Abstract
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.
