Problems solved by technology

[0002] Problems such as large air-conditioning power consumption and high electricity consumption are still major technical problems faced by all air-conditioning manufacturers, but it is impossible to fundamentally solve these problems by relying solely on air-conditioning designers to optimize the air-conditioning system without good usage habits of users Yes, when the air conditioner is running, if there is a large amount of heat exchange between the indoor environment and the outdoor environment, it will greatly affect the effect of the air conditioner on adjusting the temperature, and it will also increase the power consumption of the air conditioner.
[0003] Chinese patent CN105987477A discloses an air conditioner control method, control device and air conditioner. By detecting the indoor temperature and indoor air pressure when the air conditioner is running, if the indoor temperature does not reach the same level as the air conditioner within the first set time According to the specified temperature corresponding to the current operating state, determine whether the indoor air pressure is the window air pressure, and if so, issue a reminder to close the window; this scheme can determine whether the current environment is a closed environment to a certain extent, but it is limited if it is to be actually operated Too many, for example: 1. It first judges whether the indoor temperature reaches the set temperature within a certain period of time. It does not indicate how to get it within a certain period of time. If the time is too long, the user experience is not good, and if the time is too short, it will cause misjudgment; 2. 1. It uses the air pressure difference to judge whether it is airtight, and the air pressure will not change too much in an environment that is not completely airtight, and the position of the detection air pressure is also likely to affect it, which is difficult to implement; therefore, the present invention proposes a method for detecting airtightness. Space control method, device and air conditioner to solve the deficiencies in the prior art

Embodiment 1

[0024] according to figure 1 As shown, this embodiment proposes a control method for detecting confined spaces, which is applied to air-conditioning units and includes the following steps:

[0025] Calculate the maximum time required for the air conditioning unit to run normally to each windshield and reach the set temperature threshold under different areas, different outer ring temperatures, and different inner ring temperature ranges;

[0026] The operation of calculating the maximum time is carried out during the development stage of the air conditioner. The developer calculates the maximum time for the developed air conditioner. Maximum time required to reach the set temperature threshold:

[0027] Table 1

[0028]

[0029] Note: Table 1 only lists the maximum time value under some parameters. Under different parameters, the maximum time value needs to be calculated specifically.

[0030] The maximum time required for normal operation to each windshield and reaching...

Embodiment 2

[0039] A control method for detecting a confined space, comprising the following steps:

[0040] While calculating the maximum time, it also includes synchronous detection of the tube temperature data of the air conditioner unit in normal operation and without fluorine deficiency, denoted as T 标准管温 .

[0041] By detecting and recording the pipe temperature data of the air-conditioning unit under normal operation and without fluorine deficiency, when the air-conditioning unit is in an abnormal state, the pipe temperature data can be used to judge whether the air-conditioning unit is abnormal due to lack of fluorine at this time. When the real-time detection Tube temperature data and T 标准管温 The difference between the values ​​does not exceed the preset value, indicating that the air-conditioning unit is not short of fluorine, and it is determined that the abnormal state of the air-conditioning is caused by the large amount of heat exchange between the indoor environment and the...

Embodiment 3

[0043] A control method for detecting a confined space, comprising the following steps:

[0044] The set temperature includes the first set temperature T in cooling mode 设定1 , also includes the second set temperature T in cooling mode 设定2 , when the current inner ring temperature in cooling mode > T 设定1 , enter timing operation; when the current inner ring temperature in heating mode 设定2 , enter timing operation;

[0045] In the present invention, when determining the first set temperature T 设定1 and the second set temperature T设定2 value, also includes the first set temperature T 设定1 and the second set temperature T 设定2 Perform compensating operations:

[0046] When performing compensation operation, the first set temperature T 设定1 =T 1 +T 补偿1 , where T 1 is the temperature value input by the user according to the remote control, T 补偿1 ≥1, the temperature value T input by the user according to the remote control 1 =16°C, T 补偿1 =2°C, then the actual first set tempera...

Abstract

The invention discloses a control method and device for detecting a confined space and an air conditioner, relates to the technical field of confined space detection control, and is applied to an air conditioning unit. The method comprises the steps of calculating to obtain the maximum time, and judging the difference value between the current inner ring temperature and the set temperature when the air conditioning unit operates normally; judging whether timing operation is started or not according to the difference value, determining the difference value between the timing variable and the calculated maximum time, determining whether the air conditioning unit is in an abnormal state or not according to the difference value, and when the air conditioning unit is in the abnormal state, sending reminding information; and if the air conditioner is in the abnormal state, showing that a large amount of heat exchange exists between the current indoor environment and the outdoor environment, and by reminding a user of the situation, preventing the poor user experience caused by human factors so that the user can clearly know the current operation state of the air conditioner unit, energy waste can be avoided on the basis of enhancing the user experience. The energy consumption problem in the operation process of the air conditioner can be controlled.
