Energy recovery ventilators (ERVs) are mechanical ventilation systems, which remove polluted air from homes and replace it with fresh air. They are also known as air heat exchangers. Energy recovery ventilators should not be confused with heat recovery ventilators. In energy recovery ventilators, the heat exchanger transfers a certain amount of water vapor along with heat energy, whereas heat recovery ventilators transfer only heat. The system works on the principle that it cools and de-humidifies automatically during summer and pre-heat in cooler seasons. The benefit of using energy recovery ventilators is that they improve indoor air quality and reduce total HVAC equipment capacity. On the basis of technology, energy recovery ventilators are classified into plate heat exchanger, rotary heat exchanger, run-around coil, heat pipe heat exchanger, and others. Energy recovery ventilators are used primarily in commercial and residential construction. Rising demand for fresh air and necessity to reduce indoor pollutants are major drivers contributing to growth of the energy recovery ventilators market. Lack of awareness about advantage of energy recovery ventilators and high cost of the system are major restraints for the growth of the energy recovery ventilators market.

Out of all technologies of energy recovery ventilators, plate heat exchangers are most widely used. Plate heat exchangers is also likely to be the speedily growing technology segment of the market during the forecast period. A plate heat exchanger has no moving parts and it consists of alternating layers of plates, which can be separated and sealed. Another advantage of plate heat exchangers is that they provide an efficient mechanism of heat transfer along with maintaining temperature of the building constant. They have ability to recover more than 80% of the available waste exhaust heat. These advantages are likely to fuel the plate heat exchanger segment during the forecast period.
Construction application is expected to be the leading segment and also the speedily expanding application segment of the energy recovery ventilators market in the next eight years. Rising construction activities, implementation of stringent government regulations about environment and increase in awareness regarding HVAC systems are the key factors contributing to growth of the energy recovery ventilators market. Higher use of energy recovery ventilators in commercial buildings such as hotels, offices, gyms, restaurants, and laboratories in comparison to residential buildings is another factor driving the market. Usage of energy recovery ventilators for residential buildings is still at a nascent stage, but is expected to increase in future, due to rise in awareness about indoor air quality.
North America is anticipated to be the speedily expanding region for the energy recovery ventilator systems market, followed by Europe and Asia Pacific, during the forecast period. Recovering economy and increasing initiative by government and non-government organizations regarding adoption of energy recovery ventilators are anticipated to augment the market in North America. The federal government has already made it compulsory to install energy recovery ventilators in its buildings and also in schools and small businesses. Growing concerns about minimizing the cost of energy consumption are also estimated to drive the global energy ventilator systems market. Recovering European economy and increasing awareness about indoor air quality in Asia Pacific are expected to fuel the market in the respective region during the forecast period.
Key players operating in the energy recovery ventilators market include Mitsubishi Electric Corporation, Ltd., Reznor, Greenheck Fan Corp., Renewaire, LLC, Zehnder America, Inc., Nortek Air Solutions, Munters Corporation, and Ruskin Rooftop System.
