Research Methodology for the United States Chillers Market
The United States Chillers Market should be defined as the revenue generated from the sale of chillers used to produce chilled water or other cooling fluids for commercial, industrial, institutional, healthcare, data center, and other applications.
The market should include air-cooled chillers, water-cooled chillers, centrifugal chillers, screw chillers, scroll chillers, reciprocating chillers, absorption chillers, and other chiller technologies according to the defined scope.
The market should be segmented by chiller type, technology, cooling capacity, application, end user, and geography. The scope should clearly distinguish chillers from packaged air-conditioning systems, cooling towers, heat pumps, and other HVAC equipment to avoid double counting.
The first step should be to estimate the number and floor area of buildings that could require centralized chilled-water cooling.
The analysis should cover:
Building stock, floor area, construction activity, and equipment characteristics should be used to determine the addressable chiller installation base. DOE's Building Performance Database provides information on commercial and residential building characteristics, including building type, location, size, age, equipment, and operational characteristics.
Not every commercial or industrial building uses a chiller. Therefore, a chiller penetration rate should be applied to the addressable building stock.
Chiller-Using Buildings = Addressable Buildings X Chiller Penetration Rate
Penetration should be estimated separately by building type because large hospitals, data centers, offices, hotels, and industrial facilities have different cooling-system requirements.
The analysis should also consider building size because centralized chillers are generally more relevant to larger cooling loads.
The installed base should be estimated in both units and refrigeration tons.
For each building category:
Installed Chiller Capacity = Number of Chiller-Using Buildings X Average Chiller Capacity per Building
The installed base should then be divided into capacity categories such as:
Capacity segmentation should be adjusted to the available manufacturer and industry data.
A significant portion of the U.S. chiller market comes from replacement of existing equipment.
The replacement market should be calculated using:
Annual Replacement Units = Installed Chiller Base ÷ Average Chiller Replacement Cycle
The replacement cycle should be differentiated by chiller technology, operating environment, maintenance quality, and application.
Older chillers should also be evaluated for replacement because energy efficiency improvements can provide an economic incentive for upgrading existing equipment.
DOE's FEMP guidance explicitly evaluates chiller purchases using lifetime energy costs and efficiency improvements, demonstrating the importance of replacement and efficiency economics in the chiller market.
New building construction should be modeled separately from replacement demand.
New Chiller Units = New Chiller-Using Buildings X Average Chillers per Building
New construction demand should incorporate:
The number of new buildings should then be converted into chiller units and cooling capacity.
The market should be divided among:
Air-Cooled Chillers
Estimate installations using air-cooled systems and multiply the number of units by their average selling price.
Water-Cooled Chillers
Estimate water-cooled installations separately, considering the larger cooling loads and associated infrastructure.
Centrifugal Chillers
Estimate demand primarily from large commercial, institutional, industrial, and other high-capacity applications.
Screw and Scroll Chillers
Estimate installations in smaller and medium-capacity applications.
Absorption Chillers
Estimate installations associated with applications where thermal energy or waste heat can be used for cooling.
DOE's current acquisition guidance distinguishes air-cooled chillers from water-cooled positive-displacement and centrifugal chillers and provides different efficiency requirements according to capacity and operating conditions.
The average selling price should be calculated for each chiller category rather than applying one price across the entire market.
ASP = Chiller Equipment Revenue ÷ Number of Chillers Sold
ASP should vary according to:
The calculation should distinguish equipment selling price from installation, engineering, maintenance, and other services unless those services are explicitly included in the market definition.
The core market value should be calculated using unit sales and ASP.
U.S. Chillers Market = Σ (Chiller Units Sold by Type X Average Selling Price by Type)
Alternatively, where reliable capacity data are available:
Market Value = Σ (Cooling Capacity Sold in Tons X Average Revenue per Ton)
The unit-based approach should generally be preferred because ASP varies considerably across chiller capacity categories.
The total market should be divided into:
New Installation Market
= New Construction Units X ASP
Replacement Market
= Replacement Units X ASP
Total Chiller Market
= New Installation Market + Replacement Market
This distinction should be maintained throughout the historical and forecast periods because construction cycles and replacement cycles can behave differently.
Manufacturer shipment data should be used to cross-check estimated unit volumes.
AHRI publishes U.S. heating and cooling equipment shipment statistics and maintains historical shipment information. Its statistical resources are useful for establishing manufacturer shipment trends and industry activity.
Where dedicated chiller shipment data are unavailable publicly, AHRI information should be combined with manufacturer disclosures, industry datasets, distributor information, and company-level estimates.
Major chiller manufacturers should be analyzed individually.
The analysis should cover:
The U.S.-specific share of each company's chiller revenue should be estimated before aggregating company-level revenue.
This prevents global HVAC revenue from being incorrectly counted as U.S. chiller revenue.
The market should be divided into:
For each application:
Application Market = Number of Relevant Facilities X Chiller Penetration X Chiller Units per Facility X ASP
Data centers should be analyzed separately because their cooling requirements, redundancy requirements, and equipment specifications can differ significantly from conventional commercial buildings.
The end-user analysis should distinguish:
This helps distinguish direct equipment purchases from purchases made through contractors or distributors.
Chiller capacity should be reconciled with energy-performance requirements.
DOE's FEMP guidance distinguishes chiller efficiency requirements according to air-cooled versus water-cooled design, capacity, and full-load versus part-load operation. It also references AHRI 550/590 test procedures.
Efficiency trends should therefore be used as a validation variable for:
The market should be divided into:
Large projects may involve direct manufacturer or contractor procurement, while smaller chillers may move through distributors.
Channel shares should be estimated using manufacturer sales structures, distributor information, contractor data, and industry interviews.
New chiller demand should be compared with U.S. construction activity.
The analysis should consider:
The construction pipeline should be converted into potential chiller installations based on building area and cooling intensity.
The United States market should be divided into major regions or states.
A practical state-level approach could include:
Regional allocation should consider:
Climate and cooling demand should be incorporated because the intensity and type of cooling requirements differ across U.S. regions.
Trade data should be used as a supply-side validation.
The framework should be:
Apparent Domestic Supply = Domestic Production + Imports - Exports +- Inventory Adjustment
Relevant HS classifications should be carefully reviewed because customs categories can combine chillers with broader refrigeration or air-conditioning equipment.
Imported chiller units should be separated from components such as compressors, heat exchangers, pumps, and other HVAC parts wherever possible.
Historical market values should be reconstructed using:
Historical Unit Sales X Historical ASP
Historical unit sales should reflect:
Historical ASP should be adjusted for inflation, product mix, capacity, efficiency improvements, and technology changes.
The forecast should incorporate:
The basic forecast formula should be:
Future Market Size = Base-Year Market Size X (1 + CAGR) ^n
A driver-based forecast should then be used to validate the resulting CAGR.
The final U.S. chiller market estimate should be validated using three independent approaches.
Demand-Side Validation
Chiller-Using Buildings X Chillers per Building X Units Sold/Replacement Rate X ASP
Supply-Side Validation
U.S. Manufacturer Shipments + Imports - Exports + Inventory Adjustment
Top-Down Validation
U.S. HVAC Equipment Expenditure X Chiller Share
The three estimates should not simply be averaged. Differences should be investigated based on equipment classification, new versus replacement demand, manufacturer coverage, imported equipment, installation revenue, and whether the estimate includes services.
Core Formula
United States Chillers Market = Σ [(New Chiller Units + Replacement Chiller Units) X Average Selling Price]
Alternative Capacity-Based Formula
United States Chillers Market = Σ [Cooling Capacity Sold (Tons) X Average Revenue per Ton]
The unit X ASP model should be the primary methodology, while the capacity-based, manufacturer shipment, construction, and trade approaches should be used as independent validation mechanisms.
