Water cooled screw heat recovery unit

Product Details

Product Introduction

1. Compact structure, smooth operation:
The condenser and dry evaporator of the water-cooled screw heat recovery chiller unit both use high-efficiency heat transfer tubes, and the main engine adopts imported high-efficiency semi closed twin-screw compressors, which have many advantages such as compact structure, small volume, light weight, and small position. The semi enclosed twin-screw compressor has fewer moving parts and uses a 5:6 ultra efficient screw rotor. There is no direct wear between the rotors, making it highly reliable. Due to the fact that the screw machine is a continuous compressor without pulsation, the unit has the characteristics of stable performance, low noise, small vibration, and smooth operation. Improved efficiency by 20% -30% compared to reciprocating compressors, and has obtained IS09001 international quality certification and patents from multiple European and American countries;
2. A comprehensive energy control system:
The water-cooled screw heat recovery chiller unit has a four level capacity control system, with energy regulation of [100, 75, 50, 25 (or start, 0%)], and automatically adjusts the unit start and stop according to load changes, making it more energy-efficient. During operation, the computer control system will adjust the energy output of the water-cooled screw heat recovery chiller based on changes in the client's thermal load. The microcomputer quickly determines and sends a signal to push the slide valve to the required energy by monitoring the difference between the actual load measured and the user's setting. And in multiple systems, working in an optimized way that minimizes energy consumption with the best cooling output not only demonstrates excellent performance at full load, but also has high operating efficiency even at partial load;

3. Independent operation of refrigeration system:
The large capacity water-cooled screw heat recovery chiller unit has two or more independent refrigeration circuits, so even if one circuit fails/needs maintenance, the other circuit can still operate normally. Equipped with backup function, especially suitable for industrial non-stop environments;
4. Easy and intuitive operation:
The water-cooled screw heat recovery chiller unit adopts a microcomputer programmable controller (PLC Chinese or English display), with a touch screen display. According to the menu selection on the screen, the operation can be started by simply tapping the display button on the screen with your finger. The screen can display the operating status of the unit at any time, and can display parameters in two ways: graphics and text tables, making it clear at a glance;
5. The protection function of microcomputer controller:
It has protection functions such as compressor coil temperature high protection, oil preheating timed power on/off, cold water flow switch, cold water outlet temperature low protection, Y - △ start failure protection, exhaust temperature high protection, compressor overload protection, power-off memory function, frequent start stop protection, voltage abnormality protection, low oil level protection, high and low voltage protection, etc;
6. Multiple protections, safe and reliable:
In addition to the internal protection module of the compressor providing functions such as overpressure, phase loss, and overload protection, the pressure control device of the refrigeration system of the water-cooled screw heat recovery chiller can ensure that the unit works perfectly;
7. Easy to install:
The water-cooled screw heat recovery chiller unit has completed all component installation, operation testing, and refrigerant and refrigeration oil filling in the factory. Users only need to connect the water and circuit to put it into use, reducing installation and commissioning time;
