Tab. 2.e
Notice :
1. Maximum compressor current draw value increased by 2 A to take into
account current for the controller and optional kits;
2. When calculating the maximum current draw, it is assumed that the
defrost heaters and compressor operate simultaneously. Therefore, this
value includes all the auxiliary loads, at the maximum allowed value,
plus the compressor. The following example shows how to calculate
the maximum current draw of the HB200C0300CE0 unit (with single-
phase power supply), i.e. 39.8 A. This value is the sum of: Maximum
compressor current (6.4 A), maximum control board current (25.4 A),
maximum anti-sweat heater kit current (8 A);
3. Nominal conditions for medium temperature operation; Evaporating
temperature -10°C, superheat 10 K, subcooling 0 K, condensing
temperature 20°C, compressor rotation speed 80 rps;
4. Nominal conditions for low temperature operation; Evaporating
temperature -30°C, superheat 10 K, subcooling 0 K, condensing
temperature 20°C, compressor rotation speed 80 rps;
5. The data refer to a flow-rate of water containing 20% of antifreeze
additive (ethylene glycol) by volume. For different percentages of
antifreeze additive, the performance and pressure drop data may
differ from those shown in the table;
6. Automatic pressure switch reset at 61 barg;
7. Limit temperature with box charged with refrigerant and not
operating. Exceeding the maximum temperature can cause the safety
valve to open and consequent downtime for maintenance (refrigerant
charge and replacement of the safety valve).
