Air Conditioners

Portable air conditioners deliver spot and space cooling where permanent systems are absent, down, or insufficient. The class runs from small spot coolers to high-tonnage packaged units, with thermostats and control adaptors filed alongside.

Portable Spot Cooler

142 modèles

Fonctionnement

A refrigeration circuit absorbs heat at the evaporator and rejects it at the condenser; the two airstreams must stay separated, which is why portable units duct condenser heat away from the cooled space. Capacity in BTU/h or tons is matched to the space's heat load — occupants, equipment, sun, and air changes.

Types et variantes

Air Conditioners: Portable and spot-cooling units that remove heat from occupied or process spaces.
Thermostats: Controls that regulate temporary heating and cooling equipment.
Communication Adaptors: Interface modules that connect HVAC units to controls and building systems.

Comment choisir

Load calculation drives sizing: roughly 12,000 BTU/h per ton, matched against floor area, heat-producing equipment, and ventilation. Spot coolers aim cold air at people or racks; packaged units condition whole rooms via ducting. Power availability (120 V vs three-phase) and condensate handling are the practical constraints.

Questions fréquentes

How is a temporary air conditioner sized?

By heat load, not floor area alone — equipment wattage, occupancy, glazing, and air changes all add BTUs. Undersized units run continuously without reaching setpoint; grossly oversized ones short-cycle.

Where does the heat go from a portable AC unit?

Out the condenser duct. Every portable unit must reject heat outside the cooled envelope — into a ceiling plenum, adjacent space, or outdoors — or it merely reheats the room.

What do thermostats and adaptors add?

Unattended control. Remote thermostats hold setpoints overnight, and communication adaptors tie temporary units into building controls during renovations.
