New Leaf Dynamic Technologies
New Leaf’s vision is to replace high-power-consuming heating, ventilation, and air-conditioning (HVAC) systems with sustainable, renewable energy-powered HVAC systems. To achieve this, the company has developed GreenAIR, a Liquid Desiccant Air-Conditioning System with a 10-50 ton-refrigeration (TR) cooling capacity that consumes only 10% of electricity from an equivalent grid-powered unit. New Leaf has also innovated GreenCHILL™; a Biomass-Powered Refrigeration Unit to safely store perishable produce using biomass and farm waste.
The company participated in a number of TechEmerge pilots which are described below. More data on the pilot experience is available from the report "TechEmerge Sustainable Cooling Innovation Program: Results and Lessons Learned."

Solutions
GreenAIR- Liquid Desiccant Air Conidtioner
GreenAIR is an environmentally sustainable central HVAC system for commercial buildings that is powered by heat. It uses a Liquid-desiccant dehumidification method to extract moisture from the air, controlling the humidity of the circulating air. An adiabatic desiccant is used for this process. Integrating the liquid-desiccant dehumidification module with an evaporative cooler extends the operational envelope to high humidity conditions.
Cold Storage Powered by Biomass/Farm Waste
GreenCHILL™ is a standalone biomass-powered refrigeration unit designed to integrate with any standard industrial grade cold room with storage capacities of 10 metric tons (MT), 15MT or 20MT.
It uses adsorption refrigeration technology-based system combined with a biomass boiler that provides hot water for driving the adsorption cycle. It operates with R717(ammonia) as a refrigerant, which has zero ozone depletion potential (ODP) and zero global warming potential (GWP). The average quantity of agricultural waste required per day is around 60 – 120 kilograms to maintain temperatures between 0°C and 25°C.
