The current global population of 7.8 billion is projected to grow to 9 billion by 2050, with 80% living in urban areas. Crop yields of traditional farming are inadequate and compounded by climate change, there is a push towards vertical farms to meet increasing food demand. Vertical farms have sprung up in industrial buildings, warehouses and shipping containers. Vertical farms use small urban spaces, 95% less water, less soil or no soil, no pesticides, and less fertilizer than traditional farms and achieve much higher crop yield than traditional farming on agricultural land. The vertical farming market is forecasted to hit US$13 billion by 2024, of which 70% will be indoor farming in urban spaces.
Maximising crop yields of indoor farms require careful monitoring and control of temperature, humidity, lighting, water supply, nutrient content and CO2 and these parameters vary for different type of crops.
Unlike conventional vapour compression air conditioner where temperature and humidity are controlled in a single process, NUScool’s patented technologies use two separate processes to achieve the desired humidity and temperature, and thus enabled more precise control of the humidity and temperature, and consume less energy. If installation of an in-situ power generator is allowed, the CO2 can be captured and channelled to the indoor farm to aid photosynthesis.
