2.2 Installation Preparation (Site Preparation)
The CRV+ series of air conditioners is streamlined for maintaining a favorable environment for data
centers, computer rooms, and similar ecosystems. Strict adherence to the installation procedures is
mandatory in order to ascertain proper installation of the air conditioner.
2.2.1 Equipment Room Requirement
The equipment room must be prepared to ensure a smooth operation flow and obtain accurate results.
The equipment room must meet the standards for appropriate ventilation and heating. The design
specifications for the air conditioners must be ideal and should match the energy-efficient design
standards.
Following are the requirements for maintaining a favorable room environment prior to installation:
The equi
pment room should be well insulated and have a sealed damp-proof layer.
The outdoor air entering in should be kept at a minimum. The outside air will add the loads of
heating, cooling, humidifying, and dehumidifying of the system. It is recommended that the
inhalation of outside air be kept below 5% of the total indoor airflow.
All the doors and windows should be properly sealed to minimize the leakage. The seams should
be as narrow as possible.
