Problems solved by technology

Although this solution is cheap, because there are different operating stages in the operation of air-conditioning products, the same standard often triggers frequency reduction by mistake, which in turn leads to poor cooling or heating effects

no. 1 example

[0033] Please refer to figure 1 , a temperature protection control method provided by the embodiment of the present invention aims to ensure that the system pressure of the air conditioner 1 can be effectively reduced, and at the same time avoid the temporary coil high temperature triggering the frequency reduction of the air conditioner 1 when it does not enter the stable operation stage. Then affect the use effect of the air conditioner 1 . Such as figure 1 As shown, the temperature protection control method may include the following steps:

[0034] Step S101, determine whether to enter the stable operation stage.

[0035] In the embodiment of the present invention, it is first judged whether the air conditioner 1 has entered a stable operation stage. Optionally, the manner of determining whether to enter the stable operation stage may be to obtain the running time of the compressor, that is, to count the time from the start of the operation of the compressor to obtain th...

[0081] Please refer to Figure 4 , Figure 4 A schematic diagram of functional modules of an air conditioner 1 is provided for an embodiment of the invention. Such as Figure 4 As shown, the air conditioner 1 includes:

[0082] Judgment module 2, used to judge whether to enter the stable operation stage.

[0083] The first execution module 3 is configured to start the first temperature protection strategy if the stable operation stage is not entered.

[0084] The second execution module 4 is configured to activate a second temperature protection strategy when entering the stable operation stage, wherein the second temperature protection strategy is different from the first temperature protection strategy in triggering conditions for controlling the compressor .

[0085] Preferably, the second execution module 4 is specifically configured to: collect the coil temperature of the heat exchanger at preset time intervals. When the collected temperature of the coil tube is hig...

Abstract

The invention provides a temperature protection control method and an air conditioner. The temperature protection control method comprises the steps that whether the air conditioner is in a stable operation stage or not is judged; if the air conditioner is not in the stable operation stage, the first temperature protection strategy is adopted; if the air conditioner is in the stable operation stage, the second temperature protection strategy is started; since the second temperature protection strategy and the first temperature protection strategy are different in triggering conditions of control over a compressor, and it means that by the adoption of the temperature protection strategies for different operation stages, temperature protection is conducted on the air conditioner. In this way, it can be ensured that temperature protection can effectively lower the system pressure, it is avoided that a poor effect is caused when frequency lowering is triggered under the condition that theair conditioner is not in the stable operation stage, and therefore the reliability and the use effect of the air conditioner are improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning protection, in particular to a temperature protection control method and an air conditioner. Background technique [0002] The installation environment has a great influence on the use of air conditioners. Taking the ambient temperature as an example, if the ambient temperature is too high, it will directly cause the system pressure of the air conditioner to increase. The increase of system pressure will affect the stability of air conditioning products. At the same time, it is difficult to control the installation environment of air-conditioning equipment, especially for outdoor units of air-conditioning equipment that are usually installed in a small outdoor space, and the corresponding ambient temperature is almost difficult to be manually intervened. [0003] In order to solve the excessive system pressure of the air-conditioning product due to the high ambient temperature, the solu...
