Hotel · 06 Hotel VRF must cool a room when the guest is in and stay quiet at night. Aurum Prodest installs multi-zone with lobby, guestroom and conference scenes — one outdoor plant per wing, service without emptying the floor.
A guestroom needs a quiet indoor unit and a simple control, not a 20-button engineering remote. Ducted or wall units in night mode, extra drain, pipes in boxes that do not vibrate the bed wall. Diversity follows occupancy, not 100% rooms at max all day.

Lobby and restaurant peak at meal times. Do not share the same branch as silent rooms. We split circuits or outdoor modules. Lobby cassettes follow the ceiling design.
A central controller for engineering: faults, filters, empty-room off. Key-card integration is a hotel brief, not every brand out of the box. Summer check-in and banquets get a cooling margin.
Live hotels install by wing on a reception timetable. Commissioning includes a night noise test. 5-year workmanship. Service off-peak.
Old wings may keep splits until a capex cycle. We write the hybrid in the brief so engineering is not surprised at handover.
VRF/VRV brands differ in service, controls, and line maturity. Pros/cons help pick a platform for building and budget.
A brief comparison by class and use case — we match equipment to budget and site

| Brand | Class | Pros | Cons |
|---|---|---|---|
| | Premium | Mature VRV, strong commercial reputation | Price and certified installers matter |
| | Premium | City Multi: reliability and quiet indoors | High quote on large projects |
| | Premium | SMMS: efficiency and flexible piping | Costlier than mid platforms |
| | Premium | Stable on large sites | Less local “household” name recognition |
| | Mid-range | Multi V: features at a softer price | Service reputation younger than JP top |
| | Mid-range | DVM: flexible commercial budgeting | Behind premium on “resource benchmark” |
| | Best value | VRF when the budget is tight | Shallower service and maturity |
| Rooms | night noise first |
|---|---|
| Public | separate from sleep circuits |
| Control | controller + hotel brief |
| Install | by floor, reception diary |
| Service | off peak season |
| Work warranty | 5 years |
Sometimes. Quality splits can be cheaper. We count façade, power and service — we do not push VRF for its own sake.
Often pipe vibration or fan speed. We test night mode, not only catalogue dB.
If integration is in the brief. Otherwise the controller is for engineering, not the night shift.
Risky for noise and peaks. We usually split. Saving one module is not a design goal.
Daikin, Mitsubishi Electric, LG, Samsung and others — for parts in Uzbekistan.
Longer after finished ceilings. We lock dates with occupancy.
Multi-zone systems — 12 cities. Crew dispatch, contract, warranty.
