a comprehensive multifunctional third filter 52. The heat exchanger evaporation tube (that is, the refrigerant pipeline 14) is wound outside the activated carbon quartz sand filter. The activated carbon quartz sand filter absorbs the low-toxic refrigerant liquid evaporated by the heat exchanger and filters the pollutants in the water to purify the water quality. The gas copper pipe and the air storage chamber isolate the air for refrigeration. The refrigeration cavity has a small volume, a small water capacity, and a fast refrigeration, which reduces the refrigeration working time of the compressor 55. The outer shell of the refrigeration box 11 is packed with thermal insulation cotton to keep the water temperature of the refrigeration cavity constant at minus 5 degrees. The cooling fan of the compressor 55 is always in a stopped state. The outdoor air is filtered by bamboo fiber and isolated by copper pipes. The activated carbon quartz sand absorbs and filters pollutants, and finally forms pollution-free fresh cold air.

[0048] Compared with the energy saving of the existing air conditioner and central air conditioner, the technology of the present invention consumes 2.78 degrees of electricity per hour of the existing 3P air conditioner when it works for eight hours. 8 hours*2.78 degrees / hour=22.24 degrees, and 22.24 degrees of electricity are consumed in eight hours.

[0049] The refrigeration chamber of the present invention has a small volume, a small water capacity, and a fast refrigeration. A 1P compressor with a power of 55W is used for sufficient refrigeration. The power of the air supply fan and the air intake fan is 80W respectively. The refrigeration chamber of the present invention is designed to have a small volume and a small water capacity, and the water temperature in the water chamber can be quickly cooled to minus 5 degrees in 30 minutes. The cavity is packed with thermal insulation cotton to keep the water temperature below zero. The compressor 55 and the cooling fan are in a shutdown state. Only the air supply fan and the air intake fan work for eight hours a day. The power of the air intake fan and the air supply fan is 120W in total, and the power consumption per hour is 0.12 degrees. 8 hours*0.12 degrees / hour=0.96 degrees. 0.96 kWh + 1.04 kWh of other working electricity (for example: the power consumption of the compressor 55 and the cooling fan for eight hours) = 2.5 kWh. The experimental results show that the technology of the present invention consumes a total of 2.5 kWh of electricity in eight hours of refrigeration. Compared with the existing air conditioner, the existing air conditioner consumes 22.24 kWh of electricity in eight hours, and the technology of the present invention consumes 2.5 kWh of electricity in eight hours. 22.24 is compared with 2.5. The technology of the present invention can save 19.74 kWh of electricity in eight hours of refrigeration. If a city has one million users, the energy saving can reach 85% of energy saving and emission reduction. The manufacturing and processing are simple, economical and practical.

[0050] In this embodiment, firstly, a first filter 13 is installed at the air inlet end of the refrigeration box 11, so that the air is filtered before entering the subsequent pipeline, which avoids excessive deposition of impurities in the subsequent pipeline and causes pipeline blockage or air pollution after the pipeline is used many times, thereby ensuring the effect of fresh air; then, heat exchange is realized in the middle of the refrigeration box 11, and the length of the air guide is set to ensure the heat exchange time, thereby ensuring that the air temperature obtained after the heat exchange is required, thereby reducing the energy consumption required in this process; furthermore, a third filter 52 is set to filter the refrigerant, It avoids the deposition of impurities such as scale outside the air guide duct 2, and avoids the deposition of impurities such as scale that leads to poor heat exchange effect, thereby further ensuring the heat exchange effect; then, a second filter 41 is arranged in the indoor air conditioner 4 to realize air filtration again, thereby avoiding the air passing through the first filter 13 from being contaminated by the pipeline again, thereby ensuring that the air out is fresh air; finally, the dual refrigeration of the refrigeration box 11 and the indoor air conditioner 4, the front end and the rear end cooperate with each other, the front end refrigerant can be cold water, etc., and the front end refrigeration box 11 preliminarily cools the air, thereby achieving a refrigeration effect and saving energy.

[0051] Embodiment 2:

[0052] like Figure 3 as well as Figure 4 As shown, this embodiment makes the following changes on the basis of the embodiment 1: the internal structure of the cache tube 25. Other structures remain unchanged.

[0053] A fifth filter 251 is provided in the cache tube 25. The fifth filter 251 is an annular structure. The fifth filter 251 divides the cache tube 25 into a central cavity and an outer annular cavity. The central cavity is connected to the branch pipe 24. A connecting pipe is installed on the second blocking block 112, and the connecting pipe connects the outer annular cavity.

[0054] The inner wall of the cache tube 25 and the fifth filter 251 work so that the end of the central cavity is connected to the outer annular cavity, that is, when the air rushes into the central cavity from the branch pipe 24, the air rushes to the inner wall of the cache tube 25 away from the branch pipe 24. The inner wall of the cache tube 25 away from the branch pipe 24 is formed with an arc surface 250, and the arc surface 250 protrudes in the direction of the branch pipe 24. The air is rebounded by the arc surface 250. The design of the arc surface 250 disperses the air from the branch pipe 24, and the air rushes to the fifth filter 251. The fifth filter 251 adopts an air fiber fine filter to prevent the air from being rebounded by the inner wall of the planar cache tube 25 and the air in the cache tube 25 affecting the air entering the branch pipe 24. The arc surface 250 also has a divergent effect, so that the air flows toward the side wall of the fifth filter 251, ensuring the smoothness of the air flow, and also extending the flow path of the air in the cache tube 25, thereby improving the heat exchange effect and reducing the use of energy.

[0055] In the present embodiment, firstly, in order to filter the air in the cache tube 25 and further improve the effect of fresh air, a fifth filter 251 is designed; then, in order to extend the air travel path, the cache tube 25 is designed to be a strip structure; then, in order to match the shape of the cache tube 25 and to ensure the filtering effect, the fifth filter 251 is designed to be an annular structure, so that the air entering the cache tube 25 will not directly rush to the fifth filter 251, and the impact of the air on the fifth filter 251 is small, thereby avoiding excessive impact and causing the air to continue to carry away some air pollutants; finally, in order to prevent the air from directly rushing to the branch pipe 24 and affecting the air entering the cache tube 25, a curved surface 250 is designed to allow the air to diverge to the side wall of the fifth filter 251, thereby extending the air travel path without affecting the air intake of the cache tube 25, improving the heat exchange effect, reducing energy consumption, and being beneficial to environmental protection.

[0056] Embodiment 3:

[0057] This embodiment makes the following changes on the basis of Embodiment 1 and Embodiment 2: the installation method of the pressure sensor and the installation method of the intermediate pipe 3 and the refrigeration box 11. This embodiment can be combined with Embodiment 1 or Embodiment 2, and other structures remain unchanged.

[0058] like Figure 5 as well as Figure 6 As shown, in order to realize the installation of the wind pressure sensor 6 , the wind pressure sensor 6 is installed on the end cover 114 of the refrigeration box body 11 through the mounting seat 63 .

[0059] In order to realize the installation of the intermediate pipe 3 and the refrigeration box 11, a first flange 30 is installed at one end of the intermediate pipe 3, and a second flange 110 is installed on the outer wall of the refrigeration box 11. The first flange 30 is connected to the second flange 110 by screws.

[0060] In order to avoid forgetting to install the wind pressure sensor 6, a blocking rod 61 is installed at the connection between the second flange 110 and the refrigeration box body 11. The blocking rod 61 is installed on the refrigeration box body 11 through an elastic member 62. The blocking rod 61 can move relative to the refrigeration box body 11 in a direction parallel to the center line of the refrigeration box body 11. The blocking rod 61 is inserted into the socket opened in the second flange 110. Under the elastic force of the elastic member 62, the blocking rod 61 can be kept misaligned with the socket. The blocking rod 61 acts on a pin 64, and the pin 64 is fixed to the mounting seat 63. The pin 64 is used to push the blocking rod 61 to align with the socket.

[0061] When the end cover 114 is covered on the refrigeration box body 11, if the wind pressure sensor 6 has been installed, the pin 64 pushes the blocking rod 61 to move, so that the blocking rod 61 is aligned with the insertion hole.

[0062] When the end cover 114 is covered on the refrigeration box body 11, if there is no wind pressure sensor 6, there is no component to push the blocking rod 61 to move, making it difficult to align the refrigeration box body 11 and the second flange 110, thereby avoiding the situation where the wind pressure sensor 6 is missing before leaving the factory.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
