Problems solved by technology

[0007] The third type is the anti-cold wind control in the whole process, but the temperature value of the anti-cold wind is fixed, and the indoor speed is limited to a few speeds after the anti-cold wind, and the speed of the anti-cold wind varies greatly
Therefore, when switching from one anti-cold wind speed control to another anti-cold wind speed control, due to the large change in speed, the temperature TC of the indoor heat exchanger will have a large increase with the large decrease in speed, which may be due to the increase in TC temperature Go back to the original speed control, repeat this way, the speed of the indoor fan fluctuates from high to low

Embodiment

[0028] The principle diagram of the present invention is as figure 1 As shown, in the present invention, the anti-cold wind temperature value is related to the set temperature, and the anti-cold wind temperature is no longer a fixed parameter value, but a function of the set temperature, that is, the anti-cold wind temperature TE is a function of the set temperature TS, TE=B+f(TS), B is a constant, and its value is different according to different models; and in the process of entering the anti-cold wind, the speed of the indoor fan is related to the temperature TC of the indoor heat exchanger, that is, the temperature of the indoor heat exchanger TC During the ascent, W1=(TC-TE2)÷(TE1-TE2)×(WS-W0)+W0=(TC-B2-f(TS))÷(B1-B2)×(WS-W0)+W0 , during the descent, W2=(TC-TE5)÷(TE4-TE5)×(WS-W0)+W0=(TC-B5-f(TS))÷(B4-B5)×(WS-W0)+ W0.

[0029] In this embodiment, the control method of the present invention includes the following steps: preset the anti-cold wind values ​​of six groups of ...

Abstract

The invention discloses a method for controlling the temperature of outlet air of an air conditioner. The air conditioner is provided with different cold-air preventive temperatures TE for preventing cold air from being blown out from an air outlet, each cold-air preventive temperature TE and set temperature TS meets functional relation of TE=B+f(TS), when the set temperature TS rises, the cold-air preventive temperatures TE rise, when the set temperature TS drops, the cold-air preventive temperatures TE drop, simultaneously, an indoor fan can run at set rotation speed WS, gentle-breeze rotation speed W0, shutdown speed and rotation speed between the WS and the W0 according to different cold-air preventive temperatures TE during heating running of the air conditioner, and the rotation speed W which changes linearly is determined according to the temperature of an indoor heat exchanger. The method for controlling the temperature of outlet air of the air conditioner has the advantages that cold air can be effectively prevented, comfortableness of users is enhanced, and purposes of quick heating and comfortable heating are achieved.

Description

technical field [0001] The invention relates to a method for controlling the outlet air temperature of an air conditioner, which belongs to the transformation technology of the method for controlling the outlet air temperature of the air conditioner. Background technique [0002] When the cooling and heating air conditioner is in heating operation, when the indoor air volume is constant, the outlet air temperature of the air conditioner increases with the increase of the indoor heat exchanger temperature TC, and decreases with the decrease of the indoor heat exchanger temperature TC; at the same time, the air conditioner output The wind temperature decreases with the increase of air volume and increases with the decrease of air volume. When the air conditioner is in heating operation, if there is no anti-cold wind control, when the temperature of the indoor heat exchanger TC is low, for example, it is lower than the indoor set temperature TS, there will be low-temperature wi...
