Central air conditioning system
The cold and heat sources of this system are centralized in the refrigeration station and boiler room, and the air handling equipment is centralized to form an air conditioning box, which is set in the machine room.

1.Advantage 1: High air tightness
As we all know, no matter whether it is conveying gas or relying on gas for material transportation, the gas conveying pipeline should avoid leakage. So, how does the round duct do this? It turns out that the pipe fittings of the round air duct and other parts connected to the duct have factory-assembled airtight joints.

If you want to keep your home heated all year round and, at the same time, you are tired of the lack of space, ducted air conditioning is what you need.

1.Basic content of air duct design
① Determine the shape of the air duct and select the size of the air duct.
② Calculate the pressure loss of the air duct. Through the calculation of the pressure loss along the way (friction) and local pressure loss of the air duct, the size of the air duct is finally determined and the fan is selected.

1.How to control the supply and return water temperature during system operation? What is the temperature difference between supply and return water in China's heating system?

1. Several issues that should be paid attention to during prefabrication (1) The bite form of the thin steel plate air duct in the clean system should adopt single bite, corner bite and combined corner bite with small bite seams.

1.Air System Design Principles
★It can guarantee the required indoor parameters, that is, it can guarantee to meet the indoor temperature, relative humidity, purification and other requirements under the design conditions and operating conditions.

Using a pre-insulated duct CNC cutting machine will definitely improve your duct making efficiency. A pre-insulated duct CNC cutting machine is a computerized cutting machine that cuts fast and accurately.

Fiberglass Duct Board is a 1- to 2-inch-thick rigid board (manufactured from resin-bonded inorganic glass fibers) used for the fabrication of fiberglass ductwork. For commercial applications that require thermal insulation, condensation control, and acoustic control, fiberglass duct board provides a low-cost, efficient alternative to sheet metal.

1. Shops and public areas
Large shops and department store areas generally use an independent all-air system, and the exhaust system is designed independently. The exhaust air volume is calculated as 80% of the fresh air volume. Select a fan.

1.Design of condensate system
The condensed water generated in the operation of fan coil units, integral air conditioners, combined air conditioning units, etc., must be discharged in a timely manner. The design of condensate discharge pipe adopts open, non-full flow artesian system.
