It consists of speed fan and heat exchanger coil two parts, fan is generally composed of forward tilting blade and low noise motor, generally three wind speed, motor for the tapping speed, by speed switch on different tapping, control the motor operating voltage to realize the speed control. Coil is a high-efficiency finned heat exchanger, which is made of purple copper tube and hydrophilic aluminum fins by high-pressure expansion, and it is the component of cooling and heating air, in addition to condensate tray, air filter and other accessories.

If the waste heat of data center is used to supply heat directly, it requires that the heat discharge of data center is always greater than the user heat load, and it is difficult to achieve a complete match in the time domain.

Practical air conditioning and ventilation system installation knowledge sharing
Duct Sheet Selection:
Basis: GB50243-2016 “Ventilation and Air Conditioning Engineering Construction Quality Acceptance Specification”.
4.1.4 The air duct system shall be divided into four categories of micro-pressure, low-pressure, medium-pressure and high-pressure according to its working pressure, and the air ducts of the corresponding categories shall be used. Duct category should be divided according to the provisions of Table 4.1.4.

It is a multi-outdoor-unit solution that carefully computes the precise amount of refrigerant required by each indoor
unit to achieve individualized temperature control for each comfort zone.
Because of its flexibility, VRF systems can be customized to meet the specific demands of any project. It controls the
refrigerant flow according to the heat load requirement to avoid over cooling or heating effectively.

The cooling capacity of air conditioners for home use is directly related to the room area, sealing conditions, the number of people, the degree of sunlight exposure and other factors.
Before purchasing an air conditioner, it is best to choose a suitable model and power reasonably according to the size of the room area and air circulation.
