Abstract
The cooling system supplements the cooling of a walk-in cooler by injecting outside cold air via an outside air intake. The system includes air intake ductwork adapted to vent cold outside air into the walk-in cooler and air return ductwork that circulates the air to provide cross-flow of the injected cold air. Inline fans are connected to an interior thermostat. Motorized dampers are connected to a thermostat with an exterior temperature probe. The system thermostats are set slightly cooler than any pre-existing thermostat operating the pre-existing refrigeration system.
Claims4
A cooling system, comprising:
- a top outside duct adapted for mounting external to a structure housing a cooler room;
- an outside ambient air temperature probe mounted on the top outside duct;
- an air intake B-vent connected to the top outside duct, the B-vent being adapted for extending through a roof of the structure housing the cooler room;
- an outside air thermostat mounted on the air intake B-vent, the outside air thermostat being connected to the outside ambient air temperature probe;
- an air intake B-vent slider connected to the air intake B-vent;
- an inline air intake fan connected to the B-vent slider;
- a motorized damper connected to the inline air intake fan, operation of the motorized damper being controlled by the outside air thermostat so that the damper opens when ambient outdoor temperature falls below a temperature set on the outside air thermostat and the damper closes when ambient outdoor temperature rises above the temperature set on the outside air thermostat;
- a transition duct connected to the damper, the transition duct being adapted for extending through a ceiling of the cooling room;
- a diffuser connected to the transition duct for diffusing airflow from the transition duct into the cooler room;
- air return ductwork adapted for extending through the ceiling of the cooling room;
- an air return grille adapted for being disposed in the ceiling of the cooling room, the grille being connected to the air return ductwork;
- an air return motorized damper connected to the return ductwork;
- an air return inline fan connected to the air return damper;
- an air return B-vent slider connected to the air return fan;
- an air return B-vent extending upward from the air return B-vent slider, the air return B-vent being adapted for extending through the roof of the cooling room housing structure;
- an inside air thermostat adapted for mounting in the cooler room, the inside air thermostat being connected to the inline air intake fan and the inline air return fan, the inside air thermostat having a temperature setting controlling operation of the inline air intake fan and the inline air return fan when the air intake and air return dampers are open;
- and
- a cap disposed atop the air return B-vent.
