Air-cooled module for an air-cooled refrigeration cycle apparatus, comprising a desuperheater and condenser heat exchanger configured for being fluidly connected to compressor means of the air-cooled refrigeration cycle apparatus and a subcooler configured for being fluidly connected to expansion means of the air-cooled refrigeration cycle apparatus, both the desuperheater and condenser heat exchanger and the subcooler being configured to allow the passage of a refrigerant fluid inside themselves for cooling the refrigerant fluid thanks to an air flow directed to pass through these latter, the subcooler being fluidically in series downstream and physically separated with respect to the desuperheater and condenser heat exchanger, these latter elements being positioned relatively so the air flow passes before in the subcooler and then in the desuperheater and condenser heat exchanger.

Multi-unit cooling systems and structures thereof for residential, commercial, or other buildings. In one embodiment, a support duct system comprises a support duct frame including a longitudinal axis and at least one mounting bracket support, each of the at least one mounting bracket support being movable relative to the longitudinal axis of the support duct frame; and at least one mounting bracket coupled to a corresponding one of the at least one mounting bracket support, each of the at least one mounting bracket being removably couplable to a corresponding cooling unit. Each of the cooling units is independently rotatable relative to the longitudinal axis of the support duct frame.

Embodiments of the present disclosure provide an array of modularized circuits that work individually but collectively to provide a system that can manage an indoor environment. The system is designed in order to match the delivered load more closely to the required load then has been done in the past. The system is also designed in order to enhance and ease of serviceability of the individual circuits when needed.

A structure for a multi-story building comprises a first passageway constructed internally within a building being configured with a mount for a ducted condenser unit (DCU) of a split type, unitary air conditioning system to achieve a desired level of condenser based heat dissipation and with a plurality of penetrations to accommodate a conduit through which refrigerant circulates between inside and outside units of the air conditioning system; and a second passageway constructed internally within the building for receiving air discharged from the DCU the second passageway terminating at an opening of the building through which the discharged air is exhausted to the atmosphere. The passageways have walls that are essentially closed, with the exception of the wall that is formed with an opening through which the discharged air flows. One or both of the first and second passageways upwardly extends across at least two stories of the building.

According to certain embodiments, a thermostat is configured for use in a climate control system. The thermostat is operable to use two-way communication for communicating operational information between the thermostat and at least one rooftop unit (RTU) within the climate control system. For example, the two-way communication comprises sending first operational information to the RTU and receiving second operational information from the RTU. The operational information comprising one or more climate control commands, setpoints, configuration information, diagnostics, and/or sensor data. The thermostat is further operable to operate the climate control system based on the operational information communicated between the thermostat and the RTU.
