Comparing energy usage
Superior Energy Efficiency
Our HVAC system consumes up to 71% less energy compared to compressor-based refrigerant systems over 40RT. Low power consumption is achieved by using waste and renewable thermal energy rather than electrical energy as the primary power.
Comparing energy Sources
Utilizes Low Grade Waste Heat and Renewable Heat sources
Heating is primarily sourced from low grade waste heat between 60 to 95 °C and renewable heat sources, enabling passive heating, supplemented by a boiler.
During summer operation, chilled water is produced by an adsorption chiller, which is powered by the same low-grade heat.
Superior equipment
Adsorption Chiller
In this HVAC system, chilled water is produced by an adsorption chiller. These chillers use very little electricity and are instead powered by low grade thermal energy in the form of water at 60-95°C. These chillers are reliable, rugged, low maintenance, and have a long service life.
Freezing Climate Design
Designed for Freezing Climates
In the winter the adsorption chiller is bypassed and chilled water is provided by cooling tower. Passive cooling is achieved, reducing/eliminating thermal energy requirements for cooling and dehumidification during the winter.Allowing closed loop HVAC operations year-round.
Self Maintenance
Self Maintainable
As well as requiring much less maintenance compared to traditional chillers, adsorption chillers do not use refrigerants making maintenance simpler and safer.
At under 50 lbs, the modular heating and cooling in room HVAC coils can be swapped during operation by a single worker and are pressure washable allowing for self maintenance in locations with no or low coverage by HVAC technicians.
Sustainability
Sustainable Design
The use of hydronics and a compressor-less cooling system eliminates the use of high global warming potential (GWP) refrigerants from the HVAC system.
Greatly reduced electricity consumption and the reuse of waste heat as thermal energy greatly reduce the system’s environmental impact compared to traditional HVAC systems.
Pest Reduction
Allows for Closed Loop HVAC
HVAC system is economical and effective allowing for heating, cooling, and dehumidification. This allows for greenhouses to not rely on open ventilation for cooling and dehumidification. Closed loop HVAC reduces pest infiltration and exfiltration and prevents disease for the individual farm and the broader greenhouse industry.
