Important Facts About Thermal Energy

Thermal energy or heat energy can rise and fall with temperature. Our daily life is deeply affected by it. In simple words it is “heat” that makes our life comfortable in many different ways.

Weather effect

You must have noticed that thermal energy is at its peak in summers. Therefore, we need to have cooling system inside our homes and buildings. During winter, situation is reversed. There is less thermal energy; therefore heating appliances are required inside rooms to keep us warm and cozy.

The source

Sun is the main source of heat energy. It might surprise you that even in cold winter; sun throws sufficient thermal energy to our planet. How this heat enters our homes while snow covers all around? It comes inside from building materials, windows and sky lights.

Geothermal energy

Just a few feet below the surface, earth has constant temperature. During winter, it’s warmer than its surface and during hot weather, its cooler. It gives heating source that is termed as “geothermal energy”.

Main uses 

Thermal energy is used in various ways in our daily life. It is consumed in the form of active gas, in solar and geothermal heating systems. Water heaters also have this energy. We can get more advantages from this energy by specifically designing our homes. It all depends upon our capability to get the most out of it.

Thermal water heaters

Many water heaters use thermal energy directly. These are compressed natural gas, butane, propane, oil, solar and geothermal. Waste heat or steam from a heater can also be used to warm drinking water at home.

Thermal space cooling

Thermally activated cooling systems (TACS) are type of solar space cooling system. Two types of solar systems are:

  1. Solar desiccant systems
  2. Solar absorption system

These work differently from one another. Desiccant systems regenerate desiccants which absorb humidity in the air. Thus, it creates cooler dry air.

Absorption systems work by absorbing solar heat. It then separates and evaporates refrigerant fluid. Thermal cooling systems are quite expensive and difficult to install.

Advantages

A great advantage of thermal cooling systems is that these are cost-effective. There is considerable reduction in energy bills. These are environment-friendly too.

Thermal space heating

There are many ways to control home temperature through thermal heating. It can be done actively by using liquid or air-based thermal space heating system. Another way is passive. In homes, windows can be designed facing towards south side. This will help keep rooms warm on northern winter days. This is because there is less sunlight in the southern sky during that time.

Thermal products

Three main home applications for thermal systems are hot water, heating and cooling system. These comprise of essential components and accessories. Various attachments are also included to make system work more efficiently.

These can be in the form of single room unit or for the entire house. Various types are solar thermal, radiant floor heating, gas-powered and geothermal. Some of the products used are controllers, pumps, expansion tanks, collectors, insulation and PEX tubing.
