Walk-in, solar-powered cold stations - Controls & Cycle Optimisation (Cold Hubs)

ColdHubs, is a “plug and play” modular, solar-powered walk-in cold room, for 24/7 off-grid storage and preservation of perishable foods. It adequately addresses the problem of post- harvest losses in fruits, vegetables and other perishable food. ColdHubs, is installed in major food production and consumption centers (in markets and farms), farmers place their produce in clean plastic crates, these plastic crates are stacked inside the cold room. This extends the freshness of fruits, vegetables and other perishable food from 2 days to about 21 days. The solar powered walk-in cold room is made of 120mm insulating cold room panels to retain cold. Energy from solar panels mounted on the roof-top of the cold room are stored in high capacity batteries, these batteries feeds an inverter which in turn feeds the refrigerating unit.

Split path air conditioning - Air Handling (Toro Water Air Thermal Technologies Corp)

TORO WATT – a Canadian HVAC technology company based in Ontario, is a signatory to the Advanced Cooling Challenge, an initiative of Clean Energy Ministerial where TORO WATT committed to introducing a 50% more energy efficient residential Air Conditioner. TORO WATT designed & developed the Room Air Conditioner based on Dual Path Technology using conventional refrigerants for the time being but reduced refrigerant charge by 50% for the given capacity. Mass production of these units requires minor changes to the current manufacturing processes. The outcome besides reducing the refrigerant emissions by 50%, will also reduce the carbon footprint of the air conditioner by 50% reducing strain on the already stressed ecosystem. This changeover will actually be an opportunity to achieve a leapfrog effect when integrated with natural refrigerants like hydrocarbons /ammonia in the residential air conditioning. This should happen as the next logical step and sooner.

Cool Phase Ventilation System - Phase Change Materials New Applications (Monodraught)

COOL-PHASE is an award winning natural cooling and low energy ventilation system that creates a comfortable, fresh and healthy indoor environment that can significantly reduce the running costs of buildings. The system uses the concept of a ‘Thermal Battery’ to capture and store heat and cooling energy. The Thermal Batteries use the latent heat property of a Phase Change Material (PCM) to store large amounts of energy. This PCM changes phase at room temperature and is charged and discharged by passing air through its thermal batteries releasing the stored energy when it is required. The COOL-PHASE system monitors indoor and outdoor temperatures, internal CO2 levels and humidity and automatically ventilates the space via the means of an intelligently controlled Air Handling Unit.
