industrial refrigeration

Chillers can generally be divided into water-cooled and air-cooled according to their refrigeration forms. Technically, water-cooled units have an energy efficiency ratio 300 to 500 kcal/h higher than air-cooled units; In terms of price, water cooling is much lower than air cooling;
Features of water-cooled screw chillers:
1. The most efficient semi enclosed compressor, the heart of the unit - imported high-quality screw compressor, with a 5:6 ultra efficient screw rotor compressor, which has an energy efficiency 20-30% higher than ordinary compressors. It has high reliability, high efficiency, easy maintenance, precise capacity control, and a wide range of applications.
2. The microcomputer accurately controls the temperature, and the microcomputer controller of the unit adopts a large screen lattice LCD display, which has a good Chinese human-machine dialogue interface to achieve full functional automation control. The LCD display screen instantly displays the working condition of the machine, accurately monitors the operation of the group in the best state, and its touch panel is well sealed, waterproof, dustproof, corrosion-resistant, and has a long service life of the keys. Graded and infinite energy control, used for general air conditioning systems, equipped with 100%, 75%, 50%, and 25% graded energy control systems. This ensures that the unit can achieve maximum energy efficiency under partial load. However, if precise control of water temperature is required, all models can be equipped with infinite energy control according to user requirements
3. High operating efficiency, the heat exchanger adopts high-efficiency corrugated tubes, coupled with high-efficiency screw compressors, ensuring the high-efficiency operation of the unit. The most reliable protection and auxiliary components
4. The chiller unit has the following components to prevent any operational faults: compressor protection design timer, overcurrent relay, compressor motor temperature sensor, anti freezing temperature controller, sight glass, oil heater, compressor reverse phase protection relay, high and low pressure protection, exhaust high temperature protection, safety valve, and soluble plug
5. Latest asymmetric rotor tooth profile
6. Four stage or stepless capacity control system
7. Built in pressure differential oil supply lubrication system
8. Low vibration and low noise
9. The water-cooled chiller unit adopts a horizontal shell and tube condenser and a shell and tube evaporator. It has the characteristics of simple structure, stable heat exchange, long-lasting efficiency, and easy maintenance, and has been recognized as the most ideal structural composition for central air conditioning hosts.
10. The unit control system adopts an imported PLC program controller, and the human-machine interface is equipped with a large screen touch screen. The interface is simple and generous, and the operation is intuitive and simple.
11. The unit is equipped with reliable safety protection devices, including: high and low pressure protectors, exhaust overheat protectors, compressor motor overheat protectors, overload current protectors, antifreeze temperature protectors, water flow protectors, emergency stop switches, temperature sensitive fusible plugs, safety valves, etc.
