Blissful buildings with Heat Recovery Systems
Energy consumption is a key part of most human activities. This consumption involves converting one energy system to another, for example: the conversion of mechanical energy to electrical energy, which can then power computers, light, motors etc. The input energy propels the work and is mostly converted to heat or follows the product in the process as output energy. Energy recovery or heat recovery systems harvest the output power and providing this as input power to the same or another process.
There is a large potential for energy or heat recovery in compact systems like large industries and utilities. Together with Energy Conservation it should be possible to dramatically reduce the world energy consumption. The effect of this will then be:
1.Reduced number of coal-fired power plants
2.Reduced airborne particles
3.Slowing or reducing climate change
4.Lower fuel bills on transport
5.Longer availability of crude oil
6.Change of industries and economies not fully researched
A heat-recovery system captures a building exhaust air and reuses some of the energy to precondition the makeup air before supplying it to the building.
Air-to-air heat-recovery systems for comfort-to-comfort applications can in general be categorized as:
• Sensible heat (dry bulb only) systems
• Total heat (wet bulb – sensible heat plus latent heat) systems
Heat recovery ventilation, also known as HRV, mechanical ventilation heat recovery, or MVHR, is an energy recovery ventilation system using equipment known as a heat recovery ventilator, heat exchanger, air exchanger, or air-to-air heat exchanger which employs a counter-flow heat exchanger (countercurrent heat exchange) between the inbound and outbound air flow. HRV provides fresh air and improved climate control, while also saving energy by reducing heating (and cooling) requirements.
As building efficiency is with insulation and weather stripping, buildings are being made more airtight, and as a result less well ventilated. Keeping in mind the requisite of fresh air for all buildings, the need of HRV’s has become obvious. Opening a window does provide ventilation, but the building’s heat and humidity will be lost in winters and gained in summers, both of which are very much undesirable. In such a situation heat recovery systems provides an optimal solution with fresh air to breathe, better climate control and energy efficiency sustainability. HRVs help you build using concrete with a touch of nature into it.
