Problems solved by technology

[0002] In related technologies, when the air conditioner operates in cooling mode under high-temperature conditions, the high-temperature and high-pressure refrigerant from the compressor enters the outdoor heat exchanger, and after being condensed, it is throttled and enters the indoor heat exchanger for evaporation and cooling. When the outdoor temperature If the cooling space of the outdoor unit is relatively high or the heat dissipation space of the outdoor unit is small, the ventilation and heat dissipation are poor, and the outdoor heat cannot be dissipated in time, which will easily cause the refrigerant pressure in the outdoor heat exchanger to be high, which will easily cause the compressor to trip and stop, affecting customer experience
In order to solve the above problems, the configuration of outdoor units is usually increased, but this will cause a significant increase in the cost of air conditioning

Abstract

Disclosed is a control method of an air conditioning system and an air conditioning system. The control method of the air conditioning system comprises the following steps: the air conditioning systemruns in a refrigeration mode; a temperature T0 of an indoor heat exchanger and a rotation speed n1 of an outdoor fan are measured; and if T0 is greater than or equal to a first preset temperature T1,the rotation speed n1 of the outdoor fan is controlled to increase to n2. According to the control method of the air conditioning system in the embodiment of the present invention, when the air conditioning system runs in the refrigeration mode, the outlet temperature of the indoor heat exchanger is measured to timely and accurately obtain operation conditions of the air conditioning system; andwhen the air conditioning system is under a high-temperature working condition, the rotation speed of the outdoor fan is accelerated to speed up the heat dissipation of the outdoor heat exchanger, sothat the temperature of a refrigerant at an outlet of the outdoor heat exchanger is lowered, the normal operation of the air conditioning system is guaranteed, the high-temperature protection of the air conditioning system is implemented, the frequent tripping of a compressor is prevented, the refrigeration capacity of the air conditioning system under the high-temperature working condition can beguaranteed, the indoor environment comfort is improved, and the user experience is improved.
