Definitions

  • the invention belongs to the technical field of air conditioning, and relates only to a split wall-mounted air conditioner which uses a cross-flow fan for heat exchange.
  • Split wall-mounted air conditioners include indoor units and outdoor units.
  • the indoor unit is mainly composed of a heat exchanger and a cross flow fan.
  • the cross-flow fan mainly comprises a cross-flow impeller and a volute, and the volute of the wind-flow part of the cross-flow fan constitutes a wind duct, and the volute forming the wind duct is an outlet duct wall.
  • the indoor air is sucked into the indoor unit under the action of the cross-flow impeller, and is heat-exchanged by heat exchange with the heat exchanger, and then passes through the cross-flow impeller, and is blown out by the indoor air outlet duct.
  • the air outlet ducts of the existing split-wall air-conditioning indoor unit cross-flow impellers are all closed air passages having a rectangular cross section, and the heat exchange air is isolated from the indoor air outside the air outlet duct before being blown out. Therefore, all of the air outlet ducts are blown by the heat exchange air.
  • the temperature difference between the inlet and outlet of the split-wall air-conditioning indoor unit is about 14 degrees. The heat exchange of such a large temperature difference produces a large temperature difference with respect to the original indoor air temperature.
  • the air conditioner is intermittently turned on and off around the set temperature to regulate the working condition of the room temperature. The air temperature of the indoor unit is lower.
  • the human body If the human body is subjected to the direct blow of the indoor unit, it will be felt. It’s very cold, and it’s often called “air conditioning sickness” when it’s blown out by the indoor unit with too much temperature difference. This problem is caused by people who are sick and sick, children, when people sleep. Especially outstanding.
  • it is necessary to provide a mixed air supply device to improve the temperature difference between the indoor unit air and the indoor air.
  • the characteristics of the cross-flow fan in the indoor unit determine that the wind duct should be designed to be as narrow as possible.
  • the cost reduction and aesthetics of the indoor unit also require a miniaturized design. Therefore, the air duct of the cross-flow fan cannot be designed.
  • the normal air supply device is accommodated.
  • the air supply device is forcibly set, and the air outlet air passage is blocked, which seriously affects the wind pressure and the air output.
  • an air supply device cannot be provided in an indoor air duct having a cross-flow fan for heat exchange.
  • the Chinese patent No. CN203857578U the first page of the patent specification entitled “An Air Conditioner” clearly states that “the existing air conditioners with installation parts generally use cross-flow fans, cross-flow fans, air ducts and air outlets. The positional relationship determines that it is difficult to provide an additional air supply device therein.”
  • the cross flow fan here is a cross flow impeller.
  • the technicians in the field of air conditioning always put the design of the air supply device on the outside of the air outlet of the indoor unit, and set up a wide variety of air guiding and air blowing devices, such as upper and lower air guiding, left and right air guiding,

  • the technical solution of the D patent has three shortcomings: 1.
  • the space formed by the outside of the air duct wall of the air-conditioning indoor unit and the indoor unit casing is the only air-conditioning connecting pipe and air-conditioning drain pipe that can be used to set the insulation pipe package.
  • the tubes and lines almost occupy the space outside the wall of the wind duct and close to the outside of the wind duct wall of the cross-flow fan, and the existing air-conditioned indoor unit comes from aesthetics and cost saving. In other words, they tend to be ultra-thin and miniaturized. After ultra-thin and miniaturized design, this space is even narrower. It has become very difficult to set these pipes and wires in this narrow space. Therefore, the cross-flow fan is out of the wind. There is no extra space on the outside of the road wall to accommodate the air intake component.
  • the additional air inlet is far away from the air outlet to avoid the problem that the air outlet of the indoor air outlet is recirculated through the additional air inlet.
  • the thickness of the machine that is, the dimension perpendicular to the wall, has been generally 300MM thick from the early years, and the thin design has been designed to the current 135MM-200MM.
  • the additional air inlet is designed on the indoor casing to be farther away from the air outlet. It is impossible to exceed the thickness of the indoor unit.
  • One inlet and one air inlet are only 135MM-200MM apart, especially the inlet and outlet air inlet and outlet angles are less than 90°, and the backflow problem cannot be avoided.
  • This recirculation area of the wall-mounted air conditioner is located at the lower edge of the indoor unit, usually away from the active area of the person in the room, and the backflow causes the air volume of the indoor unit to be blown to the indoor activity area of the indoor person who usually needs air conditioning to be reduced, and the amount of air output is reduced for the target area. Therefore, the D patent can not only reduce the time and energy consumption required for the indoor air to reach the set temperature, but also it is difficult to achieve the technical effect of the second invention of the D patent. 3.
