Energy Recovery Ventilator
Energy Recovery Ventilators (ERVs)
Energy recovery ventilators (ERVs) are designed to provide fresh outdoor air while recovering energy from the exhaust air. By transferring heat and, where supported by the recovery core, moisture between incoming and outgoing air streams, ERVs help reduce ventilation-related energy loads.
Sunchine ERVs can be configured for different building ventilation requirements, with options for airflow capacity, heat recovery core, filtration, fan selection and unit installation. The equipment can be tailored to project-specific requirements for commercial buildings, offices, hotels and other facilities.
With flexible configurations and engineering support, we help contractors and project owners select suitable energy recovery ventilation solutions for their applications.

How Energy Recovery Ventilator Works
Integrated temperature and humidity control for stable indoor environmental conditions.
1. Fresh Air Intake
Outdoor air enters the ERV through the intake duct and passes through a filter to remove airborne particles.
2. Heat & Moisture Recovery
As outdoor air passes through the energy recovery core, heat and moisture are transferred between the incoming and outgoing air streams, depending on the core type and operating conditions. This helps reduce the energy required for indoor climate control.
3. Fresh Air Supply
The filtered and pre-conditioned outdoor air is delivered into the building, helping maintain indoor air quality while reducing ventilation-related heating and cooling loads.
4. Exhaust Air Discharge
Stale indoor air passes through the recovery core, transferring energy to or from the incoming outdoor air, before being discharged outside. The two air streams remain separated within the core.

What is an Energy Recovery Ventilator (ERV)?
An Energy Recovery Ventilator (ERV) supplies fresh outdoor air while recovering energy from exhaust air. Depending on the recovery core, it can transfer heat and moisture between the incoming and outgoing air streams, helping reduce ventilation-related heating and cooling loads while supporting indoor air quality.
What is the difference between an ERV and an HRV?
An ERV (Energy Recovery Ventilator) can transfer sensible heat and, when supported by the recovery core, moisture between incoming and outgoing air streams. An HRV (Heat Recovery Ventilator) primarily transfers sensible heat. The appropriate system depends on the project’s climate, indoor humidity requirements and ventilation design.
Can ERVs be customized for different projects?
Yes. ERV configurations can be tailored to project requirements, including airflow capacity, recovery core selection, filtration, fan configuration, external static pressure, electrical specifications and installation arrangements. Final options are determined according to the selected model and project conditions.
What airflow capacities are available?
Available airflow capacities depend on the ERV model and configuration. To help us recommend a suitable unit, please share the required airflow, building application, duct resistance or external static pressure, and any specific ventilation requirements. We can then review the appropriate configuration with you.
Can you provide technical drawings and product specifications?
Yes. We can provide relevant product specifications and technical documentation for the selected model according to project requirements. Please share your airflow requirements, installation conditions and other relevant design information so we can confirm the suitable configuration and available documentation.
