Functions：
1- Centrifugal Compressor 2- Refrigerant R134a 3-Cooling
Frame Structure Description：
1.Floor adopts outer surface of the unit has been doing polyester spraying process of galvanized steel plate, make the whole unit should not be rust.
2.Convenient, compact structure, simple unit.Easy to fully grasp the running state of unit, the evaporator and condenser in the process of transportation, room installation and daily operation effective protection effect and make the maintenance more convenient.Units inside decorate after three dimensional optimization design, layout is compact, the optimized shape proportion, need to the maintenance of the space is little, take up room area is small, save space.
Compressor Description：
1. The compressor adopts a two-stage compression belt with an intermediate economizer air supply structure, and uses a high-strength alloy main shaft, a high-strength aluminum alloy enclosed impeller, and a high-precision aviation-grade precision gear.
2. The impeller cast with special aluminum alloy is designed with the most advanced NREC centrifugal compressor design program in the world, which ensures the high precision and high efficiency of the impeller.
3. High-strength ball/roller bearings are used, which are not ordinary sliding bearings, so the compressor is not afraid of emergency stop, and a high-level oil tank is not required; start the compressor 3 seconds in advance and turn on the oil pump, so that the lubricating oil is not easy to enter the system; the start-up interval can be shortened to 8 minutes.
4. The motor and the compressor are integrated, and the flange seal is adopted, which eliminates the necessary connection and sealing device between the motor and the compressor for the open motor, reduces the wearing parts, and eliminates the problem of refrigerant leakage. Liquid refrigerant is used for evaporative cooling. , The motor temperature rise is low, the noise is low, the efficiency is high, the service life is long, and the machine room only needs general ventilation equipment.
Evaporator Description：
1.Evaporator is modified to enhance the heat transfer effect, improve system evaporation temperature, increase unit cooling capacity and improve the efficiency of the unit operation. Special technology of spray type internal structure design and reasonable evaporation space can reduce evaporation resistance. Refrigerant liquid can complete recycle without additional power by using the refrigerant flow control circulating pump. The tube cluster in evaporator can fully infiltrated and improve the heat transfer performance effectively even units are running without precisely adjusting.
2.High heat transfer efficiency of spirals inside thread copper pipe, increase the heat exchange area and refrigerant disturbance, improve the effect of heat transfer.
3.The design, manufacture and inspection of the evaporator comply with national standards and regulations for pressure vessels such as GB / 150 steel pressure vessels and JB / 4765 pressure vessels for refrigeration devices.
Condenser：
1.Shell and tube heat exchanger with efficient double thread copper pipe, increases the shell side between the refrigerant and cooling water tube side heat transfer effect.
2.Condenser uses the unique way of admission, uniform distribution of refrigerant flow, extend the condensation distance, make the heat transfer effect is best.Also increase the degree of supercooling unit, which can effectively improve the efficiency of unit cycle.
3.The design, manufacture and inspection of the evaporator comply with national standards and regulations for pressure vessels such as GB / 150 steel pressure vessels and JB / 4765 pressure vessels for refrigeration devices.
Control Cabinet：
1.The unit startup and microcomputer control parts are integrated into the same control cabinet and located at the front of the unit, which is convenient for the on-site operators to operate in the machine room and between the units. The maintenance of all electrical parts can be carried out at the front of the unit.
2.The electrical control box is made of high-quality steel plate, and the external surface has been galvanized and anti-corrosion treatment, which can effectively protect the electrical components of the unit.
3. For the safety of the operator, once the host is powered on, the operator will not be able to open the isolation board between the control and electrical components to ensure the safety of the operator.
