Industrial Air Conditioner Sizing for Vietnam Factories: A Heat-Load Checklist | Qixin Tech

Author: Qixin Tech Editorial Team

Choosing an industrial air conditioner for a Vietnam factory is an engineering decision before it is a model comparison. This practical heat-load checklist helps purchasing and engineering teams prepare useful inputs, review airflow and agree how a proposed solution will be evaluated.

1. Define the Cooling Zone Before Selecting Capacity

Industrial air conditioner sizing for Vietnam factories should begin with a defined operating requirement. Are you cooling an enclosed production room, occupied workstations or a process area? A floor-area figure cannot answer this question. Mark the required cooling zone on a layout and state where temperatures will be evaluated.

An open workshop and an insulated room can require very different approaches even when their dimensions match. Record loading-door activity, connections to adjacent spaces and the normal ventilation arrangement. Ask the manufacturer whether the proposal is intended for spot cooling or room-wide temperature control.

2. Build a Heat-Load Input Sheet

List room dimensions, ceiling height, roof and wall construction, glazing and exposure. Add machinery, lighting, occupancy and operating schedules. Identify which equipment releases heat into the room and which rejects heat elsewhere. Avoid treating electrical nameplate power as a confirmed room heat gain without checking the operating process.

For a Vietnam project, provide local site measurements and the outdoor design conditions used by the responsible engineer. Identify normal conditions and the worst credible operating combination. Mark uncertain inputs so the supplier can explain how they affect selection instead of hiding them in an unexplained safety margin.

3. Plan Air Distribution and Heat Rejection

Cooling capacity and airflow distribution are separate checks. A unit can be appropriately sized while its air path is blocked by storage racks or machinery. Identify inlet and outlet positions, obstructions and the distance to the occupied zone. Ask for the proposed equipment positions on the layout.

Also confirm how heat leaves the system. The required utilities and heat-rejection arrangements depend on the exact equipment configuration. Do not assume that positioning a cabinet in a workshop completes the installation. Follow the approved model-specific drawings and maintain service clearances.

4. Match the Configuration to the Layout

Qixin Tech is a manufacturer based in Ningbo, China. Its industrial air conditioner range includes cabinet, hanging, jet, duct-connected and mobile configurations. Discuss these options with the supplier against your layout rather than treating them as interchangeable capacity ratings.

A vertical cabinet unit can be reviewed where a floor-standing position is available. If floor space must remain clear, discuss a hanging arrangement and have the mounting structure reviewed. Where ductwork is proposed, require airflow and external static pressure to be checked together.

5. Compare Proposals Under the Same Conditions

Ask each supplier for cooling capacity, electrical input and relevant operating limits at stated conditions. Compare the same indoor and outdoor assumptions, operating hours and included accessories. A catalogue rating without its test basis is insufficient for a final project approval.

Separate equipment price from installation, controls, supporting utilities, freight and commissioning. If an energy-saving target is proposed, define the baseline and measurement method. Neither a low purchase price nor a large nominal capacity demonstrates a lower operating cost.

6. Agree the Acceptance Test Before Ordering

Define the measurement locations, operating mode, evaluation period and acceptable conditions before production. Record door activity, ventilation and machinery use during the site test so the results can be compared with the approved selection assumptions.

Include operator training, maintenance access and document handover in the project plan. Ask which settings operators may change and who handles technical support. Keep outstanding items on a written list with an owner and a due date.

Frequently Asked Questions

Can I select an industrial air conditioner using square meters alone?
Area is an initial input. Confirmed selection also requires heat sources, room height, ventilation, outdoor conditions and the intended cooling outcome.

Does a larger unit always perform better?
No. The selection must match the load, controls and air distribution. Ask the engineer to explain both the capacity and its operating range.

What should I send for a quotation?
Send the factory location, layout, dimensions, heat sources, operating schedule, target conditions, electrical supply and installation constraints. Use the industrial air conditioner RFQ checklist to prepare comparable inquiries.
