Abstract

The invention provides a control method of an air conditioning system and the air conditioning system. The control method of the air conditioning system includes the following steps that S10, a unit of the air conditioning system is switched into a compressor double-cylinder operating state; S20, the operating frequency of a compressor is controlled to be F; S30, circulation is conducted according to a preset time period, and an indoor environment temperature Tring and a temperature target Tset set by a user are circularly measured; S41, if the difference between the Tring and the Tset is larger than a preset value T, the operating frequency F of the compressor confirms to the formula: A(Tring-Tset)+B+E; S42, if the difference between the Tring and the Tset is smaller than or equal to the preset value T, the operating frequency Fn of the compressor conforms to the formula: Fn-1[D+C(Tn-Tn-1)]/D. The adjusting range of the system refrigerating/heating amount is widened, and energy efficiency and comfort are improved.

Description

technical field [0001] The present invention relates to the field of air conditioning, in particular to a method for controlling an air conditioning system and the air conditioning system. Background technique [0002] Existing air conditioners generally have the following situation: due to differences in indoor and outdoor temperatures or the number of multi-connected indoor units running, the same air conditioning system may be in different operating load conditions under different circumstances. Only when the cooling / heating output of the air conditioner reaches a balance with the heat load of the indoor environment can the indoor temperature be stabilized at the target temperature set by the user. Therefore, adjusting the cooling / heating capacity of the air conditioning system according to the ambient heat load is a necessary condition for stabilizing the indoor temperature. [0003] For the above situation, the general practice of existing air conditioners is: [0004...
