Resfriamento líquido direto no chip: o futuro do gerenciamento térmico de data centers de alta densidade
Data center power densities have surged to 12-30 kW per rack, making liquid cooling essential. Learn how single-phase and two-phase direct-to-chip systems work, refrigerant selection criteria, and critical design considerations for hoses, tubing, and couplings in modern high-density data centers.
Equilíbrio do fluxo de ar do duto
Balancing air systems (ductwork) may be accomplished in various ways. The most common method to accomplish ductwork balancing is Proportional Method. Each diffuser is adjusted to supply the right percentage of total air volume in the ductwork.
Características da Válvula
Why do we need to be aware of the valve characteristics? Every component in a hydronic system has some level of influence on the control and performance of a hydronic system. Valves are key because they are the controlling devices at the critical areas of heat transfer.
Principais sistemas e equipamentos HVAC
A comprehensive list of all the major HVAC system types and related equipment
Baixar manuais de refrigeração Copeland
This is a five series of publications comprising the Emerson Climate Technologies, Inc. Refrigeration Manual. Although each separate part covers a specific area of refrigeration theory and practice, each successive publication presumes a basic understanding of the material presented in the previous sections.
Sistemas de armazenamento de gelo
Thermal energy storage (TES) involves adding heat (thermal) energy to a storage medium, and then removing it from that medium for use at some other time. This may involve storing thermal energy at high temperatures (heat storage) or at low temperatures (cool storage).
Refrigerant Piping Requirements
This guide focuses on systems that use Refrigerant-22 (R-22). While the general requirements are the same for systems that use other refrigerants, velocities and pressure drops will differ.
Life Cycle Cost Analysis Method
The life-cycle cost analysis method is the most commonly accepted method to assess the economic benefits of energy conservation projects over their lifetime. Typically, the method is used to evaluate at least two alternatives of a given project (for instance, evaluate two alternatives for the installation of a new HVAC system: a VAV system or a heat pump system to condition the building). Only one alternative will be selected for implementation based on the economic analysis.
