Operating instructions for the chiller

Operating instructions for the chiller

Today, I will tell you about the operation instructions of the chiller. I hope to help you:

1, the machine installation program

2.1 Please check if the machine is damaged during installation and choose the right place for installation and future maintenance.

2.2 The site where the unit is installed must be the floor, mounting mat or foundation, its level is within 6.4mm, and can withstand the operating weight of the unit.

2.3 The unit should be placed in a machine room with a room temperature of 4.4-43.3 °C. There should be enough space around and above the unit for routine maintenance work.

2.4 At the end of the unit, leave a pipe space for cleaning the condenser tube bundle, or use a door hole or other suitable hole.

2.5 Select the water pipe of the appropriate pipe diameter, the cooling system and the cold water system of the maximum power operation of the unit, and connect them correctly.

2.6 For normal applications, the water flow rate through the evaporator and condenser is allowed to be between 1.0 and 3.6 m/s.

2.7 Water flow should be stable under any load conditions.

2.8 All chilled water and cooling water piping shall be designed and installed in accordance with conventional methods. The chilled water pump shall be located on the inlet pipe of the unit to ensure positive pressure and flow within the unit. The piping should be provided with a damping tube to ensure proper flexibility, and to prevent the evaporator water from being drained when the pump is shut down.

2.9 Pipes should have strong support independent of industrial chillers to avoid stresses on the components of industrial chillers. The hangers are set up to facilitate pipe alignment.

2.10 In order to reduce noise and vibration, it is best to install a vibration isolator on the pipeline.

2.11 In order to use industrial chillers economically and efficiently, it is recommended that water treatment experts analyze the water quality of the evaporator and condenser. Poor water quality will cause fouling to affect heat transfer, or cause corrosion and sedimentation, breeding of organic matter, and affecting the performance of the unit. Increase operating and maintenance costs.

2.12 In general, proper water treatment and periodic cleaning of the bundle can maintain its good performance. If the existing water quality conditions cannot be improved by appropriate methods, then it is necessary to consider allowing the bundle to have a large fouling factor or designating a special Structural material.

2.13 Please install a filter at the inlet of the water pipe and clean it regularly.

2.14 After the test leak is completed, all the nozzles must be rust-proofed.

2.15 In order to facilitate routine maintenance work, users can take the following (or all) measures:

a) Pressure gauges and globe valves with cocks can be installed on the inlet and outlet pipes of cooling water and chilled water, as close as possible to industrial chillers;

b) Hanging rails and beams can be placed above the equipment for easy maintenance.
