Modified phenolic formaldehyde is made of non-woven fabric and phenolic formaldehyde through continuous compounding and compounding, and it is compounded and compounded.

Galvanized steel
1. Process requirements
1) Bite connection or riveting should be used, and welding is not allowed;
2) The joints of the air duct panels should be staggered, and there should be no cross joints.

PIR Pre-insulated Duct is a high-tech foamed PIR duct panel, which is uniformly sprayed on color steel, aluminum foil, aluminum sheet and other surface materials by PIR raw materials, and foamed at a certain temperature.

Energy efficiency ratio: The energy efficiency ratio of an air conditioner is the ratio of cooling capacity (heating capacity) to operating power. That is, the mathematical expressions of EER and COP: EER=cooling capacity/cooling power consumption. COP=heating capacity/heating power consumption.

Polyurethane (PU) is the abbreviation of polyurethane, which is formed by addition polymerization of polyisocyanate and polyhydroxy polymer, and contains many repeating urethane segments (-NHCOO-) in the main polymer chain.

First, find out the air duct elevation according to the design requirements and refer to the civil engineering datum line.

Second, make hangers and high hanging points.

Ventilation, the "V" in HVAC, is often ignored. We pay great attention to heating and air-conditioning systems - their operation is critical to comfort, and heating and cooling can constitute an important part of the building utility bill. This can encourage people to reduce ventilation as much as possible, because the outdoor air must reach the indoor temperature and humidity level, whether in hot or cold weather, this is an expensive suggestion.

Design and selection of main equipment
1. Selection and calculation of fan coil units
2. Selection and calculation of fresh air air conditioning box
3. Selection calculation of combined air handling unit

Composite air duct is a kind of pipe that plays a role in air supply. It is different from traditional pipes. It does not produce harmful substances either during production or during production and installation.

Cooling Tower: Special equipment for cooling water by means of air. Generally installed on the top of the building. It is used in refrigeration, electric power, chemical industry and many other industries.

What is a fresh air system?

The fresh air system is an independent air treatment system composed of an air supply system and an exhaust system. It is divided into two types: ducted fresh air system and ductless fresh air system.

Composite air duct, represented by rubber plastic composite air duct, is a rubber plastic composite air duct system made of rubber plastic composite thermal insulation materials, which can comprehensively replace traditional air ducts, air valves, tuyeres, static pressure boxes, and thermal insulation materials in the air delivery system of air conditioners.
