Sound level control in an HVAC system
First Claim
1. A method of controlling a refrigeration unit for a heating, ventilation, and air conditioning (HVAC) system, comprising:
- determining, by a controller, a cooling requirement of a conditioned space;
determining, by the controller, a sound level operating range for the refrigeration unit; and
applying a cooling setting based on the cooling requirement and the sound level operating range, wherein the sound level operating range constrains the cooling setting such that when the cooling setting includes one or more settings outside the sound level operating range, the cooling setting is modified to be within the sound level operating range.

Abstract
A system and method for controlling a sound level in a heating, ventilation, and air conditioning (HVAC) system are disclosed. The system includes a refrigeration unit including a compressor, a condenser fan, a controller, and a sound controller. The sound controller is configured to maintain a sound level of the refrigeration unit within a sound level operating range. A method of controlling a refrigeration unit for a heating, ventilation, and air conditioning (HVAC) system is described. The method includes determining, by a controller, a cooling requirement of a conditioned space. The controller also determines a sound level operating range for the refrigeration unit. The method further includes the controller applying a cooling setting based on the cooling requirement and the sound level operating range.
