Chiller is a water-cooling equipment, water chiller is capable of providing a constant temperature, constant current, constant cooling water equipment.
Xianxiang machine within a certain amount of water injected into the tank through the water-cooled chiller cooling system, and then by the low-temperature cooling water pump water into the device to be cooled, chilled water chillers heat away after the return flow temperature water tank, to achieve a cooling effect.
Use of air conditioning in the air conditioning system editor, chilled water is usually assigned to the heat exchanger or cooling coil air handling units, or other types of terminal equipment to redistribute in their respective space (S air), then back to the cooling water cooling It was cooled. These cooling coils transfer of sensible and latent heat from the air to the chilled water, therefore, usually dehumidification cooling air flow. A typical air conditioning unit rated app of 15-1500 tons (180,000 18,000,000 Btu / h or 53 to 5,300 kW) cooling capacity. Chilled water temperature ranges from 35-45 degrees Fahrenheit, or 1.5 to 7 degrees Celsius, depending on the application requirements.
Circulatory system
When the chiller refrigerant circulatory system evaporator liquid refrigerant absorbs heat and the water began to evaporate, a certain temperature is formed between the ultimate difference between refrigerant and water, the liquid refrigerant has completely evaporated into gas after the compressor suction and compressed gaseous refrigerant absorbs heat through the condenser, condensed into a liquid, after the adoption of thermal expansion valve throttling into low-pressure refrigerant into the evaporator, the refrigerant to complete the process of reincarnation.
When the chiller molded article due to variety of raw materials, different areas of the molded article size and shape, the clamping force required is different, please transfer mode when the minimum clamping force actually needed adjustment. In this way, it can save power consumption and significantly extend the life of the machine.
Industrial chillers use when the machine will pay attention to the safety of the operation, each operation is started Check machine safety devices, safety and security gate rams reliability. Machine running the process, remember not to put his hand into which clamping mechanism. When taking products, be sure to open the security door, after confirming the safety of personnel and no foreign body within the mold in order to close the safe door. In addition, the operation can not be inserted into the hand between the nozzle and the mold gate. When mold repair, turn off the pump motor.
Screw chiller with high efficiency, good performance, low noise, vibration, high energy efficiency, reliability, long life and other advantages. According to customer needs and cold tonnage, the use of single or multi-machine combination. Compressor Keyi load changes, automatically alternately move forward, operating hours of each compressor is balanced, greatly extending the life of the chiller. 1. When using the injection molding machine industry dedicated chiller models selected for the size of the injection molding machine mold cooling that is required of chiller 25HP. When used as a cooling other devices, depending on the specific flow of cooling water to be. Holding tank and pump selection, sometimes with the chiller 2. According to the actual situation of the factory, open chiller, when an external pump, the pump power requirements with the same type of box chiller requirements are the same. 3. chiller backwater temperature, preferably not higher than 40 degrees, the higher the return water temperature, the greater the damage to the compressor.
