Commercial Air Conditioning

Commercial air-conditioning usually relies on the use of large chillers to distribute cooled water around a building. Cool technologies used in commercial air-conditioning usually involve ammonia for larger chillers and hydrocarbons and carbon dioxide for smaller chillers.

A combination of energy efficiency measures and natural refrigerants could reduce total global emissions from air-conditioning by 40%-60%.

Office building in Seattle, Washington, designed by Weber & Thompson, requires no air-conditioning. The building has green-tinted glass shades (or sunglasses) that sheild windows from heat, while still allowing light into the building. Heat reflective coating on the windows also reduces temperatures. The 40,000 square foot structure has a central courtyard, which allows cross breezes to enter all parts of the building, and allows more natural light into the building.

The system utilizes reclaimed heat from the refrigeration system to reactivate the desiccant system, thus allowing the normal air-conditioning equipment to run at a higher operating point. The system is expected to increase overall store energy efficiency by roughly 20%, and it is now being rolled out across the industry.

Ammonia is typically associated with larger cooling installations. However, York Company produces smaller ammonia chillers under the brand name ChillPAC. They use a single-piston compressor, plate heat exchanger, liquid separator, automatic oil return and electronic control in front panel. These have been applied in radio studios, computer centers, and offices. It would be technically possible to build ammonia chillers for domestic use. However, there would need to be economies of scale to make these commercially feasible. Partial list of Sabroe Johnson Controls ChillPAC installations:ChillPAC 106ER used in 2 office buildings in Switzerland, ChillPAC 116E used in 2 food factories in Malaysia, ChillPAC 112E used in a food factory in Korea, ChillPAC 112LR used in 4 data centers in Switzerland, ChillPAC 106S used in an office building in Switzerland, ChillPAC 108S used in 2 food factories in France, ChillPAC 116L used in a food factory in Italy, ChillPAC 116E used in a food factory in Turkey, ChillPAC 116LR used in a food factory in Thailand, ChillPAC 112LR used in 2 food factories in Switzerland, ChillPAC 116E used in 3 food factories in United Arab Emerites, ChillPAC 106LR used in 2 food factories in Dubai, ChillPAC 116ER used in 2 food factories in Dubai, ChillPAC 104L used in 2 R&D centers in France, ChillPAC 108E used in a food factory in Vietnam, ChillPAC 116ER used in a food factory in Switzerland, ChillPAC 108LR used in a food factory in Thailand.

At Roche’s Indianapolis facilities fluorocarbon chillers are in the process of being replaced with ammonia in the facility’s 16,000 m² chiller plant building. In Ireland, a similar replacement reduces Roche’s CO2 emission by 575 tons annually. In Germany, the company is using a mixture of ammonia, propane, and CO2.

The company estimates 3-5 years payback time on capital costs, depending on local irradiance conditions.

The Vicot solar ammonia-water air conditioning was a joint development between the Chinese company Vicot and Rocky Research of the United States. The system uses 8kg of ammonia in one 21kW unit. The modular assembly can connect up to 8 units under one control.The Vicot solar air conditioning system consists of three components, i.e. the solar collector, the air conditioner, and the thermal energy storage system. The solar trough collector is designed to be capable of reaching up to 300°C. A heat transer loop transports thermal energy to the absorption air conditioner. The absorption chilller converts the high temperature heat into building cooling and heating via a hydronic chilled water system. The system facilitates 24-hour solar power driven air conditioning for cooling, heating, and domestic hot water with built-in thermal energy storage. Thermal energy storage is provided via the phase change heat storage system and/or an ice storage system allowing continuous chiller and heater operation throughout the night and during cloudy days.The company estimates 3-5 years payback time on capital costs, depending on local irradiance conditions. The technology is applicable for domestic, commercial and industrial sectors.

Industrial Solar GmBH uses solar process heat (thermal energy) for commercial and industrial heating and cooling applications with a temperature range fo 130-400C and cooling capacities in the single digit and lower double digit Megawatt power range. With this system, they can substitute fossil fuels in commercial and industrial procsses to generate heat. Along with the heating aspect, by means of absorption chillers using NH3 and water as the refrigerant, their system can use thermal energy as means of a generator to convert heat to cold air, i.e. solar cooling. In 2006, the company installed their first solar cooling system with its Fresnel collector in Italy. Since then, other solar cooling systems have been installed in Germany, Spain, Tunisia and Abu Dhabi, as well as a system for a football stadium in Qatar providing the largest solar cooling system in the Middle East.
