ENERGY EFFICIENT REFRIGERATED ROOM WITH OPTIONALLY ASSOCIATED GEOTHERMAL EARTH LOOP SYSTEM

摘要

A walk-in refrigeration room system effective for providing and defining an interior chilled air space includes an outer wall layer, a framing layer defining a series of spaces having a depth of at least 6″ inside the outer wall layer, an outer layer of insulation that has been sprayed into the framing layer spaces, a middle wall layer, an inner foamboard insulation layer, a vapor barrier layer, an optional inner wall layer, a door to permit walk-in access to the interior chilled air space, and one or more functional openings to permit electrical connections and/or chilled air to enter or exit the chilled air space. The inner wall layer forms an air-tight envelope when any doors or windows in the inner wall layer are closed. The outer insulation layer and the inner insulation layer overlap in a manner that does not contain any insulation gaps or thermal bridges.

1. A walk-in refrigeration room system effective for providing and defining an interior chilled air space, the system comprising:
a) an outer wall layer; b) a framing layer defining a series of spaces having a depth of at least 6″ inside the outer wall layer; c) an outer insulation layer comprising insulation that has been sprayed into the framing layer spaces; d) a middle wall layer preferably comprising plywood sheets; e) an inner insulation layer comprising a foamboard insulation material; f) an optional vapor barrier layer comprising fiberglass reinforced vinyl sheets (FRV) or fiberglass-reinforced plastic sheets (FRP); and g) an optional inner wall layer. h) a door sized to permit walk-in access to the interior chilled air space; i) one or more functional openings to permit electrical connections and/or chilled air to enter or exit the chilled air space; wherein the inner wall layer forms an air-tight envelope when any doors or windows in the inner wall layer are closed; and wherein the outer insulation layer and the inner insulation layer overlap in a manner that does not contain any insulation gaps or thermal bridges.
