Abstract

Systems, methods, and apparatuses are provided for preventing condensation in refrigerated display cases. A display case (100) can be provided with one or more heater circuits (105,110) and one or more sensors (120) communicably coupled thereto. The sensor (120) can sense ambient humidity levels, ambient temperature levels, and surface temperature levels. In certain embodiments, dewpoint temperatures may be calculated based on the ambient humidity and temperature levels provided by the sensor (120). The sensed ambient humidity level, temperature level, surface temperature, or calculated dewpoint can be compared to preset trigger levels and at least one of the heater circuits (105,110) can be activated if the preset trigger level is violated. Activation of the heater circuit (105,110) can be for a predetermined amount or percentage of time or at a predetermined voltage level based on the sensed or calculated level or the amount the sensed or calculated level is over the preset trigger level.

Abstract

The present application provides a compressor manifold assembly (110, 400). The compressor manifold assembly (110) may include a suction manifold (130) with a number of suction manifold modules (140), a discharge manifold (240) with a number of discharge manifold modules (250), and a number of compressors (120) positioned on the suction manifold (130) and the discharge manifold (240). Alternatively, the compressor manifold assembly (400) may include a unitary manifold (410) including a suction conduit (450) and a discharge conduit (480) extending therethrough, and a number of compressors (120) positioned on the manifold (410).

Abstract

The present application provides an attachment system (100) for mounting a microchannel coil (10) to a support structure (80). The attachment system (100) includes a bracket (110) fixedly attached to the microchannel coil (10), a grommet (160) positioned about the bracket (110), and a fastener (200) extending through the grommet (160), the bracket (110), and the support structure (80) so as to attach the microchannel coil (10) thereto. The grommet (160) includes a vibrationally isolating material so as to isolate the microchannel coil (10) from the support structure (80).
