Heating, Ventilation and Air Conditioning

They are the proceedings relating to the regulation of environmental conditions to make more comfortable the climate of dwellings or industrial purposes.
Heating obviously raises the temperature in a given space, with respect to atmospheric temperature, to a satisfactory level.

Ventilation systems control the supply and outlet air, independently or in combination with heating or air conditioning systems, to provide oxygen to the occupants of the premises and eliminate odors.

Air conditioning systems control the atmosphere of the interior space: temperature, humidity, flow and purity of the air, for the comfort of its occupants or to preserve materials that there are handled or stored.

Heating

The heating can be direct, as in the case of fireplaces or stoves in a room, or a central system with steam, hot water or hot air that runs through tubes and pipes to transport its heat energy to all the rooms of a building.

The first heating system was the bonfire, with which people heated their dwellings. The Romans developed stoves and braziers of different types, some of which are still used in many parts of the world.

PostHeaderIcon Which Type is Your Heating System?

There are many types of heating systems available. Which is yours? How does it work? What is its advantages and drawbacks? Here are the types and brief explanations of the systems:

  • Forced air system. The most broadly used type, because it’s the only heater that can be used for both heating and cooling and isn’t expensive. The air from the room is altered in the furnace, then transferred to the room through ductwork and registers. You may find some types of this system based on their fuel sources such as propane, natural gas, or electricity. Forced air system surely has many advantages. However, this system requires ductwork and some space in the walls. The air that is always moving also can be distributing allergens. Hence the air needs to be regularly filtrated and maintained.
  • Radiant heating system, provides the most natural heat. From pot belly stove to hot water tubing planted in the floor, the system transfers the heat by radiation or direct transfer from hot to cold surface. For the in-floor systems, it uses energy efficient boiler that heats water. As for the stove, it may use wood or coal. But you have to be patient if you use this system, because it takes a long time for the materials to be warm. You also have to spend a great deal of money to install radiant heating, and be prepared to spend some more if it experiences some problem, because the pipe is hidden.
  • Hot water baseboard system, heats water to heat a space. Similar to radiant heat, but this system also implements convection. There are some “fin-tubes” baseboard units that are fixed along the walls. These tubes will heat the air as the air rise with the heat that are produced by the hot water. Just like radiant heat, hot water baseboard system also takes a long time to heat the room. The baseboard radiation also requires some space and cannot be obstructed by furnitures. To transform the system to air conditioning, you must install another ductwork distribution and cooling system.heat
  • Steam radiant heating system, old system that is rarely used today. They come in two types, the one-pipe and two-pipe systems. The two-pipe systems separate water and system, unlike the one-pipe systems. Although they can warm spaces quite quickly, the radiators are not a nice sight and can limit furniture placement.
  • Geothermal heat pump (GHP), the newest technology of heating and cooling. It makes your home a refrigerator, but it can be reversed. The heat pump takes heat from the earth and also deposit it to the earth. The bad news is, these systems are expensive to afford.
