  • the present invention relates to the field of air conditioner, more particularly, to a ventilation method for an air conditioner.
  • air is ventilated in a fixed angle and direction because they are already determined when designing the air conditioner, moreover, the way of ventilating air in need of cooling is identical to the way in need of heating, without taking into consideration of factors such as actual room size, room structure, actual ventilation effects when the air conditioner is installed at different positions of the room, and characteristics of cold air and hot air.
  • the practical usage of air conditioner is affected by the above mentioned factors, as a result, the efficiency of the air conditioner is decreased, and it is difficult to meet personal requirements on comfort, more important, it causes waste of resources.
  • the present invention overcomes deficiencies of prior art technology by providing a personalized ventilation method for an air conditioner, by which the air blowing angle can be adjusted in accordance with external environment.
  • air blowing durations to the left and to the right are adjusted at the same time when the air blowing angles to the left and to the right are adjusted; wherein said air blowing durations to the left and to the right comprises air blowing duration to the left and air blowing duration to the right, which are respectively in direct proportion to the air blowing angle to the left and to the air blowing angle to the right.
  • ⁇ upper & lower arctg ⁇ b L - arctg ⁇ b - H Y - p ; wherein "Y” denotes the distance between the wall on which the air conditioner is located and the opposite wall, “p” denotes the depth of the air conditioner, “b” denotes the distance from the center of the air conditioner to the ground, “H” denotes the distance from the ground to the highest point on the opposite wall at which the air flow from the air conditioner can reach, “L” denotes the distance between the projection of the air conditioner on the ground and the nearest point at which the air flow from the air conditioner can reach on the ground.
  • the initial parameters required such as room dimension, dimension of the air conditioner itself, relative dimension of the installation position of the air conditioner
  • the air conditioner's intelligent sensing or manual measurements wherein the intelligent sensing is realized by installing an intelligent sensing device in the air conditioner so as to automatically scan the initial parameters of the room dimension and relative dimension of the installation position of the air conditioner; the manual measurement is realized by on-site measuring so as to determine the initial parameters.
  • Air blowing angle and air blowing duration are controlled by an air ventilation motor
  • the air ventilation motor can be controlled in way of continuous accurate controlling.
  • said way of continuous accurate controlling comprises the following steps: after obtaining the initial parameters by means of intelligent sensing or manual measurement, data is input in a controller chip of an air ventilation control system, particular data of air blowing angles for the installation position of the air conditioner is calculated by the calculation formula which is preset in the system, each group of different initial data corresponding to a group of data of air blowing angles, thereby the way of continuous accurate controlling is achieved.
  • Air blowing angle and air blowing duration are controlled by an air ventilation motor, the air ventilation motor can be controlled in way of dial-code controlling; wherein said way of dial-code controlling comprises the following steps: considering different capacities of air conditioners corresponding to different dimensions of rooms, based on the typical relative installation position of the air conditioner, several groups of initial parameters are predetermined and set into a plurality of fixed control modes, then a proper control mode is chosen therefrom in accordance with room dimension and the actual installation position of the air conditioner.
  • the way of dial-code controlling comprises a direct dial-code controlling and a remote dial-code controlling.
  • air flows can be more evenly distributed with the present invention, room can be cooled down at the same cooling level with 15% time off and warmed up with 20% time off. Thereby room temperature is able to reach at what user desires quickly and stably in a more comfortable way, besides the air conditioner works more efficiently and lots of resources are saved.
  • a personalized ventilation method for an air conditioner is realized by adjusting air blowing angles and air blowing durations to the left and to the right according to the installation position of the air conditioner, the room dimension and the shape of the air conditioner itself.
  • the air blowing angles comprise air blowing angle to the upper, air blowing angle to the lower, air blowing angle to the left, and air blowing angle to the right.
  • Y denotes the distance between the wall on which the air conditioner is located and the opposite wall
  • p denotes the depth of the air conditioner
  • b denotes the distance from the center of the air conditioner to the ground
  • H denotes the distance from the ground to the highest point on the opposite wall at which the air flow from the air conditioner can reach
