Cold Storage Air Cooler: Cold Bridge Cut-off Design and Heat Leak Control on Mounting Structure

Cold bridge forms when metal components directly connect cold inner space and warm building structure, bringing continuous heat infiltration into cold storage. Metal suspension brackets passing through insulation layers become the main cold bridge path, increasing warehouse heat load steadily all year round. Xindacool cold room evaporator adopts non-metal isolation gaskets installed between bracket and cold room panel to break the metal heat conduction path. Without cold bridge isolation, surface condensation and icing will appear on exposed metal parts outside the cold room panel, accelerating insulation aging. The isolation gasket must withstand long-term low temperature and pressure deformation. Ordinary rubber will creep and lose sealing performance after several years. The penetration hole around suspension bolts should be fully filled with foam insulation. Air gaps left in openings create extra heat and moisture entry channels. For multi-layer suspended air coolers, each hanging point needs independent isolation treatment. Partial omitted gaskets still form effective cold bridge. When calculating total heat load of cold storage, heat loss from cold bridge must be counted, otherwise cooling capacity selection will be insufficient. Check external side of mounting penetration points during annual inspection. If frost or wet stains are visible, the cold bridge isolation has failed. Copper refrigerant pipes passing through wall panels also need isolation sleeves. Direct contact between copper tube and metal frame creates another cold bridge. High humidity ambient conditions amplify cold bridge side effects. Moisture condenses along metal path and gradually damages surrounding polyurethane insulation.

FAQ

Q: What is cold bridge in cold storage installation? A: Metal parts directly linking cold interior and warm outside conduct heat continuously and increase heat load. Q: How to cut off cold bridge for air cooler suspension bracket? A: Install non-metal isolation gaskets between bracket and cold room insulation panel. Q: What sign indicates cold bridge isolation failure? A: Frost or wet marks appear on the outer surface of panel penetration positions. Q: Why fill bolt holes with foam insulation? A: Eliminate air gaps to block heat and moisture infiltration around suspension penetration openings. Q: What risk if no cold bridge isolation gasket? A: Continuous heat transfer, outer surface icing and accelerated aging of cold room insulation material. Q: Can copper refrigerant pipe through panel form cold bridge? A: Yes, copper tube contacting metal frame needs isolation sleeve to stop heat conduction. Q: What property required for cold bridge isolation gasket? A: Stable under sustained low temperature, resistant to compression creep and long service life. Q: Shall cold bridge heat loss be counted in cooling load calculation? A: Yes, otherwise the selected air cooler may lack enough cooling capacity.
