Server Room Portable Air Conditioner — Spot Cooling for IT Rooms, Network Closets, and Edge Data Centers

The required BTU/h equals the total heat load of your IT equipment plus 10–20% for non-IT loads. Convert watts to BTU/h by multiplying by 3.412. For example, a 3 kW heat load equals approximately 10,200 BTU/h. The SHISHUO SSPAC-35 provides approximately 11,900 BTU/h of cooling, which would cover this load with margin. For critical environments, apply a 30% safety margin.

Yes, for small server rooms and network closets with heat loads under 5 kW. The SSPAC-27 through SSPAC-50 covers rooms from approximately 10 to 30 m². For larger rooms or heat loads above 5 kW, a portable AC is better used as supplemental or emergency backup cooling alongside a dedicated CRAC (computer room air conditioner) or precision cooling system.

ASHRAE TC 9.9 recommends maintaining server inlet temperatures between 18°C and 27°C (64–81°F) for Class A1 equipment. Most IT managers target 20–25°C for a balance between equipment reliability and energy efficiency. The allowable range extends up to 32°C, but sustained operation above 27°C may increase fan speed, noise, and component wear.

The most common method in commercial buildings is to route the hot air exhaust duct through a removable ceiling tile into the plenum space above the drop ceiling. This is quick to install, reversible, and does not require wall penetration. Alternatively, the exhaust can be routed through a duct to an adjacent hallway, mechanical room, or exterior wall vent. The key requirement is that the hot exhaust air exits the server room — discharging heat into the same room provides no net cooling.

Yes. SHISHUO SSPAC units include a 24-hour cycle timer and automatic temperature control. For unattended operation, connect an external drain hose for continuous condensate drainage so the unit does not shut down due to a full water tank. Set the target temperature and the timer, and the unit will cycle automatically. For additional safety, pair the unit with a remote temperature monitor that sends alerts if room temperature exceeds a threshold.

A portable AC begins delivering cold air immediately upon startup. The time to bring a room to the target temperature depends on the room's thermal mass, current temperature, and the balance between heat load and cooling capacity. In a typical small server room (15 m²) with a 3–4 kW heat load and an SSPAC-40 (4,000 W cooling), you can expect a noticeable temperature drop within 10–15 minutes and stabilization within 30–60 minutes.

In practice, the terms are used interchangeably in the IT cooling industry. A spot cooler is a portable air conditioner designed for directional, targeted cooling of a specific area rather than uniform room cooling. SHISHUO SSPAC units function as spot coolers — the directional cold air outlet delivers cooling to a specific rack row or hot spot, and the hot exhaust is ducted out of the room.

Yes. We manufacture all units at our Jiaxing production base and support OEM branding and ODM modifications, including voltage adaptation (110V/60Hz for North America, 220V/50Hz standard), custom control interfaces, modified duct configurations, and color or housing changes.
