The gas air conditioning system offers a multitude of benefits, including economic efficiency, energy conservation, space conservation, and easy management. And the system is clean because it uses city gas. This system is increasingly being installed for a wide range of purposes from individual buildings such as office buildings, shopping centers, schools and hospitals to district heating and cooling systems.
　Recently, an absorption type which effectively utilizes the waste heat from the cogeneration system and solar power, and GHP which can generate electricity have been developed and are expected to be deployed further.
　Increased promotion of gas cooling systems are expected from a national energy policy perspective, since these systems help mitigate the peak electricity demand in summer.
