3.water system
(1)The diameter reduction of PP-R pipes must be less than 3% when hot-melted, and the installation must meet the technical requirements of the manufacturer.

2) Air treatment process of fan coil unit + fresh air air conditioning system

The fresh air and the fan coil unit supply air to the air-conditioned room respectively. In this way, even if the fan coil unit stops running, the fresh air will remain unchanged.

When many carpenters are making suspended ceilings, they do not design the return air vent properly, and even seal the return air vent, which greatly affects the use effect of the air conditioner, and even greatly reduces the life of the air conditioner.

Nowadays, ventilation systems have become increasingly essential elements within homes, taking charge of renewing the air and reducing the high levels of humidity in the home.

1.Device Installation
(1)The installation location of the main unit of the air conditioner should be convenient for maintenance without affecting its function. Pay special attention to heat dissipation. When there are multiple hosts in the computer room, the connection direction and operation surface of all hosts must be in the same direction.

The air conditioning system generally consists of air handling equipment and air delivery pipes and air distribution devices. According to the needs, many different forms of the system can be composed.

Step 1: Familiarize yourself with the original design information for designing the building

Including: documents provided by the construction party, construction use and process requirements, design assignment, construction work drawings, etc.

The high precision and high efficiency of the CNC cutting machine make many customers overjoyed. Today, I will introduce some reasons for purchasing the CNC cutting machine:

In the air duct conveying system, in order to make the air flow evenly sent to each machine room, it is necessary to send a certain amount of air through the air outlet with a certain shape, area and different air flow directions.

Using rubber-plastic insulation, the construction is simple, the appearance is beautiful, the process is simple, the construction cost is effectively reduced, and the insulation effect is good.

1. Cutting accuracy
The cutting accuracy highly affects the utilization rate of the air duct sheet. For the construction industry, it is generally required to be less than ±0.5mm; for the pre-insulation and heat preservation air duct cutting, the general requirement is not to exceed ±0.3mm.

In recent years, the rapid development of industrial economy has correspondingly enhanced the production capacity of enterprises. In the process of technological transformation, it directly affects the air quality in the plant, makes operators feel uncomfortable, and further reduces the production level.
