Abstract
An example control system for a temperature controlled environment operates by alternatively executing on-cycles during which the controller controls the compressor to operate in an on-state and off-cycles during which the controller controls the compressor to operate in an off-state. During the off-cycle the control system executes a defrost cycle. To reduce power consumption of the temperature controlled environment, the control system executes a particular defrost cycle during the off-cycle based upon a stored indication of defrost cycle type.
Claims20
A control system for a temperature controlled environment, the control system comprising:
- a controller operatively connected to:
- an evaporator configured to receive refrigerant that flows from an input of an evaporator coil to an output of the evaporator coil;
- a compressor configured to receive the refrigerant from the output of the evaporator coil and compress the received refrigerant;
- a condenser configured to receive refrigerant from the compressor, condense the refrigerant, and provide the refrigerant to the input of the evaporator coil;
- and
- at least one sensor configured to capture sensor data indicating a temperature associated with the evaporator coil;
- and
- one or more memory units communicatively coupled to the controller and storing (i) an indication of a defrost cycle type, and (ii) executable instructions that, when executed by the controller, cause the controller to alternatively:
- (a) execute an on-cycle during which the controller controls the compressor to operate in an on-state to cool the temperature controlled environment to a set point temperature;
- and
- (b) execute an off-cycle during which:
- (i) the controller controls the compressor to operate in an off-state, and
- (ii) the controller executes a defrost cycle based upon the stored indication of the defrost cycle type.
A method for operating a control system of a temperature controlled environment comprising (i) a controller operatively connected to (a) an evaporator configured to receive refrigerant that flows from an input of an evaporator coil to an output of the evaporator coil;
- (b) a compressor configured to receive the refrigerant from the output of the evaporator coil and compress the received refrigerant;
- a condenser configured to receive refrigerant from the compressor, condense the refrigerant, and provide the refrigerant to the input of the evaporator coil;
- and (c) at least one sensor configured to capture sensor data indicating a temperature associated with the evaporator coil;
- and (ii) one or more memory units communicatively coupled to the controller and storing an indication of a defrost cycle type, the method comprising:
- alternating, by the control system, between:
- (a) executing an on-cycle comprising:
- controlling, by the controller, the compressor to operate in an on-state to cool the temperature controlled environment to a set point temperature;
- and
- (b) executing an off-cycle comprising:
- (i) controlling, by the controller, the compressor to operate in an off-state, and
- (ii) executing, by the controller, a defrost cycle based upon the stored indication of the defrost cycle type.
