Abstract
Apparatus for conditioning the air of a closed space and for removing heat from a refrigerated display case in the space is disclosed. The apparatus includes first refrigeration apparatus, second refrigeration apparatus, a chemical dehumidifier which uses a desiccant, a regenerator for the dehumidifier, a cogenerator for converting a fuel into heat and shaft work, means for transferring heat from the cogenerator to the regenerator to enable regeneration of the desiccant of the dehumidifier, means for transferring heat from the condenser of the first refrigeration apparatus to the heat absorbing section of the second refrigeration apparatus, and means for causing air to flow in dehumidifying relationship with the dehumidifier and then into the space. The apparatus is operable to maintain the temperature of the case below that of the closed space and to deliver dehumidified air to the space to maintain a humidity ratio in the closed space below about 50 grains of moisture per pound of dry air. The first refrigeration apparatus has a heat rejecting section, a compressor, and a heat absorbing section operatively associated to transfer heat from the refrigerated case, while the second refrigeration apparatus has a heat absorbing section, a heat rejecting section and a compressor. The cogenerator is connected in driving relationship with the compressor of the second refrigeration apparatus.
