Abstract
An auxiliary cooling ramp system and method are provided. The system includes an auxiliary ramp operatively connectable, using a plurality of flexible hoses, to water lines of a water circuit of a cooling system, between a cooling unit and a heat exchange system of the cooling system. The method includes installing the auxiliary ramp to water lines of a water circuit of a cooling system, between a cooling unit and a heat exchange system of the cooling system; performing maintenance on the cooling system via the auxiliary ramp; and disconnecting the auxiliary ramp.
Claims20
An auxiliary ramp system comprising:
- an auxiliary ramp unit comprising:
- a supply manifold,
- a return manifold,
- a pressure-independent balancing valve operatively connected between the supply manifold and the return manifold,
- a safety valve operatively connected to the return manifold, and
- a drain/filling valve operatively connected to one of the supply manifold and the return manifold;
- and
- a plurality of flexible hoses comprising:
- a supply input hose configured to attach to an input of the supply manifold,
- a supply output hose configured to attach to an output of the supply manifold,
- a return input hose configured to attach to an input of the return manifold, and
- a return output hose configured to attach to an output of the return manifold.
A cooling system maintenance method comprising:
- draining water from a water circuit of a combined cooling system comprising a cooling unit and a heat exchange system;
- filling the water circuit with first water via an auxiliary ramp unit, allowing the first water to circulate in the water circuit, and draining the first water from the water circuit,
- wherein the auxiliary ramp unit is operatively connected on lines of the water circuit between the cooling unit and the heat exchange system;
- filling the water circuit with a first mixture comprising water and a dispersant via the auxiliary ramp unit, allowing the first mixture to circulate in the water circuit, and draining the first mixture from the water circuit;
- filling the water circuit with second water via the auxiliary ramp unit, allowing the second water to circulate in the water circuit, and draining the second water from the water circuit;
- filling the water circuit with a second mixture comprising water and a passivizer/degreaser, allowing the second mixture to circulate in the water circuit, and draining the second mixture;
- filling the water circuit with third water via the auxiliary ramp unit, allowing the third water to circulate in the water circuit, and draining the second water from the water circuit;
- and
- filling the water circuit with a softened water mixture via the auxiliary ramp unit.
