Floor air conditioner and high temperature refrigeration control method and device of floor air conditioner

Abstract

The invention discloses a floor air conditioner and a high temperature refrigeration control method and device of the floor air conditioner. The high temperature refrigeration control method comprises the following steps that outdoor environmental temperature is obtained, whether the outdoor environmental temperature is equal to or greater than first preset temperature or not is judged, if the outdoor environmental temperature is equal to or greater than first preset temperature, the directions of wind guiding strips is adjusted by controlling a driving motor, so that outlet wind of an indoor machine is blown to a wind returning frame. In this way, load of a compressor can be reduced, it is ensured that the compressor safely and reliably runs, meanwhile, the fluctuation range of indoor temperature can be reduced, and the comfort degree of users is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a high-temperature refrigeration control method for a vertical air conditioner, a high-temperature refrigeration control device for a vertical air conditioner, and a vertical air conditioner with the high-temperature refrigeration control device. Background technique [0002] Usually, the air-conditioning system adopts unloading method to reduce the system load during high-temperature cooling, so as to ensure the safe and reliable operation of the system. For example, by detecting parameters such as the outdoor ambient temperature to determine whether the air conditioning system is in an overloaded state, if so, protect the compressor and the entire air conditioning system from damage by shutting down the compressor, but in high temperature load state, usually more The cooling of the air conditioning system is required to maintain the indoor temperature, so although this...

Problems solved by technology

For example, by detecting parameters such as the outdoor ambient temperature to determine whether the air conditioning system is in an overloaded state, if so, protect the compressor and the entire air conditioning system from damage by shutting down the compressor, but in high temperature load state, usually more The cooling of the air conditioning system is needed to maintain the indoor temperature, so although this method can protect the air conditioning system, it will also cause the indoor temperature to rise, which greatly reduces the user's comfort.

Moreover, in some harsh environments, when the unloading method fails, it will also cause the compressor to shut down due to excessive load.

[0003] In addition, for the fixed-speed air-conditioning system, when the outdoor ambient temperature is high, the protection shutdown can only be carried out based on the judgment of whether the operating range of the unit is exceeded, and the high-temperature operating range of the air-conditioning system cannot be expanded.
