If the air conditioner is not working, check the electricity connection to both system components air conditioner system within the building and the external heat-exchanger or condenser. Whilst it is normal practice to not put air conditioners on the output of uninterruptible power supplies (to prevent over sizing of the UPS system and its batteries), air conditioners may be classed as essential loads and supported by a standby power generator. Mains Power Supply and Power OutagesĪir conditioners and cooling or chiller systems are powered from AC electricity sources and normally the mains power supply to the building. If your air conditioner is not under maintenance, we always recommend an assessment. A maintenance contract will normally include preventative maintenance visits during which consumables like filters are either cleaned or replaced. Air conditioners also have air filters which can become blocked over time. Alternative, air flow could be disrupted by the moving of racks or removal of blanking plates from a server rack. Air vents can become blocked through the placing of equipment or packing in the wrong place most commonly during works inside the white space area. When designing cooling systems for server rooms or datacentres it is best practice to model the environment and install some form of hot-isle, cold-isle containment and air flow planning. Airflow Restrictions, Obstructions and Inefficiencies For thermostats and air conditioners connected to an IP network, there is also the potential for a breach in cybersecurity. A quick visual and manual check can suffice here. More likely the thermostat temperature setting has been altered either manually or remotely via the BMS or DCIM suite. Typical cooling system faults include: AC Thermostat Setting or Thermostat FailureĪ complete failure is unlikely but can occur. The call-out may be under warranty or outside warranty (chargeable) or covered by an on-site air conditioning system maintenance contract. Simple faults may be cleared on-site but often it will be necessary to call-out an HVAC (heating ventilation and air conditioner) engineer. Once a fault is indicated, it is then important to identify the actual fault, cause, impact and rectification process. The air conditioner may also show a red warning light on its front panel. Should a fault condition arise the cooling system will generate an alarm and this can be transmitted along a suitable cable connection (signal contact or network IP address) to a management console interface. Air Conditioner FaultsĪir conditioning systems installed within more critical applications tend to be monitored remotely via a building management system ( BMS) or data centre infrastructure management ( DCIM) suite. value regulated lead acid batteries) which can age more quickly in environments above 25☌. Some devices such as uninterruptible power supplies may also have temperature sensitive assemblies (e.g. Whilst most IT and electronic systems will work up to 40☌ this can have a limiting effect on operational life leading to earlier than planned for failures and potential service interruption. This is important to protect temperature-sensitive systems within the environment and also to provide comfortable working conditioners for the people who have to entire the ‘white space’ area. In terms of server rooms and datacentres operators need to ensure that the environment they operate their IT systems within is within an ambient temperature of 20-25☌. When an air conditioner fails to operate at the required thermostatically controlled temperature the implications can range from general discomfort to service interruption and even a critical system failure. Most air conditioners provide two ambient environment related functions: cooling and heating. For many people, air conditioning could be considered a utility-type service without which they simply cannot function. This growth is also fueled not just by climate change but the growing tendency for IT based operations (server rooms and datacentres) and the general growth of industry and commercialisation across our planet. It is not getting any cooler and the demand for air conditioning systems continues to grow worldwide.
