The working principle of the refrigeration and heating unit: The pump drives the heat transfer medium (usually water or oil) from the oil tank equipped with an internal heater to the temperature control unit, and then back to the oil tank. The controller adjusts the temperature of the heat transfer medium based on the temperature of the hot fluid measured by the temperature sensor or the internal temperature of the temperature control unit, thereby regulating the temperature of the temperature control unit. Generally, water-based systems have a lower temperature control range, while oil-based systems have a higher temperature control range. The working temperature of water-based systems is 90°C, and that of pressurized water systems is 160°C to 180°C. Oil-based systems are used for operating temperatures of ≥150°C, with a high operating temperature of up to 350°C.
