Embodiment Construction

[0061] In order to make the above objects, features and advantages of the present invention more comprehensible, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0062] Such as figure 1 As shown, it is the flow chart of the control method for the high temperature protection of the air conditioner Figure 1 ; Wherein, the control method of the high temperature protection of the air conditioner includes:

[0063] Step 100, obtaining the temperature of the inner panel of the air conditioner;

[0064] Step 200, judging whether the temperature of the inner disk is greater than a second temperature threshold;

[0065] When the air conditioner starts heating operation, the temperature of the inner panel of the air conditioner and the operating pressure of the entire system will rise synchronously. If the temperature of the inner panel of the air conditioner and the operating pressure of the entire syste...

Abstract

The invention provides an air conditioner high-temperature protection control method and an air conditioner high-temperature protection control device. The control method comprises the following steps: acquiring the inner disk temperature of the air conditioner; judging whether the inner disk temperature is more than a second temperature threshold value or not; if the inner disk temperature is more than the second temperature threshold value, stopping an outer fan of the air conditioner; acquiring the change data of the inner disk temperature of the air conditioner and judging whether the inner disk temperature has rising trend or not according to the change data; and if the inner disk temperature has rising trend, up-regulating the initial wind gear of an indoor fan of the air conditioner. In this way, the inner disk temperature can be reduced timely by adjusting the wind gear of the indoor fan and the problem that the temperature is too high caused by the fact that the inner disk temperature is not reduced timely is solved, so that the inner disk temperature of the air conditioner and the operation pressure of the system are controlled to be within the reasonable range, the air conditioner can operate normally and the use effect and the comfort level of users are improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a control method for high temperature protection of an air conditioner. Background technique [0002] In order to prevent the operating pressure of the air conditioner in heating mode from being too high, the air conditioner generally has the following high temperature protection logic: when the temperature of the inner panel is higher than a certain temperature, the external fan is controlled to stop, and the temperature of the inner panel will start to drop after the outer fan stops; When the temperature of the inner panel is lowered to a certain temperature, the external fan is restarted to start heating; this cycle controls the temperature of the inner panel of the air conditioner within a reasonable range. [0003] However, this protection logic is only applicable to conventional air conditioners. For some existing models of air conditioners, after the external fan ...
