This air-to-air heat exchanger provides a cool and comfortable indoor environment in warm and humid regions, whilst being very energy-efficient.

Generating good indoor air quality is often an energy-intensive and costly process, particularly in humid and warm climates. Conventional air-conditioning systems remove heat and moisture simultaneously, usually by cooling air to its dew point to remove moisture, before reheating it to a comfortable temperature. In contrast, Toro Cooling Systems’ dual path technology removes the need for excessive cooling and subsequent reheating of the air. Instead, the Toro Cooling System lowers the air temperature directly to the desired level and the moisture is removed separately. This eliminates energy-intensive components of the conventional cooling process, and it also requires less environmentally harmful refrigerant gases.

It is estimated that heating, ventilation and air-conditioning systems account for 31% of the electricity used by commercial buildings in India, where Toro’s solution is deployed. Conventional cooling systems require large amount of refrigerants, which are typically gases with high global warming potential. The technology used in Toro’s cooling system achieves annual electricity savings of up to 50% over conventional air-conditioning systems, and requires half the refrigerants, according to the company.
