Problems solved by technology

[0002] During the heating process of the air conditioner, due to the limitation of the installation height and the design of the air outlet, there is a large temperature difference between the air outlet temperature of the air conditioner in the heating mode and the indoor ambient temperature, and the hot air sent from the air outlet of the air conditioner The wind speed attenuates quickly, so it is difficult for the hot wind to fall to the ground, resulting in serious stratification of the indoor temperature field

Embodiment Construction

[0044] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0045] The applicant has found through theoretical calculation and research that: when the fan rotates at the same speed, the lower the indoor temperature, the higher the outlet air temperature, the smaller the relative density, the greater the air volume, and the higher the outlet air speed. but from figure 1 From the attenuation curve of the air supply speed versus the air supply temperature difference shown, it can be seen that as long as there is a supply air temperature difference in the heating mode, the air supply speed will attenuate. exist figure 1 Among them, when the temperature difference of the air outlet is greater than T9, the air outlet speed attenuates quickly, and it has basically attenuated to 0 before reaching the ground. For example, the attenuation of the ground...

Abstract

The invention discloses a method and a device for controlling heating of an air conditioner. The method comprises the following steps: step one, starting an electric auxiliary heating device and a compressor after entering a heating mode, controlling an air deflector to be at a first air guiding angle and running an inner fan at a first rotating speed; step two, after reaching the first preset time of the heating mode, acquiring a first temperature difference for expressing blowing temperature difference and a second temperature difference for expressing the difference between the tube temperature of an internal engine heat exchanger and the indoor environment temperature; step three, comparing the magnitude relationship between the first temperature difference and the second temperature difference; and step four, controlling the frequency of the compressor and / or the starting / stopping of the electric auxiliary heating device and / or the air guiding angle of the air defector and / or the rotating speed of the fan according to the magnitude relationship. According to the method provided by the invention, the purposes of hot wind landing and quick rise of indoor temperature can be achieved and the maximization of the heating effect of the air conditioner can be realized.

Description

technical field [0001] The present invention relates to the field of air conditioning, in particular to an air conditioning heating control method and device. Background technique [0002] During the heating process of the air conditioner, due to the limitation of the installation height and the design of the air outlet, there is a large temperature difference between the air outlet temperature of the air conditioner in the heating mode and the indoor ambient temperature, and the hot air sent from the air outlet of the air conditioner The wind speed attenuates quickly, so it is difficult for hot wind to fall to the ground, resulting in serious stratification of the indoor temperature field. Contents of the invention [0003] Embodiments of the present invention provide an air-conditioning heating control method and device capable of causing hot air to fall to the ground and rapidly increasing the indoor temperature. [0004] In order to achieve the above purpose, an embod...
