Water Cooled Screw Chiller Mature Technology
- Jun 30, 2017 -

Water-cooled semi-sealed screw chillers are a central air-conditioning product with water as the cooling medium. Compared with the same cold air-cooled units, Water Cooled Screw Chiller the condenser and the evaporator are made of special high-efficiency heat transfer tubes, so the structure is compact , Small size, high efficiency; and because there is no condensing fan, Water Cooled Screw Chiller so the noise is low.

In the water-cooled semi-sealed screw chillers manufacturing has a mature technology, improve the technology and advanced detection equipment, coupled with the selection of world-class accessories to ensure that the unit's stable and efficient operation.

Water-cooled semi-closed screw chillers can provide cold water for central air-conditioning systems such as hotels, hospitals, pharmaceutical plants, theaters, stadiums, Water Cooled Screw Chiller recreation centers, commercial buildings, industrial and mining enterprises, etc., but also for textile, chemical, food, electronics and scientific research And other departments to provide refrigeration and so on.

1, the unit should have a dedicated room, and should take measures to run the unit when the heat generated from the engine room, ventilation can be maintained at room temperature does not exceed 35 ℃ requirements.

2, the unit should be installed in the deformation of the rigid base or concrete foundation, Water Cooled Screw Chiller the foundation should be flat surface, should be able to withstand the weight of the unit when running.

3, the unit should be surrounded by drainage ditch and other sufficient drainage capacity of the drainage measures in order to stop the seasonal operation or maintenance of the system when the water discharge system.

4, the engine room should have enough space for the installation and maintenance of the unit; room should have sufficient extubation space; the top of the compressor should not lay the pipe and pipe.

5, it is recommended to install the water pipe and the unit to take over the size of the installation of isolation between the isolation of rubber to take the distance, Water Cooled Screw Chiller so that the unit arrived at the scene after the appropriate construction and adjustment space.

6, in order to make the electrical components work properly, do not put the unit in the dust dirt, corrosive smoke and humidity, if there is such a situation, must be corrected.

7, should prepare the materials and tools: soft joints, Water Cooled Screw Chiller shock pads, lifting equipment, lifting beams, hanging chain, jack, sliding pad wood, pad roll, pry bar.

For installation or maintenance reasons, the need for on-site refrigerant charging, the operation is as follows:

Use nitrogen positive pressure leak detection qualified.

Vacuum pump the unit vacuum to -0.1Mpa.

After the vacuum has passed, (if the water system is filled with water), Water Cooled Screw Chiller make sure the pump is open and the heat exchanger is in the flowing state, and the prescribed refrigerant is injected through the corner valve filling hole at the bottom of the condenser.

In order to avoid corrosion and overheating of the terminal connections, Water Cooled Screw Chiller it is required that all the supply lines be copper conductors. Control cable and power cord to be laid separately and protective tube to prevent the power cord to interfere with the control cable, the unit shell must be reliably grounded.
