Information

When installing a chiller, there are many things to be aware of, so as not to cause the chiller to operate in the future. We need to follow the steps below to install the chiller:

First: the choice of installation site

(1) The site must be a floor and a mounting mat with a level of 6.4 mm and can withstand the operating weight of the unit.

(2) 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.

Second: correct water treatment

(1) In order to use the chiller economically and efficiently, it is recommended that the water treatment expert analyze the water quality of the evaporator and condenser. The bad water quality will cause the scale to affect the heat transfer, or cause corrosion and sedimentation, breeding organic matter, and affecting the performance of the unit. Increase operating and maintenance costs. Please install a filter at the inlet of the water pipe and clean it regularly.

(2) 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 Specify special structural materials.

Third: the arrangement of the pipeline

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

(2) After the test leak is completed, all the nozzles must be rust-proofed.

(3) At the end of the unit, the pipe space for cleaning the condenser tube bundle should be left, and the door hole or other suitable hole can be used.

(4) The pipe should have a firm support independent of the chiller to prevent stress from being applied to the components of the chiller. The hangers are set up to facilitate pipe alignment.

(5) The design and installation of all chilled water and cooling water piping shall be carried out 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 in the unit. Damping tubes should be provided for piping to ensure proper flexibility.

Fourth: water flow control

(1) 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) Under any load, the water flow should be stable and the water in the evaporator should be prevented from being drained when the pump is shut down.

Fifth: attention points and safety measures

(1) In order to reduce noise and vibration, it is best to install a vibration isolator on the pipe.

(2) Hanging rails and beams can be erected above the equipment for easy maintenance.

(3) 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 the chiller.
