In order to ensure the reliability and safety of the operation of the primary cooling speed hot mold temperature control system, the air-cooled chiller needs a number of auxiliary electrical equipments to serve, and a combination of several electrical components capable of realizing a certain control function is called Control loop or secondary loop. Kunshan mold temperature machine: the working principle of the freezer The freezer is a kind of cooling equipment. Before using it, you must understand the working principle of the freezer to better help you operate the freezer: its working principle is first to the inside of the machine. The water tank injects a certain amount of water, and the water is cooled by the refrigeration system, and then the low-temperature cooling water is sent to the equipment to be cooled by the water pump, and the chilled water takes the heat away and then the temperature rises and then flows back to the water tank to achieve the cooling effect.
Depending on the cooling medium and the cooling Screw-Type Condensing Units method, the condensers can be divided into three categories: water-cooled condensers, air-cooled condensers, and evaporative condensers. Reservoir: The reservoir is installed after the condenser and is in direct communication with the drain of the condenser. The air-cooled chiller is reliable because the refrigerant liquid of the condenser should flow unimpeded into the reservoir, so that the cooling area of the condenser can be fully utilized. On the other hand, when the heat load of the evaporator changes, the required amount of the refrigerant liquid also changes, and at that time, the reservoir functions to regulate and store the refrigerant.
Stable supply voltage and phase-to-phase voltage balance: The phase-to-phase voltage imbalance must not exceed 2% of the average phase-to-phase voltage. The capacity of the customer's power supply system should be large enough. When the capacity of the power supply system is insufficient, the voltage of the cold water industrial refrigeration unit will be drastically reduced, so that the industrial refrigeration unit cannot be started, and the motor will be damaged in severe cases. During the operation of this series of cold water industrial refrigeration units, the allowable voltage fluctuation does not exceed 5% of the rated voltage. The control box of the cold water industrial chiller is provided with a power inlet hole, and three fire lines are extracted from the wall power distribution equipment. A ground wire enters the electrical control box through the hole.
