Air Chillers Cooling

　　Air chillers cooling are one of the chiller models. It cools the water at room temperature to a certain temperature through the compressor of the chiller to strengthen the cooling of the mold or machine. It is used as a stand-alone machine. The cooling device is a built-in fan. There are mainly three mutual Contact system refrigerant circulation system, water circulation system, electrical automatic control system.

　　Unit features

　　Air chillers cooling can be used in small systems, and most of the large units are water-cooled. In terms of long-term operation, the cooling efficiency of water-cooled units will decrease relatively, while air-cooled units will not.

　　Air chillers cooling adopts the air cooling method, which saves the cooling tower, cooling water pump and piping system that are necessary for the cooling water system, avoids condenser scaling and water pipe blockage caused by poor water quality, and saves water resources. Among the cold water air conditioning equipment products, it is the most economical and simple model for maintenance.

　　The one-time investment of air chillers cooling are slightly higher than that of water-cooled chillers, but the annual operating cost is lower than that of water-cooled chillers. or half the cost of the boiler.

　　The noise and volume of air chillers cooling are larger than that of water-cooled chiller, so it can only be installed outdoors. Water cooling units are mostly installed in underground rooms.

　　Features

　　1. The COP efficiency of the air-cooled chiller is lower, and the building area used is small

　　2. The COP of water-cooled chillers is generally relatively high, which is suitable for large buildings and some process cooling.

　　3. In principle, only the condenser is different. The air-cooled chiller cools the refrigerant in the condenser through a fan, and the water-cooled chiller takes away the heat in the condenser through cold water and dissipates it into the atmosphere through the cooling tower.

　　4. The water-cooled chiller can only be used for cooling, and other heating is required for heating, such as electric heating, steam heating, or a hot water boiler.

　　5. High-performance compressors imported from Europe and the United States are used, with high EER value, low noise and stable operation.

　　Advantages of air-cooled chillers

　　Air chillers cooling are often an excellent process cooling choice for water-cooled chillers because they are closed loop systems. Closed loop systems are capable of providing instantaneous cooling to plant processes and significant water savings by recirculating coolant/water.

　　Air chillers cooling are designed to be "plug and play" and easy to operate. The plug-and-play design closed-loop system is designed to minimize maintenance costs and reduce equipment life. Most of the regular maintenance that needs to be done on an air-cooled chiller is cleaning the condenser, keeping the water at a pH of 7, and making sure to maintain proper air circulation around the unit.

　　The significant advantage of the air chillers cooling are that the cooling capacity is moderate. The feature of the air-cooled chiller is that it is developed by the wind and converts the wind energy into the water energy required by the chiller.

　　Protection device for air chillers cooling refrigeration compressor

　　1. Internal thermostat (installed inside the compressor)

　　In order to prevent the 24-hour uninterrupted operation of the air chillers cooling, resulting in high-load operation of the compressor, poor electromagnetic switch, over current caused by shaft holding, etc., or motor burnout caused by the temperature of the motor, the compressor is installed inside the compressor. The internal thermostat, which is installed on the neutral contact of the three-phase motor, protects the motor by simultaneously cutting off the three phases in the event of an abnormality.

　　2. Electromagnetic switch

　　The electromagnetic switch is used to control the operation of the refrigeration compressor of the air chillers cooling. The purpose of the switch is to stop. The switch should be kept vertical during installation. If the installation is wrong, the spring pressure of the node will change and noise will be generated. , resulting in phase loss operation. For the compressor model with a direct power-off protector inside, it is not necessary to load the protector.

　　3. Reverse phase protector

　　The structure of the rotary compressor and the cylinder compressor needs to be different, because the reverse phase of the vortex reverse wind chilled water will cause the inability of hot and cold water, so the power supply is equipped with a reverse protector to compress the three-connected chiller. After the reverse phase protector is installed, it can run in positive phase, but not in reverse phase. When the reverse phase occurs, it can become positive phase as long as the two wires of the power supply are swapped.

　　4. Exhaust temperature protector

　　In order to protect the compressor under high load operation or insufficient refrigerant, it is necessary to install an exhaust temperature protector in the air-cooled chiller system. When the machine is shut down, this temperature value refers to the detected temperature of the compressor discharge pipe within 10cm from the outlet.

　　5. Low voltage switch

　　In order to protect the air chillers cooling compressor from running when the refrigerant is insufficient, a low-pressure switch is required. When it is set above 0.03mpa, the compressor will stop running. Once the compressor runs in a state of insufficient refrigerant, the temperature of the compressor part and the motor part will rise instantaneously. At this time, the low pressure switch can damage the compressor and the motor that cannot be protected by the internal thermostat and the exhaust temperature protector. Burn for protection.

　　6. High voltage switch

　　The compressor can be stopped when the high pressure pressure rises abnormally, and the operating pressure can be set below 3.0mpa.

　　Air chillers cooling are very important equipment for the industrial field. Compared with water-cooled chillers, air-cooled chillers are more environmentally friendly, energy-saving, and have high power, but the cost of one-time investment is relatively high, but no need follow-up investment work.

       The two industries with the most applications of air chillers cooling are:

　　1. High-speed spindle

　　This air-cooled chiller can be used in some high-speed spindles and motorized spindles. We all know that the development of many industries is inseparable from some spindles. It allows the machine to complete different operation requirements during the processing. For residential buildings, some heat will also be generated due to the rapid operation during the processing. In order to facilitate the dissipation of these heat, some equipment is required. Then this chiller equipment can be used, which can make the main shaft The temperature drops within a certain period of time to ensure the normal operation of the spindle.

　　2. Laser welding machine

　　In addition, this kind of equipment can also be used in laser welding machines. For this kind of laser welding machine, its rapid high temperature energy is used to achieve its welding technology. In order to improve the quality of welded products Even better, this chiller can also be used, which can make the product under high temperature plasticize rapidly in a short time, and can also ensure that the appearance of the product is smoother.

　　Air chillers cooling are mainly used in these fields. In fact, for this type of equipment, it can also be used in other fields, such as machining centers, grinders and cutting machines. Users can also choose according to You can choose different models reasonably according to your different processing needs. I hope this kind of equipment can play a good role in the processing of users.
