Problems solved by technology

However, when the air conditioner is just starting to cool, the indoor ambient temperature is relatively high. At this time, if the air conditioner is operated at the maximum circulating air volume, the actual air temperature of the air conditioner will be too high, and the wind will blow to the user, making the user feel that the air conditioner has poor cooling comfort.
For example: air conditioner refrigeration, when the user just turns on the air conditioner, the indoor temperature is 33 degrees Celsius, at this time, the indoor unit of the air conditioner operates at a circulating air volume of 660 cubic meters per hour, and the outlet air temperature is 27 degrees Celsius, and the user faces the air outlet in front of the air conditioner , do not feel cool, therefore, poor physical comfort
[0003] Similarly, when the air conditioner starts heating, the indoor ambient temperature is low. At this time, the air conditioner is still running at the maximum circulating air volume, resulting in the actual air supply temperature of the air conditioner being low, and the wind blows to the user, causing the user to feel the air conditioner heating Poor effect, poor heating comfort
For example: air conditioner heating, when the user just turns on the air conditioner, the indoor temperature is 5 degrees Celsius. The air vents do not feel warm, so the body-feeling heating comfort is poor
[0004] In addition, after the air conditioning system has been used for a long time, the actual cooling and heating capacity of the air conditioner is reduced due to refrigerant leakage or the outdoor unit is dirty. The actual air temperature of the air conditioner is too high during cooling, or the temperature of the air blown out during heating is relatively low, which makes the user feel poor comfort

Embodiment Construction

[0034]It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] Such as figure 1 and figure 2 As shown, the preferred embodiment of the present invention proposes an air conditioner: including a controller 1, an indoor air temperature sensor 2, an air conditioner outlet temperature sensor 3, an indoor unit evaporator 4, an indoor unit fan 5, a remote controller 6 and an outdoor air conditioner Compressor system 7 etc., among which:

[0036] The indoor air temperature sensor 2 can be located at the air inlet of the air conditioner indoor unit evaporator 4 (such as figure 1 shown) or located in the remote control 6 (such as figure 2 shown), the remote controller 6 communicates wirelessly with the controller 1 through infrared rays.

[0037] The indoor air temperature sensor 2 is used to detect the indoor temperature Tn, which is the indoor temperature at the air inlet of...

Abstract

The invention discloses an air-conditioner and an outlet air temperature controlling method thereof. The air-conditioner comprises an indoor unit fan, an indoor air temperature sensor, an outlet air temperature sensor, a controller and the like; and when the indoor temperature Tn does not reach the temperature Ts set by a user, the controller adjusts the revolving speed N of the indoor unit fan of the air-conditioner by using a proportion integration differentiation (PID) algorithm according to the current refrigerating or heating mode of the air-conditioner, so that the outlet air temperature Tc of the air-conditioner is not higher than the refrigerating outlet air comfortable temperature value T1 of the air-conditioner or not lower than the heating outlet air comfortable temperature value T2 of the air-conditioner. According to the air-conditioner, the revolving speed of the indoor unit fan of the air-conditioner is dynamically adjusted through the PID algorithm according to the actual outlet air temperature at the air outlet of an indoor unit of the air-conditioner and the indoor environmental temperature, and then the magnitude of the circulating air quantity of the indoor unit of the air-conditioner is adjusted, so that the actual outlet air temperature of the indoor unit of the air-conditioner runs at a specific comfortable and relatively constant temperature during refrigerating and heating, and the refrigerating and heating comfort of the air-conditioner is improved; and the air-conditioner has the advantages of energy conservation, environment friendliness, economical efficiency and practicability.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner and a method for controlling the outlet air temperature thereof. Background technique [0002] At present, when the conventional air conditioner system is cooling and heating, the indoor unit of the air conditioner is directly operated at the maximum wind speed. However, when the air conditioner is just starting to cool, the indoor ambient temperature is relatively high. At this time, if the air conditioner is operated at the maximum circulating air volume, the actual air temperature of the air conditioner will be too high, and the wind will blow to the user, making the user feel that the air conditioner has poor cooling comfort. . For example: air conditioner refrigeration, when the user just turns on the air conditioner, the indoor temperature is 33 degrees Celsius, at this time, the indoor unit of the air conditioner operates at a circulating air v...
