Abstract
A temperature control system and method for regulating a liquid temperature in a recirculation system of a molding system includes determining an operating pressure of the liquid in the recirculation system, determining an operating temperature of the liquid in the recirculation system, receiving the operating pressure and the operating temperature, comparing the received operating temperature to a threshold temperature as a function of the operating pressure, and adjusting an output of a heat exchanger in the recirculation system when the operating temperature is beyond the threshold temperature.
Claims20
A temperature control system for molding equipment, the temperature control system comprising:
- a heat exchanger configured to change the temperature of a liquid in a recirculation system;
- a pressure sensor configured to determine an operating pressure of the liquid in the recirculation system and to output a pressure signal indicating the operating pressure of the liquid;
- a temperature sensor configured to determine an operating temperature of the liquid in the recirculation system and to output a temperature signal indicating the operating temperature of the liquid;
- and
- a controller configured to receive the pressure signal and the temperature signal, compare the operating temperature to a threshold temperature as a function of the operating pressure, and to send a signal to the heat exchanger to change a temperature of the liquid in the recirculation system when the operating temperature of the liquid is beyond the threshold temperature.
A method for regulating a liquid temperature in a recirculation system of a molding system, the method comprising:
- determining, by a pressure sensor, an operating pressure of the liquid in the recirculation system;
- determining, by a temperature sensor, an operating temperature of the liquid in the recirculation system;
- receiving, by a controller, the operating pressure and the operating temperature;
- comparing, by the controller, the received operating temperature to a threshold temperature as a function of the operating pressure;
- and
- adjusting, by the controller, an output of a heat exchanger in the recirculation system when the operating temperature is beyond the threshold temperature.
A non-transitory computer-readable medium including instructions that, when executed by a processor, are operable to:
- receive an operating pressure and an operating temperature of a liquid in a recirculation system of a molding system;
- compare the received operating temperature to a threshold temperature as function of the operating pressure;
- and
- adjust an output of a heat exchanger in the recirculation system when the operating temperature is beyond the threshold temperature.
