Hello World! Welcome Friends! If you happen to see those big air conditioner boxes on top of offices or buildings, you will now know that these are part of the visible components of an HVAC system. HVAC is an acronym to mean Heating, Ventilating, and Air Conditioning. These are commonly used in industrial buildings, in apartment blocks, skyscrapers, and other large interior spaces and environments. It is also essential in environments where health regulations require certain levels of humidity and temperature.
HVAC is also the system used in regulating the temperatures in your own homes – either cooling or heating. The HVAC systems used in residences are just in a different form but it follows the same fundamental principles in its operations and their efficiency. Check https://en.wikipedia.org/wiki/Heating,_ventilation,_and_air_conditioning to learn more about HVAC.
HVAC Systems
Most often, heating and cooling a home is considered as half of the total energy used in the entire house. Having this in mind, it is important that when you choose an HVAC system for your home, you make sure that it will meet your expectations and deliver the comfort you need without it using too much power so that it inflates your living costs and expenses.
Families or individuals who live in places where there is almost only one kind of weather, hot or cold, would opt for a single-stage HVAC system, either it is designed for cooling or for heating only. This would seem to be inexpensive but sometimes inefficient because it will still be working in full capacity even when not necessary.
Some models that are more advanced would offer variable fan speeds so that power is cut down according to need but still this remains inefficient compared to a multi-stage system. In the long run, it will turn out to be just as expensive.
Some systems are zoned and are designed to heat or cool individual parts of your house. Zone valves and dampers are included in the vents and ductworks selectively block air flow. For large homes, this is a very efficient and valuable system as it only cools or heats places that are in use and it prevents the system from working in places that are not used.
Humidifiers and dehumidifiers can be added to these heating and cooling systems. Some people, especially those who live in the tropics or where there is a very dry environment find these add-ons essential and very helpful in ensuring their comfort. Humidifiers and dehumidifiers can be installed separately so it is easy for users to control the humidity in their homes.
Heating
Systems for heating homes come in two different forms. Some makes use of furnaces while some uses boilers. A furnace operates using propane or natural gas, while a boiler uses oil or gas to heat the water for steam.
One other option for heating is the use of a radiant floor or what is known as a hydronic heating system. Pipes that are filled with glycol solution or water are used under the floor. This can heat all kinds of floors and is efficient in keeping your home warm.
Cooling
Air conditioners come in varied forms and sizes. The ductless mini-split systems are the most popular kind. While many units can just be installed by homeowners, installation is still a big project as the exterior and interior elements need to be properly connected. Some systems need professionals to install them.
In places with dry climates, an evaporative cooler is more popular. This unit draws air from outside into the cooling system where it is cooled and moistened before being pushed into the living space; hot air is displaced in the process.
Types of HVAC Operations
Heat pumps – this works by extracting heat from outdoors and then it warms and releases the warm air into a room. Heat pumps use the same cycle as that in air conditioners but instead of releasing the warm air outside this is pushed inside. This kind of system can still be used to cool a room by reversing the air flow to push warm air outside instead of bringing it inside. However, the real value of this type is their heating power, it is more budget efficient than other traditional heating systems.
Rooftop units – these are also known as air handlers. These are huge systems placed on top of a roof in order to regulate the temperature of a big living space. The big boxes contain the blowers, cooling and heating elements, filters, dampers and chambers. This is where all connections from the internal element, the ductwork and the external elements are housed.
Split systems – this refers to air conditioning systems where the components are separated. There are two forms of the split system: mini-split and the central type.
Ductless types – this is the smallest type and is designed for single rooms or multiple small rooms. Installation requires minimum space and the compressor can be installed further away which allows more installation flexibility.
In choosing the best HVAC system for your needs, always consider to consult the experts like Lynn’s HVAC in Winnipeg who have been in the industry since 1980. The years of experience have made them an institution in the HVAC industry. The business is family owned and operations run by its hands-on owners. They cater to all kind of HVAC services and have a wide range of location coverage; hence, finding them will not be so difficult.
