Waste Heat Recovery

This blog will focus on some in-home waste Heat Recovery Systems available to consumers out there. While Perceptive Industries has a high client base in businesses and manufacturers, we support home heat recovery systems and thermal energy optimization. We want to educate consumers about ways they can spread efficiency both at home, and then possibly take that knowledge with them into the workplace!

            The basic concept of a home heat recovery system is just like you’d expect. Energy recovery ventilation systems allow air to ventilate through a house in a controlled way, while minimizing energy costs. The reduction, or recovery, of the heat comes in different way for the winter (colder) and summer (warmer) months. In the winter, ventilated air is heated by transferring heat from warmer inside air being exhausted to the fresh (but colder) supply of air. Reversely, in the summer, the inside air cools the warmer supply of air outside to reduce ventilation cooling costs. These recovery systems end up more or less moderating, or in a sense, equalizing, and the temperature of air.

            There are really only two main types of home heat recovery systems: heat-recovery ventilators (HRV) and energy-recovery (or enthalpy-recovery) ventilators (ERV). Both kinds feature a heat exchanger, one or more fans that move air through the machine, and then some necessary controls that will vary according to application. There are some smaller models that you can install on a wall or window, but the majority of models is central, whole-house ventilation systems with individual duct system or shared ductwork.

So, what is the main difference, you ask? A heat-recovery and an energy-recovery ventilator vary in the way the heat exchanger works. With an energy-recovery ventilator, the heat exchanger transfers a certain amount of water vapor along with heat energy, while a heat-recovery ventilator only transfers heat. This makes some intuitive sense. The benefit of the water vapor being transferred along with the heat is that the humidity of the house also ends up being generally regular and maintained. It doesn’t mean that a heat only recovery system alters the humidity of the house, but it doesn’t do anything to maintain it. The options and applications are dependent on the consumer’s unique needs.

Look into these heat recovery systems for your home or workplace, and start saving!
