Problems solved by technology

If the pressure difference between the condenser and the evaporator is not large enough, the cooling refrigerant cannot be smoothly input into the compressor, and the electrical components in the compressor cannot be cooled sufficiently, which will cause the compressor to fail to operate stably continuously, resulting in The entire air conditioning unit does not run stably or even properly

Abstract

The invention discloses a direct-expansion type air conditioning unit and a control method thereof. The method comprises the steps of when a compressor of the air conditioning unit operates, acquiring the outdoor environment temperature, and comparing with a known outer environment temperature threshold value; if the outdoor environment temperature is not smaller than the outer environment temperature threshold value, adjusting the rotating speed of a condenser fan in the air conditioning unit according to the exhaust pressure of the air conditioning unit; and if the outdoor environment temperature is smaller than the outer environment temperature threshold value, adjusting the rotating speed of the condenser fan according to the internal temperature of the compressor. By applying the direct-expansion type air conditioning unit and the control method thereof provided by the invention, the stable operation of the air conditioning unit can be improved.

Description

technical field [0001] The invention belongs to the technical field of air treatment, in particular relates to an air conditioner unit, more specifically relates to a direct expansion air conditioner unit and a control method thereof. Background technique [0002] The direct expansion air conditioner unit has its own compressor. The liquid refrigerant in the refrigeration system directly exchanges heat with the air to be treated outside the coil in the evaporator coil, absorbing the heat of the air outside the coil and directly evaporating, realizing the cooling of the coil outside the coil. cooling of the air. Since the refrigerant directly completes the heat exchange with the air to be processed, without secondary heat exchange in the middle to absorb heat and cool the air outside the coil, the heat exchange efficiency is high and the temperature adjustment range is wide, so it is widely used in various industries. [0003] For direct expansion air conditioner units, the ...
