💡 FAQ
Quick guide to selection, procurement, and installation essentials for UPS and precision air conditioning systems
Four-step method for UPS power selection:
① Calculate the total load power —— Calculate the sum of the rated power of all equipment that needs protection.
② Determine UPS capacity — It is recommended that the load does not exceed the UPS rated capacity of 70%-80%。
③ Determine backup time —— Standard Computer Room Recommendations 15-30 minutes, and critical business suggestions over 1 hour.
④ Consider future expansion — Reserve capacity for 20%-30%.
Comparison of three major brands:
KehuaDomestic tier-one brand, high cost-performance, suitable for small and medium-sized server rooms.
Vertiv--Formerly Emerson, technologically leading, suitable for large data centers.
SchneiderGlobal brand, modular design, suitable for high-end scenarios.
Four-factor calculation method:
① Equipment heat generation —— Device power consumption 90%-95% convert into heat
② Data Center Area —— About per square meter 150-250W Refrigeration capacity
③ Envelope -- Reserved 10%-15% Allowance.
④ People and Lighting — Approximately per person 100–150 W。
Lithium-ion Battery—High energy density, long cycle life (2,000+ cycles), and compact size, but relatively expensive; suitable for applications with limited space where a long service life is a priority.
Lead-acid battery——Mature technology, low cost, and simple maintenance, but bulky with a short lifespan (3-5 years), suitable for small and medium-sized server rooms with a limited budget and ample space.
Core advantages of modular data centers:
① Rapid deployment —— Shorter Construction Time 50% That's all.
② Elastic scaling Scale on demand to avoid excessive initial investment.
3. Highly efficient and energy-saving —— PUE can be as low as 1.2 Below.
④ Standardized delivery — Controllable quality, reducing on-site construction risks.
three entries and three exitsThis refers to a UPS where both the input and output are three-phase AC (380 V).
Applicable scenarios: High-power UPS (above 10kVA), large data centers, industrial equipment, etc.
Advantages: High power density, high efficiency, and suitable for heavy loads.
High-frequency UPS— Compact, highly efficient (95%+), and cost-effective, making it ideal for small and medium-sized data centers and corporate offices.
industrial frequency UPS——High impact resistance, high reliability, and good isolation, suitable for large data centers, industrial environments, medical and other scenarios.
Room-level—Placed in the corner or on the side of the server room to cool the entire room, suitable for low-density server rooms (single cabinet power ≤ 5kW).
inter-row level—Placed between cabinet rows, providing cooling close to the heat source with high cooling efficiency, suitable for high-density data centers (single cabinet power ≥ 5kW).
Standard installation cycle:
Small and medium UPS (1-10kVA)—— 1-2 days。
Large UPS (10kVA and above)—— 3-5 days。
precision air conditioner—— 2-4 days(including copper pipe welding and refrigerant charging).
modular data center—— 7-15 days。
Yes! We provide nationwide logistics and distribution services.
Delivery method: Dedicated logistics lines, Debon, SF Express, etc., ensure that the equipment arrives safely and on time.
Coverage: All provinces and cities nationwide, including remote areas (Tibet, Xinjiang, Qinghai, etc.).
Regular maintenance is recommended!
Quarterly inspection—Check battery voltage, fan operation, dust cleaning, etc.
Annual maintenance—Battery capacity test, internal dust removal, parameter calibration, etc.
Battery replacement cycle- Lead-acid battery 3-5 yearslithium battery 8-10 years。
Precision air conditioner energy efficiency standards:
acceptance criteria——EER ≥ 3.0(National Grade 3 Energy Efficiency).
良好标准——EER ≥ 3.5（国家二级能效）。
优秀标准——EER ≥ 4.0（国家一级能效，EC风机）。
Formula for calculating battery capacity:
Battery capacity (Ah) = Load power (W) × Backup time (h) ÷ Battery voltage (V) ÷ Inverter efficiency (0.9)
Example: Load 1000W, backup for 1 hour, battery voltage 48V
Capacity = 1000 × 1 ÷ 48 ÷ 0.9 ≈ 23Ah
Rack-mounted UPS— Installed in a standard rack, space-saving, suitable for data centers and server rooms.
Tower UPS—Freestanding placement, flexible installation, good heat dissipation, suitable for offices, small server rooms, and industrial environments.
Recommendation: Choose a rack-mounted model if you have cabinet space; choose a tower model if there are no restrictions.
PUE（Power Usage Effectiveness） It is a metric used to measure the energy efficiency of data centers.
PUE = Total Energy Consumption ÷ IT Equipment Energy Consumption
Industry Standard:
Traditional data center PUE ≈ 1.8-2.5
Modular data center PUE ≤ 1.2(High efficiency and energy saving)
Sure! Most medium and large UPS systems support N+X parallel redundancy。
优点：
① Flexible expansion — Increase power as needed.
② High Reliability - A single unit failure does not affect overall operation.
③ Online Maintenance — Supports hot-swappable replacement.
Three mainstream air supply methods:
① Downward delivery, upward return. Underfloor air supply, commonly used, suitable for raised floor computer rooms.
② Upward delivery, downward return - Top air supply, suitable for computer rooms without raised floors
③ Horizontal air supply. —— Row-level air conditioning, delivering air directly adjacent to the cabinet, suitable for high-density scenarios
