What the configuration numbers mean
The three-part labels give the numbers of heat pumps, heating tanks and storage tanks, in that order. The source workbook does not state whether the three sheets represent separate zones or alternative configurations.

Historical equipment prices
| Equipment | Archived unit price (CNY, excluding tax) |
|---|---|
| KFXRS-43II/CY heat pump | 22,800.00 |

Each total includes its scheduled equipment, pumps, controls, pipework, valves, insulation, electrical materials, installation and commissioning. Do not aggregate the three totals into one hotel project price.
Scope and exclusions
- Taxes, concrete equipment foundations, aluminum pipe jacketing and lifting costs are excluded.
- The client provides the main power cable and the hot-water, return-water and cold-water mains to the agreed connection points.
- A separate electric-heating control cabinet is optional and charged separately. Transport has a zero-valued line; confirm the transport arrangements in the project quotation.
Inputs for a revised configuration
- Number of users, peak demand periods, inlet-water temperature, required hot-water temperature and available operating hours.
- Storage and return systems to retain, installation space, electrical supply and pressure conditions.
- Responsibilities for lifting, foundations, pipe jacketing and main service connections.
These inputs affect heat-pump quantity, storage capacity, auxiliary heating and cost. An archived total should not be scaled solely in proportion to the number of users.

Questions about this reference
What does 3+3+27 mean?
It means three heat pumps, three heating tanks and 27 storage tanks. The corresponding archived quotation is CNY 235,318.50 excluding tax.
Do the three totals form one project price?
The workbook does not identify a combined project scope or explain whether the configurations are zones or alternatives. Each total belongs to its own schedule and should be used separately.
