THERMODYNAMICS

In recent years, the steady rise in fossil fuel prices, the high level of environmental pollution, the increasing global warming , etc, have brought to light new technologies, such as the ones based on thermodynamics – discovered by French physicist Carnot in 1824 - so as to reduce the use or, in many cases, get rid of the traditional boilers.

For this environmentally-sensitive purpose there are alternative systems such as the ones which include thermal panels, heat pumps the geothermal and hydrogen systems, and finally the thermodynamic collector systems, a mix of traditional thermal panels and the well-known heat pumps. Under certain conditions the thermodynamic collector systems may generate up to an 80 percent energy saving against electric or fossil-fuelled heating systems. The thermodynamic systems can be applied in cases which require hot water up to 60 degrees Celsius, that is, radiant floor heating, fan-coil units, convectors, hot sanitary water, swimming-pool warming, etc.

WORKING PRINCIPLE

The thermodynamic heating systems are based on the laws of thermodynamics, because they take advantage of the physical properties of a gas. That gas, when changing of states (liquid-gas, gas-liquid), is used to transfer the heat absorbed by the collectors to the water we want to warm up. We use two well-known gases, 134-A and 407-C, both in accordance with the European regulations and two of the most popular today. Our system works similarly as a regular refrigerator. That is, it has a cold part, a hot part, and a gas compressor – we use the German compressor Copeland -. The cold part is comprised by the collectors, and the hot part by the heat exchanger.

SYSTEM DESCRIPTION

The equipment consists of the following items:

• The hot sanitary water equipment includes a thermo-accumulator, a serpentine heat exchanger, a thermodynamic block and the collectors.
• The space heating equipment includes a high-efficiency plate heat exchanger, a thermodynamic block and the collectors.
• The swimming-pool heating equipment includes two titanium tubular heat exchangers, a thermodynamic block and the collectors.
