Problems solved by technology

[0004] However, the above two control methods do not consider the influence of fresh air on the indoor temperature. Therefore, when the indoor temperature has reached the requirement, the indoor air is still supplied or the indoor temperature is not met. The compressor of the air conditioner is in the running state for a long time or frequently starts and stops, which will affect the reliability of the compressor operation of the fresh air air conditioner, and lead to problems such as shortened service life, high power consumption and poor comfort

Embodiment 1

[0098] Figure 4 It shows a curve change diagram of outdoor energy demand and outdoor air supply temperature according to an embodiment of the present invention.

[0099] Such as Figure 4 As shown, when the air conditioner is running in the cooling mode, the outdoor energy demand changes with the outdoor air supply temperature curve as shown in Figure 4 As shown, when the outdoor air supply temperature satisfies 04 S +t 1 , the outdoor energy demand is always 0%, which is reflected from the image as a straight line ab with a slope of zero.

[0100] When the outdoor supply air temperature meets T S +t 1 ≤ T 4 ≤ T S +t 2 , the outdoor energy demand increases linearly from 0% to 100% according to the first preset slope, which is reflected in the image as a straight line bc with a positive slope.

[0101] When the outdoor supply air temperature meets T 4 >T S +t 2 , the outdoor energy demand is always 100%, which is reflected from the image as a straight line with a s...

Embodiment 2

[0103] Figure 5 It shows the graph of indoor energy demand changing with indoor temperature according to an embodiment of the present invention.

[0104] When the air conditioner is running in cooling mode, the indoor energy demand changes with the indoor temperature curve as follows: Figure 5 As shown, when the indoor temperature satisfies T 1 >T S +t 3 , the indoor energy demand is always 100%, which is reflected from the image as a straight line with a slope of zero (such as Figure 5 h to +∞ shown).

[0105] When the indoor temperature satisfies T S ≤ T 1 ≤ T S +t 3 , the indoor energy needs increase linearly from 0% to 100% according to the second preset slope, which is reflected in the image as a straight line fh with a positive slope.

[0106] When the indoor temperature satisfies T S -t 4 1 S , the indoor energy demand is always 0%, which is reflected in the image as a straight line ef with a slope of zero.

[0107] When the indoor temperature satisfies T...

Embodiment 3

[0110] Figure 6 It shows a curve change graph of outdoor energy demand versus outdoor air supply temperature according to another embodiment of the present invention.

[0111] When the air conditioner is running in heating mode, the outdoor energy demand varies with the outdoor supply air temperature curve as follows: Figure 6 As shown, when the outdoor air supply temperature satisfies 0>T 4 >T S -t 6 , the outdoor energy demand is always 0%, which is reflected in the image as a straight line jk with a slope of zero.

[0112] When the outdoor supply air temperature meets T S -t 7 ≤ T 4 ≤ T S -t 6 , the outdoor energy demand decreases linearly from 100% to 0% according to the fourth preset slope, which is reflected in the image as a straight line ij with a negative slope.

[0113] When the outdoor supply air temperature meets T 4 S -t 7 , the outdoor energy demand is always 100%, which is reflected from the image as a straight line with a slope of zero (such as F...

Abstract

The invention provides a running control method, a running control device and an air conditioner. The running control method comprises the steps that the outdoor supply air temperature and the indoortemperature are detected in real time by responding to the set temperature inputted by a user; the corresponding total energy requirement is determined according to the first temperature difference between the indoor temperature and the set temperature and the second temperature difference between the outdoor supply air temperature and the set temperature; and the running mode of a compressor is adjusted according to the total energy requirement. By means of the running control method, the influence of the outdoor supply air temperature on the indoor temperature is taken into full consideration, the relationship between the indoor temperature and the outdoor supply air temperature is established according to the total energy requirement, then the running mode of the compressor is adjustedaccording to the total energy requirement, and therefore the influence of the outdoor supply air temperature on the indoor temperature is reduced, the indoor temperature control requirement is met, the running power consumption of the air conditioner is reduced, the running reliability of the air conditioner can be conveniently improved, the service life of the air conditioner is prolonged, and the user experience is improved.

Description

technical field [0001] The present invention relates to an air conditioner control method, in particular to an operation control method, an operation control device and an air conditioner. Background technique [0002] The fresh air air conditioner is an air conditioner with a fresh air system. When the air conditioner is cooling or heating, the fresh air system of the air conditioner can introduce air from the outside to improve the indoor air quality. [0003] In related technologies, there are generally two control methods for fresh air conditioners: (1) controlling the operation or shutdown of the compressor of the fresh air conditioner through the temperature difference between the indoor temperature and the set temperature; The temperature difference fresh air at a certain temperature controls the operation or shutdown of the compressor of the air conditioner. [0004] However, the above two control methods do not consider the influence of fresh air on the indoor temp...
