AMMONIA ABSORPTION TYPE WATER CHILLING/HEATING DEVICE

摘要

An ammonia absorption type water chilling/heating device comprising a generator (22) for generating high pressure ammonia gas (21) from an aqueous ammonia solution (11) by a heat source, a rectifier (28) for gas-liquid separation to provide the ammonia gas (21) and a dilute ammonia solution (9), a condenser (23) for condensing the ammonia gas (21) after separation, an evaporator (24) utilizing the cooling action produced when an ammonia solution (94) after condensation is vaporized, and an absorber (25) for causing the aqueous ammonia solution to absorb the ammonia gas (21) after vaporization, these parts being successively arranged from top so that the dilute ammonia solution (9) may move by gravity. Such arrangement allows omission of a rectifying tower and connection piping, and reduces the size of the evaporator and absorber, thus making it possible to further reduce the size of the entire device and to cope with a variety of heat sources.
