Low Temperature Water Cooled Chiller

low temperature water cooled chiller

Features and advantages of low temperature water cooled chiller

1. Compact structure and stable operation: the condenser and dry evaporator of the low temperature water cooled chiller adopt high-efficiency heat transfer tubes, and the main engine adopts imported high-efficiency semi-hermetic twin-screw compressors, which have compact structure, small size and light weight , small installation location and many other advantages. The semi-hermetic twin-screw compressor has few moving parts, and the compressor adopts a 5:6 ultra-high-efficiency screw rotor. There is no direct wear between the rotors, and the reliability is high. Since the screw machine is a continuous compressor without pulsation, the low temperature water cooled chiller has the characteristics of stable performance, low noise, small vibration and smooth operation. Compared with the reciprocating compressor, the efficiency is increased by 20%-30%.

2. Perfect energy control system: the low temperature water cooled chiller has a four-level capacity control system, which automatically adjusts the start and stop of the unit according to the load change, which is more energy-saving. During operation, the computer control system will change the energy output of the unit according to the change of the heat load of the client. The microcomputer quickly judges the difference between the measured actual load and the user’s setting and sends a signal to push the slide valve to the required energy. And in multiple systems, it works in an optimized way with the least power consumption at the best cooling output, not only showing excellent performance at full load, but also has high operating efficiency even at partial load.

3. Independent refrigeration cycle system: low temperature water cooled chiller has two or more independent refrigeration circuits, even if one circuit fails/maintains, the other circuit can still operate normally. With standby function, it is especially suitable for industrial non-stop environment.

4. Simple and intuitive operation: low temperature water cooled chiller adopts microcomputer programmable controller, touch screen display, select operation according to the menu on the screen, and directly touch the display button on the screen with your finger to start the unit. The screen can display the operating status of the unit at any time, and can display the parameters in two ways: graphics and text tables, which are clear at a glance.

5. The protection function of the microcomputer controller: low temperature water cooled chiller has the protection of the high temperature of the compressor coil, the timing switch of the oil preheating, the cold water flow switch, the protection of the low temperature of the cold water outlet, the protection of the failure to start, and the protection of the exhaust temperature. High protection, compressor overload protection, power failure memory function, frequent start and stop protection, abnormal voltage protection, low oil level protection, high and low voltage protection and other protection functions.

6. Multiple protections, safe and reliable: In addition to the low temperature water cooled chiller internal protection module of the compressor providing over-undervoltage, phase loss, overload and other functions to protect the compressor, the pressure control and other devices of the refrigeration system can make the unit work without any risk.

7. Freezing medium: low temperature water cooled chiller uses ethylene glycol antifreeze, and can also be designed to use salt water as antifreeze according to user requirements.

8. Easy to install: the low temperature water cooled chiller has completed all the component installation, operation test, and filling of refrigerant and refrigeration oil in the factory. The user only needs to connect the waterway and the circuit to put it into use, reducing installation and debugging time.
