This article describes the appearance, cause, & problems that may occur at cold pour joints in concrete foundation walls and occasionally floors or ceilings. A contraction joint is formed, sawed, or tooled groove in a concrete structure to create a weakened plane to regulate the location of cracking resulting from the dimensional change of different parts of the structure. An isolation joint is a separation between adjacent sections of a concrete. These joints are points where two separate pours of concrete meet, typically due to construction delays, changes in weather, or timing issues during pouring. Here's everything you should know about slab cold joints: What Are Slab Cold Joints? Slab cold joints occur when freshly poured concrete. But do you know what concrete cold joints are? A cold joint in concrete is an area or surface with a structural discontinuity caused by the delayed concrete pouring between two layers of concrete. These joints play a crucial role in maintaining the structural integrity and durability of the. [PDF]

Low-temperature resistant cold aisle for power system computer rooms in Finland

Low-temperature resistant cold aisle for power system computer rooms in Finland

Two solutions use containment of the cold aisle, while the third is based on hot aisle containment. Intake air (cold) and waste air (hot) are unable to mix. It is possible to operate at a higher temperature level through-out the entire system. Cold aisle containment creates an enclosed corridor in front of server cabinets, ensuring that the coldest air goes directly into equipment intakes. By isolating the cold aisle, containment reduces unintended mixing of cold supply air with hot exhaust air, maintaining uniform, predictable. An aisle containment system is a simple way to improve cooling efficiency in hot aisle/cold aisle rack configurations. Essentially creating a room within the aisle, the system helps keep hot and cold air separated to make existing air conditioning systems in data center and edge-of-network. Traditional open aisle data centers use perimeter PAC (precision air conditioning) or CRAC (computer room air conditioning) units to channel cold air up through a raised floor void via grilles positioned in front of the IT cabinets. This has significant disadvantages as there is no separation. Aisle containment is a critical airflow management strategy that separates cold supply air from hot exhaust air within a data center. An enormous amount of energy is used every day to maintain an acceptable intake. [PDF]
