A combined environmental and refrigeration system for use in a supermarket or the like includes a plurality of environmental and refrigeration modules and controllable air flow dampers to provide selected air flow modes to a conditioned space. Each module includes a hot deck compartment having a fan and the condenser portion of a refrigeration system to heat an air flow through the hot deck compartment, and a cold deck compartment having the evaporator portion of an air conditioning system to cool the air supplied to the conditioned space. At least a portion of the condenser in one of the hot deck compartments is provided to sub-cool the refrigeration system working fluid. The various fans, evaporators, condensers, and dampers are controlled by suitable control means to provide a conditioned space dehumidification mode, and a plurality of conditioned space cooling and heating modes. The system permits precise four season environmental control of the conditioned space while increasing the efficiency of the refrigeration system by reclaiming the heat rejected by the refrigeration cycle and sub-cooling the refrigeration system working fluid during the dehumidification and heating modes.

An environmental and refrigeration system for supplying conditioned air to a conditioned space comprising: a condenser connected to a refrigeration system for condensing a refrigeration system working fluid, said condenser having a main section and a sub-cooler section connected together in continuous series flow, the refrigeration system working fluid adapted to pass through said main section and then through said sub-cooler section; an evaporator connected to an air conditioning system for evaporating an air conditioning system working fluid; first air flow controlling means for selectively passing a flow of space air from a conditioned space over at least a portion of said main section and/or over said evaporator and for passing outside air from the environment over said sub-cooler; second air flow controlling means for selectively passing air from said condenser to said conditioned space or said environment; said first air flow controlling means configured, when said environmental and refrigeration system is in a heating mode, to pass space air over at least a portion of said main section to thereby heat the space air with heat reclaimed from said refrigeration system and to pass outside air over said sub-cooler section to sub-cool said refrigeration system working fluid; and said second air flow controlling means configured, when said environmental and refrigeration system is in the heating mode, to return the heated space air from said main section to the conditioned space, and to return the outside air from said sub-cooler to the environment.
