The working principle of the mold temperature machine and chiller
Before understanding the working principle of the mold temperature machine, briefly introduce the components of the mold temperature machine: the mold temperature machine consists of a circuit control box, a heater, a heat exchanger (ie, a cooling system), a liquid level controller, a pressure limiter, a temperature sensor, Circulating pump and pipeline. Only when these parts cooperate with each other, the mold temperature machine can work normally and exert its function to the maximum.
The working principle of the mold temperature machine: the mold temperature machine pipeline is connected with the mold oil channel to form a circuit, and the heat-conducting oil is circulated under the action of the pump. The temperature sensor transmits data to the control system, automatically adjusts the heating / cooling action, and controls the temperature of the heat transfer oil.
The working principle of the chiller The refrigerant (ie, the refrigerant) absorbs the heat of the cooled object in the evaporator and vaporizes it into steam. The compressor continuously extracts the generated steam from the evaporator and compresses it. The high-pressure steam is sent to the condenser to release heat to the cooling medium (such as water, air, etc.) to condense into a high-pressure liquid. After the pressure is reduced by the throttling mechanism, it enters the evaporator and vaporizes again to absorb the heat of the object to be cooled. cycle.
During heating, the refrigerant changes the direction of refrigerant flow through the four-way valve. The direction of refrigerant flow is exactly the opposite of that during cooling. The refrigerant first passes through the evaporator, then returns to the condenser, and finally returns to the compressor.
