Air conditioning apparatus is disclosed. The apparatus includes, referring to FIG. 28 of the drawings, a number of air outlets 636, a dehumidifier 630, a constant pressure blower 833 in the dehumidifier 630 a duct 653 for circulating dehumidified air to the outlets 636, dampers 655 for controlling the rate at which dehumidified air circulated to the outlets 636 is delivered to a space to be conditioned, and panels 637 positioned in heat transfer relationship with space to be conditioned by the apparatus. The constant pressure blower controls the rate at which dehumidified air is delivered to the air outlets 636 so that dehumidified air is available at the rate required from time to time by each of the air outlets 636. Each of the air outlets 636 is operable to deliver air circulated thereto to a space to be conditioned. The dehumidifier 630 cools the air it conditions to a temperature sufficiently low that its moisture content and temperature are such that the dehumidified air is incapable, at the rate at which it is required for humidity control, of maintaining the desired space temperature at the maximum design cooling load.

Air conditioning apparatus is disclosed. The apparatus includes a plurality of air outlets, refrigeration apparatus operable to make ice by pumping heat from water to a heat sink and to store the ice, a coil for dehumidifying outside air or a mixture of outside air and return air, means for causing air to be dehumidified to flow in heat transfer relationship with the coil, means for circulating dehumidified air to the air outlets, means operable to control the moisture content and temperature of the dehumidified air, means operable to control the rates at which dehumidified air is delivered by the air outlets to the spaces they serve to ones not less than the predetermined minimum rate, and means for controlling the temperature of the air delivered to the air outlets to maintain the temperature of the spaces within control limits. Each of the air outlets is operable to deliver air to a space to be conditioned. The apparatus also includes means for circulating a low temperature heat transfer fluid through the coil, the circulating means including means for transferring heat from the heat transfer fluid to ice made and stored by the means operable to make and store ice.

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.

Air conditioning apparatus for a building having an electrical grid operatively connected to receive electricity from a utility is disclosed. The apparatus includes compression refrigeration apparatus with an electric motor connected to drive a compressor, absorption refrigeration apparatus, a cogenerator, an air handler, induction mixing units, a system for circulating air to be conditioned through the air handler and then to said induction mixing units, apparatus for transferring heat from air in the air handler to ice, a heat transfer system connecting the absorption refrigeration apparatus to pump heat to a heat sink from air in the induction mixing units or from air in the air handler, electric circuitry connecting the electric motor of the compression refrigeration apparatus to the building electrical grid for energization, and a heat transfer system for transferring heat generated by the cogenerator into energizing relationship with the absorption refrigeration apparatus. The compression refrigeration apparatus is operable to make ice, while the cogenerator is operable to generate electricity and heat. The cogenerator is connected to provide electricity to the electrical grid of the building, and the induction mixing units include a fan for causing a flow of recirculated air from a space to be conditioned, and, when conditioned air is circulated thereto, for delivering to the space a mixture of conditioned air and recirculated air.

An improved mixing box is disclosed. The mixing box comprises an inlet end, an outlet end, a substantially closed first passage to which primary air flows from a primary air inlet and then through induction means and to and from the outlet end. The induction means are positioned intermediate the inlet and outlet ends and are operable, when primary air flows through the passage, to induce a flow of air through a first opening for mixture with primary air and delivery therewith through the outlet end. The mixing box also comprises means for controlling the rate of flow of primary air and a fan operable to induce a flow of air through a second opening and to deliver such air through the outlet end of the box. The improvement includes a closed second passage formed in the mixing box for the flow of air from the second opening to the suction side of the fan and a control operable to energize the fan when the primary air flow is below a control rate and to de-energize the fan when the primary air flow is above the control rate. Additionally, the primary air inlet can open into the closed second passage which communicates directly with the first passage and therethrough with the induction means and the outlet end of the mixing box, while the fan discharges into the first passage and therethrough into the induction means, and through the outlet end of the box.
