Compare a water-cooled screw offer at the same design conditions
Hon Ming’s original detail identifies a water-cooled screw chiller and describes use in large air-conditioning or industrial refrigeration installations. It names commercial buildings, industrial sites, data centres and hospitals as application examples. The page does not publish an individual model, capacity range, refrigerant, electrical supply or numerical efficiency rating.
The main image shows a packaged machine with horizontal vessels and a control cabinet, but provides no readable model nameplate or rating schedule. It supports identification of the catalogue arrangement, not a performance calculation. The qualitative wording about efficiency, stability and flexible adjustment remains a manufacturer description without measured figures in the reviewed page.
Use this family reference to request a coordinated technical offer. An orderable unit needs a defined cooling duty, chilled-water and cooling-water conditions, electrical/control interfaces and an agreed boundary for the surrounding plant.
Published parameters and their scope
This is an equipment family; its range does not identify one orderable configuration.

| Parameter | Published value | Conditions and evidence |
|---|---|---|
| Official equipment type | Water-cooled screw chiller | Original catalogue names screw-compressor equipment; exact compressor/model/circuit configuration not supplied. Source |
| Published application examples | Large HVAC and industrial cooling; buildings, data centres and hospitals | Manufacturer application wording, not a project qualification or redundancy guarantee. Source |
| Individual rating status | No readable model or numerical selection table | Capacity, input, refrigerant and limits must come from the proposed model’s current documents. Source |
Selection and application review
The selection point is the first missing deliverable
A capacity quotation is useful only when its conditions match the project. Provide the required cooling duty and chilled-water supply/return temperatures, cooling-water entering/leaving conditions and duty profile. Ask the supplier to state flow, pressure drop, output and input for the selected model at that same point. The public family page supplies none of those numbers.
For process cooling, state temperature stability, operating hours and the proposed fluid composition. For a building, supply the design and partial-load schedule and intended staging. These are enquiry inputs, not evidence that the catalogue unit offers every requested temperature or control mode.
Keep the two water interfaces and the surrounding plant distinct
A water-cooled unit selection must be reconciled with the actual hydraulic design. Request a drawing and schedule that show what the manufacturer supplies and what the installer/system designer provides.
Cooling-water side
Request design and allowable cooling-water conditions, flow/pressure drop, connection and water-treatment requirements. Obtain the associated heat-rejection selection separately.
Plant equipment and controls
Define whether pumps, towers, valves, metering, supervisory control and commissioning are included. A group portfolio does not make them part of this family’s quotation.
Efficiency needs a measurement boundary, not a general adjective
The product page claims high efficiency but gives no COP, seasonal metric, test conditions or report. No numerical energy-saving percentage is established for this family. Ask for the selected unit’s full/part-load performance with its rating method and assumptions.
Keep unit input separate from whole-plant electricity demand and identify the equipment included in any claimed system result. If the offer includes an energy-performance commitment, agree the baseline, operating conditions, meters, calculation method and acceptance period. The platform has not measured a Hon Ming plant or verified an energy guarantee.
Check staging, operating limits and protection for the actual duty
The listing’s “flexible adjustment” wording does not identify capacity-control method, minimum load, turndown, restart sequence, circuit count or redundancy. These details matter when a large design duty is accompanied by long periods of smaller load.
Load and operating envelope
Request capacity steps/modulation, minimum stable load, permitted water/ambient conditions and selection curves for the project’s operating points.
Electrical and control interfaces
Request supply, current/starting schedule, electrical protection requirements, BMS protocol/point list, local controls and versioned wiring documents.
Protection and continuity
Request alarms, interlocks, flow/freeze protections and restart behavior. Agree any redundancy and maintenance strategy separately; the page does not promise uninterrupted cooling.
Group standards and tower history do not approve this chiller
Hon Ming’s history describes cooling-tower certification milestones, while the national standards platform names the group as a drafting organisation for GB/T 46752-2025 on integrated building cooling-source systems. Those are different scopes from this unnumbered screw-chiller family.
No current model-specific chiller certificate or performance report was established by this review. If a project requires a particular standard or approval, request the exact covered model/configuration, manufacturer/site, edition, conditions and issued evidence. Drafting participation alone is not a test pass. The linked factory review explains the original records and their limits.
Turn the technical offer into an installation and acceptance package
The detail does not specify dimensions, operating weight, refrigerant charge, service clearance or a current installation manual. Request these for the proposed unit and confirm access for placement, maintenance and the project’s water/electrical connections. Do not derive installation requirements from the photograph.
Before contract award
Approve the identified model, operating-point selection, delivered scope, electrical/hydraulic interfaces and applicable evidence.
Before delivery
Agree factory-test conditions, witness/inspection requirements, packing and installation drawings, document revisions and the responsible production entity/site.
At site acceptance
Agree commissioning checks and performance measurement at defined conditions, control integration, manuals, training, spare parts and support at the installation location.
