1. Scope and Applicability

This PCR governs production of marketable air-conditioning machines combining a motor-driven fan with elements that change air temperature and humidity, including machines without separately controllable humidity. It includes self-contained/window/wall/ceiling/floor, split/multi-split, ducted/rooftop and vehicle-passenger conditioning forms; reversible air-conditioning heat pumps and machines without an incorporated refrigeration unit are admitted. It excludes ventilation-only fans, standalone refrigerating/freezing equipment or heat pumps that are not air-conditioning machines, detached replacement parts, installation, use and end-of-life. CPC3 current labels, historical CPC2.1 correspondence and WCO scope are complementary evidence, not interchangeable editions.

The representative route is factory production of a declared vapour-compression configuration. Thermal absorption and externally supplied water/thermal coil configurations remain in scope when the delivered equipment satisfies the air-conditioning boundary; a standalone absorption chiller is not automatically an air conditioner. Declare the actual route: compression equipment needs its compressor and refrigerant circuit; absorption needs its actual generator/absorber, pump and working pair instead; external-coil machines may leave uncharged. Other emerging technology requires an explicit route-specific module/chemical inventory and evidence review, never borrowing a compressor BOM. Magnetic cooling in the manufacturer source is prospective.

Field	Value
Reference amount	1
Reference product flow	Accepted complete air-conditioning machine
Reference flow property	Mass `93a60a56-a3c8-11da-a746-0800200b9a66`

Reference unit	kg
Required qualifiers	model and delivered module schedule; stationary or vehicle application; conditioning function and fan; refrigeration-unit presence; vapour-compression, absorption or external-coil technology; cooling-only or reversible; compressor drive and inverter; coil materials and construction; rated cooling/heating capacity and test standard; refrigerant identity, blend composition and actual factory retained charge; dry or charged delivery; net mass M; declared factory starting state; make/buy boundary; factory geography, supply voltage and reference period; packaging schedule

Declare all qualifiers in the foreground data package; for dry external-coil routes record compressor/refrigerant fields explicitly as not_applicable with route evidence, distinguishing this from unknown identity or charge. Net mass M is measured for one accepted complete configuration, including all delivered modules and retained charge/oil, excluding packaging, installation additions, rejects and temporary test media. Never invent a machine weight or treat equal mass, rated cooling capacity or efficiency as equal delivered refrigeration service. For heterogeneous products normalize model-resolved records before aggregation; do not divide a mixed BOM by an unrelated average mass.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	reference product	Mass	kg	M = accepted net mass of one complete machine of the same configuration in kg; collect using cp_mass.
energy_units	Factory energy	Electrical energy or delivered heat	kWh; MJ	Retain meter units. 1 kWh = 3.6 MJ; cooling/heating capacity is a qualifier and is not electrical input. Steam conversion uses actual delivered/returned enthalpy.
species_balance	Charge and releases	Mass	kg	Balance each refrigerant or working-pair constituent by stock, receipts, retained accepted charge, sample/reject trapped charge, external recovery/waste transfer and measured release; unexplained residual remains a gap, not an assumed emission factor.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Purchased declared raw stock, components or complete submodules received at factory
starting_condition_role	Supplier-product interface; actual in-house manufacture starts here
product_classification_scope	Air-conditioning machines
recursive_input_rule	Purchased same-category machines/modules retain independent supplier burdens; internal rework/transfers are not new external supplies and cancel as exchanges
upstream_dataset_requirement	Match component state, technology, geography/year and actual supply interface; purchased compressor includes its motor and oil unless stated otherwise
disclosure	Factory gate includes all delivered modules/charge and separate packaging; installation, operation electricity/heat, use leakage and end-of-life excluded

rule_id	Applies to	Rule	source_ids
factory_scope	all processes	Include actual fabrication, joining, cleaning/finishing, assembly, evacuation/charging, leak/safety/functional tests, attributable rework, packaging and direct releases. Foreground starts at received stock/components; link upstream extraction/production/transport under declared provider boundary and include gate receipts not already covered. Exclude downstream installation and service energy.	`wco-hs84-2022`; `ipcc-ods-2006`
make_buy	fabrication; assembly	Build a component make/buy matrix: include purchased finished coil OR its in-house metal feed/forming/joining, never both for the same coil. Apply to compressor/motor/PCBA/cabinet and absorption modules. Additional supplier-completed operations are not repeated foreground burdens.	`daikin-technology-carbon`
route_scope	all processes	Use actual route conditions; no refrigeration unit does not mean no manufacturing burden, and a reversible air-conditioning heat pump is not excluded merely because it heats. An absorption cooling module is admitted only in a qualifying air-conditioning configuration with its fan/conditioning function. Record omitted operation evidence and actual other technologies before reuse.	`wco-hs84-2022`; `doe-hvac-2011`

Dry-delivered external-coil machines do not acquire fictional refrigerant charge.	Manufacturing foreground	1 kg reference flow
acceptance	Electrical safety, leakage and functional acceptance	required	Record actual leak/safety/functional test sequence and rework. Reversible models test declared modes; absorption tests record actual thermal supply; external-coil tests record supplied hot/chilled water. Destructive sampled units are not accepted sale output.	Manufacturing foreground	1 kg reference flow
dispatch	Final protection, packaging and factory release	required	Verify complete delivered sales configuration, including every specified indoor/outdoor module or vehicle-conditioning unit; weigh net equipment, retained charge and packaging separately. Record actual dry/charged release state.	Manufacturing foreground	1 kg reference flow
services	Shared utilities and pollution controls	required	Allocate actual compressed-air, vacuum, cooling-water and effluent/air-control burdens once. External purchased compressed air or supplied test heat is distinct from internally generated utilities.	Manufacturing foreground	1 kg reference flow

Each card is one physical exchange. Apply route conditions before collection; missing UUID/quantity never means zero. Extend cards for actual additional alloys, refrigerants, coatings, wastes and emitted species. Cancel internal transfers; do not map a gross generic subassembly to the finished reference product.

System boundary rules · 3

Rule ID	Applies to	Rule	Source IDs
`factory_scope`	all processes	Include actual fabrication, joining, cleaning/finishing, assembly, evacuation/charging, leak/safety/functional tests, attributable rework, packaging and direct releases. Foreground starts at received stock/components; link upstream extraction/production/transport under declared provider boundary and include gate receipts not already covered. Exclude downstream installation and service energy.	wco-hs84-2022, ipcc-ods-2006
`make_buy`	fabrication; assembly	Build a component make/buy matrix: include purchased finished coil OR its in-house metal feed/forming/joining, never both for the same coil. Apply to compressor/motor/PCBA/cabinet and absorption modules. Additional supplier-completed operations are not repeated foreground burdens.	daikin-technology-carbon
`route_scope`	all processes	Use actual route conditions; no refrigeration unit does not mean no manufacturing burden, and a reversible air-conditioning heat pump is not excluded merely because it heats. An absorption cooling module is admitted only in a qualifying air-conditioning configuration with its fan/conditioning function. Record omitted operation evidence and actual other technologies before reuse.	wco-hs84-2022, doe-hvac-2011

Allocation rules · 2

Rule ID	Applies to	Rule	Source IDs
`allocation_driver`	shared utilities	Subdivide metered processes first. Allocate shared services by documented physical causality: actual machine time/load, test-bench energy/time and processed material when demonstrated. Capacity ratings or finished mass alone do not prove causality. If other allocation is necessary justify it and test sensitivity; allocations sum to observed totals.	ef-allocation-2021
`recovery_and_rework`	charge; fabrication; acceptance	Keep rework and retest energy/materials in accepted-output burden. Internal refrigerant recovery reduces fresh demand through inventory balance, not negative virgin production; separately identify external reusable product and hazardous waste. Scrap sales alone do not establish co-product status or avoided-material credit. Apply the declared recycling treatment once.	ef-allocation-2021, ipcc-ods-2006

Validation rules · 4

Rule ID	Applies to	Rule	Source IDs
`reference_check`	reference_product	M must be positive calibrated net mass for exactly the declared delivered configuration; kg normalization, per-unit BOM/test records and all module/charge quantities share this denominator. Net product excludes packaging, temporary test media and destructive rejects.
`no_double_count`	all inventory rows	Check make/buy exclusivity, compressor motor/oil inclusions, internal transfers/recovery, accepted versus rejected counts, repeated tests and energy meter coverage. Purchased heat/steam and externally generated compressed air cannot duplicate the same supply. No use-stage electricity or leakage appears in factory totals.
`balance_check`	charge; fabrication; services	Reconcile species charge, material scrap, water and accepted mass balances with measurement uncertainty. Charge retained in equipment is not an elementary air release; external waste or recovered product is not release by default. Investigate unknown residuals and missing identity; never fill with an unverified default leak rate, GWP or zero.	ipcc-ods-2006
`scope_check`	all processes	Verify technology and conditioning function independently from capacity labels. Distinct vehicle, reversible, absorption and no-refrigeration-unit forms require their actual BOM/test/charge conditions and source limitations; equal kg does not demonstrate equivalent cooling service.	wco-hs84-2022, doe-hvac-2011
