The invention discloses an
automatic control method based on a water-cooled air conditioner internal unit. The
automatic control method comprises the steps as follows: (1) initializing a
control system; (2) setting initial values of an automatic loading
system, wherein the initial values include an initial temperature value, an initial internal unit fan speed value and an initial
solenoid valve opening value; (3) collecting the air outlet temperature in real time and detecting the internal unit fan speed and the
solenoid valve opening degree; (4) judging if the air outlet temperature is equal to the initial temperature value, if so, going to the step (5), if not, adjusting the internal unit fan speed and the
solenoid valve opening degree for an internal unit freezing
water gap according to difference values, determining adjustment ranges, and adjusting until the air outlet temperature is equal to the initial temperature value; and (5) adjusting according to the step (4), drawing a curve chart and displaying through a
display device. According to the
automatic control method, the
energy consumption for conditioning an equipment environment under the same
heat load change in a water-cooled air conditioner unit is reduced, the proportion of
energy consumption of air conditioner equipment in
total energy consumption of a
machine room is reduced, the PUE (
Power Usage Efficiency) value of the
machine room is reduced, and the energy-saving effect is improved.
