Problems solved by technology

[0002] Most of the air conditioners in the related art use the operation of the indoor fan to blow the cold air or hot air after the heat exchange of the indoor unit into the room to cool or heat the room. At the same time, it affects the user's sense of experience, and the radiant air conditioner in the related art, because the indoor fan does not run, or does not have an indoor fan, therefore, the compressor is prone to the risk of liquid shock during operation

Embodiment 1

[0068] Embodiment 1: The compressor of the radiant air conditioner runs at a constant frequency for a first preset time;

Embodiment 2

[0069] Embodiment 2: When the operating parameters of the radiant air conditioner are inconvenient, the temperature of a certain point of the radiant air conditioner does not change within the first preset time. Here, the temperature of a certain point of the radiant air conditioner can be determined according to the actual The working environment and the model of the radiant air conditioner are set in detail;

Embodiment 3

[0070] 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.

[0071] 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.

[0072] In some embodiments of the present invention, the temperature parameter of the compressor includes the return air temperature of the compressor, wherein the operating frequency of the compressor is controlled according to the relationship between the evaporating temperature of the radiant air conditioner and the temperature parameter of the compressor, including : If the evaporation temperature of the radiant air conditioner is greater than the sum of the return air temperature of the compressor and the preset temperature threshold, the operating frequency of the control c...

Abstract

The invention discloses a radiation air conditioner and a compressor protection control method and device. The compressor protection control method comprises the following steps that firstly, when theradiation air conditioner enters a radiation mode and is in a stable operation state, the evaporation temperature of the radiation air conditioner and the temperature parameter of a compressor are obtained; then the relation between the evaporation temperature of the radiation air conditioner and the temperature parameter of the compressor is judged; and finally, the operation frequency of the compressor is controlled according to the relation between the evaporation temperature of the radiation air conditioner and the temperature parameter of the compressor to prevent liquid impact of the compressor. According to the compressor protection control method of the radiation air conditioner, the operation state of the radiation air conditioner in the refrigeration mode or the heating mode canbe well adapted, and the damage to the compressor and the radiation air conditioner due to the liquid impact of the compressor can further be prevented.

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 compressor. Background technique [0002] Most of the air conditioners in the related art use the operation of the indoor fan to blow the cold air or hot air after the heat exchange of the indoor unit into the room to cool or heat the room. At the same time, it affects the user's sense of experience, and the radiant air conditioner in the related art is prone to the risk of liquid shock when the compressor is running because the indoor fan is not running or does not have an indoor fan. 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 object of the present invention is to provide a protection control method for a compressor of a radiant air conditioner, which can avoid liquid hammering of...
