Focus Area – Cooling & Thermal Efficiency
Thermal energy storage is like a battery for a building’s air-conditioning system. It uses standard cooling equipment, plus an energy storage tank to shift all or aportion of a building’s cooling needs to off-peak, night time hours. During off-peak hours, ice is made and stored inside IceBank energy storage tanks. The stored ice is then used to cool the building occupants the next day.
The Ice Bear 30 is an intelligent, distributed ice battery for 3-20 ton commercial
air conditioning units. During off-peak hours, it stores cooling energy by freezing water in an insulated storage tank while the conventional AC provides cooling as needed. During peak hours, ice-chilled refrigerant circulates from the Ice Bear 30 to the air conditioning system, eliminating the need for energy-intensive compressors.
Ice Bear charges by making ice during off-peak hours and discharges by using the stored ice to cool buildings during peak hours. Our smart Ice Bear battery reduces peak cooling electricity by 95% for up to 6 hours a day, every day.
M-Cycle Pre-Conditioning or Cooling is a proven Energy Efficiency solution, with over 2,000 installations in Americas, Europe and Far East
Huge amount of energy is wasted through inefficient A/C distribution:
Stratification, i.e. the iso-thermal layering of the air has been recognized as another leading root cause for HVAC and hence Energy inefficiencies
Heat pumps provide heating, cooling and sanitary hot water for residential, commercial and industrial applications. They convert ambient energy from air (aerothermal), ground (geothermal) and water (hydrothermal) but also excess heat from buildings and processes to useful heat. This conversion is done via the refrigerant cycle, which is also used in refrigerators and air conditioning systems. Heat pump technology is efficient and mature.
A heat pump system consists of a heat source, the heat pump unit and a system to distribute heating and cooling.
The heat pump works as follows: (1) a transfer fluid (refrigerant) is exposed to the energy source, where it evaporates and thus cools the source. Using a compressor (2), the refrigerant vapour is compressed and its temperature increased. In the next step (3), the high temperature – high pressure vapour – is fed into a heat exchanger where the energy is transferred to a distribution system. The vapour cools down and condenses. After the pressure is released in an expansion valve (4), the liquid is exposed to the heat source again and the cycle is closed. Heat pumps always provide heating and cooling at the same time. In the heating mode, outdoor ambient energy is the heat source and the building/process is the heat sink. In the cooling mode, the building/process is cooled down using the outside as heat sink. Highest efficiency is reached when heating and cooling is needed at the same time.
Adsorption chiller, any device designed to cool interior spaces through adsorption, a process that uses solid substances to attract to their surfaces molecules of gases or solutions with which they are in contact. Instead of using large amounts of electricity, the cooling process in an adsorption chiller is driven by the evaporation and condensation of water. Adsorption chillers provide an energy-efficient alternative to conventional refrigeration and air conditioning, because energy to drive the cooling system comes from water warmed by waste heat, such as exhaust or steam from industrial processes or heat directly generated from solar panels or other devices.
