WHY THERMAL COOLING SYSTEMS  for COMMERCIAL and INDUSTRIAL APPLICATIONS?

There has been an increasing demand to refrigerating, ventilating, cooling and air-conditioning the indoor environment of the houses, residential & commercial  units & buildings for decades. Nearly, 140 million air-conditioners are sold and installed annually in the world. Until now,  traditional or conventional air conditioners have been on duty for this purpose. Conventional air conditioners have significant disadvantages such as:

• Noisy operation

• High electricity consumption

• Disturbing chilled dry air

• Greenhouse Gas Emissions

• Use of Chemical Refrigerants

​However, Thermal Cooling Systems have significant advantages over conventional air conditioners, such as:

• Plug & Play  Energy Efficient Total Package

• Less Expensive & Cleaner

• High Savings by Utilizing heat instead of electricity as primary source

• Cooling & Heating gently without drying out the indoor air

• Cooling based on Thermal Energy, not electricity

• CO2 Reduction

• Increase of Operational Hours of CHP Unit

• Reduction of Electric Peak Load

• Use of Absorption Chillers (Solar & Waste Heat Powered)

• Use of Adsorption Chillers

Absorption Chillers vs. Compressor-based Cooling Systems

• less electricity consumption (>%75 saving)

• lower operating hours

• non-usage of refrigerants (CFCs & HCFCs) that damage ozone layer with greenhouse gas emissions

• usage of water as refrigerant 

• stable coefficient of performance (COP)

• lack of issues with mechanical vibration

• easy maintenance and longer life of operation

• No peak saving & significant reduction of total costs
