What is Solar Absorption Cooling?

Solar Absorption Cooling is an increasingly popular choice for commercial buildings and facilities seeking environmentally-friendly solutions.  Solar Absorption Cooling systems provide the HVAC requirements for commercial buildings in a turn-key solar heating and cooling solution with "absorption chillers." Absorption chillers "energy" come from solar thermal systems - either from solar thermal collectors or evacuated tube collectors.

 

Absorption chillers use heat instead of mechanical energy to provide cooling. A thermal compressor consists of an absorber, a generator, a pump, and a throttling device, and replaces the mechanical vapor compressor.

 

In the chiller, refrigerant vapor from the evaporator is absorbed by a solution mixture in the absorber. This solution is then pumped to the generator. There the refrigerant re-vaporizes using a waste steam heat source. The refrigerant-depleted solution then returns to the absorber via a throttling device. The two most common refrigerant/ absorbent mixtures used in absorption chillers are water/lithium bromide and ammonia/water.

The two most common refrigerant/ absorbent mixtures used in absorption chillers are water/lithium bromide and ammonia/water.

 

Compared with mechanical chillers, absorption chillers have a low coefficient of performance (COP = chiller load/heat input). However, absorption chillers can substantially reduce operating costs because they are powered by low-grade waste heat. Vapor compression chillers, by contrast, must be motor- or engine-driven.

 

Low-pressure, steam-driven absorption chillers are available in capacities ranging from 100 to 1,500 tons. Absorption chillers come in two commercially available designs: single-effect and double-effect. Single-effect machines provide a thermal COP of 0.7 and require about 18 pounds of 15-pound-per-square-inch-gauge (psig) steam per ton-hour of cooling.

 

Double-effect machines are about 40% more efficient, but require a higher grade of thermal input, using about 10 pounds of 100- to 150-psig steam per ton-hour.

 

A single-effect absorption machine means all condensing heat cools and condenses in the condenser. From there it is released to the cooling water. A double-effect machine adopts a higher heat efficiency of condensation and divides the generator into a high-temperature and a low-temperature generator.

 


What is "Net Zero Energy?"

Net Zero Energy - when applied to a home or commercial building, simply means that they generate as much power and energy as they consume, when measured on an annual basis.

The U.S. Army now has a Net Zero Energy initiative to help reduce/eliminate America's use of foreign oil  - particularly oil from muslim/middle-east countries - which saves the lives of our brave soldiers in the military.

Clean Power Generation Solutions


CHP Systems (Cogeneration and Trigeneration) Plants
Have Very High Efficiencies, Low Fuel Costs & Low Emissions

The Effective Heat Rate is Approximately
4100 btu/kW & System Efficiency is 92% Plant.

The CHP System below is Rated at 900 kW and Features:
(2) Natural Gas Engines @ 450 kW each on one Skid with Optional
Selective Catalytic Reduction
system that removes Nitrogen Oxides to "non-detect."


CHP Systems (available in either cogeneration or trigeneration) may be the best solution for your company's economic and environmental sustainability as we "upgrade" natural gas to clean power with our clean power generation solutions.

Emissions Abatement solutions reduce Nitrogen Oxides to "non-detect" which means our CHP Systems can be installed and operated in most EPA non-attainment regions!
