THE COOLING CAPACITY DOES NOT CONSIDER THE SUPPLY FAN MOTOR THERMAL LOAD
1. U = Under, downflow / O = Over, upflow
2. Characteristics referred to entering air at 26°C-40%RH with chilled water temperature 7-12°C - 0% glycol
3. SHR = Sensible cooling capacity / Total cooling capacity.
T_tNEXTDFDX_0719_EN
DUAL FLUID system on the machine allows to obtain two independent cooling systems:
•
Chilled water coil
•
Direct expansion coil
Air conditioner
The microprocessor control system automatically manages the system, by activating the cooling circuit
more convenient according to the parameters set.
With this system, it is possible, with a limited use of space, to solve several plant problems such as:
•
Chilled water coil fed with chilled water or mains water as a stand-by of the main cooling
circuit.
•
Double chilled water feeding with two independent circuit. This solution is used when you
need to ensure redundancy of the cooling system.
The temperature control is performed with the same logic of the main coil.
