The main points of hotel central air-conditioning design and installation

At present, the central air-conditioning installation in hotels has become an irreplaceable project in modern hotels. It can not only bring fresh air, a comfortable environment, but also improve the beauty of decoration.

If the central air conditioner is installed well, it can make users more comfortable during use and can also increase the service life of the air conditioner. But we often overlook some details in the central air-conditioning installation in the hotel. Now Shanghai air conditioning design needs to analyze six details that need to be paid attention to:

Holes for interior and exterior walls

Before drilling holes, obtain the consent of the property to avoid damage to the wall structure. Drill holes on the inner wall to confirm the position of the hole in the room. For example, pay attention to the drill holes as close as possible to the middle of the room beam, usually on both sides of the beam; the outer wall is perforated, confirm the hole position, should be inclined to the outer wall side, Prevent rainwater from backlogging.

Pay attention to the dustproof installation of the internal machine

Indoor unit or fan coil protection: the indoor unit or fan coil is hoisted and protected from dust in time by plastic bags, cardboard and other materials to prevent dust and foreign objects from entering the machine.

The influence of installing the light trough in the internal machine

Due to the physical properties of the air, the hot air flow in winter always keeps rising. Therefore, it is important to maintain sufficient wind speed and adjust the angle of the blinds to ensure that the hot air reaches the height of movement of the personnel.

Once the lamp trough is encountered, the airflow cannot flow downwards, and the hot air always stays in the upper room, causing poor heat dissipation. Therefore, when heat is needed, do not insert the air outlet into the ceiling.

Heat dissipation and maintenance requirements of outdoor units

The distance between the return air side of the outdoor unit and the wall should be at least 200mm;

The outdoor unit should ensure enough space for heat dissipation.

The outdoor unit needs to be installed with buffer drainage

The outdoor unit needs to be installed horizontally, and the base or bracket has sufficient load-bearing capacity.

The base is made of rubber damping pads, and the bolts are firmly fixed.

The air conditioner maintenance reminder should consider the drainage of the outdoor unit to avoid the influence of defrosting water on the users downstairs.

Indoor drainage

Before installing the condensing pipe, determine its direction and elevation to ensure that the slope is straight and straight.

The slope of the condensing pipe should be more than 5 parts per thousand, and the slope of the drain outlet of the indoor unit for natural drainage should not be less than 1%.

Fix the condenser tube at 300mm at both ends of the corner.
