It is
always so nice to feel warm and cosy when it is chilling cold
outside. The heating and cooling systems (HVAC) can instantly help in
changing the temperature and make us comfortable at the place.
Does
it ever make you wonder the working of HVAC?
The
possibility of keeping you warm in the winters and cool in the
summers is because of the heat pumps that pump warmth from one place
to another. Heat Pumps are
attached to the HVAC system and rather have very simple
functionality. They take heat from the colder spaces and release it
into a warmer one.
They are
usually attached to radiators, underfloor heating systems, and warm
air convectors to maintain a desirable temperature in both
residential and commercial areas. They have amazing climate control
properties that can be reversed when one needs to cool the space.
With a
reverse functionality of a refrigerator, an air source heat pump can
absorb heat from the outdoors and transfer this heat energy in the
indoors of your house. Moreover, Electric Heat Pumps are a great
source of generating heat and their use in homes and offices has no
harm on the environment. Since they run on electricity, they do not
combust fuel and offer a fantastic way to lower the carbon footprint.
However, they can be less efficient in temperature below -15 C, they
are incredibly capable of managing room temperatures and offering a
warm and cosy space in your indoors.
Types of
Heat Pumps:
If you
want to know more about Heat Pumps, let us start by introducing you
to all types that are found:
The
air source heat pump
is best for a moderate and settled climate like in the UK. It can
simply be fitted i n the side of the building wall. The fan extracts
the outside air and transfers heat by compression of the coils made
up of conductive copper tubing.
An Air
Source heat pumps is a much more efficient way to heat up the space
by significantly saving on energy bills.
Apart
from the outside air, there are other means to draw exergy, one of
the major being the ground and water. Did you know, we can extract
the solar energy stored in ground and water to run ground source heat
pumps. They use the heat pipes that are laid into the soil and are
also called Geothermal heat pumps. Also, due to a constant ground
temperature, they have higher energy efficiency as compared to the
air source heat pumps.
3 Types
of Ground Source Heat Pumps:
- A horizontal array can be placed under the surface of your garden.
- A vertical heat pump can be placed several metres into the ground through a bore hole.
- Rather than the ground this kind of pump can use a localised water source to draw the heat from.
When
a heat pump is used in combination of other energy source like gas
boiler it generates a higher level of efficiency. These pumps are
called Hybrid Pumps and are perfect for heat generation in extremely
cold climates as there is no need to change radiators after you
install this heat pumps in your space.
Another
hybrid configuration is to have a mix of ground and air source heat
pumps that operate at full efficiency at different times of the day
or even throughout the year. So when the air is colder outside, it
draws on the ground source heat pump energy and when the air is
warmer it has a reverse operation.
The
Ductless Mini split is best when the area of heating is not large
enough as a building. These ductless mini split heat pumps do not
require duct to pass heat into rooms and are quite similar to the
ordinary air source heat pumps operating in a single room.
Moreover,
their small size also becomes a great advantage to easily install
this heat pump.
5. Absorption Heat Pumps
The
Absorption heat pump uses the solar-heated water or the geothermal
heated water to provide heat rather than the electricity. They are
also referred as the gas-fired heat pumps and are mostly used in
industrial processes in larger firms.
How
does a basic Air Source heat pump work?
The Air
Source Heat pumps are the most common heat pumps found in the UK.
This is solely due to the moderate climate of the UK that is not too
cold and not too hot. The Air Source heat pump is best to go for in
areas that have a moderate climate.
In
simpler words, a heat pump is a device that transfers energy from one
place to another.
Since,
heat moves from higher to lower temperature, so the heat pump follows
a reverse functionality using simple science which pushes outside
air, warms it up and then enters your living space.
The Air
Source Heat Pump has a refrigerant with a system of coils over which
an impeller or fan is used to draw air from the outside. The
refrigerant coil has a liquid that absorbs all the heat and
evaporates. By going through the compressor this gas then changes
temperature drastically.
The coil
then moves towards some inner coils where the heat is released. The
refrigerant meanwhile flows back outside where it picks up more heat
and the process starts again. The useful heat produced is pumped into
air ducts and is spread to various locations around the building or
can be used to heat water that feeds into radiators.

Taking care of your HVAC system is really necessary because as you are using your furnace, air conditioning and other appliances it goes dirty with the time. Filters needs change. And for better performance HVAC system must be inspected for any faults. Heating and Cooling Newmarket
ReplyDeleteInfrarood verwarming I am impressed. I don't think Ive met anyone who knows as much about this subject as you do. You are truly well informed and very intelligent. You wrote something that people could understand and made the subject intriguing for everyone. Really, great blog you have got here.
