Beginners Guide to Home or Office Climate Control
Climate control is a sophisticated form of heating and air conditioning. Standard air conditioning does not allow the user to set a specific temperature. It is just an input of cold air. Climate control sets a temperature and controls the air flow, as well as integrates it with a central heating system.
Humans are very sensitive to temperature, humidity and air quality. These parameters have to be within a narrow margin for comfort. The most comfortable range of indoor humidity should be between 30 and 60 percent. Temperatures should be between 22 and 25 degrees C. But buildings or cars can be located in temperatures ranging from minus 60 degrees C in polar regions to nearly 50 degrees C in places such as the Middle East during the summer months. Humidity in polar regions can be as low as in a desert while it rises to almost 100% in the tropics.
Heating, Ventilation and Air Conditioning (HVAC) systems maintain indoor air quality through air filtration and ventilation together with temperature controls. In general, HVAC systems draw air into a building to an air handling unit. Here it is filtered to remove particulates such as mould, dust and allergens and then heated or cooled. The resulting air is circulated through the building via a system of ducts. Separate fan coil units can be installed independently of the ductwork. They will heat or cool a specific area. The only downside is that they are noisy.
There are a wide range of electronic temperature and humidity controls. The hvac controls products include valves actuators, sensors and thermostats. They are easy to install and are state of the art technology. The thermostats may be programmable for use with heat pumps, unit heaters and fan coil units. Smart HVAC controls can save energy, cut costs and provide a high degree of comfort in the home. These devices can avoid the situation where one area could be heated and cooled at the same time. They can be programmed to heat a room only when it is occupied. And maintain a reasonably warm temperature in hallways. They can also be integrated into window locks and shut off any air conditioning when the windows are open.
Choice of system
Heating may be with heat pumps or combination furnace and central air conditioner. Heat flows from a higher to a lower temperature. Heat pumps use relatively little electric power to force the flow in the opposite direction. So they can transfer heat from the outside air into a building, or from the building to the outdoors. The advantage of a heat pump is that it can both heat and cool. The householder only has to maintain one machine. But combination systems have longer life spans as the furnace and air conditioner run on their own at different times of the year. Heat pumps are usually the best choice for regions where the climate is temperate and temperatures do not fall much below zero degrees C. A combination system is best for regions with long and very cold winters.
