Description

Technical Field

[0001] The invention relates to the technical field of outdoor air-conditioning boxes, and in particular to an outdoor energy-saving box for a heating, ventilation and air-conditioning system. Background Art

[0002] With the rapid development of modern buildings and the improvement of people's living standards, the outdoor chassis of the air-conditioning system, as an important part of the HVAC system, is equipped with key components such as compressors, condensers, fans, etc., which are responsible for the exchange of indoor and outdoor heat and maintain the normal operation of the air-conditioning system.

[0003] The principle of air conditioning heating is to move outdoor heat indoors through the second law of thermodynamics. The compressor first compresses the gaseous Freon into a high-temperature and high-pressure gas, and then liquefies it and releases heat through the condenser of the indoor unit, thereby raising the indoor temperature. The liquid Freon is decompressed through the throttling device and enters the heat exchanger of the outdoor unit to evaporate and absorb heat, and then circulates back to achieve the purpose of heating. When the outdoor temperature is very low, especially around zero degrees, the temperature of the heat exchanger in the outdoor unit is lower than the dew point temperature of the outside air, causing the water vapor in the air to freeze and form a frost layer on the heat exchanger, affecting the heat exchange of the heat exchanger. At this time, the air conditioner will automatically start the defrost mode, and the air conditioner control system reverses the flow direction of the refrigerant to increase the surface temperature of the heat exchanger of the outdoor unit, thereby achieving the purpose of melting the frost layer.

[0004] However, this design of air conditioner defrosting will cause the air conditioner to frequently start the defrost mode in an environment of high humidity and low temperature, resulting in unstable indoor temperature and affecting the comfort of indoor users. At the same time, the frost layer melts to form moisture. In a low temperature environment, the drainage system of the outdoor unit will be blocked by ice, resulting in the inability to discharge moisture normally and accumulation, which will further increase the air humidity in the outdoor chassis and aggravate the frosting of subsequent radiator use.

[0035] The second liquid guide tube 31 is connected to the copper flexible liquid tube 33, and the second liquid guide tube 31 is connected to the first liquid guide tube 222 through the copper flexible liquid tube 33.

[0040] Working principle: In actual use, the air conditioner is heated first. After the air conditioner is heated, the refrigerant with a temperature lower than the external environment will enter the second liquid guide tube 31 through the liquid inlet end of the second liquid guide tube 31, and then flow into the first liquid guide tube 222 through the copper flexible liquid tube 33. The flow of refrigerant will transfer the temperature to the second heat sink fin 32 and the first heat sink fin 221, mainly through the second heat sink fin 32 and the first liquid guide tube 222 to increase the contact area with the air, and cooperate with the airflow generated by the servo motor 16 starting to drive the fan part 15 to rotate, so as to heat the refrigerant, and then the refrigerant will be discharged from the discharge port of the second liquid guide tube 31 back to the air conditioning system;

[0041] When the servo motor 16 is started, the working end of the servo motor 16 drives the synchronous gear 1 21 to rotate, and then drives the lower horizontal shaft 23 to rotate through the synchronous belt 22. The rotation of the lower horizontal shaft 23 drives the input end of the centrifugal clutch 24 to rotate. When the speed of the input end of the centrifugal clutch 24 is low, the input end of the centrifugal clutch 24 will not drive the output end to rotate. When the speed is low, it means that the heating power of the air conditioner is low at this time. When the heating power is low, it is not easy to frost on the heat sink fin 2 32 and the liquid guide tube 1 222. When the heating power of the air conditioner is high, In order to ensure the heat exchange efficiency, the working end of the servo motor 16 will rotate at a high speed, and then the high-speed rotating input end of the centrifugal clutch 24 will drive the output end of the centrifugal clutch 24 to rotate. The centrifugal clutch 24 is a prior art device, and the specific working principle is not repeated in the text. The bevel gear 1 25 will be driven to rotate, and then the input end of the planetary gear reducer 29 will be driven to rotate through the bevel gear 27 and the long transmission rod in the shaft frame body 28. After the planetary gear reducer 29 is decelerated, the output end of the planetary gear reducer 29 drives the middle gear member 210 The gear 210 will rotate at a low speed, and then the middle gear 210 will drive the lower gear 211 and the upper gear 2111 to rotate together. The rotation of the lower gear 211 will drive the bottom shaft 214 of the fin to rotate. The rotation of the bottom shaft 214 of the fin drives the horizontal reciprocating wire rod 215 to rotate. The rotation of the horizontal reciprocating wire rod 215 will cause the moving frame 216 connected by the nut pair to move back and forth on the horizontal reciprocating wire rod 215 through its structure. When the moving frame 216 moves to the left, it drives the connected heat sink fin 1 221, and then the heat sink fin 1 221 will move with the heat sink fin 221. The cleaning fin pieces 220 are in staggered contact, and half of the frost on the heat dissipation fin 1 221 will be scraped off when in contact. When the movable frame 216 moves to the right, the heat dissipation fin 1 221 and the cleaning fin piece 1 218 are in staggered contact, and the cleaning fin piece 1 218 will scrape off the remaining half of the frost, thereby achieving the purpose of defrosting the heat dissipation fin 1 221. After the heat dissipation fin 1 221 is defrosted, the heat exchange with the external air will be maintained, thereby allowing the refrigerant in the liquid guide pipe 1 222 to heat up, thereby removing the frost on the entire liquid guide pipe 1 222 and the heat dissipation fin 2 32;

[0042] Frost will accumulate on the cleaning fin member 1 218 and the cleaning fin member 220, and slowly fall into the lower liquid outlet box 410 at the bottom under the action of gravity. As the heat dissipates, it turns into liquid and accumulates inside the lower liquid outlet box 410. The rotation of the upper gear member 2111 will drive the vertical long transmission rod 41, which in turn drives the upper vertical rod 43 and the vertical reciprocating wire rod member 44 to rotate through the transmission belt assembly 42, so that the outer moving plate member 46 and the scraper member 47 can reciprocate up and down, and the scraper member 47 can reciprocate up and down. The contact between the outer movable plate 46 and the scraper member 47 and the dustproof mesh plate 18 removes the dust accumulated on the dustproof mesh plate 18 to achieve the purpose of dust removal. When the outer movable plate 46 and the scraper member 47 move to the bottom, they will press the sealing member 49 downward, and the spring between the sealing member 49 and the lower liquid outlet box 410 will accumulate force and stretch, and the sealing member 49 will slide in the slide groove of the lower liquid outlet box 410. The water accumulated in the lower liquid outlet box 410 will be discharged and flow on the scraper member 47, so as to clean the dust scraped off the scraper member 47.

[0043] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
