Everyone wants a home that's warm in the winter and cool in the
summer. Nobody wants a house that's cold in the winter and hot
in the summer. This is why many people decide to have central
heating and air conditioning systems installed in their homes.
But while this is a common decision to make initially, how each individual
homeowner proceeds will depend on their home, and how efficiently
it is able to retain energy. This presents the problem of
heat loss and heat gain, which must be considered
in order to design a heating, ventilation and air conditioning (HVAC) system
that will work in that specific home.
Heat
loss and heat gain in a home depends on a few factors. First, it depends a lot on the climate in the area. Those who live
in the desert are a lot more concerned with keeping the house
cool during a summer day than they usually are with maintaining
it warm at night. But they also must have their HVAC systems
to keep their homes warm in the winter, when desert climate can
fall to below zero. Conversely, those who live in
colder climes may be more focused on keeping their houses warm
in the winter, and may not be concerned about keeping cool in
the summer.
Another
component that will affect heat decrease and heat increasein
a home is how tightly sealed the house itself is. If it has
good, durable seals around windows and doors, and if the roof is strong,
and the windows and doors are insulated to sustain a constant
temperature, then it will be much easier for the HVAC system to
regulate the temperature of the home. But if the home is old and leaky,
and there are spaces under all of the windows and doors, the HVAC
system will have to work much harder to keep the temperature in
the home .
Insulation
will also influence heat loss and heat gain in a home. When your home
is well-insulated, it holds heat or holds cool, depending
on where you set the internal temperature of your home. Not only does it stop
air from leaking, but it also helps to maintain the air in
the home at a comfortable temperature for a longer time,
so that the HVAC system doesn't have to work as much to maintain
it. Whether it's summer or winter, insulation can help your HVAC system to be
more efficient.
