The invention discloses a control method for a combined refrigerating multi-split air conditioner
system. The multi-split air conditioner
system is characterized in that two or more outdoor combined refrigerating modules are arranged the outdoor side to form a cold
source system of the multi-split air conditioner
system, each outdoor combined refrigerating module is composed of a first
refrigerant vapor compression and
refrigeration circulating loop and a second
refrigerant circulating loop, one or more direct
evaporation type
indoor air cooler modules are arranged at the indoor side, and a
refrigerant storing and conveying unit is connected with the part between each outdoor combined refrigerating module and the corresponding
indoor air cooler module to form a closed circulating system through a liquid collecting tube, a main liquid supply tube and a main air return tube. According to the control method for the combined refrigerating multi-split air conditioner system, the number of the indoor and outdoor modules is decided according to the designed
thermal load of an air conditioner, and the control method precisely regulates the refrigerating capacity to meet the
heat control needs of round-the-
clock running data
machine rooms and
electronic equipment; the control method for the combined refrigerating multi-split air conditioner system is capable of making the maximum use of the natural cold source of the day and night,
transition season and winter so as to realize the great
energy conservation and emission reduction of the air conditioner system.
