How to install the fresh air unit in the clean workshop?
Fresh air conditioning unit is mainly composed of air filter, cooling heat exchanger and blower unit. Common fresh air unit air conditioners are vertical, horizontal and ceiling type. Before installation, you should understand its structural characteristics and installation points in detail. ; The ceiling-mounted new ventilation unit air conditioner is hoisted on the roof. Considering the load-bearing aspect, the air volume of the unit does not exceed 8000m3/h in general. , and some reach 20000m3/h, but there must be guarantee measures during installation; reasonably choose the diameter of the boom to ensure hanging installation; if the air volume and quality of the unit are not too large, and the vibration of the unit is small , The top of the boom is connected to the roof with expansion bolts, and the bottom of the boom is connected with a screw thread and a rubber vibration damping pad to connect with the hoisting hole. .
When installing the unit, special attention should be paid to the direction of the air inlet and outlet of the unit, the direction of water inlet and outlet, and whether the extraction direction of the filter is correct, etc. When installing the unit, water leakage should be prevented at the connection of the pipeline, and the insulation material of the unit condensate pan should be protected. , do not expose the condensate pan, and pay special attention to protect the connection threads of the inlet and outlet pipes and the condensate pipes, and wrap the sealing material; reasonably consider the vibration of the unit, and take appropriate vibration reduction measures. A vibration damping device has been installed between the blower inside the unit and the bottom frame of the box; if it is a small-sized unit, you can directly connect the boom to the unit's hoisting hole with screws and washers.

At the same time, the cooling and heat exchanger should have no leakage, and a water test should be carried out. During the water test, the air should be discharged through the air release valve on the upper part of the cooling and heat exchanger to ensure that the system pressure and The water system is smooth.
