Chilled Water Precision Air Conditioner utilizes the outdoor cooling source to transfer indoor heat to outdoor heat
exchanger.
When the indoor temperature is higher than set temperature of Chilled Water Precision Air Conditioner, the control
system will send a signal to the Chilled Water Precision Air Conditioner, glycol unit and water pump, to make the
air-cooling unit stop, let the glycol unit and water pump start, also the outdoor free cooling heat exchanger is
energized. The outdoor temperature sensor feeds back the temperature signal of the outdoor free cooling heat exchanger
to the outdoor fan. If the temperature of the outdoor free cooling heat exchanger is higher than the set temperature,
the fan will start unit, the temperature is lower than the set temperature.
When the indoor temperature is lower than set temperature of Chilled Water Precision Air Conditioner, the control system
will send a signal to stop the pump and cut off the power of outdoor fan. So as to ensure indoor constant temperature.
Under the condition of constant temperature, constant humidity and cleanliness of the data center, the unit achieves the
purpose of energy saving and consumption reduction.
