Gas-fired chiller-heaters as a central plant alternative for small office buildings

In large projects where use of multiple chillers is feasible, gas absorption chiller-heaters are extensively applied. Large facilities typically have a substantial base cooling load. If the base load is greater than 30% of the minimum capacity of the smallest chiller, chiller-heaters alone can be used as the building central plant. However, in small office buildings, the use of other technologies is favored. The engineer can overcome these application problems by a variety of means.
