Abstract
Official abstract text for this publication.
A method for freeze protection for a temperature control system, and a temperature control system for controlling the temperature of a temperature-controlled space at a set point temperature. The method includes monitoring a discharge air temperature, monitoring a return air temperature, setting a target temperature to equal the set point temperature, controlling the return air temperature at the target temperature, and adjusting the target temperature based on the return air temperature when the discharge air temperature drops to one of at or below freezing.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for freeze protection for a temperature control system, the temperature control system for controlling the temperature of a temperature-controlled space at a user-selected set point temperature, the method comprising: monitoring a discharge air temperature; monitoring a return air temperature; with a controller, setting a return air target temperature to equal the user-selected set point temperature; controlling the return air temperature to b…
