Heating ventilation and air conditioning 391 conditioners to operate on 440 V 3-phase 60 Hz supply. Power consumption 1.2 kw per unit. At least 7 litres s of fresh air per occupant of room should be taken from machinery space system. The shipbuilder should pipe condenser cooling water from ship s services. Erosion of condenser piping may be prevented by fitting a Constaflo control valve in each unit to limit flow to 0.15 litre s per unit. This proposal is exclusive of heating. The shipbuilder should supply and fit suitable bases for units provide switches wire up to motors and switches and supply and fit cooling water drain piping and fittings. Installation serving the cargo pump room The cargo pump room is ventilated by two axial flow exhaust fans each to extract 1.4m3 s against 3.1 mbar static requiring a total of 2.25 kw. The fans should be of split case bevel .
