1. As the heart of the refrigerator, the compressor is a semi-closed screw compressor in Hanzhong, Taiwan Province, with only three moving parts, which has the characteristics of few parts and low failure rate.
2 Evaporator (titanium tube type, 3 16L stainless steel type) and condenser are made according to the national material use index of refrigeration industry, and the payment is within 1%;
Expansion valves, filters, high and low pressure gauges, solenoid valves and other refrigeration components are made of internationally renowned brands such as French, Taiwan Province and Japanese, with high precision, low failure rate and long service life.
4. Japanese electronic thermostat can accurately control the water temperature within the range of +5℃ to +35℃, and the temperature difference is+1℃. 5. All the controls are set on the front of the refrigerator. Just press the switch and adjust it to the required temperature, so it can be operated automatically, which is simple and fast.
6. Equipped with compressor overload protection, pump overload protection, high and low pressure abnormal protection, insufficient water level protection, anti-freezing protection, electronic delay and other safety protection devices, as well as abnormal alarm buzzer and fault indicator alarm system, which can automatically cut off the circuit, safe and reliable.
compressor
Internationally famous brand screw refrigeration compressor, patented technology in Europe and America.
Efficient 5: 6 third generation asymmetric tooth screw with the most advanced shape.
Semi-closed design, with only three moving parts, has the characteristics of few parts and low failure rate.
It can realize graded or stepless energy regulation, flexible and convenient control, energy saving and high efficiency, and easy maintenance.
The world-famous SKF and FAG zero clearance multi-thrust and radial bearings are selected, with precise structure and high reliability.
The three-stage oil separation filter has good oil filtering effect, which effectively ensures the normal operation of the compressor and efficient heat exchange of the heat exchanger.
Pump-free built-in differential pressure oil supply lubrication system is energy-saving, efficient and reliable.
Special fluorine-resistant low iron loss motor design, equipped with reliable motor overheating protection device, effectively ensure the efficient and reliable operation of the motor.
Equipped with liquid refrigerant injection system under low temperature and heat pump conditions, the workload and exhaust temperature of key components can be effectively reduced, and the working reliability of the compressor can be improved.
Patented exhaust chamber design and rotor continuous gas transmission ensure low vibration and noise of compressor.
The exhaust check valve installed at the exhaust port can prevent the water-cooled condenser from reversing when the rotor is stopped.
The washable water-cooled condenser adopts reinforced heat exchange tubes (with ribbed outer fins) and is expanded on the tubesheet. The design pressure of water side is 10bar, and the design pressure of fluorine side is 25 bar, and it is equipped with safety valve to ensure the safety of equipment.
Liquid path control valve
Adopt imported ball valve to effectively reduce the resistance of refrigerant liquid pipeline; At the same time, when the filter element is dirty and blocked, it is convenient to replace the filter element and clean the filter cartridge.
Drying and filtering device
Welding angle filter is adopted, and its filter element is imported molecular sieve. It can filter impurities such as water and acid, and it is convenient to replace.
Expansion valve
The imported thermal expansion valve is used to throttle and cool the low-temperature and high-pressure supercooled liquid into low-temperature and low-pressure liquid, and automatically adjust the refrigerant flow into the evaporator according to the evaporation temperature to maintain a certain pressure, thus ensuring the evaporation rate in the evaporator.
Economizer
The imported plate heat exchanger is used to further increase the supercooling degree of refrigerant and improve the refrigeration capacity, and the single-stage compression is changed into quasi-two-stage compression, thus improving the efficiency of the compressor itself. The configuration of economizer improves the refrigeration efficiency and reduces the operating cost of the unit.
electrical control system
The main components are imported to ensure the reliability of the unit operation. The device is controlled by PLC touch screen, which makes the operation easier.
