[0002] The control scheme of fixed-speed air-conditioning system using double-cylinder variable-capacity compressors in the existing market is similar to that of conventional fixed-speed machines, and cannot fully utilize the cooling and heating advantages of dual-cylinder variable-capacity compressors; and lacks interaction with users. The main purpose of the invention is to design a control scheme. In the normal mode, single-cylinder operation is adopted, and the state of single-cylinder operation is equivalent to a conventional fixed-speed air conditioner; on this basis, a super-powerful mode is added, which can switch between large and small Cylinder, can maximize the efficiency of the use of the advantages of the double-cylinder compressor to achieve the effect of rapid cooling and heating, strong dehumidification; this mode is added on the remote control for customers to choose, which can increase the interaction with users, so that customers can operate according to their own needs the air conditioner

[0108] refer to Figure 5 , Figure 5 It is a schematic flowchart of the fifth embodiment of the air conditioning system control method of the present invention. Based on the first embodiment of the above method, it also includes:

[0109] Step S17, in the dual-cylinder operation, if the compressor current is higher than the preset current first threshold value, enter the current protection and switch to single-cylinder operation; when the compressor current is lower than the compressor current fixed threshold value, exit the current protection Protect;

[0110] In super mode operation, when the air conditioner is in double-cylinder operation, the current measuring device is used to measure the compressor current. The current measuring device is built into the air conditioner as an accessory, or is measured by electronic measuring equipment associated with the air conditioner. If the measured compressor current is higher than the preset current first threshold value (Iproh)...

Abstract

The invention discloses a method for controlling an air conditioning system. The method comprises the steps that a superstrong mode start control signal is received; an air conditioner is switched to operate in a superstrong mode; the current indoor temperature T1 is measured, and the temperature difference value between the current indoor temperature T1 and the set temperature Ts is calculated; if the temperature difference value is smaller than or equal to a preset threshold value, single-cylinder operation is adopted; and if the temperature difference value is larger than the preset threshold value, dual-cylinder operation is adopted. The invention further discloses a device for controlling the air conditioning system. According to the method and device for controlling the air conditioning system, the effects of quick refrigerating and heating and strong dehumidification are achieved by utilizing the advantages of a dual-cylinder compressor at the maximum efficiency.
