What is Heat Recovery Ventilation?
The heat recovery ventilation(HRV) is a ventilation and air exchange device designed for indoor use. It enables consistent air exchange by continuously drawing in fresh outdoor air and expelling stale indoor air. Equipped with an internal heat exchange core, this unit recovers heat from exhaust air during ventilation. Compared with traditional ventilation equipment, heat recovery ventilation (HRV) can reduce energy loss while maintaining air circulation.
HRV ventilation systems are widely used in spaces that require a continuous fresh air supply, such as residences, apartments and office buildings. For compact areas or renovation projects, through wall HRV and decentralized HRV units provide a simple installation and efficient ventilation solution. They can achieve high efficiency of fresh air ventilation without complex ductwork.
Application of Heat Recovery Ventilation

Bedrooms
Installing our heat recovery ventilator in the bedroom can supply a continuous flow of fresh outdoor air and effectively remove stale indoor air. This maintains air freshness and improves bedroom air quality. The room heat recovery ventilator features a heat exchange core that minimizes heat loss during winter or cold weather air exchange. It helps maintain indoor temperature. The heat recovery ventilator also achieves silent continuous air exchange without disrupting sleep. The wall-mounted HRV features a compact structure and quiet operation, providing uninterrupted fresh air supply without affecting your sleep quality.
Living Rooms
Heat recovery ventilator is ideal for home public spaces like living rooms. As the primary area for family activities, living rooms are typically open and spacious. Traditional ventilation methods consume excessive energy, while opening windows for air circulation not only wastes resources but also causes temperature changes. As a residential heat recovery ventilator device, heat recovery ventilator can maintain air circulation and recover the heat. This solution improves air quality of your living rooms, reduces ventilation energy consumption, and helps maintain stable temperatures in the living area.
Offices
Commercial spaces such as offices and meeting rooms are typically crowded, requiring high standards for commercial ventilation. We recommend installing the heat recovery ventilator, which provide stable fresh air to maintain comfortable working environments and improve indoor air quality. Besides,it reduces HVAC operating costs for businesses. And the heat recovery ventilators can be integrated with central ventilation systems, making them suitable for high-frequency usage in commercial spaces.
Basements
Basements typically suffer from poor air circulation, making them prone to moisture buildup and mold growth. Therefore, the need for basement ventilation is quite obvious. Heat recovery ventilator effectively expel damp air from basements, enhancing air exchange. This reduces the buildup of humid air and improves the air quality in underground spaces. At the same time, the heat exchange core recovers some of the exhaust heat, which helps reduce heat loss and keep the basement temperature relatively stable.
Renovation
In renovation projects, installing complex traditional ventilation systems is often challenging due to structural limitations. Through wall HRV units provide a simple and efficient ventilation solution. This approach not only shortens installation time but also reduces overall renovation costs. It can achieve stable ventilation in existing homes without requiring major structural modifications.
Choosing the Right Heat Recovery Ventilation

Airflow Capacity
When choosing a heat recovery ventilator device, the first thing to consider is the size of your spaces and the required ventilation volume. Different space sizes and usage scenarios have different air exchange requirements. Generally, you should choose a heat recovery ventilator with an airflow corresponding based on the size of your usage scenario. If you have other special performance requirements, please contact us, Aosun will recommend the most suitable product for your project.
Installation Type
Heat recovery ventilator can be categorized into centralized HRV and through-wall HRV based on their installation method. The appropriate HRV installation method varies depending on the type of project. For residential, apartment, or renovation projects, we recommend installing through-wall HRV. It has a more compact structure and is generally easier to install. It achieves efficient fresh air exchange without the need for complex ductwork systems. For new residential projects, if a ventilation system is planned from the initial building stage, we recommend installing centralized HRV. They can provide a unified fresh air and exhaust solution for multiple rooms through a duct network.
Heat Recovery Efficiency
Heat recovery efficiency is a key performance indicator for HRV (Heat Recovery Ventilation) equipment. Higher heat recovery efficiency reduces energy loss during ventilation, thus improving overall energy efficiency. When selecting HRV models, we recommend prioritizing high-energy-efficiency models with heat recovery efficiencies exceeding 80%. Additionally, you should pay attention to the HRV’s energy efficiency rating and power consumption. Ensuring the heat recovery ventilator complies with local building ventilation and energy efficiency standards to meet the application requirements of different regions.
Noise Level
In spaces requiring quiet environments like bedrooms, living rooms, or offices, the operating noise level of the heat recovery ventilator needs to be considered. Low-noise HRV can provide a more comfortable environment while maintaining air exchange. You can choose a heat recovery ventilator model with an appropriate noise level based on the project’s usage environment to meet the ventilation requirements of different spaces.
Control Options
Heat recovery ventilator typically offer a variety of intelligent control options to meet the needs of different scenarios, such as homes, offices, and renovation projects. You can flexibly select different intelligent modules based on your project’s requirements, such as remote control, timer control, and multi-speed fan adjustment. Furthermore, some HRVs can be integrated with smart ventilation control systems for flexible and convenient mode switching and operation management. Please contact us if your project requires this service.
The main difference between HRV and ERV is the type of energy they recover during ventilation. An HRV (Heat Recovery Ventilator) transfers only sensible heat to keep indoor temperature stable without affecting humidity, making it ideal for cold and dry climates. An ERV (Energy Recovery Ventilator) recovers both heat and moisture, balancing humidity and improving comfort in hot and humid regions. We recommend choosing HRV for dry and cold areas, and you can select ERV for humid climates to achieve better indoor comfort and higher energy efficiency.
To ensure the effective ventilation of the heat recovery ventilator, the heat recovery ventilator’s filters require regular maintenance. Generally, We recommend cleaning the filters every 2–3 months and replacing them every 6–12 months. If the environment is dusty or humid, you should shorten the cleaning and replacement cycle. Regular maintenance the filters not only ensures efficient equipment operation but also extends the overall service life. It also can prevent issues like reduced airflow, increased noise, or higher energy consumption caused by clogged filters.
Yes. The heat recovery ventilator supports bidirectional ventilation. It supply fresh filtered outdoor air and exhaust stale indoor air simultaneously. The two air streams pass through the heat exchange core to transfer energy without mixing. The balanced design maintains stable indoor air pressure, avoids negative or excessive positive pressure, and ensures efficient and comfortable ventilation while maximizing heat recovery.
Whether to leave wall holes depends on the heat recovery ventilator installation type. Through-wall HRV needs reserved wall holes for fresh air intake and stale air exhaust. The ducted or ceiling-mounted HRV usually do not require exterior wall openings. We recommend confirming the installation type and dimensions before renovation or installation to avoid damaging finished interiors or increasing construction costs. You can contact us for professional guidance before purchasing.
With proper operation and regular maintenance, a heat recovery ventilator typically has a service life of 10 to 15 years. The main factors affecting the service life include the operating environment, the running time, the maintenance of filter and motor. You can effectively extend the service life of your equipment by regularly cleaning the filter, avoiding prolonged high-load operation, and keeping the equipment dry and clean. We recommend an annual basic inspection to maintain stable performance and reliability over time.
Not all HRV systems require ductwork. Whole-house centralized HRVs need ducts to distribute air to multiple rooms. However, through-wall HRVs and decentralized HRVs do not need any duct installation, making them simpler and more space-saving. They are especially suitable for bedrooms, small spaces, and home renovation projects. We recommend choosing the right type of the heat recovery ventilator based on your layout, area, and construction stage.
