Stand Alone Chiller System for Process Chilled Water

Stand Alone Chiller System for Process Chilled Water

A chiller is a cooling device that can provide constant temperature, constant flow, and constant pressure. It can also be called a constant temperature chiller. The principle of the chiller is to inject a certain amount of water into the internal water tank of the machine, cool the water through the chiller refrigeration system, and then the water pump inside the machine injects low-temperature frozen water into the equipment that needs to be cooled, and the chilled water transfers the heat inside the machine Take it away, and return the high-temperature hot water to the water tank again to cool down, so that the cooling is circulated and exchanged to achieve the effect of cooling the equipment.

◆Excellent performance

1. The main engine adopts the international advanced semi-hermetic screw rotor compressor, and the motor and compressor adopt an integrated design without shaft seal leakage, which is 20%-30% higher in energy efficiency than ordinary compressors;

2. Two compressors or multiple compressors have a start-up and stop cycle control program, which can balance the load and prolong the service life of the unit;

3. Two compressors or more units adopt multiple refrigeration circuits. When one of the circuits needs to be repaired and maintained, the other circuits can still operate normally and have a backup function;

4. The compressor is started by unloading and step-down to avoid impact on the power grid.

5. The chilled water outlet temperature of the chiller can be controlled above 5°C;

6. The unit can be equipped with an environmentally friendly and energy-saving heat recovery device as needed, which can produce free hot water during cooling.

◆Easy to install

1. The chiller unit has a compact structure and a small footprint, saving space in the machine room;

2. When the whole machine leaves the factory, it has been strictly debugged and fixed to complete, and it has fully reached the design state;

3. The vibration of the unit is very little, the foundation does not need special vibration isolation measures, and the installation is simple;

4. Only need to connect the evaporator chilled water and condenser cooling water pipes during installation.

5. The chiller unit can carry out intelligent program control according to the load change: 100%, 75%, 50%, 25% (or start), 0, saving energy consumption;

◆Complete security protection functions

1. Pressure protection: high-pressure and low-pressure automatic protection device for the refrigeration system of the chiller;

2. Power supply protection: undervoltage protection, phase loss protection, reverse phase protection, overload protection, motor overheat protection;

3. Antifreeze protection: when the chilled water temperature is too low, the unit will automatically stop;

4. Safety valve protection: When the refrigerant pressure exceeds a certain value, the safety exhaust valve will automatically open;

5. Delay protection: Delay start protection of the chiller compressor to prevent the compressor from starting frequently;

6. Water flow protection: When the water flow stops or drops, continuing to run will endanger the equipment, and the equipment will automatically shut down.
