Residential HVAC System
Summer comfort is becoming more and more of a concern for house designers and their residents. New buildings, often designed to limit heat inputs through passive solutions, reduce heating requirements. But the problem of cooling persists. Some ways to remedy this follow.
If the most obvious way to cool down a dwelling is to prevent the heat from entering it, in fact it is a little more complicated. Indeed, many recent constructions do not have an effective protection against heat, because often they have large windows or do not have blinds or shutters. Efforts are nevertheless made on this point and make it possible to implement passive solutions during the design. The orientation of the house, in particular, is an important factor to take into account, especially for the distribution of openings. The design of the glazed surfaces must also be carefully considered, because it is through them that 2/3rd of the heat made in summer comes in, as well as their protection in order to avoid summer overheating, limit winter losses, ensure good ventilation and provide sufficient light to limit artificial lighting. Exterior guards appear to be the most effective: roller shutters, swing shutters, sun shades, blinds or even solar shading
