Cooling & Dehumidification
One of the most interesting elements of our system is our unique cooling/dehumidification unit. Our dehumidification unit with a pre-cooler reduces the load of the grow room by 40% and eliminates reheat requirements. When working with a chiller with an economizer it can make full use of “free” cooling in the winter.
Our dehumidification system is designed to capture the wasted heat from our liquid-cooled LED lights and use it for dehumidification and reheating purposes– reducing the cooling load. Our central facility control system optimizes operation conditions to maximize system efficiency.
- Working with a chiller with an onboard economizer provides free cooling in winter
- Designed to work with wide-ranging outdoor temperatures, while maximizing efficiency
- Both cost-effective and easily serviced
- Fully integrated with GSTS facility control system
Our engineering expertise in the HVAC technology field provides the most efficient and cost-effective design available.
Our dehumidification is simple in design yet extremely powerful in function.
What is an air-to-air heat exchanger?
- The air-to-air heat exchanger provides two separate air paths; which do not mix with one another, allowing for a thermal transfer of energy only from one air path to the other.
How GSTS cooling/dehumidification system works
Our innovative Dehumidification technology reduces up to 80% energy consumption in comparison to a traditional system
Our unique air-to-air heat exchanger design pre-cools the intake air from the grow environment using the cold air from the cooling coil while the cold air is reheated in the process to the level acceptable to the grow environment. This reduces cooling load by 40%. On the other hand, it essentially eliminates the reheat requirement, saving a lot of electric power or natural gas (or propane) consumption. The combined saving of cooling energy and reheating reduces up to 80% energy consumption.
Case Study Example
Hot humid air enters the dehumidification unit and flows into the Air-to-Air heat exchanger.
This humid, warm air, is cooled while it travels through the exchanger.
The air travels to the bottom of the dehumidification unit onto a liquid to air heat exchanger where condensation and dehumidification process occurs.
The deep-cooled air rises back up into the Air-to-Air heat exchanger
The deep-cooled air re-enters the air-to-air exchanger and is introduced* to the incoming warm air (which it cools) while being heated itself.
If the system requires higher discharge temperature the dehumidification system can use the wasted-heat from the liquid cooled LED to provide the extra thermal energy necessary to reheat.
