Abstract
A building sprinkler system includes a pump having an input for receiving water and an output that is connected to selectively feed a plurality of sprinkler heads. A driver is operatively connected to the pump for driving the pump. A cooling arrangement is provided for cooling the pump during pump testing operations. The cooling arrangement includes: a heat exchanger with a primary loop formed by a flow path for delivering water from the output of the pump through the heat exchanger and back to the input of the pump, and a secondary loop formed by a flow path for delivering coolant from the heat exchanger through a radiator and back to the heat exchanger so that heat is transferred from the water to the coolant via the heat exchanger and from the coolant to air via the radiator.
