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 device, and then back to the oil tank. The controller adjusts the temperature of the heat fluid, thereby controlling the temperature of the temperature control device, based on the temperature of the hot fluid measured by the temperature sensor or the internal temperature of the temperature control device. Generally, water-based temperature control ranges are lower, while oil-based ranges are higher. The working temperature for water-based systems is 90°C, for pressurized water systems is 160°C to 180°C, and oil-based systems are used for temperatures ≥150°C, with a high working temperature of up to 350°C.

All-in-one refrigeration and heating machines can both heat and cool, allowing for quick switching to accelerate production and reduce energy consumption, enhancing product molding efficiency, and reducing defects and the production of defective products. Equipped with a computer touch control and automatic calculation, multi-point temperature control units can be customized. They can automatically control the temperature, quickly reach the set temperature, and display both set and actual values. Isolated electrical control cabinets extend the lifespan of electrical appliances, pipeline explosion-proof devices, built-in safety protection with low noise, high-temperature resistance, corrosion and rust prevention, special heating design, energy-saving, durable, and suitable for various temperature control environments. All-in-one ice and heat machines, all-in-one cold and hot machines, and all-in-one ice and heat mold temperature machines have fast heating and cooling speeds, uniform and stable temperatures, and energy-saving features.
