Cooling module, HPC CMThe operational description for the cooling module is available in the controller manual .

Installation

ApplicationThe cooling module controls the temperature of a cooling using a pilot valve . The cold is collected from a cooling tank, which is cooled with active or passive cold .

Passive cold means that cooling agent fluid is circulated through the drill hole and the cooling tank, without activation ofanyheatingpump.Onlycirculationpumpsforcoolingagentsareused.Theheatfromthecoolingtankistransporteddown into the mountain . An assumption for passive cooling to work is that the cooling agent fluid is colder than the coo-ling tank .

Active cooling means that a heat pump is activated to lower the temperature of the cooling agent, before it is transferred into the cooling tank . If the cooling integral continues to rise, more heat pumps are started . The valve for active cooling changes its mode and disconnects the drill hole . Therefore, the cooling agent only circulates through the cooling tank and heat pump, so that all the produced cold can be collected .

Additionally, a dew point control function can be activated in the cooling module . This function is not necessary, but if it is used a dew point sensor must be connected .

Surplus heat produced during active cooling can either be returned to the drill hole or cooled in a coolant cooler . If a coolant cooler is used, a temperature sensor is connected for the cooler and the coolant module then controls the cooling fans .
