Abstract: A power emulating module within a powering system for a direct current air conditioner that utilizes solar cells array as a power source. The power emulating module enables to both convert the source signal from the solar cells array into the required voltage levels for the direct current motor of the air conditioner and further generate an alternating current control signal required for the motor control modules. In embodiments, the power emulating module is arranged to be retrofitted into an existing direct current air conditioner exhibiting a rectifying bridge, a motor power module and a motor control module, wherein the air conditioner is operable with an alternating current source. This is achieved by bypassing the rectifying bridge and routing the solar cells array via the power emulating module to the motor power module and further connecting power emulating module to the existing motor control module.

Abstract: Air cooling assembly (ACA) 100 uses AC section 300 that comprises AC compressor unit 30, AC channel 32, AC condensation unit 33 and AC evaporator 31. ACA 100 integrates the AC section 300 with an IWC section 200 that comprises IWC compressor unit 20 that is used to cool a refrigerant that runs through IWC compressor unit channel 24, where IWC compressor unit channel 24 cools water that further evaporate through IWC evaporator 21 and IWC condensation unit 23. Cross-flow-fan (CFF) 40 draws the cooled air that results from both IWC section 200 and AC section 300 and disperses the cooled air into an indoors environment. AC condensation unit 33 and IWC condensation unit 23 provide a strata manifold of pieces for the accumulation of condensed water.

Abstract: A poultry coop comprises a plurality of feeding troughs, a winding drum and cable for each trough, a common drive for all the winding drums, and a clutch for each of the winding drums including a manually movable operator for selectively coupling and decoupling its respective winding drum to the drive in order to lift or lower its respective feeding trough.
