Cooling module, HPC CM The operational description for the cooling module is available in the controller manual.
Installation Application The 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 of any heating pump. Only circulation pumps for cooling agents are used. The heat from the cooling tank is transported down into the mountain. An assumption for passive cooling to work is that the cooling agent fluid is colder than the cooling 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.
