Air-water, water-water and geothermal multifunctional units with high energy efficiency.

Europe is squandering its energy resources. Not only is money being waste, but harm is being done to the planet and is contributing to climate change. Currently, 80% of the energy resources used are derived from fossil fuels (oil, coal, natural gas) and the rest comes from nuclear, hydro-electric and biomass power plants, in more or less equal proportions. Fossil fuels (gas, oil and coal) are limited, not renewable, and therefore, exhaustible.

To obviate the problems resulting from shortages in and dependence on traditional energy resources, laws are being enacted in the EU to regulate the performance of heating systems in terms of efficiency and environmental protection, such as the Energy Performance of Buildings Directive (EPBD), the Ecolabel labelling and the REACH regulation. Indeed, the unstoppable process of globalisation makes it imperative to save energy to guarantee the survival of our planet.

HEATING SYSTEM Beyond heat Pump... multifunction technology

Multifunction units were born from the most modern ideas of comfort and are created according to the following fundamental criteria: system rationalisation and energy efficiency. Designed to satisfy system requirements for winter heating and summer cooling whilst simultaneously producing hot water, everything in a single device replacing all traditional mixed systems of a boiler + refrigeration unit and boiler + heat pump.

All of this drastically reduces both CO2 emissions from the use of primary energy and the machines’ operating expenses. The multifunction concept applies to the RESIDENTIAL AND LIGHT COMMERCIAL LINE as well as the HEAVY COMMERCIAL AND INDUSTRIAL LINE.

High values of TEP

With units able, simultaneously. to heat and cool, measuring efficiency through traditional EER and COP is limiting. In every case where the multifunction products produce heat and cool at the same time, the unit’s real efficiency is the sum of the heating and cooling services provided. To objectively measure the performance under contemporary load conditions, Thermocold, being at the leading edge in developing this technology, has created the TEP indicator - total efficiency performance. TEP coefficient represents the total seasonal efficiency of the unit calculated on the base of the efficiencies of each operat- ing mode of the unit and properly weighted (chiller, chiller + heat recovery, heat pump).

Therefore the TEP provide a more complete indication of the efficiency compared to traditional coffeicients such as EER, COP and seasonal one (ESEER). TEP is calculated as the ratio between the sum of thermal and refrigeration power supplied and the electric power consumed. TEP reaches its maximum value when the loads are complete- ly balanced, and it is the most effective way for representing the unit’s real efficiency. Multifunction products generally have TEP values of around 7.5. This means that for each Kw of electricity used, 7.5 kW of thermal power is produced.
