Description of the training Refrigerating units and  aircoolers :

Refrigerating units and  aircoolers

Objective:
To be able to recognize different types of chilled water production units and indicate their principle characteristics.
To be able to recognize the different types of air coolers and indicate their principle characteristics.

Level: A Level / High School Certificate (HSC)

Contents :
1) Presentation of refrigerating machines  – HSC
2) Air cooled chilled water production units – HSC
3) Water cooled chilled water production units – HSC
4) Dry coolers – HSC
5) Wet air cooling systems – HSC
6) Energy saving advantages of wet air cooling systems – HSC

Guidance:
There are many types of chilled water and air-cooling units. To be able to recognize and understand their utility is useful for all technicians dealing with large air-conditioning installations.
The training level and difficulty is indicated at the end of each section heading.

Required E-book chapters:
General presentation of refrigerating machines

 

Cooling floors and ceilings and chilled beam technology – HND Level

Objective:
To be familiar with the technology of air conditioning units using radiation as a means of exchange and induction or air density as a means of displacement

Level: HND Level

Authors: Patrick Delpech, Etienne Hoonakker

Contents :
1) Convector and radiant systems
2) Cooling ceilings
3) Cooling floors
4) Passive chilled beams
5) Induction convectors
6) Active chilled beams
7) Installation of active chilled beams

Guidance:
The mastery of air conditioning loads means that these systems are much easier to use than before. The absence of a fan facilitates maintenance and ensures silent operating. The study of cooling floors and ceilings and chilled beams has therefore become highly topical.

 

 

Selecting cooling floors and passive chilled beams – HND to Master’s level

Objective:
To know the principles of cooling floors, cooling ceilings and passive chilled beams selection

Level: HND to Master’s Level

Authors: Patrick Delpech, Etienne Hoonakker

Contents :
1) Convector and radiant systems
2) Cooling ceilings
3) Cooling floors
4) Passive chilled beams
5) Induction convectors
6) Active chilled beams
7) Installation of active chilled beams

Guidance:
The study of cooling floor, cooling ceiling and passive chilled beam sizing is an excellent learning process of the behaviour of passive air-conditioning equipment.

The training levels indicated at the end of the title of each section specify the difficulty.

Before studying the chapter, download and print the question book (right hand link). Write out your answers before checking on-line.

Required section study:
“Cooling Floors, cooling ceilings and chilled beams” and “Selecting hot water emitters”

 

Selecting Induction units and active chilled beams – HND to Master’s level

Objective:
To be able to select induction units and active chilled beams

Level: HND to Master’s Level

Authors: Patrick Delpech, Etienne Hoonakker

Contents :
1) Induction unit performance
2) Induction unit selection
3) Active chilled beam ouputs
4) Active chilled beam selection
5) Active beams in heating mode

Guidance:
he selection of induction units and active chilled beams is difficult. The study of this useful document for design office technicians has a high learning value. The levels of training indicated at the end of each chapter title represent their complexity.

Required reading:
Cooling floors, ceilings and passive chilled beams
