What You Need to Know about cooling
There are two types of cooling that should be considered if you want to make your home more appropriate: comfort cooling and process cooling. Comfort cooling is the same type of cooling system that can be found in residential houses and office buildings. It is made to cool spaces mainly to create comfortable temperatures for occupants.
The process of cooling is generally less familiar to the typical consumer. Although, it is no less common than comfort cooling. Process cooling is designed for heat processing and removing large amounts of heat from a space, which is typically done with a chiller system. Chiller systems are commonly found in data centers, plastic injection molding and airports and hospitals - huge buildings requiring a lot of heat to be removed.
Chiller systems are originally used for high heat and large commercial environments. The main reason is that they provide a number of benefits over process cooling under such circumstances:
- N+1 excess is much more cost useful with a chiller system. In order to provide full system redundancy, with comfort cooling systems, other cooling unit is required for each room. With chiller systems, only one additional chiller unit is needed for the entire system for providing full system redundancy. This shortening in equipment needs results in system redundancy being much more cost active with a chiller system.
- Distinctive to indoor gardening, chiller systems are more cost effective when designed to be used on a “flipped” light schedule than comfort cooling.Among comfort cooling, the number of compressors remains the same, equally if only half of the available lights will be turned on at a single time. This is because of the individual compressors being tied to individual rooms. With chiller systems, it is possible to reduce the number of compressors needed by half when running on a “flipped” light schedule. Considering that the compressors are tied to the overall system, and not individual rooms, the amount of equipment needed can be based on the peak load of the system, noticeably than the number of rooms.
- Free cooling in the winter. With chiller systems, it is possible to add dry coolers to the system in order to cool water during the winter beyond running the compressors. This chilled water can then be used to cool the interior of the building without ever coming into direct contact with the air in the room. Willingly, with common cooling systems, in order to achieve free cooling in the winter, outside air must be brought into the grow room. This may cause a huge amount of problems, including the introduction of pathogens, reduction in CO2 levels and humidity spikes.
- Chiller systems do not require ducting, rather using plumbing. Ducting is expensive and creates an ideal breeding ground for mold and other pathogens if not cleaned frequently. Instead, chiller systems utilize plumbing to move liquid throughout the facility, allowing for sealed rooms and a cleaner form of cooling rooms.
Know your options when selecting HVAC for a garden environment, and consider these factors before making your final selection. With monthly cooling costs amounting to as much as 46% of electricity usage, the system you choose will have a large impact on your company’s bottom line.
