DSM enabling of electro mechanically controlled refrigeration systems
First Claim
1. A system for reducing peak power consumption by a refrigeration system, comprising;
- a first electromechanical cold control calibrated to a first temperature setpoint;
a second electromechanical cold control calibrated to a second temperature setpoint, said first and second cold controls each comprising a setpoint selector member, said setpoint selector members being operatively linked such that adjustment of one results in a corresponding adjustment of the other;
a demand side management (DSM) module responsive to demand state signals from an associated utility indicative of at least a peak demand and an off peak demand state; and
a DSM switching device responsive to said DSM module and operative to selectively render one or the other of said cold controls effectively operative to control a cooling system depending upon the demand state signals.

Abstract
A system for reducing the peak power consumption by a refrigeration system is provided. The system comprises a first electromechanical cold control calibrated to a first temperature setpoint, a second electromechanical cold control calibrated to a second temperature setpoint, said first and second cold controls each having a setpoint selector member operatively linked such that adjustment of one results in a corresponding adjustment of the other, a DSM module responsive to demand state signals from an associated utility indicative of at least a peak demand and an off peak demand state, and a DSM switching device responsive to the DSM module and operative to selectively render one or the other of the cold controls effectively operative to control the cooling system depending upon the demand state signal.

8. A method for reducing peak power consumption in an electromechanically controlled refrigerator comprising at least one compartment, said method comprising:
-
mechanically linking a first cold control comprising a first adjustable switch to a second cold control comprising a second adjustable switch; calibrating the first cold control to a first temperature setpoint and the second cold control to a second temperature setpoint, wherein said second temperature setpoint is higher than said first temperature setpoint; and opening and closing a demand side management (DSM) switching device in response to a signal received from an associated DSM module indicative of at least a peak demand state and an off peak demand state of an associated utility, wherein opening said DSM switching device shifts control from said first cold control to said second cold control, causing the temperature to be controlled to a higher setpoint temperature. - View Dependent Claims (9, 10, 11, 12)
