Problems solved by technology

[0003] The purpose of the present invention is to provide a method for controlling the temperature of the air outlet of an air conditioner, which aims to solve the problem of the temperature at the air outlet of the existing air conditioner due to the temperature attenuation between the indoor heat exchanger and the air outlet and the continuous operation frequency of the compressor. Unable to keep constant at the user-set temperature value, and the problem of increased power consumption when the compressor operating frequency continues to exceed the operating frequency required to achieve the preset temperature value

example 1

[0097] When the air conditioner is in cooling mode, the ambient temperature is 30°C, the preset cooling output frequency range of the air conditioner is [10Hz, 120Hz], and the preset heating output frequency range is [10Hz, 160Hz], then the maximum cooling output frequency is 120Hz, the minimum cooling output frequency is 10Hz, the maximum heating output frequency is 160Hz, the minimum heating output frequency is 10Hz, the preset air outlet temperature value T set by the user 2s 24°C, cooling temperature decay compensation value B 1 The temperature is 3°C, and the preset start time is 5 minutes. After the air conditioner starts and runs at the maximum cooling output frequency of 120Hz for 5 minutes, it starts to obtain the temperature value T of the indoor heat exchanger 2 and learned to be T 2 =18°C, according to the formula (1) to get the refrigeration temperature difference deviation value X 1 =18-(24-3)=-5°C, then further according to the preset frequency change compari...

[0099] When the air conditioner is in heating mode, the ambient temperature is 15°C, the preset cooling output frequency range of the air conditioner is [10Hz, 120Hz], and the preset heating output frequency range is [10Hz, 160Hz], then the maximum cooling output frequency 120Hz, the minimum cooling output frequency is 10Hz, the maximum heating output frequency is 160Hz, and the minimum heating output frequency is 10Hz. The preset air outlet temperature value T set by the user 2s at 26°C, heating temperature decay compensation value B 2 The temperature is 6°C, and the preset start time is 5 minutes. After the air conditioner starts and runs at the maximum heating output frequency of 160Hz for 5 minutes, it starts to obtain the temperature value T of the indoor heat exchanger 2 and learned to be T 2 =26°C, according to formula (2) to get the deviation value of heating temperature difference X 2 =(26+6)-26=6℃, then further according to the preset frequency change comparison ...

Abstract

The invention belongs to the technical field of air conditioner control and provides an air conditioner running control method and device. The air conditioner running control method includes detecting temperature of an indoor heat exchanger and acquiring a temperature value of the indoor heat exchanger; acquiring refrigerating or heating temperature difference deviation value according to the temperature value of the indoor heat exchanger, a preset air outlet temperature value and a refrigerating or heating temperature attenuation compensation value; acquiring a refrigerating or heating frequency changing rate from refrigerating or heating temperature difference changing tendency according to the refrigerating or heating temperature difference deviation value; acquiring refrigerating or heating correction output frequency according to current compressor running frequency and the refrigerating or heating frequency changing rate; according to a relationship between the refrigerating or heating correction output frequency and a preset output frequency interval, controlling a compressor to run according to the refrigerating or heating correction output frequency or maximum refrigerating or heating output frequency, thereby enabling air outlet temperature to be constantly maintained at a preset air outlet temperature value set by a user by adjusting running frequency of the compressor. By the air conditioner running control method and device, power consumption can be reduced correspondingly to achieve the objectives of energy conservation and emission reduction.

Description

technical field [0001] The invention belongs to the technical field of air conditioner control, and in particular relates to an air conditioner operation control method and device. Background technique [0002] The air conditioner needs to consume a lot of energy in the process of lowering or raising the indoor temperature to the preset temperature through the cooling or heating mode. However, when the existing air conditioner is cooling or heating, it operates according to the preset temperature. If the frequency of the air is sent to the outside to achieve cooling or heating, there will be temperature attenuation when the air reaches the air outlet from the indoor heat exchanger. For example, when the indoor temperature is high and cooling is required, because the air will Therefore, the temperature of the air reaching the air outlet is higher than the temperature of the indoor heat exchanger; when the indoor temperature is low and heating is required, because the air will...
