Temporary Cooling During HVAC Upgrades

Like any other mechanically oriented system and equipment…commercial HVAC systems eventually need to be replaced. Smart facilities managers that follow best maintenance practices can slow down deterioration and maximize useful life…replacement is inevitable.

Consequently, major operations disruptions are unavoidable and need to be planned for by maintenance and engineering managers since substantial areas of the facility could go without air conditioning for time periods ranging from days to months.  The potential impact on building occupants is obvious.  Temporarily relocating operations to other areas is one alternative, but most won’t have that flexibility.

Fortunately, the marketplace has provided multiple options for temporary cooling solutions.  They range from small, self-contained units for cooling a moderate sized room, often called “spot cooling”…to massive trailer-mounted units capable of cooling entire buildings.

In either scenario, advanced planing by managers is required to achieve an effective temporary cooling plan. They must:

  1. Size the units to meet the cooling load…
  2. Understand power requirements for the temporary unit and make power available, and…
  3. Lock in purchase or rental contracts well in advance of time needed for deployment.

Waiting for a crisis to occur that will ultimately require the use of a portable unit, can only lead to project delays or disruption of services.

Advanced Needs Assessment dictates that Managers must start the planning process by identifying areas served by the system being upgraded.  Next, they will have to determine the amount of cooling capacity these areas need.  Managers need to size temporary units so they have adequate capacity to properly cool and dehumidify the area the units served.
