What this manufacturer offers
Zhongda Air Conditioning Group’s official site presents a broad central-air-conditioning business in Dezhou, covering main units, terminals, ventilation, cooling towers and associated products. Its reviewed water-cooled screw page is a catalogue family without a filled-in model or numerical selection table. That distinction matters when deciding whether to buy a machine or procure an installed cooling system.
An original August 2026 public-procurement notice names 中大空调集团有限公司 as the second-ranked candidate for a university kitchen ventilation and fume-treatment contract. It records relevant contracting qualifications for that competition. A candidate notice is not a completed project, a final award or a performance report for the water-cooled screw family.
The supplier publishes relatively specific service wording, including a 12-month warranty from successful equipment trial acceptance. Buyers should connect that wording to their actual delivery location, acceptance procedure and contract, especially where export installation and service are involved.

03 / PROJECT REVIEW
Zhongda combines equipment supply with an engineering role
Choose equipment-only or installed-system responsibilities
The site markets both HVAC equipment and engineering capability. A broad supplier catalogue does not identify everything included in a chiller purchase. Keep responsibility for plant design, cooling-water infrastructure, installation and commissioning explicit.
Equipment purchase
Request the selected chiller model, design-condition schedule, shipping configuration, accessories, controls interface and factory-test documents.
The notice published on 21 August 2026 concerns the second lot of the Beijing University of Science and Technology Xiong’an campus kitchen ventilation and fume-treatment systems. It lists Zhongda as second-ranked candidate and records Grade II general mechanical/electrical contracting and Grade I specialised building mechanical/electrical installation qualifications in its response table.
This is useful evidence of an engineering role at the time of that competition. It is deliberately not described as a final award, an independently verified installation outcome or a product certificate. Check current qualification documents and comparable completed references for the work being commissioned.
Recorded in the original notice
Exact company name, candidate ranking and qualification response are visible in the issuer’s public record.
Current certificate identity/scope, contracting entity, named project staff, completed acceptance records and the actual delivery/service boundary.
Read corporate scale and history as attributed claims
The official overview says the group began in 1994 and describes a substantial Dezhou campus, workforce and export activity. These are corporate statements rather than this platform’s current factory audit. The page mixes historical export information, headline category counts and a larger series/variety count in its prose; they are not a current model inventory or proof of available delivery capacity.
For a time-sensitive order, ask which site builds the chosen main unit, what production/test work remains and when the approved configuration can ship. Request a traceable order schedule rather than inferring lead time from group-wide scale. Its ISO9001/ISO14001 statements also need current certificate numbers, scope, sites and validity before becoming qualification evidence.
Water-cooled screw marketing does not complete a technical offer
The detail page describes a five-to-six asymmetric screw-rotor arrangement, capacity adjustment, microcomputer control, remote-control capability and ten self-protection functions. It does not identify the compressor make/model, refrigerant, controller protocol, protection schedule or rated performance. The product-model field is unfilled, and the parameter tab contains no readable numerical table.
The download centre lists a September 2022 electronic-catalogue test entry with a reference-only label. Its download link opens the same listing rather than a usable technical file. This review therefore has not obtained a complete selection catalogue. Ask for the current selected-model sheet and an agreed performance/test basis.
Distinguish warranty, response, arrival and repair
The service page states 12 months from successful equipment trial acceptance, with responsibility for qualifying product-quality problems. Its response wording promises two hours within urban areas, eight hours to arrive for repair, 24 hours to resolve faults without replacement parts and 72 hours where replacement is needed. Those stages and conditions should not be collapsed into a worldwide two-hour repair promise.
The site describes training at start-up and subsequent operator/technical training, technical support and visits after warranty. It does not establish that overseas travel, freight, customs, labour or replacement parts are free indefinitely. Agree the service party, geographic coverage, charges, stock, escalation and warranty start/acceptance records in writing.
Record the start event
Define trial acceptance, sign-off documents and handling of delayed installation before applying the published 12-month period.
Agree response versus arrival, working hours, destination access, competent local support and responsibility for parts logistics.
Record handover and exclusions
Retain model/serial and operating records, training and commissioning reports, applicable warranty exclusions and post-warranty charges.
