Solar Cooling

Plentiful sunshine gives an advantage to Spain for diversification of energy. As part of building a sustainable future, a 106kW Hot water Absorption Chiller with solar vacuum collectors and PV cells was installed for an eco-friendly office in Madrid, Spain.
During summer months, the solar vacuum collector provides 90℃ hot water for the Absorption Chiller and produces cooling for the office building using the underfloor cooling-heating system. During winter months, hot water from the solar vacuum collector is fed into the system for heating. A supplementary hot water boiler is always on standby for adverse weather condition.
This is truly a self-sustained solar cooling powered Eco-Building, which has used an Absorption Chiller with solar energy since 2003.
