Getting Your HVAC Units Ready For The Winter Months in Silicon Valley

The central heating, ventilation, and air-conditioning (HVAC) system that serves your facility is important to your operations in the summer months, but it can take on even more significance in the winter if your facility includes data-center infrastructure. This is because, during colder weather, both your indoor heating and cooling systems must work in concert to keep your equipment at the proper operating temperatures.

If you take proactive steps to prepare your main and server-room cooling equipment for impending cold weather, you can prevent weather-related damage, repair existing issues, and optimize the performance of your climate-control systems. Some critical elements of the main-facility HVAC winterization process include:

  • Energy Audits: This process involves an overall check of the energy-efficiency of your facility. By weighing your existing energy usage against established baselines, our auditors can detect inefficiencies and suggest ways of improving energy-usage.
  • Infrastructure Inspections: Your HVAC system likely includes a network of pipes, coils, ducts, fittings, and more. These vital components require regular maintenance checks, and especially so before major seasonal weather changes. Some common service items include refrigerant tests, pressure and leaks tests, and thermostat calibrations.
  • Temperature Zone Consistency Check: If your facility is large, it likely includes several temperature and environmental zones within its structure. Keeping the temperatures in each zone at the proper levels requires regular maintenance of related environmental control hardware and software.

Server-Room Cooling Systems

The soundness of your server-side cooling systems is just as essential to the health of your enterprise. These systems keep your servers and their surrounding environment within temperature and humidity ranges set by the American Society of Heating Refrigeration and Air Conditioning Engineers (ASHRAE) data-center guidelines. Common cooling system designs include:

  • Liquid Cooled Systems: These cooling designs use liquid-antifreeze to capture and remove server-generated heat. Checks of these components may involve antifreeze fluid level and chemical composition tests. In addition, structural integrity checks are often performed on piping.
  • Air-Cooled Systems: Air-cooled designs use chilled air to cool hot server racks and rooms. Maintenance checks for these types of systems often include duct, inlet, and outlet inspections. Technicians often use this opportunity to sample and adjust humidity levels.

Keeping your data-center cooling apparatus in good operating condition is key to the success of your enterprise.
