The art of heating ourselves and our surroundings is as old as mankind is and we have always been evolving new and better methods. We have gone from open-fires, to fire places and pot belly stoves to the very sophisticated heating systems for domestic homes and commercial enterprises.
Window units for air and space heaters emerged many years ago and are still in use today. More recently both have been operable through centrally located units, referred to as central heating and air circulation systems or HVAC (Heating, Ventilation and Cooling) systems.
Today though, we are all very much conscious of energy efficiency and of having a green attitude towards our environment, so many other ways to cool and heat our homes have been invented.
Heat pumps are an HVAC system that cools and heats your home by pulling heat in from the outside and circulating it throughout your home. Even though it may sound complicated, your home may not only be heated but can also be cooled by a heat pump.
A heat pump is a highly efficient operating system which can keep your energy bills much lower than a traditional central heating and air conditioning system. A modern machine will have a complex filtration mechanism, constantly cleaning the air in the room.
There are two types of heat pumps:
This is the more efficient style of heat pump. Depending on the heating load and temperature, this model of heat pump will adjust refrigerant so that less energy is lost by not having to restart the unit with every temperature change. This happens by the refrigeration cycle running at changing speeds to match the varying temperature changes.
Traditional Heat Pump
With this model, as the refrigerant goes between the compressor and condenser during the cooling cycle, the liquid turns to gas. When the desired temperature level in the home is reached, the refrigerant cycle stops. If the temperature in the home drops below the temperature on the thermostat or the outside temperature, it re-starts.
As the system stops and restarts to adjust the temperature, it is consuming more energy to cool or heat your home.
For generations people have used the only way they knew to get fresh air in their home, by opening up the doors and windows. That is fine if you don’t live in a heavily populated area with pollution from cars, factories and traffic, however, this is not really the best and most practical way to get fresh, clean air into your home.
As the seasons change, the open door and window method of airing isn’t always practical either. Apart from the fact that you may not be circulating clean air, the temperature can go from cold to hot and back to cold in such a short period of time. It certainly isn’t possible in the majority of commercial buildings either, since most have non-opening windows.
With the advent of modern technology, there are better ways to ventilate a stuffy house. You can enjoy the same effect as fresh air all year-round by installing a good filtered-air ventilation system. With this type of system, you can have fresh air in homes or commercial buildings all year-long, even in populated areas where there are more roadways and traffic.
With a ventilation system, polluted air inside the home or office is removed by a mechanical system and brings in the outside air that is clean and fresh. This provides the same results as opening all the doors and windows.
A ventilation system can be set up just for specific rooms or for your whole home. Not only does a mechanical ventilation system filter the air, but it keeps your home safe as you can close all the doors and windows making it secure against unexpected or uninvited guests. A home ventilation system reduces noise levels as well, a big plus for homes that are within the city and more populated areas.
A home ventilation system also decreases the likelihood of humidity and thus mold, due to the air being constantly moved through you home. With less moisture, the possibility of mildew is minimized, making the air in your home or a commercial building healthier to breathe.
In conclusion both systems are fairly efficient and each of them will achieve the desired result. They are both not inexpensive to install but are cheaper to run than alternative methods of climate control, are non-polluting will contribute positively towards our better health. A wise investment indeed!
