Embodiment 1

[0031] figure 1 is a flowchart of a control method according to an embodiment of the present invention, such as figure 1 As shown, the method includes the following steps (step S101-step S102):

[0032] Step S101, detecting the operating status of the electrical equipment through an alarm detector.

[0033] In this embodiment, the alarm detector includes at least: a fire detector and / or a refrigerant concentration detector.

[0034] Step S102, when the alarm detector detects an abnormal situation, control the abnormal situation.

[0035] Specifically, if the abnormal condition is fire danger, when the fire detector detects fire danger, the fire extinguishing controller is triggered to release carbon dioxide. If the abnormal condition is refrigerant leakage, when the refrigerant concentration detector detects refrigerant leakage, the compressor is triggered to stop, the internal fan is triggered to run at high wind speed, and the small fan is triggered to run. Further, the v...

Embodiment 2

[0040] corresponds to figure 1 Introducing the control method, this embodiment provides a control device, such as figure 2 Shown is a structural block diagram of the control wash, the device includes:

[0041] The detection module 10 is configured to detect the operation status of electrical equipment through an alarm detector; the above-mentioned alarm detector may include: a fire detector and / or a refrigerant concentration detector.

[0042] The control module 20 is connected to the detection module 10 and is used for controlling the abnormal condition when the alarm detector detects the abnormal condition.

[0043] In this embodiment, the control module 20 may include: a fire control unit, configured to trigger the fire extinguishing controller to release carbon dioxide when the fire detector detects a fire danger. And / or, the refrigerant control unit is configured to, when the refrigerant concentration detector detects refrigerant leakage, trigger the compressor to stop...

Embodiment 3

[0046] This embodiment provides an air conditioner, such as image 3 The structural block diagram of the air conditioner is shown, the device includes: the control device introduced in the second embodiment, and an alarm detector for detecting the operating status of electrical equipment.

[0047] The air conditioner in this embodiment also includes: a fire extinguishing controller, used for releasing carbon dioxide under the control of the control device when the alarm detector detects a fire; and / or, a small fan, used for when the alarm detector detects a fire , start running under the control of the control device. Based on this, fast and accurate control can be carried out when abnormal conditions are found, so as to eliminate potential safety hazards.

[0048] The air conditioner in this embodiment further includes: an alarm device, configured to give an alarm when the alarm detector detects an abnormal condition; and stop alarming when the alarm detector detects that th...

Abstract

The invention discloses a control method and device and an air conditioner. The method comprises the steps of conducting detection on the operation condition of electrical equipment through an alarm detector; and when the abnormal condition is detected through the alarm detector, controlling the abnormal condition. According to the control method and device and the air conditioner, a refrigerant concentration detector, a fire detector, a small fan and a fire extinguishing device containing carbon dioxide are arranged on an indoor unit, so that the electrical equipment adopting combustible type refrigerant is protected; fire danger is avoided to the greatest extent; the mass of the refrigerant of the indoor unit is reduced; the requisite condition for combustion explosion after the refrigerant leaks is eliminated; and safety of users is guaranteed to the utmost extent.

Description

technical field [0001] The technical field of electrical appliances of the present invention, in particular, relates to a control method, device and air conditioner. Background technique [0002] In the current electrical equipment, the main refrigerants used are R22 and R410A, but in the context of global warming and the destruction of the ozone layer, R22 and R410A are not ideal refrigerants because of the ODP (ozone depression potential) of R22 and GWP (Global Warming Potential, Global Warming Potential) are high, belonging to the eliminated refrigerant. The ODP value of R410A is low, but its GWP value is higher than that of R22, which is a transitional replacement refrigerant. [0003] At present, there is a more environmentally friendly refrigerant R290 (propane), the ODP value is basically 0, and it does not damage the ozone layer at all. With a GWP value of 20, compared to other refrigerants, it has minimal impact on global warming. In order to prevent global warmi...
