Ceiling Ducted All-In-One Heat Pump ERV for North American Apartment Projects
EXINDA AURA is a ceiling ducted all-in-one heat pump energy recovery ventilator designed for North American apartments, condominiums, high-rise residential buildings, boutique hotels and compact multi-room projects.
AURA combines heat-pump heating, cooling, fresh-air ventilation and energy recovery in one concealed indoor unit. It does not require a separate outdoor condenser, helping project teams avoid conventional apartment-level outdoor equipment on balconies, façades or rooftops.
AURA uses two engineered exterior duct connections for outdoor intake and exhaust. Final duct sizing, louver layout, static pressure, drainage and service access must be confirmed for each project.

Designed for Apartments Without Conventional Outdoor Condensers
Traditional split systems can create coordination challenges in apartment and high-rise projects. Outdoor condensers may be restricted by façade design, limited balcony space, rooftop access, architectural requirements or the practical difficulty of routing refrigerant line sets.
AURA provides a decentralized apartment HVAC approach. Each suite can have its own heating, cooling and fresh-air system while using a concealed ceiling installation and engineered exterior air ducts instead of a separate outdoor condenser.
| Project Requirement | How AURA Supports the Design |
|---|---|
| Clean Building Façades | Avoids a separate outdoor condenser at each apartment. |
| Limited Outdoor Equipment Space | Integrates heat-pump and ERV functions into one indoor ceiling unit. |
| Independent Apartment Controls | Supports apartment-level heating, cooling and ventilation control. |
| Fresh-Air Ventilation Requirements | Integrates outdoor-air supply and exhaust-air energy recovery. |
| Bathroom and Toilet Exhaust | Allows connection of bathroom or toilet exhaust ductwork. |
| Concealed HVAC Distribution | Uses ceiling ducts rather than visible room equipment. |
| Compact Multi-Room Layouts | Can distribute conditioned air through a project-specific duct design. |
| Retrofit Opportunities | Can be evaluated where exterior equipment placement or refrigerant routing is difficult. |
Heating, Cooling, Fresh Air and Energy Recovery in One System
AURA is not a standard ERV and not a conventional ductless air conditioner. It is an integrated apartment HVAC system that combines thermal comfort and ventilation functions in one ceiling-mounted unit.
| System Function | AURA System Role |
|---|---|
| Heating | Inverter heat-pump heating for apartment comfort. |
| Cooling | Heat-pump cooling for residential spaces. |
| Fresh Air | Filtered outdoor air supplied through the integrated ERV section. |
| Exhaust Air | Bathroom and toilet exhaust can be connected to the unit. |
| Energy Recovery | Exhaust-air energy is recovered through the ERV core. |
| Indoor Air Distribution | Supply and return air are distributed through ceiling ductwork. |
| Controls | Wall-mounted digital controller included; optional Wi-Fi and BACnet. |

Ceiling-Ducted Design for Multi-Room Apartments
AURA is designed for ceiling-ducted apartment layouts, including studios, one-bedroom apartments and compact multi-room suites. It can distribute conditioned air beyond a single room when the duct system is designed within the available airflow and external static-pressure range.
For project selection, the mechanical contractor should review the following items:
| Selection Item | What Must Be Confirmed |
|---|---|
| Heating and Cooling Load | Required capacity for each apartment or suite. |
| Indoor Supply Airflow | Total airflow, room distribution and supply air branches. |
| Indoor Duct Static Pressure | Pressure loss from ducts, fittings, diffusers, dampers, filters and sound control components. |
| Outdoor Duct Static Pressure | Pressure loss from outdoor intake and exhaust ducts, louvers and weatherhoods. |
| Outdoor Louver Layout | Intake and exhaust location, separation and prevention of airflow short-circuiting. |
| Bathroom Exhaust | Required exhaust airflow, duct routing and control sequence. |
| Ceiling Space | Unit height, duct depth, condensate drainage and service-access space. |
| Noise and Vibration | Vibration isolation, flexible duct connections and acoustic requirements. |
| Controls | Wall-controller location and any required building-control interface. |
| Service Access | Access for filter replacement, electrical maintenance and internal inspection. |
AURA fan curves and technical drawings are available to support project specific duct design and equipment selection.

Frequently Asked Questions
What is a ceiling-ducted all-in-one heat pump ERV?
A ceiling-ducted all-in-one heat pump ERV combines heat-pump heating, cooling, fresh-air ventilation and energy recovery in one indoor unit. It is designed for projects that need both apartment comfort conditioning and controlled outdoor-air ventilation.
Does AURA require an outdoor condenser?
AURA does not require a separate outdoor condenser. It is installed indoors and uses two engineered exterior duct connections for outdoor intake and exhaust. The exterior ducts and louvers must be designed for the specific project.
Can AURA provide heating, cooling and fresh air for one apartment?
Yes. AURA combines heating, cooling and ERV ventilation in one unit. Final selection depends on the apartment heating and cooling load, required fresh-air airflow, duct design and project conditions.
What is the difference between ERV airflow and outdoor heat-pump airflow?
ERV airflow supplies fresh outdoor air and removes exhaust air for ventilation and energy recovery. Outdoor heat-pump airflow is a separate, higher-volume airflow used for heating and cooling operation. Both air paths must be considered in the mechanical design.
Can AURA serve multiple rooms through ductwork?
AURA is designed for ceiling-ducted apartment layouts. Its final room coverage depends on the duct design, airflow distribution and available external static pressure.
What information is needed for AURA HPERV project selection?
Please provide the apartment schedule, floor plan, heating and cooling load calculations, fresh-air requirement, bathroom-exhaust requirement, duct layout, static-pressure calculation, outdoor louver arrangement, electrical supply and project location.
