Thermodynamic Heating

  • Thermodynamic Heating works on the principle of thermodynamics. Energy in the form of heat can be transferred between two different bodies (or a body and its surroundings) on the basis of temperature difference.

  • This means that the effect of thermal energy only takes place when there is a temperature difference. From this it follows that there can be no heat exchange between two systems with the same temperature. For example, the content of carbonated cold drinks in a warm room will eventually heat up to the same room temperature as a result of heat being transferred from the room to the drink through the aluminum can by conduction.

  • The same goes for thermodynamic solar energy, which works on the simple principle of capturing and exchanging energy, in this case heat, using a special environmentally friendly refrigerant instead of water.

  • Highly energy-efficient thermal solar panels, which more closely resemble a cross between a solar panel and an air source heat pump, are used to trap the surrounding heat, which in turn is used to heat water for space heating and hot water preparation in houses, offices, churches, logistics and industry objects etc.

  • Acting the opposite of a refrigerator, an environmentally friendly refrigerant with good thermodynamic properties, pumped through a thermal absorber, called a collector, as a pressurized cold liquid. Circulating inside the collector, it absorbs thermal energy from the surrounding atmosphere that has heated the collector plate, and as the temperature of the refrigerant increases, it evaporates, turning the refrigerant into gas.

  • In addition to being able to produce hot water up to 50 o C in the shade with very high efficiency and low energy consumption, hydrodynamic solar heating systems are now used in underfloor heating and radiator systems in many new homes as they are able to extract enough heat from atmosphere to warm the building to a comfortable temperature even on the coldest winter days.

  • The biggest advantage of a thermodynamic solar heating system is that, unlike traditional solar collectors which must be mounted on the roof in the direct field of view of the solar energy, the thermodynamic solar collectors can be mounted anywhere, vertically or horizontally, in or out of the shade because its ambient temperature is needed, not direct sunlight.

  • As the gas transfers heat to the water, it cools to a liquid state and flows back to the solar panel where the process repeats itself. Thus, the refrigerant cycle enters the solar collector as a cold liquid and exits as a gas, passing it through a compressor to concentrate the heat and pressure in the gas like in a heat pump, and then passing it through the heat exchanger which takes the heat in to heat the water when the refrigerant returns to a liquid state.

  • In general, the refrigerant circulates continuously through the compressor pump and an external electric power source to keep the temperature difference almost constant during both the absorption (evaporation) and the release (condensation) of heat, helping to improve system efficiency.

  • The use of refrigerant in solar collectors instead of water is the secret to the thermodynamic success of a solar heating system. The theory is that it makes it more efficient than traditional solar panels, especially when there is no direct sunlight, allowing for much higher efficiency at a much lower ambient temperature than conventional water-filled solar panels.

  • Moreover, our panels weigh much less.
