Types of ERV

Rotary Heat Exchanger (Wheel)

Wheels are the most popular ERV because of their relatively low initial cost, reasonable pressure drop, ease of maintenance and smaller physical footprint. This is a device, that can be either made of plastic or a type of metal, which rotates between the exhaust and outdoor air streams, meaning that it transfers heat energy that has been picked up from one air stream to the other. A plastic rotary heat exchanger are capable of absorbing and releasing moisture, while a metal one can only transfer heat.

Plate Heat Exchanger (Fixed Core)

These tend to be more expensive than rotary heat exchangers and have a larger physical footprint. Since they have no moving parts, this type of ERV may be more suited for places or certain applications in which a wheel is not permitted, such as a hospital. Instead of a wheel which rotates between the exhaust and outdoor air streams, a plate heat exchanger allows air streams to pass by each other through a series of channels, which heats up or cools down the material between the channels whilst transferring energy. These plates can be made of either metal, plastic or even paper.

Heat-Pipe Heat Exchanger (Refrigerant)

These heat pipes are made of copper and contain refrigerant within them. These pipes run between the exhaust air stream and outside air stream, and what happens is that one air stream heats the refrigerant, that is inside the pipes, causing it to evaporate. The refrigerant vapor moves down the pipe to the other air stream, which then cools the pipe and, hence, the vapor. As the refrigerant condenses, this warms the cooler air stream. The condensed refrigerant then flows back to the warmer air stream.

Runaround Coils (Water)

Runaround coils are similar to heat pipes, however they are often preferred when the exhaust air stream and the outdoor air stream are separated by large distances. Therefore, this would require installation of a water coil in each of the air streams. These two coils will then be piped together and filled with a water/glycol mixture. This mixture is then mechanically pumped between the two coils, enabling heat to be picked up in one air stream and released in the other.

Maintenance of ERV

ERV, also known as Energy Recovery Ventilator, is an integral part of a home's ventilation system. These systems are designed to improve indoor air quality by bringing fresh outdoor air while exhausting stale indoor air. To ensure the proper operation of an ERV, regular maintenance and upkeep are essential. Here is a technical guide to help you understand the maintenance and operation of an ERV.

Filter Replacement
The filters are recommended to be cleaned or replaced quarterly or semi-annually to ensure optimal airflow and prevent contaminants from entering the system. There are two filters to be replaced during the maintenance visit.

Heat Exchanger (The Core)
This component transfers energy from the outgoing exhaust air to the incoming fresh air. It should be inspected and cleaned once a year to ensure that it is functioning correctly and that there is no buildup of dirt or other contaminants.

Motor and Fan Assembly
The motor and fan are responsible for moving air through the system. They should be inspected and serviced as needed to ensure that they are functioning correctly and that there is no noise, damage or wear & tear.

ERV Controls
These components regulate airflow via a wall-mount control system. ERVs are designed to run continually at low speeds. Some units are equipped with wall Mount timers and speed controls. The switch offers three options for 20, 40 & 60 minutes ventilation periid. They should be inspected and adjusted as needed to ensure that they function correctly and that the system operates optimally.

Drain Pans and Condensate Lines
These components are responsible for collecting and removing moisture from the system, just like fan coils. They should be inspected and cleaned periodically to ensure that they are functioning properly and that there is no buildup of dirt or other contaminants.
