The invention discloses an air conditioning system and a control method thereof. The air conditioning system comprises an outdoor unit and multiple indoor units; the outdoor unit is provided with an outdoor unit mainboard for controlling output of the outdoor unit; the indoor units are connected with the outdoor unit separately, each indoor unit is provided with an indoor unit mainboard and a temperature detecting element which is connected with the indoor unit mainboard, the temperature detecting elements are arranged at inlets of the indoor units to detect the inlet temperature of the indoor units, and the indoor unit mainboards are connected with the outdoor unit mainboard and used for transmitting the inlet temperature to the outdoor unit mainboard. According to the embodiment of the air conditioning system, the temperature detecting elements can detect the inlet temperature of the indoor units by being arranged at the inlets of the indoor units and connected with the outdoor unit; due to the fact that the inlet temperature approaches to or is equal to the evaporating temperature, the outdoor unit mainboard can control the output of the outdoor unit by detecting the inlet temperature, and then the evaporating temperature is accurately controlled; the control cost is lower, and the operation energy need of the outdoor unit can be better controlled.
Description
technical field [0001] The present invention relates to the technical field of refrigeration equipment, and more particularly, to an air conditioning system and a control method of the air conditioning system. Background technique [0002] Multi-connection products are usually one or more outdoor units corresponding to multiple indoor units. In the actual operation process, there will be a corresponding relationship between the output of the outdoor unit and the number of indoor units that are turned on. key technology. [0003] There are generally two ways to solve the energy demand control. The first type: the outdoor unit is equipped with a low-pressure pressure sensor, and the outdoor unit obtains the evaporation temperature of the system through the low-pressure pressure value, so as to control the evaporation temperature of the system by adjusting the output of the outdoor unit; the second type: at the outlet of the indoor heat exchanger of the indoor unit Install a ...
