The invention discloses a control method and device of a multi-connected unit system and the system with the control device. The method includes the steps that when the multi-connected unit system isstarted in a hot manner, the target indoor unit energy requirement is determined according to indoor temperatures corresponding to to-be-strated target indoor units in multiple indoor units and the indoor unit set temperature; the total energy requirement of the multi-connected unit system is determined according to the outdoor temperature and the target indoor unit energy requirement; the outdoorunit initial operation target value corresponding to different ratios is obtained according to the ratio between the total energy requirement of the multi-connected unit system and the total capacityof outdoor units; and compressors are started, and the operation frequency of the compressors is regulated according to the initial operation target value of the outdoor units and temperature of heatexchangers in the target indoor units. By means of the method, when the multi-connected unit system is started in the hot manner, the operation frequency of the compressors is regulated according tothe initial operation target value of the outdoor units and the temperature of the heat exchangers in the target indoor units, the time during which the system reaches the set temperature is prolonged, it is avoided that the system is frequently started and stopped, reliability and economical efficiency of the system are improved, the energy consumption is lowered, and more energy is saved.
Description
technical field [0001] The invention relates to the technical field of household appliances, in particular to a control method and device for a multi-connected system and a system having the same. Background technique [0002] related technologies, such as figure 1 As shown, the multi-line system consists of a compressor 1, a four-way valve 2, a condenser 3, an electronic expansion valve (including an electronic expansion valve 401, an electronic expansion valve 402, and an electronic expansion valve 403), a high-pressure pressure sensor 5, and a low-pressure pressure sensor 6 , low-pressure liquid storage tank 7, evaporator (comprising evaporator 801 and evaporator 802), outdoor blower fan, several large parts of outdoor heat exchanger to form. Among them, the compressors used in the multi-line system are mainly divided into two types: scroll compressors and rotary compressors. [0003] However, in related technologies, the multi-connected system generally operates accord...
