Problems solved by technology

[0002] Existing household air conditioners, if the indoor fan is not running, or if a certain air conditioner does not have an indoor fan, there is no set of reliable control logic to ensure that the temperature of the heat exchanger is always within the appropriate operating range. Air conditioners and indoor units are prone to frosting, and the indoor and outdoor heat exchangers have high temperatures, which are easy to burn users and bring poor user experience

Embodiment 1

[0080] Embodiment 1: The compressor of the radiant air conditioner runs at a constant frequency for a preset time;

Embodiment 2

[0081] Embodiment 2: When the operating parameters of the radiant air conditioner are inconvenient, the temperature of any test point of the radiant air conditioner does not change within the first preset time. Here, the temperature of any test point of the radiant air conditioner can be determined according to the actual situation. Specific setting of factors such as the working environment of the radiant air conditioner and the model of the radiant air conditioner;

Embodiment 3

[0082] Embodiment 3: On the premise that the voltage of the radiant air conditioner is stable, the fluctuation range of the current of the radiant air conditioner within the first preset time is within the first preset fluctuation range.

[0083] Of course, it can be understood that there may be other methods for judging the stable operation of the radiant air conditioner, which are not limited here.

[0084] In some embodiments of the present invention, before the air conditioner enters the radiation mode, fault detection is also performed on the air conditioner to determine whether there is a component failure. The main control mechanism and protection control mechanism of the air conditioner are revised. Wherein, the component failure here may refer to the temperature sensing package failure in the air conditioner. Of course, it is understandable that the component failure may also be the failure of other structures or components, which is not limited here.

Abstract

The invention discloses a radiation air conditioner and a heat exchanger protection control method and device. The heat exchanger protection control method comprises the following steps that firstly,when the radiation air conditioner enters a radiation mode and is in a stable operation state, the operation state of the radiation air conditioner is judged; if the radiation air conditioner runs ina refrigeration manner, the outlet temperature of an indoor heat exchanger of the radiation air conditioner or the inlet temperature of an outdoor heat exchanger of the radiation air conditioner is obtained, the operation frequency of a compressor of the radiation air conditioner is controlled according to the outlet temperature of the indoor heat exchanger or the inlet temperature of the outdoorheat exchanger; and if the radiation air conditioner runs in a heating manner, the outlet temperature of the indoor heat exchanger of the radiation air conditioner is obtained, and the operation frequency of the compressor of the radiation air conditioner is controlled according to the outlet temperature of the indoor heat exchanger. According to the heat exchanger protection control method for the radiation air conditioner, the indoor heat exchanger and the outdoor heat exchanger can be well protected, and the user experience is good.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a protection control method and device for a radiant air conditioner and a heat exchanger. Background technique [0002] Existing household air conditioners, if the indoor fan is not running, or if a certain air conditioner does not have an indoor fan, there is no set of reliable control logic to ensure that the temperature of the heat exchanger is always within the appropriate operating range. Air conditioners and indoor units are prone to frosting, and the temperature of the indoor and outdoor heat exchangers is high, which is easy to burn the user and bring a poor experience to the user. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art. Therefore, the first purpose of the present invention is to provide a heat exchanger protection control method for a radiant air conditioner, whi...
