A dual reclaim coil with a smart control application is provided that allows the refrigerant inlet to the HVAC unit switch between the two sides of the condenser for heat reclaim for refrigerants such as COwhich have a relatively low critical temperature compared to hydrofluorocarbon refrigerants. Heat reclaim after the exit of gas from the condenser utilizes the high temperature and pressure of the condenser/gas cooler outlet while a COrefrigerant system is operating above critical point. This occurs in hot ambient conditions, when the need for heating in the space is not as great as in the wintertime and the available heat at the condenser/gas cooler's outlet is sufficient to satisfy the heating load. When the COrefrigerant system is operating below the critical point, heat reclaim is carried out at the compressor discharge.

A refrigeration system includes a first portion having a primary loop and a secondary loop operably coupled by a first chiller, The primary loop circulates a refrigerant through the first chiller to provide cooling to a coolant in the secondary loop. The secondary loop has a supply portion and a return portion, the supply portion circulates the coolant to one or more temperature-controlled storage devices operating at a first temperature. A second portion has a primary loop and at least one secondary loop operably coupled by the second chiller. The primary loop circulates a refrigerant through the second chiller to provide cooling to coolant in the secondary loop. The secondary loop has a supply portion and a return portion, the supply portion circulates the coolant to one or more temperature-controlled storage devices operating at a second temperature. The return portion of the secondary loop of the first portion and the return portion of the secondary loop of the second portion share a common return header.

A modular refrigerated structure 10 includes a modular perimeter 12 which defines a refrigerated space 30, a plurality of display openings 24 about the perimeter 12 and at least one personnel access opening 32 for personnel ingress and egress to the refrigerated space 30. Shelves 40 are positioned at each display opening 24 for displaying products. A plurality of roof modules 56 are supported over the perimeter 12 and include a refrigeration module 67, an air passage 60 positioned above a centrally located storage area 38, an air distribution plenum 68 and air outlets 80 positioned adjacent the perimeter 12. The refrigeration module 67 includes refrigeration coils 74 and a fan 72, such that air is moved upwardly by fans 72 from the storage area 38 and into the refrigeration module 67, through the refrigeration coils 74, into the air distribution plenum 68 and laterally outwardly to the air outlets 80 about the perimeter 12 of the structure 10, and then downwardly between the display openings 24 and the shelves 40 for cooling products displayed on the shelves 40.
