Air-cooled module for an air-cooled refrigeration cycle apparatus, comprising a desuperheater and condenser heat exchanger configured for being fluidly connected to a compressor of the air-cooled refrigeration cycle apparatus and a subcooler configured for being fluidly connected to an expansion member 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.

A solid-state cooling module includes a plurality of housing portions. Each of the housing portions houses a solid refrigerant substance. The solid-state cooling module is configured to heat or cool a heat medium flowing through insides of the plurality of housing portions. At least some of the plurality of housing portions are connected to each other in series with respect to a flow of the heat medium.

A decentralized condenser evaporator system includes (i) a condenser system positioned to receive a gaseous refrigerant from a centralized compressor system and configured to condense the gaseous refrigerant into a liquid refrigerant, (ii) a controlled pressure receiver positioned to receive and store the liquid refrigerant, (iii) an evaporator system including a conduit, an expansion valve, and a fan, and (iv) a controller. The conduit is positioned to receive the liquid refrigerant from the controlled pressure receiver. The expansion device is positioned between the controlled pressure receiver and the conduit, and configured to facilitate modulating an amount of the liquid refrigerant that flows into the conduit from the controlled pressure receiver. The fan is positioned to facilitate providing a cooling operation to an area associated with the evaporator system through evaporation of the liquid refrigerant flowing through the conduit. The controller is configured to control a stage of the condenser system and/or the evaporator system to maintain a desired level of the liquid refrigerant within the controlled pressure receiver and facilitate maintaining a system condensing pressure of the refrigeration system at a target system condensing pressure.

A modular heating and cooling unit comprising an independent set of headers for each of the heating and cooling loads and the source. A bank of these modular units provides a system that is capable of incremental simultaneous heating and cooling and redundancy. Valves in the internal piping of the unit eliminate the need for valves in the headers between units. This substantially reduces the overall footprint of the unit. Because of the parallel flow between the heat exchangers and the heating and cooling load, the modules can be operated in cooling mode and heating mode in any order.
